Answer:
328 square inches
PLZ MARK AS BRAINLIEST
Step-by-step explanation:
Lateral Area of Pyramid:
L = 1/2P<em>l</em>
<em>l</em> = 15.9
P = 2(8.2) + 2(8.2) = 32.8
L = 1/2(32.8)(15.9) = 260.76
Surface Area:
SA = B + L
B = (8.2)(8.2) = 67.24
L = 1/2(32.8)(15.9) = 260.76
SA = 67.24 + 260.76 = 328
Answer:
Step-by-step explanation:
The distance between the vertex and the directrix is 4 units, that means that p = 4 in the equation
and h and k are the coordinates of the vertex. Filling in:
which simplifies to
choice C
Answer:
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal
R represents interest rate
T represents time in years
I = interest after t years
Considering the first account,
T = 1 year
P = $10000
R = 5%
I = (10000 × 5 × 1)/100 = $500
The total amount = 10000 + 500 = $10500
he moved the total amount to a new account earning 6% interest. Therefore,
P = 10500
R = 6%
T = 1
I = (10500 × 6 × 1)/100 = $630
The amount of money that Marty would have at the end of the second year is
630 + 10500 = $11130
Answer:
36.46 inches
Step-by-step explanation:
The tangent of the angle is the ratio of the height to the base length:
Tan = Opposite/Adjacent
tan(25°) = (17 in)/(base)
base = (17 in)/tan(25°) ≈ 36.46 in
The base of the ramp is about 36.46 inches long.
