Answer:
Emily's mother will donate $20
Step-by-step explanation:
0.5x20=10
Answer:
Emily will donate $24
Step-by-step explanation:
0.25 = 1 quarter of a mile there are 4 quarters in 1 mile, so there are 15x4 = 60 quarters in 15 miles, therefore, Emily's mom will have to donate $0.40 x 60 = $24
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.
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

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

Complete the square to solve 4x2 + 24x = 4.
O A. x= -3 + 10
O B. x = 4 + 40
C. X= 3 + 10
O D. X= -4 + 20
HELP ME PLEASE
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!
Look at the ingredients needed to make Josie's special pancakes. How much pancake mix and milk will you need if you want to double the recipe? to triple the recipe? solve this problem anyway you choose math answer
Answer:
Double - 7 5/6
Explantion: 2 1/4 times 2 equal 4 1/2 for the pancake mix
1 2/3 times 2 equal 3 1/3 for the milk
So.....4 1/2 plus 3 1/3 equals 7 5/6
Triple- 11 3/4
Explantion: 2 1/4 times 3 equals 6 3/4 for the pancake mix
1 2/3 times 3 for the milk equals 5
So.... 5 plus 6 3/4 equal 11 3/4
Hope it help :)
Is Valparaiso warmer, colder, or the same temperature as Sydney
Answer: Sydney is warmer because Sydney is closer to the equator. Valparaiso is warmer because it is further away from the equator.
Can someone give me the answer an an explanation PLZZ
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.

Solve the inequality for X
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
x ≤ 4
