1)There are 30 students in a class. 18 are girls. Express the number of girls as a percentage of the
class.
2)What is the probability of choosing the color blue from the colors of the rainbow?
Answer:
1) 18/30×100%=60%
Hope this helps!!!
Answer:
See below
Step-by-step explanation:
Hi there!
Question 1
There are 30 students in total and 18 are girls, making 18/30 of the class girls. To express this as a percent, divide, then multiply by 100:
18/30 = 0.6
0.6 × 100 = 60%
Therefore, 60% of the class is girls.
Question 2
There are 7 colours in the rainbow, making blue 1/7 of the colours of the rainbow.
Therefore, the probability of choosing blue from the colours of the rainbow is 1/7.

The total student at Shiloh middle school is 1,400 students. If the ratio of boy to girls is 3:4 for the school how many students are boys and how many students are girls
There are 600 boys and 800 girls.
SOLUTION:We are given the following facts:
The total number of students is 1,400.The ratio of boys to girls is 3:4.We express this as a partitive proportion.
» Solve for x.
[tex] \sf 3x + 4x = 1400 [/tex][tex] \sf 7x = 1400 [/tex][tex] \sf x = \frac{1400}{7} [/tex][tex] \sf x = 200 [/tex]Now we to solve for the number of boys and the number of girls.
» Number of boys:
= [tex] \sf 3x [/tex] = [tex] \sf (3)(200) [/tex] = [tex] {\boxed{\sf 600}} [/tex]» Number of girls:
= [tex] \sf 4x [/tex] = [tex] \sf (4)(200) [/tex] = [tex] {\boxed{\sf 800}} [/tex]Thus, there are 600 boys and 800 girls. The sum of these is the total number of students in Shiloh Middle School.

Adam has some marbles.
Bradley has twice as many marbles are Adam.
Chris has 5 more marbles than Bradley.
In total they have 55 marbles.
How many marbles does Chris have?
Answer:
Chris has 25 Marbles
Step-by-step explanation:
If Adam starts with 10, Bradley will have twice as many, meaning Bradley's amount is 20. Making the new total, 30 Marbles. Chris has 5 More Marbles than Bradley, making Chris have 25 Marbles. If you add the total's up, you get 55 Marbles in total.

#3) Find the measure of arc N).
Answer:
Arc NJ is 65°
Step-by-step explanation:
An entire circle measures 360°
Therefore, add all the given dimensions and subtract the sum to 360
> 150+50+50+45 = 295
> 360-295 = 65
Therefore, the measurement of arc NJ is 65
If 11 - 3x = x, then 20x=
Answer:
20x = 55
Step-by-step explanation:
First you have to add 3x to both sides of 11-3x=x
[tex]11-3x=x\\+3x=+3x\\11=4x[/tex]
Now that you have 11 = 4x you divide 4 on both sides [tex]\frac{11}{4} =\frac{4x}{4}[/tex]
11/4 = x
But you can't divide 11 by 4 unless you are looking for the decimal form of 11/4 which is 2.75
so now we take 11/4 or 2.75 depending on if you need your answer in fraction or as a decimal and replace that with x however both will equal the number 55
[tex]20(\frac{11}{4})=55\\20(2.75)=55[/tex]
Write the standard form of the equation of the circle with a radius of 7 and center (2,-4).

Step-by-step explanation:
angle 5 = supplementary to 89 = 180-89 = 91°
the sum of all angles in a triangle is always 180°.
so,
angle 3 = 180 - 51 - 91 = 38°
angle 2 = complementary to 38 = 90-38 = 52°
therefore,
angle 1 = 180 - 38 - 52 = 90°

Of the houses in Kimberly's neighborhood, 5/12 are pink and another 1/3 are red. What fraction of the houses are either pink or red?
Answer:9/12
Step-by-step explanation:
You need to make the denominators the same. Multiply the 1/3 by 4 and now you are ready. You add 4/12 and 5/12 together. 9/12 houses on her block are pink/red. You can also simply it down to 3/4.

Answer:
Step-by-step explanation:
Sum of all the angles of the polygon = (n -2) *180
= (6 - 2) * 180 = 4 *180 = 720
45 + 135 + 45 + 135 + x + 3x = 720
360 + 4x = 720
4x = 720 - 360
4x = 360
x = 360/4
x = 90
3x = 3*90 = 270

to visit a client's home, plus an additional $20 per hour.
Write an equation that shows how the cost of a visit, y, depends on its duration in hours, X.
Answer:
y=20x+35
Step-by-step explanation:
if a plumber who is just starting out offers low rates to attract new customers. He charges $35 to visit a client's home, plus an additional $20 per hour. Then y=20x+35 is equation that shows how the cost of a visit, y, depends on its duration in hours, X.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that
a plumber who is just starting out offers low rates to attract new customers
Plumber charges $35 to visit a client's home, plus an additional $20 per hour.
Let the charges per hour be denoted by x.
and it is given that y is cost of a visit.
We are required to write equation for cost of a visit y.
y equal to twenty x plus thirty five.
y=20x+35
Hence if a plumber who is just starting out offers low rates to attract new customers. He charges $35 to visit a client's home, plus an additional $20 per hour. Then y=20x+35 is equation that shows how the cost of a visit, y, depends on its duration in hours, X.

Steve had 1400 pesos. Heloaned 500 pesos to a friend, spent 310 pesos, and received his800 pesos paycheck from work. How much money does he have now?
Answer:
1390
Step-by-step explanation:
1400- 500= 900 (loaned → deduction→ meaning subtraction)
900- 310 = 590 (spent→ deduction→ meaning subtraction)
590 + 800 = 1390 (received→ gained→ addition)
A sphere has a radius of 4 inches. Determine the effects on the surface area and volume of a sphere when the radius is changed.
Answer:
Step-by-step explanation:
The surface area of a sphere is given by
A=4πr^2
The volume is
V = (4/3)πr^3
At r = 4":
A = 64π in^2
V = 85.3π in^3
At r = 5" (a 25% increase in r)
A = 100π in^2 (a 156.25% increase)
V = 167π in^3 ( a 195.8% increase)
We can show the ratio of these two measures by dividing the Volume by the Area:
V/A = ((4/3)πr^3/(4πr^2))
V/A = (1/3)r
For the 2 examples (4" and 5"), V/A is:
4": (85.3π in^3)/(64π in^2) = 1.33 [(1/3)r = 4/3 = 1.33]
5": (167π in^3)/(100π in^2) = 1.67 [(1/3)r = 5/3 = 1.67]
V/A = (1/3)r
Since Volume is a function of r^3 and Area is related to r^2, Volume will always increase faster, by a ratio of 1/3 r.

37,162 Divided by 10 to the third power equals what
Answer:
37.162
Step-by-step explanation:
We know that 10 to the third power is 10³ = 1000. When a number is divided by 1000, the decimal point is moved 3 digits to the left. Therefore, we can get 37,162/1000 = 37.162
