Given that sin 42° ≈0.669, enter the cosine of a complementary angle.
Answer:
0.01167
Step-by-step explanation:
180 - 0.669 = 89.331
complementary angle = 89.331
cos(89.331) = 0.01167

An isosceles triangle has a base 8.8 units long. If the congruent side lengths have measures to the first decimal place, what is
the shortest possible length of the sides?
4.5
8.9
4.3
Od
17.7
b
С
Answer:
4.5
Step-by-step explanation:
For any triangle, the basic principle for these types of problems is that the sum of the 2 shorter sides has to be greater than the longest side, otherwise it is not a triangle, even if it's equal to the longest side.
So, let's look at the first option. 4.5. Since this is an isosceles triangle and the base is 8.8 units, the other side has to be 4.5 as well. 4.5+4.5=9. 9 > 8.8. So, we can immediately eliminate options 8.9 and 17.7. What about 4.3? Well, 4.3+4.3= 8.6, but 8.6 < 8.8, so 8.6 is wrong. So, the answer is 4.5.

A principal of $2900 is invested at 6.25% interest, compounded annually. How much will the investment be worth after 14 years?
Answer:
$6774.4
Step-by-step explanation:
Given data
P=$2900
r= 6.25%
t= 14 years
A=???
The compound interest formula is given as
A=P(1+r)^t
substiute
A= 2900(1+0.0625)^14
A= 2900(1.0625)^14
A= 2900*2.336
A= $6774.4
Hence the final amount is $6774.4

At the beginning of a population study, city had 210,000 people. Each year since, the population has grown by 5.5%. Let t be the number of years since the start of the study. Let y  be the cities population. Write an exponential function showing the relationship between y and t. 
Y=
Answer:
y = 210,000(1.055)^t
Step-by-step explanation:
Initial population: p = 210,000
Annual growth rate: 5.5% = 0.055
Number of years: t
Population in year t: y
y = p(1 + r)^t
y = 210,000(1 + 0.055)^t
y = 210,000(1.055)^t

how many square feet of outdoor carpet will we need for this hole?
MY WORK:
First, you would cut it up into different parts/shapes
(I cut it up into rectangles)
Then, you would find the area of each.
The bottom rectangle: 10 ( 5 times 2 )
The middle rectangle: 12 ( 6 times 2 )
The top rectangle: 8 ( 4 times 2 )
Lastly, you would add!
10 + 12 + 8 = 30
Therefore, the answer is...
30!

I have a spinner that is divided into 4 equal sections colored red, blue, green, and yellow .If I spin the spinner twice ,What is the probability that the spinner will land on yellow both times ?
Answer:
is of 25%
Step-by-step explanation:
The probability that the spinner will land on yellow both times is 1/16.
What is probability?Probability is the chance of occurrence of a certain event out of the total no. of events that can occur in a given context.
Given, A spinner is divided into 4 equal sections colored red, blue, and green.
So, N(S) = 4 and N(R) = 1, N(B) = 1, N(G) = 1 and N(Y) = 1.
Conditional probability is a term used in probability theory to describe the likelihood that one event will follow another given the occurrence of another event.
As the events of getting yellow both times is independent,
The likelihood that the spinner will hit yellow twice is,
P(Y, Y) = P(Y)×P(Y).
P(Y, Y) = (1/4)×(1/4).
P(Y, Y) = 1/16.
