Answers

Answer 1

Answer:

the answer is that it will take 3 panters  3.5 hours to pant that room

Step-by-step explanation:

Answer 2

The number of hours taken by the painter to paint the room will be 4.5 hours .

Given,

4 painters can paint a room in 6 hours .

Now according to the method of unitary,

6/4 hours

= 3/2 hours .

Now the number of painters are 3

So if 1 painter paints the room in 3/2 hours then,

3 painters will paint the room in

3*3/2

= 4.5 hours

Thus the number of hours required are 4.5 hours .

Answers

Answer:

21

Step-by-step explanation:

21.

Explanation:

The two-digit number ab stands for 10a + b since the first digit represents 10s and the second represents units. If 10a + b = 7(a + b), then 10a + b = 7a + 7b, and so 3a = 6b, or, more simply, a = 2b. That is, the second digit must be twice the first. The smallest such number is 21.

Brandon has an action figure collection. He keeps 178 of the action figures on his wall, which is 89% of his entire collection. What is the total number of action figures in Brandon's collection?

Answers

Answer:

200 total action figures

Step-by-step explanation:

178 * 100 / 89 = 200

Answer: 200


Steps:

x(.89)=178

Divide both sides by .89 to isolate x

x=200

Check:


If you multiply 200 by .89 to find 89% of 200 you will get 178.

Answer

n-7

Step-by-step explanation:

it represents 7 less than n because you can subtract less than n because 7 is smaller

solve for n: 14.23n - 15 = 41.92

Answers

Hopefully this helps
Answer: n = 4

Steps for Solving Linear Equation

14.23n−15=41.92

Add 15 to both sides.

14.23n=41.92+15

Add 41.92 and 15 to get 56.92.

14.23n=56.92

Divide both sides by 14.23.

n= [tex]\frac{56.92}{14.23}[/tex]

​Expand  [tex]\frac{56.92}{14.23}[/tex]  by multiplying both the numerator and the denominator by 100.

n= [tex]\frac{5692}{1423}[/tex]

Divide 5692 by 1423 to get 4.

n=4

if a puppy weighs 59 oz in 9 weeks how much did I gain if it was 5 oz at birth

Answers

Answer:

54 oz (Which would mean 6 oz/week)

Step-by-step explanation:

To get the answer of 54 oz, subtract 5 oz from 59 oz

D = F - S

D = 59 - 5

D = 54

(For the rate, divided 54 oz gained in 9 weeks)

UR = D/T

UR = 54/9

UR = 6 oz/week

Answer:

54 oz

Step-by-step explanation:

You just do 59-5. The 9 weeks is useless but if its asking for each week, its 6, otherwise its 54.

Answers

Answer:

C. 45x + 1,500 > 3,750

Step-by-step explanation:

You know he has already started on his paper with 1,500 words and he needs to have more words than 3,750 in his final paper which includes the 1,500. Thus, he would have 45x number of words remaining in his paper, according to his speed of 45 words per minute.

Remaining words + 1,500 words must be more than 3,750.

45x + 1,500 > 3,750

The > sign means that something on the left is more than something on the right.
