Answer:

B. 14

Step-by-step explanation:

Area of a triangle: $\frac{1}{2} bh$

Base of this triangle: 7-3= 4 (look at image below)

Height of this triangle: 5+2= 7 (look at image below)

$A=\frac{1}{2} (4)(7)\\A=\frac{1}{2} (28)\\A=14$

Hope this helps.

Answer:

The linear equation is:

$B(d) = 9500 - 165d$

Step-by-step explanation:

Linear function:

A linear function has the following format:

$y = mx + b$

In which m is the slope(how much y changes when x changes by 1) and b is the y-intercept(value of y when x = 0).

A company has an inventory of books that is decreasing at a constant rate. Write a linear equation for B in terms of d.

This means that the situation is modeled by a linear function in the following format:

$B(d) = B(0) + md$

After selling the book for 4 days, they have 8.840 books in stock and after selling it for 10 days they have 7,850 books in stock.

This means that B(4) = 8840, B(10) = 7850

Finding the slope:

The slope, having two points, is given by the change in the output(in this case B) divided by the change in the input(in this case d).

We have the points

(4,8840) -> When d = 4, B = 8840

(10,7850) -> When d = 10, B = 7850

Change in B: 7850 - 8840 = -990

Change in d: 10 - 4 = 6

Slope: $m = \frac{-990}{6} = -165$

$B(d) = B(0) - 165d$

(10,7850) -> When d = 10, B = 7850

We use this to find B(0). So

$B(d) = B(0) - 165d$

$7850 = B(0) - 165*10$

$B(0) = 9500$

The linear equation is:

$B(d) = 9500 - 165d$

The least natural number that is divisible by three different primes is

pickupchik [31]

Natural number is any positive whole number. In order to solve this question there are two possible ways:

1) We start by writting down natural numbers one by one. Then we check for it's divisors that are prime numbers. We continue doing this until we find the solution. This approach could take quite some time to complete but it will eventually give the correct answer.

2) We need to find natural number that is divisible by three primes. And it needs to be smallest possible. This means that the product of these numbers is our solution.
We can not take any three random primes as they will not give us the requested solution. 7* 11 * 31 = 2387
We need to take three lowest primes. Those are 2, 3 and 5. 1 is not considered to be a prime.
2 * 3 * 5 = 30
So our solution is 30. All lower numbers do not have three primes as divisors.
