A hot-air balloon rises 150 feet every 5 second. Which equation represents the relationship between time and height?

Answers

Answer:

y=30x

Step-by-step explanation:

the slope would be the change in height/time so 150/5 which is 30feet/sec

thus using the form y=mx+b and assuming the balloon started on the ground (0) then y=30x

Mr.Morton sold bird houses to stores. He started the week with 60. He sold ten to one store, and divided the rest between 5 other stores. How many birdhouses did he sell to each of the other 5 stores

Answers

Answer:

10

Step-by-step explanation:

10 to each

60 (original total) - 10 (sold to first store) =50 (leftover)
50 / 5 (amount of other stores getting birdhouses) = 10 (amount going to each of the last 5 stores)

a party rental company has chairs and tables for rent. the total cost to rent three chairs and five tables is $52. The total cost to rent 9 chairs and 7 tables is$86. what is the cost to rent each chair and each table?

Answers

Answer:

The cost for 1 chair is $2.75 and the cost for 1 table is $8.75.

Step-by-step explanation:

Use the elimination method of linear equations to find your answer.

Our equations for this problem are:

3c+5t=52 and 9c+7t=86

Multiply the entire first equation by -3.

-3(3c+5t=52)

Simplify the equation from above:

-9c-15t=-156

Stack the two equations on top of each other and add/subtract:

-9c-15t=-156

9c+7t=86

You should be left with -8t=-70. Simplify this to find the value of t:

t=8.75

Plug the value of t into any of the original equations and solve for c.

3c+5(8.75)=52

Simplify the equation above:

3c+43.75=52

Subtract 43.75 from both sides of the equation:

3c=8.25

Divide both sides by 3 to get your c value:

c=2.75

For f(x) = px +q and g(x) =
X-9), p70, find (fog)(x) and (g of)(x). Then determine whether (fog)(x) = (gof)(x).

Answers

Answer: f(x) = 2x

g(x) = x + 3

First let us find (fog)(x)

(fog)(x) = f(g(x)

= f(x+3)

= 2(x+3)

= 2x + 6

==> (fog)(x) = 2x + 6

Now let us find (gof)(x):

(gof)(x) = g(f(x)

= g(2x)

= 2x + 3

==> (gof)(x) = 2x + 3

HELP! find the value of x

Answers

Answer:

x = 12°

Step-by-step explanation:

To find the value of x, you have to subtract 65 from 180.

This is because angles on a straight line add upto 180 degrees, and 65 is the supplementary angle of 11x -17.

Hence,

11x - 17 + 65 = 180

11x + 48 = 180

11x = 132

x = 12

The distance that a person drives at a constant speed varies directly with the amount of time they have been
driving. If, at a particular speed, a person drives 107 miles in two hours, then how far will they drive, at the
same speed, in 14 hours?

Answers

Answer:

749 miles

Step-by-step explanation:

I divided 107 by 2 and then multiplied that by 14

a person drives 53.5 at that particular speed so they keep driving that amount of miles each hour so it's 749

The distance they will drive, at the same speed, in 14 hours is 749 miles.

Given the following data:

Distance A = 107 milesTime A = 2 hoursTime B = 14 hours

To find how far (distance) will they drive, at the same speed, in 14 hours, we would apply direct proportion:

By using direct proportion:

107 miles = 2 hours

X miles = 14 hours

Cross-multiplying, we have:

[tex]2X = 107 \times 14\\\\2X = 1498\\\\X = \frac{1498}{2}[/tex]

X = 749 miles

the value of y is 20% more than the value of x. the ratio of x:y = 5

Answers

Answer:

x:y = 5:6

Step-by-step explanation:

y = x(20/100) + x

y = x (1/5) + x

Factorize X

y = x (1/5 + 1)

y = x (6/5)

5y = 6x

-----------------------------

ratio x:y = 5:6

The ratio is x:y = 5:6.

What is ratio?

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same sort and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is expressed as a: b.

Given:

value of y is 20% more than the value of x

So,

y = x(20/100) + x

y = x (1/5) + x

y = x (1/5 + 1)

y = x (6/5)

5y = 6x

Hence, the ratio is x:y = 5:6.
