Answer:

h = 3

Step-by-step explanation:

Looking at the given image, the height(h) divides the side length of 8 into two equal parts as we see that the height is perpendicular to the side length of 8 m.

Thus, looking at the half triangle of the face where the h is indicated, we can use pythagoras theorem to find h where the hypotenuse is 5 as shown in the diagram since each vertical cross section is an Isosceles triangle. Thus,

h² + (8/2)² = 5²

h² + 4² = 25

h² + 16 = 25

h² = 25 - 16

h² = 9

h = √9

h = 3

One leg of a triangle is 7 inches. another leg measures 5 inches. if the perimeter of the triangle is 19 inches, find the length
Setler79 [48]

SOLUTION

A triangle has three sides. The sides of this triangle are 7 inches, 5inches and the unknown side.

Let the unknown side be x inches.

Perimeter is distance around a plane shape.

The perimeter of this triangle is 19,

\begin{gathered} \text{  That is the perimeter  1}9=7+5+x \\ 19\text{ = 12 }+x \\ x\text{ = 19 - 12 } \\ x\text{ = 7 inches } \end{gathered}

Therefore, the other side is 7 inches

The Freeman family is barbecuing veggie burgers, corn cobs, and mushroom caps in their local park. If 3/8 of the items barbecued
algol [13]

Answer:

7/24

Step-by-step explanation:

Let

total items barbequed = 1

Veggie burgers = 3/8

Corn cobs =1/3

Mushroom caps = x

Veggie burgers + corn cobs + x = 1

3/8 + 1/3 + x = 1

9+8 /24 + x = 1

17/24 + x = 1

x= 1 - 17/24

=24-17 /24

= 7/24

x = 7/24

Fraction of barbequed items that are mushroom's is 7/24
