Answer:
x = 47
Step-by-step explanation:
3x - 2 + 41 = 180 {Supplementary}
3x + 39 = 180
3x = 180 - 39
3x = 141
x = 141/3
x = 47

calculate the perimeter of a rectangle with length 4+5y-3x and width 2x - 8y
Answer: p = - 6y - 2x + 8
Step-by-step explanation:
p = 2l + 2w
p = 2(4+5y-3x) + 2(2x - 8y)
p = 8 + 10y - 6x + 4x- 16y
p = - 6y - 2x + 8
Answer:
P=-2x-6y+8 i believe
Step-by-step explanation:
P= 2(4+5y-3x) + 2(2x-8y)
P= 8+10y-6x +4x-16y
=8+10y+−6x+4x+−16y
=(−6x+4x)+(10y+−16y)+(8)
=−2x−6y+8

Answer:
V = 408 SA = 378
Step-by-step explanation:
To find the volume, you need to first find out the area and multiply it by overall length.
A = 1/2 (6)(8)
= 24
Volume = 24 x 17
= 408
Surface Area
SA = Front and Back + Right Side + Left Side + Bottom
= 2 [1/2 (6) (8)] + (17 x 10) + (3 x 8) + (17 x 8)
= 2 (24) + 170 + 24 + 136
= 48 + 170 + 24 + 136
= 378

Suppose the heights of the members of a population follow a normal
distribution. If the mean height of the population is 65 inches and the
standard deviation is 3 inches, 68% of the population will have a height within
which range?
A. 59 inches to 71 inches
B. 53 inches to 77 inches
C. 62 inches to 68 inches
D. 56 inches to 74 inches
Answer:
C; 62 to 68 inches
Step-by-step explanation:
Here, we want to get the population range that is having a probability of 68%
From the empirical rule, a measure of 1 standard deviation above the mean, with 1 standard deviation below the mean will give a total percentage of 68%
From the question;
1 standard deviation above the mean is 65 + 3 = 68
1 standard deviation below the mean is 65-3 = 62
so the range of the height of the population is 62 to 68 inches
In △ A B C , the measure of angle A is 103 ° and the measure of angle B is 37 ° . What is the measure of angle C ?
Step-by-step explanation:
103° + 37° + < C = 180° { being sum of angles of triangle }
< C = 180° - 140°
< C = 40°

The right triangle on the right is a scaled copy of the right triangle on the left. Identify the scale factor. Express your answer as a whole number or fraction in simplest form.
Answer:
One by third
Step-by-step explanation:
According to the figure the right angle triangle that was on left would be 3 times bigger than the right triangle that was on right. So here the dimension of the right triangle is one by third and equivalent to the dimension of the left triangle
the one on the left is 3 times larger than the one on the right. in other words, the right triangle's dimensions times 1/3 is equal to the left triangle's dimensions.

PLEASE ANSWER!! A prop for the theater club's play is constructed as a cone topped with a half-sphere. What is the volume of
the prop? Round your answer to the nearest tenth of a cubic inch. Use 3.14 to approximate pi. Complete
sentences
Answer:
Volume of prop = 706.5 in³
Step-by-step explanation:
Given:
Radius = 5 in
Height = 17 in
Find:
Volume of prop
Computation:
Volume of prop = Volume of cone + Volume of hemi-sphere
Volume of prop = 1/3(π)(r²)(h) + 2/3(π)(r)³
Volume of prop = 1/3(3.14)(5²)(17) + 2/3(3.14)(5)³
Volume of prop = 444.83 + 261.67
Volume of prop = 706.5 in³
