Solve the proportion. 8/7 = n/9

Mathematics

RoseWind [281]3 years ago

\frac{8}{7} = \frac{n}{9}

Cross multiply the fractions:

7 \times n = 7n
8 \times 9 = 72

7n = 72

Divide both sides by 7 to get n by itself:

72 \div 7 = 10.28
n = 10.28

The value of n is 10.28.

4) the distance between the x-values is 3 and the distance between the y-values is 4

3² + 4² = d²

9 + 16 = d²

25 = d²

√25 = d

5 = d

Answer: C

6)

d = \sqrt{(x2 - x1)^{2}  + (y2 - y1)^{2} }

d = \sqrt{(-2 - (-3))^{2}  + (2 - (-4))^{2} }

d = \sqrt{(-2 +3)^{2}  + (2 +4)^{2} }

d =  \sqrt{(1)^{2}  + (6)^{2} }

d =  \sqrt{1 + 36}

d = \sqrt{37}

d = 6.1

Answer: A

Which equation could be used to solve for the measure of side Q in the triangle QRS shown below given...
Rama09 [41]

The image is missing, so i have attached it

Answer:

Equation is;

q/sin 105 = 15/sin 30

Step-by-step explanation:

We are given;

Angle Q = 105°

Angle S = 30°

s = 15

From sine rule we know that;

a/sin A = b/sin B = c/sin C.

Thus, applying that to this question, we can find side q.

Thus;. q/Sin Q = s/Sin S

Plugging in the relevant values to obtain ;

q/sin 105 = 15/sin 30
