Suppose there is a rectangle with a width and length of x and y. The area would be xy.
A rectangle with width and length 2x and 2y would have an area of 4xy.
In essence, when you multiply the lengths by 2, the area multiplies by 2 SQUARED.
4(4(x+3)) = 16(x+3).
The ratio will be the same for any value of x because the area is still being multiplied by the same 2².
Answer:
y-5=3(x-4)
Step-by-step explanation:
y-y1=m(x-x1)
m=3
y-5=3(x-4)
The shape shown is a cone and the cones perpendicular cross section is a triangle.
If you need the parallel cross section then it will be a circle.
The answer is A.
Hope this helps :)
Answer:
Step-by-step explanation:
The formula for simple interest is Prt = I, where P is the initial investment, r is the interest rate in decimal form, t is the time in years, and I is the interest earned from the multiplication of the 3 previous values.
Our p value is 80; our r in decimal form is .024, and our t is 1.5. Multiplying those together,
80(.024)(1.5) = $2.88
The monthly interest rate to earn the same amount of interest during the same amount of time, assuming you are investing $80, would not change. It would be 2.4%.
