Find the area of the polygon
Answer:
[tex] 687.5 \: {ft}^{2} [/tex]
Step-by-step explanation:
Area of polygon = Area of square + Area of triangle
[tex] = {25}^{2} + \frac{1}{2} \times 25 \times (30 - 25) \\ \\ = 625 +\frac{1}{2} \times 25 \times5 \\ \\ = 625 + \frac{1}{2} \times 125 \\ \\ = 625 + 62.5 \\ \\ = 687.5 \: {ft}^{2} [/tex]

Average Monthly Temperatures Around the World
Similar to changes in elevation, temperature changes are often expressed as sums and differences of positive and negative rational numbers.
Search the Internet for a website that gives the average monthly high and low temperatures (in degrees Celsius) in Nuuk, Greenland, and in Isla Hoste, Chile. Then answer the following questions based on your research. Answers will vary depending on the website you selected. Document the website you used in the Resources section at the end of this activity.
Part A
What are the average high and low temperatures (in degrees Celsius) for Nuuk in January
Part B
What are the average high and low temperatures (in degrees Celsius) for Isla Hoste in August?
Part C

Find the exact value pf cos 2x if sin x = - 4/5 (Quadrant III)
Answer:
[tex]\displaystyle \cos(2x)=-\frac{7}{25}[/tex]
Step-by-step explanation:
We want to find:
[tex]\displaystyle \cos(2x)\text{ given that }\sin(x)=-\frac{4}{5}[/tex]
And x is in QIII.
Recall that sine is the ratio of the opposite side to the hypotenuse.
Therefore, the adjacent side is (we can ignore the negative for now).
[tex]a=\sqrt{5^2-4^2}=\sqrt{25-16}=\sqrt{9}=3[/tex]
So, the adjacent side is 3, the opposite side is 4, and the hypotenuse is 5.
Using the double angle identity, we can rewrite:
[tex]\cos(2x)=\cos^2(x)-\sin^2(x)[/tex]
Since x is in QIII, cosine is positive, sine is negative, and tangent is negative.
Using the above values, we can conclude that:
[tex]\displaystyle \cos(x)=\frac{3}{5}\text{ and } \sin(x)=-\frac{4}{5}[/tex]
Substitute:
[tex]\displaystyle \cos(2x)=\Big(\frac{3}{5}\Big)^2-\Big(-\frac{4}{5}\Big)^2[/tex]
Evaluate:
[tex]\displaystyle \cos(2x)=\frac{9}{25}-\frac{16}{25}=-\frac{7}{25}[/tex]

Paul built a triangular garden in his backyard, which is enclosed by a rectangular fence. How much of the backyard is not covered by the garden
Answer: 476m²
Step-by-step explanation:
Find the area of the triangle and then subtract it from the area of the rectangle.
Area of triangle = 1/2 * base * height
= 1/2 * 8 * 6
= 24m²
Area of rectangle:
= Length * Width
= 25 * 20
= 500m²
Area not covered by garden:
= 500 - 24
= 476m²

20 − 12
8 + 1
7)
60°
x + 83
40°
A) 7
C) -5
B) -11
D) -3
Answer:
-3
Step-by-step explanation:
Using the Triangle Sum Theorem, we can prove that m<A + m<B + m<C = 180⁰. Looking at the triangle above, it has given us two measurements. We have to find the third measurement. In order to find the third measurement we will use the Triangle Sum Theorem.
m<A + m<B + m<C = 180⁰
x + 83 + 60⁰ + 40⁰ = 180⁰
x + 183⁰ = 180⁰
x + 183⁰ - 183⁰ = 180⁰ - 183⁰
x = -3
Now plug in -3 in the x place.
x + 83
-3 + 83 = 80⁰
Let us make sure that our Triangle Sum Theorem is right.
m<A + m<B + m<C = 180⁰
80⁰ + 60⁰ + 40⁰ = 180⁰
180⁰ = 180⁰
So this makes our answer true. Hope this helps, thank you :) !!

Find the interest on naira 40000.00 for 2 years at 20% per annum compound interest. Please I need the answer ASAP
Given:
Principal value = 40000
Rate of compounded interest = 20%
Time = 2 years
To find:
The interest.
Solution:
Formula for amount is
[tex]A=P\left(1+\dfrac{r}{100}\right)^t[/tex]
Where, P is principal, r is rate of interest and t is time in years.
Putting the given values, we get
[tex]A=40000\left(1+\dfrac{20}{100}\right)^2[/tex]
[tex]A=40000\left(1+\dfrac{1}{5}\right)^2[/tex]
[tex]A=40000\left(\dfrac{6}{5}\right)^2[/tex]
[tex]A=40000\left(\dfrac{36}{25}\right)[/tex]
[tex]A=57600[/tex]
Now, the formula for interest is
[tex]I=A-P[/tex]
[tex]I=57600-40000[/tex]
[tex]I=17600[/tex]
Therefore, the amount of compound interest is 17,600.
The letters P-R-O-B-A-B-I-L-I-T-Y are written on a set of cards. You mix the cards thoroughly. Without looking, you draw one letter then you draw another without replacing the first. Find the probability that you will select a P followed by a Y.
P(P, then Y) =
Answer:
P(P, then Y)=(1/11)(1/10)=1/110
Step-by-step explanation:
The number of letters in probability is 11.
There is 1 P.
The probability of drawing a P on draw 1 is the number of ways of drawing a P, which is 1, divided by the number of ways of drawing any letter, which is 11. Thus:
Probability of drawing a P on the first draw is 1/11.
There are now 10 letters left. There is 1 Y. so
Probability of drawing a Y on the second draw given that you drew a P on the first draw is 1/10.
The probability of drawing a P on the first draw and a Y on the second draw is
(probability of a P on draw 1)(probability of drawing a Y on draw 2, given a P on draw 1)
P(P, then Y)=(1/11)(1/10)=1/110
