Answer:

8 gallons at $7

12 gallons at $2

Step-by-step explanation:

x gallons at $7 with the remaining (20 - x) gallons at $2 to get 20 gallons at $4

x(7) + (20 - x)(2) = 20(4)

Distribute

7x + 40 - 2x = 80

Combine like terms

5x + 40 = 80

Subtract 40 from both sides

5x = 40

Divide both sides by 5

x = 8 gallons at $7

20 - x = 12 gallons at $2

Answer:

For one you would need 10 boxes of bags you would approximately need 98 bags.

for two The temp. would reach 33 degrees by December 15th.

for three.... I have no clue :/ If I figure it out I will get back to you

Step-by-step explanation:

1. 7 bags per yard, you have 14 yards so 14x7=98 which you should round to 100 bags which would be 10 boxes if each box has 10 bags  

2. all I did was follow the pattern (using a 2021 calendar so I wouldn't mess up the days)  went through months following the pattern every five days the temp. goes down by 3 degrees.

Joe would need to buy 10 boxes out of which 2 bags will be unused. The date on which temperature will be 33 degrees is 30th December. The schedule should be Monday, Wednesday, Friday, and Sunday.

1.

Given information:

Joe figured he would need approximately 7 bags per yard in which to collect the leaves.

The bags are sold 10 to a box, and Joe is planning on raking 14 yards.

The number of bags required to collect the leaves from 14 yards will be,

[tex]14\times7=98\rm\; bags[/tex]

So, the number of boxes required will be,

[tex]b=\dfrac{98}{10}\\b=9.8[/tex]

Since the number of boxes can't be a fraction. Joe would need to buy 10 boxes out of which 2 bags will be unused.

2.

Given information:

The high temperature on October 21st was 66 degrees, the high temperature on October 26th was 63 degrees and the high temperature on October 31st was 60 degrees.

The temperature on every fifth day forms an AP. SO, the AP will be 66, 63, 60, .....

It is required to find the date on which the temperature will be 33 degrees.

The place of term 33 in the AP will be,

[tex]a_n=a+(n-1)d\\33=66+(n-1)(-3)\\n-1=11\\n=12[/tex]

33 is placed in 12th position. So, after [tex]12\times5=60[/tex] days, the temperature will be 33 degrees.

Therefore, the date on which temperature will be 33 degrees is 30th December.

3.

Lou decided to be proactive about this and promised himself he would exercise at least four days of every calendar week.

Lou never wants to skip exercising on consecutive days within a calendar week.

He will work on consecutive days and four days a week. So, there is only one possibility to match the condition.

The schedule should be Monday, Wednesday, Friday, and Sunday.

Dividing 2/3 profit of selling concert tickets by 1/5 profit from selling band mechandise.

(2/3) / (1/5) = 10/3 = 3 1/3

Hence band members make 3 1/3 or 10/3 times more profit from ticket sales than from band merchandise sales.

This can be elaborate in such a way also.  

Let suppose the total profit is $30.

then the profit from the ticket sale = 2/3 of 30 = $20

and the profit from the band merchandise sales = 1/5 of 30 = $6

Now dividing 20 by 6, which gives 10/3. the same answer that were calculated above.

since they are all in the same line you only need to use 2 of the points I'm using (1,-1) and (2,1) next you do (x1,y1) and (x2, y2) which would be (1,2) and (-1, 1) then do y2-y1 / x2-x1 which would be 1/2

$48.81 x 0.07 = 3.4167

$48.81 + $3.4167 = $52.2267

$52.23

Step-by-step explanation:

The shirt cost $48.81, and the sales tax is 7%. First convert the 7% into a decimal and you get 0.07, and then multiply that to the $48.81. You get left with $3.4167 and then add that to the $48.81 to get $52.2267. But, you have to shorten the numbers to make it look like money by simplifing. So the total is $52.23.

Answer:52.17

Step-by-step explanation: You go to your calculator and type 7% × 48.81

to Stop anxiety attract

take a deep breath hold it for some time and then relax your body when exhaling

Don't think Brainly is the place to ask but If your not getting enough sleep, that can be why so make sure to SLEEP and take naps at around 1:00pm and Try to wake up at 3:00pm

Aerobic activity can be calming. Avoid caffeine, alcohol and smoking which act as triggers for the attack. Regular physical activity helps in releasing the anxiety.

Easier ways are to breathe slow and deep breathing is the cornerstone of calm. Start by breathing in and out slowly.

Drink more water. Dehydration may affect anxiety in a variety of ways. And raw fruits and vegetables are the best foods for panic attack because they act as antioxidants in your body.
