Step-by-step explanation:

1 pound=16 ounces

so,

10 pounds=16 multiplied by 10= 160 ounces

Fun fact u spelled ounces at the very last.

pls can I have five star

The weight of the 10-pound package is 160 ounces.

There are 16 ounces in 1 pound. Juan is mailing a packet that weighs 10 pounds. To find the weight of the package in ounces, multiply the number of pounds (10) by the unit equivalence (16).

Therefore, the weight of the package is 160 ounces.

Answer:

16 is x<3

Step-by-step explanation:

4x-10<2

Add 10 to both sides

4x<12

Divide 4 from both sides and you get x<3

8 minutes is 2/15 of an hour when simplified, which is obtained by dividing both the numerator and denominator of the fraction 8/60 by the greatest common divisor of 8 and 60, which is 4.

To convert 8 minutes into a fraction of an hour, first understand that 1 hour is equivalent to 60 minutes. Therefore, to find what fraction 8 minutes is of an hour, you can create the ratio of 8 minutes to 60 minutes, which simplifies to:

8 minutes / 60 minutes = 8/60

This fraction can then be simplified by dividing both the numerator and the denominator by the greatest common divisor (GCD) of 8 and 60, which is 4, to obtain:

8/60 ÷ 4/4 = 2/15

Thus, 8 minutes is 2/15 of an hour in simplest form.

Answer:

w ≥ 141/2

Step-by-step explanation:

12 − 4/6 w ≤ 2/8 − 3/6 w

First, combine like terms.  Add 4/6 w to both sides, and subtract 2/8 from both sides.

12 − 2/8 ≤ 4/6 w − 3/6 w

12 − 2/8 ≤ 1/6 w

Reduce 2/8 to 1/4:

12 − 1/4 ≤ 1/6 w

To get rid of the fractions, multiply both sides by 12 (the LCM of 4 and 6):

12 (12 − 1/4) ≤ 12 (1/6 w)

144 − 3 ≤ 2w

141 ≤ 2w

Divide by 2:

141/2 ≤ w

If you'd like, flip the equation:

w ≥ 141/2

Answer:

100 seconds

Erica and Amy are at distance of 1 km in 100 seconds

Step-by-step explanation:

They both are travelling in opposite directions so the sum of the distances they travel is the distance between them.

Let's take t as the total time taken to achieve a seperation of 1km

Distance traveled by Erica , (Speed of Erica - v1)

x1 = v1 * t

Distance travelled by Amy , (Speed of Amy - v2)

x2 = v2*t

Therefore sum of the distances they traveled is x1+x2 = x

x = v1*t + v2*t

x = t*(v1 + v2)

Here it is given that final seperation between Amy and Erica is 1km or 1000 m

Therefore x = 1000 m

Thus t = [tex]\frac{x}{v1+v2}[/tex]

Substituting given values v1 = 6 m/s v2 = 4 m/s

Therefore,

They are apart by exactly 1km in a time of 100 sec

Answer:

A. $3,150

B. $2,100

Step-by-step explanation:

A. Given,

Trucks cost price = $40,000

Salvage Value = $8,500

Useful life = 10 years

Since there is no requirement, I am using straight-line depreciation method to calculate the depreciation expense.

We Know,

Depreciation Expenses = (Cost price - Salvage Value) / Useful Life

Therefore,

Depreciation expense = ($40,000 - $8,500)/10

Depreciation Expense = $31,500/10

Depreciation Expense = $3,150

Therefore, under the straight-line method, the depreciation expense will be = $3,150.

B. Given, (When the useful year is 15)

Trucks cost price = $40,000

Salvage Value = $8,500

Useful life = 15 years

Since there is no requirement, I am using straight-line depreciation method to calculate the depreciation expense.

We Know,

Depreciation Expenses = (Cost price - Salvage Value) / Useful Life

Therefore,

Depreciation expense = ($40,000 - $8,500)/15

Depreciation Expense = $31,500/15

Depreciation Expense = $2,100

Therefore, under the straight-line method, the depreciation expense will be = $2,100

Answer: 200cm long

Step-by-step explanation:

Let the length of the rod be x

red = 1/4 of the rod , which means 1/4 of x

orange = 2/5 of x

The remainder = x - ([tex]\frac{x}{4}[/tex] +[tex]\frac{2x}{5}[/tex])

= x - ([tex]\frac{13x}{20}[/tex])

= [tex]\frac{7x}{20}[/tex]

yellow = 2/7 of the remainder , that is

yellow = 2/7 of [tex]\frac{7x}{20}[/tex]

yellow = [tex]\frac{x}{10}[/tex]

and it was given that the yellow section was 20cm long , that is

[tex]\frac{x}{10}[/tex] = 20cm

x = 20 x10

x = 200

Therefore the rod was 200cm long

To determine the length of a rod based on fractions of it being painted different colors, with the yellow section known to be 20cm, we set up a proportion based on the fractions of the rod painted and use this to solve for the total length of the rod, which is 200cm.

The subject of this question is Mathematics, and it is typically encountered at the Middle School level. To find the length of the entire rod when 1/4 is painted red, 2/5 is painted orange, and 2/7 of the remainder is painted yellow with the yellow section being 20cm, we need to set up an equation and solve for the total length of the rod.

First, we determine the fraction of the rod that remains after painting 1/4 red and 2/5 orange:

Let's start the calculations:

1. (1/4) + (2/5) = 5/20 + 8/20 = 13/20.

2. The remaining fraction = 1 - 13/20 = 7/20.

3. Let x be the total length of the rod. Since 2/7 of the remainder is 20cm, we can write the equation (2/7) * (7/20) * x = 20cm.

4. Simplify and solve for x:

(2/7) * (7/20) * x = 20cm,

(1/10) * x = 20cm,

x = 20cm * 10,

x = 200cm.

Therefore, the total length of the rod is 200cm.

Each birdhouse needs 63 nails. If Willa uses only 7 nails on each side, she will need a total of 49 nails.

Each side of the birdhouse requires 9 nails, and there are 7 sides on the birdhouse. To find the total number of nails needed for each birdhouse, we can multiply the number of nails per side by the number of sides:

9 nails/side x 7 sides = 63 nails needed for each birdhouse.

If Willa only uses 7 nails on each side, the total number of nails she uses will change. The new total number of nails can be found by multiplying the new number of nails per side (7 nails) by the number of sides (7 sides):

7 nails/side x 7 sides = 49 nails in total.

∵ 3x(x + 2x) = 11

- Add the terms in the bracket

∴ 3x(3x) = 11

- Simplify the left hand side

∴ 9x² = 11

- Subtract 11 from both sides

∴ 9x² - 11 = 0

∵ The coefficient of x² = 9

∴ a = 9

∵ There is no x term

∴ b = 0

∵ The numerical term = -11

∵ The coefficient of x² = 4

∴ a = 4

∵ The coefficient of x = -48

∴ b = -48

∵ The numerical term = -4

Answer:

[tex]x=-\frac{88}{3}[/tex]

Step-by-step explanation:

When a quantity "A" varies DIRECTLY with another quantity "B", we can write the proportionality equation as:

A = kB

Where k is the proportionality constant (to be found)

In this problem, it is given x varies DIRECTLY with y, so we can write:

x = ky

Also, given, x = 11, y = -3, so we plug these into the equation and first find k:

x = ky

11 = k(-3)

k = -11/3

Now, we need to find x when y = 8, so we substitute and find x:

[tex]x=ky\\x=(-\frac{11}{3})(8)\\x=-\frac{88}{3}[/tex]

To find x for a given value of y when x varies directly as y, determine the constant of proportionality using the provided pair of values. Then use this constant to calculate x for the new value of y.

Since x varies directly as y, we can write this as x = ky, where k is the constant of proportionality. To find the value of k, we use the given values: x=11 when y=-3. Substituting these values into the equation gives us 11 = k(-3), or k = -11/3.

To find x when y=8, we substitute y=8 and the value of k into the direct variation equation: x = (-11/3)(8) = -88/3 = -29.33. Therefore, x is approximately -29.33 when y=8.
