Answer:

m∠A = 40°

m∠B = 70°

Step-by-step explanation:

The sum of angles in a triangle is 180°.

x + 49 + x + 79 + 70 = 180

2x + 198 = 180

2x = 180 - 198

    = -18

x = -18 ÷ 2

x = -9

m∠A = x + 49

        = (-9) + 49

m∠A = 40°

m∠B = x + 79

        = (-9) + 79

m∠B = 70°

ANSWER

X = -9

EXPLANATION: you subtract 180 - 70 giving you 110

Equation set up: x + 49 + x + 79 = 110

A function f gives the number of stray cats in a town t years since the town started
Bingel [31]

Answer:

  f(0) = 243 . . . cats at the start

Step-by-step explanation:

The exponential function tells you the number of cats after t years is ...

  f(t) = 243(1/3)^t

When t=0, the exponential factor is 1, so the value of the function is the multiplying constant.

  f(0) = 243

This means there were 243 stray cats in town when the animal control program started.

I need 20 characters idk why, but I need a step by step explanation 5y-3(2-y)=10​
lana66690 [7]

____________________________________________________

Solve for y:

5y-3(2-y)=10​

Distribute the -3 to the variables inside the parenthesis.

5y - 6 + 3y = 10

8y - 6 = 10

Add 6 to both sides

8y = 16

Divide both sides by 8

y = 2

How does the ratio of corresponding side lengths of the two quadrilaterals compare with the ratio of the areas of the quadrilate
Wittaler [7]

Answer:

The ratio of the areas would be the ratio of the side lengths squared.

Say the ratio of the side lengths is 1:2, the ratio of the areas would be 1:4. If the ratio of the sides were 2:3, the ratio of the areas would be 4:9.

Hope this helps

Probability ( a flowering plant or fruit plant) is  \frac{13}{30} and Probability (neem plant or peepal plant) is  \frac{29}{60}.

Step-by-step explanation:

Given,

Number of neem plant = 125

Number of peepal plant = 165

Number of creppers plant = 50

Number of fruit plant = 150

Number of flowering plant = 110

To find the probability ( a flowering plant or fruit plant)

and probability ( neem or peepal)

Formula

P( A or B) = P(A) + P(B)

Probability ( a flowering plant or fruit plant) = \frac{110}{600} + \frac{150}{600}

= \frac{260}{600} = \frac{13}{30}

And,

Probability (neem plant or peepal plant) = \frac{125}{600} +\frac{165}{600}

= \frac{290}{600} = \frac{29}{60}
