damaskus [11]3 years ago
5 0

Answer:

The answer is B

Step-by-step explanation:

S.A of pyramid = base area × 4(area of triangle)

base area = (24×24)in

= 576in²

area of triangle = (1/2)×24×12

= 144in²

S.A = 576 + 4(144)

= 1152in²

Luisa and Connor had $360 altogether . After Connor gave Luisa 2/5 of his money, she had the same amount of money has he did. Ho
Liula [17]

Answer:

$300

Step-by-step explanation:

Let's say that L is the amount of money Luisa had in the beginning, and C is the amount of money Connor had in the beginning.

C + L = 360

C - 2/5 C = L + 2/5 C

Simplifying the second equation:

3/5 C = L + 2/5 C

1/5 C = L

Substituting into the first equation:

C + 1/5 C = 360

6/5 C = 360

C = 300

Connor originally had $300, and Luisa $60.  Connor gave Luisa $120, and they both had $180.

A clock has a diameter of 16 inches. Which measurement is closest to the area of the clock in square inches? 804.25 in2 50.27 in
meriva

Answer:

200.96 in2

Step-by-step explanation:

Area of a circle = nr²

n = 3.14

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

diameter = 2r

radius = 16 inches / 2 = 8 in

Area = 3.14 x 8² =  200.96 in²

Differentiate Functions of Other Bases In Exercise, find the derivative of the function.
densk [106]

Answer:

The derivative of the function is:

g'(x) = \frac{1}{1.6094x}

Step-by-step explanation:

If we have a function in the following format:

g(x) = \log_{a}{f(x)}

This function has the following derivative

g'(x) = \frac{f'(x)}{f(x)*\ln{a}}

In this problem, we have that:

g(x) = \log_{5}{x}

So f(x) = x, f'(x) = 1, a = 5

The derivative is

g'(x) = \frac{f'(x)}{f(x)*\ln{a}}

g'(x) = \frac{1}{x*\ln{5}}

g'(x) = \frac{1}{1.6094x}
