Answer:
STEP BY STEP EXPLANATION
To make a perfect square we should add
First set up the ratio 2/5 = 10/x where <em>x</em> is the number of girls.
Now, we can use cross-products to find the missing value.
So we have (2)(x) = (5)(10).
Simplifying, we have 2x = 50.
Dividing both sides by 2, we find that x = 25.
So there are 25 girls in the class if there are 10 boys.
The correct answer should be A.
First consider that 2357/1180 is around 2. So the first part must have the answer of times 2. Then decide how many zeroes must be added. By simple math if you do 118,000,000,000 * 20 (which is ) then you get 2,360,000,000,000. which is roughly the correct number.
Answer:
17/3
Step-by-step explanation:
convert the element to a fraction, then since the demonators are equal, combine the fractions.
Surface area : The area of the surface of the figure.
We will find the area of each separate figure, then add them al up:
Triangle: (3*4) / 2 = 6
For 2 triangles the surface area will be 12.
Square: 3*3 = 9
Rectangle One: 4*3= 12
Rectangle two: 5 * 3 = 15
Now we add them all up:
12 + 9 +12 + 15 = 48
So the surface area is 48 cm^2
