Find the average of all the tests on the first and second test. You find the average by adding up all the test scores and dividing it by the number of test scores you added. Then you can see if she did better than the overal average on each of the tests
Answer:
10.7 cm^2
Step-by-step explanation:
First find the area of the base
A = 1/2 *2*1.7
A =1.7
Then find the area of one of the sides
A = 1/2 (2*3)
A = 3
There are 3 sides and they are identical
Multiply one of the sides by 3
3*3=9
Add the sides and the base together
9+1.7
10.7 cm^2
Circumference is found with the formula
c = pi × d
d is diameter and we will use 3.14 for pi.
The diameter is the measure across the center of the circle. In the first problem, you are given the radius, so we have to multiply by 2 to get the diameter. Then we can use the formula.
12.4 in × 2 = 24.8 in (that's the diameter)
c = pi × D
c = 3.14 × 24.8
c = 77.872 inches
circumference is 77.872 inches.
Try the other problems on your own. They are just like this one. Just make sure they are giving you the diameter and not the radius. Post if you have problems.

SEQUENCE: 6, 18, 54, 162
18/6 = 3
54/18 = 3
162/54 = 3
then, r (common ratio) = 3
_________________________________________
RECURSIVE RULE: r = 3
an = a(n - 1) × r [formula]
ANSWER: an = a(n - 1) × 3
_________________________________________
ITERIATIVE RULE: r = 3, a1 = 6
an = a1 × r^(n - 1) [formula] [ ^(n-1) is an exponent]
ANSWER: an = 6 × 3^(n - 1)
Divide 24 by 6 because that is how many numbers are on the cube which would equal 4
Then multiply 4 and 2 because that's how many possibilities there are of rolling a number less than 4 and is even and the solution is 8
