The measures of the numbered angles are as follows:
3.
m∠1 139°m∠2 = 41°m∠3 = 139° m∠4 = 139° m∠5 = 41°m∠6 = 139°m∠7 = 41°4.
m∠1 = 117° m∠2 = 63°m∠3 = 117°m∠4 = 63° m∠5 = 117° m∠6 = 63° m∠7 = 63° How to find measures of angles?When parallel lines are cut by a transversal line, angle relationships are formed such as alternate angles, corresponding angles, linear angles, vertically opposite angles etc.
Therefore, line a and b are parallel to each other. The transversal line t cut the parallel lines.
Hence,
3.
m∠1 = 180 - 41 = 139° (angles on a straight line)
m∠2 = 41° (vertically opposite angles)
Vertically opposite angles are congruent.
m∠3 = 139° (vertically opposite angles)
m∠4 = 180 - 41 = 139° (same interior angles)
Same interior angles are supplementary.
m∠5 = 41° (same interior angles)
m∠6 = 139° (vertically opposite angles)
m∠7 = 41° (vertically opposite angles)
4.
m∠1 = 117° (alternate exterior angles)
Alternate exterior angles are congruent
m∠2 = 180 - 117 = 63° (sum of angles on a straight line)
m∠3 = 117° (vertically opposite angles)
m∠4 = 63° (vertically opposite angles)
m∠5 = 117° (vertically opposite angles)
m∠6 = 180 - 117 = 63° (sum of angles on a straight line)

-2r+t=4
Answers
Solve equations
-(1) + 6 = 5
5= 5
-2(1) + 6 = 4
4=4
_________
Step by step
We have two equations
-r + t = 5 to t = r + 5 when put in y intercept form for easy math
t = r + 5
-2r + t = 4
To solve, substitute the t value from the first equation for t in the second
-2r + (r + 5) = 4
Combine like terms
-1r + 5 = 4
Subtract 5 from both sides to solve for r
-1r + 5 - 5 = 4 - 5
Combine
-1r = -1
Divide both sides by -1 to solve for r
-1/-1 r = -1/-1
r = 1
Now substitute the r value into one of the equations to solve for t
(-1)(1) + t = 5
-1 + t = 5
Subtract (-1) from both sides to solve for
t = 6

Higher Order Thinking Veronica needs to buy 13 pounds of cheese. When the clerk places some cheese in a container and weighs it, the scale shows 1 pounds. The container weighs pound. How many more pounds of cheese should be added to the scale to get the amount that Veronica needs? Explain how you solved the problem.
Answers
After calculating some basic arithmetic we have come to find that, 12 pounds of more cheese should be added to the scale to get the amount that Veronica needs which 23 pounds.
What is arithmetic?Using the four operations, arithmetic is a branch of mathematics that deals with the characteristics of numbers.
Division, multiplication, and subtraction are the four operations. The rules for each operation are very detailed.
As an illustration of arithmetic, one of the rules of addition and subtraction is that addition increases the overall value of a number while subtraction decreases the overall value of a number.
Veronica needs to buy 13 pounds of cheese
Cheese in a container weighs = 1 pounds
Mass of cheese clerk needs to add = 13 - 1
= 12 pounds
(as 1 pound is already there)
Thus, 12 pounds of more cheese should be added to the scale to get the amount that Veronica needs which 23 pounds.

Answers
The value of the composite function (f o g)(x) is 8x - 17
How to evaluate the function?The definition of the functions are given as
f(x) = 4x - 1
g(x) = 2x - 4
The composite function definition is given as
(f o g)(x)
This composite function is calculated using the following composite function formula
(f o g)(x)= f(g(x))
Substitute the known values in the above equation
So, we have the following equation
(f o g)(x) = 4(g(x)) - 1
So, we have the following equation
(f o g)(x) = 4(2x - 4) - 1
Open the brackets
(f o g)(x) = 8x - 16 - 1
Evaluate
(f o g)(x) = 8x - 17
Hence, the composite function is (f o g)(x) = 8x - 17

Number of small boxes:
Answers
Number of large boxes will be 65.
Number of small boxes will be 70.
What is mathematical expression?
Expression in math is defined as the collection of the numbers, variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The large boxes weigh 40 pounds each, and the small boxes weigh 25 pounds each.
There are 135 boxes in all.
If the truck is carrying a total of 4350 pounds in boxes.
Let number of large boxes = x
Number of small boxes = y
Since, There are 135 boxes in all.
So, We get;
x + y = 135 ... (i)
And, The large boxes weigh 40 pounds each, and the small boxes weigh 25 pounds each and the truck is carrying a total of 4350 pounds in boxes.
So, we can formulate;
40x + 25y = 4350 ... (ii)
Solve equation (i) and (ii) as;
Multiply 40 by (i) and subtract by (ii) we get;
40x + 40y - 40x - 25y = 5,400 - 4,350
15y = 1,050
y = 70
And, x + y = 135
x + 70 = 135
x = 135 - 70
x = 65
Thus, Number of large boxes will be 65.
Number of small boxes will be 70.

It can also be described as the point at which the three medians intersect.The median is a line that connects the midpoints of two sides and the opposite vertex of a triangle. A triangle is a two-dimensional shape with three sides. The three angles add up to 180 degrees.The centroid of a triangle divides the triangle's medians in a 2: 1 ratio.The ratio of the two sides will be given here as:

"Glen chooses a marble first and then Kris chooses one" You have to determine the probability of Kris choosing a yellow marble if Glen chooses a yellow one first.
1. First you have to determine the probability that Glen choose a yellow marble first.
To do so, you have to calculate the quotient between the number of yellow marbles on the bag and the total number of marbles on the bag:
[tex]\begin{gathered} P(Y_1)=\frac{nº\text{yellow}}{\text{total}} \\ P(Y_1)=\frac{3}{5} \end{gathered}[/tex]2. and 3.
After Glen takes the first yellow marble from the bag, the total number of marbles is reduced by one and so is the number of yellow marbles on the bag, so:
New total: 4 marbles
Number of yellow marbles: 2

To determine the probability of Kris choosing a yellow marble, you have to use the data on the remaining marbles on the bag. And calculate the quotient between the remaining number of yellow marbles and the remaining number of marbles:
[tex]\begin{gathered} P(Y_2)=\frac{2}{4} \\ P(Y_2)=\frac{1}{2} \end{gathered}[/tex]
