Answer:
17.98
Step-by-step explanation:
We can use the sum of a finite geometric series formula(in the picture). We can start by plugging in what we have. As of now, we have the first term, 12 and by dividing a term by a previous term, we can tell that the common ratio, r is 1/3. Lastly, we can say that n is equal to 6, because we are looking for the sum of the first 6 terms. After substituting we get:
[tex]\frac{12 - 12*(\frac{1}{3})^6}{1-\frac{1}{3} }[/tex]
We can start by simplifying:
[tex]\frac{12-12(\frac{1}{729}) }{\frac{2}{3} }[/tex]
[tex]\frac{\frac{2916}{243} -\frac{4}{243} }{\frac{2}{3} }[/tex]
[tex]\frac{\frac{2912}{243} }{\frac{2}{3} }[/tex]
[tex]\frac{2912}{243}*\frac{3}{2}[/tex]
[tex]\frac{1456}{81}[/tex]
17.975308642
This can be rounded to 17.98
Answer:
17.98Step-by-step explanation:
Given:
a₁ = 12r = 1/3n = 6Find the sum:
Sₙ = 12(1 - (1/3)⁶)/(1 - 1/3) = 12(1 - 1/729) / (2/3) = 18(728/729) = 17.98 roundedJavi has a bag of marbles that are identical in size. He has 6 red, 4 blue, 7 yellow, and 3
orange marbles. If he draws out two marbles from the bag without replacement, what is the
probability that the first one is red and the second one is orange?
Answer: 50
Step-by-step explanation:
40% of 50 is 20.
We know that 20 of the 50 are plums.
below is just other bits of the problem
There's 30 fruit left.
We know that the ratio for peaches to apricots is 2:3.
If we add 2 and 3 together we get five.
Five divides into 30 six times.
Meaning, we could have 18 apricots, and 12 peaches.
Add all of these numbers together, and you get 18 apricots, 12 peaches, and 20 plums.
18 + 12 + 20 = 50

A model of Spaceship Earth, a major tourist attraction at Epcot Center in Florida, is a sphere whose diameter is approximately 5 inches.
The volume of the model sphere is approximately ___ cubic inches.
Use 3.14 for pi. Round only your final answer to the nearest hundredth.
Answer:
See below.
Step-by-step explanation:
As the diameter is 5 inches, the radius “r” is 5/2 = 2.5 inches.
We calculate the volume of a sphere as follows: [tex]V = 4/3 \pi r^3[/tex]
As we have to use 3.14 for pi, we’ll use that instead of “true” pi.
The formula becomes:
[tex]V = 4/3*3.14*2.5^3 = 65.42[/tex]
The volume of the sphere is 65.42 cubic inches.

A spinner used in a board game is divided into 12 equally sized sectors. Seven of these sectors indicate that the player should move his token forward on the board, three of these sectors indicate that the player should move his token backward, and the remaining sectors award the player bonus points but do not move his token on the board. The total area of the sectors that do not allow the player to move his token is 45.1 inches squared. What is the radius of the spinner
Answer:
9.3 inches
Step-by-step explanation:
The computation of the radius of the spinner be given below:
Let us assume the same be x
So
We know that
Total area of the sector = one-sixth of the total area of the spinner
Given that
45.1 = 1 ÷ 6 × π × r^2
r^2 = 45.1 × 6 ÷ π
r^2 = 86.1
r = 9.279
= 9.3 inches
Jenny has 3 times as many new toys as she has favorite toys. The total number of toys is 60. How many favorite toys might Jenny have?
Answer:Jenny has 15 favorite toys
Step-by-step explanation:
Jenny has 3 times as many new toys as she has favorite toys means that the ratio of new toys to favorite toys can be written as 3:1
Total Ratio=3+1=4
Since the total number of toys is given as 60
Amount of Favorite toys = ratio of favorite toys / Total ratio x Total number of toys
Amount of Favorite toys = 1/4 x 60=15
Therefore Jenny has 15 favorite toys.

Find the value of x with the other angles of 33 and 99
Answer:
48°
Step-by-step explanation:
33+ 99= 132
180 is the sum of all angles so u would subtract 132 from 180 giving you the answer
Answer:
If x is the last angle of a triangle, x=48. is its a just angles its, x=228.
Step-by-step explanation:
If it's a triangle its because triangle sum theorem states that all angles in a triangle add up to 180 degrees. So add the angles you know an subtract it from 180.
If it's just angels then you just need to again, add the angles you know but this time subtract it from 360 as that's he most degrees an angle can go.

I just need help with first 2! Show work please it’s due soon and round answers to the nearest tenth !!!
Answer:
1. To find the volume of a cylinder you'll need to use the formula V = pi(r)^2(h)
V = pi(4)^2(6)
V = 301.59
Rounded* = 301.6
2. A beach ball is a sphere, so we're going to use the formula 4/3pi(r)^3
4/3pi(18)^3
D = 24429.02
Rounded* = 24429.0

Andrew pays $15 for a haircut . He leaves a 20% tip. What is the total amount andrew pays for the haircut, including the tip?
Answer:
$18.00
Step-by-step explanation:
Start by working out 10%, that's easy:
15 ÷ 10 = 1.5
That means a 10% tip would be $1.50, so a 20% tip would be twice that amount:
1.50 x 2 = 3
A 20% tip is $3.00, and added on to the original $15.00, the total is $18.00

A rectangular foto frame has an area of 200 square centimeters.Its lengh is 20 centimeters. a.Find the with of the foto frame b.Find the perimeter of the foto frame
Answer:
Width = 10cmPerimeter = 60 cmStep-by-step explanation:
a. Width
We are given the area and the length so we can use this to find the width using the formula for rate:
Length * Width = Area
20 * w = 200
20w = 200
w = 200/20
w = 10 cm
b. Now that you have both the length and the width, the perimeter is:
= (2 * length) + (2 * width)
= (2 * 20) + (2 * 10)
= 40 + 20
= 60 cm

find the missing sides of the triangle
Answer:
D
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° = [tex]\frac{1}{2}[/tex] , then
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{12}{f}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
f = 24
----------------------------------------------------------------
Using the cosine ratio and the exact value
cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , then
cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{e}{f}[/tex] = [tex]\frac{e}{24}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2e = 24[tex]\sqrt{3}[/tex] ( divide both sides by 2 )
e = 12[tex]\sqrt{3}[/tex]
Answer:
F=24 and e=12[tex]\sqrt{3}[/tex]
