13.50xy, which shows that Harriet earns $13.50 every two hours she works.

Answers

The equivalent expression that correctly describes the situation is:

13.50xy, which shows that Harriet earns $13.50 for each hour she works.

This expression represents the total amount of money Harriet earns at both jobs, where x represents the number of hours worked at job X and y represents the number of hours worked at job Y. The coefficient of xy, which is 13.50, represents the amount of money Harriet earns per hour, regardless of which job she is working. Therefore, this expression accurately reflects the situation described

★ . what is the original length of the board ?

★ . what is the length that was cut off ?

★ . write and solve an equation .

★ . the length of the board that is left is ?

Answers

Answer:

   The original length of the board is 8 feet.

   The length that was cut off is 2 feet.

   One possible equation we can use is: x = 8 - 2, where x represents the length of the board that is left. Solving for x, we get x = 6 feet.

   The length of the board that is left is 6 feet.

Step-by-step explanation:

We are given that the board was originally 8 feet long. Bryce cuts off 2 feet from the board to use for a project. Therefore, the length of the board that is left is 8 - 2 = 6 feet.

To solve this problem algebraically, we can set up an equation where x represents the length of the board that is left. We know that the original length of the board is 8 feet, and 2 feet was cut off, so we can write:

x = 8 - 2

Simplifying this equation gives us:

x = 6

Therefore, the length of the board that is left is 6 feet.

A cylindrical of oatmeal canister has a diameter of 4 inches and a height of 10 inches. The manufacturing company wants to package the oatmeal in square containers to cut back on wasted storage space. If the new carton has a square base with 4 inch sides, what is the minimum height it must have, to the nearest 1/4 inch, to hold the same volume of oatmeal? Use 3.14 for the value of π.

Answers

Step-by-step explanation:

Volume of cylinder = pi r^2 h

Volume of square container = s x s x h

they need to be equal

pi r^2 h = s^2 h

pi (2)^2 * 10   = 4^2 h            (diameter = 4   then radius = 2)

40pi / 16 = h = 7.9 in  = ~ 8 in   to the nearest 1/4 inch

Answers

Answer:

1017 cm³

Step-by-step explanation:

To find the volume of this figure we will first need to divide it into 2 sections. First, we will find the volume of the semicircle on top then the cone at the bottom!

1) Semicircle

The simplest way of doing this is to find the volume as if it was a circle and then divide that result by 2! ([tex]\frac{4}{3}[/tex]πr³)

[tex]\frac{4}{3}[/tex] × 3.14 × 6³ = 904.32904.32 ÷ 2 = 452.16

2) Cone

To find the volume of the cone we need to apply the equation πr²[tex]\frac{h}{3}[/tex] (where h = height)

3.14 × 6² × [tex]\frac{15}{3}[/tex] = 565.2

3) Add

452.16 + 565.2 = 1017.361017 rounding to the nearest whole number!

System:

[tex]x+y=125[/tex] is also [tex]y=-x+125[/tex]

b. What percent of the students had birds?

c. How many total students did Bryan interview?

Answers

Answer:

60% of the students have dogs

10% of the students have birds

Bryan interviewed 200 students

Step-by-step explanation:

a.3/5 = 60%

b.60% + 30% = 90%

100% - 90% = 10%

c. 20 x 10 = 200

Answer: 60%, 10%, 200 students.

Step-by-step explanation:

Let's start with turning all of the values into percentages.

3/5 of the students said dogs. As a percentage, 3/5 is equal to 60%.

We now have two percentages, the amount of cats and the amount of dogs. 30%+60%=90%. So that leaves 10%, and that 10 percent is the 20 students who had birds.

If 20=10%, all we have to do is multiply 20 ten times to get to 100%. 20x10=200.

There were 200 students interviewed.

The following table shows several ordered pairs of a function, m(x)

Graph m(x) on a coordinate plane to determine whether or not the function represents a direct variation. In complete sentences, describe your conclusion and reasoning. Include your graph in your answer.

Answers

Answer:

  m(x) = 1.5x . . . . direct variation

Step-by-step explanation:

You want to know if the function m(x) represents direct variation, given a table of values.

Direct variation

An equation for direct variation is ...

  y = kx

where k is a constant that can be found as the ratio of any (x, y) pair:

  k = y/x

  k = -1.5/-1 = 1.5/1 = 3/2 = 6/4 = 1.5

The ratios are constant, hence m(x) is direct variation with a constant of variation of 1.5.

Graph

The graph of direct variation is a straight line through the origin. The given points lie on such a line.

Do you notice any points on the graphs that are an extreme value? What does this tell you?
