What is the suface area of a rectangular prism that measures 2cm × 5cm × 8cm?
Answer: 132 hope that helps
Step-by-step explanation
Fastest way to do it A=2(wl+hl+hw)=2·(5·2+8·2+8·5)=132
Answer:
132 [tex]cm^{2}[/tex]
Step-by-step explanation:
A rectangular prism has 6 sides in total. We need to find the area of each side and add the areas together to find the total surface area.
Each side has an opposite that's parallel and on the opposite side of the prism, so there are 3 different sides whose areas are to be multiplied by 2.
First: let this side be SIDE A: 5 x 8 = 40 [tex]cm^{2}[/tex]
Second, let this side be SIDE B: 8 x 2 = 16 [tex]cm^{2}[/tex]
And thirdly, let this side be SIDE C: 2 x 5 = 10 [tex]cm^{2}[/tex]
These are the areas of 3 of the the sides of the prism. The other 3 are identical.
Now to find the Total SA, we add all of them together,
SA = 2 x (SIDE A) + 2 x (SIDE B) + 2 x (SIDE C).
= (2 x 40) + (2 x 16) + (2 x 10)
= 80 + 32 + 20
SA = 132 [tex]cm^{2}[/tex]

Tell whether x and y show direct variation x= (y-2)/(9)
PLEASE HELP I"LL MARK BRAINLIEST
EXPLAIN PLS
Answer:
not a direct variation
Step-by-step explanation:
x = (y-2)/9 is also x = y/9 - 2/9
we can convert this into slope-intercept form
y/9 = x + 2/9
y = 9x + 2
this equation is a straight line and is constantly going up BUT the y-intercept is not 0 so it is not a direct variation
the direct variation equation y = kx does not have a b or a y-intercept

Write the equation of line with slope of -3, passing through (-1,7) . write in slope -intercept form.
Hello there, hope you are having a nice day.
We are given the slope of the line and a point on the line, so we can write the equation in point-slope form:
y-7=-3(x-(-1)
y-7=-3(x+1)
y-7=-3x-3
Now, we move -7 to the right side, using the opposite operation:
y=-3x-3+7
y=-3x+4
This is the equation of our line. Hope it helps.
Ask me if you have any queries.

Minimum number of regions
You may have 100 parallel lines. This will give us 101 regions

find the value of x and y
Answer:
x = 60
y = 30
Step-by-step explanation:
We know that all triangles' interior angles combined must have a sum of 180.
Since the triangle on the left is a equilateral triangle, we know that each angle is equal to 60.
Since we already know that the sum of the two angles in the top right is 90 (shown by the right angle symbol) and we know that the angle that isn't y is equal to 60, we must do the following step:
90 - 60 = y
90 - 60 = 30
y = 30
Now that we know the value of y, it's time to find the value of x.
We know that y = 30 and that the angle in the bottom right is equal to 90 (shown by right angle symbol).
Since all triangles' interior angles combined must have a sum of 180 and we already know that one angle is equal to 30 and the other is equal to 90, we must do the following:
180 - (90 + y) = x
180 - (90 + 30) = x
180 - 120 = x
180 - 120 = 60
x = 60
This gives us the answers y = 30 and x = 60

Write the equation of a line that is parallel to the line y=−4x+1 and goes through the point (2,0).
Answer:
y=-4x+8
Step-by-step explanation:
Hi there!
We are given the line y=-4x+1, and we want to write the equation of the line that is parallel to that line and that also passes through the point (2, 0)
Parallel lines have the same slope, so it makes sense to find the slope of the line y=-4x+1
The line is written in the format y=mx+b, where m is the slope and b is the y intercept.
As -4 is in the place of where m should be, the slope of the line is -4.
It's also the slope of the line parallel to it.
We can write the slope of the new line in slope-intercept form as well; this is the line so far, after substituting -4 as m:
y=-4x+b
Now we need to find b, which is the value of the y intercept
Remember that are given the point (2,0), which we can use to help solve for b; substitute 2 as x and 0 as y.
0=-4(2)+b
Multiply
0=-8+b
Add 8 to both sides
8=b
Substitute 8 as b into the equation:
y=-4x+8
Hope this helps!
Can someone plz help I will mark Brainliest.
Answer: A( 148 meters )
Answer:
Choice A
Step-by-step explanation:
Using vertical angles, you know the side under the top 20 meters is also 24 meters. Then the most bottom side of the lower garden is 30 meters. You have 30+30+20+20+24+24=2(30)+2(20)+2(24)=2(30+20+24)=2(74)=148. Thus, choice is correct.

Kerry scored a total of 205 points last season by making
a total of 120 baskets. Some of the baskets were 1-point
free throws (t), and the rest were 2-point field goals (g).
Which pair of equations models this situation?
A.) t+2g=205
t+g=120
B.)t+g=205
t+2g=120
C.)t+g=205
t+g=120
D.)t+2g=205
t+2g=120
Answer:
a
Step-by-step explanation:
Answer:
A.) t+2g=205
t+g=120
Step-by-step explanation:
We know that Kerry scored 205 points by making 120 basket.
t+g=120 { Because some of the basket were 1-point free
t+2g= 205 ( Throws (t) and the rest were 2-point field goals (g)
