Hi there!

Given:
$4m + \frac{23 + n}{p - 3} \\ m = 7 \\ n = 2 \\ p = 8$

In order to evaluate the expression with the given values of m, n and p, we must substitute then into the expression. Then we use the correct order of operations (PEMDAS) to calculate.

Let's substitute first!
$4(7) + \frac{(23 + 2)}{(8 - 3)}$

Now find the numerator and denominator of the fraction.
$4(7) + \frac{25}{5}$

Next up: multiplying
$28 + \frac{25}{5}$

Divide the fraction.
$28 + 5$

And finally add the integers.
$33$

Hence, the answer is 33.
~ Hope this helps you!

Answer:

Finding volume:

2^2 = 4

4 x 3.14 = 12.56

12.56 x 8(height) = 100.48

100.48 divided by 3 ( x 1/3 ) = around 33.49 in3 is your answer.

If the options dont give you 33.49 just go by 33.51 cubic meters.

A pattern of dots is shown above. How many dots would be in the 7th picture ?

pav-90 [236]

Each drawing they are just adding another row to the right so for the 7th picture, there would be 28 dots. Another explanation is that they are just adding the same number of dots for each number it is. For example, for the 5th image, they added 5 dots to the previous image and so on.

Triangle ABC is described below. Find all possible values for B, C, and c.

aliya0001 [1]

Answer:

c = 27.9

B = 62.13°

C = 89.90°

Step-by-step explanation:

We are given the following values:

A= 121.59°, a = 27.9 cm, b = 52.6 cm

a) Finding side c

We would use Pythagoras Theorem

c² = a² + b²

c = √(a² + b²)

c = √(27.9² + 52.6²)

c = 59.54cm

≈ Approximately = 59.5cm

b) Finding B

We would be using Cosine rule to find Angle B

Cos B = a² + b² - c²/2ab

B = arc cos ( a² + c² - b²/2ac)

B = arc cos( 27.9² + 59.5² - 52.6²/ 2 × 27.9 × 59.5)

B = 62.13268°

B = 62.13°

c) Finding C

We would be using Cosine rule to find Angle C

Cos C = a² + b² - c²/2ab

C = arc cos ( a² + b² - c²/2ab)

C = arc cos( 27.9² + 52.6² - 59.5²/ 2 × 27.9 × 52.6)

C = 89.9°
