Answer:
Volume of the shape = 1,190 in.³
Step-by-step explanation:
The volume of the shape = volume of the rectangular prism - volume of the right triangle prism
= L*W*H - ½*b*h*l
Where,
L = 20 in.
W = 8 in.
H = 8 in.
b = 3 in.
h = 3 in.
l = 20 in.
Plug in the values
Volume of the shape = 20*8*8 - ½*3*3*20
= 1,280 - 90
= 1,190 in.³

On a math test, students
earn 4 points for each correct answer and lose 1 point
for each incorrect answer. If there are 50 questions on
the test, a student's score is shown by the expression
4(50 - w) - w, where w is the number of wrong

A student usually saves $20 a month. He would like to reach a goal of saving $350 in 12 months. The student writes the equation
350 = 12(x + 20) to represent this situation. Solve the equation for x.
• Show your work or explain your answer.
Write your answer as a sentence that describes what the variable x represents.
Answer:
Step-by-step explanation:
350=12(x+20)
(divide both sides by 12)
29.1667=x+20
(subtract 20 from both sides)
x=9.16667
X (9.17) is the additional amount of money the student must save each month in order to reach his goal.

I need help with Algebra 2. Thank you! :)
Answer:
B: 6.0
Step-by-step explanation:
-3t^2+9t+54 = 0
This is the equation that needs to be solved
Divide both sides by -3
t^2 - 3t - 18 = 0
The factors of 18 are: (1 18) (2 9) (3 6)
3 - 6 = -3 and 3 x -6 = -18
So: (t + 3) (t - 6) = 0
t = -3, 6
It can't be negative so the answer is 6

Step-by-step explanation:
Use differentials to estimate the amount of material in a closed cylindrical can that is 60 cm high and 24 cm in diameter if the metal in the top and bottom is 0.1 cm thick, and the metal in the sides is 0.05 cm thick. Note, you are approximating the volume of metal which makes up the can (i.e. melt the can into a blob and measure its volume), not the volume it encloses. The differential for the volume is
Answer:
dV ≈ 927.4 cm³
Step-by-step explanation:
Formula for volume of a cylinder is;
V = πr²h
Using differentials, we have;
dV = (dV/dr)dr + (dV/dh)dh
Now, dV/dr = 2πrh
dV/dh = πr²
Thus, at r = 24/2 = 12 cm
And at h = 60 cm, we have;
dV/dr = 2π(12 × 60)
dV/dr = 4523.89 cm²
Also;
dV/dh = π(12)²
dV/dh = 452.39 cm²
the metal in the top and bottom is 0.1 cm thick. Thus, dr = 2 × 0.1 = 0.2
the metal in the sides is 0.05 cm thick. Thus; dh = 0.05
Thus;
dV = (4523.89 × 0.2) + (452.39 × 0.05)
dV ≈ 927.4 cm³

A shelf is built on a wall, as shown below. What is the value of x?
(2x+1) + (3x-1)
Answer:
x = 18
Step-by-step explanation:
We need to find the value of x.
We know that the sum of angles of a triangle is equal to 180°. So, using this property,
2x+1+3x-1+90 = 180
2x+3x = 180-90
5x = 90
x = 18
So, the value of x is equal to 18.

The price of XYZ stock fluctuates widely. In January it closed at $3.50 but In February it Closed at $2.25. However at the end of March it shot back up to $5.00.
What was the average monthy change in the price of XYZ stock from january through march?
Answer:
$3.583
Step-by-step explanation:
Given the monthly stock prices :
January = $3.50
February = $2.25
March = $5.00
The average monthly change in price of XYZ stock from. JANUARY through MARCH is;
(January + February + March) / 3
Average monthly change :
(3.50 + 2.25 + 5.00) / 3
$10.75 / 3
= $3.583

Step-by-step explanation:
Given the summary output :
_______ Coeff___ StdError__ t-stat
Intercept 1283.000_ 352.000 _ 3.65
X1 _____ 25.228 ____8.631

General form of a multiple regression model:
Y = B1X1+B2X2 +E
The fitted regression equation is :
y = 25.228X1 + 0.861X2 + 1283
Intercept and slope corresponding to the standard error :
Intercept = 352
Slope 1 = 8.61 ; slope 2 = 0.372
