ANSWER

5.5

EXPLANATION

We can use the cosine rule to find the missing side length.

The cosine rule is given as;

{a}^{2}  =  {b}^{2}  +  {c}^{2}  - 2bc \cos( A)

Let the missing side be "a".

Then,

{a}^{2}  =  {9}^{2}  +  {6}^{2}  - 2 \times 9 \times 6 \cos(37 \degree)

{a}^{2}  =  81+  36- 86.253

{a}^{2}  =  30.74736

a =  \sqrt{30.747}

a \approx5.5

Therefore the missing side length is approximately 5.5 units to the nearest tenth.

Write each fraction as a unit fraction<br> 12/84<br> 13/143<br> 23/138
alexandr1967 [171]
A unit fraction is a fraction whose numerator is 1.

\frac{12}{84}=\frac{12 \div 12}{84 \div 12}=\frac{1}{7} \\ \\&#10;\frac{13}{143}=\frac{13 \div 13}{143 \div 13}=\frac{1}{11} \\ \\&#10;\frac{23}{138}=\frac{23 \div 23}{138 \div 23}=\frac{1}{6}

Help with number two
BabaBlast [244]

Answer:

y = -2x+1

Step-by-step explanation:

We have a point and a slope, so we can use the point slope form of a line

y-y1 = m(x-x1)  where m is the slope and (x1,y1) is the point

y-3 = -2(x--1)

y-3=-2(x+1)

Distribute the 2

y-3 = -2x-2

Add 3 to each side

y-3+3 = -2x-2+3

y = -2x+1

This is in slope intercept form

Suppose that y varies directly with x<br> and y = 10 when x = 20. What is y<br> when x = 15?
tresset_1 [31]

Answer: y = 7.5

Step-by-step explanation:

Suppose that y varies directly with x

That is, y∝x

Convert y∝x to a full equation by introducing a constant k to the right hand side.

Therefore, y = kx

Given that y = 10 and x = 20

Substitute y and x in the equation above. We have;

10 = k(20)

10 = 20k

20k = 10

k = 10/20

k = 0.5

Since k = 0.5, the equation y = kx becomes y = 0.5x

Now, to find y if x = 15, substitute x in equation y = 0.5x

Therefore, y = 0.5(15)

y = 7.5
