Answer:

The answer is 6 (A)

Step-by-step explanation:

The exact answer is 5.73, but I think in the question they are rounding to the nearest whole number, so the rounded answer is 6.

My work:

C = 2πr

r = C

2π = 36

2·π = 5.72958

Answer:

Fifth Score = 87

Sixth Score = 95

Step-by-step explanation:

Given

$Average = 85$

$Scores = 83, 78, 87, 80$

$Fifth\ score = x$

$Sixth\ Score = 8 + x$

Required

Set up an equation

Solve for the fifth and sixth score

Average is calculated as thus:

$Average = \frac{\sum x}{n}$

$Average = \frac{83 +78 + 87 + 80 + x + 8 + x}{6}$

Substitute 85 for Average

$85 = \frac{83 +78 + 87 + 80 + x + 8 + x}{6}$

$85 = \frac{83 +78 + 87 + 80 + 8+ x + x}{6}$

$85 = \frac{336+ 2x}{6}$

Multiply both sides by 6

$85 * 6 = 336 + 2x$

$510= 336 + 2x$

Solve for 2x

$2x = 510 - 336$

$2x = 174$

Solve for x

$x = 174/2$

$x = 87$

Hence:

$Fifth\ Score = 87$

$Sixth\ Score = 87 + 8$

$Sixth\ Score = 95$

X≤−2 and x<−5 on a number line

sweet [91]

x is less than or equal to -2.

x is greater than -5.

When x is less than something, the arrow must go left. <———

When x is equal to a number, the dot must be filled in. •

When x is greater than a number, the arrow should go right, toward the greater values. ——>

When x isn’t equal to the number, the circle is not colored in. ⭕️
