Answer:
9) 3.7 in
10) 12 in²
11) 18 in³
12) V=432π cm³
TSA= 216π cm²
13)V=448π ft³
TSA=240π ft²
Step-by-step explanation:
9) Since all side of the trapezium are the same the height = perpendicular line which is 3.7 in
10) 3×4 (the quadrilateral at the bottom)
11)∵ A= Cross-sectional area× height
⇒A= Area of the trapezium × 4
∴ A=[tex]\frac{1}{2} \\[/tex] (sum of the parallel sides) × 4
A=[tex]\frac{1}{2} \\[/tex] (3+6) × 4
A= 18 in²
12) V=πr²h
V=π(6)²(12)
⇒V=432 cm³
TSA=2(πr²)+2πrh
TSA=2(π(6)²)+2π(6)(12)
⇒TSA=240π cm²
13. V=πr²h
V=π(8)²(7)
V=448π ft³
TSA=2(πr²)+2πrh
TSA=2(π(8)²)+2π(8)(7)
TSA=240π ft²
9) 3.7 in
10) 12 in²
11) 18 in³
12) V=432π cm³
TSA= 216π cm²
13)V=448π ft³
TSA=240π ft²

How was ice able to fall even though the temperature was much warmer than freezing?
a) Ja’quan read the thermometer wrong
b) He must have observed hail falling from thunder clouds
c) It was cold enough to allow solid precipitation to fall
d) Children were most likely throwing ice

Select the correct function. Select the function with an average rate of change of 3 over the interval [1, 3].
Answer:
Function g(x)
Step-by-step explanation:
Given
See attachment for functions
Required
Which has an average rate of 3 over [1,3]
The average rate of change (m) is calculated as:
[tex]m = \frac{f(b) - f(a)}{b -a}[/tex]
Where:
[tex][a,b] = [1,3][/tex]
So, we have:
[tex]m = \frac{f(3) - f(1)}{3 -1}[/tex]
[tex]m = \frac{f(3) - f(1)}{2}[/tex]
From the table f(x), we have:
[tex]f(3) = 6\\ f(1) = -2[/tex]
So:
[tex]m = \frac{6 - -2}{2}[/tex]
[tex]m = \frac{8}{2}[/tex]
[tex]m =4[/tex]
From the graph of g(x), we have:
[tex]g(3) = 4\\ g(1) = -2[/tex]
So:
[tex]m = \frac{g(3) - g(1)}{2}[/tex]
[tex]m = \frac{4 - -2}{2}[/tex]
[tex]m = \frac{6}{2}[/tex]
[tex]m =3[/tex]
Since only one of the function has an average rate of change of 3 over the given interval,
Then g(x) answers the question

in the diagram below, the measure of angle W is 5 times as large as the measure of angle X. what is the measure of angle W?
Answer:
D. 150°
Step-by-step explanation:
∠X and ∠W are supplementary
Let a = m∠X
Then 5a = m∠W
m∠X + m∠W = 180
a + 5a = 180
6a = 180
a = 30
m∠W = 5a = 5(30) = 150°

The ratio of boys to girls in the 10th grade is 8 to 13. If there are 91 girls in 10th grade, then how many boys are there?
Answer: There are 56 boys in the 10th grade
Step-by-step explanation:
Step 1
ratio of boys to girls in the 10th grade is 8 :13
Number of girls= 91
To find the number of boys, we first find the total number of boys and girls in the 10th grade
Step 2
Now the total ratio= 8 +13=21
Number of girls = ratio of girls/ total ratio x Total number of students
91=13/ 21 x Total number of students
Total number of students =21 x 91 / 13 =147
Step 3
Therefore Number of boys =ratio of boys/ total ratio x Total number of student
8/21 x 147=56

The high temperatures for the last seven days are: High Temperatures: 81, 78, 83, 89, 80, 87, 78
Find the MEAN of the temperatures. Round to the nearest tenths place.
A. 82.3
B. 89
C. 83
D. 78
Answer:
Mean of temperatures = 82.3 (Approx.)
Step-by-step explanation:
Given:
Number of days = 7 days
Temperatures in 7 days = 81, 78, 83, 89, 80, 87, 78
Find;
Mean of temperatures
Computation:
Mean = Sum of all observation / Number of observation
Mean of temperatures = Sum of all seven days temperature / Number of days
Mean of temperatures = [81 + 78 + 83 + 89 + 80 + 87 + 78] / 7
Mean of temperatures = 576 / 7
Mean of temperatures = 82.2857
Mean of temperatures = 82.3 (Approx.)
Megan's age is three years more than four times her daughter's age. If Megan's daughter's age is $d$ , Megan's age is
Answer: 4d + 3
Step-by-step explanation:
Megan's daughter's age = d
Based on the information given, since Megan's age is three years more than four times her daughter's age, this can be written mathematically as:
= (4 × d) + 3
= 4d + 3
Therefore, Megan's age is 4d + 3.
For example, if the daughters age is 7 years, Megan's age will be:
= 4d + 3
= 4(7) + 3
= 28 + 3
= 31 years

factorise x squared - 3x
Answer:
x squared -3× =x(x-3)
Step-by-step explanation:
Since the common factor is x,one comes out to multiply the other to give it x squared and since one x has been written outside already we just write the 3 so that when we multiply it we will get the answer we were asked to factorise

WILL REWARD BRAINIEST! What is the volume of the composite figure if both the height and the diameter of the cylinder are 10.5 feet? Give the exact answer and approximate to two decimal places.
Answer:
908.74
Step-by-step explanation:
The formula for the volume of a cylinder is V = h * pi * r^2
h is height, r is radius, and pi is 3.14. The radius is half of the diameter, so that would make the radius 5.25.
So now plug it into the formula:
V = 10.5 * pi * (5.25)^2
= 908.74
Hope this helped! :)
Answer:
1211.65 cubed ft.
Step-by-step explanation:
Half sphere: V = 4/3(3.24)(5.25^3)
V = 605.82
Divide by two since we need to find the volume of the half sphere, not the full sphere.
605.82 ÷ 2 = 302.91
Cylinder: V = (3.14)(5.25^2)(10.5)
V = 908.74
Add the two volumes to each other to find the total volume of the composite figure.
908.74 + 302.91 = 1211.65

A circular flower bed is 17m in diameter and has a circular sidewalk around it that is 2m wide. Find the area of the sidewalk in square meters. Use 3.14 for (pie sign).
The area of the sidewalk is (insert answer) m(squared)
(Round to the nearest whole number as needed.)
Answer:53.38 is the answer
Step-by-step explanation:
The radius is always half of the diameter so half of 17 is 8.5. 8.5x3.14 is 26.69. Then you add 26.69+26.69 to get the answer. (I’m not positive that this is correct)
