Answer 1

Answer:

Since the squarebase has side 6 cm and triangular side has height 10 cm, the total surface area of square pyramid is 156 cm²

What is the Total surface area of a square pyramid?

A square pyramid has a square base and four triangular sides, its surface area, A = area of square base + 4 × Area of triangular side.

Area of square base

Area of square with side, L is A = L²

Area of triangularbase

Area of triangle with height and base, L which is the length of the square base is A' = 1/2Lh

Thus, total surface area of square pyramid ,

A" = L² + 4 × 1/2Lh

= L² + 2Lh

Given that the length of the square base is 6 cm and the height of the triangular side is 10 cm.

Now substituting the values of the variables intot he equation, we have

A" = L² + 2Lh

A" = (6 cm)² + 2 × 6 cm × 10 cm

A" = 36 cm² + 120 cm²

A" = 156 cm²

So, the total surface area of square pyramid is 156 cm²

Your bank balance is $102.35 and you've just made purchases for $20, $33.33, and $52.80. You then make deposits of $25 and $24.75. What's your new balance?

Answers

Answer:

The new balance is $45.97 .

Step-by-step explanation:

As given

Your bank balance is $102.35 and you've just made purchases for $20, $33.33, and $52.80.

Bank balance after the purchase = $102.35 - $20 -$33.33 - $52.80

= $102.35 - $ 106.13

= - $3.78

As given

You then make deposits of $25 and $24.75.

Total deposit money = $25 + $24.75

= $49.75

Thus

New balance = Bank balance after the purchase + Total deposit money

= - $3.78 + $49.75

= $ 45.97

Therefore the new balance is $45.97 .

$102.35 - $20 = $82.35
$82.35 - $33.33 = $49.02
$49.02 - $52.80 = $-3.78
$-3.78 + $25 = $21.22
$21.22 + $24.74 = $45.97
so $45.97 is your answer

The model y = 500(1.035)^x, indicates the value of an investment, where x is the number of whole years. What's the growth factor (the ratio from one year to the next)?

Answers

Given:
model y = 500(1.035)^x is the value of the an investment after x years.

the growth factor of this model is 1.035

Let us assume that x = 3 and x = 2

y = 500(1.035)² = 500 (1.07) = 535
y = 500(1.035)³ = 500 (1.11) = 555

growth factor = 555 / 535 = 1.037 or 1.035

Answer:

7-x

Step-by-step explanation:

49 - x^2 is a perfect square so

it factors to :(7+x)(7-x)

since there is a negative in 49 - x^2, it would make sense that the answer would be a negative to get that negative answer in the first place (negative times a positive equals a negative)
