Answer:
56/100 or 0.56
Step-by-step explanation:
you first need the dinominators to be the same so to figure that at you can do 100 divided by 10 which is 10. so to make the doniomators even you need to multipy the 2/10 by 10. so 2x10=20 and 10x10=100 so that makes the fraction 20/100. now you have 20/100 + 36/100 =? which makes it a lot easier. so now all you do is add ONLY THE NUMERATOR so you do 20+36 which is 56 and you keep the 100 and that 56/100.
To make it into a decimal, this one is easy because the denominater is 100 so you just take 56.0 and move the decimal two place values so its 0.56. :)
Answer:
Area= 840
Step-by-step explanation:
Area= (20x13)x2+(10x12x1/2)x2+10x20
=520+120+200
=840
- Area=Two area of the triangle [13x20] + Two area of the rectangle + Under area (rectangle)- [10x20]
Answer:
y < 2
Step-by-step explanation:
So let's say the number on the line is "y".
And the circle is not filled in so our number can't equal 2 or less. It has to be over 2, therefore its. y < 2
hope it helps!! :)
Answer:
65 tickets for children
Step-by-step explanation:
In this case we can solve it by means of a 2x2 system of equations, like this:
Let x be the ticketsr of children
let y be the tickets of adults
Thus:
5.3 * x + 9.4 * y = 852.1
x + y = 119 => x = 119 - y
replacing, we are left with:
5.3 * (119 - y) + 9.4 * y = 852.1
630.7 - 5.3 * y + 9.4 * y = 852.1
9.4 * y - 5.3 * y = 852.1 - 630.7
4.1 * y = 221.4
y = 221.4 / 4.1
y = 54
Now to calculate x:
x = 119 - 54
x = 65
Which means that there are 65 tickets for children and 54 tickets for adults.
