In a rectangle, the perimeter is 102 inches. The width of the rectangle is 9 inch more than half thelength. What are the length and width of the rectangle?

Answers

Answer 1

Answer:

perimeter = 2width + 2 length

102 = 2(x+9) + 2x

102 = 2x + 18 +2x

102 = 4x +18

84 = 4x

21 = x

Length = x = 21 inches

Width = x + 9 = 21 + 9 = 30 inches

A trumpet vine is currently 16 inches tall planted next to a 4-foot fence. the trumpet vine grows at an average rate of 1/2 inch per day. at that rate, how many days will it take the vine to grow to the top of the fence?ANSWERS AVALABLE
A, 32 DAYS C, 96 DAYS
B,64 DAYS D, 63 1/2 DAYS

Answers

current height+amount grown=height of fence
16in+amount grown=4ft
convert 4ft to inches, 12 in per fot, 4*12=48

amount grown==number of days times amount grown per day
amount grown=x times 1/2

16+1/2x=48
minus 16 both sides
1/2x=32
times 2/1 both sides
x= 64

answer is B, 64 days

Is the statement "line plots display individual data" true or false?

Answers

Answer:

The statement "line plots display individual data" is TRUE.

Step-by-step explanation:

A line plot provides an orderly display of all the values in a data set. It displays data as points above a number line to show the frequency of each value denoted by X. This method is a simple and quick way to organize any given data. But this is not useful for very large data set. Generally a data size of 25 to 30 entities is enough for this kind of method.

"Line plots display individual data" is a true statement

Answers

The mixfraction 7(39/80) as a decimal is approximately 7.4875.

We have,

The concept used here is converting a mixednumber to a decimal by adding the decimal equivalent of the fractional part to the whole number.

To convert the mixednumber 7(39/80) to a decimal, we can add the whole number part (7) to the decimal equivalent of the fractional part (39/80).

To convert the fraction 39/80 to a decimal, we divide the numerator (39) by the denominator (80):

39 ÷ 80 ≈ 0.4875

Now, we add the decimal equivalent of the fractional part to the whole number:

7 + 0.4875 = 7.4875

Therefore,

7(39/80) as a decimal is approximately 7.4875.

4,16,8,32,16,
What comes after

Answers

Your answer is 64.
If you look at it the pattern is:
Multiply by 4, then divide by 2
4 times 4= 16
16 divided by 2= 8
8 times 4= 32
32 divided by 2= 16
Now you would multiply by 4
16 times 4= 64

the pattern is:
multiply by 4, divide by 2, multiply by 4...etc
so what comes next is 16*4=64
