Answer:
3 years
Step-by-step explanation:
A=P( 1+rt)
A= Total amount
P= Principal
r = yearly interest
t= time in year
672=600(1+0.04t). Distribute
672=600+600x0.04t
72= 24t
t= 3 years
Answer:
1.5
Step-by-step explanation:
Because the triangle are similar, they possess a proportional relationship in which the one triangle's side length is dilated by a unknown factor (y) to make its corresponding counterpart. Using this knowledge we can make the following two equations
3y=7 & xy=x+2 y is the variable representing the dilation factor
y=7/3 find the value of y
x(7/3)=x+2 substitute the value y into the equation
7/3x =x+2 solve for x
4/3x =2
(3/4)(4/3x)=2(3/4) multiply by the reciprocal
x=1.5
Answer:
Step-by-step explanation:
The circle has diameter endpoints of ( 4, 8 ) and (10, 16 ).
The midpoint of the diameter is the center
The radius is the distance from the center to any point on the circumference.
The equation of the circle with center (h,k) and radius r is given by:
We plug in the values to get:
To find the amount of fabric used on red fabric (the even numbered sides), you will need to find the surface area of 3 out of the 6 faces. They are all cube, so when you find the area of one face, you have the area of all of them!
To find the area of one of the faces you will multiply the length of the edge by itself. In this case, 20 in. by 20 in.
20 x 20 = 400 square inches per face.
400 square inches x 3 red faces = 1200 square inches
You will need 1200 square inches of red fabric to cover the even numbered sides of the cube.
