I don’t know the answer

I believe the answer would be yes. Since your dealing with Ratios it would be simple to understand that they are proportional. I'll explain a little better.

This means that if you double this ratio, it will still be equivalent to 1:3

1:3

This is also proportional because this number will always be equivalent to itself.

7:21

Olivia helps paint a square mural in her classroom. Then she helps paint a mural in the hallway whose length is 5 feet longer an
attashe74 [19]
The square mural in Olivia's classroom has dimensions x by x.

Then she paints a mural of dimensions: x+5  (the length) by x-2  (the width).

Thus the second mural (the hallway mural) has the shape of a rectangle with dimensions (x+5) by (x-2), so the area of the second mural is
(x+5)(x-2).

<span>
each side of the classroom mural is 7 feet means that x = 7 ft, 
</span>
thus the area of the hallway mural is :
 (x+5)(x-2)=(7+5)(7-2)=12*5=60    (square feet)


Answer:
<span>C. (x + 5)(x – 2); 60 square feet</span>

If a six-sided die(1-6) and a ten-sided die(1-10) are rolled simultaneously, then what is the probability of rolling both with a
AnnyKZ [126]

Answer:

Pr = 0.20

Step-by-step explanation:

Given

n_1 = 10 ---- 10 sided

n_2 = 6 --- 6 sided

Required

P(x_1,x_2 > 4)

First, list out the sample space

S = \{(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6)(2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)

(3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6) (4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)

(5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6) (6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)

(7, 1) (7, 2) (7, 3) (7, 4) (7, 5) (7, 6) (8, 1) (8, 2) (8, 3) (8, 4) (8, 5) (8, 6)

(9, 1) (9, 2) (9, 3) (9, 4) (9, 5) (9, 6) (10, 1) (10, 2) (10, 3) (10, 4) (10, 5) (10, 6)\}

n(S) = 60 --- total outcomes

The event that the outcome of both is greater than 4 is:

x_1,x_2> 4 = \{(5, 5) (5, 6)(6, 5) (6, 6)(7, 5) (7, 6) (8, 5) (8, 6)(9, 5) (9, 6)  (10, 5) (10, 6)\}

n(x_1,x_2>4) = 12

So, the probability is:

Pr = \frac{n(x_1,x_2>4)}{n(S)}

Pr = \frac{12}{60}

Pr = 0.20
