= f(2x - 4)

= 4(2x - 4) - 1

Answer:

Y = 40%

R or G = 25%

O = 0%

Step-by-step explanation:

Total M&M's = 7+2+3+8 = 20

PY = 8/20 = .4 or 40%

P(R or G) = (2+3)/20 = 5/20 = .25 = 25%

The length of a rectangular garden is 22 feet longer than its width. If the area of the garden is 408 square feet, what are the dimensions of the garden?
Length=
Width=

Answers

Answer:

Length = 34 ft

Width = 22 ft

I know for SURE!

Pls mar branliest!!

Answer:

Length = 34

Width = 12

Step-by-step explanation:

Let the lenght of the garden be denoted by L, and let the width of the gardne be denoted by W.

The length of a rectangular garden is 22 feet longer than its width:  L=W+22

The area of the garden is 408 square feet: A=LW=408

SubW+22 in for L in the equation LW=408 :

LW=408

(W+22)W=408

[tex]W^{2}[/tex]+22W-408=0

(W-12)(W+34)=0

So we have W=12 and W=-34. However, W can't be equal to -34 as width can't be negative. Therefore, the width of the garden is 12feet.

L=W+22=12+22=34. The length of the garden is 34feet.

If you randomly select a card from a well shuffled standard deck of 52 cards, determine the probability that the card you select is 8.
a) reduce fraction
b) decimal rounded to the nearest thousands
c) percent round to the nearest tenth of a percent

Answers

Answer:

a) 1/13, b) 0.077, c) 7.7%

Step-by-step explanation:

There are 4 cards of 8 in a deck, so the probability is 4/52, which can be reduced to 1/13. 1/13 rounded to the nearest thousandths is 0.077, which is 7.7%.

Need help with this one please explain how you got it

Answers

Answer:

B) 40 feet

Step-by-step explanation:

Essentially, there are two similar right triangles in the given problem.

base_L = Base [larger triangle] = 60 ft

base_S = Base [smaller triangle] = 6 ft

x = leg (larger triangle)

y = leg (smaller triangle) = 4 ft

Using the given proportion to solve for the value of x:

[tex]\frac{x}{base_{_L} } = \frac{y}{base_{_S} }[/tex]

[tex]\frac{x}{60ft} = \frac{4 ft}{6 ft}[/tex]

6x = 240

Divide both sides by 6:

6x/6 = 240/6

x = 40
