30 dolls.
You can get this by multiplying the number in 20% by 5, which would get you to 100% and 30.
Answer:
19 degrees.
Step-by-step explanation:
First solve the angles in the top triangle:
FHG = 180 - 135 = 45 (angles on a straight line = 180)
FGH = 180 - 105 = 75 (angles on a straight line = 180)
Using these we get HFG = 180 - 45 - 75 = 60 (angles in a triangle = 180)
Then because HFG is directly opposite DFC on the crossed lines, we know they are equal: DFC = 60
FDC = 180 - 119 = 61 (anges on a straight line = 180)
Now if we label ABC (the target angle) as x then we known ACB = 180 - 40 - x.
With this we know FCD = 180 - ACB = 180 - (180 - 40 - x) = 40 + x (angles on a straight line).
Finally using the FDC triangle we have 40 + x + 60 + 61 = 180 so x = 180 - 40 - 60 - 61 = 19 degrees.
Answer:
Correct option is c.
Step-by-step explanation:
The information provided is:
- It costs $83 a day to rent a car plus a required fee for insurance.
- The total cost for renting the car for 7 days is $621.
Then the cost of renting the car for 7 days will be, (83 × 7).
Let <em>b</em> denote the required fee for insurance.
Then the equation representing the total cost of renting is:
621 = 83(7) + b
Compute the value of <em>b</em> as follows:
621 = 83(7) + b
621 = 581 + b
b = 40
So, the correct option is c.
Answer: 81 m^2
Step-by-Step Explanation:
No. Of Square Wallpapers = 9
Side Length (s) = 3 m
Area of 1 Square Wallpaper = s * s
Therefore,
= s * s
= 3 * 3
=> 9
Area of 1 Square Wallpaper = 9 m^2
Area of Wall = Area of 9 Wallpapers
= 9 * 9
=> 81
Area of Wall = 81 m^2
