Answer:
Part A: C, Part B: A, E, i, K 160 cm, A: 21, Use PEMDAS and you get 13 5/7.
Step-by-step explanation:
1.6 x 100 meters = 160 centimeters
3 x 7/1 = 21/1 = 21
Cosine = adjacent / hypotenuse
cos (49)= x/27
27 * cos(49) = x
27 * 0.656 = x
x = 17.7
Answer:
.797
Step-by-step explanation:
If your talking about a decimal number, you would say the <u>thousandth</u>. I know, weird, but don't blame me.
To round up, any number above 5 rounds up to the next value place, and any number below 5 rounds down to the last value place.
Ex: 1.3483838383
Since 8 is greater than 5, we could get rid of all the 83s and just round up to 1.35.
So the thousandths place in a decimal would be 0.79<u>6</u>66357977, so we just ask if the next number after the thousandths place is greater than 5. The place number after .796 is 6, so since it is greater than 5, we would round up to .797.
Our answer is .797.
Hope this helps!
Set up an equation to solve.
$8.50x (since it is the rate of change) + $12 (flat fee) = total money earned (or y). In this case, we have the total, amount, and are looking for x. Plug $139.50 into the equation.
$8.50x + $12 = $139.50
Now, solve for x.
$8.50x + $12-12 = $139.50-12 > <em>$8.50x = $127.5</em>
$8.50/8.50x = $127.5/8.50 > <em>x = 15</em>
So, the correct answer is <u>D. Olivia babysat for 15 hours.</u>
