Answer:
5.8 = sqrt(34)
Step-by-step explanation:
c^2 = a^2 + b^2
c = sqrt(3^2 + 5^2)
Find the average of all the tests on the first and second test. You find the average by adding up all the test scores and dividing it by the number of test scores you added. Then you can see if she did better than the overal average on each of the tests
Answer:1:10 (simplified from 4:40)
Step-by-step explanation:
4 pencils + 12 markers + 24 crayons = 40 total items
4 pencils : 40 items
1 pencil : 10 items
Lets assume the sides of the isosceles triangle are:
Side A: x
Side B: x
Base: x/2
x+x+x/2= 46.8cm
2x+x/2=46.8cm
4x+x=93.6
5x=93.6
x= 18.72
Side A: 18.72cm
Side B: 18.72cm
Base: 9.36cm
The base of the largest triangular flag Sara can make is 9.36cm.
2x+x/2= 46.8cm
When given 3 triangle sides, to determine if the triangle is acute, right or obtuse:
1) Square all 3 sides.
2) Sum the squares of the 2 shortest sides.
3) Compare this sum to the square of the 3rd side.
if sum > 3rd side² Acute Triangle
if sum = 3rd side² Right Triangle
<span>if sum < 3rd side² Obtuse Triangle
</span>
1) 144
<span>
<span>
<span>
1,225
</span>
</span>
</span>
1,369
144 + 1,225 = 1,369
Therefore, it is a right triangle.
