Answer:

240

Step-by-step explanation:

it’s simple math!

Since 60% of the 400 kids want more Library books, all you need to do is:

100% - 60% = 40%

find 40% of 400:

400 x 0.4 = 160

then subtract 160 from 400 to get 60%:

400 - 160 = 240

therefore 240 is your answer! :)

Answer:

\(x=\dfrac{131}{333}\)

Step-by-step explanation:

Assign the decimal to a variable:

Let  \(x=0.\overline{393}\)

Multiply both sides by 1000:

\(\implies x \cdot 1000=0.\overline{393} \cdot 1000\)

\(\implies 1000x=393.\overline{393}\)

Subtract the first equation from the second to eliminate the part after the decimal:

\(\begin{array}{r r c r}& 1000x & = & 393.\overline{393} \\\\- & x & = & 0.\overline{393} \\\\\cline{2-4} \\& 999x & = & 393 \\\end{array}\)

Divide both sides by 999:

\(\implies \dfrac{999x}{999}=\dfrac{393}{999}\)

\(\implies x=\dfrac{393}{999}\)

Reduce the fraction:

\(\implies x=\dfrac{393 \div 3}{999 \div 3}\)

\(\implies x=\dfrac{131}{333}\)

Answer: $12.60

Step-by-step explanation:

after adding to the total with the markers, lunchbox and shirts you get $15.75  then multiply the normal price $15.75 by 20 then divide it by one hundred and you will get $3.15 as your saved amount and you will then do 15.75-3.15= 12.6 make sure to put a 0 after the 6 making it 60.

(2.50+5.25+7.99= $15.75)

(15.75-3.15= 12.60)

Answer:

y = 15

Step-by-step explanation:

We need to solve for k

y = x

21 = 7k  Divide both sides by 7 to solve for k

3 = k

y = xk

y = 5(3)

y = 15

Answer: y = 15

Answer:

27 11/4x

Step-by-step explanation:

First we add the similar parts of the expression.

Whole numbers

6 + 9 + 5 + 7 = 27

Then we add the fractions that dont have x.

We only add the numerators (2 and 3) and dont change the denominators (4)

2/4 + 3/4 = 5/4

Now we add the ones with x.

5/4 + 3/4x + 3/4x = 11/4x

Now we combine those parts together, making

27 11/4x

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Answer:

The answer would be 10.8

Step-by-step explanation:

By finding the missing base side on the original triangle (which is 18), we add 10 to that number to find the base side on the second triangle. We can then use the equation "sin(21.04) = x/30" to find the missing length side (21.04 is the degree measurement).

The height of the wall till the ladder reaches in when it grabs 10 feet farther will be 10.77 feet.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.

The ladder is making a right-angle triangle with a wall as shown below.

By Pythagoras's theorem,

x² = 30² - 24²

x = 18

By Pythagoras's theorem,

y² = 30² - (18 + 10)²

y = 10.77 feet

Hence "The height of the wall till the ladder reaches in when it grabs 10 feet farther will be 10.77 feet".

Answer:

Mountain Peak

Step-by-step explanation:

Mountain peak termed as Pyramidal peak is formed by the movement of multiple glaciers. When glacier starts moving from a central point there by causing erosion of consolidated land mass to form angular and sharp mountain peak.

A glacier while moving/melting carries away the base material attached to it by two ways either plucking or abrasion. Mountain peaks get exposed when the glacier melts down

Answer:

117

Step-by-step explanation:

So basically, how I figured it out is 20-15 is 1/4 of 20. So I had to find the 1/4 of 52 which is 13.  But 15 is 3/4 of 20 so then you multiply 13 times 3 which is 39.

10 is half of 20. So you find half of 52. Which is 26.

52+39+26 is your equation.

Which adds up to 117. So 117 is your answer

I used 20 because in the smaller triangle 20 was the largest side like 52 in the biggest triangle.

Answer:

Company C!

Step-by-step explanation:

In order to see which company has the best buy  we have to see the amount each company sells for one stuffed mascot. In order to do this we have to divide .

Company A:

Company A sells 16 lions for $44.32 this is the same as 1 stuffed lion for $2.77.

Company B:

Company B sells 18 lions for $50.22 this is the same as 1 stuffed lion for  $2.79.

Company C:

Company C sells 12 lions for $32.88 this is the same as 1 stuffed lion for $2.74

Thus as you can see the company with the best buy is company C.

Answer:

The answer of The GCF 10 and 8 is 80

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

Perform the indicated multiplication.  We get  

8x - 6 - 8 = 4 + 2x

Combining the x terms results in:

6x - 14 = 4

Isolate x by adding 14 to both sides:

6x = 18

Find x by dividing both sides by 6:

x = 18/6 = 3

x = 3

The solution or the value of x for the given linear equation 2(4x-3)-8=4+2x is x = 3.

Given that:

2(4x - 3) - 8 = 4 + 2x

Use the distributive property on the left-hand side.

(2 × 4x - 2 × 3) - 8 = 4 + 2x

(8x - 6) - 8 = 4 + 2x

Using the associative property:

8x + (-6 - 8) = 4 + 2x

8x - 14 = 4 + 2x

Subtract both sides by 2x.

8x - 2x - 14 = 4

6x - 14 = 4

Add 14 on both sides.

6x = 18

Divide both sides by 6.

x = 3

Hence, the value of x is 3.
