Answer:
Area of shaded part = 113 mm² (Approx.)
Step-by-step explanation:
Given:
Diameter of Semi-circle = 24 mm
Find:
Area of shaded part
Computation:
Radius of semi-cicrle = Diameter of Semi-circle / 2
Radius of semi-cicrle = 24 / 2
Radius of semi-cicrle = 12 mm
So,
Radius of small circle = 12 / 2
Radius of small circle = 6 mm
Area of shaded part = Area of semi circle - Area of small circle
Area of shaded part = [πR² / 2] - [πr²]
Area of shaded part = [(3.14)(12)² / 2] - [(3.14)(6)²]
Area of shaded part = [(3.14)(144) / 2] - [(3.14)(36)]
Area of shaded part = 226.08 - 113.04
Area of shaded part = 113.04
Area of shaded part = 113 mm² (Approx.)

Find the equation of the linear relationship.
Answer:
y = -3x + 150
Step-by-step explanation:
2 points on the graph:
(30, 60) and (40, 30)
Slope:
m=(y2-y1)/(x2-x1)
m=(30 - 60)/(40 - 30)
m= (-30)/10
m= -3
Slope-intercept:
y - y1 = m(x - x1)
y - 60 = -3(x - 30)
y - 60 = -3x + 90
y = -3x + 150
in. in What is the area of this trapezoid? b2 = 5 in. h = 4 in. 3 in. 2 in. b1 = 10 in.
Answer:
30 square inches
Step-by-step explanation:
The equation for the area of a trapezoid is: (b1 + b2) x h) / 2
(10 + 5) x 4) /2
15 x 4 = 60
60/2 = 30

(16x-2)
x=
Answer:
x = 9
Step-by-step explanation:
m<K = 71°
arc JL = 16x - 2
m<k = ½(arc JL) => inscribed angles theorem
Substitute
71 = ½(16x - 2)
Multiply both sides by 2
71*2 = 16x - 2
142 = 16x - 2
Add 2 to both sides
142 + 2 = 16x - 2 + 2
144 = 16x
Divide both sides by 16
144/16 = 16x/16
9 = x
x = 9

Hello I need this quickly pls
Answer:
Area = x² + 10x + 21
Step-by-step explanation:
Area = L * W
Length = (x + 7)
Width = (x + 3)
=> Area = (x + 7) * (x + 3)
=> Area = x² + 3x + 7x + 21
Combining like terms would result in;
=> Area = x² + 10x + 21

composite figure help omg
Answer:
188 sq m
Step-by-step explanation:
for the top square its just 6 x 6 which is 36
then for the bottom you add 6 + 13 for the width (which is 19) and we've already been given 8 for the height so then you multiply 19 x 8 and get 152
you then add 152 and 36 to get 188 (and the unit is sq m or m^2)

Right triangles have the measure of one of its angles to be 90 degrees
The ratio WY/WX is 0.36
From the triangle (see attachment), one of the angles of triangle WXY is 70 degrees.
This means that, the triangle is similar to triangle 1.
Similar triangles may or may not have congruent side lengthsSimilar triangles have equivalent ratiosSo, by comparing the side lengths, we have:
[tex]WY = 3.4[/tex]
[tex]WX = 9.4[/tex]
The ratio is then calculated as:
[tex]\frac{WY}{WX}= \frac{3.4}{9.4}[/tex]
[tex]\frac{WY}{WX}= 0.36[/tex]
Hence, the ratio WY/WX is 0.36

According to the Centers for Disease control and prevention, 20.8 of high school students currently use electronic cigarettes. A high school counselor is concerned that the use of e-cigs at her school is higher.
(a) Determine the null and alternative hypotheses.
(b) If the sample data indicate that the null hypothesis should not be rejected, state the conclusion of the school counselor.
(c) Suppose, in fact, that the proportion of students at the counselor's high school who use electronic cigarettes is 0.034. Was a Type I or Type II error committed?
Answer:
H0 : p = 0.028
H1: p > 0.028
We conclude that there is not enough evidence to support the school counselor's claim they the use of electronic cigarettes in high school is higher Than 2.8%
Type 11 error
Step-by-step explanation:
H0 : p = 0.028
H1: p > 0.028
If null should not be rejected then;
We conclude that there is not enough evidence to support the school counselor's claim they the use of electronic cigarettes in high school is higher Than 2.8%
3.)
If the actual proportion is 0.034, which means 3.4%, this means it is actually higher. For failing to reject a false Null, then a type 11 error has been committed

65% of her collection consists of gold coins.
70 of her coins are silver.
What is the total number of coins in Sonya's collection?
Enter your answer in the space provided.
HELP PLEASE
Answer:
10.5
Step-by-step explanation:
65% of 70 is 45.5
So gold is 45.5 and silver is 54.5
so but45.5 + 54.5 = 100% but divide by 2
which is 50% but now we find 10% and 5%
10% = 7
5% = 3.5
now add 7 and 3.5 together
7+3.5 = 10.5
