Answer:
1/6 yards
Step-by-step explanation:
Pipes available = 4/6 yards
Pipes used = 1/2 yards
Pipes left = total pipes bought - she doesn't suit that way
Pipes left = Total pipes available - pipes used
= 4/6 yards - 1/2 Yards
= 4-3/6
= 1/6 yards
Pipes left = 1/6 yards

Tanisha plans to invite 24 people to a snack. Each package contains 8 invitations. How many invitation packages should you buy?
Answer: 3
Step-by-step explanation:
From the question, we are informed that Tanisha plans to invite 24 people to a snack and that each package contains 8 invitations.
The number of invitation packages that should be bought will be the number of people to be invited divided by the invitations in each package. This will be:
= 24/8
= 3 invitation packages
Find (fºg)(1)
f(x) = x² - 1
g(x) = √x
A.0
B.1
C.4 √2
D. √8
Given:
The function are
[tex]f(x)=x^2-1[/tex]
[tex]g(x)=\sqrt{x}[/tex]
To find:
The value of [tex](f\circ g)(1)[/tex].
Solution:
We have,
[tex]f(x)=x^2-1[/tex]
[tex]g(x)=\sqrt{x}[/tex]
We need to find the value of [tex](f\circ g)(1)[/tex].
[tex](f\circ g)(1)=f(g(1))[/tex] [tex][\because (f\circ g)(x)=f(g(x))][/tex]
[tex](f\circ g)(1)=f(\sqrt{1})[/tex] [tex][\because g(x)=\sqrt{x}][/tex]
[tex](f\circ g)(1)=f(1)[/tex]
[tex](f\circ g)(1)=(1)^2-1[/tex] [tex][\because f(x)=x^2-1][/tex]
[tex](f\circ g)(1)=1-1[/tex]
[tex](f\circ g)(1)=0[/tex]
The value of [tex](f\circ g)(1)[/tex] is 0.
Therefore, the correct option is A.

.John has $40. He will use some of the money to buy books, and he wants to have at least $10 left to put in his savings account. Each book costs $6. A. Write an inequality to represent this story, using b to represent the number of books John buys. B. Solve the inequality, showing each step of your work. C. In complete sentences, explain what the solution means in the context of the story
Answer:
The required inequality is [tex]40-6b\leq 10[/tex].
Jhon can buy at most 5 books.
Step-by-step explanation:
Consider the provided information.
Part(A)
Let b represent the number of books John buys.
He wants at least $10 in his savings account which means if we subtract the cost of books from $40 we have at least $10 left.
[tex]40-6b\leq 10[/tex]
The required inequality is [tex]40-6b\leq 10[/tex].
Part(B)
[tex]40-6b\leq 10[/tex]
[tex]-6b\leq 10-40[/tex]
[tex]b \leq\frac{30}{6}[/tex]
[tex]b\leq 5[/tex]
Part(C): Jhon can buy at most 5 books.
Find the coordinates on f the point where y-4x=1 crosses the axis
Answer:
The coordinates of the intercepts are (0,1) and [tex]\left(-\frac{1}{4},0\right)[/tex]
Step-by-step explanation:
Intercepts of a Function
Given a function y=f(x), the intercepts with the x-axis, if any, can be found by solving the equation:
y = f(x) = 0
The intercepts with the y-axis can be found by calculating
f(0)
We are given the function
y - 4x = 1
To find the x-intercepts, set y=0:
0 - 4x = 1
Solving:
[tex]x = -\frac{1}{4}[/tex]
For x=0:
y - 4*0 = 1
y = 1
The coordinates of the intercepts are (0,1) and [tex]\left(-\frac{1}{4},0\right)[/tex]

A and B are two cylinders that are mathematically similar.
The area of the cross-section
of cylinder A is 18 cm?
18 cm?
B
10 cm
А
5 cm
Work out the volume of cylinder B.
Answer:
Volume of B is 360 [tex]cm^{3}[/tex]
Step-by-step explanation:
It can be observed in the question that the dimensions of cylinder B are twice the dimensions of cylinder A, since both are similar.
Height of B = 2 x height of A
= 2 x 5
= 10 cm
cross sectional area of B = 2 x cross sectional area of A
= 2 x 18
= 36 [tex]cm^{2}[/tex]
Thus,
Volume of B = cross sectional area x height
= 36 x 10
= 360 [tex]cm^{3}[/tex]
Volume of B is 360 [tex]cm^{3}[/tex].

A person invests 9000 dollars in a bank. The bank pays 4.75% interest compounded quarterly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 12600 dollars?
A=P(1+nr)nt
Answer:
The time required to get a total amount of $ 12,600.00 from compound interest on a principal of $9000 at an interest rate of 4.75% per year and compounded 4 times per year is 7.1 years.
Step-by-step explanation:
Given
Principle P = 9000 dollars
Rate r = 4.75% = 0.0475
Total Amount A = 12600 dollars
compounded quarterly n = 4
To determine:
Time t = ?
Using the equation
[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}[/tex]
solving the equation for 't'
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(12,600.00/9,000.00) / ( 4 × [ln(1 + 0.011875/4)] )
t = 7.1 years
Therefore, the time required to get a total amount of $ 12,600.00 from compound interest on a principal of $9000 at an interest rate of 4.75% per year and compounded 4 times per year is 7.1 years.

What is the area of rectangle RSTU? Show step by step!
Plz help me and solve this ASAP! Solve ASAP! Plz! Thank you!
Step-by-step explanation:
We only know 1 side, and that is the width of 4. We only have the diagonals at our side. Half of the diagonal is 5. As a result, the diagonal is 10. I want you to imagine a triangle that has a base of 4 and a hypotenuse of 10. Use the Pythagorean Theorem to find b, or the height.
a² + b² = c²
4² + b² = 10²
16 + b² = 100
100 - 16 = 84
b² = 84
b = √84
b ≈ 9.165
Now we know the length of the rectangle, which is about 9.165. Multiply that by 4 to get the area.
9.165 * 4
36 + 0.4 + 0.24 + 0.020
36.4 + 0.24 + 0.02
36.64 + 0.02
36.66 u²
The area of rectangle RSTU is about 36.66 units squared.

An angle measures 16° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
the surface are of a rectangle box of 5cm long, 3cm wide and 4cm wide is 94cm²
The measure of two supplementary angles are 82° and 98°.
What are supplementary angles?Supplementary angles refer to the pair of angles that always sum up to 180°. These two angles are called supplements of each other.
Given that, an angle measures 16° more than the measure of its supplementary angle.
Let the measure of one angle be x.
Then, the other angle is x+16°.
Now, x+x+16°=180°
2x+16°=180°
2x=164°
x=82°
So, x+16°=82+16°=98°
Therefore, the measure of two supplementary angles are 82° and 98°.
