Answer:
39 dimes
Explanation:
From the graph:
• Total number of nickels = 9+4+7=20
,
• Total number of dimes = 7+10+9 = 26
The ratio of total nickels to total dimes = 20:26
If the total number of nickels the students donate is increased to 30, we have:
We then solve for x:
The number of dimes they should donate to keep the ratio of total nickels to total dimes the same is 39.
The two square roots are 20 and -20
To let u know if it is either equal to or not
Answer:
15.22
Step-by-step explanation:
The equation of the circumference of a circle is 2(pi)r
This is actually because 2pi is angle of the arc that makes up the full circle (radians of course)
so a simple formula is:
arc length in radians X radius
radius = 4 cm
the area that the question wants is the oposite
of the 142 degree section so 360 - 142 = 218
218 degrees * (pi/180) = 3.80482 rad
3.80482 * 4 = 15.21928 cm
Answer:
150 bags
Step-by-step explanation:
Given the total area:
The area will be:
=75*50
= 3750 square feet
As it is given that one bag covers 25 square feet. To find the total number of bags we have to find how many 25s will be in 3750 square feet.
So,
Total number of bags = 3750 / 25
= 150 bags
Hence, total number of bags that will be used are 150 ..
