My soccer team has 16 players. I have to choose a starting lineup of a goalie and 10 regular players (the regular players are interchangeable). How many different starting lineups can I choose?
Answer:
48048
Step-by-step explanation:
Total number of players = 16
Selection to be made :
1 goalie ; 10 players
Hence ;
Choosing 1 goalie from 16 players :
16C1
Choosing 10 players from the remaining (16 - 1), 15 players
15C10
Hence,
16C1 * 15C10
16 * 3003
= 48048

Mrs. Trainer baked 120 cookies. She decided to give 1/6 of them to her students. How many did she take to her students?
Answer:
20
Step-by-step explanation:
120/6=20
20x1=20
Answer:
20 cookies
Step-by-step explanation:
What we know:
- Mrs. Trainer baked 120 cookies
- 1/6 of the 120 cookies went to her students
To find the number of cookies that Mrs. Trainer gave to her students, multiply 120 by 1/6.
[tex]120*\frac{1}{6}\\= \frac{120}{6} \\[/tex]
Simplify the fraction
[tex]= 20[/tex]
Therefore, Mrs. Trainer gave 20 cookies to her students.
I hope this helps!
Walmart is selling 100 mL tubes of toothpaste for $1.79 or 150 mL of toothpaste for $2.19. Which is the better buy?
Answer:
1.79/100mL = 0.0179
2.19/150mL = 0.0146
so, look at the end numbers
0.0179
0.0146
0.0146 is less than 0.0179
soo, $2.19 / 150mL = 0.0146 is the better buy...

Answer:
x = [tex]11\sqrt{2}[/tex]
y = [tex]11\sqrt{2}[/tex]
Step-by-step explanation:
the ratio of the sides of a 45 - 45 - 90 triangle is shown at the bottom of this answer.
as you can see, it is x:x:[tex]x\sqrt{2}[/tex]
The side given is x[tex]\sqrt{2}[/tex], so you have:
[tex]x\sqrt{2}=22[/tex]
divide both sides by [tex]\sqrt{2}[/tex]
x = [tex]22/\sqrt{2}[/tex]
multiply this by [tex]\sqrt{2} /\sqrt{2}[/tex]
[tex]x = 22\sqrt{2}/2[/tex]
[tex]x=11\sqrt{2}[/tex]
y is also equal so y = [tex]11\sqrt{2}[/tex]

Answer:
there monthly budget is $4000
Step-by-step explanation:
if 600 is 15% then there is 85% of there budget left so in order to find how much is 1% then 600/15=40 so $40 = 1% so 1%x100=100% and 40x100=4000 so 100% of there budget is $4000
hope this helps have a blessed day :)

Answer: m∠5 = 75°.
Step-by-step explanation:
We know that lines A and B are parallel, and angles 1 and 5 are formed by the same line intersecting the parallel lines.
We know that:
"When a line intersects two parallel lines, corresponding angles are formed, such that we could think on four quadrants, the angles in each quadrant are equivalent between them"
Well, here we can see that angle ∠1 and angle ∠5 are formed by the same line, and both are in the same quadrant (would be the third quadrant if we use standard notation)
Then the measure of ∠1 is the same as the measure of ∠5
And we know that m∠1 = 75°
Then we must have that m∠5 = 75°.

High-definition televisions have an aspect ratio of 16: 9. The following answer choices are television screen sizes rounded to the nearest inch. Which could be a High-definition television?
Answer:
18.5 in approx
Step-by-step explanation:
Given data
aspect ratio of 16: 9
L= 16in
W= 9 in
We want to find the diagonal of the TV
applying Pythagoras theorem
d^2= l^2+w^2
d^2= 16^2+ 9^2
d^2=256+81
d^2= 337
d= √337
d= 18.35 in
Hence the tv is 18.5 in approx

A newspaper article reports the results of an election between two candidates. The article says that Smith received 60% of the votes and that Murphy received 15 of the votes. A reader writes in to complain that the article cannot be accurate. What reason might the reader have to say this?
Step-by-step explanation:
Since, smith receives 60% of the vote this means murphy must receive 40% of the vote. Therefore 15 = 40% of the total vote.
Thus total vote = 37.5, which is kind of absurd. As total vote count must be an integer. Moreover, the report must be consistent with the result, which does not seem in this case.

Answer:
3 = ?
Step-by-step explanation:
The triangles are similar, so we can use ratios
15 12 -2
------ = --------------
15+? 12
15 10
------ = --------------
15+? 12
Using cross products
15 * 12 = 10 ( 15+?)
180 = 10 ( 15+?)
Divide each side by 10
18 = 15+?
Subtract 15 from each side
18-15 = 15+?-15

How many 1/2 inch cubes does it take to fill a box with a width of 3 1/2 inches, length of 2 inches and height of 5 1/2 inches?
Answer:
Step-by-step explanation:
Remark
I'm going to assume that the edges of the cubes are 1/2 inch on each side.
V = 1/2 * 1/2 * 1/2 = 1/8 cubic inches.
Volume of the box
V = L * w * h
Givens
L = 2 inches
w = 3.5 inches
h = 5.5 inches
Solution
V = L * w * h
V = 2 * 3.5 * 5.5
V = 38.5
1/8 has the decimal equivalent value of 0.125
Number of cubes needed = Volume of the box / volume of the cube
Number of cubes needed = 38.5 / 0.125
Number of cubes needed = 308

Solve for x.
-3(4x-16)=-12
I need an answer and explanation so I can try to do some myself thanks!:)
Answer:
B. -5
Step-by-step explanation:
this is quite simple, so what you are going to want to do is multiply -3 by 4, and -16, so distribute that and you'll end up with
-12x+48= -12
then you want to subtract 48 from both side to leave the x on one side alone
that will be -12x= -60
after that you have to divide both sides by -12 to find your x
so then you will see that your x is = -5! hope this helps!!
