Answer:

8

Step-by-step explanation:

The perimeter is adding all 4 sides

We know one side is 9

The other three sides are in the ratio

1:2:4

Multiply by x to give the side lengths

x, 2x, 4x

The Perimeter is

9+ x+2x+4x=65

9+7x=65

Subtract 9 from each side

9-9 +7x =65-9

7x = 56

7x/7 = 56/7

x=8

The shortest side is 8

we just need add x next to ratio and sum them all to get perimeter

9 + x + 2x + 4x = 65

7x = 56

x = 8

well since 8(x)<9<16(2x)<(32(4x), then

the shortest side is 8

If x=2y=3z then x:y:z equals what?
Alisiya [41]

Answer: x=6 y=3 z=2

Step-by-step explanation: The question is very vast so im guessing that its just finding 3 whole numbers that can equal the same ammount being multipied by 2 and 3. I chose 6. But theres many others. The answer should be correct because if we replace the letters with the numbers i put in the answer it should look like this: 6=2•3=3•2

When we do simplify this we should get 6=6=6 which is true.

Again you can use different numbers for example 12 as X. Then you need to divide 12 by whats behind the Y. So 12÷2 is 6. So Y is equal to 6. To find Z all you need to do is follow the same steps as Y. Find the number behind Z (3) and divide that into 12. So it would be 12÷3. And if you do the math right it should look like this: X=12, Y=6, Z= 4. And when you imput the numbers to thier corresponding letter it should look like this 12=2(6)=3(4) which simplified looks like 12=12=12 which is true.

A survey of couples in a city found the following probabilities:
liraira [26]

Answer

(a) 0.94

(b)0.06

Step-by-step explanation:

P(husband is employed) = P(H) = 0.85

P(wife is employed) = P(W) = 0.59

P(both are employed) = P(H∩W) = 0.50

(a) At least one of them is employed

= P(H∪W)

= P(H) + P(W) - P(H∩W)

=0.85 + 0.59 - 0.50

=0.94

(b) Neither is employed,

=1 - P(H∪W)

= 1-0.94

=0.06
