Answer:

278.482 kilograms of water must be evaporated each hour.

Step-by-step explanation:

Initial mass of cereal is equal to the product of cereal mass-to-mass ratio and total mass flow:

[tex]\dot m_{in,c} = r_{in,c}\cdot \dot m_{in}[/tex]

Where:

[tex]\dot m_{in,c}[/tex] - Inlet cereal mass flow, measured in kilograms per hour.

[tex]r_{in,c}[/tex] - Inlet cereal mass ration, dimensionless.

[tex]\dot m_{in}[/tex] - Cereal product mass flow, measured in kilograms per hour.

If [tex]r_{in,c} = 0.57[/tex] and [tex]\dot m_{in} = 1000\,\frac{kg}{h}[/tex], then:

[tex]\dot m_{in,c} = (0.57)\cdot \left(1000\,\frac{kg}{h} \right)[/tex]

[tex]\dot m_{in,c} = 570\,\frac{kg}{h}[/tex]

The initial mass flow of water is:

[tex]\dot m_{in,w} = \dot m_{in} - \dot m_{in, c}[/tex]

[tex]\dot m_{in,w} = 1000\,\frac{kg}{h}-570\,\frac{kg}{h}[/tex]

[tex]\dot m_{in,w} = 430\,\frac{kg}{h}[/tex]

Given that final total mass flow contains only 21 % water, the final water mass flow, measured in kilograms per hour, is:

[tex]\dot m_{out} = \frac{\dot m_{out, c}}{r_{out, c}}[/tex]

([tex]\dot m _{out, c} = 570\,\frac{kg}{h}[/tex], [tex]r_{out} = 0.79[/tex])

[tex]\dot m_{out} = \frac{570\,\frac{kg}{h} }{0.79}[/tex]

[tex]\dot m_{out} =721.518\,\frac{kg}{h}[/tex]

[tex]\dot m_{out,w} = \dot m_{out} - \dot m_{out, c}[/tex]

[tex]\dot m_{out,w} = 721.518\,\frac{kg}{h}-570\,\frac{kg}{h}[/tex]

[tex]\dot m_{out,w} = 151.518\,\frac{kg}{h}[/tex]

Finally, the amount of water that must be evaporated per hour is:

[tex]\dot m_{evap} = \dot m_{in,w}-\dot m_{out,w}[/tex]

[tex]\dot m_{evap} = 430\,\frac{kg}{h} - 151.518\,\frac{kg}{h}[/tex]

[tex]\dot m_{evap} = 278.482\,\frac{kg}{h}[/tex]

278.482 kilograms of water must be evaporated each hour.

Answer:

124

Step-by-step explanation:

we are given 146 right away.

That little square means a 90 degree angle

146 + 90 = 236

360 - 236 = 124

(360 degrees is the sum of a complete circle.)

The measure of the arc (ABC) is 270 degree.

In plane geometry, an angle is a shape made up of two rays or lines with the same terminal.

Angle can be used to measure any angular rotational motion since it cannot be measured in terms of length parameters like metres or inches. Instead, it is measured as an angle in terms of degrees or radians.

As we know that the angle of complete rotation is 360°.

So, ∠ADC + ∠ABC = 360

We know ∠ADC = 90°

Then, ∠ABC = 360° - 90°

∠ABC = 270°

Complete Question: In the diagram below, <DAB and <DAC are adjacent angles. If m<DAC = 25°, what is m<DAB in degrees? What is m<BAC in degrees?

Answer:

m<DAB = 80°

m<BAC = 105°

Step-by-step explanation:

Generate an equation that will help you find the value of x.

Since m<DAC = 25°, therefore, x - 20 = 25°

Use this equation to find x

x - 20 = 25

Add 20 to both sides of the equation

x - 20 + 20 = 25 + 20

x = 45

m<DAB = 2x - 10

Plug in the value of x

m<DAB = 2(45) - 10 = 90 - 10 = 80°

m<BAC = m<DAC + m<DAB

m<BAC = 25 + 80 = 105°

Hello there! :D

Today we're gonna learn some math, whoopie!

Alright, so we want to know how many 2/3 cups can go into 9 cups!

Firstly, I want to turn 9 cups into a fraction with the denominator of 3.

Let me do it all fancy for you:

[tex]9=\frac{x}{3}[/tex]

We know we want the denominator to be three, now we just need to do the opposite action (multiplication) to the other side to find what "x" is!

[tex]9*3= \frac{x}{3}*3[/tex]

If you have trouble understanding that step, let me know!

[tex]x=27[/tex]

Enter that into the fraction and we have:

[tex]\frac{27}{3}[/tex]

Notice that 27 is not an even number!

Now, we can the numerator of 27/3s and divide it by the numerator of 2/3s.

[tex]27/2=13.5[/tex]

This is not a whole answer, but the question is asking how many 2/3 cups can go into nine cups. Half of a 2/3 cup does not equal a 2/3 cup, so the answer would be 13 cups.

I hope this helps you can you have a wonderful day,

Kai xx

The number of 2/3 cups that can go into 9 cups is [tex]13\frac{1}{2}[/tex]

Total number of cups = 9

The number of 2/3 cups we can get from 9 cups = x

To get the number of 2/3 cups in 9 cups, we will divide 9 by 2/3

Number of 2/3 cups in 9 cups = 9 ÷ 2/3

Number of cups in 9 cups = 9  x  3/2

x   =  27/2

x  =  13.5

The number of 2/3 cups that can go into 9 cups is [tex]13\frac{1}{2}[/tex]

Answer:

I think K = 10.5

Step-by-step explanation:

First you would do the division of 2/4 which equals 0.5. Now the equation is k-0.5 = 10. If you flip the equation around it is 10 + 0.5 = k. Now you would know that k = 10.5 to check it does 10.5 - 0.5 = 10? Yes.

Answer:

250.50 - 35m = 300 - 45.25m

Step-by-step explanation:

Whenever an equation asks for when it will take x (or m in this case) amount of things or time you should know that there will be 2 different equations that have to equal each other

The equation will be 250.50 - 35m = 300 - 45.25m

The 35m is being subtracted from 250.50 because they are losing money each time they spend. This also applies to 45.25m

Also 35m and 45.25m are variables because it says they spend that much money each month. They don't specify how many months, so we have to put a variable after it.

Answer:

b) 250.5 – 35m = 300 – 45.25m

Answer:

Given f(x) = 4x and g(x) = x², (f ∘ g)(x) = 4x² and (g ∘ f)(x) = 16x², so function composition is not commutative.

Step-by-step explanation:

Option D is correct, given f(x) = 4x and g(x) = x², (fog)(x) = 4x² and (gof)(x) = 16x², so function composition is not commutative.

A relation is a function if it has only One y-value for each x-value.

Function composition is not commutative in general, meaning that (fog)(x) is not equal to (gof)(x) for all functions f and g.

Let f(x) = 4x and g(x) = x², for which function composition is not commutative.

If we compose f and g, we get:

(fog)(x) = f(g(x)) = f(x²) = 4x²

If we compose g and f, we get:

(gof)(x) = g(f(x)) = g(4x) = (4x)² = 16x²

Since (fog)(x) is not equal to (gof)(x) for all x, we can conclude that function composition is not commutative in this case.

Hence,  f(x) = 4x and g(x) = x², (fog)(x) = 4x² and (gof)(x) = 16x², so function composition is not commutative, option D is correct.

Answer:

Bill spent $988 on taxes.

Step-by-step explanation:

First, you have to find the total amount that Bill spent last month on taxes and groceries as the statement says that he spent 40% of the total amount on that:

$6,000*0.4=$2,400

Then, the statement indicates that the total amount Bill spent on taxes was 70% of the amount he spent on groceries.

Let's consider that:

x=taxes

y=groceries

With the information we can write the following:

x+y=2,400 (1)

x=0.7y (2)

You can replace 2 in 1:

0.7y+y=2,400

1.7y=2,400

y=2,400/1.7

y=1,412

Then, you can replace the value of y in 2:

x=0.7(1,412)

x=$988

According to this, Bill spent $988 on taxes.

[tex]3.14r[/tex] or [tex]\pi r[/tex]

Step-by-step explanation:

Given:

A semicircle.

To find:

Arc length of the semicircle = ?

Solution:

Formula for angle subtended by an arc on the center of circle is given as:

[tex]\theta = \dfrac{l}{r}[/tex]

where [tex]l[/tex] is the arc length and

[tex]r[/tex] is the radius of semicircle.

Angle of full circle is [tex]2\pi[/tex]

So, angle of semicircle = [tex]\pi[/tex]

Using the formula, we can see that:

[tex]l = \theta \times r[/tex]

[tex]\Rightarrow l = \pi \times r\\\\OR\\\Rightarrow l = 3.14r[/tex]

So, the answer is:

Arc Length of semicircle = [tex]3.14r[/tex] or [tex]\pi r[/tex]
