A population of 40 rats living near a restaurant dumpster is growing at a monthly rate of 50%

Mathematics
1 answer:
goldenfox [79]3 years ago
7 0

[(40 ÷ .5) Y] + 40

Parentheses are rat growth

Brackets are rat growth by how many years or just exclude that and the brackets if you don't need to know how many years are there are

The 40 is the amount of rats already there

Growth of rats plus the amount already there.

I'm probably wrong lol

if the first and third of three consecutive odd integers are added, the result is 75 less than five times the second integers. f
Anastaziya [24]

Answer:

<em>The third integer is 27</em>

Step-by-step explanation:

Given

Represent the consecutive odd numbers with T_1, T_2; and\ T_3

Since they are consecutive odds, then

T_2 = 2 + T_1

T_3 = 2 + T_2

<em>From the first statement in the question, we have that</em>

T_1  + T_3 = 5 T_2 - 75

Required

Find the third integer

Recall that

Substitute T_2 = 2 + T_1 in T_3 = 2 + T_2

T_3 = 2 +  2 + T_1

T_3 = 4 + T_1

Substitute T_3 = 4 + T_1 and T_2 = 2 + T_1 in T_1  + T_3 = 5 T_2 - 75

T_1  + 4 + T_1 = 5(2 + T_1) - 75

Open Brackets

T_1  + 4 + T_1 = 10 + 5T_1 - 75

Collect like terms

T_1 + T_1 + 4  = 5T_1 - 75 + 10

2T_1 + 4  = 5T_1 - 65

Collect like terms

2T_1  -  5T_1  = - 65 - 4

-3T_1   = - 69

Divide both sides by -3

\frac{-3T_1}{-3}   = \frac{- 69}{-3}

T_1 = 23

Recall that T_3 = 4 + T_1

T_3 = 4 + 23

T_3 = 27

<em>The third integer is 27</em>

As you were organizing your closet you counted 20 shirts and 12 pairs of pants what was the pants to shirt ratio?
NISA [10]

Answer: 5 : 3

Step-by-step explanation:

The ratio of shirts to pants can be shown by putting the number if shirts and pants in the following manner:

Number of shirts       :        Number of pants

20                               :                   12

Then you have to take this to the lowest term. 4 is a factor of both numbers so when divided by 4 we get:

= 5 : 3

This is the ratio.

Find the value of the variable plz help
Naddika [18.5K]

Answer:

Step-by-step explanation:

Vertically opposite angles are equal.

8y + 36 = 14y -24                Subtract 36 to both sides

8y = 14y - 24 - 36               Combine

8y = 14y - 60                       Subtract 14y from both sides

8y - 14y = - 60

-6y = -60                             Divide by - 6

-6y/-6 = -60/-6

y = 10

===========================

x +48 = 64                        Subtract 48 from both sides

x +48 - 48 = 64-16

x = 16
