Which of these numbers is between 2 and 3 on the number line?
A. – 4
B. 3
O c.-2
D. - 5​

Answer:

3/2

Step-by-step explanation:                                                                         When selecting ratios for two variables (boys and girls) the two sides of the ratio must add up to be a factor of the total student count.  The factors of 28 include 14, 7, 4, and 2.  (1 + 1 = 2), (2 + 3 = 5), (3 + 4 = 7), and (1 + 3 = 4). 5 is the only nonfactor and cannot be the ratio of boys to girls, thus making 2 : 3 the correct answer.

Step-by-step explanation:

option d is correct

as the exponent is even so the required ans. will be positive.

hope this answer helps you dear...take care and may u have a great day ahead!

Answer:

This is a fraction equal to

30 miles ÷ 2.5 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 2.5

30 miles ÷ 2.5

2.5 hours ÷ 2.5

=

12 miles

1 hour = 12 miles hour = 12 miles per hour

______

Answer:

9 months

Step-by-step explanation:

simple interest ( I) is calculated as

I = \(\frac{PRT}{100}\)

P is the principal, R the rate of interest and T the time in years

Here I = 210, P = 3500 and R = 8, thus

210 = \(\frac{3500(8)T}{100}\) = 35 × 8T = 280T ( divide both sides by 280 )

0.75 = T

Thus T = 0.75 years = 9 months

The money was invested for 9 months

Answer:

9 months

Step-by-step explanation:

investment= 3500

interest rate= 8% PA simple

time= x years

Interest= $210

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

3/4 year= 3/4*12 month= 9 months

Step-by-step explanation:

Hello! :)

Answer:

\(\huge\boxed{751}\)

Let the smallest digit, or the units' digit, be equal to x:

Tens' digit is four more, therefore:

x + 4 represents the tens' digit.

Hundreds' digit is 2 more than the tens' digit, so:

2 + (x + 4), or x + 6 represents the hundred's digit.

These all sum up to 13, so write an expression to represent this:

x + (x + 4) + (x + 6) = 13

Combine like terms:

3x + 10 = 13

Subtract 10 from both sides:

3x = 3

Divide both sides by 3:

x = 1

Find the digits using the rules listed above:

Hundreds' digit: (1) + 6 = 7

Tenths' digit:  (1) + 4 = 5

Units' digit: 1 = 1

Therefore, the number is:

751.

1. 7b-15=5b-3

move 5b and 15

7b - 5b = -3 + 15

2b=12

b=6

2. 5c + 16.5 = 13.5 + 10c

5c=3

c=3/5

3. 20 + 3y = 10 - 2y

-5y=10

y=-2

4. 17 + 4h + 2 = 1 - 5h

19 + 4h = 1 - 5h

-9h=18

h=-2

Answer:

n(n +1) is the Total number of seats in the corner section.

Step-by-step explanation:

We are given that:

Number of seats in first row = 2

Number of seats in second row = 4

Number of seats in third row = 6

:

Number of seats in \(n^{th}\) row = \(2n\)

We can clearly see that it is an Arithmetic progression with

First term, a = 2

Common Difference, d = 2

\(n^{th}\) term, \(a_n=2n\)

To find: Total number of seats in corner sections with n rows.

i.e. Sum of n terms of above AP.

Formula for sum of n terms of an AP:

\(S_n=\dfrac{n}{2}(2a+(n-1)d)\\\)

Putting the values:

\(\Rightarrow \dfrac{n}{2} ({2 \times 2 +(n-1)2})\\\Rightarrow \dfrac{n}{2} (4 +2n-2)\\\Rightarrow \dfrac{n}{2} (2n +2)\\\Rightarrow \dfrac{n}{2} \times 2(n +1)\\\Rightarrow n(n +1)\)

n(n +1) is the Total number of seats in the corner section.

Answer:

the answer is 45 for 90 &45

Answer:

The GCF is 45

Step-by-step explanation:

Step 1:  Find the prime factorization of each number

Prime Factorization of 90:  2 * 3 * 3 * 5

Prime Factorization of 45:  3 * 3 * 5

Step 2:  Multiply the numbers that they have in common

Both numbers have 3, 3, and 5 in common.  

So we just multiply them:  3 * 3 * 5 = 45

Therefore, the GCF of 90 and 45 is:  45

Answer: The GCF is 45

Answer:

X= 72

Step-by-step explanation:

1.Find the constant proportionality (r) in y=rx

so when Y= 25 X=60 find (r)

2. Plug in information that is given to solve in the formula y=rx

y=rx

25=60r

3. Solve

divide both side by 60

r=25/60 or 0.416 with 6 repeating

4. Now you know what (r) is you can use the formula to find the value of x

30=0.416x with 6 repeating

x= 30/0.416 with 6 repeating

x=72

Hope this help you!

1. In the first problem, we need to subtract 1 from 9 since there is an addition:

9 – 1 = 8

Next, divide 8 by 2, and we get:

8 ÷ 2 = 4

This means that x = 4

Finally, check the answer by:

2(4) + 1 = 9

2. In the second problem, we need to subtract 3 from 19 since there is an addition:

19 – 3 = 16

Next, divide 16 by 4, and we get:

16 ÷ 4 = 4

This means that x = 4

Finally, check the answer by:

4(4) + 3 = 19

3. In the third problem, we need to add 2 with 7 since there is subtraction:

2 + 7 = 9

Next, divide 9 by 3, and we get:

9 ÷ 3 = 3

This means that x = 3

Finally, check the answer by:

3(3) – 2 = 7

Hope this helps :)

The spinner has a total of 6 possible outcomes, and each outcome has a different probability of occurring. To find the probability of an outcome, we divide the number of ways that outcome can occur by the total number of possible outcomes.

The possible outcomes and their frequencies are:

2 appears once

6 appears twice

8 appears three times

Therefore, the probabilities of the different outcomes are:

P(2) = 1/6 = 0.1667 or approximately 16.67%

P(5) = 0/6 = 0 or 0%

P(6) = 2/6 = 0.3333 or approximately 33.33%

P(8) = 3/6 = 0.5 or 50%

Note that the sum of all the probabilities must equal 1, since one of the outcomes must occur. In this case, 0.1667 + 0 + 0.3333 + 0.5 = 1, so we can be confident that we have calculated the probabilities correctly.

Probability is a branch of mathematics that deals with the study of random events and their outcomes. It is concerned with predicting the likelihood of a particular event occurring based on the available information.

In probability, an event is a set of outcomes, and the probability of an event is a number between 0 and 1 that indicates the likelihood of the event occurring. A probability of 0 means that the event is impossible, while a probability of 1 means that the event is certain.

In order to calculate probabilities, we need to identify the possible outcomes of an event and determine how likely each outcome is. The sum of the probabilities of all possible outcomes must always equal 1.

In the example given, the spinner has six possible outcomes, and each outcome has a different probability of occurring. By dividing the number of ways each outcome can occur by the total number of possible outcomes, we can calculate the probability of each outcome.

Probability is used in many fields, including statistics, finance, and science. It is an important tool for decision-making and risk analysis, and it can help us to make predictions about future events based on past data.

Step-by-step explanation:

Answer: He ran 50 laps.

Step-by-step explanation:

40 x 1.25 = 50

Answer:

50

Step-by-step explanation:

40/1   =   100/1

125% = 100/100   +   25/100

25% of 40 = 10

so you have the 40 laps which equal 100% and you also have 25 percent of the from the 125% and 25 percent of 40 is 10 so the answer is 40 plus 10 wich is 50

Considering area (A) of garden as 30 square feet:

30 = x(2x+7)

Now we need to expand it:

x(2x+7) = 2x^2 + 7x

2x^2 + 7x = 30

Adding this into an Algebra calculator gives us 5/2 or 2.5

So x = 2.5

To prove this:

2(2.5) + 7 = 12

14 * 2.5 = 30

Answer:

Infinity

Step-by-step explanation:

Using a calculator input: 7^832 = infinity

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.
