Answer:
3 2
/7
Step-by-step explanation:
Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.
Answer:
area: 72 perimeter: 36
Step-by-step explanation:
area of big rectangle, 10x6=60
height of triangle:4 multiplied by 3 (6/2=3) =12 12+60=72
length of sides added together: 10+10+6+5+5=36
Answer:
1. 5 cm
2. 7.07 cm
Step-by-step explanation:
According to your provided information, the area of a square is A = s^2. They also tell you that the area of the square in the picture is 25cm^2. That means that, to find the length of any side (s), you just need to plug 25 in as the area. So
25 = s^2 ... Take the square root of both sides to isolate s.
s = ±5 ... But since we're talking about length, we only take the value positive five. (Length can't be a negative value.)
Now we have the length of any side as 5 cm, and they want us to find the length of the diagonal. We can use the Pythagorean theorem, a^2 + b^2 = c^2, where c will be the diagonal we want. We can do this because we know that ANY side of this square is s = 5, so if we plug that into a^2 + b^2 = c^2, we get
5^2 + 5^2 = c^2 ... 5 times 5 is 25
25 + 25 = c^2 ... Add
50 = c^2 ... Take the square root of both sides
c = √50 ... Use a calculator
c ≈ 7.07
