Answer:
(B) Talia is correct. The lateral area can be found by approximating one large triangle, which can be found using the expression 4 (one-half (8) (6.9))
Step-by-step explanation:
Base of the Pyramid = 8 Inches
Height of the Triangular Face = 6.9 Inches
In any solid shape, the Lateral surface area is the sum of all sides except its top and bottom bases.
Since the four triangles are congruent:
Lateral Surface Area = 4 X Area of One Triangle
Area of a Triangle = ![\frac{1}{2}$ X Base X Height](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%24%20X%20Base%20X%20Height)
Area of one Triangular Face ![= \dfrac{1}{2}(8)(6.9)](https://tex.z-dn.net/?f=%3D%20%5Cdfrac%7B1%7D%7B2%7D%288%29%286.9%29)
Therefore:
Lateral Surface Area ![= 4\left(\dfrac{1}{2}(8)(6.9)\right)](https://tex.z-dn.net/?f=%3D%204%5Cleft%28%5Cdfrac%7B1%7D%7B2%7D%288%29%286.9%29%5Cright%29)
Therefore, Talia is correct.

Answer:
I don't understand the array of numbers as written in the question.
Step-by-step explanation:
See attached image
Step-by-step explanation:
x = mass of apples
y = mass of strawberries
z = mass of the box
x = 3y
x + z = 16240
y + z = 6350
let's subtract the second from the first equation
x + z = 16240
- y + z = 6350
-----------------------
x - y + 0 = 9890
using the first identity in that result gives us
3y - y = 9890
2y = 9890
y = 4,945 g
x = 3y = 3×4945 = 14,835 g = the mass of the apples
Answer:
DOMAIN: 2, 5, 7
RANGE: 2.3, 2.3, 15
Step-by-step explanation:
Domain is always the first value of the set, and range is always the second value of the set. Hope it makes sense, and that it helped.
Have a good day! goodluck.
