Answer : C

To solve any question asking if a triangle is acute, obtuse, or right based on side lengths you have to follow this method.
Square all sides of the triangle. Then add the two shortest sides together. If the two shortest sides are bigger than the largest side then the triangle is acute. If the sum is equal then the triangle is a right triangle. And if the sum is less than the longest side then it’s obtuse. Hope this helps :).

The base of a triangle is 8 1 3 meters and the height of the triangle is the fourth root of 16 meters meters. What is the area o

just olya [345]

Answer:

The area of triangle is $8 \frac{1}{3}\ m^{2}$

Step-by-step explanation:

we know that

The area of a triangle is equal to

A=(1/2)bh

we have

b=8 1/3 m

convert to an improper fraction

8 1/3 m=(8*3+1)/3=25/3 m

The fourth root of 16 is equal to 2

$\sqrt[4]{16}=(2^{4})^{1/4}=2$

h=2 m

substitute

$A=(1/2)(25/3)2=25/3\ m^{2}$

convert to mixed number

$25/3=(24/3)+(1/3)=8+1/3=8 \frac{1}{3}\ m^{2}$

Please please help I really need it today please show work

Answer:

x=9.

perimeter=68

area=168

Step-by-step explanation:

First find the side that has a exact number which would be the bottom 28cm then look at the opposite side (2x+10) in order to find x subtract 10 from 28 which gives you 18, now 2x means x multiplied by 2 so what multiplied by 2 = 18? 9 meaning x=9. Now you are going to want to plug 9 in to your short side (x-3) once you plug it in it should look like this 9-3 and 9-3=6 meaning the short side is 6cm. In order for you to find the perimeter you have to add the sides together so 28+28+6+6 wich =68 and in order for you to find the area you have to multiply the length and the width so 28x6 which is 168.

hope that helped :)

How many real zeros does the function graph below have?

Nostrana [21]

Answer:

Step-by-step explanation:

If the graph crosses the x-axis and appears almost linear at the intercept, it is a single zero. If the graph touches the x-axis and bounces off of the axis, it is a zero with even multiplicity. If the graph crosses the x-axis at a zero, it is a zero with odd multiplicity.

You have a 2/6 chance of rolling a number greater than 4 or less than 3 which reduces to 1/3
2/6 = 1/3
