25. time = distance/speed

It took about 432 milliseconds for the ball to travel to the batter.
26. 15 cans at Save Rite will cost 5 times the amount for 3 cans, so will be
... 5×$5.25 = $26.25
15 cans at Spend Less will cost 3 times the amount for 5 cans, so will be
... 3×$7.50 = $22.50
Maria paid $22.50 at Spend Less.
27. Simple interest is computed using
I = Prt . . . . where P is the principal, r is the annual rate, and t is the number of years.
Filling in the numbers gives the interest charge.
I = $8000×0.065×4 = $2080
Malik pays back the principal plus interest, so pays $8000 +2080 = $10,080.
Answer:

Step-by-step explanation:
The given equation is A=4 πr².
We need to solve the above equation for r².
We have,
A=4πr²
Dividing both sides by 4π, we get :

Hence, the value of r² is equal to
.
Answer:
n+8+6
Sum means = and and means + so n+8+6
Given:
The two numbers are 1280 and 630.
To find:
The HCF of the given numbers.
Solution:
First write the given numbers in prime factorization form.


Now the product of all the common prime factors is known as the HCF of 1280 and 630.


Therefore, the HCF of 1280 and 630 is 10.
