Answer:

The slope of this line is 5/3. Or, 1 2/3. The equation would be y = 5/3x

Step-by-step explanation:

You are in luck my friend!

To find the slope of a line on a graph, you need to find the rise over run. You need to pick two definite points on a graph. An intersection whereyou can clearly tell the value. For example 1,1 and -4,-4. Then use your finger and trace how many units up you have to go, and then how many units across. (This is a very common topic so if you need further help just look up rise over run. This fact will put you ahead, do you see how the line intersects between the 2 and the 3 in the y axis? This is called the y intersect, you will see it added to the slope so if the equation is y = 5/3x it would be written as y = 5/3x + 2.5 because that is where the line intersects with the y axis.) Back to slope, remember that the formula is always rise/run. Later, you will find to points and use a slope formula. y2-y1/x2-x1.

Step-by-step explanation:

Answer:

452.4 square feet

Finding the diameter:

Since there are 3 centimeters for every 4 feet, we need to divide 18 by 3

18 ÷ 3 = 6 which means the ratio is scaled up by 6 so we multiply 4 by 6

4 · 6 = 24 that means that the diameter of the base of the fountain is 24 feet

Finding the area:

Since the area of a circle is πr² we need to divide the diameter by 2 to get the radius(r)

24 ÷ 2 = 12 now we need to square 12 (which is multiplying it to itself ex. 5² is 5 · 5)

12 · 12 = 144 now we multiply it by π

π · 144 ≈ 452.38934 lastly we round it

452.4 square feet

Answer:

Step-by-step explanation:

Using the sine ration on the left, right triangle

sin35° = \(\frac{opposite}{hypotenuse}\) = \(\frac{a}{8.6}\) ( multiply both sides by 8.6 )

8.6 × sin35° = a , thus

a ≈ 4.93 cm

a + b = 15.7, so

4.93 + b = 15.7 ( subtract 4.93 from both sides )

b = 10.77

-------------------------------------------------------------

Using the cosine ratio on the left, right triangle

cos35° = \(\frac{adjacent}{hypotenuse}\) = \(\frac{y}{8.6}\) ( multiply both sides by 8.6 )

8.6 × cos35° = y , so

y ≈ 7.04 cm

Using Pythagoras' identity on the right, right triangle

c² = b² + y² = (10.77)² + (7.04)² = 115.99 + 49.56 = 165.55

Take the square root of both sides )

c = \(\sqrt{165.55}\) ≈ 12.87 cm

Answer:

Mean = 33.7

Median = 34.5

Mode = 34

Range = 33

After adding 26....

mean decreases by 0.7

median decreases by 0.5

mode is 34

range is 33

Step-by-step explanation:

mean = sum of all the data values/number of data values

= (18 + 19 + 20  + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7

To find median arrange the values in increasing order, find the mid value

If the number of data points is even, find the average of the mid 2 data values

Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51

Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5

The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once

Mode = 34

The range is highest - lowest = 51 - 18 = 33

After we add 26, we get the following data set arranged

18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51

we can calculate the stats using the same technique as above

We get the following values

mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33  

median = 34

mode = 34

range = 51-18 = 33

To find the decrease in mean and median subtract from the first set of values

The ten expressions that requires BEMAS solution are:  + 3 x 2 - 5 ÷ 1

Now, let's solve each of these expressions using the BEDMAS rule:

(1) 4 + 3 x 2 - 5 ÷ 1 = 4 + 6 - 5 = 5

(2) 2 x 3 + 8 ÷ 4 - 1 = 6 + 2 - 1 = 7

(3) 10 ÷ 2 + 5 - 3 x 2 = 5 + 5 - 6 = 4

(4) 7 - 4 x 3 + 2 ÷ 1 = 7 - 12 + 2 = -3

(5) 5 x 2 + 4 - 6 ÷ 3 = 10 + 4 - 2 = 12

(6) 3 ÷ 1 + 4 x 2 - 7 = 3 + 8 - 7 = 4

(7) 6 - 2 ÷ 1 + 5 x 3 = 6 - 2 + 15 = 19

(8) 9 + 1 x 2 - 4 ÷ 2 = 9 + 2 - 2 = 9

(9) 12 ÷ 3 - 1 x 5 + 2 = 4 - 5 + 2 = 1

(10) 8 - 6 ÷ 2 + 3 x 1 = 8 - 3 + 3 = 8

Answer: A 1/5

Step-by-step explanation:

Probability of getting blue marble, red marble, white marble, and purple marble are 1/4, 2/5, 1/5 and 3/20 respectively.

What is probability ?

Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.

Given that,

Number of blue marbles = 5,

Number of red marbles = 8,

Number of white marbles = 4,

And number of purple marbles = 3.

Total number of marbles = 5 + 8 + 4 + 3 = 20

Probability of getting blue marble = number of blue marbles/total number of marbles

=5/20=1/4

Apply same formula,

Probability of getting red marble= 8/20 = 2/5

Probability of getting white marble = 4/20 = 1/5

Probability of getting purple marble = 3/20

A 1/5

Answer:

102

Step-by-step explanation:

Since 2 + 8 = 10, then the cube root of 5x+2 = 8

Since 8×8×8=512, then 5x+2=512

5x=510, so x=102

Answer:

C) 102

Step-by-step explanation:

Hello !

2 + ∛(5x + 2) = 10

∛(5x + 2) = 10 - 2

∛(5x + 2) = 8

(∛(5x + 2))³ = 8³

5x + 2 = 512

5x = 512 - 2

5x = 510

x = 510 : 5

x = 102

Good luck !

Answer:

Step-by-step explanation:

reason 1:

opening of brackets to solve the expression

reason 2:

in multiplication order is followed i.e. the number always lead the variable in the expression

reason 3:

for clarification brackets are added to multiply like terms i.e. numbers with numbers and variable with the variable

reason 4:

the solved and simplified expression is delivered as a result

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500
