A dressmaker needs to cut 12-inch pieces of ribbon from rolls of ribbon that are 6 feet in length. How many 12-inch pieces can the dressmaker cut from 10 of these rolls of ribbon?
Before you try that problem, answer the question below.
How many \textbf{inches}inches of ribbon does the dressmaker have, in total?
Answer:
60
Step-by-step explanation:
because 12 inches is one foot so there’s 6 feet per 6 feet of ribbon and there’s 10 of these ribbons so 6 times 10 is 60
The 12-inch pieces the dressmaker can cut from 10 of these rolls of ribbon will be 60 strips .
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
It is given that the dressmaker has 720 inches of ribbon.
dressmaker needs to cut 12-inch pieces of ribbon from rolls of ribbon that are 6 feet in length.
The amount of rolls she has = 10 rolls
so,
6(strips per roll) x 10(amount of rolls) = 60 strips

If f(x) = 4x ^ 2 - 6 and g(x) = x ^ 2 - 4x - 8 , find (f - g)(x)
A. (f - g)(x) = 3x ^ 2 - 4x - 2
B. (f - g)(x) = 3x ^ 2 + 4x + 2
C. (f - g)(x) = 5x ^ 2 - 4x - 14
D. (f - g)(x) = - x ^ 2 - 14
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= (4x² - 6) - (x² - 4x - 8)
= 4x² - 6 - x² + 4x + 8
= 3x² + 4x + 2. (B)
what is the slope of the line that passes through the pair of points (5,-2) (0,-1)
Answer:
-(1/5)
Step-by-step explanation:
The slope is the Rise/Run between the two points (5,-2) and (0,-1):
Rise = -1 - (-2) = 1
Run = 0 - 5 = -5
Slope = Rise/Run = 1/-5 or -(1/5)
Point (0,-1) tells us that the y-intercept, b, is -1, so the full equation is:
y = -(1/5)x - 1
3.) Solve:
5x + 3- 3x = 2(x + 3) - 5
Answer:
0 = -2
Step-by-step explanation:
Answer:
no answer.
Step-by-step explanation:
5x + 3 - 3x = 2(x + 3) - 5 Simplify the left.
2x + 3 = 2(x + 3) - 5 Remove the brackets
2x + 3 = 2x + 6 - 5 Simply the right
2x + 3 = 2x + 1
It doesn't matter what you do, this is going to give you an impossible answer. The 2x's will cancel out and you will get 3 = 1 which is impossible.
Determine how the triangles are similar, if possible.
A: SAS
B: AA
C:Not similar
D: SSS
Answer:
The two triangles are similar by SAS postulate of similarity ⇒ A
Step-by-step explanation:
Let us revise the cases of similarity
AAA similarity: two triangles are similar if all three angles in the first triangle equal the corresponding angle in the second triangle AA similarity: If two angles of one triangle are equal to the corresponding angles of the other triangle, then the two triangles are similar. SSS similarity: If the corresponding sides of the two triangles are proportional, then the two triangles are similar. SAS similarity: In two triangles, if two sets of corresponding sides are proportional and the included angles are equal then the two triangles are similar.In the given figure
∵ There are 2 triangles
∵ The ratio between 2 corresponding sides in the Δs is [tex]\frac{28}{40}[/tex]
∵ [tex]\frac{28}{40}[/tex] = 0.7
∵ The ratio between the other 2 corresponding sides in the Δs is [tex]\frac{42}{60}[/tex]
∵ [tex]\frac{42}{60}[/tex] = 0.7
→ That means 2 sets of corresponding sides have an equal ratio
∴ The 2 sets of corresponding sides are proportional
→ By using the parallel sides
∵ There are two parallel sides
∴ The angles between the sides 28, 42, and the sides 40, 60 equal
because they are corresponding angles
∴ The included angles are equal in measures
→ By using case 4 above
∴ The two triangles are similar by SAS postulate of similarity
Find the measure of AngleQ, the smallest angle in a triangle whose sides have lengths 4, 5, and 6. Round the measure to the nearest whole degree.
Answer:
41
Step-by-step explanation:
41 degrees is the measure of AngleQ, when the smallest angle in a triangle whose sides have lengths 4, 5, and 6.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Given the side lengths PR = 4, RQ = 6 and PQ = 5
According to the law of cosine,
c=√a²+b²-2abcosФ
Substituting the values,
4=√5²+6²-2×5×6 cos∠Q
4=√25+36-60 cos∠Q
4=√25+36-60 cos∠Q
Take square on both sides
16=25+36-60 cos∠Q
16=61-60 cos∠Q
16-61=-60cos∠Q
-45=-60cos∠Q
Divide both sides by 60
cos⁻¹(45/60)=∠Q
41=∠Q
Hence, the measure of ∠Q is 41 degrees.

Solve 13+b>34. Graph the solution.
I give lots of points
Question:
13 + b > 34
Step 1: Keep variable on one side, and subtract 13 on both sides.
b > 21
Step 2: Now that you have the value of b, create a number line that includes the number "21"
Step 3: Since it is not "or equal too" we will use an open dot, since we do not contain that point. Put dot over 21.
Step 4: The sign is ( > ) meaning greater than. Therefore all points greater than 21 is true. See graph.

Find each product
To multiply these two binomials, we will use the F.O.I.L. method.
First-Outer-Inner-Last
First take the product of the first terms, which is 20x².
Then take the product of the outer terms which is 8x.
Then the product of the inner terms which is -20x.
Lastly take the product of the last terms which is -8.
Now let's combine like terms.
So our final answer is 20x^2 - 12x - 8.

2. Match the labeled points on the graph to statements about their coordinates. Please help I’ll give brainiest! Explain your answer!
Answer:
i - n ii - m
Step-by-step explanation:
Any coordinate on N has a sum of 2, any coordinate on M has a y that is 10 less than the x.
a)
The sum of the coordinates of each point is 2 is line n.
The y-coordinate of each point is 10 less than the x-coordinate is line m.
b)
The labeled points are given above.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
a)
Some of the coordinates of the line m.
= (10, 0), (13, 3), (6, -4)
The y-coordinate of each point is 10 less than the x-coordinate.
Some of the coordinates of the line n.
= (2, 0), (6, -4), (-2, 4)
The sum of the coordinates of each point is 2.
b)
Two points with a sum of 2.
= (2, 0) and (6, -4) on the line m.
Two points where the y-coordinate is 10 less than the x-coordinate.
= (10, 0) and (13, 3) on the number line n.
Two points with a sum of 2 and they-coordinate are 10 less than the
x-coordinate.
= no such points.
Thus,
a)
The sum of the coordinates of each point is 2 is line n.
The y-coordinate of each point is 10 less than the x-coordinate is line m.
b)
The labeled points are given above.
