Question two is C. Question three is B

Answer:

For question 2, it is C) 3a.

For question 3, it is B) 3.

Step-by-step explanation:

For question 2, we are given that Mary's age is a and her mother's age is 3 times as old as Mary. The key word is "times" so this means that the expression can be written as 3a or 3 * a.

For question 3, the question asks for the greatest number that divides evenly into both 42 and 81. Using simple math, C and D automatically elliminates itself because one of the numbers divided gives a whole and the other gives a decimal. All is left is A and B. Obviously, a number divided by one will by itself so it stays even either way and the two numbers divided by 3 will give us two whole numbers and 3 is the greatest possible number so that concludes that it is B.

A carpenter's tool box is made up of nails, screws, washers, and brackets in a ratio of 4:11:9:6. The total number of the pieces in the box is 60. If 5 carpenters have identical tool boxes, how many total washers are in the boxes?
A. 18
B. 48
C. 62
D. 90

Answers

Answer: D 90

Step-by-step explanation:

One way to do this follows:  Find the ratio, r, which when multiplied by each of the four numbers in the ratio produces the actual number of parts present:

4r + 11r + 9r + 6r = 60

Summing these up results in 30r = 60, so r is 2.

There are 4(2), or 8, nails,

11(2), or 22, screws,

9(2), or 18, washers, and

6(2), or 12, brackets.

Note that 8 + 22 + 18 + 12 = 60 (total number of parts)

If 5 carpenters have identical boxes, there will be 5(18), or 90, total washers.

HELP PLEASEEE :) TY TYYYYY

Answers

Answer:

A = 8, B = 6, C = 4 , D = 7

Top = 29

Side = 20

Step-by-step explanation:

Last row : A + A + A + A = 32 ==> A = 8

First row : D + A + D + D = 3D + 8 = 29

                                          3D = 21 ==> D = 7

Second row : B + D + A + B = 27 ==> 2B + 7 + 8 = 27

                                                          2B = 12 ==> B = 6

Third column : D + A + C + A = 27

                      7 + 8 + C + 8  = 27 ==> C = 4

Answer:

As a decimal your answer: is 5.4 rounded to the nearest tenth. As a mixed number fraction your answer is: 5 11/25. As a improper fraction your answer is: 136/25.

Step-by-step explanation:

Basically what I did was just divide 6.8 by 4/5. Or you could change 4/5 in a decimal and divide like that, OR change 6.8 into a fraction which is what if did- I’ll show you below. But, it’s better to have all solutions to the problem.

1) change 6.8 into fraction: 34/5

2) rewrite: 34/5 divide by 4/5

3) multiply: 136/25

4) alternative forms:

A. Mixed number- 5 11/25

B. Decimal: 5.44 or 5.4 rounded to nearest tenth.

29 degrees

Using the knowledge of interior and exterior we know the angle Q is 124 because we have 56 degrees on the outside and it’s a supplementary angle so 180-56=124
Next, We know that the total of the interior angels should add up to 180 degrees so we add 124+ 27 and then get 151 degrees. Finally, we subtract 180-151= 29 degrees

Need help finding measurements on a rhombus

Answers

All of the measurements are the same because a rhombus is just a tilted square:
All sides are 4cm
Hope it helps ;)

Answer:

5. D  6. B   7. C

Step-by-step explanation:

All side lengths of a rhombus are the same therefore the length of WZ must be 4cm.

The sum of all the angles in a rhombus add up to 360 degrees, since we already have 2 100 degrees( opposite interior angles are the same) then the rest must be 80 degrees angles.
