Answer:
84.5
Step-by-step explanation:
Use trig functions to find x. Trig functions are special relationships which exits between the sides of right triangles. Since you need to find x the hypotenuse and you have the adjacent side to 77 degree angle use cosine.
Cos 77 = 19/x
0.22495 = 19/x
19/0.22495 = x
84.5 = x
Answer:
140
Step-by-step explanation:
times 10 and 14 together
Answer:
80, 70 and 87
Step-by-step explanation:
-Range is mathematically defined as the difference between the largest and smallest data point in a data set.
-Given the mean=79, median=80 and the range is 17.
#let a be the largest score and b be the smallest score:
The sum of the 3 scores is equivalent to the 237.
#we subtract the given median and equate using range to solve for a and b;
Hence, the test scores are 80, 70 and 87
-5 + 6d + 3 = 34
-2+6d=34
Add 2 to both sides
6d=36
Divide both sides by 6
6d/6=36/6
d=6
Check:
-5 + 6d + 3 = 34
Substitute d=6 into the equation
-5+6(6)+3=34
-5+36+3=34
31+3=34
34=34
Hope this helps! :)
Find out what number $350 is 8% of, since he makes 8% commission on sales. In the percent formula: a = pb
a is the part, p is the percent (as a decimal), b is the base
350 is 8% of what number? 350 = 0.08b {substituted given values into percent formula and changed 8% to a decimal}
b = $4,375 {divided each side by 0.08}
He needs to make at least $4375 worth of sales.
