Joe collected 94 stamps altogether. He collected 27 in April and 34 in May. How many did he collect in June?
Answers
Answer:
33
Step-by-step explanation:
From what we know in April and May combined Joe has collected 61 stamps (27+34=61). To then work out how many Joe collected in June you would take the 61 we know he has already got away from the grand total of 94 (94-61=33) this means in June he collects 33 stamps. Hope this helps :)

You will now consider Option 2-using low-flow shower heads instead of regular
shower heads.
Courtney claims that Option 2 would result in the class using 270 gallons of
water during 180 minutes of showering because:
(180minutes) (1.5gallons per minute) = 270gallons.
=
Courtney is incorrect.
• Identify her error.
• Explain how to find the correct amount of water used if the class
chooses Option 2.
• Include how much water would be used.
Answers
The error in Courtney claims that Option 2 would result in the class using 270 gallons is that he multiplied rather than dividing.
How to solve the error?From the information given, it should be noted that Courtney claims that Option 2 would result in the class using 270 gallons of water during 180 minutes of showering is incorrect because she should have divided and not multiplied. This will be:
= 270 / (3/2)
= 180 × 2/3
= 120
Therefore, 120 gallons will be used.

Elaina has to congruent rugs at her house she cut one vertically down the middle and she cut diagonally though the other one after making the cuts which rug has the lager area i need the answer fast
Answers
Answer:
All of the rugs are the same size after making the cuts. The vertical line goes down the center of the rectangle, making two congruent parts. The diagonal line also splits the rectangle into two congruent parts because the area of a right triangle is exactly half the area of the rectangle.

Graph the line with slope 2 passing through the point (-1, 5).
Answers
Answer:
(-1,5)
(0,7)
(1,9)
(2,11)
(3,13)
(4,15)
(5,17)
Step-by-step explanation:
Because we are already given our slope and a point to help us create our line. With this information, we can find the other points that we would use to create the line for a slope = 2 passing through the point (-1, 5).
To do so we use the information that is a slope equal [tex]m=\frac{rise}{run}[/tex]
So we make our slope which is two look like [tex]m=\frac{2}{1}[/tex]
So to find our next point we would have to rise up 2 units and run 1 unit to the right from (-1, 5). We do the same to find the next points.
We get the following points from doing so
(0,7)
(1,9)
(2,11)
(3,13)
(4,15)
(5,17)
You will use the points to create the line for the slope 2 passing through the point (-1, 5)

Several ways to figure it out, but hopefully one of these is better for you to understand..
20 is half of 40 or 50% 50% in decimal form is .5 or .50 (either way works)
40 x .5 = 20 or you could say
1/2 of 40 is 20

For a rotation of 180° clockwise or counterclockwise, the x and y will always be the opposite. For instance, if coordinates (4, 7) are being 180° rotated, the new set of coordinates will be (-4, -7).
Remembering the rule, the final answer to your question is A, 180° clockwise rotation about the origin.

Answers
Answer:
4
Step-by-step explanation:
So, 5/15 shirts are gray.
This can be simplified to 1/3. (5÷5 = 1, 15÷5=3)
So taking this data into account, if we have 12 shirts, one third of them should be gray. So, 12/3 = 4.

2. split the area into a rectangle and triangle (see red line)
3. find the area of the triangle
a. find the base (2)
b. find the height (2)
area = base * height / 2 = 2 * 2 / 2 = 2
4. find the area of the rectangle
a. find the width
the width can be found from the right triangle at the top right. the height is 2 and the bottom leg is 1, so using the pythagorean theorem, the hypotenuse, which is the width of the triangle, equals
√(2²+1²) = √5 as our width
b. find the length
given the top right triangle, we have a height of 5 and another leg length of 5, so the length = √(5²+5²) = √50
the area of the rectangle is thus √50 * √5 = √250
4. the area is thus the two areas added up, or √250 + 2

Answers
The total number of children in Stephan's school prefer pepperoni pizza where 375 children in Stephan's school is 310.
What is equivalent ratio?Equivalent ratio is the ratio which is same in the value as the original ratio, but the numerator and denominator is different for both the ratios.
Stephan read that 62 out of every 75 children prefer pepperoni pizza. Thus, the ratio of children who prefer pepperoni pizza to the total children is,
[tex]n=\dfrac{62}{75}\\[/tex]
Let suppose there are x children in Stephan's school prefer pepperoni pizza. There are 375 children in Stephan's school. The ratio of children who prefer pepperoni pizza to total 375 children is,
[tex]\dfrac{x}{375}[/tex]
Both the above ratio are for the same condition, and are equivalent ratio. Thus,
[tex]\dfrac{x}{375}=\dfrac{62}{75}\\x=\dfrac{62}{75}\times375\\x=310[/tex]
Thus, the total number of children in Stephan's school prefer pepperoni pizza where 375 children in Stephan's school is 310.

What is the mean absolute deviation of a data-set?The mean of a data-set is given by the sum of all observations divided by the number of observations.The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.The mean absolute deviation represents the average by which the values differ from the mean.Hence, lower values of the mean absolute deviation means that the scores are closer, and thus his scores were closest together in Math.
