Answer: 5 toy cars
Step-by-step explanation: Hi there.
First, add the number of cars that he had, the number of cars he bought, and the number of cars he received for his birthday: 13+22+21=56
Then subtract your answer (56) from the number of toy cars he gave away to Wayne and his sister: 56-46-5=5
Therefore, Darrel has 5 toy cars left.
Have a nice day! :)
OK. First we have to figure out names for all the numbers you mentioned.
The mysterious number . . . . . call it Q
One fifth of the number . . . . . 0.2 Q
Five times the number . . . . . . 5 Q
Seven times the number . . . . 7 Q
(One fifth plus five times the number) . . . 5.2 Q
(Seven times the number less 18) . . . . . . 7 Q - 18
You said that these last two things are equal,
so I can write . . . . . . . . . . . . . . . . . . 7 Q - 18 = 5.2 Q
Now, subtract 7Q from each side . . . -18 = -1.8 Q
Divide each side by -1.8 . . . . . . . . . . 10 = Q
Answer:
B
Step-by-step explanation:
First, count how many squares there are: 8 squares.
Now, count how many triangles there are: 6 triangles.
Ratio is simply the number of one thing divided by the number of the other. Here, since we want the ratio of squares to triangles, we have:
8 squares / 6 squares
We can simplify this to:
8 / 6 = 4 / 3
And finally, this can be written in the "ratio notation":
4 / 3 = 4 : 3
The answer is B.
Answer:
90 ft
Step-by-step explanation:
Times the length by the width of one side: 6 x 3= 18
Times 18 by 4 to get the surface area of the 4 rectangular sides: 18 x 4= 72
Times 3 by 3 to get the bottoms surface area: 9
Times 9 by 2 to get both the top and bottoms surface area: 18
Add 72+18 to get the total surface area: 90 ft
