Answer:
$40
Step-by-step explanation:
You find the LCM (least common multiple). To do this, you can use prime factorization.
(there is an below that shows the prime factorization tree for 8 and 10)
so, the only common prime factor is 2. you use the 2 and multiply with the remaining prime factors.
5*2 --> for 10
2*2*2 -->for 8
becomes
5*2*2*2
if you multiply that out, it becomes 40.
Another method is to just think: "What can they both become after being multiplied by a number?" or "What can 8 and 10 both be?"
Anyway, the answer is 40. Hope this helps!

A plane traveled 336 miles to Carson City and back. The trip there was with the wind. It took 4 hours. The trip back was into the wind. The trip back took 6 hours. What is the speed of the plane in still air? What is the speed of the wind?
Answer:
Thus, train speed = 70 mph while wind speed is. y = 14 mph
Step-by-step explanation:
Let x = speed of the plane in mph.
Let y = speed of wind in mph.
We are told that The trip there was with the wind. It took 4 hours. The trip back was into the wind. The trip back took 6 hours.
Formula for distance is;
Distance = speed × time
Thus;
(x + y)4 = 336
(x + y) = 84 - - - - (1)
Also;
(x - y)6 = 336
Divide both sides by 6
(x - y) = 56 - - - (eq 2)
Add eq 1 and 2 to give;
2x = 84 + 56
2x = 140
x = 140/2
x = 70 mph
Plug in 70 mAh for x in eq 1.
(70 - y) = 56
y = 70 - 56
y = 14 mph
Thus, train speed = 70 mAh while wind speed is. y = 14 mph

Jordan bought 4 shirts
that each cost the same
amount and I pair of
jeans that cost $40.
The items he bought cost
a total of $180 before
tax. What was the cost of
each shirt?
Answer:35 dollars each
Step-by-step explanation: Because if you take the $40 out of 180 you get 140 then you divide 140 by 4 and you get 35. Hope this helps.
a rectangle has a length of x3y4 inches and a width of xy7 inches . Which expression represents the ratio of the length of the rectangle to do width of the rectangle? (NEED HELP ASAP)
Answer:
A. x²/y³
Step-by-step explanation:
Given the following data;
Length = x³y⁴
Width = [tex] xy^{7}[/tex]
Ratio = length/width
[tex] Ratio = \frac{x^{3}y^{4}}{xy{^7}}[/tex]
Simplifying the equation by applying the law of indices (division), we have;
[tex]\frac{x^{3}}{x} = x^{3} - x^{1} = x^{3-1} = x^{2} [/tex]
[tex]\frac{y^{4}}{y^{7}} = y^{4} - y^{7} = y^{4-7} = y^{-3} [/tex]
Hence, rearranging the above values;
[tex] Ratio = \frac{x^{2}}{y^{3}}[/tex]
Therefore, the expression that represents the ratio of the length of the rectangle to the width of the rectangle is A. x²/y³.

A complex number is a number system that extends the real numbers with a particular element labelled "i" known as the imaginary unit. The correct option is D.
What is a complex number?A complex number is a number system that extends the real numbers with a particular element labelled "i" known as the imaginary unit, and satisfies the equation i² = -1; every complex number may be represented as a + bi, where a and b are real numbers.
To find the conjugate of a complex number, we change the sign of the complex part of the number. Therefore, the conjugate of -14-2i is -14+2i.
The modulus of the given complex number -14-2i is,
|z| = √[(-14)²+(-2)²]
= √(196 + 4)
= √200
= 10√2
Hence, the conjugate and modulus of –14 – 2i are -14+2i and 10√2, respectively.

The manager of hockey team says that the probability that team win the next match is 0.5 and the probability it will lose is 0.2. Find the probability that the team will: a ) not win b) not lose c) not draw
Answer:
Step-by-step explanation:
The team draws with a probability of 1 = (0.5 + 0.2) = 0.3
If the team does not win then it loses or draws.
Loosing = 0.2
Draw := 0.3
P(not win) = 0.2 + 0.3 = 0.5
======================
Not lose means wins or draws.
P(not lose) = 0.5 + 0.3 = 0.8
======================
Not Draw means wins or loses
P(not draw) = 0.5 + 0.2 = 0.7
Of course all of these could be done more directly.
P(not win)= (1 - win) = 1- 0.5 = 0.5
P(not lose) = ( 1 - lose) = 1 - 0.2 = 0.8
P(not draw) = (1 - 0.3) = 0.7
