is the new balance?

Answer:

x>-4, x<=27.5

Step-by-step explanation:

First mark your digits on the number line. For question 9, it seems that x>-4, so mark that on your number line and draw an empty circle with an arrow pointing right.

For 13 multiply both sides by 5/4, and your answer is 27.5>=w. Mark it down with a filled in circle and an arrow going to the left.

Azimuth is the angle measured in a horizontal circle around your horizon.

In this question,

The horizon angle is the maximum upwind slope in wind exposure / sheltering studies.

A line from the center of the Earth which continues through the observer's body and the top of the observer's head. This line is zenith.

Azimuth is the coordinate direction that runs parallel to the horizon and rotates clockwise from north (0 degrees) to east (90 degrees) to south (180 degrees) to west (270 degrees) back to north (360 degrees).

The meridian is an imaginary North-South line running through the zenith.

Therefore, Azimuth is the angle measured in a horizontal circle around your horizon.

Mean height of the students in the class = 65.7 inches

The mean height of all 12 students in the class is 66.0 inches.

So the Total height of 12 students in the class = 66 × 12

                                                                              = 792 inches

As Danielle's height = 62.1 inches

So the total height of 13 students = 792 + 62.1

                                                        = 854.1 inches

Mean of all 13 students in the class = 854.1 / 13

Hello,

3x²y² + 4xy - 2x²y² - 6xy = x²y² -2xy

Answer:

the answer is x=17,y=14/3

Answer:

x=4 y=5

Step-by-step explanation:

8x-9y=-13

2x-3y=-7

Solve for y:

Multiply the bottom by 4 to have the x's equal each other and cancel out:

8x-9y=-13

8x-12y=-28

Then subtract:

0x+3y=15

y=15/3 -> y=5

Solve for x:

Multiply the bottom by 3 to have the y's equal each other and cancel out:

8x-9y=-13

6x-9y=-21

Then subtract:

2x=8

x=4

Option a, 2x + 1, 6 and 13, 7 and 15.

Here, we are given input-output table as shown in the figure.

To find the equation for this table let us look at each option one by one-

a. 2x + 1

Here if we take input x = 2

output = 2(2) + 1

= 5

If x = 3

output = 7

and if we check for other values also, 2x + 1 will satisfy.

Thus, 2x + 1 is the correct equation.

we can check the points as well-

if x = 6

output = 2(6) + 1 = 13

and if x = 7

output = 2(7) + 1

= 15

Since, we've found the correct answer in option a, we do not need to check the other options.

Thus, option a is the correct answer.

These periods are named as ones, thousands, lakhs, and so on. The one's period consists of the first three digits of the large number, starting from the right.

Everyone learns how to count numbers at a very young age starting from a single digit up to seven digits. This is done with the help of the place value system.

While writing large numbers, we always keep the place value system in mind to ensure that it is written correctly. According to the Indian place-value system, when a number is written in the standard form, each group of digits separated by a comma is called a period.

These periods are named as ones, thousands, lakhs, and so on. The one's period consists of the first three digits of the large number, starting from the right. The thousands period consists of the next two digits. The lakhs period consists of the next two digits and it continues.

Some other large numbers are read and written as follows:

1,000,000,000 = one billion

1,000,000,000,000 = one thousand billion

Equation: [tex]\sf 3x + x + 14 = 90[/tex]

m∠1 = 57°

m∠2 = 33°

Explanation:

A right angle triangle has 90° angle measure.

Here:

m∠1 + m∠2 = 90°

(a)

Substitute given values:

(3x) + (x + 14) = 90

simplify

4x = 90 - 14

evaluate

4x = 76

divide both sides by 4

x = 19

(b)

m∠1 = 3x = 3(19) = 57°

m∠2 = x + 14 = 19 + 14 = 33°

Answer:

[tex]\textsf{(a)} \quad (3x)^{\circ}+(x+14)^{\circ}=90^{\circ}[/tex]

[tex]\textsf{(b)} \quad m \angle 1=\boxed{57}\:^{\circ}[/tex]

       [tex]m \angle 2=\boxed{33}\:^{\circ}[/tex]

Step-by-step explanation:

From inspection of the given diagram:

A right angle is 90° and is represented by the ∟ symbol.

To find x, equal the sum of the angles to 90° and solve for x:

[tex]\implies m \angle 1+m\angle2=90^{\circ}[/tex]

[tex]\implies (3x)^{\circ}+(x+14)^{\circ}=90^{\circ}[/tex]

[tex]\implies 3x+x+14=90[/tex]

[tex]\implies 4x+14=90[/tex]

[tex]\implies 4x+14-14=90-14[/tex]

[tex]\implies 4x=76[/tex]

[tex]\implies 4x \div 4=76 \div 4[/tex]

[tex]\implies x=19[/tex]

To find the degree measure of each angle, substitute the found value of x into the expression for each angle.

[tex]\implies m \angle 1=(3 \cdot 19)^{\circ}=57^{\circ}[/tex]

[tex]\implies m \angle 2=(19+14)^{\circ}=33^{\circ}[/tex]

By substituting the value of x as 17 in the function R (x) = 2 x + 3.5, we get the value of R ( 17 ) as 37.5.

We are given a function:

R (x) = 2 x + 3.5

where x represents the number of feet the tide moves x minutes after 4 pm.

Now, we are asked to find R (17)

For this, we need to substitute the value of x as 17 that is we need to put x = 17 in the function that is given to us.

R ( x = 17 ) = 2 ( 17 ) + 3.5

R ( 17 ) = 34 + 3.5

R ( 17 ) =37.5

Therefore, by substituting the value of x as 17, we get the value of R ( 17 ) as 37.5.

The required weight after 43  hours is 72. 96mg

From the information given, we have that;

A Scientist begins with 180 milligrams of a radioactive substance

Let us take Po = 180 milligrams

Using the expression;

[tex]P(t) = Poe^k^t[/tex]

Substituting the values of t = 33, P = 90mg and Po = 180

90 = 180e^33t

[tex]e^3^3^t = \frac{1}{2}[/tex]

Take the log of both sides

[tex]33ln(e^k) = ln (\frac{1}{2} )[/tex]

[tex]k = -\frac{ln 2}{33}[/tex]

k = - 0. 0210

The equation becomes: P(t) = 150e^-0.0210

Substitute t as 43

[tex]P(43) = 180e^-^0^.^0^2^1^0 ^*^4^3[/tex]

P(43) = 72. 96 mg

Hence,  72. 96 mg will remain after 43 hours.

It will take 2 hours 48 minutes for the two trains to meet.

For given question,

Two trains leave stations 560 miles apart at the same time and travel toward each other.

One train travels at 95 miles per hour while the other travels at 105 miles per hour.

This means the speed one train is 95 mph while the speed of other train is 105 mph.

Let t be the time in hours for two trains to meet.

From given scenario,

⇒ 560 = (105 + 95)t

⇒ 560 = 200 t

⇒ t = 2.8 hours

1 hour = 60 minutes

So, 0.8 hours = 48 minutes

⇒ 2.8 hours = 2 hours 48 minutes

This means, both trains meet after 2 hours 48 minutes

Step-by-step explanation:

you and your teacher mean "h" ?

this we get by using Pythagoras, because h, half of the baseline and one of the 51 m sides create a new right-angled triangle :

c² = a² + b²

c being the Hypotenuse (the side opposite of the 90° angle). a and b are the legs.

so, for that new inner triangle we have then

51² = h² + (48/2)² = h² + 24²

2601 = h² + 576

h² = 2025
