Jeff bought 4 oranges and 7 apples for a total of $4.88. Gene bought 12 oranges and 8 apples for a total of $7.88. What is the cost of each orange and each apple?

Answers

Answer 1
4x+7y=4.88 -> mult by -3 -> -12x-21y=-14.64
12x+8y=7.88
-12x-21y=-14.64
Add the two above equations together, the y will be left:
-13y=-6.76
y=0.52 —> cost of each apple (plug back into one of original equations, I chose 4x+7y=4.88:
4x+7(0.52)=4.88
Solve for x.
x=0.31 —> cost of each orange

Find the value of x and y of the equilateral triangle

Answers

Answer:

x = 12

y = 30

Step-by-step explanation:

We know:

All sides of equilateral triangle are equal:

= > 3 x + 8 = 4 x - 4

= > 8 + 4 = 4 x - 3 x

= > x = 12

Also, we know all angles of equilateral triangle is 60. And their sum is 180.

= > 2 y = 60

= > y = 30

Find the missing side of this right triangle.

Answers

You can solve right angle triangles using the pythagorean theorem, in which a^2 + b^2 = c^2, where c is the largest side.
Rearrange this to c^2 - b^2 = a^2
giving you 5^2 - 3^2 = A^2
in which 16 = a^2
and to solve for just a, square root both sides to give you a final answer of a = 4

The floor of a rectangular cage has a length 4 feet greater than its width, w. James
will increase both dimensions of the floor by 2 feet. Which equation represents the
new area, N, of the floor of the cage?

Answers

Answer:

x² + 8x + 12

Step-by-step explanation:

Area of a rectangle = length × width

Original dimensions:

Width = x

Length = x + 4

James will increase both dimensions of the floor by 2 feet

New dimensions:

Width = x + 2

Length = x + 4 + 2

= x + 6

Area of the new rectangle = length × width

= (x + 2) × (x + 6)

= x² + 6x + 2x + 12

= x² + 8x + 12

Equation which represents the

new area, N, of the floor of the cage = x² + 8x + 12

Answer:

f(x) = -½x + 16

Step-by-step explanation:

Using two points in the line, (0, 16) and (4, 14), we can write an equation for the linear function in the slope-intercept form, f(x) = mx + b, by finding the slope (m) and the y-intercept (b), then substituting each of the value into f(x) = mx + b.

✔️Slope (m) = change in y/change in x

Using, (0, 16) and (4, 14),

Slope (m) = (14 - 16)/(4 - 0) = -2/4

m = -½

✔️y-intercept (b) would be the value of y when x = 0, or the point at which the y-axis is intercepted by the line.

Thus,

When x = 0, y = 16

Therefore,

b = 16

✅Write the equation of the function by substituting m = -½ and b = 16 into f(x) = mx + b

Thus:

f(x) = -½x + 16

16) Jenna is responsible for changing the broken light bulb in a streetlamp. The streetlamp is 14 feet high. Jenna places the base of her ladder 3 feet from the base of the streetlamp. Jenna can extend the ladder from 10 feet to 14 feet. How long must her ladder be to reach the top of the streetlamp? Will her ladder work?​

Answers

Use the Pythagorean theorem:

Height is 14, base is 3, so we can calculate the length required.

Length = sqrt(14^2 + 3^2)

Length = sqrt( 196 + 9)

Length = sqrt(205)

Length = 14.32 feet.

Question 4
In order to ensure that the roof consists of right angles, an architect measures the diagonal to create a triangle. If the dimensions of the
triangle are 9.5 feet, 16 feet, and 18.5 feet, is the triangle a right triangle?

Answers

Answer:I have a question

Step-by-step explanation:

About that question is it a right triangle or no

The triangles with side lengths 9.5 feet , 16 feet and 18.5 feet is an acute triangle

What is a Triangle?

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the height of the triangle is AB = 16 feet

The base of the triangle is BC = 9.5 feet

The hypotenuse of the triangle is AC = 18.5 feet

And , for a triangle , if a² + b² > c² , it is an acute triangle

Substituting the values in the equation , we get

( 9.5 )² + ( 16 )² > ( 18.5 )²

90.25 + 256 > 342.25

346.25 > 342.25

Hence , the triangle is an acute triangle
