3,9, 27, 81,...
Answer:
The equation would be if y is the numbers in the sequence (like 3, 9, 27) and x is the is the number in the order (like 3 is 1, 9 is 2, 81 is 4) the the equation would be y = 3^x.

In Game 2, your score started at 2 and doubled every time. Two expressions below represent your score after 12 hits. Select both.
Answer:
B and D
Why are both of the answers to the last question correct?
An exponent is a short way to write repeated multiplication. So 212 means the same as 2 • 2 • . . . • 2 • 2.
Jaxon must sell at least 49 rolls of wrapping paper to support the robotics club fundraiser. He has already sold 24 rolls of wrapping paper. Which inequality best represents the number of rolls of wrapping paper Jaxon still needs to sell
Answer:
x≥25
Step-by-step explanation:
Step one:
given data
Jaxon must sell at least 49 rolls of wrapping paper to support the robotics club fundraiser
We are told that he has already sold 24 rolls of wrapping paper.
Step two:
let x be the number of rolls remaining to be sold,
hence,
x≥49-24
x≥25
Therefore the inequality for the situation is x≥25
which reads that x must be greater than or equal to 25

Answer:
wouldn't they both be 88
I'm not sure if that's correct though
Answer:
x = 88
y = 88
Step-by-step explanation:
66 + 26 + x = 180 (collect like terms)
92 + x = 180 (subtract 92 on both sides)
x = 88
y = x
y = 88
They are vertical so their measures are the same.

Point B is halfway between A and C. The distance from C to D is the same as the distance from D to E, which is the same as the distance from E to F. The area of triangle ACF is 180 cm2. How many square centimeters is the shaded area of triangle BCE?
Answer:
3
Step-by-step explanation:
3
ΔBCE is half the base length and two third the height of ΔACF, therefore,
the area of ΔBCE is less than half the area of ΔACF.
The area of triangle ΔBCE is 60 cm².
Reasons:
In ΔACF, we have;
B = The midpoint of AC
Point E and point D are points on side CF
Distance C to D = Distance D to E = Distance E to F
Area of ΔACT = 180 cm²
Required:
Area of ΔBCE
Solution:
[tex]Area \ of \, \Delta ACF = \mathbf{\dfrac{1}{2} \times AC \times CF} = 180 \ cm^2[/tex]
[tex]In \ \Delta BCE, \, BC = \dfrac{1}{2} \times AC \ and \ CE = \dfrac{2}{3} \times CF[/tex]
Therefore;
[tex]Area \ of \ \Delta BCE = \dfrac{1}{2} \times BC \times CE = \dfrac{1}{2} \times \left(\dfrac{1}{2} \times AC \ \right) \times \dfrac{2}{3} \times CF[/tex]
[tex]\dfrac{1}{2} \times \left(\dfrac{1}{2} \times AC \ \right) \times \dfrac{2}{3} \times CF = \dfrac{1}{2} \times \dfrac{2}{3} \times \left(\dfrac{1}{2} \times AC \ \right)\times CF = \mathbf{\dfrac{1}{3} \times Area \ \Delta ACF}[/tex]
Therefore;
[tex]Area \ of \ \Delta BCE = \dfrac{1}{3} \times Area \ \Delta ACF = \dfrac{1}{3} \times 180 = 60[/tex]
The area of triangle ΔBCE = 60 cm².

work out the area of this semi circle
Answer:
39.27
Step-by-step explanation:
The area of a semi-circle is pi times the radius squared divided by 2. So basically standard area of a circle formula (pi times the radius squared) but then you add in the extra step of dividing it by 2.
The formula looks like this:
π × r² ÷ 2
The radius is half the diameter of the circle. So basically think of it as a line to the middle of the circle. Our diameter is 10, (the diameter is the entire length of the circle. It gives us this already. If you need diameter and only have the radius add the radius together twice or multiply it by 2 to get the diameter. Fun fact..?)
and it tells us to substitute pi for 3.142.
So, plugging our numbers in we get:
3.142 x 5^2 ÷ 2 = 39.275.
Cut out the 3rd decimal place (5) as it tells us to only include the first 2 decimal places, and we finally end up with 39.27.
Hope this helps and have a nice day!

in a bag there are 10 balls numbered 1 to 10 A ball is picked at random find the probability of picking the following
(a) number 7
(b) an odd number
(c) an even number
(d) an prime number
Answer:
a) 1/10
b) 1/2
c) 1/2
d) 2/5
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = Total event/Total sample space
Since there are ten ball in the bag numbered 1 to 10
S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
n(S) = 10
Total sample space = 10
a) If we are to get the probability of picking the number 7.
(E) = {7}
n(E) = 1
Event = 1
Pr(picking 7) = 1/10
b) a) If we are to get the probability of picking an odd number
(E) = {1, 3, 5, 7 , 9}
n(E) = 5
Event = 5
Pr(an odd number) = 5/10 = 1/2
c) a) If we are to get the probability of picking an even number
(E) = {2, 4, 6, 8,10}
n(E) = 5
Event = 5
Pr(an even number) = 5/10 = 1/2
d) a) If we are to get the probability of picking prime
(E) = {2, 3, 5, 7}
n(E) = 4
Event = 4
Pr(prime) = 4/10 = 2/5
