Question 5 of 10
musickatia [10]

Answer:

25 in ^2

Step-by-step explanation:

First find the area of the circle

A = pi r^2

A = 3.14 ( 4.3)^2

A =58.0586

The take the fraction of the circle that is shaded

A circle is 360 degrees

155/360

155 /360 * the  total area = area shaded

31/72 * 58.0586 = 24.99745278 in ^2

Rounding yields 25 in ^2

Find the measure of angle b if angle a is 22 degrees and the whole angle is 300 degrees
Dima020 [189]

Answer:

a  = 278^{\circ}

Step-by-step explanation:

Given

b = 22^{\circ}

Whole\ Angle = 300^{\circ}

Required

Find the measure of a

Since there is no diagram to support the question, we'll assume that:

a + b = Whole\ Angle

This gives:

a + 22^{\circ} = 300^{\circ}

Subtract 22 from both sides

a + 22^{\circ}-22^{\circ} = 300^{\circ}-22^{\circ}

a  = 300^{\circ}-22^{\circ}

a  = 278^{\circ}

Find the number of integral solutions of x+y +z = 12, where −3 ≤ x ≤ 4, 2 ≤ y ≤ 11, and<br> z ≥ 3.
SashulF [63]

There are 59 integer solutions

Such questions are best solved by writing cases and calculating the total number of cases. So beginning with

1)  x = -3. The possible combinations are as follows:-

-3 2 13

-3 3 12

-3 4 11

-3 5 10

-3 6 9

-3 7 8

-3 8 7

-3 9 6

-3 10 5

-3 11 4

10 combinations

2) x = -2

-2 2 12

through

-2 11 3

10 combinations

3) x = -1

-1 2 11

through

-1 10 3

9 combinations

4) x = 0

0 2 10

through

0 9 3

8 combinations

as we can see from the pattern at x =1  we get 7 combinations, at x =2  we get 6 combinations, at x=3 we get 5 combinations and at x =4  we get 5 combinations.

Thus total number of combinations 4+5+6+7+8+9+10+10 = 59 integer solution.
