Joselyn is a manager of a window installing company. She ask two professional installers, Mark and Anna, in install all the windows in a large home. Mark can install all the windows in 16 hours. Anna can install all the windows in 9 hours. Joselyn wants to know how long it will take them to install all the windows in the home if they work together. Write an equation and solve for the time it will take Mark and Anna to install all the windows together. Explain each step.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%

step-by-step explanation:

step-by-step explanation:

classify each pair of angles as alternate interior, same-side interior, or corresponding angles.

option (a)

step-by-step explanation:

step 1:   take 2 number whose product equal to 25..

and sum of those two number are -10

step: 2 for example here if we take 5,5 are the number,,

5*5=25

and

5+5=10

but we need -10

so if we take   -5,-5

so -5*-5=25

and -5+(-5)=-10

s0

come the equation

replace -10x by these number

like -5x -5x+25

take common

x(x-5)-5(x-5)=0

(x-5)(x-5)=0
