Paula is running a race that is 10 kilometers long. After running 8
minutes, she passes the 3.75 kilometer marker. How many more
kilometers does Paula need to run to cross the finish line?

Answers

Answer:

10-3.75= 6.25 more kilometers

Step-by-step explanation:

The number of kilometers that Paola needs to run to cross the finish line will be 6.25 kilometers.

What is the length?

It is the measure of distance between the two points and is known as length. The length is measured in meters generally.

It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.

Paula is running a race that is 10 kilometers long. After running for 8 minutes, she passes the 3.75 kilometers marker.

Then the number of kilometers that Paola needs to run to cross the finish line will be given by the difference of 10 km and 3.75 km.

⇒ 10 - 3.75

⇒ 6.25 kilometers

Thus, the number of kilometers that Paola needs to run to cross the finish line will be 6.25 kilometers.

More about the distance link is given below.

1.) 90 Km/h. Example: What is the speed of a cheetah that travels 112.0 meters in 4.0 seconds? ... Speed of the cheetah in miles per hour 28m 1 mile 3600 s 63 miles

2.) y=kx is the direct variation formula. Inserting the information and variables from this scenario we get h = kn.

12 = k*(10) First solve for 'k', the constant of proportionality by dividing by 10.

1.2 = k

Next write the equation using this k and the h & n.

h = 1.2*n

Now we want to find the height if we have 24 books so plug 24 in for n.

h = 1.2 * 24

h = 28.8 inches

Heather deposits $7000 into an account that pays simple interest at a rate of 2% per year. How much interest will she be paid in the first 3 years?

Answers

Answer:

year after 3 year(s).

The formula we'll use for this is the simple interest formula, or:

Where:

P is the principal amount, $7000.00.

r is the interest rate, 2% per year, or in decimal form, 2/100=0.02.

t is the time involved, 3....year(s) time periods.

So, t is 3....year time periods.

To find the simple interest, we multiply 7000 × 0.02 × 3 to get that:

The interest is: $420.00

Usually now, the interest is added onto the principal to figure some new amount after 3 year(s),

or 7000.00 + 420.00 = 7420.00. For example:

If you borrowed the $7000.00, you would now owe $7420.00

If you loaned someone $7000.00, you would now be due $7420.00

If owned something, like a $7000.00 bond, it would be worth $7420.00 now.

420 dollars in 3 years

Simplify the expression:
–7c2–c2+–5c2–2c2+8c2–9c2

Answers

Answer:

the answer is why is math so hard

Step-by-step explanation:

Duh

i would start by grouping them into sections because they’re all like terms.
(-7c2-c2) = -8c2
(-5c2-2c2)= -7c2
(8c2-9c2) =-c2
then add them all together.
-8c2-7c2-c2
since they’re all negative you can add them together but don’t forget the negative.
8+7=15
15+1 = 16
add the negative back in to get -16c2
