It should be 908.70 by my understanding

Convert the percentage to a decimal
30% = 0.3
multiply the original price by that decimal
699 x 0.3 = 209.7
add that number to the original price to get the total cost
699 + 209.70 = 908.70
the total cost is $908.70

Dwayne is 4 years older than Sarah. In 7 years the sum of their ages will be 48 . How old is Dwayne now?

zalisa [80]

Answer: 37

Step-by-step explanation: If you start your math by taking 48 and subtracting 7 you will get 41, this question says it the sum of both ages will be 48 in 7 years so subtract those to get 48. After, you can subtract 4 from 41 since that is just the sum of both ages, you take 41 and minus 4, your answer is 37 (sorry if its wrong but I think its most likely going to be correct)

the proper angle for a ladder is about 75 degrees. from the ground. suppose you have a 9 foot ladder. how far from the house sho

icang [17]

ANSWER:

2.33 foot

STEP-BY-STEP EXPLANATION:

We can calculate the distance from the staircase to the wall, by means of the trigonometric cosine ratio, which is the following:

$\begin{gathered} \cos \theta=\frac{\text{ adjacent}}{\text{ hypotenuse}} \\ \theta=75\text{\degree} \\ \text{ hypotenuse = 9 foot} \\ \text{adjacent = x} \end{gathered}$

Replacing and solving for x:

$\begin{gathered} \cos 75=\frac{x}{9} \\ x=9\cdot\cos 75 \\ x=2.33 \end{gathered}$

The distance would be 2.33 foot
