Answer:
72
Step-by-step explanation:
Cut the square into two equal triangles along the diagonal
You know that half of the diagonal is 6 so multiply that by 2 to get 12 which is the hypotenuse of your triangles
Then use the pythagorean theorem to solve for the sides
a^2 + b^2 = 12^2
a^2 + b^2 = 144
Since the original shape was a square both sides a and b are equal
a^2 = b^2
a^2 + a^2 = 144
2a^2 = 144
a^2 = 144/2
a^2 = 72
a = [tex]\sqrt{72}[/tex]
Since a = b then a = [tex]\sqrt{72}[/tex] =b
Multiply both sides a and b to get the area of the square
[tex]\sqrt{72}[/tex] * [tex]\sqrt{72}[/tex] = 72
The table represents a linear function

Answer:
63 un²
Step-by-step explanation
Formula for Triangle = 1/2(b*h)
------------------------------------------------------------
Lets input our numbers
b(base) = 21
h(height) = 6
------------------------------------------------------------
Lets multiply
1/2(6 x 21) =
1/2(126) = 63

A section of a deck is shaped like a trapezoid. For this section, the length of one base is 31 feet, and the length of the other base is 24 feet. The height is 14 feet. What is the area of this section of the deck?
Area of a trapezoid= (big base+small base)/2 x height
A=(67+54)/2 x 18
A=60.5 x 18
A=1089
This is Adeles solution for the equation x^2+8x- 9 = 0 Step 1 x^2 +8x = 9 Step 2 x^2 +8x + 16 = 9 + 16 Step 3 ( x + 4 ) ^2 = 25 Step 4 x + 4 = 25 or x + 4 = - 25 Step 5 x = 21 or x = - 29. Where did Adele make her mistake? What are the solutions to this equation? Show all of your work. 2. Which would be the best method to use to solve the following equation. Explain your reasoning. A x^2 - 49 = 0 B. x^2 - 3x - 4 = 0 C. x^2 - 2x - 6 = 0
Answer:
Adeles forgot to square root 25 in step 4 therefore the solutions would be 1 and -9
Step-by-step explanation:
Equation : x² + 8x - 9 = 0
Step 1 : x² + 8x = 9
Step 2 : x² + 8x + 16 = 9 + 16
Step 3 : ( x + 4 )² = 25
Step 4 : x + 4 = 25 or x + 4 = - 25
Step 5 : x = 21 or x = - 29.

Given: m∠AKB = 25°
KO = 25
Find: V, Surface Area of of a cone
Please leave answers in term of Pi
Answer:
V = 255.98189 pi
SA = 172.64114π
Step-by-step explanation:
The first thing to do is find the radius.
the measure of angle AKO = 1/2 the measure of angle AKB
m< AKO = 12.5 degrees
Now use trig to find AO (aka the radius)
tan(12.5) = AO/25
AO = 25* tan(12.5)
I'm leaving it like this to get a more accurate number
Now to find the volume
the volume of a cone is pir^2h/3
plugging everything in we get:
pi(25*tan(12.5))^2 * 25/3
which is about 255.98189 pi
Now for surface area
(this is the moment I realize symbols exist)
SA = πr(r+√h²+r²)
plugging everything in we have
π(25tan(12.5))((25tan(12.5)+√625+(25tan(12.5))^2)
I know it looks like a lot but that's mainly because I left the radius as 25tan(12.5)
The Surface Area is about 172.64114π

A=314.159

Paragraph:
Firstly, the question has an error. It says that the personal pan pizza is 80 cm³. It should be cm², since it’s area and not volume. You have to figure out the area of the 20 inch pizza using A=[tex]\pi[/tex]r². Since the diameter is 20, the radius is 10, and the area ends up being 314.159. Two slices is 1/4 of the diameter, or 0.25. Multiply 314.159x0.25, and. You get 78.5399 square centimeters. This is just under the 80 that he is allowing himself, so he has made the correct choice.

Find the AC
47in
14in
26in
7in
Answer: need more of an explanation
Step-by-step explanation:
Answer:
26 in.
Step-by-step explanation:
Since angles A and C are congruent, sides BC and BA are congruent.
7x - 13 = x + 29
6x = 42
x = 7
AC = 3x + 5
AC = 3(7) + 5
AC = 21 + 5
AC = 26

- Max can read about 150 words per minute. Unfortunately for Max, he has waited until
this weekend to do all his reading. The book he has to read is 310 pages long. If a typical
paperback has about 350 words per page, how many hours should he set aside for this
reading?
A. 12 days
B. 12 hours
C. 72.3 days
D. 610 hours
Answer:
B) 12 hours
Explanation
Max can read 150 words per minute. 350 words per page divided by 150 is 2.333, so max can read 1 page in around 2 minutes. There are 310 pages. 2.333 * 310 is around 723. 723 minutes converted to hours is 12 hours. Boom. Done.
Write the following rate as a simplified fraction 76 dogs to 48 cat
Answer:
Do u mean like 19/12
Step-by-step explanation:
Like 76/48 it will be 19/12
Hope I helped u!!
19/12 is the fraction which is represented by rate of 76 dogs to 48 cat.
To write the given rate, "76 dogs to 48 cats," as a simplified fraction, you need to express the number of dogs as the numerator and the number of cats as the denominator.
Therefore, the simplified fraction is:
76/48
To simplify this fraction, you can divide both the numerator and the denominator by their greatest common divisor (GCD), which is 4:
(76 ÷ 4) / (48 ÷ 4)
= 19/12
Hence, 19/12 is the fraction which is represented by rate of 76 dogs to 48 cat.

It can be helpful to remember that a liter is larger than a quart. So 2 quarts will be less than 2 liters. (You may recall reading on the half-gallon container that it holds 1.89 L.)

A bug ran along the number line from -5 to 23. What distance did it cover? If the whole run took the bug 4 minutes, what was its average speed?
Answer:
28 units and 7 units per minute.
Step-by-step explanation:
So if it's a negative number like -5 with a positive number, you have to add.
It would be like ( 5 + 23 ) = 28.
Since it took the bug 4 minutes, divide 28 ÷ 4.
28 ÷ 4 is 7 units per minute.

Sam buys
2 boxes of eggs costing £1.30 each
1 bottle of juice costing £2.60
3 baguettes
He pays with a £10 note and gets a 90p change.
Sam works out the cost of one baguette as £1.70
Is he correct?
You must show your working out.
Answer:
He is wrong
Step-by-step explanation:
£1.30(cost of 1 egg box) x 2=£2.60
2.60(2 egg boxes)+2.60(price of juice)=£5.20(amount spent without baguettes)
10-5.20(amount spent without baguettes)=£4.80
4.80/3=£1.60
£1.60=cost of one baguette
Sam is wrong as the cost of one baguette is £1.60
