7:5 = 21:15
explanation : to get 21, multiply 7 by 3. since 7 is multiplied by 3, then you multiply 5 by 3 too. and you get 15.
Answer: 7.7%
Step-by-step explanation: First find the increase in height by subtracting 52 from 56. 56-52=4.
To find what percent this is of 52, divide 4 by 52. 4/52=0.0769. Then convert this from a decimal to a percent by multiplying by 100. 0.0769*100=7.69.
I just rounded it to the nearest tenth, you can change it how you need to.
Answer:
X= 2
y = 2
Step-by-step explanation:
y=-2x+6............... equation 1
y=3x-4................... equation 2
from equation 2
y=3x-4
substitute y=3x-4 in equation 1
3x-4=-2x+6
collect like terms
3x+2x=6+4
5x=10
divide both sides by 5
X=2
substitute X=2 in equation 1
y=-2x+6
y=-2(2)+6
y=-4+6
y=2
hope it helps
Answer: Area of cross section would be 4 square units.
Step-by-step explanation:
Since we have given that
Area of base of cone = 16 sq. units
Height = 10
We need to find the area of cross section that is distance 5 from the vertex.
So, Height of cross section = 5 units
total height of cone = 10
It means the cross section is half of the whole cone.
So, it becomes,
Hence, Area of cross section would be 4 square units.
B. Because the absolute value of a number is the distance of that number from 0.
