Jason enjoys watching the squirrels in his neighborhood park. They eat the red oak acorns. After the city removed 4 diseased red

oak trees, the population of squirrels decreased from 105 to 98 in one year. If the population continues to decline at the same rate, how many squirrels will live in the park in 15 years? First, calculate the rate of decay by subtracting the two populations and dividing the difference by the initial population. Then, use the formula A=a0ekt
a. 0 squirrels
b. 95 squirrels
c 81 squirrels
d 34 squirrels ​

4 0

Answer:

0 squirrels

Step-by-step explanation:

If you subtract 98 from 105 then you get 7. That means that 7 squirrels will be lost per year. If you then multiply 7 by 15 (15 is the amount of years) then you get 105 and since there were 105 to start off with, there will be no squirrels left after 15 years.

PQRS is a parallelogram. If mQRS = (9x - 20)° and
ivolga24 [154]

Answer:

x = 8.5

Step-by-step explanation:

In this question, we are to calculate the value of x.

To calculate this, we shall be utilizing one of the important properties of parallelogram.

This property is that opposite angles of a parallelogram are equal.

This means that mQSR = mSPQ = 4x + 90

Now to finally calculate x, we make use of another important parallelogram property which is that angles of parallelogram which faces each other are supplementary.

This means that they add up to be 180

Since mQSR faces mQRS

This means that;

4x + 90 + 9x -20 = 180

13x + 70 = 180

13x = 110

x = 110/13 which is approximately 8.5

explain how you can tell whether a group of ratios represents a proportional relationship. PLEASE HELP
zubka84 [21]
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.

hope this helps :)

The measure of Angle 2 is twelve less than five
hoa [83]

Answer: The measure of Angle 2 = 148°

Step-by-step explanation:

Given: The measure of Angle 2 is twelve less than five  times the measure of Angle 1.

Let the measure of Angle 1 = x

Then, measure of Angle 2 = 5x-12

Since both the angles form linear pair, so their sum = 180°  [linear pair of angles must add up to 180°.]

Then, x+ (5x-12) = 180

⇒ x+ 5x-12= 180

⇒ 6x-12= 180

⇒ 6x= 180+12

⇒ 6x= 192

⇒ x= 32  [divide both sides by 6 ]

So,  measure of Angle 2 = 5(32)-12 = 160-12 = 148°

Hence, the measure of Angle 2 = 148°
