MIDNIGHT HOMEWORK -1 5/6 divided by (-3 1/3 plz help me

Answer:

10,000 * (0.5)^x/19 ; 19.53125

Step-by-step explanation:

Sorry, Im not good at chemistry, but I think this is how you do it.

Part 1: 10,000 * (0.5)^x/19 x=time

Part 2: 10,000 * (0.5)^171/19 = 10,000 *(0.5)^9 = 19.53125

Answer:

hope this helps

Step-by-step explanation:

31 divided by 2 = 15.5 then do 15.5 x 15.5= 240.25 then you do 240.25 x 3.14 = 754.385

You're correct!!

Answer:

[tex]4 \frac{1}{2} [/tex]in²

Step-by-step explanation:

The area of the larger rectangle minus the area of the smaller rectangle

Area of the larger rectangle

= 3×2.5

= 7.5 in²

Area of the smaller rectangle

= 2×1.5

= 3 in²

The area of the shaded region

= 7.5-3

= 4.5 in²

Answer:

Step-by-step explanation:

Use the volume of a sphere formula and then multiply it by .5 to get half of it, since a hemisphere is half of a sphere. Doing that gives us the formula:

[tex]V=\frac{4}{3}\pi r^3\frac{1}{2}[/tex] which simplifies to

[tex]V=\frac{2}{3}\pi r^3[/tex] . Now, filling in what we were given:

[tex]45729=\frac{2}{3}\pi r^3[/tex] which simplifies a bit to

[tex]137187=2\pi r^3[/tex]. We divide by 2π to get

[tex]2183.98918=r^3[/tex] and take the cubed root on your calculator to get that

r = 27.9"

[tex]Volume= 45729in^3\\\\[/tex]

[tex]Radius=r[/tex]

[tex]2/3\pi r^3=45729[/tex]

[tex]r^3=3*45729\\~~~~------\\~~~~~~2*3.14[/tex]

[tex]r^3=21845.06[/tex]

[tex]r=27.95~in[/tex]

hope it helps...

have a great day!!

Answer:

8 1/3 or 8.33 yards per second

Step-by-step explanation:

100/12 = 8 1/3

Answer:

Solution given:For A

height [h]=9units

breadth[b]=9units

for both cylinder and cone

Volume of container A=volume of cylinder -volume of cone

=πr²h-1/3×πr²h=π(9²)9-1/3×(9²)9

so first option is your answer.

a. π(92)(9) − 1 over 3π(92)(9)

Answer:

1.86

Step-by-step explanation:

Since decimals are the same as fractions, we can convert 4/5 to .80. And since "of" means multiply, we can convert .80 of 9.3 to:

.8 x 9.3 = 7.44

This is the amount of pears, so we subtract:

9.3 - 7.44 = 1.86

The weight of the apples is 1.86.

Answer:

A translation of 5 units to the right, followed by a reflection across the x axis.

Answer:

x=0, y=-2

Step-by-step explanation:

6x0=0

2(-2)=-4

so, -4=-4 so it is determined true

Then 0-2(-2), -2(-2)=4

subtract 0 from 4 which is 4

so, 4=4, so it is determined true

Answer:

[tex]y=\frac{4}{3}x -8[/tex]

Step-by-step explanation:

So first find the slope of the given line

-2 - 4 = -6

4 + 4 = 8

-6 ÷ 8 = [tex]-\frac{3}{4}[/tex]

The slope of a line perpendicular to another line is the opposite reciprocal of the given slope.

The opposite reciprocal of [tex]-\frac{3}{4}[/tex] is [tex]\frac{4}{3}[/tex]

So now all we need to finish the slope intercept form y = mx + b is b, which is the y intercept.

[tex]y=\frac{4}{3}x+b[/tex]

Now that they give us the X intercept, you can plug in the values (6, 0).

[tex]0=8+b[/tex]

b = -8

Answer:

400 & 2

Step-by-step explanation:

Alright, so for the first question you do 14 + 6 which = 20 and if you do 20 × 20, it equals 400.

And for the second one 14 - 12= 2.

Answer:

i don't know that language sorry

Step-by-step explanation:

Answer:

8 months and $320

Step-by-step explanation:

To find when 30m + 80 = 40m, isolate m.

30m + 80 = 40m

Subtract 40m from both sides.

-10m + 80 = 0

Subtract 80 from both sides.

-10m = -80

Divide both sides by -10

m = 8

To find the cost, substitute 8 as m in one of the equations.

40(8) = 320

Answer:

37 inches

Step-by-step explanation:

to get 37 inches, you need to add 24 and 13. so 24+13 would equal 37.

Answer:

m=  1/2

y=1

Step-by-step explanation:

you go up 2 over 4 but you simplify it to 1/2

you then go to the first point for y intercept, which is 1 (because it follow the patteren)

Answer:

Taking 45 degree as reference angle

Then using sine rule

sin 45=

p/h

replacing the value of sin 45 degree by 1/root 2.so

1/root 2=9/c

doing cross multiplication

9*root 2=1*c

9 root 2 =c

therefore the value of c is 9 root 2

Answer:

The angle between the two blades is 120 degree.

Step-by-step explanation:

number of blades = 3

The blades are equally spaced.

The total angle around a circle is 360 degree.

So, the angle between the two blades is given by

[tex]\theta =\frac{360}{n}\\\theta =\frac{360}{3} = 120^{o}[/tex]

Answer: 22 batches of chocolate chip cookies

Step-by-step explanation:

A batch of cookies can take 0.25 cups of sugar to make.

You instead have 5.50 cups of sugar.

The number of batches that can be made is:

= Total amount of sugar available / Amount of sugar required for one batch

= 5.50 / 0.25

= 22 batches of chocolate chip cookies

Answer:

94 seats

Step-by-step explanation:

We solve using Arithmetic sequence formula

an = a + (n + 1)d

Where

a = First term = 49

d = Common difference = 52 - 49 or 55 - 52 = 3

n = 16th row

Hence,

a16 = 49 + (16 - 1)3

a16 = 49 + (15 × 3)

a16 = 49 + 45

a16 = 94

Therefore, the number of seats on the 16th row is 94 seats
