===================================================

Explanations:

Problem 1

We have B = 62+32 = 94 people who wear a belt. Of this total, A = 62 belt wearers also have a watch. So A/B = 62/94 = 0.6596 = 65.96% = 66% of the belt wearers have a watch. This value is approximate.

-------------------------------

Problem 2

In the previous problem we found that roughly 66% of the belt wearers have a watch. This must mean about 100% - 66% = 34% of the belt wearers do not have a watch.

-------------------------------

Problem 3

The question is "Among left handers, what proportion has neat handwriting?" which means we're effectively only concerned with the first row that says "left-handed". In this row, there are 5 who write neat, and 10 who do not. We have B = 5+10 = 15 people who are left-handed. We'll divide everything in this row by this value of B.

So for A = 5, it turns into the approximate proportion A/B = 5/15 = 0.33 meaning that about 33% of the left-handers have neat handwriting.

For the other value in this row, A = 10 turns into A/B = 10/15 = 0.67 = meaning that about 67% of the left-handers have messy hand writing.

You'll do the same thing for row 2, but you'll divide everything by B = 65 (because there are 34+31 = 65 right-handed people total).

The filled out table is shown below.

-------------------------------

Problem 4

Let's say we ignore the percentage signs. Adding the values across the first row gets us B = 86+14 = 100 people who passed the quiz. Of that, A = 86 people who passed also studied as shown in the top left corner.

We can then see that A/B = 86/100 = 86% of the people who passed the quiz also studied. Notice the phrasing here. It's not the other way around. We would not say "86% of the people who studied passed the quiz". Your teacher has the order swapped unfortunately. If choice C said "86% of the people who passed the quiz studied for the test", then it would be fully correct. However, I think that's what they were going for and made a typo.

If we did state that "86% of the people who studied passed the quiz", then we'd be considering the first column instead of the first row. However, note how the percentages in the first column do not add to 100%.

Answer:

700ft³

Step-by-step explanation:

We have to multiply 20 x 7 x 10 = 1400 and we have to divide by 2 because the volume of a triangle is * L x W x H /2* so 1400/2= 700

Answer: 18

Step-by-step explanation:

Find the scale factor: 144/36= 4. But scale factor of area is r^2=4=> r= 2

Hypotenuse of small triangle is:

36/x=2 => x=18

Answer:

Thus, the total number of boards required is 2148.

Step-by-step explanation:

Each section of fence contains 12 boards

So, the number of boards required for 179 section of fence is

= 179 x 12 = 2148 boards

In triangle ABC angle c = 180-78-40 = 62 degrees

For the triangles to be congruent angle z must equal angle C

Solve for x:

2x + 8 = 62

Subtract 8 from both sides:

2x = 54

Divide both sides by 2:

X = 27

Now we k ow x has to equal 27 to be concurrent so we can answer the 3 questions.

A. False

B. True

C. True

Givens:

Eq. 1 )  x + y = 5

Eq 2 )  x = 1 + y  

plug x into Eq 1 from Eq 2

(1+y) + y = 5

algebra them out

2y = 4

y = 2

then

x + 2 = 5

x = 3

84.82275

Step-by-step explanation:

The formula for Area of a circle is

[tex]A=\pi r^{2} \\A=\pi 6^{2} \\A=113.097[/tex]

That would be for the entire circle, now divide that number by .75 to get 3/4 of the circle.

A) 2631.20

Step-by-step explanation:

8% of 32,890 is 2631.2

Answer:

d. (-4,2)

Step-by-step explanation:

Here, Y = 1/2X + 4

Or, –5/4X – 3 = 1/2X + 4 (From equation 1 and 2)

Or, –5/4X = 1/2X + 4 + 3

Or, –5/4X = 1/2X + 7

Or, 1/2X + 7 = –5/4X

Or, 7 = –5/4 X – 1/2 X

Or, –5/4X – 2/4 X = 7

Or, –7/4 X = 7

Or, –7 X = 7 × 4

Or, –7X = 28

Or, X = 28/–7

Or, X = – 4

Here, in the fourth option, we can see that X= –4, Hence Option D— (-4,2) Is correct.

The company needs to sell 8 units in order for the net income to equal $0

The net income function is given as:

[tex]f(x) = 9x^2 - 54x - 144[/tex]

When the net income is 0, then f(x)  = 0.

So, we have:

[tex]9x^2 - 54x - 144 = 0[/tex]

Divide through by 9

[tex]x^2 - 6x - 16 = 0[/tex]

Expand the above equation

[tex]x^2 +2x- 8x - 16 = 0[/tex]

Factorize the above equation

[tex]x(x +2)- 8(x + 2) = 0[/tex]

Factor out x + 2 in the above equation

[tex](x - 8)(x + 2) = 0[/tex]

Split and solve for x

[tex]x = 8[/tex] or [tex]x =-2[/tex]

The units of product cannot be negative.

So, the value of x is [tex]x = 8[/tex]

Hence, the company needs to sell 8 units

Answer:

[tex]3632 {ft}^{2} [/tex]

Step-by-step explanation:

To find the area of a circle, you use the formula:

[tex]\pi \: {r}^{2} [/tex]

In your problem the radius is 34, so when you square that, multiply is by pi, and round it to the nearest whole number, the answer is 3,632.

Answer:

area = 250.04 km^2

Step-by-step explanation:

In the image, we have the next figures.

One quart of a circle, with radius R = 12km

A large rectangle, with length L = 13km and width = 9 km

(to find the width of this rectangle, look at the bottom, we have a part of 5km, and then we have the small rectangle with a width of 4km, then 4km + 5km = 9km)

And finally, a smaller rectangle with length L = 5km and width W = 4km

Now, the general rules for each figure are:

The area of a circle of radius R, is

A = pi*R^2

with pi = 3.14

Here we have the fourth part of a circle with a radius R = 12km

Then the area of that part is:

area = (1/4)*3.14*(12km)^2 = 113.04 km^2

And the area of a rectangle of length L and width W is:

A = W*L

Then, the area of the larger rectangle is:

A' = 9km*13km = 117 km^2

And the area of the smaller rectangle is:

A'' = 4km*5km = 20km^2

The complete area of the figure is:

area = A + A' + A'' =  113.04 km^2 +  117 km^2 + 20km^2 = 250.04 km^2
