Answer:
-2
Step-by-step explanation:
Substitute 3 for m: (3)2 - 5(3) + 7
Simplify: 6 - 15 + 7
Follow PEMDAS and subtract 6 from 15: -9 + 7
Add: -2
Hope this helps ^-^
You said m = 3.
Replace every m you see with 3.
m^2 - 5m + 7
(3)^2 -5(3) + 7
9 - 15 + 7
-6 + 7 = 1

A formula for finding SA, the surface area of a rectangular prism, is
SA = 2(ab + ac + bc), where a, b, and c represent the lengths of the edges of the prism. What is the surface area of this prism if a = 12 inches, b = 6 inches, and c = 4 inches?
A.
B.
C.
D.
Step-by-step explanation:
SA=2*(12*6+12*4+6*4)
SA=2*(72+48+24)
SA=2*144
SA=288

The Sugar Sweet Company will choose from two companies to transport its sugar to market. The first company charges $6500 to rent trucks plus an additional fee of 175.25 for each ton of sugar. The second company charges $5696 to rent trucks plus an additional fee of 225.50 for each ton of sugar.
For what amount of sugar do the two companies charge the same?
What is the cost when the two companies charge the same?
Answer:
14 tons
$3,860.50
Step-by-step explanation:
Let x = the amount of sugar transported.
First company:
The cost is $3157 truck rental plus $50.25 per ton of sugar.
Total cost = 3157 + 50.25x dollars
Second company:
There is no charge for truck rental, but it costs $275.75 per ton of sugar.
The total cost is
275.75x
When the two costs are the same, then
275.75x = 3157 +50.25x
225.5x = 3157
x = 14 tons
The total cost is 275.75*14 = $3,860.50
Can someone please help me with math.
Answer:
9. C. 35 + 0.12x = 44.36
10. C. The system has no solution since the second equation is equal to 0
11. A. 32
Step-by-step explanation:
9. The Hill family drove for 78 miles
The rental agency chargers a weekend fee of $35.00 and 12 cents per mile
Convert cents to dollars
1 cent = 0.01 dollar
∴, 12 cent = 12 x 0.01 = 0.12 dollar
Therefore, total bill amount = 35 + 0.12 per mile
Let "x" be the number of miles driven
Final bill was $ 44.36
44.36 = 35 + 0.12x
0.12x = 44.36 - 35
0.12x = 9.36
Divide both sides of the equation by 0.12
x = 78
10. The system of equations is...
The true statement about the given system of equations.
The slope-intercept form of a line is...
Where m is the slope and b is the y-intercept.
We have,...
On comparing these two lines with slope-intercept form, we get...
Since the slopes of the lines are equal but the y-intercepts are different, therefore, the two lines are parallel and the system has no solution.
11. This is an equation Solutions: x=32.
⇒ Value of (Dimes + Quarters) = $ 6.70
or, (0.1 m) + 11.5 - 0.25 m = 6.70
-0.15 m = - 4.8
or, m = 4.8/0.15 = 32
⇒ m = 32

Which function produces an output of 5 for an input of -6?
A.f(x) = x + 1
B.f(x) = 2x + 4
C.f(x) = x - (-1)
D.f(x) = -x - 1
Answer:
The answer is D
Step-by-step explanation:
Since the input is -6, you input it into the equation. That would make it f(-6)=-(-6)-1 which would be equivalent to f(-6)=6-1 , as the negatives at the beginning of the equation cancel each other out and make it positive. Then you solve and get 5, which is your output. Hope I could help :)

The formula for the volume of a rectangular prism is V=l×w×h. Multiply the length times the width times the height to write a simplified expression in standard form to represent the volume of the box.
Answer:
Volume of box= Box Area * Box height
Step-by-step explanation:
If the box has equal sides then the l=w=h length is equal to height and both are equal to width so this can also be written as l=l=l or
Volume= length * width * height
V= l*w*h
V= l*l*l
V= l³
or if the three sides are not equal this can also be written as
Volume of box= Box length * Box width * Box height
If we observe closely we find that length * breadth gives the area so the volume of the box can also be written as
Volume of box= Box length * Box width * Box height
Volume of box= Box Area * Box height

The circumference of a redwood tree trunk is 20π ft, and it is 100 ft tall. What is the approximate volume of the redwood tree trunk?
1,000π ft3
10,000π ft3
4,000π ft3
40,000π ft3
9514 1404 393
Answer:
(b) 10,000π ft³
Step-by-step explanation:
The relation between circumference and radius is ...
C = 2πr
r = C/(2π) = (20π)/(2π) = 10 . . . . feet
The volume of a cylinder with radius 10 ft and height 100 ft is ...
V = πr²h
V = π(10 ft)²(100 ft)
V = 10,000π ft³
Answer:
10,000π ft3

689
No or Yes
Answer:
Yes
Step-by-step explanation:
6 + 8 = 14 which is bigger than 9 so it is possible
If the two shorter sides add up to a number that is equal to or smaller than the largest side, the triangle is impossible
