Answer:

B, C, G

Step-by-step explanation:

If we look at the graph, it shows that if an employee works for 5 hours, then they will earn $36.25.

We can take 36.25 and divide that by 5 to get the hourly wage.

36.25 ÷ 5 = 7.25

We now know that employees get $7.25 every hour.

Using this we can look back to the graph.

'A' says that if an employee does not work, they will earn $7.25.

We know that this is wrong because if you do not work, then you do not earn money.

Let's look at 'B'.

If employees work for one hour, they will earn $7.25

We know this is correct because we now know the hourly wage.

Let's look at 'C'

If employees work for 4 hours, then they will get a revenue of $29.

We can figure this out by using this equation.

number of hours × hourly wage = total payment

4 × 7.25 = 29

Then this means that this is correct.

Let's look at 'D'

It says that if employees work for 10 hours, they will earn $73

Let's use that same equation again.

10 × 7.25 = 72.5

Employees earn $72.5 for working 10 hours, not $73.

So, this is obviously incorrect.

Let's look at 'E'

It says that if employees work for 3.5 hours, they will get a revenue of $21.75.

3.5 × 7.25 = 25.375

Therefore, this is incorrect.

Now let's take a look at 'F'.

It says that if employees work for 7.25 hours, then they earn $1.

This is incorrect.

And lastly, 'G'.

We know that if you do not work, then you do not earn money.

Therefore, A, B and G are the correct answers.

Step-by-step explanation:

While an absolute value may be any number, the output from an absolute value expression is always greater than or equal to zero

The absolute value | x | of a real number x is defined as the non-negative value of x without regard to its sign. For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. The absolute value of a number may be thought of as its distance from zero along real number line.

The absolute value of any number is seen to be always greater than or equal to zero. Both a number and its opposite are the same distance from zero on the number line. Since they have the same distance from zero, they have the same absolute value.

The length of the field is greater than the width by the expression \((14x - 3x^2 + 2y) - (5x - 7x^2 + 7y).\)

1. The length of the field is represented by the expression \(14x - 3x^2 + 2y.\)

2. The width of the field is represented by the expression \(5x - 7x^2 + 7y\).

3. To find the difference between the length and width, we subtract the width from the length: (\(14x - 3x^2 + 2y) - (5x - 7x^2 + 7y\)).

4. Simplifying the expression, we remove the parentheses: \(14x - 3x^2 + 2y - 5x + 7x^2 - 7y.\)

5. Combining like terms, we group the \(x^2\) terms together and the x terms together: \(-3x^2 + 7x^2 + 14x - 5x + 2y - 7y.\)

6. Simplifying further, we add the coefficients of like terms:\((7x^2 - 3x^2) + (14x - 5x) + (2y - 7y).\)

7. The simplified expression becomes: \(4x^2 + 9x - 5y.\)

8. Therefore, the length of the field is greater than the width by the expression \(4x^2 + 9x - 5y.\)

Let the number be ×

Twice a number is 2×

Twice a number increase by 8 is 2×+8

hence the equivalent will be

2×+8=20

2×=12

×6

Answer:

6

Step-by-step explanation:

Let n be the unknown number.

"Twice a number" means to multiply the number by 2:  

⇒ 2n

"Increase by 8" means to add 8:

⇒ 2n + 8

"Is 20" means equals 20:

⇒ 2n + 8 = 20

Therefore, the equation is:  2n + 8 = 20

To solve, subtract 8 from both sides:

⇒ 2n + 8 - 8 = 20 - 8

⇒ 2n = 12

Divide both sides by 2:

⇒ 2n ÷ 2 = 12 ÷ 2

⇒ n = 6

Therefore, the unknown number is 6.

Step-by-step explanation:

y=mx+b is slope intercept form

to find the slope(m) you need to plug your numbers into the equation y(2)-y(1)/x(2)-x(1)

which means subtract the Y's together and the X's together and put the quotient of the Y's on top. Note that you have to choose a set of number to be the first group and the other set as the second group

so (0-6)/(-1-1) = -6/-2 = 3

3 will be your slope. plug that and a set of your numbers into the slope intercept equation

To find:-

Answer:-

We can divide the shaded circle into parts , viz a triangle and a sector . We can use the formula to find out the area of the sector which is ,

\(\longrightarrow \boxed{\rm{Area} =\dfrac{\theta}{2\pi}\times \pi r^2 }\\\)

where,

The angle substended by the traingle at the centre is 90° . In radians it would be π/2 as π rad = 180⁰ .

Now we can see that the angle substended by the arc would be ,

\(\longrightarrow \theta = 2\pi -\dfrac{\pi}{2}\\\)

\(\longrightarrow \theta = \dfrac{4\pi-\pi}{2} \\\)

\(\longrightarrow \theta =\boxed{\dfrac{3\pi}{2}} \\\)

Now substitute the respective values, in the given formula as ,

\(\longrightarrow A =\dfrac{\dfrac{3\pi}{2}}{2\pi}\times\pi (5^2) \\\)

\(\longrightarrow A = \dfrac{3}{4}\times \dfrac{22}{7}\times 25 \\\)

\(\longrightarrow \red{ A = 58.93 \ \rm{units}^2}\\\)

\(\rule{200}2\)

Finding the area of triangle:-

The given triangle is a right angled triangle with two sides as 5 . So we know that;

\(\longrightarrow \boxed{ \rm{Area}=\dfrac{1}{2} bh } \\\)

where ,

On substituting the respective values, we have;

\(\longrightarrow A = \dfrac{1}{2}\times (5\cdot 5) \\\)

\(\longrightarrow A = \dfrac{25}{2} \\\)

\(\longrightarrow \red{ A = 12.5 \rm{units}^2} \\\)

Hence the total area would be ,

\(\longrightarrow A = (58.93 + 12.5) u^2 \\\)

\(\longrightarrow A = 78.43 \ u^2 \\\)

Rounding off to nearest tenth would give us ,

\(\longrightarrow \underline{\underline{ \red{ \rm Area_{shaded \ region} = 71.4 \ units^2}}} \\\)

The actual perimeter of triangle will be 1.3m

The territory included by a triangle's sides is referred to as its area. Depending on the length of the sides and the internal angles, a triangle's area changes from one triangle to another. Square units like m2, cm2, and in2 are used to express the area of a triangle. The perimeter is the whole side covered by the all sides.

The sum of all angle of triangle = 180

Therefore, the area of the triangle ABC is approximately 18096.3 square units.

What is the area of the triangle?

To calculate the area of a triangle, use the formula area = 1/2 * base * height.

We can use Heron's formula to find the area of the triangle ABC when the lengths of its three sides are known:

\(Area = {\sqrt{(s(s-a)(s-b)(s-c))}\)

where "s" is the semiperimeter of the triangle, which is half the sum of the lengths of its three sides:

s = (a + b + c)/2

In this case, we have:

a = AB = 154

b = BC = 346

c = AC = 349

So the semiperimeter is:

s = (a + b + c)/2 = (154 + 346 + 349)/2 = 424.5

Now we can use Heron's formula to find the area of the triangle

\(Area = \sqrt{(s(s-a)(s-b)(s-c))}\\\\Area = \sqrt{(424.5(424.5-154)(424.5-346)(424.5-349))}\\\\Area= 18096.3\)

Therefore, the area of the triangle ABC is approximately 18096.3 square units.

Answer:

\(DM=12\)

Step-by-step explanation:

(Let the point where the altitude from \(D\) intersects \(AB\) be called as point \(E\).) First, let's find the area of parallelogram \(ABCD\). The area of a parallelogram is simply \(b*h=bh\), where \(b\) is the parallelogram's base and \(h\) is the parallelogram's height. If we let \(AB\) and \(DE\) be the base and height respectively, since we are already given their lengths, we know that the area of parallelogram \(ABCD\) will be \(AB*DE=15*8=120\).

Now, how does this information matter, you might ask? Well, we can take either \(AB\) or \(CB\) to be the base and either \(DE\) or \(DM\) to be the height. In this case, let's take the latter two options, as we are looking to find the length of \(DM\).

Therefore, we know that the area of parallelogram \(ABCD\) can also be found by calculating \(CB*DM\). Since we know the values of the area and \(CB\), we can write the following equation to solve for \(DM\):

\(Area = CB*DM\)

\(120=10*DM\) (Substitute \(Area=120\) and \(CB=10\) into the equation)

\(\frac{120}{10}=\frac{10*DM}{10}\) (Divide both sides of the equation by \(10\) to get rid of \(DM\)'s coefficient)

\(12=DM\) (Simplify)

\(DM=12\) (Symmetric Property of Equality)

The proportion of voters who favor stem cell research can be estimated by taking a survey and calculating (Number of voters who favor stem cell research / Total Number of voters) x 100.

Proportion of favor stem cell research = (Number of voters who favor stem cell research / Total Number of voters) x 100

In order to estimate the proportion of voters who favor stem cell research, a survey has to be taken. Suppose the survey results indicate that out of a total of 500 voters, 300 of them favor stem cell research. Then, the proportion of favor stem cell research would be calculated as follows: Proportion of favor stem cell research = (300/500) x 100 = 60%. This means that 60% of the total voters favor stem cell research.
