Answer:
D. 104
Step-by-step explanation:
We know that xy and yz are supplementary to each other
That means they add up to 180
We can set up an equation with this information
(4x+32)+(2x+40)=180
6x+72=180
6x=108
x=18
Now that we know what x is, we can plug it into 4x+32 to find degree of xy
4(18)+32
72+32
D. 104
Answer:
Step-by-step explanation:
Rule: the largest angle is ALWAYS opposite the longest side, and the converse is also true: the longest side is always opposite the largest angle. So the largest side is E which is B
Answer:
$660
Step-by-step explanation:
So first we convert the percentage (12%) into decimal point: 12%/100+0.12
To find the discount you're going to get, multiply the price of the computer by your new decimal value: 750×0.12= $90
$90 will be the discount you're getting. Now subtract it from the computer price to get the discounted price: 750-90= $660
The discounted price of the computer would be $660
we know it takes 20lbs of Olive to make 3 liters of oil, we also know that the orchard for a whole year gets 3000 lbs, how much oil is there in those 3000 lbs for the year?
Answer:
0% of the racers finished in 28 minutes or less
Step-by-step explanation:
There is the need to understand the meaning of the standard deviation in this question.
The <em>standard deviation expresses by how much the finishing time differed from the mean/average time</em>. So, it tells us that the time range for all of the racers can be written as Mean ± Standard Deviation = 32 ± 2 minutes = (32 - 2) to (32 + 2) = 30 to 34 minutes.
So, all of the racers finished in 30 minutes or more, and no one finished in less than thirty minutes.
The questions asked to know o those who finished in 28 minutes or less, and that does not exist in this given data, so 0% of the racers finished in 28 minutes or less
