Answer:
x = 3
Step-by-step explanation:
3(2 - 4x) = -30
=>6 - 12x = -30
=> 12x = 36
=> x = 3
Suppose U = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 } is the universal set and Q = { 3, 6, 9 }. What is Q?
mr_godi [17]
The answer for this is
3. Suppose U = { 1,2,3,4,5,6,7,8,9,10} is the universal set ans Q = {3,6,9}. What is Q's? (1 point)
A{3,6,9}
B{4,5,7,8}
C{1,2,4,5,7,8,10}
D{1,2,3,4,5,6,7,8,9,10}
C. - {1,2,4,5,7,8,10}
For question 4 and 5, suppose U = {1,2,3,4,5,6,7,8}, A = (1,3,5,7), and B = {4,5,6}. Tell whether each statement is true or false.
4. A <span>⊆ B (1 point)
True
False
B. Ture
5. B </span><span>⊆ <u /> U (1 point)
True
False
A. True</span>
Answer:
A) 283500 ft³
B) 1057.26 π in³
Step-by-step explanation:
A) Volume of square based pyramid
= 1/3 × Area of the base × height
= 1/3 × (90 ft)² × 105 ft
= 283500 ft³
B) This figure is a composite figure
Step 1
Find the volume of the cone
=1/3 πr²h
r = radius = 8.5 in
h = height = 10 in
= 1/3 × π × (8.5 in)² × 10 in
= 240.83333333 π in³
≈ 240.83 π in³
Step 2
Find the volume of the cylinder
= πr²h
= r = radius = 8.5 in
h = height = 11.3 in
= π × (8.5 in)² × 11.3 in
= 816.425 π in³
≈ 816.43π in³
Volume of the figure = (240.83 π + 816.43 π) in³
= 1057.26 π in³
c. 35 sq. units
how you get that is you multiply
5 x 14 = 70
then divide by 2
70 divided by 2 = 35
formula
base x height divided by 2 = area of triangle (remember to square it also)
21/22
use y2-y1 / x2-x1
(9-(-12)) / (3-(-19))
21/22
