Keith spent 2 1/2 of hours doing chores. He spent 1/4 of that time dusting. How much time did Keith spend dusting? (number model)
Answer:
Keith spent 37 and a half minutes dusting.
Step-by-step explanation:
Given that Keith spent 2 1/2 of hours doing chores, and I have spent 1/4 of that time dusting, to determine how much time did Keith spend dusting, the following calculation must be performed:
1/2 = 0.5
1/4 = 0.25
2.5 x 0.25 = X
0.625 = X
1 = 60
0.625 = X
0.625 x 60 = X
37.5 = X
Therefore, Keith spent 37 and a half minutes dusting.

Miguel borrowed $825 for a new couch. He will make 9 monthly payments of $95 to repay the loan. How much will he pay in interest?
Answer:
$30 is paid in interest.
Step-by-step explanation:
The couch costs $825 and Miguel will pay 9 * $95 = $855. So the amount of interest paid is how much in total was paid $855 minuse the cost of the couch $825, or $855-$825 = $30 in interest

Find value of x that will make a||b
Answer:
x = 4
Step-by-step explanation:
If line A is parallel to line B, therefore,
9x + 4 = 5x + 20 (alternate interior angles theorem)
Solve for x. Collect like terms together
9x - 5x = -4 + 20
4x = 16
Divide both sides by 4
4x/4 = 16/4
x = 4
Therefore, the value of x that will make lime A parallel to line B is 4

A model rocket is launch from a platform 17 feet high in the initial velocity is 40 ft The path of the rocket is modeled by the equation 16x^2 +40X +17=0 When does the rocket land
Answer:
It will be in the air until P(x) is zero.
P(x) = -16x2 + 32x = -16x(x - 2)
P(x) = 0 ⇒ x = 0 or x = 2
It starts on the ground at x = 0, so the total time in the air must be x = 2 seconds.

What will be the coordinates of the image after a translation up 4 units and right 6 units
Answer:
B
Step-by-step explanation:
To find the answer, translate each point and then use the process of elimination.
For the first point, the coordinates are (-4, -2). The -4 is x and the -2 is y. Translations up and down relate to the y value, while translations left and right relate to x. To translate up 4 units, add 4 to the y value of the coordinate. -2 + 4 is 2, so the y coordinate of the first point will be 2. That eliminated A and D.
For the second point, translate up 4 units (-5 + 4) and you get -1. So the y value of the second point will be -1. In option C, it is positive 1. So that leaves only B.
Olivia wants to spend at most $259 on
video games.
If each video game cost $64, what is the
maximum number of games Olivia can
buy?
4 is the maximum number of video games Olivia can buy
Answer:
4 games
Step-by-step explanation:
Find the maximum number of games she bought by dividing 259 by 64:
259/64
= 4.04
Since we can only have a whole number of games, we have to round this down.
4.04
= 4
So, the maximum number of games she can buy is 4.

The positions on a lacrosse team are called defenders (D), midfielders (M), and attackers (A). One player is chosen at random to lead the team in
exercises before each game. The letters MDD mean that a midfielder was chosen at the first game and a defender was chosen at the next two
games. The list of all possible outcomes is shown, where each outcome has equal probability of occurring.

The price of a watch was increased by 20% to £144. What was the price before the increase
Answer:
120 pounds
Step-by-step explanation:
Since the new cost is 144 pounds and this is 20% more, this is 120% of the original price. Remember 100+20 = 120. To find the original price set up a proportion with these values:
Solve for the original price by cross multiplying numerator with denominator.
x(120) = 144(100)
120x = 14400
x= 120 pounds
Find the missing side of each right triangle (Pythagorean’s #Theorem)
Answer:
3
Step-by-step explanation:
The formula for the Pythagorean's Theorem is a^2 + b^2 = c^2, so first you know that hypotenuse is the longest side or the opposite side from which the right angle is which in this case is the 6 so you are looking for a leg rather then the hypotenuse which means we are going to be doing subtraction.
a^2 + b^2 = c^2
√27^2 - b^2 = 6^2
27 - b^2 = 36
-27 -27
b^2 = 9
b^2 = √9
b = 34. Find the volume of the of the cylinder.

Answer:
[tex] V_{cylinder} =16,579.2\: in^3 [/tex]
Step-by-step explanation:
Inner radius [tex] (r_1)[/tex] = 20/2 = 10 in
Outer radius [tex] (r_2)[/tex] = 24/2 = 12 in
Height of the cylinder (h) = 120 in
[tex] \because V_{cylinder} =\pi( r_2^2-r_1^2) h[/tex]
[tex] \therefore V_{cylinder} =3.14(12^2-10^2) 120[/tex]
[tex] \therefore V_{cylinder} =376.8(12^2-10^2) [/tex]
[tex] \therefore V_{cylinder} =376.8(144-100) [/tex]
[tex] \therefore V_{cylinder} =376.8(44) [/tex]
[tex] \therefore V_{cylinder} =16,579.2\: in^3 [/tex]

Random samples of female and male UVA undergraduates are asked to estimate the number of alcoholic drinks that each consumes on a typical weekend. The data is below:
Females (Population 1): 2, 2, 2, 5, 5, 5, 1, 2, 3, 5
Males (Population 2): 5, 4, 5, 7, 4, 7, 5, 4, 4, 8
Give a 97.6% confidence interval for the difference between mean female and male drink consumption. (Assume that the population variances are equal.)
Confidence Interval =
Answer:
Confidence Interval =-3.4085 ,+0.7915
Step-by-step explanation:
The confidence interval can be determined by
(x1`- x2`) ± 1.955 √s1²/n1 + s2²/n2
The mean and the standard deviations can be calculated using the calculator.
The mean x1`= ∑x/ n= 2+ 2+ 2+ 5+ 5+ 5+ 1+2+ 3+ 5/10
= 32/10= 3.2
Standard deviation = s1`= 1.536
The mean x2`= ∑x/ n= 5 +4 +5+ 7+ 4+ 7+ 5+ 4+ 4+ 8/10
= 53/10= 5.3
Standard Deviation = s2= 1.4177=1.42
Putting the values
(x1`- x2`) ± 1.955 √s1²/n1 + s2²/n2
(3.2-5.3 ) ± 1.955 √1.54²/10 +1.42²/10
-2.1 ± 1.955 √ 2.37/10 +2.11/10
-2.1 ± 1.3085
-3.4085 ,+0.7915
9. Find the length AD of the shape given below, giving your answer correct to 2
decimal places.
Answer:
Length of AD = 10.47 meter (Approx.)
Step-by-step explanation:
Given:
Triangle ACB is a right angle triangle
Length of AC = 14.8 m
Length of CB = 5.5 m
Length of CD = 6.4 m
Find:
Length of AD
Computation:
Using Pythagorean theorem
Base = √Hypoteneus² - Perpendicular²
Length of AB = √14.8² - 5.5²
Length of AB = 13.74 m
Length of DB = √6.4² - 5.5²
Length of DB = 3.27
Length of AD = Length of AB - Length of DB
Length of AD = 13.74 - 3.27
Length of AD = 10.47
Length of AD = 10.47 meter (Approx.)

The starting annual salary for an office worker at a company is $29,000. If the company awards an annual increase of 6.2%, which graph models this situation after the office worker receives x annual increases?
Answer:
Graph A
Step-by-step explanation:
The line starts at around 29,000, including graph B
but 6.2% is not so huge, so the curve would be less.
B's curve is is very high, so it would not make sense.
