I need help with #6 plzzzz

Answers

First, find the unit rate.
Since the car travels 476 miles with 14 gallons of gas, then 476/14 = 34, so the car can travel 34 miles per gallon.

The distance is 34 times the number of gallons

d = 34g

Now you are given 578 miles, and you need to find the gallons.

578 = 34g

Solve for g by dividing both sides by 34.

g = 17

He needs 17 gallons.

Jordan has 260 basketball cards. He divides them into 4 equal groups. How many cards are in each group?

Answers

Jordan has 260 basketball cards and divides them evenly into 4 groups, resulting in 65 cards per group.

Jordan has 260 basketball cards and wants to divide them into 4 equal groups. To find the number of cards in each group, we need to perform a simple division. By dividing 260 by 4, we get:

Divide 260 by 4.

260 \/ 4 = 65.

Each group will have 65 cards.

Therefore, Jordan will have 65 basketball cards in each of the four groups.

The circle described by the equation (x - 3)² + (y + 4)² = 9 is translated 5 units to the left and one unit up.
At what point is the center of the image circle located?

A) (-8,5)
B) (8, -5)
C) (2, -3)
D) (-2, -3)

Answers

Greetings!

Answer:

New coordinates are (-2, -3)

Step-by-step explanation:

First we need the centre coordiates. In (x - a)² + ( y - b)² = r² , a is the x coordinate for the circle centre and b is the y coordinate for the circle centre, so this means the coordinate of the circle centre is:

(3 , -4)

If moving to the left 5 spaces, then 5 has to be subtracted from the x coordinate:

3 - 5 = -2

Now moving one up you add one to the y coordinate:

-4 + 1 = -3

So the new coordinates are (-2, -3)

A car is tracing at a rate of 72 kilometers per hour. What is the car rates in kilometers per min? How many kilometers will the car travel in 5 mins

Answers

1 hour= 60 minutes

72km/60 minutes= 1.2 km per minute

1.2(5)= 6 km

The car’s unit rate is 1.2 kilometers per minute and the car travel 6 kilometers in 5 minutes.

Hope this helps!

In 5 minutes, the car will travel 6 kilometers.

To convert the car's speed from kilometers per hour to kilometers per minute, we need to divide the given rate by the number of minutes in an hour, which is 60. So, for a car traveling at 72 kilometers per hour, the rate in kilometers per minute is:

72 km/hr / 60 = 1.2 kilometers per minute.

Now, to calculate how many kilometers the car will travel in 5 minutes, we simply multiply the rate in kilometers per minute by the number of minutes:

1.2 km/min * 5 min = 6 kilometers.

Therefore, the car will travel 6 kilometers in 5 minutes at the rate of 72 kilometers per hour.

Rachel earned 34 in 4 hours at her job today she wants to know how much she could earn (e) tommorow if she works 10 hours at the same hourly rate

A. E/34 = 4/10
B. 34/4 = E/10
Solve the proportion to determine how much Rachel will earn in 10 hours.

Answers

So she earned $34 in 4 hours, meaning she was earning at the rate of 34/4 or $8.5/hour.  Is she works for 10 hours at the same rate, it would be 8.5 x 10 = $85.  B is the correct proportion.
The correct equation of proportions would be $34                             x

_____  = ---------    Cross multiply:  ($34)(10 hr) = 4(hr)x
 4 hr         10 hr                                                                

Cancel "hr" on both sides.  Then $340 = 4x, and x = $85.

She could earn $85 working 10 hours.

Answers

B 16/100 is equivalent to 0.16
I'm assuming that this decimal terminates and none of the digits repeat forever. 

The 1 is in the tenths decimal place
The 6 is in the hundredths decimal place

So put together 0.16 is spoken out as "16 hundredths" meaning we have the fraction 16/100

We simply write the numbers after the decimal "16" over the value 100

Simplify the given expression (−3.5)(−3)(−6.4)

WE apply PEMDAS rule to simplify it

Lets start with parenthesis part

We multiply first two parenthesis

(−3.5)(−3)

Negative and negative becomes positive

(−3.5)(−3) is 10.5

Now we multiply it with -6.4. Positive times negative is negative.

One-third cup of black beans provides 20% of the potassium you need daily. You must get the remaining 1,360 milligrams from other sources. How many milligrams of potassium should you consume daily?

Answers

5×20%=100% so 1360mg is 80% of the daily requirement. The total requirement is 1360/0.8=13600/8=1700 mg.

80 percent of needed milligrams is 1360

so

1360/.80 = x/1  

1700 milligrams or 1,700 milligrams of potassium

If a line of one billion people standing shoulder to shoulder stretches 346,439 miles long, what is the average shoulder width, in feet, of the people in the line?

Answers

Final answer:

Given a line of one billion people extending for 346,439 miles, the average shoulder width of a person in the line is approximately 1.83 feet.

Explanation:

To find the average shoulder width of the people in the line, we need to convert the total miles into feet, since the result wanted is in feet. There are 5,280 feet in one mile. So the total length in feet would be 346,439 miles * 5,280 feet/mile = 1,829,029,920 feet. Now, if there are 1 billion people in this line, then the average width of a person's shoulders would be the total length divided by the total number of people. Hence, the average shoulder width = 1,829,029,920 feet / 1,000,000,000 people = approximately 1.83 feet.

or, 12b+16=4+6b

or, b= -2
Step 1. Distribute the 2 into the parenthesis ( we do this because the whole parenthesis and the 2 are multiplying)
Step 2. Get “b” by itself. ( to solve for a letter like b, we need to have it on one side of the equal sign)
Step3. Divide by 6 because we are undoing the multiplication of 6timesB. ( what you do on one side you do to the other side) divide the 6 into the -12.

Dane is 10 times Brian's age. The difference in their age is 27, how old is Brian

Answers

Brian is 3 years old.
Hope this helps!

Answer:

Brain is 3 years old.

Step-by-step explanation:

Let B represent Brain's age and D represent Dane's age.

We have been given that Dane is 10 times Brian's age. We can represent this information in an equation as:

[tex]D=10B...(1)[/tex]

We are also told that the difference in their age is 27. We can represent this information in an equation as:

[tex]D-B=27...(2)[/tex]

Upon substituting equation (1) i equation (2), we will get:

[tex]10B-B=27[/tex]

[tex]9B=27[/tex]

[tex]\frac{9B}{9}=\frac{27}{9}[/tex]

[tex]B=3[/tex]

Therefore, Brain is 3 years old.
