Answer:

The answer is 170 feet

This is how to solve the question

When you are below sea level it means that you are at a negative (in math terms)

So you are 50 feet below sea level and you want to get to a place that is 120 feet high

So you take 50 into account because your starting below sea level then you add 120 for the distance to get up the mountain

120+50= 170

Answer:

The temperature of the water when the first race started was 78.1 degrees

Step-by-step explanation:

Addition

The temperature of the water of a pool was 72.5 degrees when the swimmers first arrived.

By the time when the first race started, the temperature had increased by 5.6 degrees.

To find the temperature at that very moment we have to add 72.5 degrees + 5.6 degrees = 78.1 degrees

The temperature of the water when the first race started was 78.1 degrees

Answer:

39,055

Step-by-step explanation:

so you say 6 over 100 multiplied by $36,500 over 1. then 100 into 36,500 then you get 365. then you say 6 multiplied by 365 and you get 2,555. then you say 2,555 plus 36,500 then you get 39,055

Answer:

Here is you graph

Step-by-step explanation:

:)

Answer:

y = 3x

Step-by-step explanation:

A proportional function has the equation

y = kx, where k is the constant of proportionality and also the slope of the line.

Answer: y = 3x

The equation that represents the line whose slope of proportional relationship is 3 is; y = 3x.

The slope of the proportional relationship as given is 3.

However, the equation of the line which represents a proportional relationship usually takes the form; y = Mx.

Since, slope, m = 3.

The equation of the line is; y = 3x.

Step-by-step explanation:

Answer:

There's a proportion relationship between number of shell and their cost

Step-by-step explanation:

The graph is not given.

However, I've added the appropriate graph as an attachment.

From this, point....

I'll show that the cost and number of shells as given in the question are proportional.

Represent cost with y and number of shells with x

x = 2 when y = 0.8

x = 3 when y = 1.2

x = 4 when y = 1.6

Divide each value of y by x to get the constant of proportion (r).

r = y/x

r = 0.8/2 = 0.4

r = 1.2/3 = 0.4

r = 1.6/4 = 0.4

Notice that the values of r remain constant.

Hence, there's a proportion relationship between both

And what this rate represent is that:.the cost of shell changes at a constant rate when the number of shell is changes.

Answer:22

Step-by-step explanation:

Answer:

Step-by-step explanation:

let x be chickens and y be cows

x+y=15

x=15-y

2x+4y=44, using x=15-y

2(15-y)+4y=44

30-2y+4y=44

2y+30=44

2y=14

y=7, since x=15-y

x=8

So there are 8 chickens and 7 cows.

Answer:

Linear function

Step-by-step explanation:

Given

[tex]f(x) = -\frac{1}{4}x + 5[/tex]

Required

Linear or Exponential

A linear equation has the form: [tex]f(x) = mx + c[/tex];

An exponential has the form: [tex]f(x) = ab^x[/tex]

By comparing both functions to: [tex]f(x) = -\frac{1}{4}x + 5[/tex]

The linear function is similar to [tex]f(x) = -\frac{1}{4}x + 5[/tex]

Hence, the given function is a linear function.

Answer:

So you take 3.4 and subtract from 6.6 which equals 3.2. Then if you add 3.4+3.2= 6.6. Hope this helps.

Step-by-step explanation:

Sorry I am late hope this helps

Sample Response:

Sum means the result of adding two numbers. The bar diagram represents that an unknown number and 3.4 together make 6.6. So 3.4 + what number equals 6.6? The result is 3.4 + 3.2 = 6.6. The sum of 3.4 and 3.2 is 6.6.
