What is the value of x? A. 2 Units B. 3 Units C. 5 Units D. 8 Units

Fudgin [204]

You need the formula for geometric mean for right triangles as it applies to the altitude. For us, that formula will be $\frac{BD}{AD}=\frac{CD}{BD}$ where BD is your altitude. The formula then, filled in accordingly, would be $\frac{10}{x}=\frac{4x}{10}$ . We cross multiply to get that $4x^2=100$ . Divide both sides by 4 to get $x^2=25$ , so x = 5. Choice C is the one you want.

Answer:

162km

Step-by-step explanation:

dis=30km

time=5/12hr

speed =(dis÷time)

30÷5/12

30×12/5=72km/h

sp=72km/h

time=21/4hr

dis= sp×time

72×9/4=162km

3400 dollars is placed in an account with an annual interest rate of 8.25%. How much will be in the account after 25 years, to t

Mice21 [21]

$A = S(1+r)^{t}$ is the formula for an annual interest rate.

A = the future amount
S = initial amount
r = rate of interest
t = time in years

Now plug in all variables into the equation.

$A = 3400(1+.0825)^{25} = 24670.419$

To the nearest cent would be rounding the answer to the nearest hundredth.

$24670.419 = $24670.42$

The answer is $24670.42

Write a fraction on the blank to make the comparison true .Use the fractions form the box .Explain how you choose your number 3/

Lelechka [254]

Answer:

Explained

Step-by-step explanation:

So I'm not sure if you mean by 3/4 or 3-4. But I'm going to assume that its 3-4 because 3/4 is greater than 3/5

3/5 is equal to 0.6 -> you can also find 0.6 by multiplying 3/5 * 2 on both sides which will be 6/10 which is 0.6

and 3-4 is - 1 (which is negative)

since 3/5 is positive and 3-4 is negative. You would know that this is true.
