Answer:
The radius is 4.5, while the area is equaled to 63.585
Step-by-step explanation:
Formula of circumference: radius times 2 times pie (3.14)
Formula of Area of Circle: radius squared times pie (3.14)
Divide 28.26 by 2 and by pie (3.14) to get the radius. You should get 4.5.
Square 4.5 (the radius), which should equal to 20.25. Then, multiply it by pie (3.14), which is equaled to 63.585. This is the area of the circle.
What is the length of segment AB? (1 point)
Coordinate grid shown from negative 8 to positive 8 on both x axis and y axis at intervals of 1. A straight line labeled AB is drawn. A is the ordered pair 0, 6 and B is the ordered pair 7, 0.
Group of answer choices
Square root of 13
Square root of 85
14
13
Answer:
Square root of 85
Step-by-step explanation:
We can envision the segment AB as the hypotenuse of a right triangle with a height of 6 units and a length of 7 units. We can use the Pythagorean Theorem to solve for the length of segment AB which is similar to distance formula.
6^2 + 7^2 = c^2
36 + 49 = c^2
c^2 = 85
c = Square root of 85.

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. The Smiths are sending out a batch of holiday cards. Emily signed of the cards. Then Josh signed of the remaining cards. Tatiana signed 20% of what Josh had left. If there were 75 cards in all, how many cards are left to be signed? There are cards yet to be signed.
Answer:
You will get 75 cards
Step-by-step explanation:
The answer is 32
Emily signed 2/5 so 75 divided by 5 is 15
15x2 is 30
75-30=45
45 divided by 1/9 is 5
30+5=35
so then 45-5=40
20% of 40 is 8
30+5+8 = 43
75-43=32

Pizza Hut charges $10 per large pizza plus a $4 delivery fee. If you spent a total of $34, how many pizzas did you order
Answer:
3 pizzas
Step-by-step explanation:
34-4=30
30/10=3
Answer:
3 pizzas
Step-by-step explanation:
34-4=30 since we already know the delivery fee
30/10=3 since we have 30 dollars left without the delivery fee we are just left to divide 30 by 10 to get the total number of pizzas

The ratio of dogs to cats at the SPCA is 3:2. If there are 48 cats, how many dogs are there?
Answer:
72 dogs
Step-by-step explanation:
3 dogs/2 cats = x dogs/48 cats
Cross Multiply
3/2 x x/48
2x=144
x=72
Answer:
72 dogs
Step-by-step explanation:
First turn 3:2 into a fraction:
3/2
Then you can make the equation a proportion question, which is much eaiser to handle.
3/2=x/48 (I recommend writing this out so it will be easier to see)
Then you cross multiply, or multiply by the numerator of the first fraction by the denominator of the second, and the denominator of the first fraction by the numerator of the second.
Multiply 2 by x, which becomes 2x.
Multiply 3 by 48, which is 144
This becomes... 2x=144
You then solve with equation by dividing 144/2 and getting 72.
Meaning x=72 dogs

65/100 pounds
Step-by-step explanation:
P.S Can I have brainliest?
Answer:
13/20
Step-by-step explanation:
Write 0.65 as [tex]\frac{0.65}{1}[/tex]
Multiply both numerator and denominator by 10 for every number after the decimal point
0.65 × 100/1 × 100 = [tex]\frac{65}{100}[/tex]
[tex]\frac{65}{100}[/tex] reduced is 13/20

Given trapezoid ABCD whose bases are segment AB and segment CD, what is mZB?
Answer:
x = 19
<B = 125°
Step-by-step explanation:
The sum f angle <D and angle <A is equal to 180° because these angles are supplementary
75° + 5x + 10 = 180° add like terms
85 + 5x = 180 subtract 85 from both sides
5x = 95 divide both sides by 5
x = 19
Same rule goes for angle <C and angle <B
<B + 55° = 180 subtract 55 from both sides
<B = 125°
Jorie leaves work 30 minutes late. She decides to make up time by taking the toll road instead of side streets. She can travel four times faster by taking the toll road. Create an equation to represent her total travel time, including wait time, where x is the number of minutes the drive was expected to take.
y equals one fourth times x minus thirty
y = 4x − 30
y equals one fourth times x plus thirty
y = 4x + 30
Answer:
option C
Step-by-step explanation:
We know that the toll road is 4 times faster than the side streets.If 'x' represents the number of minutes she usually spend taking the side streets. The represents the time she takes taking the toll road.Also we need to create an equation to represent her total travel time, including wait time

Twice a number added to another number is 15. The sum of the two numbers is 11. Find the numbers. Write the numbers from least to greatest
Answer:
4 and 7
Step-by-step explanation:
There are probably several ways to do this but this is how I did it:
First, I listed all the number combinations, that added together equaled 11.
This is what it looked like:
1, 10
2, 9
3, 8
4, 7
5, 6
6, 5
7, 4
I stopped here since the next step would be to double the first number and 8*2 would already be more than 15.
Then, I doubled the first number and added the second number to it, when I saw that didn't equal 15, I eliminated that possibility and moved on to the next set of numbers. When I reached 4, 7 I saw that 4*2 equaled 8 and 8 plus 7 equals 15 so I had the answer.
There are probably much more efficient ways to do this but this is how I did it.
Hope it helped!
The first number is 4 and second number is 7.
Let us consider that first number is x and second number is y.
[tex]2x+y=15\\\\x+y=11[/tex]
Substitute [tex]y=11 - x[/tex]in equation [tex]2x+y=15[/tex]
[tex]2x+11-x=15\\\\x=15-11=4[/tex]
So, [tex]y=11-x=11-4=7[/tex]

b) If (a - b) = 4 and ab = 2, find the value of a² + b².
Answer:
20
Step-by-step explanation:
note that
(a - b)² = a² + b² - 2ab , thus
a² + b² - 2ab = (a - b)² ( add 2ab to both sides )
a² + b² = (a - b)² + 2ab = 4² + 2(2) = 16 + 4 = 20
