Answer:
6 Oranges and 2 bottles of juice.
Step-by-step explanation:
For the amount of oranges: 18÷3=6 (take 1/3 of 18).
For the bottles of of Juice: 18÷9=2 (take 1/9 of 18).
in this question, if the numerator is 1, then just divide the number of girls by the denominator (eg. 3 and 9 in this case).
There are six oranges and two bottles of juice will she needs for all 18 girls.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
For example 4/2 = 2
There are the total number of girls is 18. Each girl will eat 1/3 of an orange and one serving of juice, or 1/9 of the amount in a bottle.
To determine the number of oranges and the bottles of juice.
We have to divide the number of girls by the denominator (eg. 3 and 9 in this case).
For the number of oranges:
1/3 of 18
18 ÷ 3
18 / 3 = 6
For the bottles of Juice:
1/9 of 18
18 ÷ 9
18 / 9 = 2
Hence, there are six oranges and two bottles of juice will she needs for all 18 girls.

8 1/6 * 2^2 = 32 1/2
Work out the exact value of x.
Answer:
For short Go all the down
Conversion a mixed number 8 1/4
to a improper fraction: 8 1/4 = 8 1/4
= 8 · 4 + 1/4
= 32 + 1/4
= 33/4
To find new numerator:
a) Multiply the whole number 8 by the denominator 4. Whole number 8 equally 8 * 4/4
= 32/4
b) Add the answer from previous step 32 to the numerator 1. New numerator is 32 + 1 = 33
c) Write a previous answer (new numerator 33) over the denominator 4.
Eight and one quarter is thirty-three quarters
Conversion a mixed number 3 2/5
to a improper fraction: 3 2/5 = 3 2/5
= 3 · 5 + 2/5
= 15 + 2/5
= 17/5
To find new numerator:
a) Multiply the whole number 3 by the denominator 5. Whole number 3 equally 3 * 5/5 = 15/5
b) Add the answer from previous step 15 to the numerator 2. New numerator is 15 + 2 = 17
c) Write a previous answer (new numerator 17) over the denominator 5.
Three and two fifths is seventeen fifths
Subtract: 33/4
- 17/5
= 33 · 5/4 · 5
- 17 · 4/5 · 4
= 165/20- 68/20
= 165 - 68/20
= 97/20
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(4, 5) = 20. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 4 × 5 = 20. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - thirty-three quarters minus seventeen fifths = ninety-seven twentieths.
Conversion a mixed number 2 1/3
to a improper fraction: 2 1/3 = 2 1/3
= 2 · 3 + 1/3
= 6 + 1/3
= 7/3
To find new numerator:
a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/3
= 6/3
b) Add the answer from previous step 6 to the numerator 1. New numerator is 6 + 1 = 7
c) Write a previous answer (new numerator 7) over the denominator 3.
Two and one third is seven thirds
Subtract: 7/3 - 1/4
= 7 · 4/3 · 4 - 1 · 3/4 · 3
= 28/12- 3/12
= 28 - 3/12
= 25/12
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(3, 4) = 12. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 4 = 12. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - seven thirds minus one quarter = twenty-five twelfths.
Subtract: the result of step No. 3 - the result of step No. 5 = 97/
20 - 25/12
= 97 · 3/20 · 3 - 25 · 5/12 · 5
= 291/60 - 125/60
= 291 - 125/60
= 166/60
= 2 · 83/2 · 30
= 83/30
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(20, 12) = 60. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 20 × 12 = 240. In the next intermediate step, , cancel by a common factor of 2 gives 83/30
In words - ninety-seven twentieths minus twenty-five twelfths = eighty-three thirtieths.
Step-by-step explanation:
83/30 is the awnser

A regular hexagonal prism has an edge length 11 cm, and height 8 cm. Identify the volume of the prism to the nearest tenth.
Answer:
it may be V ≈ 4191.6 cm3 so sorry if i'm wrong!!!
Step-by-step explanation:
Answer: V ≈ 2514.9 cm3
Step-by-step explanation:
To find the volume of the prism, first calculate the area of the base.
To find the apothem of the hexagonal base, recognize that the sum of the measures of the interior angles in a hexagon is (6−2)⋅180°=720°. So, the interior angle has measure 720°6/=120°.
The base angle of the triangles with the hexagon's sides as their base is one-half of 120°, or 60°. The apothem bisects these triangles to form two right triangles with the short leg length of 5.5 cm.
By the definition of tangent, tan 60°=?/5.5.
Solve for ?.
?=5.5 ⋅ tan 60°
Therefore, the apothem length equals 5.5 ⋅ tan 60°.
The area of a hexagonal base.
B=6⋅(12⋅11⋅?)
Substitute 5.5⋅tan60° for ?.
B=6⋅(12⋅11⋅5.5 ⋅ tan60°)
Simplify.
B=181.5 ⋅ tan60° cm2
The volume of a prism.
V=Bh
Substitute 181.5 ⋅ tan60° for B and 8 for h.
V=(181.5 ⋅ tan60°)⋅8
Multiply 181.5 by 8.
V=1452 ⋅ tan60°
Use a calculator to approximate.
V≈2514.9 cm3
Therefore, the volume of the hexagonal prism is approximately 2514.9 cm3.

b) The fraction of side is
YZ / AB = XY / AC= XZ / BC = 3/4.
c) Yes the similarity of Triangle.
What is Similarity?Similar triangles are triangles that have the same shape but differ in size. Similar items include all equilateral triangles and squares with any side length. In other words, if two triangles are identical, their corresponding angles and sides are congruent and in equal proportion. The " sign here denotes the resemblance of triangles.
In Triangle ABC and YZX
a) So, the pairs of proportional triangle is
AB and YZ,
AC and XY,
BC and XZ
b) The fractions with your side pairs is
YZ / AB = 30 / 40 = 3/4
XY / AC = 37.5 / 50 = 3/4
XZ / BC = 45/ 60 = 3/4.
c) As, the ratio of sides are proportion.
So, by SSS similarity criteria the triangles are similar.

What is the slope and y-intercept of the line?
Answer:
Slope = 3
Y-intercept = -2
Step-by-step explanation:
Points on the line: (0, -2) and (1,1)
Slope:
m=(y2-y1)/(x2-x1)
m=(1+2)/(1-0)
m= 3/1
m = 3
Slope-intercept:
y - y1 = m(x - x1)
y + 2 = 3(x - 0)
y + 2 = 3x
y = 3x - 2
y = mx + b, where

The scatter plot shows the average movie ticket prices since 1995.
write an equation in slope intercept form for the line that is drawn
use your equation to make a conjecture about the average cost of a movie ticket in 2020
Answer:
The average movie ticket prices in 2020 was $ 10.25.
Step-by-step explanation:
If (0 , 4) and ( 8, 6) are two points on a line, the slope of the line is:
m= y2 - y1/ x2 - x1
m= (6 - 4) / (8 - 0)
m= 1 / 4
The y-intercept is $ 4, meaning it is the average movie ticket price in 1995.
Therefore,
Y = mx + b
Y = 1/4 x + b
It is m= 1/4, interpreting the slope we have that for every additional 4 years the average movie ticket price will increase by $ 1.
The year 2020 is 25 years after 1995, then
Y= 1/4 (25) + 4
Y = $ 10.25
The average movie ticket price was $10.25 in 2020.

Answer:
Step 3
Step-by-step explanation:
Given the equation :
1/4(1/3k+9)=6
Step 1 : Olga multiplied both sides by 4
1/4(1/3k + 9) * 4 = 6* 4
1/3k + 9 = 24
Step 2 : Olga subtracted 9 from sides
1/3k + 9 - 9 = 24 - 9
1/3k = 15
Step 3 : Both sides should be multiplied by 3
1/3k * 3 = 15 * 3
k = 45
This is the step Olga made a mistake. Olga attempted to divide 15/3 = 5 instead of Multiplying 15 * 3 to obtain 45

What is 75% of 44 cookies
Answer: 33 cookies.
Step-by-step explanation: To find the 75% of 44 cookies, use these steps:
Step 1: Our output value is 44.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 44 = 100%.
Step 4: Similarly, x = 75%.
Step 5: This results in a pair of simple equations:
44 = 100%(1)x = 75%(2)Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right-hand side) of both equations have the same unit (%); we have:
[tex]\frac{44}{x} \\[/tex] = [tex]\frac{100 percent}{75 percent}[/tex]Step 7: Again, the reciprocal of both sides gives:
[tex]\frac{x}{44}[/tex] = [tex]\frac{75}{100}[/tex]x = 33Therefore, 75% of 44 is 33. Thus, it is 33 cookies.
