Sean's mom asks him how long his homework will take. He tells her that he needs to read for 25 minutes and also do some math problems that will take m minutes. All together, his homework will take h minutes. Write an equation for the number of minutes Sean's homework will take h, if his math problems take m minutes

Answers

Answer: The required equation is $h=25+m.$

Step-by-step explanation: Given that Sean's mom asks him how long his homework will take.

He tells her that he needs to read for 25 minutes and also do some math problems that will take m minutes. All together, his homework will take h minutes.

We are to write an equation for the number of minutes Sean's homework will take h, if his math problems take m minutes.

Since Sean needs to read for 25 minutes and do some math problem for m minutes, so total time that Sean will take will be

$25+m.$

Also, since Sean takes h minutes altogether to complete his homework, so the equation is written as

$25+m=h\n\n\Rightarrow h=25+m.$

Thus, the required equation is $h=25+m.$

Answer:

h=25+m

If an ant runs randomly through an enclosedcircular field of radius 2 feet with an inner circle of
radius 1 foot, what is the probability that the ant will
be in the inner circle at any one time?
a.1/8
b 1/6
c 1/4
d.1/2
e 1

Answers

The area of a circle is π (radius²)

The area of the outer (2-ft) circle is π (2²) = 4 π square feet.

The area of the inner (1-ft) circle is π (1²) = 1 π square feet.

The inner circle covers 1/4 of the area of the outer circle.

So if the ant wanders around totally aimlessly and randomly, and there's no way to
know where he came from, where he is now, or where he's going next, and there's
an equal chance of him being anywhere in the big circle at any time, then there's a
25% chance of him being inside the small circle at any time, because 1/4 of the
total area is in there.

How many milliliters of olive oil (D=0.92 g/mL) have the same mass as 1.80 L of gasoline (D= .74 g/mL)

Answers

Answer:

1448 mL

Step-by-step explanation:

The mass is the same.

Formula

m = d*V

Givens

Olive Oil

d = 0.92 grams / mL

V = ??

Gasoline

d = 0.74 grams / mL

V = 1.8 L = 1.8 L * (1000 ml / L)

V = 1800 mL

Solution

0.74 * 1800 mL = 0.92 * x Divide both sides by 0.92

0.74/0.92 * 1800 mL = 0.92 *x / 0.92 Combine the left

0.8043 * 1800 mL = x

x = 1448 mL

The volume of Olive Oil needed is 1448 mL

The population of changed from 187.5 to 225. What was the percent increase?

Answers

You need to make 225 and 187.5 into a fraction like 187.5/225 then compare that to ?/100 to that you need to figure out what 225 divided by 100 is then divide that answer by 187.5. 225/100=2.25 187.5 divided by 2.25 is 83.3. 100- 83.3= 16.7 percent. You're right if you round it

Liam bought 5 7/8 pounds of steak. He used 2 1/16 pounds of the steak for a cookout. Liam has about how many pounds of steak remaining after the cookout?

Answers

Liam bought a total of 5 7/8 pounds of steak. Then he used 2 1/16 pounds of steak for a cookout.Given with the data above, let's find out how many pounds were left after he used some of it.=> Notice that the given numbers are fractions> => 5 7/8 pounds and 2 1/16 poundsSince these are mixed fraction, let's convert it to improper fraction. => 5 7/8 = (8 * 5 = 40 + 7 = 47) = 47 / 8=> 2 1/16 = (16 * 2 = 32 + 1) = 33 / 16The equation is now = 47/8 - 33/16=> Since they don't have the same denominator, let's find the lCD=> 47/8 - 33/16 = 94/16 - 33/16 = 61/16Let's change it to mixed fractions=> 61 /16 = 3.8 or => 3 . 8/100 = 3 2/25
