The volume of the droplets in cubic meters would be = 1×10^-7 cubic meters.

Water droplets can be defined as the formation of small ball like structures with water due to the action of surface tension of liquid.

To convert cubic centimetres to cubic meters the following is carried out;

1 cubic meter = 1,000,000 cubic centimetres.

X cubic meters = 0.1 cubic centimetres

Make X cubic centimetres the subject of formula;

The balance (future value) in Malik's account after 2 years of investing $7,550 at 1.95% compounded annually is $7,847.32.

The future value is the compounded present value of an investment or periodic deposit.

The future value can be determined using the FV formula, FV table, or an online finance calculator as below.

N (# of periods) = 2 years

I/Y (Interest per year) = 1.95%

PV (Present Value) = $7,550

PMT (Periodic Payment) = $0

Results:

Future Value (FV) = $7,847.32

Total Interest = $297.32

Thus, Malik's account balance (future value) after 2 years will be $7,847.32.

The units price are:

Then brand A is the better option.

If you know that a set of N items has a price P, then the unit price is given by the quotient between the price and the number of items that you get, N.

For Brand A, we know that there are 25 spoons for $1.99, then in this case the unit price is:

a = $1.99/25 = $0.0796

For Brand B the set has 42 spoons for $3.89, then the unit price is:

b = $3.89/42 = $0.0926

So we can see that Brand A has a lower unit price, meaning that is a better option.

Answer:

I think it is $10.50 per hour. Hope this helps!!

By solving a system of equations we will see that the exponential function is:

g(x) = 122.347*(0.589)^x

We know that our function is of the form:

g(x) = a*(b)^x

We also know that g(3)=25 and g(7)=3, then we can write:

a*(b)^3 = 25

a*(b)^7 = 3

So we have a little system of equations.

Taking the quotient between the second and first equations we get:

(a*(b)^7)/(a*(b)^3) = 3/25

b^4 = 3/25

b = (3/25)^(1/4) = 0.589

Replacing that in the first equation we get:

a*(b)^3 = 25

a*(0.589)^3 = 25

a = 25/(0.589)^3 = 122.347

The exponential function is:

g(x) = 122.347*(0.589)^x

Answer:

x = -1

Step-by-step explanation:

6x +5 = -7x - 8

6x +7x = -8 -5

13x = -13

13/13 x = -13/13

x = -1

The measurement of each angle represented in terms of x is 156°

Here given the two angles : (13x-26)° and (9x+30)°.

We have to find each angle measurement.

From the given figure, it is clear that two angles are just vertically opposite angles.

So , we know that vertically angles are equal

So to find angles , we have to find x.

13x - 26 = 9x + 30

13x - 9x = 30 + 26

4x = 56

x = 56 / 4

x = 14

So the value of x = 14

Then we have to substitute the value of x in any of the given measurement.

By substituting x in (13x - 26)°

13 x 14 - 26

182 - 26

= 156

Similarly by substituting x in (9x + 30) °

9 x 14 + 30

= 126 + 30

= 156°

Therefore, the measurement  of each angle is 156°.

This is because it is of the form y = kx where k = 8/7 is the constant of proportionality.

Answer: The correct answer is C) 30 gallons of gas

Step-by-step explanation:

Storage Tank Volume = 1680 Gallons

25 cars x 24 gallons = 600 gallons

35 trucks x 30 gallons = 1,050 gallons

Total gallons used = 1,050 + 600 = 1,650

Remaining gas = 1,680 - 1,650 = 30 gallons

Option C: 30 gallons of gas

Please remember to vote the answer as Brainliest if I earned it!

Answer:

C) 30 gallons of gas

Step-by-step explanation:

Total gallons of gas used by the cars:

⇒ 25 × 24 = 600 gallons

Total gallons of gas used by the trucks:

⇒ 35 × 30 = 1050 gallons

Total gallons of gas used by the cars and trucks:

⇒ 600 + 1050 = 1650 gallons

If the storage tank contained 1680 gallons of gas, then the number of gallons of gas left in the tank after the cars and trucks have filled their tanks is:

⇒ 1680 - 1650 = 30 gallons

Answer: x=-1 & y=2

Step-by-step explanation:

x = -3y+5

^^^substitute this equation into x in the second equation

(-3y+5)+9 = 4y

-3y+14 = 4y

Add +3y on both sides

14 = 4y+3y

14 = 7y

divide both sides by 7

y = 2

substitute y into either equation (I'm doing the first one)

x = -3(2)+5

The largest possible volume V is  4000[tex]cm^3[/tex]

Given,

Volume of a box = length × breadth × height= l× b× h

In this case the box have a square base. i.e.,  l = b

Volume V = [tex]l^2[/tex] × h

We using the formula of Surface area

The surface area of a square box

S = 2(lb +lh+ bh)

S = 2([tex]l^2[/tex] + lh + lh) since l=b

S = 2([tex]l^2[/tex] + 2lh)

Also, Given that the box is open top.

S = [tex]l^2[/tex] +4lh

And Surface Area of the box is 1200cm^2

1200 = [tex]l^2[/tex] + 4lh ....1

Making h the subject of formula

h = (1200 - [tex]l^2[/tex])/4l .....2

Volume is given as

V = [tex]l^2[/tex] × h

V = [tex]l^2[/tex] ×(1200 - [tex]l^2[/tex])/4l

V = (1200l - [tex]l^3[/tex])/4

the maximum point is at dV/dl = 0

dV/dl = (1200 - [tex]31^2[/tex])/4

dV/dl = (1200 - [tex]31^2[/tex])/4 = 0

[tex]31^2[/tex]= 1200

[tex]l^2[/tex] = 1200/3 = 400

l = √400

I = 20cm

Since,

h = (1200 - [tex]l^2[/tex])/4l

h = (1200 - [tex]20^2[/tex])/4×20

h = (800)/80

h = 10cm

Hence, The largest possible volume V is ;

V = [tex]l^2[/tex] × h

The rocket reaches its maximum height of 88 feet at 2.25 seconds after launch

The time

The function is given as

h(t) = -16t² + 72t + 7

To start with, we need to differentiate the function

h'(t) = -32t + 72

Next, we set the differentiated function to 0

-32t + 72 = 0

Next, we solve for the variable t

t = 2.25

This means that the time is 2.25 seconds

The maximum height

Recall that we have the value of t to be:

t = 2.25

Also, we have the equation to be

h(t) = -16t² + 72t + 7

So, we have

h(2.25) = -16(2.25)² + 72(2.25) + 7

Solve the expressions

h(2.25) = 88

The number of weeks that it'll take Maru to fully pay off $43000 is 571.4 weeks.

From the information, Maru makes an initial down payment of $3000 then repays $70 per week and the total amount is $43000.

Let the number of weeks be represented as w.

This will be illustrated as:

3000 + (70 × w) = 43000

3000 + 70w = 43000

Collect like terms

70w = 43000 - 3000

Step-by-step explanation:

The variable g has its value to be -4 on the given coordinate point

From the question, the points are given as

(g, -1) and (2, 5)

Rewrite the above points properly

So, we have the following ordered pairs

(x, y) = (g, -1) and (2, 5)

The slope of the line is given as

Slope = 3/2

The slope of the line is then calculated using the following slope equation

Slope = (y₂ - y₁)/(x₂ - x₁)

Where

(x, y) = (g, -1) and (2, 5)

Substitute the known values in the above equation

So, we have the following equation

3/2 = (5 + 1)/(2 - g)

Evaluate the sum in the equation

This gives

3/2 = 6/2 - g

Cross multiply

So, we have

2(2 - g) = 12
