What is the total surface area??
Answer:
790 units^2
Step-by-step explanation:
Take the area of each side and add them all up. Remember each side is there twice.
Formula: SA = 2(15*5 + 15*16 + 5*16)
SA = 2(75 + 240 + 80)
SA = 2(395)
SA = 790

Consider the data shown on the graph.
• The y-intercept represents the base price of $ drag and drop answer here for airfare from NYC
• The slope represent a cost of drag and drop answer here cents per mile traveled.
• If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be drag and drop answer here
• If the cost per mile changed to 50 cents, the new equation would be drag and drop answer here
Answer:
Step-by-step explanation:
THE ANSWER IS 200 , 30, Y=50+0.30X, Y=200+ 0.50X
The solution is, x = 20, is the solution of Y=0.25x +50=0.30x+ 40.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
EXPLANATION
The equation given can be express as
y = 0.25x + 50
y = 0.30x + 40
Since, both equations are functions
Equate the two functions together
0.25x + 50 = 0.30x + 40
Collect the like terms
0.25x - 0.30x = 40 - 50
x(0.25 - 0.30) =-10
x(-0.5) = -10
-0.5x = -10
Divide both sides by -0.5
-0.5x / -0.5 = -10/-0.5
x = 10/0.5
x = 20
When collecting the like terms, we isolate values with the same variables from values with a different variables.
If a positive sign crosses an equality sign it automatically becomes a negative sign and if a negative sign crosses an equality operator it automatically becomes a positive sign.
Hence, The solution is, x = 20, is the solution of Y=0.25x +50=0.30x+ 40.

Which phrase describes the algebraic expression 7/8y-3
Answer:
Step 1: Remove parentheses by multiplying factors.
= (x * x) + (1 * x) + (2 * x) + (2 * 1)
Step 2: Combine like terms by adding coefficients.
(x * x) = x2
(1 * x) = 1x
(2* x) = 2x
Step 3: Combine the constants.
(2 * 1) = 2
Step 4: Therefore, Simplifying Algebraic Expression is solved as
= x2 + 3x + 2.

Answer:
Hopefully u will satisfy with my answer..!!Clarissa has a budget of $1,200 a month to spend for rent and food. She has already spent $928 this month. Which inequality represents the amount she can still spend this month and remain within her budget?
x greater-than 272
x less-than-or-equal-to 272
x less-than 272
x greater-than-or-equal-to 272
Answer:
1200-928 = 272 for the rest of the month Clarissa has to spend.
Step-by-step explanation:
So we don't want her to go over her budget so we wouldn't choose a greater than option for her so eliminate the first option and the last option. Now we just have the middle two. We want to keep it under 1200 but theres nothing wrong with spending that exact amount each month so I would pick x less than or equal to 272, since we can still equal the total of less than the total and not go over. Option 2 or B.

You deposit $5000 in an account earning 7.5% simple interest per year. How long will it take for the balance of the account to be $6500?
Answer:
4 years
Step-by-step explanation:
Given data
Principal P=$5000
Rate r= 7.5%
Final amount A=$6500
The expression for the simple interest is
A=P(1+rt)
Substitute
6500=5000(1+0.075*t)
6500=5000+375t
6500-5000=375t
1500=375t
t= 1500/375
t= 4 years
Hence, the time is 4 years

Oceanside Bike Rental Shop charges a 13 dollar fixed fee plus 9 dollars an
hour for renting a bike. Carlos paid 58 dollars to rent a bike. How many
hours did he pay to have the bike checked out? *
Answer: 5 hours
Step-by-step explanation:
Carl paid $58 dollars in total and this included the fixed dollar fee and the variable amount of $9.
To find the number of hours, first deduct the fixed component:
= 58 - 13
= $45
$45 was spent as a result of hourly fee. The number of hours is therefore:
= Total hourly cost/ Cost per hour
= 45 / 9
= 5 hours

What is an equation of the line that passes through the point ( − 1 , − 3 ) and is perpendicular to the line x − 2 y = 14? pls answer will mark you as brainiest
Answer:
y = -2x - 5
Step-by-step explanation:
First rewrite the second equation into y = mx + b format:
x - 2y = 14
2y = x - 14
y = x/2 - 14/2 (Divide both sides by 2)
y = 1/2x - 7
A line perpendicular to another has the negative reciprocal slope
So the slope of our first equation is -2. (Flip 1/2 = 2, then take the opposite)
Plug in the points (-1, -3) for the x and y coordinates.
x (x coordinate) = -1
y (y coordinate) = -3
slope (m) = -2
-3 = -1(-2) + b
-3 = 2 + b
-3 - 2 = b
b = -5
The equation of the line is y = -2x - 5. Hope this helps! :)
Answer:
y = -2x - 5 or 2x + y = -5
Step-by-step explanation:
Let's find the slope of the given line.
-2y = -x + 14
y = 1/2(x) -7
m = 1/2
The slope of a line perpendicular is the negative reciprocal of 1/2, which is -2
Now use the point-slope form of a line
y + 3 = -2(x + 1)
y + 3 = -2x - 2
y = -2x - 5 or 2x + y = -5

Answer:
C= 93⁰, B= 64⁰, D= 23⁰
Step-by-step explanation:
180= (4x + 1) + (3x - 5) + x⁰
180= 4x+1 +3x-5 +x
180= 8x - 4
184= 8x
184/8= x
23=x
therefore
C= (4(23) +1)
C= 93
B= (3(23)-5)
B= 64
D= 23
93⁰+64⁰+23⁰=180⁰
