A fraction represents a part of a whole.40/70, 21/70 are the same fractions like 4/7 and 3/10 with same denominator.

What is a fraction?

A fraction represents a part of a whole

We need to write 4/7 and 3/10 with the same denominator

The given fractions are 4/7 and 3/10

in 4/7

If numerator and denominator is multiplied with 10

4/7*10/10

we get

40/70

i.e 4/7=40/70

Now

in 3/10

If numerator and denominator is multiplied with 10

3/10*7/7

we get

21/70

i.e 3/10=21/70

Therefore 4/7=40/70 and 3/10=21/70 are two fractions with same denominator.

12. Water is being pumped into a pool at a constant rate of 8.25 gallons per minute. If the pool contained 1250
gallons of water initially, write a function for the number of gallons of water, g(t),in the pool after t minutes
of pumping water into the pool.

Answers

Answer:

[tex]g(t)=8.25t+1250[/tex]

Step-by-step explanation:

You can input any value for t, and that would give you the amount of water pumped in. Then, the +1250 represents the initial 1250 gallons that are in the pool.

Ernest works in the shipping department at Wal-Mart. Each
Empty crate weighs 150 lbs. How many boxes, each weighing 35
lbs. can Ernest put in the crate if the total weight is to be at most 850
Ibs?

Answers

Max weight of the crate - the empty crate/ by 35 (the weight of the individual boxes)

850-150=700

700 lbs is the remaining weight available that can be filled with 35 lb boxes, to find out the number of boxes that can be added to the crate, divide 700 by 35.

700/35 = 20

Ernest can put in 20 boxes in the crate.

California has 143deaths from heart disease and 137deaths from cancer per100,000 residents. Which rate is more extreme compared to other states? A.Perform any needed computations here: b. Is California's rate for heart disease or for cancer more extreme compared to the other states? Explain:

Answers

Answer:

California's rate for heart disease is more extreme than Cancer

Step-by-step explanation:

Given

Represent Cancer with C and Heart Disease with H

H = 143

C = 137

Population = per 100,000

First we need to determine the probability of both.

For H

P(H) = H/100000

P(H) = 143/100000

P(H) = 0.00143

For C

P(C) = C/100000

P(C) = 137/100000

P(C) = 0.00137

By comparison,

0.00143 > 0.00137

So, California's rate for heart disease is more extreme than Cancer.

Reason: P(H) > P(C)

please estimate the answer to
23.4x13.8/0.18

Answers

Ans: -1 -1/5

First you’d figure out what 1 9/10 is but added 10/10 to 9/10

19/10


Then you would subtract


7/10 - 19/10 = -12/10


-12/10 = -1 -2/10


In simplest form,

-1 -2/10

Would be

-1 -1/5

Find a value for k such that the following trinomial can be factored x^2-8x+k

Answers

Answer:

16

Step-by-step explanation:

x^2-8x+k is a quadratic expression of the form ax^2 + bx + c.  Here a = 1, b = -8 and c = k.  Focus on x^2-8x and complete the square as follows:  Take half of the coefficient of x (that is, take half of -8) and square the result:

(-4)^2 = 16; if we now write x^2-8x+ 16, we'll have the square of (x - 4):  (x -4)^2.

Thus, k = 16 turns x^2-8x+k into a perfect square.

What is the slope for (-1,2) and (1,16)

Answers

Answer:

The slope is 7.

Step-by-step explanation:

(-1, 2) and (1, 16)

Slope is found using the following formula:

(y₂ - y₁) / (x₂ - x₁)

First, let's label the coordinates (these can be in any order, as long as the second numbers in each coordinate are in the y slots and the first numbers are in the x slots:

y₂: 16

y₁: 2

x₂: 1

x₁: -1

Now, substitute into the original formula:

(y₂ - y₁) / (x₂ - x₁)

(16 - 2) / (1 - (-1))

Simplify

(14)/(2)

7

The slope is 7.

ninth grade algebra.i am solving for x​

Answers

Answer: x = 1

Step-by-step explanation:

So you need to get x completely alone, so take c out of it by subtracting c

-3x = -3 -2c

x = 1 +2/3c

so you would plug that in to solve for C

So you know what x is (or the substitute for it right now)

-3(1 + 2/3c) + 2c = -3

multiply or add

-3 - 2c + 2c = -3

c is 0 when you combine

-3x + 0 = -3

-3x = -3

x = 1
