b)5.8

another help again

Answer:

5.6 , 5.8

Step-by-step explanation:

We have 4 numbers with two missing numbers in between them and are asked to fill it in.

So we see that 5.2 and 5.4 are present, just with this information we can tell what is next by subtracting them.

5.4 - 5.2

0.2

Therefore, for every number, 0.2 is being added.

Meaning that 5.4 + 0.2

5.6

5.6 + 0.2

5.8

5.8 + 0.2

6.0

This fits the sequence.

Clare's recipe for banana bread won't fit in her favorite pan. The pan is 8 1/2 inches by 11 inches by 2 inches. The batter fills the pan to the very top, and when baking, the batter spills over the sides. To avoid spills, there should be about an inch between the top of the batter and the rim of the pan. Clare has another pan that is 9 inches by 9 inches by 2 1/2 inches. If she uses this pan, will the batter spill over during baking?

Answers

Melanie can run around the track 9 times in 28 minutes. At this rate, how many laps can she run in 1 hour and 15 minutes?

Answers

Step-by-step explanation:

First step is to identify what the problem is asking for and what is given.

9 laps in 28 minutes

Searching for number of laps in 1 hour and 15 min.

1 hour + 15 min. = 75 minutes convert to minutes

9 laps / 28 minutes = x laps / 75 minutes create an equation

9/28 = x/75

9*75 = 28x cross multiply

675 = 28x

x = 675/28 = 24.12 simplify

Melanie can run 24 complete laps in 1 hour and 15 minutes.

The owner of a resale shop is analyzing the revenue for the year. Profit is modeled by the function p(x) = x2 – 14x + 485, where p(x) represents profit and x represents the number of items sold. How many items must he sell in order for his profit to be $500?

Answers

Answer:

hope this helps with other things have a a good day

Step-by-step explanation:

The required number of items the owner must sell is 15 items so he can earn a $500 profit.

Given that,
Profit is modeled by the function p(x) = x2 – 14x + 485, where p(x) represents profit and x represents the number of items sold. How many items must he sell in order for his profit to be $500 is to be determined.

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
500 = x² - 14x + 485
x² - 14x - 15 = 0
x² - 15x + x - 15 = 0
x (x - 15 ) + 1 (x - 15 ) = 0
(x - 1 ) (x - 15 ) = 0

Number of items he must sell to earn $500 profit,

x - 15 = 0
x = 15

Thus, the required number of items the owner must sell is 15 items so he can earn a $500 profit.

A circular fountain has a radius of 9.4 feet. Find its diameter and circumference to the nearest hundredth. ( Please help)

Answers

A circle is 360 and it has a radius then 9.4 you will get 40.7

Answer:

The diameter is 11.20 feet. The circumference is approximately 35.17 feet.

Step-by-step explanation:

Use the formula.

d = 2r The diameter of a circle is the same as 2 times the radius.

d = 2(5.6) The radius is 5.6. Substitute 5.6 for r.

d = 11.20 Multiply.

Use the formula.

C = πd

C = π(11.20) The diameter is 11.20. Substitute 11.20 for d.

C ≈ 3.14(11.20) Substitute 3.14 for π.

C ≈ 35.17 Multiply.

The diameter is 11.20 feet.

The circumference is approximately 35.17 feet.
