One thumbtack weighs 0.25 ounce. How many thumbtacks are in a box that has a mass of 3500 grams? (Hint: 1oz ~28g

Answers

Answer 1

Answer: Alright so .25 oz is 1/4 of 1oz. Therefore you take 28 and divide it by 4 and get 7.

Then take 3500 and divide it by 7 which makes 500 thumb tacks.

I think idk though.

Answer 2

Answer:

Final answer:

To find out how many thumbtacks are in the box, first convert the total mass of the box from grams to ounces using a conversion factor. Then, divide the total weight of the box in ounces by the weight of one thumbtack.

Explanation:

To answer the question about the number of thumbtacks in a box totaling 3500g in mass, we first need to convert the total mass of the box to the same units as the mass per thumbtack, in this case, ounces.

From the relationship, we know that 1 oz = 28.349 g. We can convert the mass of the box into ounces by multiplying the grams by the unit conversion factor. So the weight of the box in ounces is 3500 g * (1 oz / 28.349 g).

To find the number of thumbtacks in the box, then divide the total weight of the box in ounces by the weight of one thumbtack in ounces (0.25 oz).

What does k equal in kx+2y=k; if (2,-2)

Answers

k(2)+2(-2)=k
2k-4=k
+4 +4
2k=k+4
-k -k
K=4

Simplify both sides of the equation

k(2)+(2)(-2) = k

Simplify

2k-4 = k

Subtract k from both sides

2k-4-k = k-k

k-4 = 0

Add 4 to both sides

k-4+4 = 0+4

k = 4

Yolanda spends 8 2⁄3 hours per month playing soccer. Approximately how many hours does she play soccer in a year? (There are twelve months in a year.)

Answers

Convert the mixed fraction into an improper fraction:

$8 * 3 = 24$
$24 + 2 = 26$

$8(2)/(3) = (26)/(3)$

Multiply the amount hours Yolanda plays per month by how many months there are in a year:

$(26)/(3) * 12 = (312)/(3)$

Simplify the fraction:

$312 / 3 = 104$

Yolanda spends 104 hours playing soccer in a year.

8.667 X 12 = 104(approximately)
because 2/3 =0.666666666666

Wyatt room is a rectangular with a perimeter of 40 feet. the width of room is 8 feet .what is the length of the room

Answers

width= 8ft
lenght=x
Perimeter of a rectangle=2 length + 2 width

Therefore:
2x+2(8 ft)=40 ft
2x+16 ft=40 ft
2x=40 ft-16ft
2x=24 ft
x=24 ft/2
x=12 ft

Answer: the lenght of the room will be 12 ft.

perimiter=2(legnth+width)
perimiter=40
width=8
40=2(legnth+8)
divide both sides by 2
20=legnth+8
minus 8 both sides
12=legnth

legnth=12 feet
