Answer:

r = 6

Step-by-step explanation:

Hello!

-8 - 2(7r + 1) = -94

Add 8 to both sides

-2(7r + 1) = -86

Divide both sides by -2

7r + 1 = 43

Subtract 1 from both sides

7r = 42

Divide both sides by 7

r = 6

Hope this Helps

Please can someone please help me
antoniya [11.8K]

Answer:

544 cm²

Step-by-step explanation:

hello,

to find the tsa of a rectangular prism, you use:

tsa = 2 ( lw + lh + wh )

in this case, l = 16 cm, w = 6 cm and h = 8 cm.

knowing these informations, you can proceed with using the formula.

tsa = 2 [ ( 16*6) + ( 16*8 ) + ( 6*8) ]

= 2 [ 96 + 128 + 48 ]

= 2 ( 272 )

= 544 cm²

please try to understand how i worked this out, and do let me know if you have any questions.

have a great day! thank you!

Name:
Elanso [62]

The sequences that would map the triangles so as to support both claims are explained below:

<em>Transformation</em> is a process in which the dimensions, size or orientation of a given shape is <em>adjusted</em>. The types are: translation, reflection, rotation and dilation.

Thus;

A. The sequence of transformations that will <u>support</u> Tim's thinking are:

i. <em>Reflection</em> of triangle A <em>about</em> the y-axis.

ii. <em>Reflection</em> of the triangle the <em>second</em> time now about x-axis.

iii. <em>Translation</em> of the triangle two units to the right (i.e towards the x-axis)

These steps would map triangle A unto triangle B supporting Tim's claim.

B. The sequence of transformations that will <u>support</u> Jennifer's claim are:

i. First <em>rotate</em> triangle A by 180^{o} using the origin of the axis as the reference point.

ii. Then <em>translate</em> triangle A two units to the right (i.e towards the x-axis).

Therefore, these steps will map triangle A unto B to support Jennifer's claim.

SOMEBODY PLEASE GIVE ME THE ANSWERS TO QUESTION 5,6, AND 7. I REALLY NEED YOUR HELP AND I CAN'T GET BAD GRADES!! ;(
sveticcg [70]

Answer:

Step-by-step explanation:

5. The problem gives us that the dollar value of the quarters we have is v, and the number of quarters we have is n. So basically, for example, if n was 8 then v would be 2 because there are 4 quarters in every dollar, so 8 quarters would be 2 dollars. Thus, to find how many dollars in the amount of quarters you have, you must divide by 4. Therefore, the equation would be v = 1/4n.

6. To be honest, I don't know what number 6 is asking. It's asking for Output $, but to find the output, you must have an input, but the problem doesn't give you one. It might be cropped out so, if the problem gives you an input (in this case, n quarters), you divide it by 4 and that will be your answer to 6. (ie. the problem gives you 12 as the input. Answer would be 3 because 12 quarters = 3 dollars).

If it doesn't give you the input, then I believe it would be 0.25 because each quarter is 0.25 of a dollar. I believe it should have an input number though, because it doesn't make any sense to me.

7. The independent variable is the thing you are changing, or the input. Since the number of the quarters is the input and not the VALUE of the quarters, it is false.
