Answer: [tex]12\ \text{min}[/tex]
Step-by-step explanation:
Given
It takes 20 min and 30 min for a person and his friend to paint a wall individually i.e.
In 1 min they cover [tex]\frac{1}{20}[/tex] part and [tex]\frac{1}{30}[/tex] part of wall respectively.
If the work together, 1 minute work is
[tex]\Rightarrow \dfrac{1}{20}+\dfrac{1}{30}\\\\\Rightarrow \dfrac{3+2}{60}\\\\\Rightarrow \dfrac{5}{60}[/tex]
Time required will be reciprocal of it
[tex]\Rightarrow \dfrac{60}{5}=12\ \text{min}[/tex]

solve 3x-y=7 for x if weird answer will report
Answer:
x = 1/3y +7/3
Step-by-step explanation:
3x-y=7
Add y to each side
3x-y+y=7+y
3x = y+7
Divide each side by 3
3x/3 = y/3 + 7/3
x = 1/3y +7/3
Answer:
x= 7/3 + y/3
Step-by-step explanation:
divide each term by 3 and simplify

y = 51.32º
Step-by-step explanation:
z = 180 - 47 - 90
z = 43º
sin43 = opp/hyp
sin43 = 35/y
y = 35/sin43
y = 51.32º

Answer:
y = x+2
Step-by-step explanation:
proportional relationships are of the form
y = kx where k is a constant
y = x is proportional with k=1
y = 2x is proportional with k =2
y = x+2 is linear
Answer:
y = x+2
Step-by-step explanation:
proportional relationships are of the form
y = kx where k is a constant
y = x is proportional with k=1
y = 2x is proportional with k =2
y = x+2 is linear
Dorian buys one 32-ounce can of purple paint witha red to blue ratio of 3 to 5. He buys a 25-ouncee can of a different shade of purple paintwith a red to blue ratio of 3 to 2. Dorian mixes the two cans together. What is the ratioof red paint to blue paint in Dorian's new mixture?
Answer:
9 : 10
Step-by-step explanation:
For 32 ounce- can
Dorian buys one 32-ounce can of purple paint with a red to blue ratio of 3 to 5.
The sum of proportion = 3 + 5 = 8
The number of ounces of red paint = 3/8 × 32-ounce = 12 ounces
The number of ounces of blue paint = 5/8 × 32-ounce = 20 ounces
For 25 ounce can
He buys a 25-ounce can of a different shade of purple paint with a red to blue ratio of 3 to 2.
The sum of proportion = 3 + 2 = 5
The number of ounces of red paint = 3/5 × 25-ounce = 15 ounces
The number of ounces of blue paint = 2/5 × 25-ounce = 10 ounces
Dorian mixes the two cans together.
The total ounces for red paint
= 12 ounces + 15 ounces = 27 ounces
The total ounces for blue paint
= 20 ounces + 10 ounces = 30 ounces
Hence, the ratio of red paint to blue paint in Dorian's new mixture is
Red : Blue
27 ounces : 30 ounces
9 : 10

Calculate the interquartile range from the given box plot
Answer:
IQR = 3
Step-by-step explanation:
The interquartile range (IQR) is the difference between the upper quartile Q₃ and the lower quartile Q₁
Q₃ is the value at the right side of the box , that is Q₃ = 62.5
Q₁ is the value at the left side of the box. that is Q₁ = 59.5
Then
IQR = Q₃ - Q₁ = 62.5 - 59.5 = 3

Answer:
Mode :6 Range :5
Step-by-step explanation
To find the mode look for the number that is repeated the most times. And to find the range subtract the greatest number with the smallest number. Hope this helped :)
Step-by-step explanation
The range is the max value minus the minimum value, which would be 8-3, and that equals 5
and the mode is the number that you see the most in a data set, in this case the mode would be 6 since it is the only number that occurs three times
