Answer: 1 : 4 and 2 : 8

Step-by-step explanation: To find 2 different ratios that are equal to the ratio 3:12, we first rewrite the ratio 3:12 as the fraction 3/12. Notice that we can find 1 of our equal ratios by simply writing this fraction in lowest terms. if we divide both the numerator and denominator of 3/12 by their greatest common factor of 3, we get the equal ratio 1/4.

Now we can use 1/4 to find another equal ratio. If we multiply both the numerator and denominator of 1/4 by 2, we get the equal ratio 2/8.

Finally, remember to write these ratios using the same form as the original problem. 1 : 4 and 2 : 8.

1) Answer: x = 9

<u>Step-by-step explanation:</u>

Same Side Interior Angles are supplementary

15 + 5x + 14x - 6 = 180

19x + 9 = 180

19x = 171

x = 9

***************************************************************

2) Answer: x = 9

<u>Step-by-step explanation:</u>

Corresponding Angles are congruent

13x - 7 = 11x + 11

2x = 18

x = 9

***************************************************************

3) Answer: x = -10

<u>Step-by-step explanation:</u>

Alternating Interior Angles are congruent

90 = x + 100

-10 = x

***************************************************************

3) Answer: x = 7

<u>Step-by-step explanation:</u>

Alternating Exterior Angles are congruent

17x + 1 = 120

17x = 119

Engineers want to design seats in commercial aircraft so that they are wide enough to fit 98% of all males. Men have hip breadths that are normally distributed with a mean of 14.4 inches and a standard deviation of 1 inch. find P98. I really don't understand, help needed please.

-----------------------

Find the z-value with a left tail of 0.98

invNorm(0.98) = 2.0537

-----

Find the corresponding x-value using x = zs+u

 

----

x = 2.0537*1+14.4

---

x = 16.45 inches

ALPHA WHERE ARE YOU?
yKpoI14uk [10]

Answer:

Step 1: 14x − 21 = 1; Step 2: 14x = 22

Explanation:

7(2x−3)=1

Step 1: Simplify both sides of the equation

7(2x−3)=1

(7)(2x)+(7)(−3)=1(Distribute)

14x+−21=1

14x−21=1

Step 2: Add 21 to both sides

14x−21+21=1+21

14x=22

Step 3: Divide both sides by 14

14x / 14 = 22 / 14

x = 22 / 14: x = 11/7
