John made $40 commissions for $500 sales or 40/500. He wants $320 for an unknown amount of sales or 320/x.
40/500=320/x Cross multiply.
40x=160,000
Divide both sides by 40.
X=4,000
He needs his sales to be $4,000 to get $320 in commission.
H =8
6 times 6 is 36 and times 8 is 288.
So first of all you can find x and y because all triangles have interior angles that add up to 180 degrees.
X= 10 degrees
Y= 60 degrees
Looking at the options, we see that the first statement is true. And if the angles are not equal, the triangles are not able to be similar.
3. 30g coffee.. 48 oz coffee
xg coffee.. 96 oz coffee
x = 96*30/48 = 2*30/1 = 60 g coffee, pick B
4. 2 16/20 = 56/20 = 28/10 = 14/5 = 2.8 meters, pick H
