George is putting trim around his rectangular deck, including the gate. He will need 46 feet of trim to do the entire deck. If the deck is 15 feet long, how wide is the deck?
A.
6 feet
B.
16 feet
C.
8 feet
D.
23 feet

Answers

Answer:

C: 8 feet

Step-by-step explanation:

You have to find the parameter.

To do that you add all the side lengths together.

15+15=30 now you have to subtract 30 from 46 to find how much room is left.

46-30=16 now divide your answer by 2 to get the 2 remaining sides of the deck.

16/2=8 so the answer is 8!

There are about 7 x 10^6

Step-by-step explanation:

3.5*2029249= 7102347

rounds to 7000000= 7 x 10^6

Answer:

7.102347 times [tex]10^{6}[/tex].

Step-by-step explanation:

Alright. This is an inanely large amount of words, as a drill for scientific notation. The first step is, since the mystery book has 2,029,242 words, to turn this into a single digit multiplied by a power of ten - 2.029242 times [tex]10^{6}[/tex] (apologies for the weird font change in the middle). The science fiction book is 3.5 times larger - multiply 2.029242 on a calculator (unless you really like suffering for some reason; then do it by hand) - it comes out as 7.102347. Thus, the answer is 7.102347 times [tex]10^{6}[/tex].

okay, let's go!
1. for the boys, 3 soccer is 5 basketball (in a group of 8 students).
2. for the girls, 7 soccer is 1 basketball (in a group of 8 students)
3. the question mentions 90 boys like soccer, which means we increased the number of boys surveyed 30x, since 3 times 30 is 90. now, we need to increase the girl numbers by 30 as well, giving us 210 girls who like soccer for every 30 who like basketball.

So start out with -5 then subtract -2 you get -3 then subtract 12-3 and get nine. That’s your answer 9. Hope this helps.

Since the slope is equal to -5 you can already get the beginning of the equation being y=mx+b; M=-5, now to find b you need to plug in your numbers: 12=-5(-2)+b then you get 12=10+b. subtract the 10 to find that b=2 then plug in all the numbers to find the answer y=-5x+2

Patty's Pavers has determined that a paver measuring 5 inches long has a z-score of +1 and a paver measuring 5.25 inches long has a z-score of +2.

Hi! I need Help!
What is the mean length of the pavers produced at Patty's Pavers?

4.25 inches
5.25 inches
4.75 inches
5.75 inches

Thank you!

Answers

Answer:

4.75

Step-by-step explanation: given x=5 inches Z-score =1 let 'X' be the variable in normal distribution z=+1 when x=5 inches.

The mean length of the pavers produced at Patty's Pavers is 4.75 inches. Thus, the correct option is C.

What is Z-score?

A Z-score helps us to understand how far is the data from the mean. It is a measure of how many times the data is above or below the mean. It is given by the formula,

[tex]Z = \dfrac{X- \mu}{\sigma}[/tex]

Where Z is the Z-score,

X is the data point,

μ is the mean and σ is the standard variable.

The Z-score of +1 is,

(x-μ)/σ = 1

(5-μ)/σ = 1

5 - μ = σ

The Z-score of +2 is,

(5.25-μ)/σ = 2

(5.25 - μ)/σ = 2

5.25 - μ = 2σ

Substitute the value of the 'σ', therefore, standard deviation from the above,

5.25 - μ = 2(5 - μ)

5.25 - μ = 10 - 2μ

5.25 - 10 = -2μ + μ

μ = 4.75

Hence, the mean length of the pavers produced at Patty's Pavers is 4.75 inches. Thus, the correct option is C.
