Answer:

56.25 degrees

Step-by-step explanation:

This is dealing with an adjacent and hypotenuse variable, so you use cosine. Since your want to find the angle, u have to use cos^-1 times 5 over 9. Because when you use cosine its adjacent over hypotenuse. cos^-1(5/9)

Answer:

56.3°

Step-by-step explanation:

You first have to figure out what you are going to use to find Angle B ( tanФ, cosФ or sinФ).

In this case you would use CosФ because you are given "adjescent over hypotenuse." Hence, 5/9.

Once you plug in CosФ=5/9 into your calculator you will get the angle of B. Which is: ∠B= 56.2510114°. Lastly, you would round this answer to the nearest hundredth.

Hope this helped! If you have any questions feel free to comment them.

A bottle contains 30 fluid ounces of orange juice and 18 fluid ounces of pineapple juice. Which graph has a slope that best repr

mojhsa [17]

Answer:

option B. G

Step-by-step explanation:

Let

y ---->ounces of orange juice

x ---> ounces of pineapple juice

we know that

The ratio of orange juice to pineapple juice is equal to

$ratio=\frac{y}{x}$

substitute the given values

$ratio=\frac{30}{18}$

simplify

$ratio=\frac{5}{3}=1.67$

Verify each graph

Remember that the formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

we have

$ratio=\frac{5}{3}$

that means

5 ounces of orange juice per 3 ounces of pineapple juice

Graph F

The slope is

$m=\frac{4}{6}=\frac{2}{3}=0.67$

Graph G

The slope is

$m=\frac{4}{2}=\frac{2}{1}=2$

Graph H

The slope is

$m=\frac{70}{6}=\frac{35}{3}=11.67$

Graph J

The slope is

$m=\frac{12}{10}=\frac{6}{5}=1.2$

The value of 2 is the value closest to 1.67

therefore

The graph that has a slope that best represents the ratio of orange juice to pineapple juice is Graph G

PLEASE HELP!!!!! Florian ran 1.2 miles and walked 4.8 laps around the path at the park for a total distance of 3.6 miles. Which

fgiga [73]

Answer:

The correct answer would be D) 4.8x + 1.2 = 3.6; x = 0.5 mile

Step-by-step explanation:

This is because laps would be the dependent variable, so we know the number of them (4.8) would be multiplied by the variable (x). We also know that 1.2 is the constant. Now we can solve to make sure this is the right equation.

4.8x + 1.2 = 3.6

4.8x = 2.4

x = 0.5

The volume of a cube is related to the area of s face by the formula v= a^3/2. What is the volume of a cube whose face has an ar

Sophie [7]

Answer:

1000 m³

Step-by-step explanation:

Put the number into the formula and do the arithmetic.

v = a^(3/2) = (100 m²)^(3/2) = (√100)³ m³ = 1000 m³

The volume is 1000 cubic meters.

3. What is the measure of angle B from the right triangle below?

Talja [164]

Answer:

angle B = 78.46°

Step-by-step explanation:

Use the cosine ratio

$cosB=\frac{2}{10} =0.2$

$B=cos^{-1} (0.2)=78.46^{0}$

What is the area of the triangle? 6 2 3

Llana [10]

Answer:

Step-by-step explanation:

Find the area of both triangles inside the bigger triangle and add them together.

Use the Pythagorean theorem to find the missing length of the leg in the smallest triangle:

a² + b² = c²

2² + b² = 3²

4 + b² = 9

5 = b²

2.2 ≈ b

Calculate the area of the smaller triangle:

1/2(bxh)

1/2(2 x 2.2)

1/2(4.4)

2.2

Calculate the area of the bigger triangle:

We know that the longer leg is 3.8 units because we were able to subtract the length of the smaller triangle's leg from 6.

1/2(bxh)

1/2(2 x 3.8)

1/2(7.6)

3.8

Add both areas to find the area of the largest triangle:

3.8 + 2.2 = 6
