Answer:
287.1 inches of the canvas.
Step-by-step explanation:
To solve this, we need to first figure out the total area of the canvas. To do that, multiply width by height.
29*33=957
Now set up your equation for solving for the area of the canvas that the rose covers.
x/957=30/100
We did it where: x is the area of the rose covers, 957 is the amount of inches that the canvas takes up, and the right side of the equation is the percent.
Now cross multiply.
100x=28,710
Now divide both sides by 100.
x=287.1
The red rose covers 287.1 inches of the canvas.
Answer:
7 sweets
Step-by-step explanation:
This is because the constant of proportionality is 7 since 35/5 since it is the ratio for Natasha. Since 7 is the constant of proportionality, you multiply it by the difference of the ratios. In this case, Natasha and Henry have a difference of 1 in ratios. Since it is a difference of 1, you multiply that by the constant of proportionality, 7. 7 X 1 is equal to 7, so Natasha gets 7 more sweets than Henry.
The answer to the question
a tennis ball has a diameter of about 2.5 inches
so volume of a tennis ball is: 4/3 x pi x r^3 = 8.2 cubic inches ( estimating you could say 8 cubic inches
1 cubic foot = 1728 cubic inches
so you could fit 1728/8 = 216 tennis balls in a cubic foot.( estimated)
you would then need to calculate the volume of the room
lets say a small room is 9 foo by 9 foot by 8 feet high
9 x 9 x 8 = 648 square feet
now multiply the 216 by the square feet of the room
216 * 648 = 139,968tennis balls
now because they are round, there will be empty space around them
so you could estimate about 139,000 tennis balls would fit I a 9 x 9 room that is 8 feet high.
You didn't give the dimensions of the room, but this gives you the idea of how to estimate
