Total right away tells me we are adding. To Find distance, you multiply speed times time. So Jethro's distance is 3 x 2 and Randy's distance is 4 x 3. Then we add these.

10? Unless I am mistaken, it is 1 second per strike. 10 strikes, 10 seconds.

This is a similarity problem. It basically is saying 1:30 means for every 1 cm we have, you get 30 cm. This is easier than other problems since it is 1:30 and not weird like 5:9. So we can basically multiply each of the given dimensions by 30, and...

a sales tax rate is 7.5% if the tax on a purchase is 9.75 what was the price of the purchase (answer)

(Sale Price) x (Sales tax rate) = tax You are missing the Sale price so we will use P in place of that. P x 7.5% = 9.75 Rewrite 7.5% as a decimal. 0.075 P x 0.075 = 9.75 Since we are solving for P,...

Let's start with the numerator(top). 27-2/3 means the cubed root of 27, then squared, then moved to the denominator because the exponent is negative. The cubed root of 27 is 3. squared it becomes 9. and the negative exponent makes it 1/9. (the 1 appears because something...

I am getting f'(x) = 2xe^(x2+1). Is that what you got? Next you will have to use product rule. (Derivative of 2x) times e^(x2+1) + 2x times (Derivative of e^(x2+1)) I got f''(x) = 2e^(x2+1) + 4x2e^(x2+1) Notice...

x = r cosθ y = r sinθ r = -3 θ = 120o Plug them in a calculator and then write your answer as ( x, y). If you are not able to use a calculator, then you will need to graph the line which will end up in Quadrant 4. If you create...

Property sold for 65,000. Listing agreement indicates the commission for the property is 5.5% (answer)

It is not very clear on who is getting what amounts. I am going to assume that the sales associates company gets 5.5% and 6.5%, and then the sales associate gets 25% of that. First, half of 65000 is 32,500. So the company will earn 5.5% of 32,500 and 6.5% of the other 32,000. 5...

trigonometric identities (answer)

Hello, unfortunately trig identities take time and depend on the problem. Trig identities are like proofs where there is no one method that will solve all of them or even the next one. Only time and a lot of practice will help you understand it. Here are some pointers I give...

PROBABILITY PLZ HELP:( (answer)

P(K,K) = (4/52) *(4/52) = 1/169 P(D, 8) = (13/52) * (4/52) = 1/52 P(4S, KD) = (1/52)*(1/51) = 1/2652 NOTE: denominator must decrease since there is one less card in the deck. P(K, Q) = (4/52) * (4/51) = 4/663

Help please (answer)

We will say x is how much they will place into Cert. of Dep. and therefore (180,000 - x) is what they will place into AA bonds. Since the Cert of Dep yields 7% then they earn 0.07 times x. Since the AA bonds yield 11%, then they earn 0.11 times (180,000 - x). Since...
