Answer:
the fourth answer choice
Step-by-step explanation:
Here we're dividing one fraction by another. To accomplish this, invert the divisor (the second) fraction and multiply instead:
4m^12 8m^3
------------ * ----------
x + 1 x^2
Multiplying the two numerators together results in 32 m^15. This matches the fourth answer choice.

Solve –3d + 5 = 14.
–57
12
–27
–3
Answer:
d = -3
Step-by-step explanation:
–3d + 5 = 14.
Subtract 5 from each side
–3d + 5-5 = 14-5
-3d = 9
Divide each side by -3
-3d/ -3 = 9/-3
d = -3
Answer:
[tex]d = - 3[/tex]
last answer is correct
Step-by-step explanation:
[tex] - 3d + 5 = 14 \\ - 3d = 14 - 5 \\ - 3d = 9 \\ \frac{ - 3d}{ - 3} = \frac{9}{ - 3} \\ d = - 3[/tex]

A boat can travel with a speed of 13 km/hr in still water. If the speed of the stream is 4 km/hr, find the time taken by the boat to go 68 km downstream
Answer:
t=4h
Steps below
Step-by-step explanation:
We know:
speed of boat with respect to earth: 13 km
speed of stream with respect to earth: 4 km
13 km/h + 4 km/h = 17 km/h The time to travel 68 km with this speed is thus t = 68 km 17 km h = 4 h

Find the perimeter of a regular hexagon with a side of 8 meters
Answer:
8 x 6 = 48
Step-by-step explanation:
Hexagon = 6 sides
8 x 6 = 48
Answer:
48 meters
Step-by-step explanation:
A regular hexagon has six sides, all six sides are the same length. So you have to add 8 meters six times. Or just multiply 6 by 8. So you get 48 meters.
Does every line have a slope and a y intercept?
Answer:
see below
Step-by-step explanation:
Not every line has a y intercept because vertical lines ( lines that go up and down) do not intersect the y axis
Does every line have slope? It depends on how you define slope
Vertical lines have a slope that is undefined. So they have a slope that is undefined. When you are asked what the slope of a vertical line is , you answer undefined
Answer:
no
Step-by-step explanation:
because the line can be 0

In the NBA, any shot made from 22 feet or more from the basket is worth 3 points. How many yards from the basket is that?
Answer:
22/3 yards, roughly 7.33 yards.
Step-by-step explanation:
We know that there is 3 feet in 1 yard.
Given 22 feet, we divide by 3 to find the amount of yards, thus changing the unit.
The exact amount of yards is just 22/3, which you can estimate to 7.33 yds.

The dimensions of a rectangle are x+4 and 3x-1. Write an expression to represent the area of the rectangle.
Answer:
9x^4 - 6x^3 + 97x2 - 88x + 16
Step-by-step explanation:
so (x + 4)(x + 4) = x^2 + 8x + 16 is the total length of the rectangle, and
(3x - 1)(3x - 1) = 9x^2 - 6x + 1, if you multiply each other, because Area = length times width, then you get the area.
(9x^2 - 6x + 1)(x^2 + 8x + 16) = 9x^4 + 72x^2 + 144x^2 - 6x^3 - 48x^2 - 96x + x^2 + 8x + 16, and then you add them all together = 9x^4 - 6x^3 + 98x^2 - 96x + 8x + 16 = 9x^4 - 6x^3 + 97x2 - 88x + 16

Please help with this conditional probability question.
Answer:
8/45
Step-by-step explanation:
1. Since the dice has six sides and only two numbers are less than three (2 and 1) that means there is a 4/6 (2/3) chance of them rolling any other number besides 2 and 1. Since in bag two it has the yellow dice.
2. In bag two there are a total of 15 beads (4 yellow and 11 blue) since we want to get the yellow bead that means there is a 4/15 chance of getting a yellow bead.
3. Finally to find the chance of rolling a number greater than 2 and picking a yellow bead you must multiply the numerators and denominators. 2(4) and 3(15) which in turn equals 8/45.
If (x + y)^2 = 1 and xy = -4, what is the value of x^2 + y^2?
Answer:
[tex](x + y)^{2} = 1\\xy = -4\\x^{2} + y^{2} \\= x^{2} + 2xy + y^{2} - 2xy \\= (x^{2} + 2xy + y^{2}) - 2xy\\= (x+y)^{2} - 2xy\\= 1 - 2 *(-4) \\= 9[/tex]

Angela and Tyler are selling tickets for a charity football game. Students will get a discount for the game. Angela sells 6 adult ticket and 10 student ticket for $122. Tyler sells 11 adult tickets and 5 student tickets for a total of $157. What is the of an adult ticket and what is the price of a student ticket?
A, Define your varibles and write a system of equations that represents the ticket sales for both Angela and Tyler.
let x=
Let y=
system of equation:
B' Solve system of equation
c' Write answer using a complete sentence.
Answer:
Step-by-step explanation:
Let’s say that the price of an adult ticket is x and a student ticket is y.
we know that 6 adult tickets (6x) and 10 student tickets (10y) equal 122, so 6x+10y=122. Then, 11x+5y=157
6x+10y=122
11x+5y=157
Multiply the first equation by -1/2 and add it to the second to cancel out the y
8x=96
x=12
Plug this back in to equation 2 to find y
132+5y=157
y=5
Checking this with the first equation, it all works out.
The price of an adult ticket for a charity football game is $12, while the price for a student ticket for the same game is $5
When 240 sixth-grade students were polled, results showed that 96 students were dissatisfied with the music played at the school dance. What percentage of the sixth-grade students does this represent? Use at least 2 strategies.
Answer:
40%
Step-by-step explanation:
one strategie is doing proportions
96/240= ?/100
simplify 96/240= 2/5
so 2/5=?/100
multiply 100 by 2
then divide it by 5
another strategie is putting it into a decimal and percent
96/240= 2/5
in decimal is 0.40
move the decimal twice to the right and you get 40%

Which expression should you simplify to find the 90% confidence interval,
given a sample of 64 people with a sample proportion of 0.55?
Step-by-step explanation:
CI = p ± z √(pq/n)
For 90% confidence, z = 1.645.
CI = 0.55 ± 1.645√(0.55 × 0.45 / 64)
The expression to find the 90% confidence interval is
[tex]CI = 0.55 + 1.645 \sqrt{\frac{0.55 ( 0.45)}{64} }[/tex]
What is confidence interval?A confidence interval is a range of estimates for an unknown parameter. A confidence interval is computed at a designated confidence level; the 95% confidence level is most common, but other levels, such as 90% or 99%, are sometimes used.
CI z
0.70 1.04
0.75 1.15
0.80 1.28
0.85 1.44
0.90 1.645
0.92 1.75
0.95 1.96
0.96 2.05
0.98 2.33
0.99 2.58
According to the question
Data of people = 64
Data proportion (P) = 0.55
The 90% confidence interval
therefore, [tex]z_{c}[/tex] = 1.645
CI = P± [tex]z \sqrt{\frac{P ( 1-P}{N} }[/tex]
substituting the value
[tex]CI = 0.55 + 1.645 \sqrt{\frac{0.55 ( 0.45)}{64} }[/tex]
CI = 0.5563
Hence, expression to find the 90% confidence interval is
[tex]CI = 0.55 + 1.645 \sqrt{\frac{0.55 ( 0.45)}{64} }[/tex]
