Try to slove this question for me please
Answers
The sum of 2 angles on a straight line (supplementary angles) is 180°. Vertical angles (opposites where a line intersects) are equal.
The upper left and lower right angles where p crosses the other lines (q, r, t) are 105°.
180 - 105 = 75°
So the upper right and lower left angles are 75°. The lower left angle where p intersects s is 85°, so it is not parallel to the others.

As you landscape a 4 leaf clover intersection, you will need to buy
enough grass seed to cover all 4 circles. Each of the circles has the same
diameter: 47 meters. Calculate the total area of all grass seed needed to
cover all 4 circles.
Answers
Answer:
A = 6940 m²
Step-by-step explanation:
We are told that there is a clover leaf intersection.
I have attached a picture of it with the 4 circles showing.
We are told the diameter of each circle is the same and equal to 47 m.
Thus, radius = 47/2 = 23.5 m
We want to find the area of grass that will cover the 4 circles. Thus;
Formula for area of a circle is;
A = πr²
For the 4 circles, we have;
A = 4πr² = 4 × π × 23.5²
A = 6939.78 m²
Approximately A = 6940 m²

For the following exercise, use the compound interest formula, A(t) = P(1 +r/n)^t.
where money is measured in dollars.
After a certain number of years, the value of an investment account is represented by the expression 10,400(1 +0.02/2)^20

How many years
Answers
Answer:
A = $10,441.68
A = P + I where
P (principal) = $10,400.00
I (interest) = $41.68
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 0.02/100
r = 0.0002 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 10,400.00(1 + 0.0002/2)(2)(20)
A = 10,400.00(1 + 0.0001)(40)
A = $10,441.68
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $10,400.00 at a rate of 0.02% per year compounded 2 times per year over 20 years is $10,441.68.
The total amount , with compound interest on a principal of $10,400.00 at a rate of 0.02% per year compounded 2 times per year over 20 years is $10,441.68.
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
Compound Interest =[tex]P(1+r/n)^rt[/tex]
Given that
A = $10,441.68
A = P + I
P (principal) = $10,400.00
I (interest) = $41.68
First, we need to convert R as a percent to r as a decimal
r = R/100
r = 0.02/100
r = 0.0002 rate per year,
Then we will solve the equation for A
A = [tex]P(1+r/n)^rt[/tex]
[tex]A = 10,400.00(1 + 0.0002/2)^{(2)(20)}[/tex]
A = 10,400.00(1 + 0.0001)
A = $10,441.68
Hence, The total amount , with compound interest on a principal of $10,400.00 at a rate of 0.02% per year compounded 2 times per year over 20 years is $10,441.68.

Help me I don’t know what this means
Answers
Answer:
46 is the 15th term.
Step-by-step explanation:
In this question they have given us the function 3x + 1 to determine the 15th term in the table. X = the input or the numbers in that column. Now we must substitute x in our function to figure out the output.
Example:
3(1) + 1 = 4
So for the output for 1 the answer would be 4. You must follow this rule for 0 and 2 as well.
For 15 we must substitute 15 for x.
3(15) + 1 = 46
So 46 would be the 15th term.
Answer:
46
Step-by-step explanation:
[tex]3x+1[/tex]
To determine the 15th term using this expression, plug in 15 as x
[tex]= 3(15)+1\\= 45+1\\= 46[/tex]
Therefore, the 15th term is 46.
I hope this helps!
