Answer:

4 mins more would be  taken by Ellina

Step-by-step explanation:

Given that

Jasleen answers 4 questions every 30 seconds

And, Ella answers 5 questions every 40 seconds

And, last week Jasleen took exactly 1 hour for answering a large set of questions

We need to find out the number of more minutes taken by Ella

As Jasleen answers four questions every 30 seconds

So, Jasleen answers  8 questions for every 1 minutes

Now

Jasleen answers time taken

=  60 × 8

= 480 questions for every 60 minutes  or 1hr

On the other hand

Ella answers five questions every 40 seconds.

So, 1 questions in 8 sec

Now for 480 Questions , it would take

= 480 × 8 secs

= 480  × 8  ÷ 60  min

= 8 × 8

= 64 mins

Hence 4 mins more would be  taken by Ellina

i just confused on what the triangular prisms volume is. i think i’m doing it correctly but online says something different.
DanielleElmas [232]

Answer:

The answer for just the triangular prism's volume is 175 inches cubed.

If you need me to add how to find the volume of the rectangular prism, please comment that you also need this then.

Step-by-step explanation:

A triangular prism's volume is equal to the base area (which is a triangle) multiplied by the length of the prism.

So find the area of the triangle and multiply it by 10 inches in this case.

So  they are going to try to confuse on the triangle here because of they give three measurements where one of them is unnecessary in the formula .5bh.

The b and h represent the base and height respectively. The base and height of a triangle when intersected form 90 degree angle.

So we are using the 5 inches and 7 inches for it's height and base respectively.

The 9 inches is unnecessary in the calculation.

The volume if the triangular prism is found by doing .5(7)(5) times 10. The answer is in inches cube since inches*inches*inches=inches cubed or in^3.

.5(7)(5)(10)

.5(10)(7)(5)

(5)(35)

175

The answer for just the triangular prism's volume is 175 inches cubed.

If you need me to add how to find the volume of the rectangular prism, please comment that you also need this then.

HELP! HELP! HELP! A function and its inverse are shown on the graph. Which answer pairs a possible domain restriction for f(x) a
Svetradugi [14.3K]

Answer:

  B. f(x) domain: x ≥ 1; f⁻¹(x) range: y ≥ 1

Step-by-step explanation:

The <em>domain</em> of a function is identical to the <em>range</em> of its inverse. This is reflected in choices B and D. However, f(x) is undefined for x < 1, so it makes no sense to restrict its domain to x ≤ -2, as in choice D.

The appropriate response is ...

  B.

  • f(x) domain: x ≥ 1
  • f⁻¹(x) range: y ≥ 1

Two parallel line segments move from Quadrant One to Quadrant Four. Their slopes does not change.
pishuonlain [190]

Answer:

B

Step-by-step explanation:

Dilation is changing it and it would not move Quadrants. Reflection would change the slope and I do not know if you can even do it from one to four (I also don't know which one is 1 and which one is 4).

All I know is that translation moves it without changing anything. It is a transformation bc it is translation.
