We use x to represent the price of the cheapest hat. Since the more expensive hat is twice the price of the cheaper one, we use 2x to represent it. Therefore x + 2x, or 3x, equals $75.12. Divide 75.12 by 3 to find x, which is 25.04. The more expensive hat is 2x, so we must multiply 25.04 by 2 to find the price of the more expensive hat. Therefore, the cost is $50.08.
Answer:
let the breadth of room be 'x'm
so the lenghth of room is 'x+8'm
Given
Area of room=48m²
i.e length ×breadth =48m²
or,(x+8)x=48
or,x²+8x-48=0
or,x²+12x-4x-48=0
or,x(x+12)-4(x+12)=0
or,(x+12)(x-4)=0
Either x+12=0
or,x=-12(which is not possible)
Or,x-4=0
or,x=4
Thus,breadth is 4m.
length=x+8=4+8=12m
The dimensions of room are 8m and 12m respectively.
If each is similar, then 6 times (5) = 30
therefore 8 times (5) = 6X - 8
40 = 6X - 8
add 8 to both sides 48 = 6X
divide by 6 8 = X
Answer:
9 , 4 , 1 , 2
Step-by-step explanation:
Given that Hiro picked up 4 digit cards and the cards will make Multiple of 10
The numbers on the digit cards that will most likely make Multiple of 10 are :
9 , 4 , 1 , 2
Answers:
- 10 people absent
- 15 people working in the field only
- See the below image for the venn diagram
=======================================================
Explanation:
- 35 people are working in both places.
- 50 work in the field or both, so 50-35 = 15 people work solely in the field.
- 65 work in the office or both, so 65-35 = 30 people work solely in the office
So far that accounts for 15+30+35 = 80 people who work in the field, the office, or both.
The remaining 90-80 = 10 people are absent.
The venn diagram is below.
