Step-by-step explanation:
Lets have x be the number of 2 point field goals and y be the number of 3 point field goals.
We know that the number of shots was 21, this means that
We know that he scored 47 points, this means that
Answer:
0.5
Step-by-step explanation:
6/13 is the same as saying 6 ÷ 13
6 ÷ 13 = 0.4615384615
The first position after the decimal is the tenths column. Round up, because 6>5.
Answer:
m∠A=42
Step-by-step explanation:
Since they are complementary they must add up to 90°.
(2x+30)+(6x+12)=90
We can just remove parenthesis since you can't really do anything with them.
2x+30+6x+12=90
Combine like terms.
8x<u>+42</u>=90
Do inverse to find the value of x.
<u>8x</u>=48
x=6
Now since we are looking for the m∠A and not x we need to replace the x with the value of x in the ∠A equation.
(<u>2(6)</u>+30)
(<u>12+30</u>)
m∠A=42
Answer: 1
Step-by-step explanation:
The formula for calculating the sum of a Geometric series if the common ratio is greater than 1 is given as :
=
Where is the sum of terms , a is the first term , r is the common ratio and n is the number of terms.
From the question:
= 3280
a = ?
r = 3
n = 8
Substituting this into the formula , we have
3280 =
3280 =
Multiply through by 2 , we have
6560 = a ( 6560)
divide through by 6560, we have
6560/6560 = a(6560)/6560
Therefore : a = 1
The first term of the series is thus 1
