Answer:

x = 9

Step-by-step explanation:

To find the value of x to make the 2 expressions equal, then equate them, that is

3x - 6 = 2x + 3 ( subtract 2x from both sides )

x - 6 = 3 ( add 6 to both sides )

x = 9

Then

3x - 6 = 3(9) - 6 = 27 - 6 = 21 and 2x + 3 = 2(9) + 3 = 18 + 3 = 21

There are different ways through which you can earn money through a share, either from Exxon or from any other company. These are:

-Through obtaining profits by collecting dividends, which are sums of money that each company pays to shareholders as a way to distribute profits.

-Through the maintenance of the share in the investment portfolio, when it rises in value, it will also cause the shareholder's wealth to rise.

-Through the short investment, seeking to earn money through the "bet" for the fall in the value of the share.

Answer:

Step-by-step explanation:

plug it in

(4*3-4)+(-10+4)

8+(-6) = 2

Answer: (4x-y) + (-10 + y) = 2 , if x=3 and y=4

Step-by-step explanation:

We can substitute the known values for x and y

(4(3) - 4) + (-10 + 4) = 12 - 4 -10 +4 = 2

The line passing through the point (4, -6) and perpendicular to the line y=1/4x+4 has an equation in point-slope form of y + 6 = -4(x - 4) and in slope-intercept form, it is y = -4x + 10.

In Mathematics, lines that are perpendicular have slopes that are negative reciprocals of each other. This means if one line has a slope of m, the line perpendicular to it will have a slope of -1/m. The given line has a slope of 1/4, so the line perpendicular to it will have a slope of -4 (negative reciprocal of 1/4).

The point-slope form of a line is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line. Thus, the equation of a line passing through the point (4, -6) with a slope of -4 can be expressed as y - (-6) = -4(x - 4), which simplifies to y + 6 = -4x + 16 or y = -4x + 10.

The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept. Therefore, based on our previous findings, the equation of the line in slope-intercept form is y = -4x + 10.

Answer:

0.225 L of milk, would be required if she uses 450 m L of water.

Step-by-step explanation:

Here, to make the shake, ingredients used by Dina are:

40 m L of chocolate syrup,

200 m L of milk, and 400 m L of water.

So, here Amount of water used = 2 x ( Amount of Milk used)  .......  (1)

Now,again the amount of water used by Dona = 450 m L

Let us assume the milk used by her  = k m L

⇒ 450 m L = 2 x ( k m L)     ( from (1))

or, 450 = 2  k

⇒  k    = 450/2  = 225

⇒   k   = 225 m L

Also, 1 m L = 0.001 L

So, 225 m L = 225 x  0.001  = 0.225 L

⇒   k   = 0.225  L

Hence, 0.225 L of milk, would be required if she uses 450 m L of water.

Dona would need 0.225 liters of milk when using 450 mL of water for her chocolate shake.

To find out how much milk would be required if 450 mL of water is used, we should first look at the ratio of water to milk in the original recipe. Dona used 400 mL of water for 200 mL of milk, which is a 2:1 ratio of water to milk. If she uses 450 mL of water, maintaining the same ratio, we would calculate the amount of milk required as follows:

Determine the proportion of milk to water used originally: 200 mL milk / 400 mL water = 1/2.

Using the proportion, calculate the new amount of milk for 450 mL water: (1/2) * 450 mL = 225 mL.

Convert the milk from milliliters to liters: To do this, we know that 1 liter is equivalent to 1,000 milliliters. Therefore, we divide 225 mL by 1,000 to convert to liters.

225 mL / 1,000 = 0.225 liters of milk is needed.

4.5/25 = (4.5×4)/(25×4) = 18/100 = 0.18.

:)

The answer to the division question 'What is 4.5 divided by 0.25' is 18, because a whole (1) can be expressed as 4 parts in 0.25 decimal representation, and when multiplied by 4.5 it gives 18 parts.

The student has asked: 'What is 4.5 divided by .25'. This is a division question within the subject of Mathematics.

To solve this, you will need to divide 4.5 by 0.25. If we perform this division, we get 18. Therefore, 4.5 divided by 0.25 equals 18.

This is because if take a whole (which is 1 in decimal and represents 4 parts in 0.25 decimal representation), and we multiply it by 4.5, we get 18 parts of 0.25.

Final answer:

The density of the wooden dowel can be determined using the principle of buoyancy to calculate the volume of the submerged part and the total volume of the dowel which, when combined with the mass of the displaced water, provides the density of the dowel.

Explanation:

To determine the density of the wooden dowel based on its flotation characteristics, you can use the principle of buoyancy, which states that the buoyant force exerted on a submerged object equals the weight of the fluid displaced by that object. Since the dowel floats in water, the weight of the displaced water equals the weight of the dowel.

First, calculate the volume of the submerged part of the dowel: The dowel has a diameter of 1.20 cm, and the submerged height is the total diameter minus the portion above water, which is 1.20 cm - 0.400 cm = 0.800 cm. The volume (V) of the submerged cylinder is V = πr^2h, where r is the radius (half the diameter) and h is the submerged height. Plugging in values, V = π(0.6 cm)^2(0.8 cm).

Second, calculate the mass (m) of the dowel using the density (ρ) of water (1 g/cm^3) and the volume of water displaced which equals the volume of the submerged part of the dowel: m = ρ_water * V_submerged.

Finally, to find the density of the dowel, divide the mass of the dowel by the total volume of the dowel. The total volume is the same formula V = πr^2h, but with h being the full diameter of the dowel since it's cylindrical. The density of the dowel is ρ_dowel = m / V_total.

Using these steps, you can calculate the density of the dowel.

Answer:

t = t₀ - 3n

Step-by-step explanation:

Let t be the temperature and t₀ be the initial temperature of the day

Let n be the number of hours after the initial temperature ( t₀) was registered

Let -3 be the constant of change of temperature ( In 4 hours it went down 12 degrees)

Now, let's write down the expression that shows the temperature change each hour, this way:

t = t₀ - 3n

After 2 hours

t = t₀ - 3 * 2 = t₀ - 6

After 5 hours

t = t₀ - 3 * 5 = t₀ - 15

After 3 hours and 30 minutes

t = t₀ - 3 * 3.5 = t₀ - 10.5

Daniel bought 2 spoons and 5 forks by using a system of equations and solving for the number of each utensil.

The question involves determining how many spoons and forks Daniel bought given that spoons cost $5, forks cost $6, he bought a total of 7 utensils, and spent $40. To solve this, we can use a system of equations where s represents the number of spoons and f represents the number of forks.

The first equation represents the total number of utensils bought:

s + f = 7

The second equation represents the total amount spent:

5s + 6f = 40

To find the values of s and f, we can solve the system of equations. Subtracting the first equation from the second equation (multiplied by 5) gives:

5s + 6f = 40
-(5s + 5f = 35)
------------------
f = 5

Substituting f = 5 into s + f = 7, we get s = 2. Hence, Daniel bought 2 spoons and 5 forks.

The unit rate is 60 miles per hour and the driver will reach before time with the calculated constant speed

Step-by-step explanation:

Given

Distance = d = 45 miles

Time = t = 3/4 hour

The unit rate is defined as the distance per unit time. In this case, the unit rate can also be called speed.

So,

[tex]s = \frac{d}{t}\\s = \frac{45}{\frac{3}{4}}\\s = 45 * \frac{4}{3}\\s = 60\ miles\ per\ hour[/tex]

Using this unit rate we can see if the car can travel 65 miles in 1.25 hours or not

Given

Distance = d1 = 65 miles

Speed = s = 60 miles per hour

Putting the values in the formula for speed

[tex]s = \frac{d_1}{t_1}\\60 = \frac{65}{t_1}\\t_1 = \frac{65}{60}\\t_1 = 1.08\ hours[/tex]

As we can see that 1.08 is less than 1.25 so the driver will reach the meeting before time if he drives on a constant speed of 60 miles per hour

Hence,

The unit rate is 60 miles per hour and the driver will reach before time with the calculated constant speed
