The diagram shows an isosceles triangle. Work out the size of angle y.

A 740°
B 2540°
C 286°
D 3070°

Answer:

Present Value = $413.99

Interest rate = 4.25%

Years = 8.5 years

Future value = P(1+I)^n

Future value = $413.99*(1+0.425)^8.5

Future value = $413.99*(1.0425)^8.5

Future value = $413.99*1.4244478

Future value = $589.707144722

Future value = $589.71

The total amount to be earned as a result of the investment for 8.5 years is $589.71.

Answer:

20 inches

Step-by-step explanation:

Since there are 480 miles in total, we have to divide it by 12 so we can see how many half inches that would be.

480÷12 = 40

That would mean you can fit forty 12's in 480. Since 12 miles equals 1/2, you would multiply it by 40.

1/2 × 40 =20

This means that the distance between the cities on the map would be 20 inches.

Answer:

5050

Step-by-step explanation:

we can use the formula n(n+1)/2

Answer:

5050

Step-by-step explanation:

because n(n+1)/2 is compatible here, which is (100x101)/2, and that gives us 5050.

Using the slope concept, it is found that the boat traveled at a speed of 138 feet per minute.

The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.

At point A, we have that the vertical change is of 245 ft with an angle of 12º, hence the position in feet is given by:

[tex]\tan{12^\circ} = \frac{245}{x_A}[/tex]

[tex]x_A = \frac{245}{\tan{12^\circ}}[/tex]

[tex]x_A = 1152.6[/tex]

At point B, we have an angle of 28º, hence:

[tex]\tan{28^\circ} = \frac{245}{x_B}[/tex]

[tex]x_B = \frac{245}{\tan{28^\circ}}[/tex]

[tex]x_B = 460.7[/tex]

The distance in feet the boat traveled in 5 minutes was of:

[tex]d = x_A - x_B = 1152.6 - 460.8 = 691.8[/tex]

Velocity is distance divided by time, hence:

v = 691.8/5 = 138.

The boat traveled at a speed of 138 feet per minute.

Answer:

  A.  4 square units

Step-by-step explanation:

The area of a triangle is given by the formula ...

  A = 1/2bh

Your triangle has a base of 4 units and a height of 2 units. Its area is ...

  A = 1/2(4)(2) = 4 . . . . square units

__

The triangle dimensions are easily found from your diagram by counting grid squares. If you like, you can subtract the x-coordinates of the points on the horizontal line y=1 to find the base length: 2 -(-2) = 4. And you can subtract the y-coordinates of the points on the vertical line x=-2 to find the height: 3 -1 = 2.

The minimum payment of card u of Connie is $11.54 is greater than the minimum payment of credit cart v.

Percentage of a number is the part of the number expressed in the in every hundred. Percentage of a number is expressed with the symbol '%'.

Connie has two credit cards, u and v. The card u has a balance of $414.55 and the minimum monthly payment on card u is 2.82% of the balance. Thus, the minimum payment for card u is,

[tex]P_u=\dfrac{2.82}{100}\times414.55\\P_u=11.69[/tex]

Card v has a balance of $751.81 and the minimum monthly payment on card v is 3.09% of the total balance. Thus, the minimum payment for card v is,

[tex]P_v=\dfrac{3.09}{100}\times751.81\\P_v=23.23[/tex]

The difference between the minimum payment of both the cards is,

Thus, the minimum payment of card u of Connie is $11.54 is greater than the minimum payment of credit cart v.

Answer:

Graph (C)

Step-by-step explanation:

To find whether the graph\table represents a relationship or a function we have to analyze the input-output values given.

Graph A.

In this graph for every input value (x-value) there are two output values (y-values).

For x = -2, y = -2, 2

So the graph doesn't represent a function.

Graph B.

For every x value there are two y-values

For x = -5, y = -3, 3

So the graph doesn't represent a function.

Graph C.

For every input value there is a different y-value.

Therefore, graph represents a function.

Graph D.

In this graph for x = 3, y = 1, 2, 3, 4

For one value of x, there are four values of y.

Therefore, graph doesn't show the relationship.

Graph C has exactly one output (y-value) corresponding to each input (x-value), therefore, the graph that represents a functional relationship is: Graph C.

A functional relationship is a relationship whereby every input in the relation has exactly one possible output.

In other words, a functional relationship must have exactly one output that corresponds to each of the input values.

Thus, graph C has exactly one output (y-value) corresponding to each input (x-value), therefore, the graph that represents a functional relationship is: Graph C.

Answer:   y = (x-2)/3

This is equivalent to y = (1/3)x - 2/3

=================================================

To get this answer, we need to swap x and y in the original equation. Then solve for y to get the inverse.

y = 3x+2

x = 3y + 2 ... x and y swapped

x-2 = 3y

3y = x-2

y = (x-2)/3

y = x/3 - 2/3

y = (1/3)x - 2/3

This final equation has slope 1/3 and y intercept -2/3

Answer:

  44

Step-by-step explanation:

The relations can be written using one variable to represent Mikhail's age: m. Gabrielle's age is (m-11), so the sum of their ages is ...

  m +(m -11) = 77

  2m = 88 . . . . . . add 11

  m = 44 . . . . . . . divide by 2

Mikhail's age is 44.

__

Additional comment

Gabrielle is 33.

You could solve this using two variables:

Adding these two equations gives the one we have above:

  2m = 88

  m = 44

__

You may have noticed we are given the sum and the difference of the two ages. The older Mikhail's age is half the sum of those two numbers. The younger Gabrielle's age is half their difference: (77 -11)/2 = 33. This "half the sum, half the difference" solution is the generic solution to a "sum and difference" problem.

Gabrielle : 33

Mikhail : 44

Explanation:

Let Mikhail's age be x

And Gabrielle's age be y.

======================

Gabrielle is 11 years younger than Mikhail

y = x - 11     [ equation 1 ]

sum of their ages is 77

x + y = 77    [ equation 2 ]

Insert equation 1 into 2

x + x - 11 = 77

2x = 77 + 11

2x = 88

x = 44

Therefore, the age of Mikhail is 44

Find Gabrielle's age:

y = x - 11

y = 44 - 11

y = 33

Therefore, the age of Gabrielle is 33

Answer:

CEFA

Step-by-step explanation:

The perimeter of a rectangle is the sum of the lengths of the 4 sides. A rectangle has two lengths of equal size and two width of equal size. To find the perimeter, add the length and width and multiply by 2.

1. perimeter = 2(3x + 2 + 2x) = 2(5x + 2) = 10x + 4

2. perimeter = 2(4x + 1 + x) = 2(5x + 1) = 10x + 2

3. perimeter = 2(x + 5 + 7) = 2(x + 12) = 2x + 24

4. perimeter = 2(4x - 3 + 5) = 2(4x + 2) = 8x + 4
