1) It's February and you go to the store to buy some food for your pets. You have a Great

Dane and a Savannah cat. The Dane eats 3 times as much as your cat so his food

cost $60 for the big bag and he eats that in one week. The Savannah cats food cost

$15 a bag and it lasts him one week as well. You are there to buy food for the month

and have no more than $300 total to spend. Can you afford a month's worth of food?

3n+5=32

Step-by-step explanation:

this is an example of a 2-step equation.

First, subtract the 5,and cross that out on the left side

and do the same to the other side.

Then you have 3n=32 now, so all you have to do is divide by 3 and you have your answer.

Answer:15.8

Step-by-step explanation:

After 15.81 seconds the hammer reaches the river if the construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

A construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River.

The equation is:

t = √h/4

Plug h = 4000 ft

t = √4000/4

After solving:

t = 15.81 seconds

Thus, after 15.81 seconds the hammer reaches the river if the construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River.

Answer:

3x + y = -16

Step-by-step explanation:

this is because

5x-2x = 3x

6y-5y = 1y which is written as y

-5 -11 = -16

Answer:

First, we start with:

"Ram obtains 40% of the marks in a paper of 200 marks"

In this case, 200 marks represent the 100%

Then how much is the 40%?

we have the relations:

40% = X

100% = 200 marks

Now we can take the quotient of both equations:

(40%/100%) = X/200marks

(40%/100%)*200marks = X = 80 marks

So Ram obtained 80 marks.

Now we have:

"Shyam is ahead of Ram by 25% of Ram's marks"

Now the 100% is the number of marks that Ram has, this is:

100% = 80 marks

And Shyam has 25% more than that, then we have:

125% = X

Same as before, we take the quotient of both equations:

(125%/100%) = X/80 marks

1.25*80 marks = 100 marks.

Shyam has 100 marks.

The last part is (this is not written correctly, it says "one month", it should be "one-ninth")

"while Bhuvan is ahead of Shyam by one-ninth of his own marks."

if his own marks are X, we have the equation

X = 100 + (1/9)*X

X - 1/9*X = 100

X*(8/9) = 100

X = (9/8)*100 = 112.5

So Bhuvan has 112.5 marks

Answer:

Step-by-step explanation:

It is a square based pyramid so any horizontal slice will be a square.

Answer:

3.28 cm

Step-by-step explanation:

The calculation is given below:

we assume the following things

R denotes the radius of the circle

And, A denotes An arc  

Now , the length of the arc is  

L = (A ÷ 360°) × 2 × 3.14 × R

According to the question

R = 6 cm

Angle = 5 minutes and 15 seconds

The clock could complete its revolution in 60 minutes  

Therefore  

60 minutes = 360°

Also

1 min = 60 seconds

So  

1 seconds =  1min ÷ 60seconds  

Now for 15 seconds it is

= 15 seconds × (1 ÷ 60)

= (15 ÷ 60) min

= 0.25 min

 And for 5 minutes and 15 seconds, it is  

= 5 min + 0.25 min

= 5.25 min

Also

60 minutes = 360°

So,  

1 minute = 360° ÷ 60min

Now For  5.25min

= (5.25min) × (360° ÷ 60min)

= 31.5°

Finally the length would be    

L = (31.5° ÷ 360°) × 2 × 3.14 × 6cm

= 3.28 cm

Answer:

Step-by-step explanation:

The required expression represents the number of the small marbles, medium marbles, and large marbles are m = 4s  and l = 3 + 5m.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
Let the number of small marbles be s, medium marbles are m and large marble is l.
According to the question,
He has four times as many small marbles as medium marbles. The number of large marbles is three more than five times the number of medium marbles.
m = 4s
and
l = 3 + 5m

Thus, the required expression represents the number of the small marbles, medium marbles, and large marbles are m = 4s  and l = 3 + 5m.
