Answer:
I think the answer is 18 because 20+18=38 and 7x2= 14
Then you would multiply 38 x 2to get 76
14 + 76 = 90

55. Find the area of half of a circle with a radius of 16 mm.
Give your answer correct to three decimal places.
[tex] \huge \green{\underbrace{ \red{\rm \: Answer}}}[/tex]
To find the area of this square, we have to figure out what to do with given radius
r=16r=16 mm.Radius makes half of the square's diagonal, therefore: d=2r=32d=2r=32 mm. Now we have to find the side aa to find the area.
To find aa, use the Pythagorean Theorem.
[tex] d^{2}&=a^{2}+a^{2} \\ 32^{2}&=2a^{2}\\ 1024&=2a^{2}\\ 512\text{ mm}^{2}&=a^{2}a^{2}[/tex]
Set the equation accordingly.
Substitute for d.
You can keep a2 as we will use it in the area.

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
Vivian divides the total amount of money she has evenly between her three children. Each child receives $8.84. Let m be the total money that Vivian has. Write an equation involving m and solve it for the total amount of money that Vivian has (or had).

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

52. x and y are two complementary angles such that y is 16° larger than x.
Find the value of x.
Find the value of y.
Answer:
x= 29 degrees, y= 61 degrees
Step-by-step explanation:
Complementary angles and up to 90 degrees, . Sif half of 90 is 45 and y is 16 more than x, you just need to add 16 to y and subtract 16 from x.
I'm kinda stuck, can anyone help?? Please :) I need an explanation
Can someone please help me on this
for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm
Height = 15 cm
Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,
Area of base = 7× 5/2= 17.5 cm²
Perimeter of base = (7+7+7) = 21 cm
Surface area = 2B + Ph
Surface area of prism = 2×17.5+ 21×10 = 245cm²
Volume = Bh = 17.5×10 = 175 cm³

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. :)

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

Find the missing sides from the right-angled triangled given below
Answer:
8 cm
Step-by-step explanation:
[tex] \large{ \tt{❃ \: STEP - BY - STEP \: EXPLANATION}} : [/tex]
We're provided : In right angled triangle PQR , The length of of PR & length of PQ are 10 cm & 6 cm respectively & we're asked to find out the length of OR.You need to know : The longest side, which is the opposite side of right angle is the hypotenuse ( h ) . When the reference angle is not given , You can assume the remaining sides either perpendicular ( p ) or base ( b ) .Here , Hypotenuse ( h ) = 10 cm , Base ( b ) = ? & Perpendicular ( P ) = 6 cmBefore solving, You will have to know : The square of the hypotenuse of a right - angled triangle is equal to the sum of square of the remaining two sides.[tex] \large{ \tt{❁ \: LET'S\: START}} : [/tex]
[tex] \boxed {\large{ \bf {\: ♕ \: {h}^{2} = {p}^{2} + {b}^{2} }}}[/tex]
- Plug the known values and then simplify !
[tex] \large{ \tt{ ↦ \: {10}^{2} = {6}^{2} + {b}^{2} }}[/tex]
[tex] \large{ \tt{↦100 = 36 + {b}^{2} }}[/tex]
[tex] \large{ \tt{↦36 + {b}^{2} = 100 }}[/tex]
[tex] \large{ \tt{ ↦{b}^{2} = 100 - 36}}[/tex]

[tex] \large{ \tt{↦b = \sqrt{64}}} [/tex]
