The height of a triangle is 3 m

more than twice the length of the

base. The area of the triangle is

76 m2. Find the height of the triangle. Help me!

Answers

The triangle has a height of 19 meters.

How to determine the height of a triangle

In this problem we find the area of a triangle, in square meters, and the relationship between its height (h) and its base length (b), both in meters. We must solve the following expression to determine the height:

A = (1 / 2) · b · h

h = 3 + 2 · b

A = 76

Then,

76 = (1 / 2) · b · (3 + 2 · b)

152 = b · (3 + 2 · b)

152 = 3 · b + 2 · b²

2 · b² + 3 · b - 152 = 0

Finally, we find the roots of the polynomial by quadratic formula:

b₁ = 8, b₂ = - 19 / 2

Since, lengths are non-negative real numbers, the only possible solution is b = 8 and the height of the triangle is:

h = 3 + 2 · 8

h = 19

The height of the triangle is 19 meters.

Four friends participated in a free contest for charity. Erin scored 4 less points than Taylor. Nya scored three times as many points as Erin. Aaron scored 10 more points than Nya. Together the four friends scored a total of 158 points. Find how many points each friend made :How many points Taylor scored :Erin scored : Nya scored :Aaron scored:

Answers

Taylor's scored 22 points

Erin scored 18 points

Nya scored 54 points

Aaron scored 64 points

Explanation:

Let Taylor's point = x

Erin scored 4 less points than Taylor:

Erin's score = x - 4

Nya scored three times as many points as Erin:

Nya's score = 3(x - 4)

Aaron scored 10 more points than Nya:

Aaron's score = Nya's score + 10

= 3(x - 4) + 10

The total score of the four friend = 158 points

Taylor's score + Erin's score + Nya's score + Aaron's score = 158

x + (x - 4) + 3(x -4) + 3(x-4) + 10 = 158

Expand the parenthesis:

x + x -4 + 3x - 12 + 3x - 12 + 10 = 158

collect like terms:

x + x + 3x + 3x - 4 - 12 - 12 + 10 = 158

8x - 18 = 158

8x = 158 + 18

8x = 176

Divide both sides by 8:

8x/8 = 176/8

x = 22

Taylor's scored 22 points

Erin scored : x-4 = 22- 4 = 18 points

Nya scored : 3(x-4) = 3(22-4) = 3(18) = 54 points

Aaron scored: 3(x-4) + 10 = 54 + 10 = 64 points

How to find the equation of a line?

The equation of a line can be represented in different form such as slope intercept form, point slope form and standard form.

The equation of the line can be written is slope intercept form as follows:

y = mx + b

where

m = slopeb = y-intercept

Therefore, using the coordinates (0, - 70)(-20, -30)

Let's find the slope,

m = slope = -30 + 70 / -20 - 0

m = 40 / - 20

m = - 2

Let's find the y-intercept using (0, -70)

-70 = -2(0) + b

Solve the following simultaneous equation using the inverse matrix method

Answers

The values of x and y obtained by inverse matrix method are 2 and 3 respectively

What is an inverse matrix?

An inverse of a matrix, A, is a matrix [tex] A^{-1}[/tex], that multiplies matrix A to give an identity matrix.

The inverse matrix method involves defining and making use of a coefficient matrix, A, a variable matrix, X, and a constant matrix, B, which are obtained from the system of equations as follows;

A·X = B
The system of equations is presented as follows;

3·x + 4·y = 18

4·x - y = 5

From the above system of equations, we have:

[tex]The \ coefficient \ matrix, \ A = \begin{bmatrix} 3&4 \\ 4& -1 \end{bmatrix}[/tex]

[tex]The \ variable \ matrix, \ X = \begin{bmatrix} x \\ y \end{bmatrix}[/tex]

[tex]The \ constant \ matrix, \ B = \begin{bmatrix} 18 \\ 5 \end{bmatrix}[/tex]

From the equation, A·X = B, we have;

[tex]\therefore X = \dfrac{B}{A} = A^{-1} \times B[/tex]

Where: A⁻¹ is the inverse matrix of A, which is found as follows;

[tex]If\ A = \begin{bmatrix} a&b \\ c&d \end{bmatrix}[/tex]

[tex]Then, \ A^{-1} = \dfrac{1}{a\cdot d-b\cdot c} \cdot \begin{bmatrix} d& -b \\ -c& a \end{bmatrix}[/tex]

Which gives the value of A⁻¹ obtained from the coefficient matrix, A = [tex]\begin{bmatrix} 3&4 \\ 4& -1 \end{bmatrix}[/tex] as follows;

[tex]A^{-1} = \begin{bmatrix} 3 & 4 \\ 4 & - 1 \end{bmatrix}^{ - 1} = \dfrac{1}{(3 \times - 1) - (4 \times 4)} \times \begin{bmatrix} - 1 & - 4 \\ - 4 & 3 \end{bmatrix}[/tex]

[tex]A^{-1} = \dfrac{1}{(3 \times - 1) - (4 \times 4)} \times \begin{bmatrix} - 1 & - 4 \\ - 4 & 3 \end{bmatrix} = \begin{bmatrix} \dfrac{ - 1}{ - 19} & \dfrac{ - 4}{ - 19} \\\\ \dfrac{ - 4}{ - 19} & \dfrac{3}{ - 19} \end{bmatrix}[/tex]

The variable matrix, [tex]X = A^{-1} \times B[/tex], which gives the value of the variables in the solution is therefore;

[tex]X = \begin{bmatrix} x \\ y \end{bmatrix} = \begin{bmatrix} \dfrac{ - 1}{ - 19} &\dfrac{ - 4}{ - 19} \\ \\\dfrac{ - 4}{ - 19} &\dfrac{3}{ - 19} \end{bmatrix} \times \begin{bmatrix} 18 \\ 5 \end{bmatrix} = \begin{bmatrix} 2 \\ 3 \end{bmatrix}[/tex]

[tex]\begin{bmatrix} x \\ y \end{bmatrix} = \begin{bmatrix} 2 \\ 3 \end{bmatrix}[/tex]

The hands of a clock show 11:20. Express the obtuse angle formed by the hour and minute hands in radian measure.

Answers

ANSWER

[tex]2.44\text{ }rad[/tex]

EXPLANATION

First, let us make a sketch of the clock:

We have that for a minute hand:

[tex]1\text{ }min=6\degree[/tex]

For hour hand:

[tex]1\text{ }min=0.5\degree[/tex]

The hour and minute hand have their origin at 12.

At 11:20, the minute hand had moved 20 mins. This means that:

[tex]20\text{ }min=20*6=120\degree[/tex]

The hour hand had moved at 11 (and 20 mins more), which means:

[tex]\begin{gathered} 11*60\text{ }min+20\text{ }min \\ \Rightarrow660\text{ }min+20\text{ }min \\ 680\text{ }min \end{gathered}[/tex]

Hence, in 680 mins:

[tex]\begin{gathered} 680*0.5 \\ \Rightarrow340\degree \end{gathered}[/tex]

Therefore, the angle formed between 11 and 12 at 11:20 is:

[tex]\begin{gathered} 360-340 \\ \Rightarrow20\degree \end{gathered}[/tex]

Hence, the angle formed at 11:20 is:

[tex]\begin{gathered} 120\degree+20\degree \\ 140\degree \end{gathered}[/tex]

Now, let us convert to radians:

[tex]\begin{gathered} 1\degree=\frac{\pi}{180}rad \\ 140\degree=140*\frac{\pi}{180}=2.44\text{ }rad \end{gathered}[/tex]

That is the obtuse angle formed in radians.

A study found that 36% of the assisted reproductive technology (ART) cycles resulted in pregnancies. Twenty-six percent of the ART pregnancies resulted in multiple births.

(b) Find the probability that a randomly selected ART cycle that resulted in a pregnancy did not produce a multiple birth.(c) Would it be unusual for a randomly selected ART cycle to result in a pregnancy and produce a multiple birth?

Answers

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data:

assisted reproductive technology (ART) cycles:

pregnancies = 36%

pregnancies resulted in multiple births = 26%

Step 02:

a.

p (pregnancies) = 36% = 36/100 = 0.36

pregnancies resulted in multiple births = 26% = 26/100 = 0.26

p(pregnancies resulted in multiple births) = 0.36*0.26 = 0.0936

b.

p (pregnancy did not produce a multiple birth) = 1 - 0.0936 = 0.9064

c.

Indeed, the probability of multiple pregnancies is low 9.36%.

That is the full solution.

Pete Corporation produces bags of peanuts. Its fixed cost is $18,200. Each bag sells for $3.43 with a unit cost of $1.83. What is Pete’s breakeven point?

Answers

Let's call x to the bags of peanuts. One bag has a variable cost of $1.83, then the variable cost of x bags is 1.83x dollars.

The total cost of production for the corporation is obtained by adding fixed and variable costs. In this case, the total cost is 18,200 + 1.83x dollars.

The revenue for the corporation of 1 bag is $3.43, then of x bags is 3.43x dollars.

When the revenue and the total cost are equal, the breakeven point is reached, in this case:

18,200 + 1.83x = 3.43x

18,200 = 3.43x - 1.83x

18,200 = 1.6x

18,200/1.6 = x

11375 = x

The cost of production of 11375 bags is:

Total Cost = 18,200 + 1.83*11375

Total Cost = 18,200 + 20816.25

Total Cost = 39016.25

Pete’s breakeven point is (11375, 39016.25), or, 11375 bags and $39,016.25

Answers

We have the following triangles:

And we need to determine if they are similar by identifying the similarity statement.

To determine that similarity statement, we can proceed as follows:

1. Check the measures of the internal angles of the triangles. We need to remember that the sum of the internal angles of a triangle is 180 degrees. Then we have:

2. We can see that to find the angles in the first triangle, EFG, and in the second triangle, JKL, we have that the sum of the three angles must be 180 degrees, and we obtained the other angles as follows:

[tex]\begin{gathered} \text{ Triangle EFG}\rightarrow50+70+x=180 \\ \\ x=180-(50+70)=180-120=60 \\ \\ \text{ Triangle JKL}\rightarrow50+60+y=180 \\ \\ y=180-(50+60)=180-110=70 \end{gathered}[/tex]

3. Then we can redraw the triangles as follows:

4. Now, since we can see that, at least, two of the angles of the triangles are congruent (then the third one is also congruent, that is, has the same measure), we also have that to prove that if two triangles are similar it is sufficient that two of the corresponding angles of one triangle are congruent to the two corresponding angles of the other triangle, and this is known as the Angle-Angle method for proving similar triangles, then we can conclude that:

Triangle EFG is similar to triangle JKL by the Angle-Angle method.

Therefore, in summary, we have that:

Triangle EFG is similar to Triangle JKL by Angle-Angle similarity

The word "ratio" is where the word "rational" first appeared. Rational numbers are therefore closely tied to the idea of fractions, which stand for ratios. In other terms, a number is a rational number if it can be written as a fraction in which the numerator and denominator are both integers.

Given:

We have to find the rational number between -0.45 and -0.46

Now, make both decimal into fraction

-0.45 and -0.46

-45/100 and -46/100

Now, multiply 2

-45/100 x 2/2 and -46/100 x 2/2

-90/100 and - 92/100

Hence, the rational number is -91/100 or -0.91.

A circle has a center point at the coordinates P(3,0) with a diameter line RT where R has the coordinates (-47,25).What is the Coordinates Of T

Answers

Given: A circle has a center point at the coordinates P(3,0) with a diameter line RT where R has the coordinates (-47,25).

Required: To determine the coordinates of T.

Explanation: The given circle is-

Let the coordinates of T be (x,y). Then the center of a circle is divided by the diameter in the ratio of 1:1. The section formula for a point (x,y) dividing a line segment in the ratio of 1:1 is-

[tex]\begin{gathered} x=\frac{(x_1+x_2)}{2}, \\ y=\frac{(y_1+y_2)}{2} \end{gathered}[/tex]

Hence, for the given line RT, point P divided RT in 1:1. Thus-

[tex]\begin{gathered} 3=\frac{-47+x}{2}, \\ 0=\frac{25+y}{2} \end{gathered}[/tex]

Further solving for x and y as-

[tex]\begin{gathered} x=6+47 \\ \Rightarrow x=53 \\ and\text{ }y=-25 \end{gathered}[/tex]

Final Answer: The coordinates of T are (53,-25).
