Answer:
a) 540°
b) 720°
c) 900°
d) 1440°
Step-by-step explanation:
The total measure of internal angles of a convex polygon is given by the formula ...
sum of angles = 180°(n -2) . . . . for an n-sided polygon
So, you count the sides, subtract 2, and multiply that result by 180°.
__
a) 180°(5 -2) = 540°
b) 180°(6 -2) = 720°
c) 180°(7 -2) = 900°
d) 180°(10 -2) = 1440°
Peralta and Amy worked last winter shovelling their neighbour's driveway. Amy earned $8 more than twice the amount earned by Peralta. If their earnings totalled $110, how much did Amy earn? Use an algebraic equation to solve this problem.
Answers
Answer:
$76
Step-by-step explanation:
Peralta and Amy worked last winter shovelling their neighbour's driveway.
Let the amount
Peralta earns = x
Amy earns = y
Amy earned $8 more than twice the amount earned by Peralta.
y = 2x + $8
y = 2x + 8
If their earnings totalled $110,
x + y = 110
x = 110 - y
We substitute 110 - y for x
Hence:
y = 2(110 - y) + 8
y = 220 - 2y + 8
Collect like terms
y + 2y = 220 + 8
3y = 228
y = 228/3
y = 76
Since, the amount Amy earns = y
Therefore, Amy earned $76

A mutiple is found by taking a number and multiplying it by 1, 2, 3, 4, etc. This ensures us that that number will go into each of the numbers we find...or in other words, is a multiple. Choice A gives us 4, 8, and 16. Since 4 * 1 = 4, 4 is a multiple of 4; since 4 * 2 = 8, 4 is a multiple of 8; since 4 * 4 = 16, 4 is a multiple of 16.
Answer:
a) 4,8 and 16

During the month of June, Addison kept track of the number of days she saw birds in her garden. She saw birds on 18 days of the month. What is the experimental probability that she will see birds in her garden on July 1? (There are 30 days in June) HURRYYYYY PLEASE
Answers
Answer:
3/5
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
Experimental probability is based on the result of an experiment that has been carried out multiples times
experimental probability that she will see birds in her garden on July 1 = number of days she saw a bird in June / total number of days in June

Calculate the surface area of the following prism
I will give brainliest too
In case you need formula :
Total area of the lateral faces + 2 x base area = perimeter of the base x height + 2 x base area
Answers
Answer:
63sq. meters
Step-by-step explanation:
The Surface area of the pyramid = 2B + ph
Base area B = 1/2 * 2 * 1.5
B = 1 * 1.5
B = 1.5m²
Perimeter of the base = 2 + 1.5 + 2.5
p = 6m
Height of the priscm = 10m
Substitute into the formula;
TSA = 2(1.5) + 6(10)
TSA = 3.0 + 60
TSA = 63sq. meters
Hence the surface area is 63sq. meters

C = 2 * pi *6
C = 12 pi
Answer:
12π
Step-by-step explanation:
the circumference of the circle can be found using the formula: 2πr.
RW is the radius, and we know that RW=6, so we can plug this into the formula:
C=2πr
C=2π(6)
C=12π

Questions wants to know what her goal was:
When Sasha collected 180 cans, she reached 60% of her goal. This means that 180 is 60% of the goal that she set for herself.
To find this goal, assume that it is denoted as x. In such a case, the goal would be expressed as:
180 = 60% * x
x = 180 / 60%
x = 300 cans
