There are 20 identical solid hemispheres. The curved surface and the flat surface of each hemisphereare are to be painted red and yellow respectively. Find the ratio of the amount of red paint needed to the amount of yellow paint needed.
Answer:
2:1.
Step-by-step explanation:
The area of a red curved surface = 2πr^2.
The area of the yellow flat surface = πr^2.
This is the case for all the hemispheres.
Therefore the required ratio = 2πr^2 : πr^2
= 2:1.

You have 2 five-dollar bills, 4 one-dollar bills, 2 quarters, I nickel, and 2 pennies. a. What is the value of the bills? b. What is the value of the coins? c. How much money do you have?
Answer:
a: [tex]\$ 14[/tex] or [tex]14[/tex] dollars
b: [tex]\$0.57[/tex] or [tex]57[/tex] cents
c: [tex]\$14.57[/tex] or [tex]14[/tex] dollars and [tex]57[/tex] cents
Step-by-step explanation:
a: We have [tex]2[/tex] [tex]\$5[/tex] bills, which have a total value of [tex]2*5= \$10[/tex]. We also have [tex]4[/tex] [tex]\$1[/tex] bills, which have a total value of [tex]4*1= \$4[/tex]. Adding these up gives us [tex]10+4= \bf \$14[/tex] or [tex]\bf 14[/tex] dollars for the total value of the bills.
b: Remember that a quarter is worth [tex]\$0.25[/tex], a nickel is worth [tex]\$0.05[/tex], and a penny is worth [tex]\$0.01[/tex]. Therefore, [tex]2[/tex] quarters are worth [tex]2*0.25=\$0.50[/tex], [tex]1[/tex] nickel is worth [tex]1*0.05=\$0.05[/tex], and [tex]2[/tex] pennies are worth [tex]2*0.01=\$0.02[/tex]. Adding these up gives us [tex]0.50+0.05+0.02=\bf \$0.57[/tex] or [tex]\bf 57[/tex] cents for the total value of the coins.
c: We know that the total value of the bills is [tex]\$ 14[/tex] (or [tex]14[/tex] dollars) from Part A and the total value of the coins is [tex]\$0.57[/tex] (or [tex]57[/tex] cents) from Part B. Therefore, we have [tex]14+0.57=\bf \$ 14.57[/tex] in total or [tex]\bf 14[/tex] dollars and [tex]\bf 57[/tex] cents.

Click this photo.Hope it is helpful...4 |m - n|
-if m = -7 and n= 2
Answer:
9
Step-by-step explanation:
I m - n I = I -7 - 2 I
{ Both are negative integers. So, add and result will have the negative sign}
= I -9 I
= 9
Answer:
-36
Step-by-step explanation:
We have the equation 4 lm - nl , along with the values, m is equal to -7 and n is equal to 2.
To solve, we need to only substitute the values of each variable into the original equation :
4 |-7 - 2|
First solve the equation within the absolute value, any value that comes out of those brackets become positive :
|-7 - 2|
|-9|
4|-9|
4(-9)
Now multiply to get our answer:
4(-9)

Answer:
NO = 10
Step-by-step explanation:
The segment addition theorem tells you ...
MN + NO = MO
Substituting the given expressions for these lengths, we have ...
x + 5x = 3x+6
3x = 6 . . . . . . . . . subtract 3x
x = 2 . . . . . . . . . . divide by 3
We can use this value to find the length NO:
NO = 5x = 5(2) . . . . substitute for x
NO = 10

8 = b - 1 + 8b need answers paper due at 4
Answer:
1 =b
Step-by-step explanation:
8 = b - 1 + 8b
Combine like terms
8 = 9b -1
Add 1 to each side
8+1 = 9b-1+1
9 = 9b
Divide each side by 9
9/9 = 9b/9
1 =b
Answer:
1
Step-by-step explanation:
Group like terms
8b + b = 8+ 1
simplify each sides
9b = 9
divide both sides by 9
9b÷9 = 9÷9
cancel out
answer is equal to 1
b = 1
Which of the following describes the correct process for solving the equation 2x − 6 = 22 and arrives at the correct solution?
Answer:
Subtract 6 from both sides and then divide by 2. The solution is x = 8.
Thank You
Answer:
x=8
Step-by-step explanation:
Um- Please help me, Thanks in advance
(1) Combining fractions is just a matter of writing each individual fraction in terms of a common denominator. The least common multiple of 6, 4, and 8 is
LCM(6, 4, 8) = 24
since 6×4 = 4×6 = 8×3 = 24. So
2/6 = (2×4)/(6×4) = 8/24
1 1/4 = 4/4 + 1/4 = 5/4 = (5×6)/(4×6) = 30/24
13 4/8 = 104/8 + 4/8 = 108/8 = (108×3)/(8×3) = 324/24
Then
2/6 + 1 1/4 + 13 4/8 = 8/24 + 30/24 + 324/24 = 362/24 = 181/12
(2) We have
LCM(12, 9) = 36
since 12×3 = 9×4 = 36. Then
121 2/12 = 1452/12 + 2/12 = 1454/12 = (1454×3)/(12×3) = 4362/36
781 6/9 = 7029/9 + 6/9 = 7035/9 = 2345/3

Find the equation of the line perpendicular to the 13x-3y=9 and passing through (-5,0)
9514 1404 393
Answer:
x +4y = -5
Step-by-step explanation:
The equation of the perpendicular line can be found by swapping the x- and y-coefficients and negating one of them. The new constant can be found by substituting the point values into the equation.
3x +12y = 3(-5) +12(0)
3x +12y = -15
We notice that all of the values include a factor of 3. We can divide that out to put the equation in standard form:
x + 4y = -5
