T is to 9 as 7 is to 39

Answers

Answer 1
Answer:

Answer:

T = 21/13

Step-by-step explanation:

Step 1:  Make an expression

T is to 9 as 7 is to 39

(T)/(9) = (7)/(39)

Step 2:  Cross multiply

(T)/(9) = (7)/(39)

39(T) = 7(9)

39t = 63

Step 3:  Divide both sides by 39

39T / 39 = 63 / 39

T = 21 / 13

Answer:  T = 21/13

Find the 9th term

Answers

Answer:

The ninth term would 0.25.

Step-by-step explanation:

The pattern happening here is that the number is being divided by 2.

So, continuing the pattern, continue dividing by 2.

8÷2= 4   ----> 5th term

4÷2= 2   ----> 6th term

2÷2= 1    ----> 7th term

1÷2= 0.5 ----> 8th term

0.5÷2= 0,25 ---> 9th term

PLEASE DONT SKIPDavid has a hose that is 27 ft long. He wants to cut it into two pieces so that the longer piece is 3 ft more than 2 times the length of the shorter piece.



How long will each piece of hose be?



Shorter piece: ft

Longer piece: ft

Answers

To find this, first we subtract the extra 3 feet from the original 27 feet.
27-3=24
Then, we divide the left over length by three. This will provide us with the length for the shorter piece.
24/3=8
The shorter piece will be 8 feet long.
Now, we double that to find the longer piece without the additional 3 feet.
8x2=16
And we add those two (8 and 16) together to make sure it is equal to the 24 we divided into 3 earlier.
16+8=24
Now all that's left is to add the extra 3 feet to the 16 feet.
16+3=19
And add that to the 8 feet, to check to make sure the lengths add up to our original 27 feet.
19+8=27
Therefore, the two pieces are the following lengths:
Shorter piece: 8 feet
Longer piece: 19 feet

Answer:

Shorter piece: 8ft

Longer piece: 19ft

What is the area of the rectangle? Round to the nearest square inch.A.
27 in2

B.
31 in2

C.
45 in2

D.
47 in2

Answers

The area of a rectangle is expressed the product of its length and its width. For this rectangle we are given only its width and its diagonal. Thus, we need to solve for its length. A diagonal is a line that divides the rectangle making two right triangles. We can solve its length by using the diagonal. Calculations are as follows:

cos 45 = Length / 8
Length = 4√2 in

Area = (4√2)(5) = 20√2 in
