Find the surface area of a rectangular solid with the given dimensions: length 25 feet, width 7 feet, height 10 feet. Give your answer without units.
Answer: 990
Step-by-step explanation:
SA = 2LH + 2LW + 2WH
SA= 2(25•10) + 2(25•7) + 2(7•10)
SA= 990
The surface area of a rectangular solid will be 990 square feet.
What is the surface area of the rectangular prism?Let the prism with a length of L, a width of W, and a height of H. Then the surface area of the prism is given as
SA = 2(LW + WH + HL)
We have length 25 feet, width 7 feet, and height 10 feet.
SA = 2(25 x 7 + 7 x 10 + 10 x 25)
SA = 2(175 + 70 + 250)
SA = 2(495)
SA = 990 square feet

Answer:
y= (-4/1)x -1
Step-by-step explanation:
Point G is on line segment F H ‾ FH . Given F G = 5 x + 2 , FG=5x+2, G H = 3 x − 1 , GH=3x−1, and F H = 9 , FH=9, determine the numerical length of F G ‾ . FG .
Answer:
FG = 7
Step-by-step explanation:
From the question, we are given:
FG=5x+2, GH=3x−1, and F H = 9
FG + GH = FH
5x + 2 + 3x - 1 = 9
5x + 3x + 2 - 1 = 9
8x + 1 = 9
8x = 9 - 1
8x = 8
x = 8/8
x =1
We are determining the numerical length of FG
FG= 5x + 2
FG = 5(1) + 2
FG = 5 + 2
FG = 7

As a fundraiser for a band trip, the Edison Middle School Band plans to sell hats that feature the
school logo. The company producing the hats will charge the band $240 for the design and set-up
costs, plus $8 per hat. The band members have decided to sell the hats for $12 each.
a. Write an equation that represents the production cost in dollars to make the hats. Describe
what your variables represent.
b. Write an equation that represents the amount of money the band will make from selling the
hats. Describe at your variables represent
Answer:
a. c=240+8x
b. e=12x
Step-by-step explanation:
a. The equation would indicate that the production cost in dollars is equal to the design and set-up cost plus the cost per hat for the number of hats produced:
c=240+8x, where c is the production cost in dollars and x is the number of hats produced.
b. The equation would indicate that the amount of money the band will make from selling the hats is equal to the price per hat for the number of hats sold:
e=12x, where e is the amount of money the band will make from selling the hats and x is the number of hats sold.

Solve the system of equations.
2x + 3y = 1
5x + 2 = 8
What is the solution?
Answer:
x=6/5 ,y= -7/15
Step-by-step explanation:
we are going to solve this simultaneously.
2x+3y=1.......(i)
and
5x+2=8
5x=6
x= 6/5 .......(ii)
Now let's put value of x into equation number (i)
2x+3y=1
2(6/5) +3y=1
12/5 +3y =1
3y= 1-(12/5)
3y = -7/5
y = (-7/5) ÷3
y= -7/15

What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
We have to given that;
The quotient of 8 divided by one-third.
Now, We get;
The quotient of 8 divided by one-third.
⇒ 8 ÷ 1/3
⇒ 8 × 3
Thus, It is clear from the above steps that dividing 8 by 1/3 is equivalent to multiplying 8 by 3.

Garrison deposited $500 in an account that earns 5%
annual interest compounded annually. If he makes no
withdrawals or deposits, how much interest will the
account earn after 4 years?
Answer:
$107.75
Step-by-step explanation:
mark me brainliestt please
The Amount will be $607.75 and Interest is $ 107.75 after 4 years.
What is Compound Interest?In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one.
The interest you earn on interest is known as compound interest.
Given:
Garrison deposited $500.
Interest = 5%
Time= 4 years.
First, convert R as a percent to r as a decimal
r = R/100
r = 5/100
r = 0.05 rate per year,
Then solve the equation for A
A = P[tex](1 + r/n)^{nt[/tex]
A = 500.00[tex](1 + 0.05/1)^{(1)(4)[/tex]
A = 500.00[tex](1 + 0.05)^{(4)[/tex]
A = $607.75
and, I = A- P
I = 607. 75 - 500
I= $107.5

Given a normal distribution with a mean of 125 and a standard deviation of 14, what percentage of values is within the interval 111 to 139?
A. 32%
B. 50%
C. 68%
D. 95%
E. 99.7%
Answer:68%
Step-by-step explanation:
just took this test
The percentage of values is within the interval 111 to 139 will be "68%".
ProbabilityAccording to the question,
Mean = 125
Standard deviation = 14
Let,
The random variable be "X".
Now, the probability:
→ P(111 < X < 139) = P (111 - 125 < X - 125 < 139 - 125)
= P(-14 < X - 125 < 14)
= P(-[tex]\frac{14}{14}[/tex] < [tex]\frac{(X-125)}{14}[/tex] < [tex]\frac{14}{14}[/tex])
= P(-1 < Z < 1)
When, Distribution function "[tex]\phi[/tex]" now,
= [tex]\phi[/tex](1) - [tex]\phi[/tex](-1)
= [tex]\phi[/tex](1) - 1 + [tex]\phi[/tex](1)
= 2 × [tex]\phi[/tex](1) - 1
= 2 × 0.8413 -1
= 1.6826 - 1
= 0.6826 or,
= 68%
Thus the above answer i.e., "option C" is correct.
