Answer:

Area of a parallelogram would be 13.46

Step-by-step explanation:

Since area of a parallelogram is represented by the formula

Area = [tex]\frac{1}{2}[/tex] ([tex](D_{1}*D_{2})[/tex]

Where [tex]D_{1}[/tex] and [tex]D_{2}[/tex] are two diagonals of the given parallelograms.

In the given figure [tex]D_{1}=AC[/tex] and [tex]D_{2}[/tex] = BD

We will find the length of [tex]D_{1}[/tex] and [tex]D_{2}[/tex] first

Since points A and C are (3,6) and (5,1)

So distance AC = [tex]\sqrt{(6-1)^{2}+(3-5)^{2}  }[/tex]

= [tex]\sqrt{5^{2}+(-2)^{2}}[/tex]

= [tex]\sqrt{25+4}=\sqrt{29}[/tex]

Since B and D are the points (6, 5) and (2, 2)

So length of BD = [tex]\sqrt{(6-2)^{2}+(5-2)^{2}}[/tex]

BD = [tex]\sqrt{4^{2}+3^{2}}=\sqrt{25}=5[/tex]

Now we will put these values in the formula

Area of parallelogram = [tex]\frac{1}{2}(\sqrt{29})(5)[/tex]

= [tex]\frac{5}{2}[/tex] × [tex]\sqrt{29}[/tex]

= (2.5) (5.385)

= 13.46

Answer:

68

Step-by-step explanation:

Since this is an isosceles triangle the bottom 2 angles are equal.  So both bottom angles are 56 degrees.  The three angles of a triangle add to 180 degrees.

56+ 56+ x = 180

Combine like terms

112 +x =180

Subtract 112 from each side

112-112+x = 180-112

x =68

Because this is a parallelogram, we know that the diagonals bisect. This means that AO = DO, and CO = BO

It doesn't matter which two segments we use, but I'm going to use CO = BO for this one.

3x - 7 = x - 1

2x = 6

Option B. is the answer.

Answer: d

Step-by-step explanation:

Answer:

y= 1/2 x +11/2

Step-by-step explanation:

To find the slope

m = (y2-y1)/(x2-x1)

  = (8-5)/(5--1)

  = 3/(5+1)

  = 3/6

  = 1/2

Using point slope form of a line

y-y1 = m(x-x1)

y-5 = 1/2(x--1)

y-5 = 1/2(x+1)

Distribute

y-5 = 1/2x +1/2

Add 5 to each side

y = 1/2x + 1/2 + 5

Change 5 to 10/2

y = 1/2x + 1/2 + 10/2

y = 1/2x + 11/2

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0) or (0,y)

To find the slope, you can use the slope formula and plug in the two points:

(-1,5) = (x₁ , y₁)

(5,8) = (x₂ , y₂)

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]m=\frac{8-5}{5-(-1)}[/tex]

[tex]m=\frac{8-5}{5+1} =\frac{3}{6} =\frac{1}{2}[/tex]

y = 1/2x + b

To find "b", plug in either of the points into the equation:

(5,8)

y = 1/2x + b

8 = 1/2(5) + b

8 = 5/2 + b      Subtract 5/2 on both sides

8 - 5/2 = b         Make the denominators the same in order to subtract them

16/2 - 5/2 = b

11/2 = b

[tex]y = \frac{1}{2}x+\frac{11}{2}[/tex]    

The 3rd option is your answer

The correct option is c. The total is calculated incorrectly.

When making a deposit, it is crucial that the total amount being deposited is calculated correctly on the deposit ticket. This total amount should match the sum of the cash and checks being deposited. If there is a discrepancy between the subtotal of the individual amounts and the total, the deposit ticket will not be accepted because it does not accurately reflect the amount of money being handled.

Here's the logic behind why the other options are not the primary issue:

a. The sub total is calculated incorrectly: While this is a potential error, the primary concern for the teller would be the total amount being deposited. The subtotal informs the depositor and the bank of the breakdown of the deposit, but the total is what ultimately needs to be correct for the deposit to be processed accurately.

b. Alissa forgot to sign the deposit ticket for less cash back: While a signature is important for verification purposes, especially if cash back is requested, the absence of a signature would typically result in the teller asking for a signature rather than outright rejection of the deposit ticket. The calculation of the total deposit amount is a more fundamental error that must be corrected before the deposit can be accepted.

d. Alissa forgot to date the deposit ticket: The date on a deposit ticket is important for record-keeping purposes. However, forgetting to date the deposit ticket is usually a minor issue that can be resolved quickly at the teller's window. It would not typically prevent the deposit from being accepted, assuming the total deposit amount is correct.

In summary, the teller's refusal to accept the deposit ticket in its current form most likely stems from an incorrect total calculation, as this directly affects the accuracy of the deposit transaction. Alissa will need to ensure that the total on the deposit ticket correctly reflects the sum of the cash and checks she is depositing. Once the total is corrected, the deposit ticket should be accepted by the teller.

If there are 4 yellow pencils for each blue one, then this is the answer. If not then comment and tell me.

Blue   Yellow

5        20

7        28

9        36

11        44

13       52

The required number of yellow and blue pencils are 44 and 11 respectively.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
As Shawan has 4 yellow pencils for every blue pencil,
Let the number of blue pencils be b,
Now,
Yellow pencil (y) = 4 × b
Now,
put b = 5,7,9,11, or 13
So y = 20, 28, 36, 44, or 52

Now,
b + y  = 55
when b = 11 and y = 44 sums of the pencil would be 55.

Thus, the required number of yellow and blue pencils are 44 and 11 respectively.

Answer:

Proportion states that the two ratio or fractions are equal.

Given the statement: One grain of sand approximately weighs 7 * 10^{-5} g.

To find how many grains of sand are there in 6300 kg of sand.

Let x be the number of grains of sand in 6300 kg of sand.

Using conversion :

1 kg = 1000 g

6300 kg = 6300000 g

Then, by using proportion method, we have;

[tex]\frac{1}{7\times 10^{-5}}= \frac{x}{6300000}[/tex]

[tex]\frac{10^5}{7} = \frac{x}{6300000}[/tex]

By cross multiply we get;

[tex]6300000 \times 10^5 = 7x[/tex]

or

[tex]63 \times 10^5 \times 10^5 = 7x[/tex]

[tex]63 \times 10^{5+5} = 7x[/tex]  [using [tex]x^a \cdot x^b = x^{a+b}[/tex]]

[tex]63 \times 10^{10} = 7x[/tex]

Divide both sides by 7 we get;

[tex]x = \frac{63 \times 10^{10}}{7} = 9 \times 10^{10}[/tex]

Standard form is a way of of writing down very large or very small numbers easily.

Therefore, [tex]9 \times 10^{10}[/tex] grains of sand are there in 6300 kg of sand.

Answer:the value of y is 44

Step-by-step explanation:

Multiply the probability by the cost of the accident:

14,886.05 x 0.071 = 1056.91

Now add the overhead cost:

1056.91 + 110 = 1166.91

The closest answer to this is number D.

Answer:

D. $1165.49

Step-by-step explanation:

We have that the probability of a driver getting into an accident = 7.1% i.e. 0.071.

Now, the average cost of an accident = $14,886.05

Then, the expected cost of an accident =  $14,886.05 × 0.071 = $1056.91

As, the overhead cost for insurance = $110

Therefore, the driver's insurance premium = $1056.91 + $110 = $1166.91

Since, the closest option to $1166.91 is option D.

Hence, the driver's insurance premium will be $1165.49.

Answer:

x = 2

Step-by-step explanation:

check by substituting each given value of x into the function

x = 0 ⇒ y = [tex]\frac{3}{4}[/tex] × 0² = 0

hence (0, 0) is correct

x = 2 ⇒ y = [tex]\frac{3}{4}[/tex] × 4 = 3

hence (2, 4 ) is incorrect

x = 3 ⇒ y = [tex]\frac{3}{4}[/tex] × 9 = 6 [tex]\frac{3}{4}[/tex]

hence (3, 6 [tex]\frac{3}{4}[/tex]) is correct

x = 5 ⇒ y = [tex]\frac{3}{4}[/tex] × 25 = 18 [tex]\frac{3}{4}[/tex]

hence (5, 18 [tex]\frac{3}{4}[/tex]) is correct

Answer:

y = [tex]\frac{1}{2}x + \frac{29}{4}[/tex]

Step-by-step explanation:

First, we need to rearrange the equation to make it y = mx + c

4x - y = 3

y + 3 = 4x

y = 4x -3

So the slope of the line is 4.

The slope of a line perpendicular to an equation is:

[tex]\frac{-1}{gradient}[/tex]

So the slope of the perpendicular line is:

[tex]\frac{-1}{4}[/tex] = -0.25

Now to find the equation of a line you can use the following equation:

y - y₁ = m(x - x₁)

Where y₁ is the y-coordinate, x₁ is the x-coordinate and m is the gradient. Plug the values in:

y₁ = 6

x₁ = -5

m = [tex]\frac{-1}{4}[/tex]

y - 6 = [tex]\frac{-1}{4}[/tex](x - - 5)

To get rid of the fraction we need to multiply the whole equation by 4:

4y - 24 = -1(x - - 5)

The two negatives cancel out:

4y - 24 = -1(x + 5)

Multiply the brackets out:

4y - 24 = -x + 5

Now, to rearrange the formula back into y = mx + c

Move the -24 over to the other side making it a +24:

4y = 2x + 5 + 24

4y = 2x + 29

Divide everything by 4:

y = [tex]\frac{2}{4}x + \frac{29}{4}[/tex]

y = [tex]\frac{1}{2}x + \frac{29}{4}[/tex]

Answer:  [tex]\frac{x^2}{10} = -\frac{y^2}{18}[/tex]

Step-by-step explanation:

Since, The degenerate form of an ellipse is always a point.

Thus, the equation that shows only a point will be our answer.

Since [tex]9x^2 + 4y^2 = 1[/tex] is the equation of an ellipse,

Thus, It can not be a point.

[tex]\frac{x^2}{14} + \frac{y^2}{19} =2[/tex] is not a point ( because it is an equation of ellipse)

But, when we plot [tex]\frac{x^2}{10} = -\frac{y^2}{18}[/tex]

We get only a point (0,0).

Thus, equation, [tex]\frac{x^2}{10} = -\frac{y^2}{18}[/tex] shows only one point.

Therefore, it is a generated form of ellipse.

The equation representing a degenerate ellipse would have the sum of the distances from the foci to any point on the curve as a constant.

An ellipse is a closed curve such that the sum of the distances from a point on the curve to the two foci is constant. So, the equation representing a degenerate ellipse would have the sum of the distances from the foci to any point on the curve as a constant. The correct equation is (b).
