Please help me!! I have no idea how to solve this. I have two more like this and if you answer this one correct I will ask you if you could solve the other two and give you 15 for each question.

Answer:

Yes, they are equivalent.

Step-by-step explanation:

Both of the expressions equal to 77. 42+35 is easy, just add to get 77. To solve 7(6+5) remember PEMDAS which tells you to do parentheses first. So add 6+5, which is 11, then multiply by 7. 11*7 is 77, therefore the expressions are equivalent.

Answer:

  x < -2  or  3 < x

Step-by-step explanation:

6x -4 > 14

  6x > 18 . . . . add 4

  x > 3 . . . . . . divide by 6

3x +10 < 4

  3x < -6 . . . . subtract 10

  x < -2 . . . . . divide by 3

The solution is the union of disjoint sets:

  x < -2  or  x > 3

Step-by-step explanation:

(-3+1)/2 = -2/2 = -1

(8+2)/2 = 10/2 = 5

(-1, 5)

Answer:

[tex]\boxed {(-1, 5)}[/tex]

Step-by-step explanation:

Use the Midpoint Point Formula to determine the midpoint of two given points:

[tex](\frac{x_{1} + x_{2}}{2}, \frac{y_{1} + y_{2}}{2})[/tex]

First point: [tex](x_{1}, y_{1})[/tex]

Second point: [tex](x_{2}, y_{2})[/tex]

-Substitute the given points:

First point: [tex](-3, 8)[/tex]

Second point: [tex](1, 2)[/tex]

[tex](\frac{-3 + 1}{2}, \frac{2 + 8}{2})[/tex]

-Solve the equation:

[tex](\frac{-3 + 1}{2}, \frac{2 + 8}{2})[/tex]

[tex](\frac{-2}{2}, \frac{10}{2})[/tex]

[tex]\boxed {(-1, 5)}[/tex]

Thus, the midpoint is [tex](-1, 5)[/tex].

Answer:5

Step-by-step explanation:When we divide two fractions, such as 5/7 ÷ 1/7, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other.

Answer:

B

Step-by-step explanation:

Answer:

The correct option is C.

Step-by-step explanation:

About 59% of the 45,000 people responded as "Yes" to the question, "Do you regularly read nonfiction novels?”

The sample size is, n = 45,000.

The sample proportion is, p = 0.59.

The sample selected is a voluntary sample, i.e. the individuals provided their responses voluntarily. So, the sample is not a true representative of the population. Though the results tell us little about the population of all adults because of the large sample size.

Thus, the correct option is C.

Step-by-step explanation:

rise over run

Answer: 50

Step-by-step explanation:

Let the number of pizza made last week be represented by y.

From the question, we can form it into:

24% of y = 12

24/100 × y = 12

0.24 × y = 12

0.24y = 12

y = 12/0.24

y = 50

50 pizza were made last week.

5-10: Identify which line from the graph the following right triangles could lie on.

Answer:

$7462 to the nearest dollar.

Step-by-step explanation:

10000 = P(1 + 0.05)^6   where P is the initial investment.

10000 = P * 1.05^6

Taking logs:

log 10000 = log P + 6  log 1.05

log P = log 10000 - 6 log 1.05

log P = 4 - 0.127136 = 3.872864

P = 7462

Answer:

C,-3

Step-by-step explanation:

take y2-y1/x2-x1

6+3/-3=Neg 3

Answer:

C. -3

Step-by-step explanation:

You can do this using two different methods.

First, slope is written rise over run, or y over x. We can find two points and count how much we need to rise and run. The graph already includes the points (2,-3) and (-1, 6), which we will use. If you carefully look at the graph, you can see that if you start from the point (2,-3), you can rise 9 and run -3 to get to the point (-1, 6), which brings me to the next step. As I stated in the beginning, slope is written rise over run. Therefore, the slope is 9/-3, which simplifies to -3, answer choice C.

Another way you can do this is subtracting the y's and subtracting the x's in the same order. The y's go over the x's, and is basically written as a fraction. For this method, we still need two points. We will use the same points as above and listed on the graph, points (2,-3) and (-1, 6). The y's are -3 and 6, and the x's are 2 and -1. Now, subtract.

-3-6  =-9=-3

2-(-1)= 3

As you can tell, both methods of solving for slope worked, and the answer is choice C.

I hope this helps!! Have a great day, and thanks for the points (^人^)

Answer:

1:4.5 or 2:9 if you want it a whole number.

Step-by-step explanation:

81/18 = 4.5If your trying to get it to a whole number the answer would be 2:9 because 18/9 = 2 and 81/9 = 9 so 1:4.5 or 2:9.

Answer: Perimeter = 22*sqrt(2)

Area = 60.5 inches

Step-by-step explanation:

Simple a  square has 4 equal sides.

It contains (by definition) 1 right angle but since we are not including and statement about parallel sides, it needs 4 right angles.

Answer:

4*[tex]\sqrt{60.5}[/tex] is peremiter and 60.5 is area

Step-by-step explanation:

11x11=121/2=60.5

[tex]\sqrt{60.5}[/tex]=one side of square

4*[tex]\sqrt{60.5}[/tex]=peremiter

60.5=area

Answer:

625 minutes

Step-by-step explanation:

Given that:

Time taken to tie 4 ribbons = 10 minutes

Number of ribbons to be tied = 250

To find:

Time taken to tie 250 ribbons.

Solution:

First of all, we need to find the time taken to tie one ribbon.

And then we can multiply it with 250 to find the time taken to tie all the 250 ribbons.

For finding the time to tie one ribbon, we need to divide the time taken to tie 4 ribbons with 4.

Time taken to tie 1 ribbon = [tex]\frac{10}{4} = 2.5[/tex] minutes

Time taken to tie 250 ribbons = 2.5 [tex]\times[/tex] 250 = 625 minutes

Answer:

[45]

Is the answer................

Answer:

The internal angles are 78°, 72°, 30°, and the external angle is 150°

Step-by-step explanation:

In a triangle, the measure of an external angle at one vertex equals the sum of the measures of the opposite internal angles to this vertex

In the given figure

∵ The angle of measure (4x + 22) is an exterior angle

∵ The angles of measures (3x - 18) and (2x + 8) are the opposite

   interior angles

→ By using the rule above

∴ (3x - 18) + (2x + 8) = (4x + 22)

→ Add the like terms in the left side

∵ (3x + 2x) + (-18 + 8) = 4x + 22

∴ 5x + (-10) = 4x + 22

→ Remember (+)(-) = (-)

∴ 5x - 10 = 4x + 22

→ Add 10 to both sides

∵ 5x - 10 + 10 = 4x + 22 + 10

∴ 5x = 4x + 32

→ Subtract 4x from both sides

∵ 5x - 4x = 4x - 4x + 32

∴ x = 32

→ Substitute the value of x in the external and internal angles to find them

∵ The external angle = 4(32) + 22 = 128 + 22

∴ The external angle = 150°

∵ One of the internal angle = 3(32) - 18 = 96 - 18

∴ One of the internal angle = 78°

∵ Other internal angle = 2(32) + 8 = 64 + 8

∴ Other internal angle = 72°

→ The sum of the measure of the internal angles of a Δ is 180°

∵ The third internal angle of the triangle = 180° - 78° - 72°

∴ The third internal angle of the triangle = 30°

∴ The internal angles are 78°, 72°, 30°, and the external angle is 150°

Answer:

2.98×10^-6 hrs

Step-by-step explanation:

Speed = Distance/Time

Time = Distance/speed

Given

Distance = 17in

Speed= 90mph

Convert inches to miles

1in = 1.578 × 10-5 mile

17in = 17(1.578 × 10-5) mile

17in = 26.826×10^-5miles

Get the time

Time =26.826×10^-5/90

Time = 0.298×10^-5

Time = 2.98×10^-6 hrs

Reflect the intermediate image.

Multiply the vertices of polygon ABCD by One-half.

Answer:

-6

Step-by-step explanation:

5p - 14 = 8p + 4

Subtract 8p from both sides.

-3p - 14 = 4

Add 14 to both sides.

-3p = 18

Divide both sides by -3.

p = -6

Answer: -6

9514 1404 393

Answer:

Step-by-step explanation:

Depth of snowfall is usually measured above some base. The greater the depth, the higher the surface is above the base.

When the depth decreases, as by melting, the change in depth is negative. That is, the difference between the new depth and the old one is negative. A 12" depth experiencing a change of -1 inch becomes an 11" depth.

If the question is about how much the depth decreased, the decrease is given as a positive value. A 12" depth decreased by (+)1 inch becomes an 11" depth.

The sign of the number of interest depends on what question it is answering.
