Evaluate the expression when a = 4, b = 15, and c = 16.
a+c

will give brainliest

Answers

Answer 1

Answer:

20

Step-by-step explanation:

This is the information we know :

A. a = 4

B. b = 15

C. c = 16

a + c

The a and c represent variables that must be substituted by their value, since we know their initial value, we substitute :

a + c when a = 4 and c = 16

4 + 16

20

Answer 2
The answer is 20 because a=4 and c=16 then 4+16=20

Jamal's NMI= $ _____

Answers

Answer:

:)

Step-by-step explanation:

Since his wage is 8.75*63=551.25, we can add up the percentages to get 10+6.2+1.45+4+0.1=21.75%. To get 21.75%, we can move the decimal 2 to the left to get 0.2175. Multiply that by 551.25 to get around 119.9 dollars. If you'd like to calculate the individual taxes, you can apply a similar process to figure that out

6) Write a system of linear inequalities that is given by the following graph.

Answers

Answer:

The system of inequalities are x - y < 1 and y < - 2 The horizontal line shown in the graph has equation y = - 2 {As it is parallel to x-axis} Now, this line is dotted and the lower portion of the graph is shaded. So, the inequality will be y < - 2 ......... (1) Again, another line is there in the graph which passes through the points (1,0) and (0,-1)So, its equation will be

⇒ y + 1 = x ⇒ x - y = 1 Now, the origin (0,0) is within shaded zone of the inequality and putting x = 0 and y = 0, we get 0 - 0 < 1 So, the equation of the inequality is x - y < 1 {As the line is dotted} Therefore, the system of inequalities are x - y < 1 and y < - 2 (Answer)

x=[tex]\sqrt{15^{2} -12^{2} }[/tex]

x=9 in.

The Pythagorean theorem is a^2+b^2=c^2

So if we plug in a as 12 and c as 15 we get 144+b^2=225 we then solve to get b^2=81 and so b=9.

In your case, b=x, therefore x=9.

A box contains 6 red marbles, 4 green marbles, 3 blue marbles, and 2 yellow marbles. If Greg chooses one marble at random 300 times, how many times would he expect the marble to be blue?

Answers

Answer:

[tex]60[/tex] times

Step-by-step explanation:

There are [tex]6+4+3+2=15[/tex] marbles in total. Out of those, [tex]3[/tex] are blue, so the probability of pulling a blue marble is [tex]\frac{3}{15}=\frac{1}{5}[/tex]. However, this is only the probability of pulling a blue marble when [tex]1[/tex] marble is pulled at random. Therefore, we can expect a blue marble to be pulled [tex]\frac{1}{5}*300=60[/tex] times if [tex]1[/tex] marble is pulled [tex]300[/tex] times at random. Hope this helps!

all of the triangles have the same area since this is a square pyramid
area of triangle = (base X height)/2
so it would be (8 X 9)/2 = 36

for the square, the area is length X width
so it would be 8 X 8 = 64

add all the areas
