19. A cross section of a water trough is in the shape of trapezoid with bases measuring 4 m and 12 m. what is the length of the
median of the trapezoid?
4
B. 6
C.8
D. 10
Given:
The bases of trapezoid measuring 4 m and 12 m.
To find:
The median of the trapezoid.
Solution:
The median of the trapezoid is the average of its bases.
[tex]\text{Median}=\dfrac{\text{Upper base + Lower base}}{2}[/tex]
The bases of trapezoid measuring 4 m and 12 m. So, the median of the trapezoid is:
[tex]\text{Median}=\dfrac{4+12}{2}[/tex]
[tex]\text{Median}=\dfrac{16}{2}[/tex]
[tex]\text{Median}=8[/tex]
Therefore, the correct option is C.

Find a point 1/5 of the way between points A (-6,-4) and B (-1,6).
9514 1404 393
Answer:
(-5, -2)
Step-by-step explanation:
That point P can be found from ...
P = A + 1/5(B -A)
P = (4/5)A +(1/5)B = (4A +B)/5
P = (4(-6, -4) +(-1, 6))/5 = (-24-1, -16+6)/5 = (-25, -10)/5
P = (-5, -2)
Answer:
the answer is (-5,-2)

or
x = 133°
Answer:
x = 133 degrees
Step-by-step explanation:
The 47 degrees is a corresponding angle with the angle on the right of x. Meaning that angle is also 47 degrees. After figuring that out, all you have to do is do subtraction (180-47=133) to get your answer.

Custodian at Movie Theater
pay:$9.95
per hours:
15.25 hours per week
How much do they make in
1) a- week
1 week = 15.25 hours
Hence,
1 hour = $9.95
15.25 hours = x
Cross Multiply
x = 15.25 × $9.95
x = $151.7375
Approximately = $151.74
2) A month
There are 4 weeks in a month
1 week = $151.74
4 weeks = x
Cross Multiply
x = 4 × $151.74
x = $606.96
3) A year
There are 52 weeks in a year
Hence,
1 week = $151.74
52 weeks = x
Cross Multiply
x = 52 × $151.74
x = $7890.48
Therefore, they made in :
1) A week: $151.74
2) A month : $606.96
3) A years : $7890.48

PLZZ HELP ME WITHTHSI
Answer:
c. 492 cubic centimetres
Step-by-step explanation:
the equation for the volume of a rectangular prism is
V = Length × Width × Height
we also have to take into account that there are 2 rectangular prisms in that picture so we have to add the volumes of both of them.
for the one on the bottom, the volume would be
V = 9 × 6 × 8
V = 432 cubic centimetres
now we'll do the one on the top
V = 3 × 5 × 4
V = 60 cubic centimetres
now we'll add up both volumes to get a total amount.
432 + 60 = 492 cubic centimetres

Which of the following is equivalent to the expression shown (0.2x-1)+(0.3-0.01x)
Answer:
0.07x - 0.002x^2 - 0.3
Step-by-step explanation:
Given the expression shown (0.2x-1)+(0.3-0.01x)
Expand
(0.2x-1)+(0.3-0.01x)
= 0.2x(0.3) - 0.2x(0.01x)-1(0.3) + 1(0.01x)
= 0.06x - 0.002x^2 - 0.3 + 0.01x
= 0.06x+0.01x - 0.002x^2 - 0.3
= 0.07x - 0.002x^2 - 0.3
This gives the required expression
