Janet can make 3/4 of a necklace in 10 minutes. At this rate, how many necklaces, to the nearest tenth of a necklace,can janet make in 1 hour?
SHOW WORK
Answers
Answer: 2.3
Step-by-step explanation:
Janet can make 3/4 of a necklace in 10 minutes.
We need to find how many necklaces she can make in 1 hour.
1 hour = 60 minutes
We can rewrite it as:
1 hour = 3*(20 minutes)
So Janet can create three 3/4 necklaces in 1 hour
Therefore, the total necklaces Janet can make in 1 hour = 3*(3/4) = 9/4 = 2.25
To the nearest tenth of a necklace = 2.3 necklaces

Lamonte and Fwam own competing taxicab companies. Both cab companies charge a one-time pickup fee for every ride, as well as a charge for each mile traveled. The equation y=2.2x+2.5 represents what Lamonte's company charges. Fwam charges a $4 pickup fee and $2.80 per mile. Use the dropdown menu and answer-blank below to form a true statement.
Answers
The cab rate model for Fwam will be given as y=2.8x+4.
What is an equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Here we have an equation model for Lamonte y=2.2x+2.5 here y is the total cost and x is the distance in miles.
So here Fwam charges a $4 pick up fee and $2.80 per mile. The equation model will be:-
y=2.8x+4.
Hence cab rate model for Fwam will be given as y=2.8x+4.

if x = 5, then 3x + 4x - 15 equals = ?
Answers
Answer:
If x = 5, then 3x + 4x - 15 equals 20
Step-by-step explanation:
Here, we are given the value of x, which is 5.
1. Substitute 5 as the value of x in the equation:
3x + 4x - 15 = ?
3(5) + 4(5) - 15 = ?
15 + 20 - 15 = ?
2. Simplify:
15 + 20 - 15 = ?
35 - 15 = ?
20 = ?
3. Check your work:
3x + 4x - 15 = 20
3(5) + 4(5) - 15 = 20
15 + 20 - 15 = 20
20 = 20 ✅
Therefore, if x = 5, then 3x + 4x - 15 equals 20

Answers
Check the picture below.
[tex](s)(s)=144\implies s^2=144\implies s=\sqrt{144}\implies s=12 \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{volume of the cube}}{(s)(s)(s)\implies s^3}\implies 12^3\implies 1728~in^3[/tex]
Answer:
1728 in³
Step-by-step explanation:
Given that,
→ Area = 144 sq in
Then the length will be,
→ a² = 144
→ a = √144
→ [ a = 12 ]
Formula we use,
→ V = a³
Now required volume will be,
→ a³ = 12³
→ 12 × 12 × 12
→ 1728 in³
Hence, the volume is 1728 in³.

Which graph represents the polynomial function f(x)=x^3+x^2−2x
Answers
By finding the roots of the polynomial, we conclude that the correct graph is the second one.
Which is the graph of the polynomial?
Here we have the polynomial:
[tex]f(x) = x^3 + x^2 - 2x[/tex]
To identify it, we need to find the roots, we can rewrite the equation as:
[tex]f(x) = x*(x^2 + x - 2)[/tex]
And we can rewrite the last part by using the Bhaskara's formula:
[tex]x = \frac{-1 \pm \sqrt{1^2 + 4*2} }{2} \\\\x = (-1 \pm 3)/2[/tex]
Then the roots are:
x = -2
x = 1
Then we rewrite:
[tex]f(x) = x*(x + 2)*(x - 1)[/tex]
So the roots are at x = 0, x = -2, and x = 1.
The graph with these roots is the second graph (top right).
