Marcia made spiral books to sell at her local craft fair. She forgot to count how many she made before the fair. She knows that she spent $176.80 in supplies to make the books. If each book requires two chipboard covers at a cost of $0.74 per cover and one spiral wire at a cost of $0.60, which equation can be used to find the number of books, n, she made?
A. 0.60n + 0.74n = 176.80
B. 0.60n + 1.48n = 176.80
C. 0.60n + 0.74 = 176.80
D. 0.60n + 1.48 = 176.80
Answer:
B) 0.60n+1.48n = 176.80
Step-by-step explanation:
0.60 for every spiral wire per book = 0.60*n
0.74 per chipboard cover, 2 needed for each book = 1.48 per book = 1.48*n
Put it together: 0.60n+1.48n = 176.80

A line plot can be used as a data display for the distribution of test scores in math class. Thus, the option to choose is TRUE.
A line plot is a graph that shows data as checkmarks or dots across a number line, indicating the frequency of each value.
The test score in the math test will be discrete data with repeating frequencies. The score of every individual will moreover be a whole number.
The line plot, as we know, marks the dots across the number line, indicating frequency.
Thus, the scores in the math test can be displayed using a line plot, by indicating each type of mark on the line, and dots above those marks for the number of times the same marks occur.

Jill and Jack are exercising at a beach. They both start from the car park at one end of the beach. Jill runs at a constant speed and Jack walks at a constant speed. When Jill turns at the end of the beach to run back, she notices that Jack is then halfway along the beach. How far along the beach will Jack be when JIll next passes him
Jack is at (2/3) of the length of the beach (measuring from the point where they started).
How far along the beach will Jack be when JIll next passes him?Let's think that the whole beach is like a line track of length L.
We know that when Jill completes reaches the end (one complete run) Jack only completed half of it.
So in the time that jill covers the distance L, Jack covers a distance of L/2. So the ratio of their speeds is 2:1 (Jill's speed is double of Jack's speed).
At this point, Jill is on the end of the track and Jack is on the middle, so the distance between them is L/2.
Because of the ratios between the speeds, we know that when they meet again, Jill will have covered 2 thirds of that distance, and jack will cover the other third of that distance.
A third of that distance is:
(L/2)/3 = L/6
So, when they meet, Jack is at L/6 of the middle of the beach, which means that Jack is:
L/2 + L/6 = 3L/6 + L/6 = 4L/6 = 2L/3
Jack is at (2/3) of the length of the beach (measuring from the point where they started).

Solve for X. HELP?!
Answer:
x = 90
Step-by-step explanation:
In this figure the exterior angle is 130°
An exterior angle is the sum of the interior angles. The interior angles are x and 40 so x + 40 = 130 giving x = 130-40 = 90
Answer:
∠ x = 90°
(90 degrees)
Step-by-step explanation:
When two angles combine to make a straight line, we know that their angle values must add up to 180
Here, we can see that 130 combines with an inner angle to form a straight line. (I will be calling this interior angle z )
So, 130 + z = 180
130 + z = 180
- 130 -130
z = 50
We also know that all angles in a triangle must add up to 180 degrees, and because we know the two other angles of our triangle now, we can find x
z + x + 40 = 180
50 + x + 40 = 180
90 + x = 180
- 90 -90
x = 90
So, the measure of angle x is 90°

75 out of 300 oranges in a basket are bad. what percent age of the oranges are (a) bad (b)good
Answer:
a) 25% are bad
b) 75% are good
Step-by-step explanation:
We know that there are 300 oranges total and that 75 are bad. That means that the rest are good (implied).
300 - 75 = 225 good oranges.
So to find the percentage we have to take the selected amount divided by the total amount.
Bad Apples: Good Apples:
75 / 300 = 0.25 225/300 = 0.75
However, that's a decimal or a number out of 1, we need a percent or a number out of 100. So we have to multiply both numbers by 100.
Bad Apples = 25%
Good Apples = 75%

480 stamps must be given to Mark
Answer: 130 stamps.
Step-by-step explanation:
Let amount оf the stamps Debbie must give to Mark so that Mark have 120 more than she is x.
Hence,
(580+x)-(720-x)=120
580+x-720+x=120
2x-140=120
2x=260
2*x=2*130
x=130.
So, 130 stamps Debbie must give to Mark so that Mark have 120 more than she.

If the factors of a quadratic function are (x 2) and (x − 9), what are the x-intercepts of the function?
The x-intercepts of the given quadratic function are -2 and 9.
What is a quadratic function?
A quadratic function is a function represented as, f(x) = ax2 + bx + c, with a, b, and c being integers and a not equal to zero. A parabolic curve represents the graph of a quadratic function.
A polynomial's highest degree reveals how many roots the polynomial has. The values for which the polynomial's numerical value is equal to zero are known as a polynomial's roots (also known as zeros of a polynomial). On a graph, the points where the polynomial's graph and the x-axis cross are the roots (x-intercepts).
Roots of the Quadratic Equation
Due to its degree of 2, a quadratic function can only have a maximum of two real roots. In order to find the roots of a quadratic equation, we equate its factors to 0. Thus, in this case, we have,
(x+2)*(x-9)=0
∴ x+2=0
⇒ x=-2
Similarly,
x-9=0
⇒ x=9
Hence, the x- intercepts of the given quadratic function come out to be -2 and 9.
