11 is 4% of what number

1 answer:

5 0

<span>First, we must convert the given fraction into a decimal number. So use a calculator or long division to convert the given fraction 11/4  to a decimal number. In this case, 2.75

Now just multiply the equivalent decimal  2.75 by 100 to convert it into a percent. So 100x2.75=275. Take note that we're simply moving the decimal point two spots to the right.

So the given fraction 11/4  is equivalent to 275%
so the answer is 275</span>

At the movies a bag of popcorn cost $3.50 and a bottle of water coast $2.75. If Madeline has $18 and bought two bottles of water

Multiple the cost of the water bottle ($2.75) then whatever you answer is, you subtract that from 18. She should have $12.5 left. The most bags of popcorn she could get is 3. Just add $3.50 until it’s closes to the amounts of money she has left.

How do u do percentage

lbvjy [14]

Answer:

Step-by-step explanation:

Ill try to break this down, simply:

When we talk about percentages we are talking about how much part of something we have and the percent sign is a just a symbol representing that.

Lets say we have 2 out of 10 apples and we need to convert this to a percentage

First think about how many apples we have in total... and that would be 10, and then how many apples we currently have being 2:

So if we put the part that we have over the whole thing we get:

$\frac{2}{10}$

So now lets turn this into a decimal, when its something over 10 its really easy, all we have to do is move the decimal back one place!

So we have 2 and if we move the decimal back one place we get .2 or 0.2

Now we have our decimal, to convert this into a percentage all we have to do is multiply our decimal by 100

So:

0.2 x 100 = 20%

All you do when you multiply by 100 is move the decimal back over 2 places one place for each zero so:

0.2 --> 2. --> 20.

Which gives us again 20%

Daniel and Sydney are getting high-speed Internet access at the same time. Daniel's provider charges $60 for installation and $4

Misha Larkins [42]

Answer:

5 months

Step-by-step explanation:

Daniel's provider charges $60 for installation and $45.95 per month. Sydney's provider has free installation and charges $57.95 per month

Let x = number of months

Daniel = 60 + 45.95x

Sydney = 0 + 57.95x

Equate both equations

60 + 45.95x = 0 + 57.95x

Collect like terms

60 - 0 =57.95x - 45.95x

60 = 12x

Divide both sides by 12

x = 60 / 12

= 5

x = 5 months

Daniel and Sydney would have paid the same amount for high-speed Internet service after 5 months

Two vertical posts stand side by side. One post is 8 feet tall and the other is 17 feet tall. If a 24 foot wire is stretched bet

lianna [129]

Answer:

The distance between the posts is $3\sqrt{55}$ feet.

Step-by-step explanation:

In the attached figure, let DB and AC be the posts and let AD be the wire attached to the top of the posts.

BC is the distance between the posts and we need to find BC.

Note that BC = DE

Also, EC = DB = 8m and AE = AC - EC = 17 - 8 = 9 m.

Now, in the right triangle ADE,

$AD^{2} =AE^{2} +DE^{2}$

$24^{2} =9^{2} +DE^{2}$

$DE^{2} =24^{2} -9^{2}$

= (24+9) (24-9)

= 33(15)

= (3 × 11) × (3 × 5)

$DE=3\sqrt{55}$

Since DE = BC,

$BC=3\sqrt{55}$

Hence, the distance between the posts is $3\sqrt{55}$ feet.
