Answer:

[tex]46 \frac{7}{8} \: cubic \: feet[/tex]

Step-by-step explanation:

[tex]\boxed{volume \: of \: prism = base \: area \: \times height}[/tex]

Base area= length ×width

Let's convert all the mixed numbers into improper fraction for easier calculation.

Width

= 7½

[tex] = \frac{7(2)}{2} + \frac{1}{2} [/tex]

[tex] = \frac{14}{2} + \frac{1}{2} [/tex]

[tex] = \frac{15}{2} ft[/tex]

Height

= 1¼

[tex] = \frac{4}{4} + \frac{1}{4} [/tex]

[tex] = \frac{5}{4} ft[/tex]

Volume of prism

[tex] = 5 \times \frac{15}{2} \times \frac{5}{4} [/tex]

[tex] = \frac{375}{8} [/tex]

[tex] = 46 \frac{7}{8} \: ft {}^{3} [/tex]

Answer:

D. Completely randomized design

Step-by-step explanation:

Based on the description given about the experiment above and the manner in which the subjects were assigned to each of the treatment groups available, we can deduce that the study was conducted using a completely randomized design. The subjects weren't matched or blocked for any variable such as sex, height, age or any other variable. They were just evenly split randomly into the two available treatment levels ( those who receive the treatment and the placebo) group. With this design, all subjects have an equal chance of being in any of the two groups and the selection bias is almost totally eliminated using this sort of design as errors are being considered as arising from experimental faults.

Answer:

Hypotenuse: 6

Step-by-step explanation:

Sin45°=(BC/AC)

Sin45°=(3√2/AC

1/√2=3√2/AC

AC=3×2=6

so hypotenuse = 6

hope it helps

have a great day!!

Answer:

6

Step-by-step explanation:

here's your solution

=> sin 45° = perpendicular/hypotenuse

=> sin 45° = 1/√2

=> perpendicular = 3√2

=> 1/√2 = 3√2/hypotenuse

=> Hypotenuse = 3*√2*√2

=> Hypotenuse = 3*2

=>. Hypotenuse = 6

Answer:

c

Step-by-step explanation:

first, find the area of the rectangle thing,

A = lw

14 x 8

112

but, there is a semicircle in it so you need to subtract that from it:

A = πr^2/2

A = π(4)^2/2

A = π16/2

A = 8π

A ≈ 25.132741228718346

then subtract that area from the area of the rectangle:

112 - 25.132741228718346

86.867258771281654

or about 89.9

Answer:

61

Step-by-step explanation:

median mean the middle number (number that appears to be in the middle)

you were given a series of numbers, like in this question is quite easy because you were given five numbers. so you cancel out two from the left and two from your right the remainder is 61 and that's your median.

Answer:

  $44,935

Step-by-step explanation:

The amount due will be ...

  A = P(1 +rt) . . . . principal P at annual rate r for t years

__

3 months is 3/12 = 1/4 years, so the amount is ...

  A = $44,000(1 +0.085×1/4) = $44,935 . . . amount paid back

Answer:

d. Cos B = 9/41

Step-by-step explanation:

Recall, SOHCAHTOA.

Cos B = Adjacent length / Hypotenuse length

Adjacent length to reference angle B = 27

Hypotenuse length = 123

Cos B = 27/123 = 9/41

Answer:

this corect answer for this question

Step-by-step explanation:

[tex]f(3) = 3 \times {3}^{2} = 27 \\ f(3) = 3 \times {2}^{3} = 24[/tex]

Answer:

y = 218

Step-by-step explanation:

Mean = (Sum of all numbers)/(How many numbers present)

27 = (20 + 2y + 25 + y + 30)/27

27 = (3y + 75)/27

3y + 75 = 729

3y = 729 - 75

3y = 654

y = 218

Step-by-step explanation:

A) divide actual inches by scale:

28/7 =4 cm

B) multiply actual cm by scale:

9 x 7 = 63 inches

Answer:

x= -2

Step-by-step explanation:

2(x+3)=5x+10-x (we need to distribute first)

2x+6=4x+10   (then add like terms)

-2x=4    (now divide)

x= -2

Answer:

22% probability the student is a junior.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes:

The table says that:

There are 4 + 6 + 2 + 2 + 3 + 4 + 6 + 6 + 3 = 36 total students.

2 + 6 = 8 are juniors.

If a student is selected at random, find the probability the student is a junior.

8/36 = 0.2222 = 22.22%

Rounding to the nearest whole percent, 22% probability the student is a junior.

Answer:

27%

Answer:

r = 7.7

Step-by-step explanation:

A = πr²

60π = πr²

r² = 60π/π

r² = 60

[tex]\sqrt{r^2} =\sqrt{60}[/tex]

r = 7.746

Rounded to tenths:

Answer:

$467.40

Step-by-step explanation:

well if you take his original pay (11.75) and add 0.25, you get 12.00 per hour.

12.00 + 2.5% raise would be:

12.00 + 0.3 or 30 cents, so the pay per hour is 12.30.

then take 12.30 x 38 and you should get $467.40

so after both raises, and 38 hours of work, he will earn $467.40
