Question:

A carpenter sands 1/2 of a dresser in 3/4 hour. At this rate, how long does it take the carpenter to sand 1 dresser?

Answer:

[tex]1\ dresser = \frac{3}{2} hour[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{2} dresser = \frac{3}{4} hour[/tex]

Required

How long will it take to sand 1 dresser

[tex]\frac{1}{2} dresser = \frac{3}{4} hour[/tex]

Multiply both sides by 2

[tex]2 * \frac{1}{2} dresser = \frac{3}{4} hour * 2[/tex]

[tex]1\ dresser = \frac{3}{4} hour * 2[/tex]

[tex]1\ dresser = \frac{3}{2} hour[/tex]

Hence;

It'll take 3/2 hour to sand 1 dresser

What are the coordinates of G, H, and I after a rotation about (0,0) by 90 degrees clockwise? Thank you.

Answers

Answer:

Ok, when we have a point (x, y) and we do a rotation of 90° the new points will actually depend on the quadrant where we are, but it will always change the order to (y, x) but this does not end here, because depending on the quadrant where the point ends, the signs will change as follows.

1st quad (+y, +x)

2nd quad (-y, +x)

3rd quad (-y, -x)

4th quad (+y, -x)

So if we are in the second quadrant, the transformed point will be in the first quadrant

Now, we have that the points G and H are:

G = (-1, 3)

This point is in the second quadrant, so it moves to the first quadrant (where bot values must be positive).

The new point will be:

G´ = (3, 1)

And the other point is:

H = (-4, 0)

It also rotates to the first quadrant, so the new point will be:

H' = (0, 4)

Answer:

Because the person above already explained I’ll just give the answers.

Step-by-step explanation:

G = (-1,3) H = (-4,0) I = (3,-2)

The federal tax code allows some items used for business purposes to be depreciated. That is, their taxable value decreases over time. A new van used in your delivery business has a taxable value of $22,000. The tax code allows you to depreciate this van by $1900 per year. Find a formula that gives the taxable value T, in dollars, of the van after n years of depreciation.

Answers

Answer: T = 22,000 - 1,900n

Step-by-step explanation:

Taxable value is $22,000

The tax code allows for the depreciation of this van by $1,900 per year.

After n years therefore the total depreciation is;

= 1,900 * n

This depreciation will need to be removed from the taxable value of $22,000 to find out the taxable value left.

Formula is therefore;

T = 22,000 - 1,900n

Complete Question

The complete question is shown on the first uploaded image

Answer:

The  value is  [tex]v(3) =  29.4 \  m/s[/tex]

Step-by-step explanation:

From the question we are told that

    [tex]s(t) =  -4.9t^2 + 500[/tex]

And  

    [tex]\lim_{t \to a}  \frac{s(a) - s(t)}{a-t}[/tex]

Generally s(t) at t = a is mathematically evaluated as

      [tex]s(a) =  -4.9a^2+ 500[/tex]

So

    [tex]s(a) - s(t) =  -4.9a^2 + 500 - ( -4.9t^2+500)[/tex]

     [tex]s(a) - s(t) =  -4.9a^2 + 500 +4.9t^2-500)[/tex]

      [tex]s(a) - s(t) = 4.9(t^2 - a^2)[/tex]

Thus the velocity is represented as

     [tex]v(t) =\lim_{t \to a}  \frac{s(a) - s(t)}{a-t} \equiv \lim_{t \to a} \frac{4.9(t^2 -  a^2 )}{ a-t}[/tex]

=>     [tex]v(t) = \lim_{t \to a}  - 4.9(a + t )[/tex]

=>      [tex]v(t) = -4.9 (a + a )[/tex]

=>      [tex]v(t) = -9.8a[/tex]

Now at  t =  3

=>  [tex]v(3) = -9.8 (3)[/tex]

=>   [tex]v(3) =  29.4 \  m/s[/tex]

The inventory of a restaurant needs replenishing of its supply of apples. The food supplier charges $7/bag of apples. The restaurant needs a 30 day-supply. If the restaurant uses 2 bags of apples per day, how much will it cost for a 30-day supply?


(You do not need to include the units. You only need to enter your answer as a number.)

Answers

if it’s 2 bags of apples a day for 30 days, then that’s 60 bags of apples total (30x2)

and if the charge for a bag is $7, then multiply 7 times your total number of bags (7x60) for the cost.

the answer should be $420

A chocolate company makes chocolate malt balls that have a radius of 0.34
inches. The carton they are to be packed in is approximately a rectangular prism with
dimensions 1.5 inches by 2.5 inches by 6 inches. How many malt balls will fit in the
carton

Answers

Answer:

Approximately 141 malt balls

Step-by-step explanation:

this problem is on the mensuration of solids shapes.

first we need to calculate the volume of the rectangular prism

volume of prsim= l*b*h

given that

length= 1.5 in

breath=2.5 in

hieght= 6 in

volume= 1.5*2.5*6

volume=22.5 in^3

secondly we then calculate the volume of a malt ball

given that

raduis r= 0.34

volume of sphere = 4/3πr^3

volume of sphere = 4/3*3.124*(0.34)^3

volume of sphere = 1.33*3.142*0.039

volume of sphere = 0.16 in^3

now we can calculate the amount of sphere that can fit into the prism as

= volume of prism/volume of sphere

= 22.5/0.16

=140.6

approximately 141 malt balls

2. A stock price rose 2.2 points in
Week 1. The stock price fell 5.4
points in Week 2. Write and solve
an equation to represent the total
price change in stock.

Answers

Answer: the total  price change in stock is fall of 3.2 points or -3.2 points.

Step-by-step explanation:

In integers , we use positive integers to show rise in amount whereas we use negative integers to show fall .

Given: A stock price rose 2.2 points in  Week 1.

i.e. +2.2 points rise.

The stock price fell 5.4  points in Week 2.

i.e. fall of -5.4.   (Much greater, than it rose)

The equation to represent the total  price change in stock would be

Total  price change = price rose in  Week 1 +  price fell  in Week 2.

= [+2.2 + (-5.4)] points

= 2.2 - 5.4 points   [ (+)(-) = (-)]

= -3.2 points

Hence, the total  price change in stock is fall of 3.2 points.
