he measure of angle AFB = 78°

Answers

It’s angle AFE because its the one in the same line as AFB and since the line is 180 degrees that means they add up to 180
Angle AFE is supplementary to angle AFB because they are both along the line with points EFB. When two angles are along a straight line, they equal 180 degrees. This is also what the definition of supplementary is.

The Empire State Building is just over 1,450 feet tall. In anticipation of visiting this
landmark on your vacation, you create a model of it using blocks.

a) Suppose you are making a model where one block represents 2 feet. About how
many blocks tall is your model of the Empire State Building? What is the scale
factor? (2 points)

b) Suppose you are making a model where one block represents 5 feet. About how
many blocks tall is your model of the Empire State Building? What is the scale
factor? (2 points)

c) Look at the scale factor from parts a and b. Do they represent a reduction or an enlargement of the Empire State Building? How do you know? (2 points)

d) Use your knowledge of scale drawings and image sizes to fill in the missing
information in the table. (3 points)

Answers

A) your model would be 725 blocks tall because 1,450/2=725
B) your model would be 290 blocks tall because 1,450/5=290.
C)reduction of the Empire State Building because you are building a model that takes blocks representative of a larger unit than what it signifies
D)don’t have the table to fill in

Model  requiring  525 block and 290 blocks

What is scale factor ?

Scale Factor is used to scale shapes in different dimensions. In geometry, we learn about different geometrical shapes which both in two-dimension and three-dimension. The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii.

a) You have two given data available here: the actual height of the Empire State Building measuring 1,450 feet, and the height of the block measuring 2 feet. To find how many blocks stacked together would make up 1,450 feet, just divide 1,450 by 2.

Number of blocks=1,450 feet * (1 block/2 feet)

Number of blocks = 725 blocks

Therefore, you would use a model requiring 725 blocks.

The scale factor for the model is 1 block per two feet.

b) You have two given data available here: the actual height of the Empire State Building measuring 1,450 feet, and the height of the block measuring 5 feet. To find how many blocks stacked together would make up 1,450 feet, just divide 1,450 by 5.

Number of blocks=1,450 feet * (1 block/5 feet)

Number of blocks = 290 blocks

Therefore, you would use a model requiring 290 blocks.

The scale factor for the model is 1 block per five  feet.

I did it for you but here is an explanation.

First, categorize each fraction. So like this. Just write it out.

1/2,1/2,1/8,1/8,3/8,3/16,5/16,5/16,5/16,5,16

Then, plot the points according to where each number goes.

Answer:

For 1/2 it will go up 2 times

For 5/16 this will go three times upwards.

For 1/8 mark that two times upwards.

3/8 will only go up once.

3/16 will also go up once.

It should kind of look like a bargraph if you know what I mean.

HELP HELP ! The figure below has a point marked with a large dot. First, translate the figure 6 units to the right. Then, give the coordinates of the marked point in the original figure and the final figure.​

Answers

Answer:

original (7,-4)

Final (7,2)

Step-by-step explanation:

I'm not 100% positive considering I haven't done this type of work in a long time.

The new coordinates of the marked point will be - P'(2, 7).

We have a figure plotted on X - Y coordinate plane.

We have give the coordinates of the marked point in the original figure when we translate the figure 6 units to the right.

Define Translation of Points on a Coordinate Plane.

The translation of a point in a coordinate plane is the movement of point along the X and Y axis (Right, left, upwards or downward) on intersection of which this point lies.

(x, y) → (x + m, y + n)

According to the question, we have -

The coordinates of the Marked point → P (-4, 7).

When this figure is translated 6 units to the right, then the new coordinates of the marked point will be -

P'( - 4 + 6, 7) = P'(2, 7)

Hence, the new coordinates of the marked point will be - P'(2, 7)

A box of oranges weighs 4 kg. If one orange weighs 80 g, how many oranges are in the boxes?

Answers

Answer:

There are 50 oranges in the box.

Step-by-step explanation:

Weight of box = 4 kg = 4000 g

Weight of 1 orange = 80 g

No. of oranges in the box = ?

No. of oranges in the box = Weight of the box / Weight of 1 orange

No. of oranges in the box = 4000 / 80 = 50 oranges.

Answer: 50 oranges .

there are 1000 grams in a kilogram .

Each oranges weight 80 g and there are 4 kg .

4 kg multiplied by 1000 equals to 4000 g .

4000 divided by 80 equals to 50 .

Which means there are 50 oranges in the boxes .

The histogram below shows information about the hours students spent exercising in a week:

A histogram is titled Weekly Exercise, the horizontal axis is labeled Hours of Exercise, and the vertical axis is labeled Students. The range on the horizontal axis is 0 to 4, 5 to 9, and 10 to 14. The values on the vertical axis are from 0 to 10 at intervals of 1. The first bin goes to 4, the second bin to 9, the third bin to 5.

Which information is provided in the histogram?

A:The number of students who exercised 4 hours or more
B: The number of students who exercised 9 hours or fewer
C:The mean hours of exercise
D:The median hours of exercise

Answers

Answer: A

Step-by-step explanation: with my calculation, and the information you have give i have to say it is A.

C and D are somewhat correct. We may be able to estimate the mean and median hours from the histogram.

A seems to the closest answer, but not exactly correct.

Step-by-step explanation:

It seems that none of the descriptions is exactly right. The first bin is 0 to 4 hours, so the "4 hours or more is not accurate. The third bin is 10 to 14 hours, so B is wrong.
