A graduated cylinder is basically a cylinder with little measurements on it.
If we drop the ball into the cylinder and the final volume in 29 instead of 20, this means that the ball has a volume of 9 mL as it took up 9mL of the water, pushing it up 9 mL.
Density is mass divided by volume. The ball has a mass of 27 g and a volume of 9mL. So, the density is 3 g/mL.

Simplify both sides of the following equation as much as possible, and then solve:
10 – 11w + 12w = -2
Answer:
w = -12
Step-by-step explanation:
10 – 11w + 12w = -2
Combine like terms
10 +w = -2
Subtract 10 from each side
10+w-10 = -2-10
w = -12
Answer:
w = -12
Step-by-step explanation:
10 – 11w + 12w = -2
10 + w = -2
subtract 10 on both sides
w = -12

Name three different ways you can represent a group of equivalent ratios
At the candy store there are 420 gumdrops and 280 chocolate bars, for a total of 700 candies all together. What is the ratio of candies to chocolate bars? (
Answer:
5 : 2
Step-by-step explanation:
Given that:
Number of gumdrops = 420
Number of chocolate bars = 280
Total Number of candies = 700
To find:
The ratio of candies to chocolate bars = ?
Solution:
First of all, let us discuss the method to find the ratio of any two quantities.
Suppose, we need to find the ratio of two numbers [tex]p[/tex] and [tex]q[/tex].
Then to find the ratio [tex]p:q[/tex] , we need to divide p by q and represent it in the simplest form [tex]\frac{a}{b}[/tex] such that a and b can not be divided further.
Here, to find the ratio of candies to chocolate bar:
[tex]Ratio = \dfrac{\text{Number of candies}}{\text{Number of chocolate bars}}\\\Rightarrow \dfrac{700}{280}[/tex]
Here, we can simplify the fraction by dividing the numerator and denominator by 10 first:
[tex]\dfrac{70}{28}[/tex]
Now, let us divide the numerator and denominator by 14:
[tex]\dfrac{5}{2}[/tex]
So, the ratio is 5 : 2
Question
If one big rectangle represents "one whole", what fraction of area is shaded gold in the two rectangles?
Enter your answer as an improper fraction, NOT a mixed number.
Submit Question
Answer:
15/8
Step-by-step explanation:
one big rectangle is 1 or 8/8 and the other is 7 out of 8, therefore we have 8/8+7/8 = 15/8.
You are required to find the fraction of the rectangle shaded gold in the two rectangles
The fraction that was shaded in the two triangles is 15/8
Each of the rectangles are divided into 8 equal parts
The first rectangle has 8 equal sections
The second rectangle also has 8 equal sections
out of the 8 equal sections in the first rectangle, 8 was shaded gold
Then, we have 8/8 shaded = 1 whole
out of the 8 equal sections in the second rectangle, 7 was shaded gold
Then, we have 7/8 shaded
Improper fraction is a fraction in which the numerator (top number) is greater than or equal to the denominator (down number)
Therefore, rectangle 1 + rectangle 2
= 8/8 + 7/8
= (8+7) / 8
= 15/8

What is the prime factorzation of 54
Answer:
2*3*3*3
Step-by-step explanation:
Answer:
54 = 2×3^3
Step-by-step explanation:
Factor the following integer:
54
Hint: | Is 54 divisible by 2?
The last digit of 54 is 4, which means it is even. Therefore 54 is divisible by 2:
54 = 2 27:
54 = 2×27
Hint: | Now try to factor 27. Is 27 divisible by 2?
27 is not divisible by 2 since 27 is odd and 2 is even:
54 = 2×27 (27 is not divisible by 2)
Hint: | Is 27 divisible by 3?
The sum of the digits of 27 is 2 + 7 = 9, which is divisible by 3. This means 27 is divisible by 3:
27 = 3 9:
54 = 2×3×9 (9 is not divisible by 2 since 27 is not)
Hint: | Now try to factor 9. Is 9 divisible by 3?
9 = 3 3, which means 9 is divisible by 3:
9 = 3 3:
54 = 2×3×3×3 (3 is not divisible by 2 since 9 is not)
Hint: | Now try to factor 3. Is 3 prime?
No primes less than 3 divide into it. Therefore 3 is prime:
54 = 2×3×3×3
Hint: | Express 54 as a product of prime powers.

What is 36/81
in simplest form? HELP!
Answer:
4/9
Step-by-step explanation:
To simplify this fraction, we can find the factors for each number and then take an equal amount out (divide).
Two factors that make up 36 are 4 and 9. Two factors that make up 81 are 9 and 9. Therefore, because 9 is a common factor between the two, we can divide both terms by 9 and simplify the fraction.
36/9 = 4
81/9 = 9
The new fraction is 4/9.

Solve this problem. A florist sells holiday bouquets that use roses and carnations in a ratio of 2 to 7. She receives a shipment of 343 carnations. How many roses will the florist need
Let roses be R and carnations be C
"in a ratio of 2 to 7" means that the ratio of R to C is 2 to 7, meaning you'll have to cross multiply to translate it algebraically
[tex]R:C\\2:7\\7R=2C\\[/tex]
since C = 343 we plug 343 in [tex]7R=2C[/tex]:
[tex]7R=2(343)\\7R=686\\R=\frac{686}{7} \\R=98[/tex]
ergo, she needs 98 roses
to make sure of the answer:
"ratio of 2 to 7" is technically a fraction => [tex]\frac{2}{7}[/tex]
and since the ratio of the roses to the carnations is the same as [tex]\frac{2}{7}[/tex] we plug the values R = 98 and C=343:
[tex]\frac{R}{C}=\frac{98}{343}=\frac{2}{7}[/tex]

The results of a recent survey of the students at Rockdale Middle School show that 17 out of every 22 students enjoy the cafeteria’s cheeseburgers, "5" /"6" of the students enjoy the cafeteria’s pizza, and 80.5% enjoy the cafeteria’s salad bar. Based upon this survey, which of these three foods is most enjoyed?
Answer:
Pizza is the most enjoyed food with 83.3%
Step-by-step explanation:
Given
Cheeseburgers = 17 out of 22 students
Pizza = 5/6
Salad Bar = 80.5%
Required
Which of the food is most enjoyed
First, we have to convert all goven parameters to percentage
[tex]Cheeseburgers = \frac{17}{22}[/tex]
[tex]Cheeseburgers = 77.3\%[/tex]
[tex]Pizza = \frac{5}{6}[/tex]
[tex]Pizza = 83.3\%[/tex]
Comparing the percentages;
Pizza is the most enjoyed food with 83.3%
True or false: equilateral triangles can be classified as acute right or obtuse
Answer:
it is only acute
Step-by-step explanation:
False: equilateral triangle has 3 equal sides and 3 equal angles measure 60 degrees
Answer:
True
Step-by-step explanation:
In an equilateral triangle, all sides are equal in length.
That means that all the angles of the triangle will be congruent.
Since a triangle has 3 angles that always add up to 180 degrees, each angle is 60 degrees.
(180/3=60)
A right triangle must have one 90 degree angle.
An obtuse triangle must have an angle that is greater than 90 degrees.
An acute triangle's angles must all measure 89 degrees or less.
Hence, the given statement is true.
Equilateral triangles can be classified as acute.
Match the measureable quantity given by its formula with the appropriate unit(s).
