If the length of the radius of a circle is doubled, how does that affect the circumference and area?

Answer:

Result = 12

Step-by-step explanation:

Fractions

Fractions are the general expression for rational numbers, defined as

[tex]\displaystyle \frac{a}{b}, \ b\neq 0[/tex]

Where a and b are integer numbers. Some operations with fractions have special rules than those with integers. The product of two or more fractions is

[tex]\displaystyle \frac{x}{y}\cdot \frac{w}{z}\cdot \frac{r}{s}=\frac{xwr}{yzs}[/tex]

We'll use that rule to operate the numbers given in the question:

[tex]\displaystyle 56\cdot \frac{9}{14}\cdot \frac{1}{3}=\frac{504}{42}[/tex]

The fraction can be simplified to an integer by dividing it

[tex]\displaystyle \frac{504}{42}=12[/tex]

Answer:The Answer is 12.

Step-by-step explanation:

When going through a step by step problem you always  wanna go from the left to right.(Unless you have parentheses)

56*9=504

504/14=36

36*1/3=12

There for, you answer is 12.

Hope this helped you. Remember Stay Positive!

The x-Intercepts of the line 2x - 4y = -12 is -6 and the y-intercept is 3.

To identify the x and y intercepts of the line, we set one variable to zero and solve the equation for the other variable.

For the x-intercept, we set y=0 and solve for x in the equation: 2x - 4(0) = -12, hence x = -6.

For the y-intercept, set x=0 and solve for y in the equation: 2(0) - 4y = -12, hence y = 3.

Therefore, the x-intercept is -6 and the y-intercept is 3

Answer:

  see below

Step-by-step explanation:

If suffices to look at the last term. It must simplify to 4/(3w²), so the exponents of z must match in numerator and denominator, and the ratio of constants must reduce to 4/3.

The exponents of z have the right values in choices B and D, but the ratio of constants only matches in choice D. Looking at the rest of choice D, we see that we can factor 6w²z² from both numerator and denominator, then factor 2 from the remaining numerator to make it match the desired form.

  [tex]\dfrac{(12w^2z^4-24w^2z^2)}{18w^4z^2}=\dfrac{6w^2z^2}{6w^2z^2}\cdot\dfrac{2z^2-4}{3w^2}=\dfrac{2(z^2-2)}{3w^2}[/tex]

The answer is in the graph picture

The zeros of the function f(x) = (x - 1)(x - 7) are 1 and 7

The function is given as:

f(x) = (x - 1)(x - 7)

Set the function to 0.

So, we have:

f(x) = (x - 1)(x - 7) = 0

This gives

(x - 1)(x - 7) = 0

Split

(x - 1) = 0 or (x - 7) = 0

Remove brackets

x - 1 = 0 or x - 7 = 0

Solve for x

x = 1 or x = 7

Hence, the zeros of the function are 1 and 7

Make an x and y table, and pick any values to plug in for x in the equation.

I will use the numbers from -2 to 2

Now plug in the values you picked for x into the equation to find its y-value

x = -2

y = 3x - 1   Plug in -2 for x

y = 3(-2) - 1

y = -6 - 1

y = -7

x = -1

y = 3x - 1

y = 3(-1) - 1

y = -3 - 1

y = -4

Answer:

C.

Step-by-step explanation:

2 times 2 times 2 times 5 = 40

The prime factorization of 40 is 2 times 2 times 2 times 5, which can be written as 2^3 * 5. So, option C, "2 times 2 times 2 times 5," is the correct prime factorization of 40.

The prime factorization of the number 40 is 2^3 * 5. To arrive at this factorization, we break down 40 into its prime factors. We start by dividing 40 by the smallest prime number, 2. Since 40 is even, it can be divided by 2 evenly, resulting in 20. We continue this process until we can no longer divide by 2, which leaves us with 20. Now, we try to divide 20 by the next smallest prime, which is also 2. This division gives us 10. Once again, we divide by 2, and we are left with 5. Since 5 is a prime number, we cannot further divide it. Therefore, we have prime factorized 40 as 2 * 2 * 2 * 5, which can be expressed as 2^3 * 5, where the exponent 3 indicates that we have three 2s multiplied together, and the 5 is the prime factor on its own.

Answer:

2000 ml

Step-by-step explanation:

Given: Sarai pours all the liquid from a full small beaker into a  larger beaker.

           The liquid fills the large beaker to 15% of its capacity.

            The small beaker holds 300 ml.

Lets assume capacity of large beaker to hold be "x".

As given, Sarai pours all the liquid from a full small beaker into a larger beaker

∴ [tex]15\% \times x= 300\ ml[/tex]

⇒ [tex]0.15x= 300[/tex]

Dividing both side by 0.15

⇒[tex]x= \frac{300}{0.15}[/tex]

∴ [tex]x= 2000\ ml[/tex]

Hence, the large beaker can hold 2000 ml of liquid.

Answer:

25 minutes is how long Carter played

Step-by-step explanation:

To find out how many minutes Carter plays, multiply 40 minutes by 5/8, which results in 25 minutes of playtime.

To determine the number of minutes Carter plays in a basketball game, which is 40 minutes long, when he plays 5/8 of the game, we use multiplication. We multiply the total game time by the fraction of the game played:

Steps to calculate:

Therefore, Carter plays for 25 minutes of the basketball game.

Answer:

[tex]\frac{8h}{\sqrt{2}} + 16h[/tex]

Step-by-step explanation:

First we need to compute the side length as a function of h

So x be the side length of the right isosceles triangle, in Pythagorean formula we have

[tex]x^2 + x^2 = h^2[/tex]

[tex]2x^2 = h^2[/tex]

[tex]x = \frac{h}{\sqrt{2}}[/tex]

The cost for the legs is

[tex]C_l = 4*2x = \frac{8h}{\sqrt{2}}[/tex]

The cost for the hypotenuse is

[tex]C_h = 16h[/tex]

So the total cost in term of h is

[tex]C = C_l + C_h = \frac{8h}{\sqrt{2}} + 16h[/tex]

The total cost C of construction as a function of h is C =  16 / h +  8√2 / h

The pen is in the shape of an isosceles right angle. This means one of the

angle is 90 degrees and 2 sides of the triangle are equal and the base angles

are equal too.

Using pythagora's theorem

Therefore,

x² + x² = h²

2x² = h²

x² = h² / 2

x = √h²/ √2 = h/√2

cost of the legs = 4 / h/√2 + 4 / h /√2 = 8√2 / h

cost of the hypotenuse = 16 / h

Total cost = 16 / h +  8√2 / h

C =  16 / h +  8√2 / h

Step-by-step explanation:

Let the number be x

Then 4 times a number divided by 3 is 5 more than that number divided by 2 gives the equation:

[tex] \frac{4x}{3} = \frac{x}{2} + 5[/tex]

Multiply through by the LCD, which is 6.

[tex] 6 \times \frac{4x}{3} = 6 \times \frac{x}{2} + 5 \times 6[/tex]

Cancel out to obtain:

[tex] 2 \times 4x =3 \times x + 30[/tex]

[tex]8x = 3x + 30[/tex]

Group similar terms

[tex]8x - 3x = 30[/tex]

Simplify the LHS

[tex]5x = 30[/tex]

Divide both sides by 5 to get:

Answer:

f(x) = 1/2x^2 – 4x + 5  (the third option)

Step-by-step explanation:

I looked it up on a graphing calculator.

The quadratic function that has a minimum located at (4, -3) is:

[tex]f(x) = (1/2)*x^2 - 4x + 5[/tex]

All the options are quadratic functions, so we need to find the one with a leading coefficient positive, which also has a vertex at (4, -3).

The 3 ones with positive leading coefficients are:

[tex]f(x) = (1/2)*x^2 + 4x -11[/tex]

[tex]f(x) = (1/2)*x^2 - 4x + 5[/tex]

[tex]f(x) = 2x^2 - 16x + 35[/tex]

The vertex of the first one is at:

[tex]x = -4/(2*1/2) = -4[/tex]

The x-value of the vertex must be x = 4, so we can discard this.

For the second quadratic function the x-value of the vertex is:

[tex]x = -(-4)/(2*1/2) = 4[/tex]

Then the y-value of the vertex is:

[tex]f(4) = (1/2)*4^2 - 4*4 + 5 = -3[/tex]

Then the vertex is at (4, -3), so this is the correct option.
