A 12-ounce can of beer contains the same amount of alcohol as a five-ounce glass of wine.
In a five-ounce glass of wine, the percentage of alcohol is 12%, which is the same in the 12-ounce can or bottle of beer, and 1.5 ounces of 86-proof liquor. Although a person under the influence of alcohol will have impaired judgment and therefore must avoid driving, doesn't matter what kind of alcoholic beverage they drink. Digestion of alcohol doesn't take place as soon as you drink it, it is absorbed in your bloodstream which reaches the brain and thus creates impaired judgment.

Charlotte’s weekly paycheck is based on the number of hours worked during the week and on the weekend. If she works 13 hours during the week and 14 hours on the weekend, she earns $250.90. If she works 15 hours during the week and 8 hours on the weekend, she earns $204.70. How much more does Charlotte earn per hour on the weekends than she earns during the week? Round to the nearest cent.
$0.40
$1.90
$2.30
$8.10
The amount that Charlotte earn per hour on the weekends than she earns during the week is: C. $2.30.
How to find the earning per hour?Number of dollars earn per hour during the week = x
Number of dollars earn per hour on the weekend =y
Formulate an equation
13x + 14y = 250.90 Equation 1
15x + 8y = 204.70 Equation 2
Solving for x and y by multiply equation 1 by -8 and equation 2 by 14 -104x - 112y = -2007.20
210x +112y = 2865.80
106x = 858.60
Divide both sides by 106x
x = 858.60/106
x = $8.10
Substitute x into eq 1 so as to solve for y
13(8.10) + 14y = 250.90
105.30 + 14y = 250.90
Subtract 105.30 from both sides
14y = 145.60
Divide both side by 14y
y = 145.60 /14
y = 10.40
Hence,
Additional earning per hour = y-x
Additional earning per hour = $10.40 - $8.10
Additional earning per hour=$2.30 per hours
Therefore the correct option is C.

Sofia is 38 years old. Write an equation that relates Sofia's age to Tony's age, t. How old is Tony?
(Sofia’s age is 2 times the combined ages of Carlos and Lily - Carlos’s age is 4 more years than Tony’s age - and Lily’s age is one more than 6 times Tony’s age)
Answer:
Let s, c, y and t represent the ages of Sofia, Carlos, Lily and Tony respectively.
c + y = 2s ------ equation (1)
t + 4 = c ------ equation (2)
6t + 1 = y ------ equation (3)
Since Sofia is 38 years old, substitute s = 38 into equation (1):
c + y = 2(38)
= 76 ------ equation (4)
Substitute equations (2) and (3) into equation (4):
t + 4 + 6t + 1 = 76
7t + 5 = 76
7t = 71
∴ t = 10 (to the nearest whole number)
∴Tony is 10 years old (to the nearest whole number).

a client who weighs 70 kg is receiving a solution of 0.9% sodium chloride (normal saline) 500 ml with dopamine 800 mg at 5 ml/hour. how many mcg/kg/minute is the client receiving? (enter the numeric value only. if rounding is required, round to the nearest tenth.)
1.904 mcg/kg/min is what the client receives.
The number of mcg/kg/minute = flow rate × concentration ÷ mass of client
Flow rate = 12 ml/ hour = 12 /60 = 1/5 = 0.2 ml/min
Formula:
Concentration = mass of dopamine/volume
mass of dopamine = 800mg
volume = 500ml
Concentration = 800/ 500
= 1.6 mg/ml
= 1.6 × 1000 mcg/mg
= 1600 mcg/mg
Here the mass of the client = 70kg
Now calculating mcg/kg/minute = flow rate× concentration÷ mass of client
= 0.08 ml/min × 1600mcg/ml ÷70 kg
= 320/70
= 1.904 mcg/kg/min

The speed of the faster car is 40 miles/hr.
both cars travel for same time , so let that time be 't'
car 1 :
distance travelled = 75 miles
let the speed of the car be = x miles/hr
∴ time (t) = distance / speed
t = 75 / x .............(1)
car 2 :
distance travelled = 100 miles
speed of the car is = x + 10 miles/hr ( already provided )
∴ time ( t) = distance / speed
t = 100/ (x+10) ..............(2)
now as the time for both the cases is same , so we equate eqn (1) and eqn (2) .
∴ 75/x = 100/ (x+10)
3x + 30 = 4x
x = 30
so the speed of the 1st car will be 30 miles / hr

Each sack will contain 12. 5 kg of potatoes.
Kelly assumes that 12. 5 kg is measured correct to the nearest 0. 1 kg.
(a) Does Kelly definitely have enough potatoes to fill 200 sacks?
You must show how you get your answer
Kelly fill 200 sacks with the weight of 2000 kg potatoes and in each sack, she can fill up to 12.5 kg of potatoes.
What is weight?The gravitational attraction of an item near the Earth or another celestial body toward the center of the body. The weight of an item is determined by its mass and the strength of the gravitational force. We use the following generic formula to compute weight: W = mg. Where 'W' is the object's weight,'m' is the object's mass, and 'g' is the acceleration due to gravity. The value of g on Earth is 9.8 m/s2. The most frequent definition of weight is the force imposed by gravity on a body.
Here,
weight of potatoes she has=2500 kg
weight of each sack that contain the potatoes=12.5 kg
with this, she can fill,
=2500/12.5
=200 sacks

this shows that the percentage in a normal distribution that is at most 1.65 sds above average is about 95%. explain why 1.65 is the right number of sds to use when constructing a 90% confidence interval. (6 points)
The correct number of Standard deviation to generate a confidence interval is therefore 1.65.
Given that;
This shows that the percentage in a normal distribution that is at most 1.65 standard deviation above average is about 95%.
Percentage above 1.65 SD equals 100 - 95 = 5.
Now, because of the symmetric distribution,
Percentage above 1.65 SD = % below 1.65 SD is what we can see:
Below 1.65 SD + between 1.65 SD below and 1.65 above + above 1.65 SD + % above 1.65 SD = 100%
=> 5% + between -1.65 SD below and 1.65 above + 5% = 100%

sells for $1.50 and each pound of grapes sells for $2.75. Arun made $130.25 from
selling a total of 66 pounds of raspberries and grapes, Determine the number of
pounds of raspberries sold and the number of pounds of grapes sold.
Answer:
41 pounds of raspberries and 25 pounds of grapes
Step-by-step explanation:
x = pounds of raspberries
y = pounds of grapes
1.50x + 2.75y = 130.25
x + y = 66 --> y = -x + 66
Substitute and solve for x:
1.50x +2.75(-x +66) = 130.25
1.50x - 2.75x + 181.5 = 130.25
150x - 275x + 18150 = 13025
-125x +18150 = 13025
-125x = -5125
x = 41

The amount of water after x minutes is more in which pool? Pool A or Pool B?
Amount of water after x minutes is more in pool B.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Pool A started with 5000 liters of water, and 50 liters per minute are being.
Pool B started with 4800 liters of water, and 30 liters per minute are being.
5000-50x=4800-30x
Add 30x on both sides
5000-50x+30x=4800-30x+30x
5000-20x=4800
5000-4800=20x
200=20x
Divide both sides by 20
20=x
Now substitute x in pool A equation
5000-50x
5000-50(20)=5000-1000
Pool A =4000
Now substitute x in pool B equation
4800-30x
4800-30(20)
