Answer:

387.6. So, the closest whole number would be 388 times larger

Step-by-step explanation:

I divided the U.S. pop by the Columbus pop and got the answer: 387.6. So, the closest whole number would be 388 times larger

Answer:

The population of the United States is 387.87 times larger than the population of Columbus, Ohio.

Step-by-step explanation:

8.25 times 100000 = 825,000

3.2 times 100000000 = 320,000,000

320,000,000 divided by 825,000 = 387.87

Answer:  80 miles

Step-by-step explanation:

10mph + 30mph = 40 mph

Distance = Speed × time

D = 40m/h × 2 h

D = 80 m

Y = mx + c

7= (-5)(-2)+ c

7= 10 +c

7-10=c

-3=c

Equation of the line: y = -5x-3

Sub in (a, 2)

2= - 5(a)-3

2+3= -5a

5= - 5a

1= - a

A = -1

Answer:

-7

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let's say :

v = number students in van, b = number of students in bus

From the info provided in the question:

High school A takes 3 vans and 14 buses for 509 students

We can write this as:

3v + 14b = 509

You can re-write this as :

3v = 509 - 14b

We also know High School B takes 12 vans and 10 buses for 472 students:

12v + 10b = 472

Since we already know that 3v = 509 - 14b , substitute this equation into the above formula and you get:

12v + 10b = 472

4(509 - 14b) + 10b = 472

2036 - 56b + 10b = 472

2036 - 46b = 472

2036 - 472 = 46b

1564 = 46b

Divide both sides by 46 to find "b".

b = 1564/ 46 =  34

Therefore the number of students that fit in each bus is 34.

So since we know b = 34, substitute b into the equation at the top:

3v = 509 - 14b

3v = 509 - 14(34)

3v = 509 - 476 = 33

Divide both sides by 3 to find "v".

v = 33/3 = 11.

Therefore the number of students in each van is 11.

Answer:

Of the 600 elephants that he observes in random places in the reserve, he counts [tex]\frac{8}{30}(600)=160[/tex] elephants with broken tusks.

Step-by-step explanation:

Let x denotes number of elephants having broken tusks out of 600 elephants.

Of the 30 elephants that he observes in random places in the reserve, he counts 8 elephants with broken tusks.

So,

Of the 1 elephants that he observes in random places in the reserve, he counts [tex]\frac{8}{30}[/tex] elephants with broken tusks.

Therefore,

Of the 600 elephants that he observes in random places in the reserve, he counts [tex]\frac{8}{30}(600)=160[/tex] elephants with broken tusks.

Answer:

x = [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]\frac{x}{7}[/tex] + x - [tex]\frac{2}{14}[/tex] = [tex]\frac{1}{7}[/tex]

Multiply through by 14 to clear the fractions

2x + 14x - 2 = 2 ( add 2 to both sides )

16x = 4 ( divide both sides by 16 )

x = [tex]\frac{4}{16}[/tex] = [tex]\frac{1}{4}[/tex]

Answer:

[tex]V=2x^2+8x+8[/tex]

Step-by-step explanation:

The volume of a right rectangular prism is given by :

[tex]V=lbh[/tex]

Where,

l is length, bis breadth and h is height

ATQ,

Height of the cage is 2feet

The length and width are both x feet more than the height.

l = b = (x+2)

So,

[tex]V=(x+2)(x+2)2\\\\V=(x+2)^22\\\\V=(x^2+4+4x)2\\\\V=2x^2+8+8x[/tex]

So, the correct option is (D).

Answer:

55 performances

Step-by-step explanation:

The first equation will be the total cost. The total cost has $88,000 already and then $5,900 is added with each performance. So the equation would be 88,000+5,900x because x will represent the number of performances.

y = 88,000 + 5,900x

The next equation will be how much the performances earn. If they earn $7,500 with each performance then the equation will be 7,500x, with x representing the number of performances

y = 7,500x

Now set the equations equal to each other and solve for x

7,500x = 88,000 + 5,900x

1,600x = 88,000

x = 55

They need to have 55 performances for the cost and the revenue to break even.

Answer:

Step-by-step explanation:

vertex form of an equation of the parabola:  

f(x) = a(x - p)² + q

vertex (0, 3)  ⇒  p = 0,  q = 3

so:

   f(x) = a(x - 0)² + 3

    f(x) = ax² + 3

the parabola goes through point (1, -4)  ⇒  x=1,  f(x)=-4

   -4 = a(1)² + 3

   -4 = a + 3

    a = 7

Therefore the equation of the parabola in vertex form:

f(x) = 7x² + 3

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Starting point = 18 inches

Rate or speed = 3 inch per minute

t = number of minutes since climbing began

When will worm be more than 60 inches above the ground.

Height (t) = starting point + (rate * time)

18 + 3t > 60

3t > 60 - 18

3t > 42

t > 42/3

t > 14

Hence, inequality to use is : 60 > 18 + 3t

Answer:

terminating repeating decomal

Step-by-step explanation:

Answer: terminating repeating decimal

Step-by-step explanation: In the subject of Mathematics, we usually classify numbers in several types: whole numbers, rational numbers, natural numbers, and real numbers. We also include decimals in these types. Decimals are used by us to convey a whole number and a fraction together. We do this by separating a whole number from the adjoining fraction by inserting “.” between them. This symbol is called a decimal point. In other words, decimals are just another way of representing fractions.

Answer:

If y> or y>=, (>= means greater than or equal to), then you shade up. If y< or y<=, (<= means less than or equal to), then you shade down. I remember this by up: greater (because when something is bigger, it's higher) and down: less (because if it's smaller, it's lower). I hope that helps.
