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°

Answer:

y = -1.0

Step-by-step explanation:

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operations, and =

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

First, add 4y and subtract 14 from both sides:

1y (+4y) + 14 (-14) = -4y (+4y) + 9 (-14)

1y + 4y = 9 - 14

Combine like terms:

5y = -5

Isolate the variable, y. Divide 5 from both sides:

(5y)/5 = (-5)/5

y = -5/5

y = -1

y = -1 is your answer.

Answer:   20 ounces box of cheerios is cheaper.

Step-by-step explanation:

If 10 ounce box of cheerios cost $2.80  and 20 ounce cost $5.20  then to find which is cheaper, you need to find the unit price which is the cost of an ounce.

Divide the money by the amount of ounces.

2.80 / 10 =   0.28   which is 28 cents per ounce.

5.20/20 =  0.26  which is 26 cents per ounce.

So the 20 box of cheerios is cheaper because it is 2 cents less.

Answer:

[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]

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:

Neither

Step-by-step explanation:

-2x+2y=20

First, you need to transfer the [-2x+2y=20] equation to slope intercept form. First, get the y variable on one side by subtracting -2x from the left side.

So then you have

2y= 2x+20

Then you divide the 2 from the y on BOTH side

y= x+10

Now compare the slope of both equations

y= -1/2x+10 (slope= -1/2)

y=x+10 (slope= 1)

Since the parallel slope to -1/2 is the same slope

Since the perpendicular slope to -1/2 is equal to 2/1 or 2,

Neither of them work

Step-by-step explanation:

Decimal places means the place the number is representing.

Decimal places are in ones, tens, hundreds, thousands, tens of thousands, hundreds of thousands, millions, etc

You first begin with the last number and the last number is in ones,then you move to the second number from the last which is in tens then it follows in that sequence.

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.

Answer:

No, there is no relationship

Step-by-step explanation:

Since there are no pairs of integers, I will give a general answer.

The distance between any two numbers is the absolute value of their difference.

For example we need a distance between numbers of x and y, then we just subtract them in any order and take absolute value of it:

or

There is no relationship between the sum of the numbers.

It would make sense only in case one of the numbers is zero. Then the sum or difference would be same.

Answer:

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:

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.
