what will be number of zeros in the square of the number 100? pls answer fasttttttttttt

Answers

Answer:

4

Step-by-step explanation:

The square of 100 means that 100 is being multiplied by itself. So the square of 100 is 100x100 = 10,000

Whenever you multiply a number by a multiple of 10, you simply add the number of 0s onto the end of the original number, so 100 originally has 2 zeros, so multiplying by 100 will add on another 2 zeros.

So, the number 10,000 which is the square of 100 has 4 zeros.

A hot-air balloon starts 6 feet above the ground and then rises 20 feet each minute.
What equation gives the height h in feet as a function of time t in minutes?
A. h=61
B. h=202
С. h = 204 + 6
D. h=6+ 20

Answers

At starting hot-air balloon starts 6 feet.

So, at t = 0 , h = 6 feet.

Now, distance travelled per minute is 20 feet.

So, extra distance travelled in t minutes is 20t feet.

Now,

Total height = Staring height + increase in height w.r.t time.

h = 6 + 20t

Therefore, the height h in feet as a function of time t in minutes is h = 6 + 20t .

Hence, this is the required solution.

In Argentina, a cow on a ranch is expected to need an average of 4200 m2
of grassland for food.
What size does a ranch need to be to feed 4500 cows?
Give your answer in hectares.​

Answers

The cows of Argentina needs an approximate area of 4200 m² for grazing, and there is a total of 4500 cows.

And we are asked to find the total area of their grazing but in hectares. So, we can write:

[tex]1 \: cow = 4200 \: {m}^{2} [/tex]

Then, for 4500 cows:

[tex]4500 \: cows = 4200 \: {m}^{2} \times 4500[/tex]

[tex]4500 \: cows = 18900000 \: m {}^{2} [/tex]

We know that, 1 hectares = 10000 m² = 10⁴ m²

Then let the area of the field be x in hectares:

[tex]1 \: hectare = 10000 \: {m}^{2} [/tex]

[tex]x \: hectare = 18900000 \: {m}^{2} [/tex]

Then, putting them in proportion, We will get:

[tex]x = \dfrac{18900000}{10000} hectares[/tex]

[tex]x = \boxed{ 1890 \: hectares}[/tex]

So, the total area in hectares = 1890 hectares.

And we are done !!

A circle has a radius of 7 inches. What is the area of the circle? Use 3.14 for p.
(Area of a circle = pr2)

Answers

Answer:

The answer is

153.86 sq. inches

Step-by-step explanation:

Area of a circle is given by

A = πr²

where r is the radius of the circle

From the question

r = 7 inches

So the area of the circle is

A = 3.14(7)²

= 3.14 × 49

We have the final answer as

153.86 sq. inches

Hope this helps you

Here, we are given with a circle whose radius = 7 inches, and we are asked to find the area of the circle. Taking value of π = 3.14

We know,

Area of the circle = πr²

Here,

π = pi (An irrational number used for curves)r = radius of the circle

So, let's find the area,

➝ Area of the circle = πr²

➝ Area of the circle = 3.14 × 7²

➝ Area of the circle = 3.14 × 49

➝ Area of the circle = 153.86 inch²

Hence, Area of the circle:

[tex] \huge{ \boxed{ \bf{153.86 \: {inch}^{2} }}}[/tex]

And we are done !!

The formula a = m – n represents the actual cost, a, of an item with original price m after a coupon for n dollars off is applied. Solve the formula for the amount of the coupon n. A. n = a + m B. n = m – a C. n = a – m D. n = – m – a

Answers

Answer:

n = m - a

Step-by-step explanation:

Given that:

The expression of the formula  a = m - n

where;

a = actual cost of an item

m = original price

n = amount of coupon in dollars

The objective is to solve for the amount of the coupon.

In order to determine the amount of the coupon, we need to make n which is the amount of coupons in dollars the subject of the formula from the given expression.

So if a = m - n

a + n = m

n = m - a

For f(x)=2x+1 and g(x)=x^2-7 find (f-g)(x)

Answers

Answer:

-x² + 2x + 8

Step-by-step explanation:

Essentially we need to subtract g(x) from f(x):

(f - g)(x) = f(x) - g(x) = (2x + 1) - (x² - 7)

Distribute the negative:

(2x + 1) - x² - (-7) = (2x + 1) - x² + 7

Combine like terms:

2x + 1 - x² + 7

-x² + 2x + 8

Thus, the answer is -x² + 2x + 8.
