a salesperson receives a 2.5% commission on sales. what commission does the salesperson receive for $8000 in sales?
Gelneren [198K]
The sales person receives a $200 sales commission. To get the answer, you would convert the percentage to a decimal, in this case... 2.5%, would become 0.025. You would then multiply 0.025•8000 to get your answer of $200. Which means in total, the salesperson would receive $8200.

Y varies directly as x. y=50 when x=5 find y when x=11????
olasank [31]

Step-by-step explanation:

given

y is directly to x

to remove directly we use constant let constant be k

y=k x. (1)

let calculate value of k

as it is given

y=50 when x=5

so put in above equation (1)

50=k(5)

50/5=k

10=k

now let find y when x =11

in above equation put the value of x and k

y=10×11

y= 110

31,50 is 42% os what number
sergeinik [125]
\frac{31,50}{x}=\frac{42}{100}

The right fraction represents the percentage; 42 over 100 (100 is the total), or 0.42.
The left fraction is the part number over the whole number. The whole number is unknown, so we use 'x'.


\frac{31.50}{x} = \frac{42}{100}\\\\cross\ multiply\\\\31.50\times100=3150\\42\times x=42x\\\\3150=42x\\x=75
Your answer is 75.

In a right triangle, what is the 3rd angle measure if an angle is 25
melomori [17]

Answer:

65

Step-by-step explanation:

The sum of the angles in a triangle is 180. In a right triangle, there is one 90 degree angle. If the second angle is 25, and 90+25+the last angle must add up to 180, simple math can find the value of the last angle.

180-90-25=65
