Frankie was thinking about her mother cutting up the
lasagna when she noticed a very useful connection.
She recognized that any fraction in which the
numerator and denominator are the same is equivalent
to 1. In addition, multiplying a number by 1 leaves that
number unchanged.
"WOW," she said, “I can use this idea to find a whole
bunch of equivalent fractions!” She showed her team
the work below. “Look!" she said, “It's the same as
using a GIANT ONE!”
Answer:
why cant she just be like "ooh yummy lasagna" and move on lol

please help im struggling with geometry
WILL GIVE BRAINLIEST BUT YOU HAVE TO EXPLAIN
Given:
A geometric figure.
To find:
The point of tangency in the given figure.
Solution:
We know that, the point of tangency is a point where the tangent line touches the curve.
From the given figure it is clear that, two lines touch the circle at R and Z.
These two lines are tangent and they touch the curve at points R and Z. So, R and Z are point of tangency.
Therefore, the correct option is C.

The length of each side of a square is 6 feet more than the length of a side of a regular Octagon. The perimeter of the square is equal to the octagon. Find the length of the square and the length of a side of the octagon.
Please show work, I will give brainliest.
9514 1404 393
Answer:
square: 12 ft sidesoctagon: 6 ft sidesStep-by-step explanation:
This problem can be worked in your head.
If the perimeters of the square and regular octagon are the same, the side length of the 4-sided square must be the same as the length of 2 sides of the 8-sided octagon. Since the side of the square is 6 ft more than the side of the octagon, each side of the octagon must be 6 ft, and each side of the square must be 12 ft.
__
We can let s represent the side length of the octagon. Then we have ...
8s = perimeter of octagon
4(s +6) = perimeter of square
These are equal, so ...
4(s +6) = 8s
s +6 = 2s . . . . . . divide by 4
6 = s . . . . . . . . . . subtract s
The octagon has 6-ft sides; the square has 12-ft sides.

Printer A prints 36 pages every 1.5 minutes. Printer B prints 114 pages every 3 minutes.
Printer C prints 115 pages every 5 minutes Which printer prints the fastest?
Answer:
printer A- 36/1.5
printer B- 114/3
printer C- 115/5
first, multiply 1.5 x 10, 3 x 5, and 5 x3
you should get 15 for each.
once you have the denominators all done, multiply the numerators by the value you multiplied the denominator by and you should have your answer.
so all in all, printer B prints the fastest

A construction company is starting to build a new house. They need to put tape around the site to begin. The new home site is 202020 meters wide by 404040 meter long rectangle. The company already has 100100100 meters of tape. How much more tape does the company need to tape the site?
Answer:
20 meters
Step-by-step explanation:
A construction company is starting to build a new house. They need to put tape around the site to begin. The new home site is 20 meters wide by 40 meter long rectangle. The company already has 100 meters of tape. How much more tape does the company need to tape the site?
We would have to find the perimeter of this rectangle
Perimeter fo a rectangle = 2L + 2W
In the above question,
L = Length = 40 m
W = Width = 20 m
Hence:
Perimeter = 2(40m) + 2(20m)
= 80m + 40m
= 120m
Hence, he would need 120 meters of tape
From the above Question, the company already has 100m
Hence, the amount of tape that the company needs more =
120m - 100m = 20 m
Heather works at the library. Her weekly income is directly proportional
to the number of hours she works. Last week she worked 16 hours and
earned $116. How much would she earn if she could work 20 hours?
Answer:
$145
Step-by-step explanation:
When you do this type of problem, you want to find the unit rate. In order to do that you divide $116 by 16, and you get $7.25 (how much she make in one hour). Then you multiply $7.25 by 20, and get $145.
Answer:
Step-by-step explanation:
You are the president of an interior design company. You pay a part-time designer
$200 per week, plus $25 for each completed design. Write an equation to represent this
situation. Use this equation to determine how many completed designs you can have per
week if your weekly design budget is $800?
Answer: 24
Step-by-step explanation:
Okay, so if the part-time designer gets 200 dollars per week, we should subtract 200 by 800.
800 - 200 = 600.
Then we divide 600 by 25, and that will be the amount of completed designs we'll be able to have each week.
600 ÷ 25 = 24.
So in conclusion, you can pay the designer $200 per week and get 24 completed designs from him.
Hope this helps!
Anybody know this question
Here as by the given information ,
♦ sinA = Opposite/Hypotenuse
♦ cosA = Adjacent/Hypotenuse
♦ TanA = Opposite/adjacent
So here we need to find the same for angle B so we need to use the same formulas for angle B also .
→ sinB = Opposite/Hypotenuse = 12/13
→ cosB = Adjacent/Hypotenuse = 5/13
→ tanB = Opposite/Adjacent = 12/5
Decrease 65kg by 3/5
Step-by-step explanation:
answer........ . . .......
Answer:
26kg
Step-by-step explanation:
Firstly, we need to find 1/5 of 65kg so we do: 65/3=13
Then, to find 3/5 of 65kg we multiply 13*3 to get 39
Lastly, we subtract 39 from 65 to get 26kg
what is responsible for the blue sky
Answer:
I think that it is something to do with the atmosphere and the way that the light bounces around it. Here is some information from a website to back this up. "The Short Answer: Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves."
Answer:
the blue sky is caused by sunlight reaching earth atmosphere which is scattered by the gases and air particles. which blue light is scattered more so that is why the sky is blue

Step-by-step explanation:
the mean (average) of three boys is 40 pounds. one of the boyd weighs 50 pounds. the other two boys have the same weight. find weight of each of the boys
Answer:
35, 35, and 50
Step-by-step explanation:
50 + x + x = n
n ÷ 3 = 40
n = 40 x 3
n = 120
50 + 2x = n
50 + 2x = 120
2x = 120 - 50
2x = 70
2x/2 = 70/2
x = 35
To check:
35 + 35 + 50 = 120
120 ÷ 3 = 40
Hope this helps
Answer:
35
Step-by-step explanation:
let us take each boy's weight as x
therefore,
average = [tex]\frac{x+x+50}{3\\}[/tex]
40 = [tex]\frac{x+x+50}{3\\}[/tex]
40 x 3 = x + x + 50
120 - 50 = 2x
70 = 2x
2x = 70
x = [tex]\frac{70}{2}[/tex]
x = 35
So weight of each boys is 35.
A tree measured 18 1/2 feet tall. Over the next 7 1/2 years, it grew to be 63 1/2 feet tall. During the 7 1/2years, what was the average yearly growth rate of the tree?
Step-by-step explanation:
first subtract how tall is was 7 1/2 years ago from hell with all it is now. 57 - 40.5 = 16.5 or 16 1/2 so and the seven and a half years the tree Grace 16.5 with 16 1/2 seats to get the average yearly growth for the 7 1/2 year. You have to divide 16 and 1/2 ft by 7 and 1/2 Tim Wiles it makes it much easier if you change the fractions to decimals

Polynomial Roots Calculator is a set of methods aimed at finding values of m for which F(m)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers m which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 3 and the Trailing Constant is 1.
The factor(s) are:
of the Leading Coefficient : 1,3
of the Trailing Constant : 1

The Factor Theorem states that if P/Q is root of a polynomial then this polynomial can be divided by q*x-p Note that q and p originate from P/Q reduced to its lowest terms

Cassie bought 2 apples for $4. Olivia bought 5 apples for $15. How much more money did Oliva spend per apple? Use the dollar sign!
Answer:
$1
Step-by-step explanation:
To find out how much more money Olivia spent per apple, we need to find out how much each spent on one apple.
Cassie:
2 apples --- $4
1 apple --- $4 ÷ 2 = $2
Olivia:
5 apples --- $15
1 apple --- $15 ÷ 5 = $3
Difference per apple = $3 - $2
= $1

Which of the following numbers has the same absolute value as 86?
A.-86
B.0
C.-172
D.-43
Answer:
A. -86
Step-by-step explanation:
The absolute value is the distance a number has from zero.
Two numbers that are the same, except that one is positive and negative, will have the same absolute value.
So, -86 and 86 have the same absolute value of 86. This is because they are both 86 away from 0.
So, A is the correct answer.
