Answer:
7 7/8
Step-by-step explanation:
There are several ways to get there.
2.25×3.5 = 7.875 = 7 7/8
(2 1/4)(3 1/2) = (9/4)(7/2) = 63/8 = 7 7/8
(2 1/4)(3.5) = 2(3.5) +(1/4)(3.5) = 7 + (2·3.5)/(2·4) = 7 +7/8 = 7 7/8
A typical graphing calculator will let you enter this problem directly, giving you a result either as a decimal, improper fraction, or a mixed number.
Answer:
b = 8
Step-by-step explanation:
Using Pythagorean Theorem, a
, we just plug in what we know.
We know that the hypotenuse, c, is 10 km. We also know that one of the other side lengths is 6 km, we can plug that into either a or b.
Now, our equation will be:
.
You could also use the equation:
.
Next, we'll just solve the equation.
,
b = 8
Good luck :D
Answer:
![DE=18.38](https://tex.z-dn.net/?f=DE%3D18.38)
Step-by-step explanation:
It is given that the length of triangle base is 26 that is BC=26.
A line, which is parallel to the base divides the triangle into two equal area parts.
Therefore, from the given information,
.
Now, since it is given that A line, which is parallel to the base divides the triangle into two equal area parts, thus
![\frac{ar ADE}{arABC}=\frac{1}{2}=\frac{(DE)^{2}}{(BC)^{2}}](https://tex.z-dn.net/?f=%5Cfrac%7Bar%20ADE%7D%7BarABC%7D%3D%5Cfrac%7B1%7D%7B2%7D%3D%5Cfrac%7B%28DE%29%5E%7B2%7D%7D%7B%28BC%29%5E%7B2%7D%7D)
