Steve earns $1575 a month.
Below is his monthly budget:
.3/5 of his budget is for rent and utilities
.1/3 of his income is for food and other expenses

How much money will Steve put into his savings account each month?

Answers

Match the graph shown with the following equation
Answer a and b please

Answers

Answer:

a) D b)B

Step-by-step explanation:

a) the graph is of negative slope as it slants downwards hence slop/gradient is negative. y intercept is positive so only option d is right

b) sub each option point into 3y = 2x - 1 if they equate to be the same, it is correct.

3(2) = 2(6) - 1

6 = 11 (not equal)

3(1) = 2(2) - 1

3 = 3 (equal) this is the answer

of course you can sub in the rest to confirm but I'm lazy so yeah I'll stop here

A hemispherical bowl is made of brass has an inner diameter 35 cm. What is the inner surface area? URGENT

Answers

Answer:

The inner surface area is: 1923.25 cm²

Step-by-step explanation:

A hemispherical bowl is made of brass has an inner diameter of 35 cm.

i.e. d = 35 cm

As the radius is basically half of the diameter.

r = d/2

  = 35/2

   = 17.5 cm

The inner surface area of a hemispherical bowl = 2πr²

= 2(3.14)(17.5)²

=1923.25 cm²

Therefore, the inner surface area is: 1923.25 cm²
