If u took a test that had 150 questions on it but didn’t finish 27 of the questions, what percentage of the questions did u answ

Alenkinab [10]

Answer:

82%

Step-by-step explanation:

Total number of questions = 150

Questions not answered = 27

questions answered = 150 - 27 = 123

percent questions answered

= (questions answered / total questions ) x 100%

= (123/150) x 100%

= 82%

Can someone help me with solving volume equations?

Helen [10]

Answer:

For 2, 30 cubic m., For 3, 90 cubic cm., For 4, 1000 cubic yards, for 5, 27 cubic mm., For 6, 120 cubic in.

Step-by-step explanation:

You can simply multiply all 3 sides to get the cubic volume B x h is the same as l x w x h

ex. Number 2, length 3, width 2, height 5

Base is 2x3=6 times 5 = 30 or 2 x 3 x 5=30

part 3. Find the coordinates of the vertices of the triangle after a reflection across the y-axis and then across the line y= 2.

garik1379 [7]

Answer:

c. S'(3, 1), T'(1, -1), U'(0, 1)

Step-by-step explanation:

Reflection across the y-axis negates the x-coordinate, so is equivalent to the transformation ...

(x, y) ⇒ (-x, y)

Reflection across the horizontal line y=c is equivalent to the transformation ...

(x, y) ⇒ (x, 2c-y)

So, the combined reflections are equivalent to the transformation ...

(x, y) ⇒ (-x, 4 -y)

Then we have ...

S(-3, 3) ⇒ S'(-(-3), 4-3) = S'(3, 1)

T(-1, 5) ⇒ T'(-(-1), 4-5) = T'(1, -1)

U(0, 3) ⇒ U'(-(0), 4-3) = U'(0, 1) . . . . matches choice C
