How Do You get: 5(5x + 2x /5 x 8)<78

Answer:

proportional relationship does not exist.

proportional relationship does exist.

proportional relationship does not exist.

proportional relationship does exist.

Step-by-step explanation:

To establish proportionality :

For data 1:

y α x

y = kx ; k = proportionality constant

Take x = 1 ; y = 5

5 = k

k = 5

Hence, to obtain other data points :

y = 5x (if data is proportional ; if otherwise, the data isn't proportional).

Take ; x = 2

y = 5* 2 = 10

10 ≠ 9

Hence, data isn't proportional.

2.)

Data 2:

y α x

y = kx ; k = proportionality constant

Take x = hours 2 ; y = miles = 110

110 = 2k

k = 110/2

k = 55

Take ; x = 5

y = 55*5 = 275

275 = 275 (proportional relationship exist)

3.)

For the graph:

First graph isn't proportional

4 = 2k ; k = 4/2 = 2 ; k = 2

At x = 6

y = 6*2 = 12

From graph ; y = 8 at x = 6

Hence, proportional relationship does not exist.

4.)

For the 2nd graph:

4 = 2k ; k = 4/2 = 2 ; k = 2

At x = 6

y = 6*2 = 12

From graph ; y = 12 at x = 6

Hence, proportional relationship does exist.

The point of intersection of the lines, if The coordinates of the first line (0, 0) and (4, 3), and The coordinates of the second line (0, 4) and (3, 0), is (1.92, 1.44).

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Given:

The coordinates of the first line (0, 0) and (4, 3),

The coordinates of the second line (0, 4) and (3, 0),

Write the equation of the line as shown below,

The equation of the first line,

y - 0 = 3 - 0 / 4 - 0 (x - 0)

y = 3/4 x

4y = 3x

4y - 3x = 0

The equation of the second line,

y - 0 = (0 - 4) / (3 - 0)  (x - 3)

y = -4 / 3  (x - 3)

3y = -4x + 12

3y + 4x = 12

Solve these equations,

x = 1.92 and y = 1.44

Thus, they intersect at (1.92, 1.44)

Answer:

3 paperback books

Step-by-step explanation:

Let the number of paperback Kate bought be a and the number of hard books be b.

Given that she bought 5 books then

a + b = 5

Also, If Kate paid 7d dollars then

a * d + b * 2d = 7d

Divide through by d

a + 2b = 7

Hence we have 2 equations

a + b = 5

a + 2b = 7

subtract the first from the second

2b - b = 7 - 5

b = 2

since

a + b = 5

a + 2 = 5

a = 5 - 2

= 3

Recall that the number of paperback she bought is a hence this is 3

Answer:

it states to round to the tenths place for 1 which would be 1.5 because the 2 after is not 5 or above so it stays the same

it also goes for the rest that are stated in the problem

My answers:

2)76.27

3)23.494

4)8.3926

5)342.6

Answer:

You can easily round any number to any place using a simple rule. Look to the digit to the right of the digit you want to round to. If that digit is 5 or greater than 5, you round UP to the next higher digit. If the digit to the right of the digit you’re trying to round to is 4 or less, you leave the digit alone.

1. 1.528 = 1.5

2. 76.2714 = 76.27

3. 23.49382 = 23.494

4. 8.39261 = 8.926

5. 342.62984 = 342.6

Answer:

UNLIKELY

Step-by-step explanation:

Given that:

Probability of rolling a six with a six sided nuner cube = 1/6

Required outcome / Total possible outcomes

Number of 6 / total sides of number cube = 1/6

The probability value obtained shows that there is a chance of getting a six ; however it is possible at about once in every 6 rolls of the dice.

Hence getting a six isn't impossible but the chance is small. A probability of 1/6 is the smallest that can be obtained for any of each number on the dice. Hence, it could be said that the likelihood is 'UNLIKELY'

Answer:

1,680

Step-by-step explanation:

We know a hummingbird beats its wings 420 times in 30 seconds. To find the unit rate, divide 420 by 30.

420/30

42/3

14 beats/second

Now we know a hummingbird beats its wings 14 times in 1 second. Two minutes equals 120 seconds. Multiply 14 by 120 to get the answer here.

14 * 120

(14 * 12) * 10

168 * 10

1,680 beats

Answer:

1680

Step-by-step explanation:

From the table, we can see that per each 30 seconds, a mocking bird flaps its wings 420 times.

Each minute contains 60 seconds. Therefore, in order to calculate the number of times a mockingbird flaps its wings in 2 minutes, we can

60 seconds x 2 minutes = 120

Then, we can divide this number by 30 to figure out how many times we need to multiply 420 to get our answer.

120/30 = 4

Therefore,

420 x 4 = 1680

Answer:

98 degrees

Step-by-step explanation:

Since angle LON is a straight angle, that means its measure is 180 degrees. So, the two angles that make up angle LON add up to 180. You can create the following equation:

(3x + 89) + (8x + 58) = 180

Then, add like terms.

3x + 8x = 11x

89 + 58 = 147

11x + 147 = 180

Subtract 147 from both sides.

11x = 180 - 147

Add like terms.

11x = 33

Now, divide by 11 on both sides.

x = 3

Since we now have the value of x, we can plug it into the equation to find angle MON:

MON = 3x + 89

Substitute 3 for x

MON = 3(3) + 89

MON = 9 + 89

MON = 98

Answer is "c" cause it is

Find 35% of 65, since A= 35 and B= 65.  

35%=.35  

Multiply that by 65, for the percentage.

65*.35= 22.75

So, 35% of 65= 22.75

22.75 is not equal to 35.
