Citrus2011 [14]
First, we need to find the perimeter of the basketball court. To find the perimeter, you need to add all the sides of the shape, or in this case add the width(2) and height(2).

(32 x 2) + (17x2) = 64 + 34 = 98

the perimeter is 98 meters.

She drew a line around the perimeter, and the perimeter is 98 meters, so the line si also more or less 98 meters.

The correct answer is D.

Attendance dropped 6% this year to 300 what was the attendance before the drop?
mart [117]

Answer:

approx 4,130

Step-by-step explanation:

Answer this we have to multiply the attendance before the drop (x) by the percentage that assisted after the drop ( 1-0.08) . That expression must be equal to the attendance after the drop (3800)

Mathematically speaking:

8% = 8/100 = 0.08 (decimal form)

x (1-0.08)= 3800

x (0.92) =3800

Solving for x

x = 3800/0.92

x= 4,130

List two primes that are consecutive natural numbers. can there be any​ others?
vlabodo [156]
Out of every two consecutive numbers one will always be even. There is only one even prime number. Whether there are an infinite number of pairs of primes which differ by two (the twin prime conjecture) is still open e.g. 3 , 5; 41 , 43 ; 101 , 103 .

Ivanna and her husband are each starting a saving plan. Ivanna will initially set aside $50 and then add $50.85 every week to th
Olenka [21]

Answer:

N=0.019666a-0.983284 or

A = 50.85n + 50

Step-by-step explanation:

Let's solve for n.

a = 50 + 50.85n

Step 1: Flip the equation.

50.85n + 50 = a

Step 2: Add -50 to both sides.

50.85n+50+-50=a+-50

50.85n n = a - 50

Step 3: Divide both sides by 50.85.

50.85n

50.85

=

a-50

50.85

n=0.019666a-0.983284

Let's solve for a.

a = 50 + 50.85n
