Answer:

x ≤ 4

Step-by-step explanation:

Given

[tex]\frac{1}{2}[/tex] x + [tex]\frac{8}{4}[/tex] ≤ 4 , that is

[tex]\frac{1}{2}[/tex] x + 2 ≤ 4 ( subtract 2 from both sides )

[tex]\frac{1}{2}[/tex] x ≤ 2 ( multiply both sides by 2 to clear the fraction

The radius of a circular clock is 10.5 inches.Which measurement is the closet to the measurement of the circumference of the clock in inches.

A.33

B.132

C.66

D.346

Answers

Answer:

C: 66 in.

Step-by-step explanation:

The circumference formula is C = 2(pi)(r). Here, r = 10.5 in. Thus, the circumference of the clock to the nearest inch is:

2(3.14)(10.5 in) = 65.94 in, which rounds off to C: 66 in.

HELP ME PLEASE

Answers

Answer:

A. x = -3 ±√10

Step-by-step explanation:

ax² + bx = c

4x² + 24x = 4

The first step is to divide each term by 4 so you have a coefficient of 1 for x².

4(x² + 6x) = 4

Now, you want to divide the b term (6) by 2.

6/2 = 3

Square this quotient.

3² = 9

Because you have a 4 outside of the parentheses, before you add 9, you want to multiply it by 4.

9 • 4 = 36

4(x² + 6x + 9) = 4 + 36

Now, simplify the parentheses. You can use the factoring X, but a shortcut is to use the quotient you found from b/2.

4(x + 3)² = 40

Now, you can divide both sides by 4.

(x + 3)² = 10

Take the square root.

x + 3 = ±√10

Subtract.

x = -3 ±√10

This is your answer.

Hope this helps!

The circumference of a circle is 32 cm which is the closest to the diameter

Answers

Given:

The circumference of a circle is 32 cm.

To find:

The diameter of the circle.

Solution:

We know that, circumference of a circle is

[tex]C=2\pi r[/tex]

It can be written as

[tex]C=\pi d[/tex] [tex][\because d=2r][/tex]

Where, r is the radius of the circle and d is the diameter of the circle.

The circumference of a circle is 32 cm.

[tex]32=\pi d[/tex]

[tex]\dfrac{32}{\pi}=d[/tex]

[tex]\dfrac{32}{3.14}=d[/tex]

[tex]d\approx 10.19[/tex]

Therefore, the diameter of the circle is about 10.19 cm.

Answers

Answer:

Step-by-step explanation:

A charity organization is collecting change to raise money. They have collected three times as many dimes as quarters, 11 more nickels than dimes, and 2 times as many pennies as nickels. Let x represent the number of quarters. Write an expression to represent the number of dimes. Write an expression to represent the number of nickels. Write an expression to represent the number of pennies. If they have collected a total of 4,453 coins, how many of each coin have they collected? Show your work.

Answers

Answer:

x = no. of quarters

3x = no. of dimes

3x + 11 = no. of nickels

2(3x + 11) = no. of pennies

340 quarters

1020 dimes

1031 nickels

2062 pennies

Step-by-step explanation:

x = no. of quarters

3x = no. of dimes

3x + 11 = no. of nickels

2(3x + 11) = no. of pennies

x + 3x + 3x + 11 + 2(3x + 11) = 4453

x + 3x + 3x + 11 + 6x + 22 = 4453

13x + 33 = 4453

13x = 4420

x = 340 quarters

3x = 1020 dimes

3x + 11 = 1031 nickels

2(3x + 11) = 2062 pennies

Check: 340 + 1020 + 1031 + 2062 = 4453

Answer:

The temperature changed by 27F from midnight to noon.

Step-by-step explanation:

We can find the change in degrees by finding the difference of the two temperatures:

10 - (-17) = change in degrees

We can say the difference is equivalent to 10 + 17, since there are two negative signs (the subtraction sign and the negative sign)

So 10 + 17 = 27F difference.
