You want to paddle a cance across a small lake and want to know how far it is to the other side. You take
measurements on your side of the lake and make the drawing shown. What is the distance x across the lake?

Answer:

x=1

Step-by-step explanation:

Answer:

The value of a is 15.

Step-by-step explanation:

First, you have to find the total interior angles of the polygon using the formula, sum = (n-2)×180°, where n represents the number of sides :

sum = (n-2)×180°

sum = (5-2)×180°

sum = 540°

Given that the sum of the interior angle is 540° so in order to find the value of a, you have to add up all the angles in terms of a :

3a + 150 + 8a + 6a + 9a = 540

26a + 150 = 540

26a = 390

a = 390 ÷ 26

a = 15

Answer:

3x = -2 2/5 or -2.4

Step-by-step explanation:

5x + 8 = 4

5x = 4 - 8

5x = -4

x = -4/5

3x = y  If x = -4/5

3 * -4/5 = y

-12/5 = y

-2 2/5 = y

Answer:

784 red grape vines

Step-by-step explanation:

There are 28 grape vines in each of the 52 rows of a vineyard. There are 24 rows of green grapes. All other rows are red grapes. How many red grape vines are in the orchard?

In a vineyard

We have 52 rows

24 rows = Green grapes

The number of red grape rows =

52 rows - 24 rows

= 28 rows.

We are told are told: There are 28 grape vines in each of the 52 rows of a vineyard.

This means

1 row = 28 grape vines

Hence, the number of red grape vines that are in the orchard

1 row = 28 grape vines

28 rows = x grape vines

x = 28 × 28 grape vines

x = 784 red grape vines

y=2x+1

(2x) is the slope because the slope is going up the slope will be positive and the (1) is the y intercept which means where the slope crosses the vertical line

Answer:

A

Step-by-step explanation:

The equation for a graph is y=mx+b

The b is the y-intercept, or what the y-value is at x=0 (x is horizontal or left and right, y is vertical or up and down). At x=0, y is at 1, so it has to be +1.

The m is the slope, or the rise over run, which you solve by doing the equation (y2-y1)/(x2-x1).   You do this by taking one set of coordinate positions, let's say (0,1), and another, let's say (1,3).    The first set is your x1 and y1, and the second set is your x2 and y2. In this case, x1=0,y1=1,x2=1,y2=3

then do the equation. (3-1)/(1-0)   2/1=2, so the slope, or m, is 2.

Answer:

4/225

Step-by-step explanation:

To get 3 marbles that all three are different colors, we need to get a red, blue, and yellow marble (not necessarily in that order)

So we get the probability of getting each with replacement (meaning they are all out of 15) and multiply them.

The probability of getting a red is:

10/15 = 2/3

The probability of getting a blue is:

3/15 = 1/5

The probability of getting a yellow is:

2/15

So to get all 3 different colors:

2/3 * 1/5 * 2/15 = 4/225

Answer: 1 1/5

Step-by-step explanation:

Answer:

Mixed number- 1 and 1/5

Fraction- 12/10

Step-by-step explanation:

1.2 is read as 1 and 2 tenths. 1 and 2 tenths is the same as 1 and 2/10.

1 and 2/10 in simplest from is 1 and 1/5.

1 and 1/5 can also be written as 12/10.

Answer:

Step-by-step explanation:

Answer:

The value of x = 35.62

Therefore, option C) is true.

Step-by-step explanation:

Given

Ф = 58°

hypotenuse = 42

To determine:

x = ?

We know that the trigonometric ratio

sin Ф = opposite / hypotenuse

Here:

so substituting the value

sin Ф = opposite / hypotenuse

sin 58° = x / 42

x = 42 × sin 58°

  = 35.62

Thus, the value of x = 35.62

Therefore, option C) is true.

Answer:

x = 12

Step-by-step explanation:

Let a = the length of the missing side

[tex]\frac{24}{30} = \frac{44}{a}[/tex]

simplify: [tex]\frac{4}{5} = \frac{44}{a}[/tex]

use cross multiplication

4a = 220

a = 55

7x + 15 = 44 + 55

7x = 84

x = 12

Answer:

Solve equation [2] for the variable y

[2] y = 8x + 7

// Plug this in for variable y in equation [1]

[1] 4x - 5•(8x+7) = -9

[1] -36x = 26

// Solve equation [1] for the variable x

[1] 36x = - 26

[1] x = - 13/18

// By now we know this much :

x = -13/18

y = 8x+7

// Use the x value to solve for y

y = 8(-13/18)+7 = 11/9

Solution :

{x,y} = {-13/18,11/9}

Answer:

About 95% of households have an income over $54,550

Step-by-step explanation:

95% is a probability of around 0.95

So we start by calculating the z-score with a probability of 0.95

We can use the standard normal distribution table for this

the z-score is -1.645

Mathematically;

z-score = (x-mean)/SD

-1.645 = (x-71,000)/10,000

10,000 * -1.645 = x-71,000

-16450 = x - 71000

x = 71,000 - 16450

x = 54,550
