Answer:

Radius:

radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm.

Diameter:

2 times the radius is the circle's diameter.

Circumference:

The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.the formula for circumference of a circle is 2 x pi x r(radius).

Step-by-step explanation:

u can add 10 plus 8 u can get 18 or if u get other number u wrong

The same amount of students play different instruments so the answer should be:

3 sectors (because there are three different instruments) with 33% in each of them.

Answer: The answer will be C

Because 8 students signed up to play the trumpet, 8 students signed up to play the flute, and 8 students signed up to play the violin. Which means it is equal to each other.  

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

Answer:

\(x=20^o\)

Step-by-step explanation:

from the diagram, we can define the remaining angle in the quadrilateral through the sum of angles in any quadrilateral, which is \(360^o\), so the remaining unknown angle should be:

\(360-(50+2x+x)=310-3x\)

now that we have the unknown angle, we can find x through the point at which the outer angle is. \(x+90\) degrees. (sum of angles at one point is 360 degrees)

\(310-3x +x+90=360\\\\400-2x=360\\2x=400-360\\x=20^o\)

The value of variable x is,

x = 20

We have to given that,

In the diagram below, all angles are given in degrees.

Since, the sum of angles in any quadrilateral is, 360 degree.

Let measure of fourth angle is, y

Hence, We get;

(50 + 2x + y + x ) = 360

50 + 3x + y = 360

3x + y  = 360 - 50

3x + y = 310

y = 310 - 3x

Now, We get;

(310 - 3x) + (x + 90) = 360

Solve for x,

310 - 3x + x + 90 = 360

400 - 2x = 360

400 - 360 = 2x

2x = 40

x = 40/2

x = 20

Therefore, The solution is, 20

Answer:

290,000

Step-by-step explanation:

i got it right in a test i had yesterday

The height of mount Everest in standard form will be 29,000. The correct option is C.

Numbers that are either too large or too little to be conveniently stated in decimal form can be expressed using scientific notation. It could be called scientific form.

It is a numerical indication of the operation of raising a power that is placed above and to the right of a mathematical expression

Given that the height of Mount Everest is represented by 2.9 × 10⁴ feet. The standard form of the number will be written as below:-

2.9 × 10⁴ = 29000

Take the decimal point to the four places right as the power is 4. The number will be 29000 feet.

Therefore, the height of Mount Everest in standard form will be 29,000. The correct option is C.

Step-by-step explanation:

Greetings !

Firstly, plug in give values of the variables to the expression

\(( \frac{8}{4} ) {}^{2} - \frac{16}{8 - 4} \)

apply exponent rule

\(( \frac{a}{b} ) {}^{c} = \frac{a {}^{c} }{b {}^{c} } \)

\( \frac{8 {}^{2} }{4 {}^{2} } = \frac{64}{16} = 4\)

Whereas for the second expression

\( \frac{16}{8 - 4} = \frac{16}{4} = 4 \)

Thus, subtract the numbers

\(4 - 4 = 0\)

Hope it helps!

Answer: 0

Step-by-step explanation:

To solve this problem, plug in. In other words, replace all of the letters with the given numbers. (this is also called substitution, I just described it this way to simplify it).

"a" becomes 8

"b" becomes 4

"c" becomes 16

Answer:

Main part of backpack V = 840 inᶾ

Front pocket of backpack V = 64 inᶾ

Top curve of the backpack V = 395.8406744 inᶾ

Total V = 1299.840674 inᶾ

Step-by-step explanation:

1.

As we know, the formula for the volume of a rectangular prism is width x height x length (V = whl).  We will use this formula to find the volume of the large rectangular prism (bottom part of the backpack) and the volume of the smaller rectangular prism (the pocket).  As for the cylinder, we know the formula for the volume of a cylindrical prism is pi x radius squared x height (V = πr^2h).  We will use this formula to find the volume of the half cylinder (top curve of the backpack).

2.

For the large rectangular prism (main part of the backpack), we are given:

w = 7in

h = 10in

l = 12in

Now let's incorporate our formula for the volume of a rectangular prism into this situation.

V = whl

V = 7 x 10 x 12

V = 840 inᶾ

3.

Now for the smaller rectangular prism (front pocket of backpack), we are given:

w = 2in

h = 4in

l = 8in

Now let's incorporate our formula for the volume of a rectangular prism into this situation.

V = whl

V = 2 x 4 x 8

V = 64 inᶾ

4.

Now to calculate volume for the half cylinder (top curve of the backpack), we must first imagine that this is a full, circular cylinder.  We are given:

r = 6in

h (which will be the same as the width of the backpack in this case scenario) = 7in

Now let's incorporate our formula for the volume of a rectangular prism into this situation.

V* = πr^2h

V* = π x 6^2 x 7

V* = 791.6813487 inᶾ (round this number if you must)

Now that we have the volume of a whole cylinder, we can halve it (divide by two) since we only need half of the cylinder.

V = V*/2

V = 791.6813487/2

V = 395.8406744 inᶾ (round this number if you must)

5.

Finally, we can add our volumes together to acquire the volume of the backpack as a whole!

Large rectangular prism (bottom part of the backpack) + Smaller rectangular prism (the pocket) + Half cylinder (top curve of the backpack) = Total Volume (Whole backpack)

Recall that:

Large rectangular prism (bottom part of the backpack) = 840 inᶾ

Smaller rectangular prism (the pocket) = 64 inᶾ

Half cylinder (top curve of the backpack) = 395.8406744 inᶾ

So:

Total Volume (Whole backpack) = 840 inᶾ + 64 inᶾ + 395.8406744 inᶾ

Total Volume (Whole backpack) = 1299.840674 inᶾ (round this number if you must)

Answer:

The y-intercept is (12,0).

The x-intercept is (0,2).

Step-by-step explanation:

• The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.

• These can be easily found by rearranging the equation to standard slope format and plugging 0 into either variable.

• -24x - 4y = -48.

• -4y = -48 + 24x.

• Divide the entire equation by -4 to isolate y.

• Y = 12 - 6x.

• Plug 0 into x

 ○ Y = 12 - 6(0).

 ○ Y = 12.

• Plug 0 into y

 ○ 0 = 12 - 6x

 ○ 6x = 12

 ○ X = 2

The x intercept is (0,2)

The y intercept is (12,0)

Answer:

3rd choice is your answer

Step-by-step explanation:

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

Answer:

Any negative number and 0 works for the expression.

Step-by-step explanation:

Looking at this type of equation, we know that either EVERY negative number and 0 or EVERY positive number and 0 will work for this equation, since nothing is being added and we're just working with absolutes/negatives.

Let's try a random positive number in the expression

\(|6| = -(6)\\6 \neq -6\)

So this positive number doesn't work, let's just test with another one.

\(|9| = -(9)\\9 \neq -9\)

So we know that positive numbers won't work with this expression.

Let's test 0 quickly, just to make sure.

\(|0| = -0\\0 = 0\)

So 0 works.

Let's try a few negative numbers now.

\(|-5| = -(-5)\\5 = 5\)

So yes, this does work. Let's try one more negative number.

\(|-120| = -(-120)\\120 = 120\)

This works. So, every negative number and 0 work with this equation.

Hope this helped!
