Answer:
xx(0.65) + xx(0.08)
Step-by-step explanation:
First step is to find the discounted price. Finding 35% less than the original xx is the same as finding 65% of it, so we multiply by 0.65. Once this is completed we need to find 8% more than that. So we add 8% of xx, which is the same as multiplying by 0.08. Hope this helps :)
Step-by-step explanation:
tan 60 = 21 ÷ y
1.73 = 21 ÷ y
y = 21 ÷ 1.73
y = 12.14
tan 30 = x÷ 12
0.6 x 12 = x
x = 7.2
Total number of people is 55
<u>Step-by-step explanation:</u>
Step 1:
Given ratio between boys and girls is 4:1. Let number of girls be x, so number of boys = 33 + x
⇒ 4x + x = x + 33 + x
⇒ 5x = 33 + 2x
⇒ 3x = 33
⇒ x = 11
Step 2:
Find total number of people.
33 + 2x = 33 + 22 = 55
L X W = A. So, if the top of the table is 4 ft, you need to find the sq. route of 4. (HINT: the sq. route can be doubled to equal the area.
