Answer:

counting, whole, integers, rational, real

Step-by-step explanation:

Counting numbers are any number above 0, and all the other groups will also fall into place if a number is a coutning number. Since 120 is a counting number, it falls into all the other groups above it too.

-2 is the slope if that's what's asked ?

Answer: 90

Step-by-step explanation:

We first need to find three consecutive numbers that adds up to 267. We know that the numbers will be somewhat close to 100 because the sum needs to be past 250.

Let's try 85,86,87.

85+86+87=258

258 is very close to 267. We know that we need to increase our numbers.

Let's try 88,89,90.

88+89+90=267

88,89, and 90 added together gives us 267. The question asks for the largest integer. In 88, 89, 90, 90 is the largest integer.

Answer:

The angle of PML is 68°.

Step-by-step explanation:

Given that total angles in a straight line is 180° so we can assume that ∠LMN is 180°. In order to find ∠PML, we have to subtract :

[tex]∠PML+∠ PMO + ∠OMN = 180[/tex]

[tex]∠PML + 90 + 22 = 180[/tex]

[tex]∠PML + 112 = 180[/tex]

[tex]∠PML = 180 - 112[/tex]

[tex]∠PML = 68[/tex]

9x-2+2x-8

11x-2-8

11x-10

Let me know if this helps :)

Answer:

11x - 10

Step-by-step explanation:

because there is a plus sign between the brackets, we just assume there are no brackets at all........so it will be:

9x - 2 + 2x - 8,,,,,,,,,bring the like terms together

9x + 2x - 2 - 8 = 11x -10.

the answer has a minus sign because when working out two negative numbers, we add them but still maintain the negative sign.

NOTE: If the sign between the brackets was a minus , the sign in the second expression would have changed from -8 to +8

Answer:

Swimmer's velocity = 1.4 m/s west (Approx)

Step-by-step explanation:

Given:

Total time taken = 35 seconds

Total displacement to west = 50 meter

Find:

Swimmer's velocity

Computation:

Swimmer's velocity = Total displacement to west / Total time taken

Swimmer's velocity = 50 / 35

Swimmer's velocity = 1.428

Swimmer's velocity = 1.4 m/s west (Approx)

Answer:

approximately 1.4 m/s west

The farm uses two harvesting tools for packages that needs to be sold. So, we have to consider the rates of both harvest tools and the number of harvest by both tools. The algebraic expression is: [tex]0.95(200h) + 0.90(22000m)[/tex]

Given that

[tex]h \to[/tex] days of hand pickers word

[tex]m \to[/tex] days harvester machine is used

[tex]n_h = 200[/tex] --- pounds of hand pickers

[tex]n_m = 22000[/tex] -- pounds of harvester

[tex]r_h = 95\%[/tex] -- pack out rate of hand pickers

[tex]r_m = 90\%[/tex] -- pack out rate of harvester

The expression to estimate the amount is calculated as:

[tex]Amount = r_h \times n_h + r_m \times n_m[/tex] --- i.e. pounds of hand picker * its pack out rate + pounds of harvester * its pack out rate

So, we have:

[tex]Amount = 95\% \times 200h + 90\% \times 22000m[/tex]

Express as decimal

[tex]Amount = 0.95 \times 200h + 0.90 \times 22000m[/tex]

Rewrite as:

[tex]Amount = 0.95(200h) + 0.90(22000m)[/tex]

Hence, option (b) is correct.

Answer:

7 pounds 3 ounces

Step-by-step explanation:

There are 16 ounces in a pound. In order to convert ounces to pounds, we need to see how many 16s fit into 115 (how many full pounds can be made with 115 ounces) and add the remainder as ounces. To do this we can do long division (which gives us 7 remainder 3), or we can divide 115 by 16 (=7.1875) and convert the decimal places to ounces by multiplying 0.1875 pounds (the remainder) by 16 (as there are 16 ounces in pound) which gives us 3 ounces.

So 115 ounces is equal to 7 pounds and 3 ounces.

The baby's weight is 7 pounds and 3 ounces.

To convert ounces to pounds, we need to divide the number of ounces by the conversion factor, which is 16. There are 16 ounces in 1 pound.

Let's denote the baby's weight in ounces as W oz, the weight in pounds as W lb, and the remaining ounces as Roz.

W oz = 115 ounces

W lb = ?

R oz = ?

First, we divide the total number of ounces by 16 to find the number of pounds:

W lb = W oz / 16

= 115/ 16

= 7.1875 pounds

So, the baby weighs 7 pounds.

To determine the remaining ounces, we multiply the decimal portion of the pounds (0.1875) by 16:

R oz = 0.1875 x 6

R oz= 3 ounce

So, the baby weighs an additional 3 ounces.

Therefore, the baby's weight is 7 pounds and 3 ounces.

3x - 8 = -2; x - 6

~Substitute

3(x - 6) = -2

~Distribute left side

3x - 18 = -2

~Add 18 to both sides

3x = 16

~Divide 3 to both sides

x = 16/3

First, subtract 7y from both sides:

3x + 7y (-7y) = 27 (-7y)

3x = -7y + 27

Next, divide 3 from all terms on both sides:

A bucket of candy contains 24 Jolly Ranchers, 18 Hershey Kisses, 12 packs of Smarties, and some Starburst. The probability of reaching in and pulling out a pack of Smarties is 1/6.How many Starburst are in the bucket?

Answer:

18

Step-by-step explanation:

Give the following :

Number of jolly ranchers = 24

Number of Hershey kisses = 18

Number of smarties = 12

Number of Starburst = s

Probability of pulling out a smarties ; P(smarties) = 1/6

Probability = required outcomes / total possible outcomes

Required outcome = 12

Total possible outcomes = (24 + 18 + 12 + s) = 54 + s

P(smarties) = 12 / (54 + s)

1/6 = 12 / 54 + s

1 × (54 + s) = 12 × 6

54 + s = 72

s = 72 - 54

s = 18

Hence number of smarties = 18

Answer:

Step-by-step explanation:

The total change in elevation of the skier is its acceleration. Acceleration is the change in velocity of a body with respect to time.

Acceleration = Velocity/Time

Given velocity of the skier = 14feet/sec

Time taken = 8secs

Acceleration of the skier = 14/8

Acceleration of the skier = 1.75ft/s²

Hence the total change in elevation after 8 seconds is 1.75ft/s²
