A=[tex]\pi[/tex]r²
A=[tex]\pi[/tex]100
A=314.159
2 slices = 1/4
1/4x314.159=78.5399 centimters squared.
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.

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.
Answers
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
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
Answers
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.

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.)

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.

Answers
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.
