Evaluate the expression below when a = 5 and b = 2: a (10b - 2a).
Answer:
50Step-by-step explanation:
First, substitute the 2 given values into the expression.
a ( 10b - 2a )
5 ( 10(2) - 2(5) )
Simplify to the lowest terms possible, without distributing.
5(20-10)
Distribute 5 into each term.
100-50 or 20(5)-10(5)
=50

There are 199 green marbles and 199 red marbles in a bag. How many marbles must be chosen to be certain we have the following. Four red or three green?
Answer:
203 for four red and 202 for three green.
Step-by-step explanation:
Consider the worst possible choice. If you want four red then imagine the worst possible case. That'd be picking all 199 marbles before any red, and after you pick all 199 green marbles you still need four red, and 199+4=203. For green, do the same thing and you get 199+3=202
There are 203 for four red and 202 for three green.
Given that,
There are 199 green marbles and 199 red marbles in a bag.Based on the above information, the calculation is as follows:
Since there is 4 red or three green.
So,
We can solve like
= 199 + 3
= 202
And,
= 199 + 4
= 203
Therefore we can conclude that there are 203 for four red and 202 for three green.

The value of the expression is 55/3.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
84 ÷ 42 x 6 + 18
Using the PEMDAS rule.
84 ÷ 252 + 18
84/252 + 18
1/3 + 18
(1 + 54)/3
= 55/3
Thus,
The value of the expression is 55/3.

can someone please help me!! this assignment is due at 11:59 I need this done
Answer:
Step-by-step explanation:
Tan (theta) = opposite / adjacent
theta = 60 degrees
opposite = 15
adjacent = opposite / Tan(theta)
adjacent = 15 / tan(60)
tan(60) = sqrt(3)
sqrt(3) = 1.732
adjacent = 15 /1.732
answer: adjacent = 8.6603

I need help surface area
Answer:
[tex]\huge\boxed{318yd^2}[/tex]
Step-by-step explanation:
The object shown in the diagram is a triangular prism, which contains two triangular sides and three rectangular sides.
The area of a triangle is simply [tex]\frac{bh}{2}[/tex].
Because the triangles are both the same, you may multiply the equation by 2 to get simply bh, or 9 * 6, or 54.
Then, simply solve for the areas of each rectangle:
r1 = 11 * 7 = 77
r2 = 11 * 8 = 88
r3 = 11 * 9 = 99.
Then, simply add all the values to get:
99 + 88 + 77 + 54
318.

Find the average rate of change between x=2 and x=4 for the function. F(x)=3x^3-1
Answer:
84Step-by-step explanation:
Average rate of change between x = 2 and x = 4 is:
