Cleo bought 10 feet of ribbon for costumes. He used 2 feet of ribbon last week. He cut of the remaining ribbon into one- sixth foot pieces. How many pieces of ribbon does Cleo have?
Answer:
48 pieces
Step-by-step explanation:
Given:
Cleo bought 10 feet of ribbon.
He used 2 feet of ribbon last week.
He cut of the remaining ribbon into one- sixth foot pieces.
Question asked:
How many pieces of ribbon does Cleo have ?
Solution:
Total length of ribbon = 10 feet
He has used length of ribbon = 2 feet
Remaining length of ribbon = 10 - 2 = 8 feet
He cut remaining ribbon into = [tex]\frac{1}{6}foot[/tex]
Number of pieces of ribbon = [tex]8\div\frac{1}{6}[/tex]
= [tex]8\times6 = 48 pieces[/tex]
Therefore, Cleo have 48 pieces of ribbon.
Given that f(x)
equals
= 3x+2
and g(x)=x^2−2x−6
find (g◦f)(6).
(g◦f)(6) means we have to find g(f(6)).
So f(6)=3(6)+2=20
And g(20)=20^2-(20)(2)-6=400-40-6=360-6=354
So (g◦f)(6) is 354

The graph shows the relationship between the hours a soccer team practiced after the season started and their total practice time for the year. a. How many hours did the soccer team practice before the season began?
Answer:
6 hours
Step-by-step explanation:
The picture of the question in the attached figure
Let
x ----> the hours a soccer team practiced after the season started
y ----> the total practice time for the year in hours
we know that
The y-intercept of a linear equation is the value of x when the value of y is equal to zero
In the context of this problem, the y-intercept is the total practice time before the season began (the value of x is equal to zero)
Looking at the graph
The y-intercept is the point (0,6)
therefore
the total practice time before the season began is 6 hours

Answer:
The right answer is - 93 and none of the alternatives given is correct.
Step-by-step explanation:
Let's find the value of:
- 3 |15 –2 | + 2s³ , when s = -3
Replacing s, we have:
- 3 |15 –2 | + 2 * -3³
- 3 | 13 | + 2 * - 27
- 39 - 54 = -93

How do I solve these using the elimination method:
x+y+z=20
13x+0y+6z=132
150x+90y+139z=2601
Answer:
(x=6,y=5,z=9)
Step-by-step explanation:
The given system is
x+y+z=20 ------>(1)
13x+0y+6z=132 ------->(2)
150x+90y+139z=2601------>(3)
Make y the subject in the first equation to get: [tex]y=20-x-z-------(4)[/tex]
Put equation (4) in equation (3) to get:
150x+90(20-x-z)+139z=2601
150x+180-90x-90z+139z=2601
60x+49z=801---->(5)
We solve equation (2) and (5) simultaneously
13x+6z=132 ------->(2)
60x+49z=801---->(5)
Make x the subject in equation (2) to get:
[tex]x=\frac{132-6z}{13}[/tex]
Put it in (5)
[tex]60(\frac{132-6z}{13})z+49z=2601[/tex]
[tex]\frac{277z+7920}{13}=801[/tex]
[tex]277z+7920=10413[/tex]
[tex]277z=2493[/tex]
[tex]z=9[/tex]
[tex]x=\frac{132-6*9}{13}=6[/tex]
From 6+y+9=20
y=20-15=5

Siven that f(x)=x2 - 7 and g(x)= 4 - x, find (f - g)(1), if it exists.
Answer:
- 9
Step-by-step explanation:
Note that (f - g)(x) = f(x) - g(x)
f(x) - g(x)
= x² - 7 - (4 - x)
= x² - 7 - 4 + x
= x² + x - 11
Thus
(f - g)(1) ← substitute x = 1 into (f - g)(x)
= 1² + 1 - 11
= 1 + 1 - 11
= - 9
Select the smallest fraction from the following list of fractions. 2/3, 3/4, 1 1/2, 3/5, 2 2/3, 7/8
Answer:
The answer is 3/5
Step-by-step explanation:
Let's convert to decimals these fractions and mixed numbers to make the comparison and find out the smallest fraction, this way:
2/3 = 0.67
3/4 = 0.75
1 1/2 = 1 + 1/2 = 1.5
3/5 = 0.6
2 2/3 = 2 + 2/3 = 2.67
7/8 = 0.875
Now we observe that the lowest value is 0.6, therefore, the smallest fraction is:
3/5
To find the smallest fraction, compare and convert the fractions to have a common denominator. The smallest fraction from the given list is 7/12.
Explanation:To find the smallest fraction from the given list, we need to compare the fractions. One way to compare fractions is to make their denominators equal. Let's convert all the fractions to have a denominator of 12:
2/3 = 8/123/4 = 9/121 1/2 = 18/123/5 = 7/122 2/3 = 20/127/8 = 10.5/12From the conversions, we can see that the smallest fraction is 7/12.

Can someone explain this to me?
Answer:
y=42 degrees.
Step-by-step explanation:
The sum of angles in a triangle = 180 degrees.
One angle in that small triangle is y, one is 48, and one is unknown.
The sum of angles on one line is 180 degrees.
One of the angles on the line that unknown angle lies on is 90 degrees, so the unknown angle is 90 degrees, too.
90 + 48 = 138
180 - 138 = 42.
An object’s speed decreases by 6% for each minute that it is slowing down. What is the percent that it’s speed will decrease over half an hour?
solve this question
Answer:
PQ = 13 cm
Step-by-step explanation:
You need to use the Pythagorean Theorem twice.
On the base of the cuboid, mark the point opposite P, point A. Point A is vertically below point Q. Now draw a segment from point P to point A.
The distance from point P to point A can be found using the Pythagorean Theorem.
(3 cm)^2 + (4 cm)^2 = (PA)^2
9 cm^2 + 16 cm^2 = (PA)^2
25 cm^2 = (PA)^2
PA = 5 cm
Segment PA is a side of triangle PAQ. Angle PAQ is a right angle. Sides PA and AQ are legs of the right triangle, and side PQ is the hypotenuse. Now we use the Pythagorean Theorem again.
(PA)^2 + (AQ)^2 = (PQ)^2
(5 cm)^2 + (12 cm)^2 = (PQ)^2
25 cm^2 + 144 cm^2 = (PQ)^2
169 cm^2 = (PQ)^2
PQ = 13 cm
