30 out of 40 is equal to what percent

Answer:

12z -32

Step-by-step explanation:

-4(z+3)-4(5-4z)

Distribute

-4z -12 -20 +16z

Combine like terms

12z -32

Step-by-step explanation:

base=5m

height=12

Pythagoras formula A2+b²=c2

so 12²+5²

144+25=169

so

√169=13m

Answer: 3 wires of 13 m =39m

Base side = 5m

Vertical side = 12m

Hypotenuse = length of one wire.

5^2 + 12^2 = Hypotenuse^2

Hypotenuse = 13m

3 wires of 13m length = 39m

Answer:

No, the point (273, 2) does not lie on the circle that is centered at the origin and contains the point (0, -4)

Step-by-step explanation:

The circle centered at the origin that contains the point (0,-4) has equation:

[tex] {x}^{2} + {y}^{2} = 16[/tex]

If the point (273,2) lies on this circle , then it must satisfy this equation:

[tex] {273}^{2} + {2}^{2} = 74533[/tex]

Since

[tex]16 \ne74533[/tex]

The point does not lie on this circle.

Answer:

The radius of the cylinder is (1/2)x units

The area of the cylinder’s base is (1/4)πx2 square units

The height of the cylinder is 4x units

Step-by-step explanation:

The complete question is

A cylinder with a base diameter of x units has a volume of πx3 cubic units.

Which statements about the cylinder are true? Check all that apply.

(1) The radius of the cylinder is (1/2)x units.

(2) The radius of the cylinder is 2x units.

(3) The area of the cylinder’s base is (1/4)πx2 square units.

(4) The area of the cylinder’s base is (1/2)πx2 square units.

(5) The height of the cylinder is 2x units.

(6) The height of the cylinder is 4x units

we know that

The volume of the cylinder is equal to

[tex]V=\pi r^{2}h[/tex]

we have

[tex]r=\frac{x}{2}\ units[/tex] ----> the radius is half the diameter

[tex]V=\pi x^{3}\ units^3[/tex]

substitute the given values  in the formula of volume

[tex]\pi x^3=\pi (\frac{x}{2})^{2}h[/tex]

solve for h

simplify

[tex]x=(\frac{1}{4})h[/tex]

[tex]h=4x\ units[/tex]

Verify each statement

(1) The radius of the cylinder is (1/2)x units

The statement is true

see the explanation

(2) The radius of the cylinder is 2x units.

The statement is false

Because, the radius of the cylinder is x/2 units

(3) The area of the cylinder’s base is (1/4)πx2 square units

The statement is true

Because, the area of the cylinder's base is equal to

[tex]A=\pi r^{2}[/tex]

[tex]r=\frac{x}{2}\ units[/tex]

substitute

[tex]A=\pi (\frac{x}{2})^{2}[/tex]

[tex]A=\frac{\pi x^2}{4}\ units^2[/tex]

(4) The area of the cylinder’s base is (1/2)πx2 square units.

The statement is false

Because, the area of the cylinder's base is equal to

[tex]A=\frac{\pi x^2}{4}\ units^2[/tex]

see the part (3)

(5) The height of the cylinder is 2x units.

The statement is false

Because, the height of the cylinder is 4x units (see the explanation)

(6) The height of the cylinder is 4x units

The statement is true

see the explanation

Answer:

yes A is a SUBSET of U and U is a SUPERSET of A.

Explanation: use curly braces for the elements.

A is a subset of U since U has the elements {1,2,3,4,5,6,7,8,9}, and A has the elements {1,2,3}

U contains the elements listed in set A, so a is a SUBSET of U

Answer:

Below

Step-by-step explanation:

A is a subset of U because 1,2,3 is in set U.

U is a superset of A as U contains 1,2,3 and other elements.

Answer:

2.7 x 5.2 = 14.04

Step-by-step explanation:

You must fill it out accurately so your employer knows how much tax to withhold from your paycheck. The amount withheld  is based on your filing status, number of dependents, anticipated tax credits and deductions. If you do not fill it out correctly, you could possibly end up owing taxes when you file your tax return.

Accurately completing a W-4 form when starting a new job or changing tax status is important to ensure the correct amount of federal income tax is withheld from your paycheck.

When starting a new job or changing tax status, it is important to accurately complete a W-4 form. This form determines the amount of federal income tax that is withheld from your paycheck. By accurately completing the form, you can ensure that the correct amount of tax is being withheld and avoid underpaying or overpaying your taxes.

Completing the W-4 form involves providing information about your filing status, number of allowances, and any additional amount you want to withhold. The number of allowances you claim on the form affects the amount of tax that is withheld. For example, claiming more allowances means less tax will be withheld from your paycheck, resulting in more take-home pay.

Accurately completing the W-4 form is important because it helps you avoid owing a large amount of tax when you file your tax return and potentially facing penalties for underpayment. It also helps you avoid overpaying and potentially receiving a large tax refund. By reviewing and updating your W-4 form when starting a new job or experiencing a change in tax status, you can ensure that the correct amount of tax is being withheld from your paycheck.

Step-by-step explanation:

There are 52.6 kgs of Rice. 26.3 + 26.3 = 52.6

Take 52.6 and minus 35.5 out of it 52.6 – 35.5 = 17.1

there were 17.1 kgs of rice sold

Answer:

minimum value = 10

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

To obtain this form using completing the square

add/subtract ( half the coefficient of the x- term )² to x² - 6x

f(x) = x² + 2(- 3)x + 9 - 9 + 19

     = (x - 3)² + 10 ← in vertex form

with (h, k) = (3, 10 )

To determine maximum or minimum consider the value of a

• If a > 0 then minimum value of k

• If a < 0 then maximum value of k

Here a = 1 > 0, hence minimum value of k = 10

Let S be Sydney's age.

Macy = S + Liyo, Alle = (1/2)S - 1.

Given, S + (S + Liyo) + ((1/2)S - 1) = 31.

Substituting Liyo = S and solving gives Sydney = 10, Macy = 15.

So, Macy is 15 years old.

To solve this problem, let's assign variables to represent each sister's age. Let S be Sydney's age. Given that Macy is Liyo years older than Sydney, Macy's age would be S + Liyo. Since Allie is one year less than half the age of Sydney, Allie's age can be represented as (1/2)S - 1.

The sum of their ages is given as 31, so we can set up the equation: S + (S + Liyo) + ((1/2)S - 1) = 31. Substituting Liyo with S, we can solve for Sydney's age (S). Once we find Sydney's age, we can then find Macy's age by adding Liyo to Sydney's age.

By solving the equation, we find that Sydney is 10 years old. Thus, Macy is 15 years old (10 + Liyo). Therefore, Macy is 15 years old.

Complete Question:

Macy, Sydney, and Alle are sisters. Macy is liyo years older than Sydney and Allie is one war less than half the age of Sydney. If the sum of their ages is 31, how old is Magy?

its 70 miles long

Final answer:

The great bicycle race is 70 miles long.

Explanation:

To find the length of the great bicycle race, we need to multiply the length of the 100-mile astounding race by 7/10. Since 7/10 is a fraction, we can represent it as 7 divided by 10. Multiplying by a fraction is the same as multiplying the numerator by the same factor as the denominator. Therefore, we can multiply 100 by 7 and divide by 10 to find the length of the great bicycle race.

There are a few ways to do this computation. One way is to multiply 100 by 7, which equals 700, and then divide 700 by 10. The result is 70 miles. Therefore, the great bicycle race is 70 miles long.

Maya travels  [tex]4.19 feet/sec[/tex] faster than Kelly !

Difference in distance is : [tex]106.76-56.52 = 50.24 feet[/tex]

Step-by-step explanation:

Here we have , The Carousel in the National Mall has 4 rings of horses. Kelly is riding on the inner ring, which has a radius of 9 feet. Maya is riding on the outer ring, which is 8 feet farther out from the center than the inner ring is. We need to find In one rotation of the carousel, how much farther does Maya travel than Kelly . Let's find out:

Kelly is riding on the inner ring, which has a radius of 9 feet

Total distance traveled by Kelly is circumference of circle with radius 9 feet i.e.

⇒ [tex]Distance = 2\pi r[/tex]

⇒ [tex]Distance = 2(3.14) 9[/tex]

⇒ [tex]Distance = 56.52feet[/tex]

Maya is riding on the outer ring, which is 8 feet farther out from the center than the inner ring .

Total distance traveled by Maya is circumference of circle with radius (8+9=17) feet i.e.

⇒ [tex]Distance = 2\pi r[/tex]

⇒ [tex]Distance = 2(3.14) 17[/tex]

⇒ [tex]Distance = 106.76feet[/tex]

Therefore , Difference in distance is : [tex]106.76-56.52 = 50.24 feet[/tex]

Now , Speed of both is give by

⇒ [tex]Speed_k_e_l_l_y=\frac{56.52}{12} = 4.71 feet/sec[/tex]   And ,

⇒ [tex]Speed_M_a_y_a=\frac{106.76}{12} = 8.90 feet/sec[/tex]

Faster Maya travels = 8.90-4.71 = 4.19

So , Maya travels  [tex]4.19 feet/sec[/tex] faster than Kelly !
