Kelly is on a four-person relay team. The team's total time for its last race was 41.37 seconds. Giselle ran her part in 9.36 seconds. Sarah took 9.71 seconds to run her part of the race, and Aliyah ran her part in 10.57 seconds. How long did Kelly take to run her portion of the race?
Answer: 11.73 seconds
Step-by-step explanation:
To solve the question, we have to add the time used by Giselle, Sarah and Aliyah and then subtract from 41.37 seconds to determine the time used by Kelly. This will be:
= 41.37 - (9.36 + 9.71 + 10.57)
= 41.37 - 29.64
= 11.73 seconds
Kelly used 11.73 seconds
The area of a circle is 16π m². What is the circumference, in meters? Express your answer in terms of pi
*hint 8 isnt the answer *
brainlest
pls hurry
Solution:
We know that:
Area of circle = πr² = 16π
Let's undo this equation by dividing π both sides. Then, take a square root to find the radius.
=> πr² = 16π=> πr²/π = 16π/π=> r² = 16=> √r² = √16=> r = 4Now, let's find the circumference by substituting the radius in the circumference formula.
=> 2πr = Circumference=> (2)(π)(r) = Circumference=> (2)(π)(4) = Circumference=> 8π meters = CircumferenceSince the question says to leave the circumference in terms of π, 8π meters is the circumference of the circle.
Thus, the circumference is 8π meters

If a ∥ b and m∠1 = 65°, what is m∠2?
Answer:
65 degrees
Step-by-step explanation:
the angles are corresponding, and corresponding angles always have the same angle measures
If a ∥ b and m∠1 = 65°, The measure of m∠2 will be 65°.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called an "Angle." when a transverse line crosses two straight lines, corresponding angles are formed.
When two lines are crossed by a third line, these angles are generated at equivalent corners or corners corresponding to the transversal.
It is given that, a ∥ b and m∠1 = 65.
If the transversal meets two parallel lines, the corresponding angles theory asserts that the corresponding angles are congruent. In other words, the angles formed when a transversal crosses two parallel lines will always be equal.
Since corresponding angles always have the same angle measures, the angles are said to be corresponding.
As a result,
m∠1 =m∠2
m∠1 = 65°
m∠2=65°
Thus, if a ∥ b and m∠1 = 65°, The measure of m∠2 will be 65°.

Solve for p in the literal equation 9p + 7r = q.
Answer:
p = [tex]\frac{q-7r}{9}[/tex]
Step-by-step explanation:
Given
9p + 7r = q ( subtract 7r from both sides )
9p = q - 7r ( isolate p by dividing both sides by 9 )
p = [tex]\frac{q-7r}{9}[/tex]
Answer: p = q - 7r ÷ 9
Rhonda went out to dinner.
• The price of her meal was
$15.55.
• The sales tax was 7% of the
price of the meal.
• The tip was 18% of both the
meal and the sales tax.
How much money did Rhonda
pay for the meal, including tax
and tip?
Answer:
18.54
Step-by-step explanation:
15.55 X 7% = 1.0885
15.55 + 1.0885 = 16.6385 X 18% = 2.99493
15.55 + 2.99493 =18.54493
