Answer:
A
Step-by-step explanation:
We can solve this by guess and check. If we try A, the equation would be 4*7.50+5 = 35. This is true so A is correct.
(If you are unsure you can check other answers too)
Answer:
Step-by-step explanation:
Given you will receive a penny today and the amount is tripled each day
so if we write down each day payment we get a geometric progression.
Day 1=1
Day 2=3
Day 3=9
..
the series is 1,3,9,...
it is a geometric progression with a=1 r=3
we know that the general form of nth term in a GP is t(n)=a
t(n)=1*
now we need to find the amount on 12th day by substituting n=12
we get
t(12)=
He will pay on the 12th day .
Answer:
90degrees
Step-by-step explanation:
To get the measure of angle C, we will use the cosine rule as shown;
AB² = AC²+ BC² - 2(AC)(BC)cos C
85² = 13²+ 84² - 2(13)(84)cos C
7225 = 169 + 7056 - 2184cosC
7225 - 7225 = -2184cosC
0 = -2184cosC
cosC = -0/2184
cosC = 0
C = arccos0
C = 90degrees
Hence the measure of angle C is 90degrees
I think it would be C B and E for number 1 and for the second problem 78 one and 263 thousandths, the next is 782 tenths and 63 thousandths, and 78263 thousandths for the last one. Correct me if I am wrong.
