Could anybody help me with this easy math I will mark brainliest
Answer:
Step-by-step explanation:
angle 2 is 43 degree because angle 2 and 43 are vertically opposite angle and vertically opposite angles are always equal.
angle 1 is 137 degree because the sum of two angles in a straight line is always 180 degree.so
43+angle 1=180 degree
angle 1=180-43 degree
angle 3 is 137 degree because the relation between between angle 3 and 137 degree is vertically opposite angles and vertically opposite angles are always equal.
vertically opposite angles=e and c
complementary angle=b and c
supplementary angle=e and d

One day, a pet supply store selected every 20th person on a customer list and asked each how many dogs he or she had at home. Ten persons were asked in all.
Number of dogs at home: 2, 1, 3, 2, 2, 1, 4, 0, 1, 4
What is an estimate of the mean number of dogs in a customer’s home?
Enter your answer in the box.
# dogs
Answer: Hey, the answer is 2 dogs
Step-by-step explanation:
"Mean" means Average and these problems are easy to solve I promise there are ten numbers listed add all of them together 2+1+3+2+2+1+4+0+1+4 That will add up to 20 you divide 20 by ten because there are ten numbers. There are good videos about this on Khan academy for median, mode, and mean which I assume is the unit you're on. :)
I will appreciate a quick answer please.
Factorize all of the following
Answer:
(s+16)(s-16)
Step-by-step explanation:
s^2-256
s^2-(16)^2
a^2-b^2= (a+b)(a-b)
(s+16)(s-16)
Answer:
1. 5 ( − 6 ) 2
2. (−16)(+16)
3. ( 7q-3r) ^2
Step-by-step explanation:
5a^2 - 60a + 180 we factor 5 as multiple of a alone (outside of brackets)
Then we keep the common a with its number as 180 doesn't share a
Then we look solely for two numbers that add up to 60 and multiply to 180
We show in the first line what we found and then continue to factor the square of a in format of 5a^(2) and format of -6a-6a to find 5(a2−6a−6a+36) like below until its completed in factored form - 6 -6 would multiply to find +36 and -6-6 subtracts to find -12.
5a^2 - 60a + 180
5( ^ 2 − 1 2 + 3 6)
5 ( ^ 2 − 6 − 6 + 3 6 )
5(a^{2}-6a-6a+36)
5(a2−6a−6a+36)
5 ( ( − 6 ) − 6 ( − 6 ) )
5 ( − 6 ) ( − 6 )
5 ( − 6 ) 2
2.
s^2 - 256
2 + 1 6 − 1 6 − 2 5 6
(+16)−16(+16)
(−16)(+16)
3.
49q^2 + 42qr + 9r^2
(7q )^2 + (7 x 6 + qr) + 3r^2 like by like = 7q and 3r as 3+3 = 6 when squared is our factor outside of brackets and we notice that 6 is not squared in rule.
( 7q-3r) ^2

What is the probability of landing on A then a C?* First Spin Second Spir С C E A B A DC
Answer:
Probability of landing on A: 25% chance
Probability of landing on C: 37.5% chance
Step-by-step explanation:
A. There are 2 A’s out of 8 letters which gives us a fraction of 2/8.
2/8 = 1/4 = 0.25 = 25%
C. There are 3 C’s out of 8 letters which gives us a fraction of 3/8.
3/8 = 0.375 = 37.5%
Hopefully this helped, good luck!

PERIMETER AND AREA
PLZ SHOW WORK
Answer:
perimeter= p1+p2 +p3+p4=add all sides.
area =l×b=
(10m×14m)= 140m
Answer:
Perimeter = 33.4248cm
Area = 29.42478cm²
Step-by-step explanation:
Perimeter = half circle + rectangle length + radius + 90degree section + rectangle length + radius
radius of the circles = (14 - 10)/2 = 2
Perimeter = 2π + 10 + 2 + π + 10 + 2
Perimeter = 3π + 24 = 33.4248cm
Area = half circle + rectangle + quarter circle
Area = π(2)²/2 + 10×2 + π(2)²/4
Area = 29.42478cm²
