i hope this helped, please mark Brainliest, thank you!!
Answer:
6.3
Step-by-step explanation:
Arc length is circumference
C = 2 * pi *r
We are finding a fraction of the total arc length
A circle is 360 degrees
45 degrees / 360 degrees = 1/8
Find the total arc length and multiply by the fraction of the circle
arc length = 2 * pi * r * 1/8
= 2 * 3.14 * 8 * 1/8
=6.28
Rounding to the nearest tenth
6.3
<u>Solution</u><u> </u><u>1</u><u> </u><u>:</u><u>-</u>
>> -3 (3 - x) = 2x + 5
>> -3 × (3 - x) = 2x + 5
>> -9 + 3x = 2x + 5
>> 3x - 2x = 9 + 5
>> x = 14
<u>Solution</u><u> </u><u>2</u><u> </u><u>:</u><u>-</u>
>> -6 - 9p = 3p
>> -9p - 3p = 6
>> -12p = 6
>> p = -1/2
<u>Solution</u><u> </u><u>3</u><u> </u><u>:</u><u>-</u>
>> -5 (-4 - a) = 3a + 8
>> -5 × (-4 - a) = 3a + 8
>> 20 + 5a = 3a + 8
>> 5a - 3a = 8 - 20
>> 2a = -12
>> a = -12 / 2
>> a = -6
<u>Solution</u><u> </u><u>4</u><u> </u><u>:</u><u>-</u>
>> s - 6 = -5s
>> s + 5s = 6
>> 6s = 6
>> s = 6 / 6
>> s = 1
Answer:
the going to be answer A
Step-by-step explanation:
because the rhombus is moved down 2 and over 6 and was dilated by 2
4 1/2 cups = 9/2 cups
9/2 / 1/3=
9/2 * 3/1 = 27/2 = 13 1/2 servings at 1/3 cup each
