Step-by-step explanation:

Last year a business had a profits of $8000.

5 times means $5\times8000$

= $40,000.

Hence, this year profits are $40,000.

How do i solve this

Sophie [7]

Step-by-step explanation:

You're given that ΔUVW is similar to ΔYZW. The tricky part is identifying which sides in ΔUVW correspond to which sides in ΔYZW.

The triangles share point W, so visually rotate one triangle around W until the two triangles align. That way, you can see that UW and ZW correspond to each other, and VW and YW correspond to each other.

Now you can find the scale:

VW / YW = 5/12

And you can write a proportion to find x:

UW / ZW = VW / YW

x / 64 = 5 / 12

x = 26 ⅔

If y varies directly with x when y=8,x=20 find the value of x when y=42

Alecsey [184]

The value of x is 105 when y=42

Step-by-step explanation:

A direct proportion means that the change in one quantity will also cause the change in other quantity

Given

y varies directly with x

x ∝ y

when the proportionality symbol is removed a proportionality constant is introduced

$x=ky\\k=\frac{x}{y}\\Putting\ y=8\ and\ x=20\\k=\frac{20}{8}\\k = \frac{5}{2}\\So,\ the\ equation\ will\ be\\x=\frac{5}{2}y\\Putting\ y=42\\x=\frac{5}{2}*42\\x=5*21\\x= 105$

The value of x is 105 when y=42

It you invest S500 at an annual interest rate of 10% compounded continuously, calculate the final

lord [1]

Answer:

Step-by-step explanation:

The formula for continuous compounding is

$A(t)=Pe^{rt}$ where A(t) is the amount after all the compounding is done, P is the initial investment, r is the rate as a decimal, and t is the time in years. Filling in our info:

$A(t)=500e^{(.1)(5)}$

First raise e to the product of that power to get

$A(t)=500(1.64872171)$

Multiply those numbers together to get A(t) = $824.36
