Step-by-step explanation:
The average number of points a basketball team scored for
three games was 63 points. In two games, they scored the same number of points,
which was 6 points more than they scored in the third game. Write and solve an
equation to find the number of points they scored in each game.
Solve for x. Show each step of the solution 4.5 ( 8 - x ) + 36 = 102 - 2.5 ( 3x + 24)
Answer:
X=-10
Step-by-step explanation:
Answer:
x = -10
Step-by-step explanation:
4.5(8-x) + 36 = 102 - 2.5(3x+24)
36 - 4.5x + 36 = 102 - 7.5x - 60
72 - 4.5x = 42 - 7.5x
72 + 3x = 42
3x = -30
x = -10
Henry sends his hawk with a message to his uncle. The hawk flies out against the wind and returns with the wind, spending 3 hours on the whole trip. How far is Henry's uncle from Henry if the speed of the wind is 5 mph, and the hawk flies 50 mph in quiet weather?
Answer:
Distance between Henry and his uncle is 74.25km.
Step-by-step explanation:
Speed of Hawk with wind = 50+5
=55km/hr
Speed of Hawk against wind = 50-5
=45km/hr
we know that ,
[tex]Distance = speed \times time[/tex]
Let the distance between Henry and uncle is d,
According to the question ,
[tex]\frac{d}{55} + \frac{d}{45} = 3[/tex]
[tex]\frac{9d + 11d}{495} =3[/tex]
[tex]20d = 3\times 495[/tex]
[tex]d =\frac{3\times495}{20}[/tex]
d= 74.25km
Hence , the answer is 74.25km
The relation between speed, time, and distance is used. Then the distance between Henry's uncle from Henry is 74.25 miles.
What is speed?The distance covered in an hour is called speed. it is a scalar quantity.
What is relative speed?The concept of relative speed is used when two or more bodies moving with some speed are considered.
Henry sends his hawk with a message to his uncle.
The hawk flies out against the wind and returns with the wind, spending 3 hours on the whole trip.
We know the relation
[tex]\rm speed = \dfrac{distance }{time}[/tex]
Let the distance between Henry's uncle from Henry be x.
The time of the trip is during the traveling remains constant. That is
[tex]\rm T = T_1 + T_2\\\\T = \dfrac{x}{v_1} + \dfrac{x}{v_2}[/tex]
The speed of the wind is 5 mph, and the hawk flies 50 mph in quiet weather. Then we have
[tex]\rm v_1 = 50 - 5 = 45\\\\v_2 = 50 + 5 = 55[/tex]
Then
[tex]\begin{aligned} \rm \dfrac{x}{45} + \dfrac{x}{55} &= 3\\\\\rm \dfrac{9x + 11x }{495} &= 3\\\\\rm 9x + 11x &= 1485\\\\\rm 20x &= 1485\\\\\rm x &= 74.25 \end{aligned}[/tex]
Thus, the distance between Henry's uncle from Henry is 74.25 miles.

Step-by-step explanation:
Let's arrange it in a proper manner first of all.
x² + 10x + 25Step: Spilt 10x in order to factorize it.
x² + 10x + 25
0r, x² + 5x + 5x + 25
Step: Make two pairs from equation
x² + 5x + 5x + 25
0r, x(x+5) + 5(x+5)
Step: Take common thing from the given equation
x(x+5) + 5(x+5)
0r, (x+5)(x+5)
Hence, (x+5) and (x+5) are the factor for the given equation.

1.5 lbs of gum balls I want to buy it’s 3.99 per pound
Answer:
$5.99 for 1.5 lbs of gumballs
Step-by-step explanation:
You want to buy One and a half pounds of gumballs for $3.99 per pound. It is 3.99 for one pound of gumballs, so the price for half a pound of gumballs is half of that price.
3.99 / 2 = 1.995
Then add the price of 1 pound
3.99 + 1.995 = 5.985
Then you can round that up to 5.99

express 7.84684846 as a rational number in the form p/q were p and q have no common factors
It's not clear what the pattern is supposed to be for the digits in the givne number. It looks like the repeating block should be 846, but it could just as easily be 84684.
Assume the first case, and let x = 7.846846846... . Then
1000x = 7846.846846846...
Subtract x from this to cancel the repeating decimal part, then solve for x :
999x = 7846 - 7 = 7839
x = 7839/999 = 871/111
If instead you meant the second case, let x = 7.846848468484684... . Then
10⁵ x = 784,684.846848468484684...
Solve for x :
99,999 x = 784,684 - 7 = 784,677
x = 784,677/99,999 = 261,559/33,333
Maybe you meant something else altogether?
what is the polar form of 7 √ 3-7i
Answer:
14(cos(330)+isin(330))
Step-by-step explanation:
step1: determine the modulus using the formula |z|=√(a²+b²)
|z|= √((7√3)² + (-7)²) = √196 = 14
step2: determine the argument using the formula θ=tan⁻¹(y/x)
θ= tan⁻¹(-7/7√3) = (-1/√3) --> rationalize the denominator by multiplying top and bottom by √3 to get: -√3/3
the tangent value on the unit circle that is -√3/3 is 330 degrees in quadrant iv

Find a pattern, then select the next two terms of the sequence.
5, 1, 7, 0, 9, –1, 11, . . .
Answer:
-2 and 13
Step-by-step explanation:
the pattern here is annoying to find, but there is one. the first change is -4, then +6, then -7, then +9. The pattern starts at -4, then after that it increases by 2 and changes from a negative to a positive (and can change the other way). After that change it increases by one and changes from a positive to a negative. Essiently, the pattern is add 2 to the pattern and change the sign, then add 1 to the pattern after that and change the sign, infinitely repeating, with the two after 11 being -2 (gotten from +12 because you add 2 to -10 and change the sign) and 13 (gotten from -13 because you add 1 and change the sign of +12).

D. 1/3
Answer:
C. √3
Step-by-step explanation:
When one of the factors is a rational number (0.5), the product will be irrational if, and only if, the other factor is irrational.
Of the numbers offered, only √3 is irrational.
√3 will produce an irrational product when multiplied by 0.5.

Jenna buys water from a store which allows you to bring your own containers of water and fill them up. The only catch is that you must honestly type into the store's computer how many gallons of water you took in total, written as a decimal, and then pay the amount the computer indicates.
Today, Jenna takes four containers with her. The first has a 3/4 gallon capacity, the second has a 1/8 gallon capacity, the third has a 4/5 gallon capacity, and the fourth has a 17/125 gallon capacity. She fills up all of the containers with water. What decimal should Jenna type into the computer?
Answer:
1.811
Step-by-step explanation:
To get the decimal Jenna should type into the computer you simply have to get the decimal value of each fraction and add them all together.
[tex]\frac{3}{4}=.75[/tex]
[tex]\frac{1}{8} =.125[/tex]
[tex]\frac{4}{5}=.8[/tex]
[tex]\frac{17}{125}=.136[/tex]
Then just add all the decimals together.
