What is 2+2 x 2+y equaled to

Answer:

put 5 units up

In system equation method,

a) Amount of red portion = 240 ml.

b) There are 300 mL of blue potion used and 100 mL of red potion used.

c)  There is a ratio of 2 (blue potion):1 (red potion), there will be a 35% amount of magical syrup.

What is equation?

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

(a)  We can use a system equation here to solve this.

Let x=amount of red potion used

Let y=total amount of potion in solution

Then,

=>200 + x =  y

=> 0.15(200) + 0.75x = 0.25y

0.15(200) because 15% of the blue potion=.15 and there is 200mL.

0.75x because 75% of the red potion=.75 and there is x amount of it

0.25y because we want 25% of the total potion=.25 and there is y amount of it.

We can substitute for y in the second equation:

=>0.15(200) + 0.75x = 0.25(200 + x)

=> 30 + 0.75x = 50 + 0.25x

=> -20 = -0.5x

=> x = 40

Knowing that x=40, we know that y=240, meaning our answer is 240.

b.) We can again use a system for this problem

Let x=Amount of red potion

Let y=Amount of blue potion

=> x + y = 400

=> 0.3(400) = 0.15y + 0.75x

0.3(400)=30% of the 400 mL

0.15y=15% of the magic syrup

0.75x=75% of the magic syrup

We can substitute for x in this equation:

=>120 = 0.15y + 0.75(400 - y)

120 = 0.15y + 300 - 0.75y

-180 = -0.6y

y = 300, x = 100

There are 300 mL of blue potion used and 100 mL of red potion used.

c.) Let x=amount of red potion

Let y=amount of blue potion

=> 0.15x + 0.75y = 0.35(x + y)

0.35(x+y) because the total amount of the potion is x+y

=>0.15x + 0.75y = 0.35x + 0.35y

0.4y = 0.2x

2y = x

Whenever there is a ratio of 2 (blue potion):1 (red potion), there will be a 35% amount of magical syrup.

Option D : The equation that demonstrates the inverse property is D. 3/4 x 4/3= 1, which shows that the multiplication of the reciprocal of a number equals 1.

According to the multiplicative property known as the inverse property, the result of multiplying any non-zero number by its inverse or reciprocal will equal the multiplicative identity, which is 1.

The inverse property of multiplication states that for any non-zero number a, its inverse or reciprocal, when multiplied by a, will result in 1. The reciprocal of a number is the number that when multiplied by the original number results in 1.

For example, the reciprocal of 3 is 1/3 because 3 x 1/3 = 1.

Similarly, the reciprocal of 4/3 is 3/4 because (4/3) x (3/4) = 1.

So, if we multiply 3/4 by its reciprocal 4/3, we get:

(3/4) x (4/3) = (3 x 4) / (4 x 3) = 12 / 12 = 1

This shows that the product of 3/4 and 4/3 is 1, which is the multiplicative identity. Hence, this equation demonstrates the inverse property of multiplication.

Answer:

Let's assume that the width of the rectangle is 'w' meters.

According to the problem, the length of the rectangle is three times its width, so the length is:

l = 3w

The area of the rectangle is given as 300 m², so we have:

lw = 300

Substituting the value of 'l' in terms of 'w', we get:

(3w)w = 300

Simplifying the above equation, we get:

3w^2 = 300

Dividing both sides by 3, we get:

w^2 = 100

Taking the square root on both sides, we get:

w = 10

So the width of the rectangle is 10 meters.

Using the value of 'w', we can find the length of the rectangle:

l = 3w = 3(10) = 30

So the length of the rectangle is 30 meters.

The perimeter of the rectangle is given by:

P = 2(l + w)

Substituting the values of 'l' and 'w', we get:

P = 2(30 + 10) = 2(40) = 80

Therefore, the perimeter of the rectangle is 80 meters.

The life insurance policy will pay $2,256,150 to Jeff's beneficiaries per year. The solution has been obtained by using the simple interest.

What is simple interest?

A way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time is by using simple interest. The principal amount in a basic interest calculation is constant.

We are given that Jeff has to put $2,225,000 into a bank account if it ever had to make payments on the policy and the company also expects interest rates to be at 1.4% at that time.

So, from this we get,

⇒ Total Interest = $2225000 × 1.4% × 1

⇒ Total Interest = $31,150

Amount payable by company = $2225000 + $31,150

Amount payable by company = $2,256,150

Hence, the life insurance policy will pay $2,256,150 to Jeff's beneficiaries per year.

The amount of salt in the tank 10 minutes after the process begins is 9.6 pounds.

As per the given information,

a tank with a capacity of 100 gallons initially contains 50 gallons of water with 10 pounds of salt in solution. Freshwater enters at a rate of 2 gallons per minute and a well-stirred mixture is pumped out at the same rate. Compute the amount of salt (in pounds) in the tank 10 minutes after the process begins.

We know that

Amount of salt in the tank = Salt concentration x Volume of water

Amount of salt at t = 0 in the tank = 10 pounds

Volume of water at t = 0 in the tank = 50 gallons

Amount of salt at time t in the tank can be calculated by the following formula.

Amount of salt in the tank at time t = (Amount of salt at t = 0) - (Freshwater enters at rate × Salt concentration in the tank)

Now, let's calculate the amount of salt in the tank after 10 minutes.

Calculate the volume of water in the tank after 10 minutes

The rate of freshwater enters into the tank is 2 gallons per minute

So, the volume of water that entered the tank in 10 minutes = 2 × 10 = 20 gallons

Initial volume of water in the tank = 50 gallons

Volume of water in the tank after 10 minutes

= Initial volume + Freshwater enters - Freshwater pumped out

= 50 + 20 - 20

= 50 gallons

Calculate the salt concentration in the tank after 10 minutes.

Initially, the salt concentration = (Amount of salt at t = 0) / (Volume of water at t = 0) = 10/50 = 0.2 lbs/gallon

Now, the amount of salt at time t = 10 min = 10 - 2 × 0.2 = 9.6 lbs

So, the salt concentration after 10 minutes = 9.6 / 50 = 0.192 lbs/gallon

The probability of getting a red king card from the deck of cards is 1/26.

The probability formula can be used to determine the likelihood of an event by only dividing the favourable number of possibilities by the entire number of possible outcomes.

As there can never be more favourable outcomes than there are possible outcomes, the probability of an event happening can range from 0 to 1. As a result, 0 cannot represent the percentage of successful outcomes.

Given,

We have a deck of cards.

So, total no of cards = 52

Now, no of red cards = 26.

Now total no. of kings = 4.

Total no. of red kings = 2

Probability of picking a red king from the deck =

Using the sine's function in the given triangle, the value of x is 75.7 respectively.

What is the triangle?

A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon.

There are three sides and three angles in every triangle, some of which may be the same.

The angle total of a triangle will always be equal to 180°.

A quadrilateral can be divided in half from corner to corner to form a triangle because the angle total of a quadrilateral is equal to 360°.

A triangle is effectively half of a quadrilateral, therefore it makes sense that its angle measurements are also half. 180° is one-half of 360°.

So, right triangles are used to depict figures like this one, which has a hypotenuse of 85, a base of x, and a top angle of 63°.

The hypotenuse and the side that faces the angle are both present.

The sine function's opposite/hypotenuse ratio is as follows:

sin 63° = x/85

Now, solve as follows:

sin 63° = x/85

85(sin 63°) = x

75.7 = x

Therefore, using the sine's function in the given triangle, the value of x is 75.7 respectively.

The ramp will rise 16.8 inches from the ground at its highest end, when the angle of elevation is 19 degrees and the length of the fiberboard is 27 inches.

To calculate the height of the ramp at its highest end:

1. First, calculate the length of the hypotenuse of the triangle formed by the ramp, using the Pythagorean Theorem. This can be done by squaring the length of the ramp (27 inches) and the angle of elevation (19 degrees) and adding them together. The result is 750.41 inches.

2. Next, take the square root of the result from step 1. This gives us 27.45 inches, which is the length of the hypotenuse.

3. Then, subtract the length of the ramp from the length of the hypotenuse. This gives us 8.45 inches.

4. Finally, divide the result from step 3 by 2. This gives us the height of the ramp at its highest end, which is 16.8 inches.
