Barbara orders her groceries from a store that charges $15 plus the cost of her groceries to deliver her groceries to her home.

crimeas [40]

Answer:

The correct answer is Total Cost Payable = $Exp + $15, where $Exp is the total price of the groceries bought by Barbara

Step-by-step explanation:

Barbara orders her groceries. Let us consider that she orders groceries worth $Exp from a store.

Extra charges levied by the store for delivering the groceries to Barbara's house is $15.

Thus the total payable charge by Barbara for her groceries should include the total price of the groceries and the delivery charges levied by the store.

Thus the Total Cost Payable by Barbara is the sum of the total expenditure by her on the groceries and the delivery charge.

∴ The total cost payable = $Exp + $15.

A 1080 foot cable weighs 307 pounds. How much will 36 inches of cable weigh? Round to 2 decimal places

noname [10]

Answer:

0.85 pounds

Step-by-step explanation:

1080 foot cable = 307 pounds

36 inches/2.9999988ft = (2.9999988 x 307) / 1080 = 920.9996316/1080 = 0.85277743666 pounds ≈ 0.85 pounds

1 inch = 0.0833333 ft

36 inch = 36 x 0.0833333 = 2.9999988 ft

Alberto wants to keep their favorite tree from being uprooted by heavy winds. They plan to tie 3 sections of rope to a band on t

motikmotik

Answer:

39 ft

Step-by-step explanation:

Using the description as a guideline I have drawn out the situation (badly drawn) as seen in the picture below. From the picture, we see that we need to find x which is the length of one of the ropes. Once we have this length we simply multiply it by 3 to find out how much rope we need altogether. Since this is the diagonal of a triangle we can use the Pythagorean theorem to solve for x.

Pythagorean theorem: $a^{2} +b^{2} = c^{2}$ .... which a and b are the two sides while x is the diagonal.

$5^{2} +12^{2} = x^{2}$

$25 + 144 = x^{2}$

$169 = x^{2}$ ... now we square root both sides

$13 = x$

Now that we have the length of one of the ropes we simply multiply this by 3 to find the total amount of rope needed.

13 * 3 = 39 ft

PLEASE HELP I WILL GIVE BAINY LIST TO WHOEVER ANSWERS ALL THE QUESTIONS !!!!!

sergejj [24]

Answer:

1. $97\frac{3}{4}$

2. $3$ x $6\frac{3}{4}$ = $20\frac{1}{4}$

3. $77$ $\frac{1}{2}$

4. Yes (explanation given below)

Step-by-step explanation:

1. Find the area of the wall including the door...

Just multiply the numbers for the width and length.

$11\frac{1}{2}$ x $8\frac{1}{2}$ = $97\frac{3}{4}$

And now, as you can see.

$97\frac{3}{4}$ is our answer for 1.

2. Find the area of the door. (improper fraction)

Again, we just have to multiply, then simplify, and remember to keep it in improper fraction format.

$3$ x $6\frac{3}{4}$ = $20\frac{1}{4}$

so now, we can see that that is the area of the door, but according to the question, we have to leave the answer in the improper fraction format. To turn a mixed number into a improper fraction, we have to multiply the denominator of the fraction with the whole then, add the numerator, the answer that we get is going to be the numerator of the improper fraction and the denominator remains the same.

20 1/4 = 81/4 (improper fraction)

So, 81/4 is our answer for 2.

3. Without door space, give how much wall area there is. (mixed number)

So, as we already know that the door covers up 20 $\frac{1}{4}$ , so all what we have to do is, take the area of the Whole wall and door and subtract it by the door area.

WHOLE wall = 97 $\frac{3}{4}$

Door only = 20 $\frac{1}{4}$

$97\frac{3}{4}-20\frac{1}{4} = 77\frac{1}{2}$

So, hence, the answer for 3. is 77 $\frac{1}{2}$

4. Does Amelia have enough paint? Explain...

Yes, amelia has enough paint for covering the whole intire wall because she has enough paint for a 100 square feet, and the actual surfact area of her wall is JUST 97 3/4 square feet. So, she definitely has enough paint to cover that wall and door.
