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 = 
Area of one Triangular Face 
Therefore:
Lateral Surface Area 
Therefore, Talia is correct.
Answer:
MAKE MY ANSWER BRILLINEST PLEASE:)
Step-by-step explanation:
LET:
j = the points that Jessica scored
t = the points that Tina scored
Jessica scored 147 more points than Tina:
j = t + 1497
Together, Bradley and Harner scored 1601 points:
j + t = 1601
by solving the system of equations:
j = t + 147
j + t = 1601
we find
j = 856 points
t = 707 points
Jessica Bradley scored 856 point.
Tina Harner scored 707 points.
I believe the answer is 16
15% of 1560 is 234. 234/0.15=1560 and 1560 x 0.15=234, therefore the answer is 1560.
