Step-by-step explanation:
Can someone please help with this? I am so confused
substitute a
-13 ; b = -9 ; C = 2 and evaluate each expression.
17. 2c + b - a + 14
18. -(-2a) + 16 - b2
19. -3b + C - a + 4
Answer:
Basically adding in and subing the letters with the numbers given too you below
Step-by-step explanation:
2(2)+(-9-13)+14= -4
-(-2(-13)+16-(-9)2= -60
-3(-9)+(2-13)+4= 48
Identify the volume of the composite figure. Round to the nearest tenth.
Answer:
474.5 ft ³
Step-by-step explanation:
1) Find the volume of the cube
[tex]A=l^3[/tex] where l is the side length
Plug in 9 ft as l
[tex]A=9^3\\A=729[/tex]
Therefore, the volume of the cube is 729 ft³.
2) Find the volume of the cylinder
[tex]A=\pi r^2h[/tex] where r is the radius of the base and h is the height of the cylinder
Plug in 3 ft as the radius and 9 as the height
[tex]A=\pi (3)^2(9)\\A=\pi (9)(9)\\A=81\pi \\A=254.5[/tex]
Therefore, the volume of the cylinder is approximately 254.5 ft ³.
3) Subtract the volume of the cylinder from the volume of the cube
729 ft³ - 254.5 ft ³
= 474.5 ft ³
Therefore, the volume of the figure is 474.5 ft ³.

Answer:
B) -5, 5, -7, 7
Step-by-step explanation:
3x² - bx + 2
factor:
(3x - 2 )(x - 1) = 3x² - (5)x + 2 so 5 does work
(3x - 1 )(x - 2) = 3x² - (7)x + 2 so 7 does work
(3x + 2 )(x + 1) = 3x² + 5x +2 = 3x² - (-5)x + 2 so -5 does work
(3x + 1 )(x + 2) = 3x² + 7x + 2 = 3x² - (-7)x + 2 so -7 does work

The total cost of a sweater and a pair of pants was $89.47. If the price of the sweater was $8.53 less than the pair of pants, what was the price of the sweater? Express your answer as a simplified fraction or a decimal rounded to two places.
Answer:
Let S = price of sweater
Let P = price of pants
S + P = 89.47 because that was the total spent
S = P - 8.53 because the sweater is 8.53 less than pants
Substitute P-8.53 in place of S in the
1st equation and solve for P
P - 8.53 + P = 89.47
2P - 8.53 = 89.47 add 8.53 to both sides
2P = 89.47 + 8.53
2P = 98.00 divide both sides by 2
P = 98.00/2
P = $49.00
S = P - 8.53
S = 49.00-8.53
S = $40.47
A sweater costs $40.47 and the pants cost $49.00
You estimate that there are 32 candies in a bag.
and find there are actually 29 candies. Find the percent error. Round to the
nearest tenth of a percent if necessary.
a. 0.09%
C. 9.4%
b. 0.10%
d. 10.3%
Answer:
D. 10.3%
Step-by-step explanation:
Find the percent error using the formula:
percent error = | (observed - expected) / expected | x 100
32 is the observed value, and 29 is the expected value
Plug in these values to solve for the percent error:
percent error = | (observed - expected) / expected | x 100
percent error = | (32 - 29) / 29 | x 100
percent error = 10.3%
So, the correct answer is D. 10.3%

What % of $30 is $21?
Answer:
70
Step-by-step explanation:
Answer:
x/100 x 30 = 21 (solve for x) x =70
I wish I could explain more but if your just lazy to do this i wont explain but if you honestly dont know I will explain, so solve for x you must multiply by a 100 on both sides and on the right side you multiply it to the fraction so x/100 x 100 = x (variable by itself means 1) then 21 x 100 = 21,000 therefore you are left with 30x since you are multiplying x and 30 together then you will divide by 30 on both sides to get x = 70

Answer:
2
Step-by-step explanation:
x/y equals to 6/3. Simplify it- 6(numerator) can go into 3(denominator) twice, so therefore it is 2.
Or you can divided 6(numerator) by 3(denominator), and get 2.
Hope this helped, guys!
