Answer:
C.
-2.4=6x Since you're solving for x, the first thing you want to do is get x by itself. To do that you divide 6x by 6 and what you do one side of an equation you have to do to the other. SO now you should have 2.4/6=x Once you divide 2.4 by 6, you get your answer which is .4 Hope this helps!

Brian needs to make a total of 80 deliveries this week. So far he has completed 64 of them. What percentage of his total deliveries has Brian completed?
The percentage of his total deliveries has Brian completed is 80%.
What is percentage?
In a percentage, the total value is always 100, making it a ratio or fraction. For instance, Sam received a score of 30% on his arithmetic test, which is 30 out of a possible 100. In terms of ratio, it is expressed as 30:100 and as a fraction as 30/100. A certain portion or amount in every hundred is referred to as a percentage. The fraction is denoted by the sign "%," and its denominator is 100.
Here the given
Total number of deliveries = 80
The number of deliveries completed by Brian= 64
Now the percentage of deliveries completed by him is,
=> [tex]\frac{Number of deliveries completed by brian}{Total number of deliveries}[/tex] × 100
=> [tex]\frac{64}{80}[/tex] × 100
=> [tex]\frac{4}{5}[/tex] ×100
=>4×20 = 80%
Hence the percentage of his total deliveries has Brian completed is 80%.

Shawn's engineering club is taking a trip by bus to a robotics fair. The fair is 175 miles from Shawn's school. The bus driver plans to stop and refuel after 2 hours, then complete the trip. The bus driver plans to drive at an average speed of 50 miles per hour. How many hours will the second part of the trip take?
The second part of the trip would take 1.5 hours.
Speed is the ratio of the total distance travelled to total time taken. It is given by:
Speed = distance/time
Since the total distance is 175 miles at an average speed of 50 mph. Hence the total time is:
Speed = distance/time
50 = 175/time
time = 175/50
Time = 3.5 hours
Since the first trip takes 2 hours, the time needed for the second trip is:
Total time = time for first trip + time for second trip
3.5 hours = 2 hours + Time for second trip
Time for second trip = 1.5 hours
The second part of the trip would take 1.5 hours.

Which package has the better unit price per ounce?
Answer:
The 48-pack has the better unit price per bottle
Step-by-step explanation:
Given the two packages of same brand water bottles, where:
48-pack of 8 oz bottles = $5.88 28-pack of 10 oz bottles = $5.98We can compare which package has the better unit price per bottle by finding out how much each bottle costs, and the price per fluid ounce (fl oz) of each bottle.
48-pack:For the 48-pack, divide the total cost of $5.88 by the number of bottles for the whole package to determine the price of each bottle.
[tex]\mathsf{\frac{\$5.88} {48\:bottles}\:=\:\$0.1225\:per\:bottle}[/tex]
Next, divide the price per bottle by 8 ounces to find the cost per fluid ounce of the 48-pack:
[tex]\mathsf{\frac{\$0.1225} {8\:fl\:oz}\:=\:\$0.015\:per\:fl\:oz}[/tex]
28-pack:Similar to our solution for the 48-pack, we can determine the price of each bottle in a 28-pack by dividing the total cost of $5.98 by 28 bottles to determine the price of each bottle.
[tex]\mathsf{\frac{\$5.98} {28\:bottles}\:=\:\$0.21357\:per\:bottle}[/tex]
Next, divide the price per bottle by 10 ounces to find the cost per fluid ounce of the 28-pack:
[tex]\mathsf{\frac{\$0.21357} {10\:fl\:oz}\:=\:\$0.0214\:per\:fl\:oz}[/tex]
Answer:Therefore, the 48-pack of 8-ounce bottles has a better unit price per bottle of $0.12 than the unit price per bottle of the 28-pack of water bottles of $0.21.

write an equation of a line in slope intercept form that passes through (3,-2) and the slope is 1/6 then convert to standard form
Answer:
slope-intercept form: [tex]y=\frac{1}{6} x-\frac{5}{2}[/tex]
standard form: [tex]x-6y=15[/tex]
Step-by-step explanation:
To write an equation for the line with the only point as (3,-2) and the slope is [tex]m=\frac{1}{6}[/tex] we use the slope-intercept formula [tex]y=mx+b[/tex]
To convert an equation that is in slope-intercept form with fractions you have to multiply the denominator of each fraction on both sides of the slope-intercept form equation.
please help. i’ve been stuck on this question the past 10 minutes i’ve tried multiple times and still don’t get it. i need help please :/
Answer:
To solve the equation, you have to to isolate the variable. So, first you subtract both sides by 7.
x +7 - 7 = -2 - 7

There are 80 people in a choir.
Half the people in the choir are women.
The number of men in the choir is one quarter of the number of women.
The rest of the people in the choir are children.
the number of children in the choir : the number of men in the choir = n : 1
Work out the value of n.
You must show how you get your answer.
There are 30 children in the choir
Number of people in the choir = 80
Number of women = 1/2 × 80 = 40.
Number of men = 1/4 × 40 = 10
Therefore, the number if children will be:
Men + Women + Children = 80
10 + 40 + n = 80
n = 80 - 40 - 10
n = 50
There are 30 children in the choir.

Apples are 88 cents a pound if I have $6 how many pounds of apples can I buy with the $6 round to the nearest whole pound
Answer:
7 lbs
Step-by-step explanation:
Answer:
You can buy about 7 pounds of apples.
Step-by-step explanation:
Since we're dealing with cents, we'll change 88 to 0.88 so we can solve.
I personally did 0.88p = 6, where p = pounds, and then I divided 0.88 on both sides.
Of course you could just divide normally,
6 ÷ 0.88, either way it equals 6.81 repeating.
When you round that up, it will equal to 7.
Hope this helps :)
Michelle bought 12 cookies and 8 cupcakes for $72. Jana bought 5 of the same cookies and 10 of the same cupcakes for $50. What is the price of each item?
Answer:
Step-by-step explanation:
x = cookies
y= cupcakes
12x + 8y = 72
5x + 10y = 50
60x + 40y = 360
-20x - 40y = -200
40x = 160
x = $4 each cookie
12(4) + 8y = 72
48 + 8y = 72
8y = 24
y = $3 each cupcake
Assume that the mean of a dataset is 100 and the standard deviation is 5. If we multiply each value in the data by 2, what would be the new standard deviation?
Answer:
7
Step-by-step explanation:
Using statistical concepts, it is found that the new standard deviation of the variable would be of 10.
When a constant is multiplied to each data in a variable:
The mean is multiplied by this constant.The standard deviation is multiplied by this constant.In this problem, the standard deviation of the variable is 5, multiplied by 2, hence:
5 x 2 = 10
The new standard deviation of the variable would be of 10.

In what ways do you think tree planting is important? (Don’t use the internet)
Answer:
this is what I would say from my own opinion
Step-by-step explanation:
Tree planting is very important because trees give us oxygen and helps us live and helps keep the economy alive. The way trees are planted are very important because you have to care for it a lot. if it isn't done correctly then the tree will die. Trees need lots of water, sunshine. if the tree isn't correctly planted then it will just be a fail of getting a tree. millions of trees keeps us living and gives us lots of oxygen.
i will only say 3 ways
1.give it water
2.let it touch with sunlight
3.let it grow in soil
