Answer:

$3,520

Step-by-step explanation:

If each square has a side length of 1/4 in then the dimensions of the Dining Room in the blueprint are:

  • Dining Room = (4 × 1/4) x (5 × 1/4) = 1 × 1.25 in

The scale given is 1 in : 16 ft, therefore dimensions of room scaled up:

  • Dining Room = (1 × 16) x (1.25 × 16) in = 16 × 20 ft

Therefore, the area of the Dining Room = 16 × 20 = 320 ft²

Given the hardwood floor costs $11 per ft², to find the total cost of the floor for the dining room:

Total cost = area × cost per ft²

                = 320 × $11

                = $3,520

Answer:

  • $3520

Step-by-step explanation:

<h3>Find the dimensions of dining room</h3>

<u>Width</u>

  • 4*1/4 in = 1 in
  • 1 in ⇒ 1*16 ft = 16 ft, according to scale factor

<u>Length</u>

  • 5*1/4 in = 1.25 in
  • 1.25 in ⇒ 1.25*16 ft = 20 ft
<h3>Find the area of dining room </h3>
  • A = lw = 16*20 = 320 ft²
<h3>Find the cost of flooring for the dining room</h3>
  • 320*11 = 3520

What is the bases, height, perimeter, and the area from the trapezoid​?<br><br>please help me
Sergio039 [100]

Answer:

base : 30 cm

height : 20 cm

perimeter : 92 cm

Area          :  400 cm

Step-by-step explanation:

base : 30 cm

height : 20 cm

perimeter : 27 + 30 + 25 + 10

                 : 92 cm

Area : (1/2 ( a + b) ) x h

        : (1/2 ( 10 + 30) ) x 20

        : (20) x 20

        : 400 cm

What is ∛2197? Explain how you got your answer.
user100 [1]

Answer:

13

Step-by-step explanation:

We need to write our answer in exponential form. Ask yourself the question, "What times itself 3 times will give you 2197?" Your answer is 13^{3}. This will go inside of your cube root. You now have \sqrt[3]{13^{3} }. Since there's a power of 3 and a cube root, those cancel each other out, and your answer is 13.

On a coordinate plane, rhombus W X Y Z is shown. Point W is at (7, 2), point X is at (5, negative 1), point Y is at (3, 2), and
Otrada [13]

Answer:

P = 4\sqrt{13}

Step-by-step explanation:

Given

W = (7, 2)

X = (5, -1)

Y = (3, 2)

Z =(5, 5)

Required

The perimeter

To do this, we first calculate the side lengths using distance formula

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2

So, we have:

WX = \sqrt{(5- 7)^2 + (-1 - 2)^2

WX = \sqrt{13}

XY = \sqrt{(3-5)^2 + (2--1)^2}

XY = \sqrt{13}

YZ = \sqrt{(5-3)^2 + (5-2)^2}

YZ = \sqrt{13}

ZW = \sqrt{(7 - 5)^2 + (2 - 5)^2}

ZW = \sqrt{13}

The perimeter is:

P = WX + XY + YZ + ZW

P = \sqrt{13}+\sqrt{13}+\sqrt{13}+\sqrt{13}

P = 4\sqrt{13}

In 2014, the CDC estimated that the mean height for adult women in the U.S. was 64 inches with a standard deviation of 4 inches.
Vladimir79 [104]

Answer:

A. 16%

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 64, \sigma = 4

Which of the following gives the probability that a randomly selected woman has a height of greater than 68 inches?

This is 1 subtracted by the pvalue of Z when X = 68. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{68 - 64}{4}

Z = 1

Z = 1 has a pvalue of 0.84.

1 - 0.84 = 0.16

So the correct answer is:

A. 16%
