Engineers are playing a new bridge to cross a small river. Surveyors created the diagram to show where the bridge across the river.

What is the distance across the river where the new bridge will be built?

A. 36 feet
B. 56.25 feet
C. 100 feet
D. 101.25 feet

Answer:

1,500 kilometers

Step-by-step explanation:

To find 75% of 2,000, multiply 2,000 by .75. That gets us 1,500. That means 75% of a 2,000 kilometer trip is 1,500 kilometers.

Answer:

1,500 kilometers

Answer:

-25/36

Step-by-step explanation:

-5/6 x 5/6 = -25/36

There is no way to simplify it.

You just needed to multiply the deniminators and the numerators. And since you can't simplity -25/36, you have your answer.

Answer:

C. -25/36

Step-by-step explanation:

-5/6 x 5/6 = -25/36

There is no way to simplify it.

You just needed to multiply the deniminators and the numerators. And since you can't simplity -25/36, you have your answer.

Answer:

The helicopter is 27.38 m far off the ground

Step-by-step explanation:

The drawing shown in the image below has all the measures and variables needed to solve the problem.

We need to find R, the height of the helicopter. We'll use the law of sines to find the length of side a.

[tex]\displaystyle \frac{28}{\sin X}=\frac{a}{\sin 54^\circ}[/tex]

The angle X is the measure needed to complete 180°:

X = 180° - 54° - 62° = 64°

Solving for a:

[tex]\displaystyle a=\frac{28}{\sin 64^\circ}\cdot \sin 54^\circ[/tex]

Calculating:

a = 31.11 m

Now using the sine ratio in the right triangle to the left side:

[tex]\displaystyle \sin 62^\circ=\frac{R}{a}[/tex]

Solving for R:

[tex]R=a\sin 62^\circ[/tex]

R=31.11*0.88

R = 27.38 m

The helicopter is 27.38 m far off the ground

first you divide the price by four then add a quarter to the original amount. gl

Answer:

the answer is -5

Step-by-step explanation:

simply put the slope is going down one unit so that would me that for every one year equals 5lb so the would make the ratio 5/1 and when we simply that we get -5 for the first year or range they want us to answer.(And its negative because the slope is going down for the range they give us)

Answer:

Y=4 when X =24

Step-by-step explanation:

If Y varies directly with X,  find Y when X=24, if Y = 5  when X= 30.​

We can write:

[tex]Y\:\alpha\: X\\Y=kX[/tex]

Where k is known as constant of proportionality

Now, we are given: Y = 5  when X= 30.​

We can find value of k

[tex]Y=kX\\5=k(30)\\k=\frac{5}{30}\\k=\frac{1}{6}[/tex]

Now, we will find Y when X = 24

and k=1/6

[tex]Y=kX\\Y=\frac{1}{6}(24)\\Y=4[/tex]

So, Y=4 when X =24.

bro i do not know how to do that stuff im only in Middle school my guy

Step-by-step explanation:

Answer:

y = -1/4x + 8

Answer:

Jessica has x amount of dollars.

Sarah has 4x + 3

Together they have $72

We can combine Jessica and Sara's money to equal $72.

x + (4x + 3) = 72

Combime like terms

5x + 3 = 72

Subtract 3 from both sides to isolate the variable.

5x = 69

Divide both sides by 5

x = 69/5 or 13 4/5 or 13.80

Jessica has $13.80 and

Sarah has 4(13.80) + 3

55.20 + 3 = 58.20

Work Shown:

Plug x = 4.3 into the equation given

ŷ = 2.6 − 3.1x

ŷ = 2.6 − 3.1(4.3)

ŷ = 2.6 − 13.33

ŷ = -10.73

Note: The symbol ŷ is read as "y hat". It's used to estimate the y value when it comes to regression equations.

Answer:

24.9%

Step-by-step explanation:

95/382=0.24869

0.24869*100=24.87

24.87% rounded up to the nearest tenth of a percent is 24.9%

Answer:

50 square centimeters

Step-by-step explanation:

Long means length, and we know the length of the label, 10 centimeters. That means the width is half of 10 centimeters, or 5 centimeters. Now, we multiply 10 and 5 to get 50. That means the area of the label is 50 square centimeters

Answer:

x<3

Step-by-step explanation:

the dot is not black so it means that its not equal to three but bigger than three

[tex]A \ system \ is \ composed \ o f \ 5 \ components \ , \ e ach \ of \ which \ is \ either \ working \ or[/tex][tex]failed. \ Consider \ an \ experiment \ that \ consists \ of \ observing \ the \ status \ of \ each[/tex][tex]component \ . and \ let \ the \ outcome \ of \ the \ experiment \ be \ given \ by \ the \ vector[/tex][tex](x1,x2,x3, x4, x5), \ where \ xi \ is \ equal \ to \ 1\ if \ component \ i \ is \ working \ and \ is \\ equal \ to \ 0 \ if \ component \ i \ is \ failed.[/tex]

Answer:

Step-by-step explanation:

From the given information:

We learned that it is possible that all entities can be in one of two states i.e. 0 or 1. Thus, all 5 entities can either be 0 or 1 (2 states).

∴

Number of outcomes = 2 × 2 × 2 × 2 × 2

= 2⁵

= 32

b)

All the outcomes of W = {(1, 1, x₃, x₄, x₅) (x₁, x₂, 1, 1, x₅) (1, x₂, 1, x₄, 1)}

Answer:

D

Step-by-step explanation:

Answer:

7/3

Step-by-step explanation:

L.C.M of all of the denominators is 12

We get,
