Answer:

Answer: 384 cm²

Step-by-step explanation:

Answer:

50ft

Step-by-step explanation:

Hi,

Considering that one side is equal to 38 degrees, we know this isn't a 30 - 60 - 90 triangle.

One of the legs is equal to 40 feet

So, tan(b) = 40/x

tan(38 degrees) is 0.78 round up to 0.8 (if that's what your teacher wants)

0.8 = 40/x

0.8x = 40

x = 50ft

I hope this helps

Answer:

5.618773 m2

I hope that this is the answer.

Answer:

answer is 60.48 m squared

Step-by-step explanation:

use the formula

a=1/2(b1+b2)h

a=1/2(15.8+6.6)h

a=1/2(22.4*5.4)

a=1/2(120.96)

a=120.96/2

a=60.48m

Answer:

[tex]\frac{9\sqrt{2} }{2}[/tex]

Step-by-step explanation:

This particular case is a sine operation.

sin(45°) = [tex]\frac{x}{9}[/tex]

9sin(45°) = x

Plug into a calculator and you get:

x = [tex]\frac{9\sqrt{2} }{2}[/tex]

Complete question :

A survey found that women's heights are normally distributed with mean 63.6 in and standard deviation 3.7 in. The survey also found that men's heights are normally distributed with mean 69.3 in and standard deviation 3.7 in. Consider an executive jet that seats six with a doorway height of 55.7 in.

1-What percentage of adult men can fit through the door without bending?

2-) Does the door design with a height of 56.35in. appear to be adequate? Why didn't the engineers design a larger door? Choose answer below

A. The door design is inadequate, because every person needs to be able to get into the aircraft without bending. There is no reason why this should not be implemented.

B. The door design is adequate, because the majority of people will be able to fit without bending. Thus, a larger door is not needed.

C. The door design is inadequate, but because the jet is relatively small and seats only six people, a much higher door would require major changes in the design and cost of the jet, making a larger height not practical.

D. The door design is adequate, because although many men will not be able to fit without bending, most women will be able to fit without bending. Thus, a larger door is not needed.

Answer:

A.) 0.135%

B.) C. The door design is inadequate, but because the jet is relatively small and seats only six people, a much higher door would require major changes in the design and cost of the jet, making a larger height not practical.

C.)

Step-by-step explanation:

Percentage of adult men that can fit the door without bending :

Obtain the Zscore :

Mean height of men, m = 67.5

Standard deviation, s = 3.7

Zscore = (x - m) / s ; where x = 56.4

Zscore = (56.4 - 67.5) / 3.7

Zscore = - 11.1 / 3.7

Zscore = - 3

P(Z < - 3) = 0.0013499 (Z probability calculator)

P(Z < - 3) = 0.0013499 * 100% = 0.13499%

Step-by-step explanation:

Answer: [tex]y=-\frac{3}{2}x+12[/tex]

Step-by-step explanation:

To find the equation of line B, we need to find the slope first, then the y-intercept. We first want to convert line A into slope-intercept form, so we can find the slope.

[tex]3x+2y=10[/tex]            [subtract both sides by 3x]

[tex]2y=10-3x[/tex]            [divide both sides by 2]

[tex]y=5-\frac{3}{2}x[/tex]

With the slope-intercept form of line A, we can see that the slope is [tex]-\frac{3}{2}[/tex]. We take the slope and the given point (4,6) to find the y-intercept of line B.

[tex]y=-\frac{3}{2}x+b[/tex]            [plug in (4,6)]

[tex]6=-\frac{3}{2}(4)+b[/tex]         [multiply]

[tex]6=-6+b[/tex]              [add both sides by 6]

[tex]b=12[/tex]

With the y-intercept, we know the equation for line B is [tex]y=-\frac{3}{2}x+12[/tex].

Answer:

D) Angle angle angle

Answer: 103832

Step-by-step explanation:

Answer:

Step-by-step explanation:

y=k[tex]\sqrt{x}[/tex]

60=k[tex]\sqrt{36\\}[/tex]  =k6

k=60/6 =10

This is your equation

y=10[tex]\sqrt{x}[/tex]

Put the numbers in

80=10[tex]\sqrt{x}[/tex]

80/10=8 then you have to square this so

[tex]8^{2}[/tex]=64

x=64

Answer:

See below.

Step-by-step explanation:

a. See pic below.

b. Yes because it passes the vertical line test. Any vertical line moving horizontally across the graph intersects only one point on the graph at a time.

c.

Domain: all real numbers

Range: all real numbers greater than or equal to 4

d.

Domain: all real numbers greater than or equal to 4

Range: all real numbers

e.

See pic below.

f. No because it does not pass the vertical line test.

you know that your line is perpendicular to the line with equation y equals 3x + 5 right whenever a line is perpendicular to another perpendicular not parallel to the line has a negative slope of the other line for example if you had a line with slope 2 x in the line perpendicular to that would have slope -1 / 2X so then you line in your question has slope -1 / 3 x by doing the Rococo of 3 and adding a negative sign to your equation sulfur looks like this y equals negative 1 / 3 x + B where is B is a constant 3 all you have to do is solve for b is a plug in the coordinate values 6 equals x minus -2 equals one in rearrange y equals -1 / 3 x + B negative two equals negative one over three 6 plus b negative two equals negative two plus be there for me easy roast F4U equation of the line is y equals -1 / 3 x

Answer:

∡b = 53°

∡d = 127°

∡c = 127°

Step-by-step explanation:

in trapezoids, the two top angles are equal and the two bottom are equal

also, there are 360 degrees in any 4-sided polygon

53 + 53 + x + x = 360

2x + 106 = 360

2x = 254

x = 127

Answer:

127

Answer:

1-    10% of -80 is -8.  

2-    28 is 4% of 700.

3-   25% of a number is equal to 1/4 or 0.25 of it.

4-    13% of a number is equal to 0.13 of it.

5-    15 is 12.5% of 120.

Step-by-step explanation:

1. 10% of ________- 8

2.28 is 4% of _________

3.25% of ________

4.13% of______

5.15 is 12.5% of _____

To determine the missing numbers in the statements, the following calculations must be performed:

1-

10 = -8

100 = X

100 x -8 / 10 = X

-800 / 10 = X

-80 = X

Therefore, 10% of -80 is -8.

two-

4 = 28

100 = X

100 x 28/4 = X

2800/4 = X

700 = X

Therefore, 28 is 4% of 700.

3-

25% of a number is equal to 1/4 or 0.25 of it.

4-

13% of a number is equal to 0.13 of it.

5-

12.5 = 15

100 = X

100 x 15 / 12.5 = X

1500 / 12.5 = X

120 = X

Therefore, 15 is 12.5% of 120.
