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.

A. 34
B. 18
C.65
Answer:
A.34
Step-by-step explanation:
f(4)=17
2f(4)=34
if I've understood it :/ but I've didn't understood about g(x)
Answer:
A. 34
Step-by-step explanation:
f (x) = x² + 1. f (4) simply means we should replace X with 4
so it will be
f (4) = 4² + 1
= 16 + 1
= 17
so now 2. f ( 4) means:
2. 17
which gives :
34

Which is further away from zero on the number line -8 or 8
Answer:
Both are equally distant from 0 on a number line.
Step-by-step explanation:
Both are equally distant from 0 on a number line, they are just in opposite directions.
Answer:
Both are same distance
Step-by-step explanation:
-8 is in the opposite direction of the positive 8
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

Answer: x = 30°
Concept:
Here, we need to know the idea of an isosceles triangle and the vertical angle theorem.
An isosceles triangle is a triangle that has any two of its sides equal to each other. Also, the angles opposite these equal sides are equal, which is basically the base angles.
The vertical angle theorem states that two vertical angles formed when two lines intersect each other are always equal to each other.
Solve:
Find the other base angle of the isosceles triangle.
Since there are two equal sides, we know that this is an isosceles triangle.
Since the definition said that the base angles are equal, the other base angle would also be x.
Find the value of x
According to the vertical angle theorem, two vertical angles formed by intersection are equal.
Just as angle x and 30°, are vertical angles formed by intersection, therefore, [tex]\boxed{x=30}[/tex]
Hope this helps!! :)
Please let me know if you have any questions

Answer:
decay
Step-by-step explanation:
The function is in the form
y = a (b)^x
a is the initial value and b is the growth or decay factor
When b < 1 it is decay
When b > 1 it is growth
Since b = .93 it is decay

(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
Point N is on line segment \overline{MO}
MO
. Given MN=2x,MN=2x, NO=x-2,NO=x−2, and MO=2x+9,MO=2x+9, determine the numerical length of \overline{MN}.
MN
.
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

For what value of P, the Quinary number 10P45 represents 134?
If 10p4₅ = 134₁₀, then p is such that
[tex]10p4_5 = 1\times5^3 + 0\times5^2 + p\times5^1+4\times5^0 \\\\ \implies 134 = 125 + 0 + 5p + 4[/tex]
Solve for p :
134 = 129 + 5p
5 = 5p
p = 1

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

Estimating Irrational Numbers
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)

Find h. 10 cm h h = ✓ [?] cm .... 6 cm
Answer:
h²= G²- R²
h² = 10²-6²
h²= 100 - 36
h²= 64
h = √64
.............
Heya!
Answer:
h = √91 cm
Step-by-step explanation:
Apply pythagorean theorem, a² + b² ° c².
Where,
a = ½(6) = 3 cm
b = h
c = 10 cm
Plug in the values
3² + h² = 10²
9 + h² = 100
9 + h² - 9 = 100 - 9
h² = 91
h = √91 cm

Electric saw A cuts planks at a uniform rate of 150 every 30 seconds, and Electric saw B cuts planks at a uniform rate of 130 every 13 second. Of the 2 saws run simultaneously, how many seconds will take for them to produce a total of 225 planks
Saw A = 150 planks/30 seconds = 5 planks per second
Saw B = 130 planks/ 13 seconds = 10 planks per seconds
5 + 10 = 15 planks per second total
225 planks / 15 planks per second = 15 seconds
Answer: 15 seconds
