Answer: h = b/A

Explanation: If i hit 5 out of 10 balls thrown, my batting average is 2.

.5 = 5/10.

If my batting average is .5, and 10 balls were thrown, I only hit half or 5 of them. 5 = 10/.5

The mean and the average values are the same. They represent a dataset by calculating the central value.

The range can be understood as the variation of the data. The higher the range, the wider the variation.

From the table, we can see the average temperature of Rio de Janeiro is higher than in Caracas.

We can also see the variation of the temperature is higher in Caracas than in Rio de Janerio.

This corresponds to choice A.

As the circle is centered in the origin , we only need to know the radius of the circle. The radius is the distance from (0,0) to (-2,0) and it is 2. So the equation is

(-4,5)

4 to the left on the axis is neg. 5 units up on the y axis makes it positive.

The amount that a $90,000 loan cost Lauren than Demarcus will be $8280.

From the information, Demarcus and Lauren each take out a $90,000 loan for a new condo and each has to repay the loan in 10 years. It should be noted that 10 years in months will be:

= 10 × 12 = 120 months

The difference in the amount paid as a result of the credit score will be:

= ($840 × 120) - ($771 × 120)

= $100800 - $92520

= $8280

Therefore, the amount is $8280.

A. 1 1/2 cubic inches

Explanation:

We are told that the side length of the cube is 1/8 of an inch. Furthermore, we are also told that the rectangular prism fits 16 cubes along the length, 8 cubes along the width, and 6 cubes along the height. This means the measures of the dimensions of the prism are

Therefore, the volume of the prism is

Hence, the volume of the prism is 1 1/2 cubic inches

There are 38,936,000 people over the age of 64 were in the U.S.

Option 2 is true.

What is Percentage?

A relative value indicating hundredth part of any quantity is called percentage.

Given that;

In 2012, the U.S. population was about 314 million.

Now,

Total population = 314,000,000

In the pie chart, The percent of people over the age of 64 were in the U.S will be 12.4%

Hence, Solve as;

Number of people over the age of 64 = 314,000,000 × 12.4%

                                                           = 314,000,000 × 12.4 / 100

                                                           = 31,400,00 × 12.4

                                                           = 38,936,000

Thus,

There are 38,936,000 people over the age of 64 were in the U.S.

We are told that the weight of an object varies directly with the mass of the object. This basically means that if w is the weight and M is the mass then these two magnitudes are related by the following expression:

Where k is a constant.

We know that an object with a mass of 80kg weights 80 newtons. Then for this object we have w=80kg and M=80n so we get:

We divide both sides of this equation by 80:

Here it's important to remember that 1 newton (i.e. 1n) is equal to:

Then we get:

We divide both sides by 1 kg:

So now that we found k we have the following expression for the weight of an object as a function of its mass:

For an object that weights 70n we get:

We divide both sides by 1 m/s²:

So the mass of an object that weights 70n is 70kg.

Risky fund = $6,000

Step-by-step explanation:

Definition of variables:

Given information:

Convert the percentages into decimal form:

[tex]\implies 2.5\%=\dfrac{2.5}{100}=0.025[/tex]

[tex]\implies 8\%=\dfrac{8}{100}=0.08[/tex]

Create a system of equations from the given information and defined variables:

[tex]\begin{cases}0.025x+0.08y=1080\\x=4y\end{cases}[/tex]

Substitute the second equation into the first equation and solve for y:

[tex]\implies 0.025(4y)+0.08y=1080[/tex]

[tex]\implies 0.1y+0.08y=1080[/tex]

[tex]\implies 0.18y=1080[/tex]

[tex]\implies \dfrac{0.18y}{0.18}=\dfrac{1080}{0.18}[/tex]

[tex]\implies y=6000[/tex]

Substitute the found value of y into the second equation and solve for x:

[tex]\implies x=4(6000)[/tex]

[tex]\implies x=24000[/tex]

Therefore, the amount invested in each fund was:

a) g(x) = 10 + 0.5x

b) 17 days

Let the number of days be represented by x

Let the intial height of the zucchini plant be g₀

g₀ = 10 cm

Size of growth per day = 0.5 cm

Let the growth after x days be represented by g(x)

a) The rule that represents the function is therefore:

g(x) = g₀ + 0.5x

g(x) = 10 + 0.5x

b) After how many days will the Zucchini pant be 0.185 meters tall

That is g(x) = 0.185 meters

since 1 meter = 100 cm

g(x) = 0.185 x 100 cm

g(x) = 18.5 cm

Thereofre substitute g(x) = 18.5 into the equation g(x) = 10 + 0.5x

18.5 = 10 + 0.5x

18.5 - 10 = 0.5x

0.5x = 8.5

x = 8.5 / 0.5

x = 17

The zucchini plant will be 0.185 meters tall after 17 days

Answer:

x = 6 or x = 3

Step-by-step explanation:

Solve for x over the real numbers:

x^2 + 20 = 9 x + 2

Subtract 9 x + 2 from both sides:

x^2 - 9 x + 18 = 0

The left-hand side factors into a product with two terms:

(x - 6) (x - 3) = 0

Split into two equations:

x - 6 = 0 or x - 3 = 0

Add 6 to both sides:

x = 6 or x - 3 = 0

Add 3 to both sides:

Answer: x = 6 or x = 3
