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: 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°.

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

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 :)

The number of cell phones that employees at a factory can assemble is directly proportional to the number of hours the employees spend assembling cell phones. The employees can assemble 1,576 cell phones in 8 hours. If these employees continue to work at the same rate, how many cell phones will they assemble in 53 hours?
Answer:
10,441
Step-by-step explanation:
The number of cell phones the employees can assemble in 53 hours will be 10441.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
For example the speed 3meter/second.
As per the given,
1,576 cell phones in 8 hours.
Number of cell phones sells per hour or rate of change,
1576/8 = 197 cell phones/hour.
The number of cell phones sells in 53 hours,
197 cell phones/hour x 53 = 10441 cells phones.
Hence "The number of cell phones the employees can assemble in 53 hours will be 10441".

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

The values of x and y in the following equation system are 20 and 110, respectively.
What are System of equation?simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods to solving systems of equations: graphing, substitution, elimination and matrices.
given a system of equation:
30x + 4y = 1,040.....(1)
12x + 16y = 2,000...…(2)
We will solve it by using substitution method,
Multiply with 2.5 in equation (2) and subtract it from equation (1)
30x + 4y - 30x - 40y = 1040 - 5000
36y = 3960
y = 110
Substitute this value of y in equation (1)
30x + 440 = 1040
30x = 600
x = 20
Therefore, The value of x and y are 20 and 110 respectively for the given system of equation.

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
