Answer:350
Step-by-step explanation:700 divided by 2
Answer:
the answer is D: 294 sq. cm
Step-by-step explanation:
first you want to split the net into 4 triangles and 1 rectangle
a = 12 cm
b = 6 cm
d = 13 cm
calculate the surface area of the pyramid...
1st find the area of the rectangle base
Rectangle base area
b x a = (6 cm) (12 cm)
= 72 sq. cm
next find the area of the triangle on the left
Left triangle
1/2(b)(d) = 1/2 (6 cm)(13 cm)
= 1/2 (78 sq cm)
= 39 sq. cm
Since all the triangles are congruent (same), you will need to multiply by 2 to get the combined area of the triangle on the left and on the right.
Area of left & right triangles
= 2 (39 sq. cm)
= 78 sq. cm
Find the area of the triangle on the bottom
Bottom triangle area = 1/2 (a)(a)
= 1/2 (12 cm) (12 cm)
= 1/2 (144 sq. cm)
Since the bottom of the triangle is congruent to the top triangle, multiply that by 2 to get a combined area of the triangle on the bottom and top
Area of top & bottom triangles
2 (72 sq. cm) = 144 sq. cm
Finally...add the area of the 4 triangles to the area of the rectangular base
72 + 78 + 144 = 294 sq. cm
at least 8
The answer would be A
Both congruent sides are pairs
Slope of the function is ,Y-intercept .
The function is with initial value,Jordan puts each week andthe amount saved by Jordan after week .
To understand the slope and y-intercept lets assign as number of weeks and as the money saved by Jordan.
Jordan is already having a sum of inside the money bank so in week the amount is can be written as in coordinate form.
SImilarly
We have and
Part A:
The function is
From point-slope form,we have slope (m)
and ,plugging the values of the points.
Y-intercept of this function is the constant term or the money of that is already inside the money bank.
We can also calculate y-intercept by arranging the function as choosing any coordinate and here is the y-intercept.
The result will be same.
Part B:
The equation <u></u> can represent the function described.
And the initial value is the <u>y-intercept </u>
Jordan puts<u> </u>in his bank each week.
After week the amount saved by Jordan ,here ,as the x-variable is the number of weeks.
Plugging the value of in where so the equation becomes
So basically the function is and the amount saved by Jordan after week .
