Solve (get the variable by itself): m / (-4) = -2.95

1 answer:

7 0

M / -4 = -2.95
As you can see, the variable m is currently in a fraction with a denominator of -4. So to get ride of the fraction and find m and its value, you should multiply both sides by the denominator of the fraction, which is in our case -4.
So m / -4 = -2.95
(m/-4) * -4 = -2.95 * -4
m = 11.8

You can recheck your answer (very important):
m / -4 = 11.8 / -4 = -2.95
The answer has been approved.

Hope this Helps! :)

Sweety’s mother is 12 years more than twice Sweety’s age. After 8 years, she will be 20 years less than three times Sweety’s age

poizon [28]

Answer:

Sweety's age = 16 years and Sweety’s mother’s age = 44 years

Step-by-step explanation:

Let Sweety's age is x.

Sweety’s mother age = 12+2x

After 8 years,

Sweety's age = x+8

Sweety’s mother age = 12+2x+8

Since Mother's age will be 20 years less than three times my age.

2x+20 = 3(x+8)-20

2x+20=3x+24-20

2x+20=3x+4

Taking like terms together,

20-4=3x-2x

x = 16

Sweety's age = 16 years

Sweety’s mother’s age = 12+2x

= 12+2(16)

= 12 + 32

= 44 years

Hence, Sweety’s age and Sweety’s mother’s age is 16 years and 44 years respectively.

A pet store has 10 cats, 9 dogs, and 8 turtles. If Mario randomly selects a pet to take home, determine his Theoretical Probabil

ololo11 [35]

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

STEP (1)

We have to know how many pets does the pet store have.

Look : 10 + 9 + 8 = 27

So the pet store completely have 27 pets.

_________________________________

STEP (2)

Mario randomly selects a pet :

$\frac{10}{27} \\$

Is the Probability of selecting a cat.

##############################

$\frac{9}{27} \\$

Is the Probability of selecting a dog.

_________________________________

STEP (3)

(( or )) in mathematics means plus (( + )) .

So the Probability of selecting a cat or a dog means :

$\frac{10}{27} + \frac{9}{27} = \frac{19}{27} \\$

_________________________________

STEP (4)

There's no STEP 4.

And we're done.

Thanks for watching buddy good luck.

A scrap metal buyer pays $2.79 per square foot of steel.

RUDIKE [14]

Answer:

a. You can earn about $245

b. You will earn about $35 less if the lid is missing

Step-by-step explanation:

a. To solve this we first need to calculate the surface area of the drum, which has a cylinder shape, therefore it's surface area is given by:

surface area = 2*(pi*r² + pi*r*h)

r = d/2 = 4/2 = 2 ft

surface area = 2*(pi*2² + pi*2*5)

surface area = 2*(4*pi + 10*pi) = 2*14*pi = 28*pi ft²

surface area = 87.96 ft²

Since each square foot pays $2.79, then the total value of the drum is:

value = surface area * 2.79 = 87.96*2.79 = $245.42

b. If the lid of the drum is missing, then the surface area is given by:

area drum with no lid = surface area - lid area

area drum with no lid = 87.96 - pi*(2)² = 87.96 - 12.566 = 75.394 ft²

value = area drum with no lid * 2.79

value = 75.394 * 2.79 = 210.35

loss value = 245.42 - 210.35 = $35.07
