To get the balance after 3 years we use the formula:

A=P(1+r/100)^n

where:

A=future amount

r=rate

n=time

thus plugging in the values we obtain:

A=500(1+4/100)^3

A=500(1+0.04)^3

A=500(1.04)^3

The correct choices are A and B

The wrong choices are C and D

A=P(1+r/100)^n

where:

A=future amount

r=rate

n=time

thus plugging in the values we obtain:

A=500(1+4/100)^3

A=500(1+0.04)^3

A=500(1.04)^3

The correct choices are A and B

The wrong choices are C and D

Question

Use the graph below to answer the question that follows: graph of the curve that passes through the following points, 0, 3; pi over 2, 5; pi, 3; 3 pi over 2, 1; 2 pi, 3. What is the rate of change between the interval of x = 0 and x = pi over two? 2 over pi pi over two pi over four four over pi

Solution 1

The **rate **of **change **is 4/π which is the correct **answer **would be **option **(**D**)

A **graph **can be defined as a pictorial representation or a diagram that represents **data **or **values**.

The **slope **of a line is defined as the angle of the line. It is denoted by m

Slope m = (y₂ - y₁)/(x₂ -x₁ )

Consider two **points **on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)

The coordinates of the endpoints of the **range **can be used to determine the **rate **of **change **using the slope formula: m = dy / dx.

The coordinates are

x₁=0, y₁=3

x₂=π/2, y₂=5

So rate of change = (y₂ - y₁)/(x₂ -x₁ )

Rate of change = (5-3)/(π/2-0)

Rate of change = 4/π

#SPJ5

Solution 2

X1=0, y1=3

x2=pi/2, y2=5

rate of change = (y2-y1)/(x2-x1)

=(5-3)/(pi/2-0)

=4/pi

ans is D. four over pi

x2=pi/2, y2=5

rate of change = (y2-y1)/(x2-x1)

=(5-3)/(pi/2-0)

=4/pi

ans is D. four over pi

Question

A cylinder has a radius of 5 feet and a height of 8 feet. Which of the following can be used to calculate the volume of a cone that fits exactly inside the cylinder? A. (3.14)(5^2)(8)
B. 1/3(3.14)(5^2)(8)
C. (3.14)(8^2)(5)
D. 1/3(3.14)(8^2)(5)

Solution 1

The formula is pi*r^2*h/3

your answer would have to be B

your answer would have to be B

Question

Tanisha is planning a backyard party. She will serve hamburgers, potato salad, strawberry shortcake, and lemonade. Including Tanisha, 28 people will be at the party. Use this information to help Tanisha plan her party. Tanisha expects that each person will drink two 8−ounce glasses of lemonade at the party, and makes 448 ounces of lemonade. Tanisha's mother buys 38 lemons. They know it takes 8 lemons to make 80 ounces of lemonade. Does Tanisha need more lemons?

Solution 1

For this case we can make the following rule of three:

8 lemons --------> 80 ounces of lemonade

38 lemons ------> x

Clearing x we have:

x = (38/8) * (80)

x = 380 ounces

We observed that:

380 <448

Therefore, more lemons are needed.

**Answer:**

**Yes, Tanisha needs more lemons**

8 lemons --------> 80 ounces of lemonade

38 lemons ------> x

Clearing x we have:

x = (38/8) * (80)

x = 380 ounces

We observed that:

380 <448

Therefore, more lemons are needed.

Question

PLS HELP! Tanisha is planning a party. She will serve hamburgers, potato salad, strawberry shortcake, and lemonade. Including Tanisha, 28 people will be at the party. Tanisha expects that each person will drink two 8−ounce glasses of lemonade at the party, and makes 448 ounces of lemonade. Tanisha's mother buys 38 lemons. They know it takes 8 lemons to make 80 ounces of lemonade. Does Tanisha need more lemons?

Solution 1

Shee needs 448 ounces of lemonade.

448 ÷ 80 =5.8

⇒ There are 5.6 80-ounce of lemonade.

80 ounces of lemonade needed 8 lemons.

448 ounces of lemonade needed 8 x 5.6 = 44.8 lemons.

Tanisha has 38 lemons.

She does not have enough lemons.

She needs 44.8 - 38 = 7 more lemons.

**Answer: ****Tanisha needs more lemons. She needs 7 more.**

448 ÷ 80 =5.8

⇒ There are 5.6 80-ounce of lemonade.

80 ounces of lemonade needed 8 lemons.

448 ounces of lemonade needed 8 x 5.6 = 44.8 lemons.

Tanisha has 38 lemons.

She does not have enough lemons.

She needs 44.8 - 38 = 7 more lemons.

Solution 2

**Answer: 7 more lemons**

**Step-by-step explanation:**

Since she needs 448 ounces of lemonade you have to divide which is 5.6 . As a result there are 5.6 80 ounces of lemonade. 80 ounces needs 8 lemons. 448 ounces of lemonade are needed 8 x 5.6 = 44.8 lemons. Tanisha only has 38 lemons, which isn't enough. 44.8 - 38 = is about 7 more lemons.

Question

Please help me -3x-3x=-24

Solution 1

-3x - 3x = -24

Combine like terms:

- 6x = -24

Divide both side by -6:

x = 4

**Answer: x = 4**

Combine like terms:

- 6x = -24

Divide both side by -6:

x = 4

Question

Question

Where can the numerator be found in a fraction? A. Above the fraction bar
B. At the fraction bar
C. Below the fraction bar
D. Either A or C

Solution 1

The answer is A. above the fraction bar. The denominator lives below the fraction bar.

Question

What is the excluded value of -2x/17
a. x=0
b. x=2
c. x=17
d. no excluded values

Solution 1

Answer is d: no excluded values.

There is only excluded values if the variable x is in the denominator.

There is only excluded values if the variable x is in the denominator.

Question

A circle has a circumference of 10. It has an arc of length 9/2

Solution 1

Given that a circle has a circumference of 10 and an arc of length 9/2, thus the fraction of the arc length will be:

(9/2)/10

=0.45

thus the angle subtended by the arc will be:

0.45×360°

=162°

(9/2)/10

=0.45

thus the angle subtended by the arc will be:

0.45×360°

=162°

Question

Anja collected data about the number of dogs 9th-grade students own. She created this histogram to represent the data and determined that it is skewed right. Which statement is true about Anja’s claim?
