Answer: 2

Step-by-step explanation:

4/5 x 2 1/2 = ?

Convert 2 1/2 to 5/2

4/5 x 5/2 = ?

Do 4 x 5, and then 5 x 2.

4 x 5 = 20

5 x 2 = 10

The new fraction is now 20/10.

You can simplify the fraction to 2.

20/10=2

Answer:

2

Step-by-step explanation

4     x       5   =  20    20/10= 2

5      x      2   = 10

Option A:

Midpoint of LN = (2, 3)  

Solution:

In the given graph we can find the coordinates of L and N.  

Coordinates of L = (–2, 3)

Coordinates of N = (6, 3)

Here, [tex]x_{1}=-2, x_{2}=6, y_{1}=3, y_{2}=3[/tex]

Let us find the midpoint of the segment LN.

Midpoint formula:

[tex]$\text { Midpoint }=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)[/tex]

                [tex]\begin{aligned}&=\left(\frac{-2+6}{2}, \frac{3+3}{2}\right)\\&=\left(\frac{4}{2}, \frac{6}{2}\right)\\&=(2,3)\end{aligned}[/tex]

Midpoint of LN = (2, 3)  

Option A is the correct answer.  

Hence the coordinates of the midpoint of the line segment LN is (2, 3).

Answer:

6 inch

Step-According to the Pythagorean theorem, the square length of the rectangle + the square width of the rectangle = the square length of the diagonal. So， 8 square + ? Square = 10 square, so 64 +? = 100. 100-64 = 36, 36 is the square of 6, so the answer is 6. Hope is correct. :)

Answer:

y = 2x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2

The line crosses the y- axis at (0, - 1) ⇒ c = - 1

y = 2x - 1 ← equation of line

Answer:0.434

Step-by-step explanation:

Let's convert them to decimals:

1/25 = 0.04

4% = 0.04

0.04 = 0.04

0.4 = 0.40.

So 0.4 is NOT equivalent to the other values.

The values 1/25, 0.04, and 4% are all equivalent to each other. The value that does not match with these is 0.4.

The values given in the question are 1/25, 0.04, 4%, and 0.4. These values can be converted into the same format to compare them more easily.

Firstly, you can convert 1/25 into a decimal, which equals 0.04. Secondly, we can convert 4% into a decimal by dividing the number 4 by 100, which also equals 0.04. Lastly, when comparing these to 0.4, it becomes clear that 0.4 is not equivalent to the other numbers (0.04).

So, the value which is not equivalent to the others is 0.4.

answer:

99.43

Step-by-step explanation:

because there is a 0.57 chance something will not happen, we will fill the rest of the equation in with 100 percent subtracted by 0.57 to get 99.43. Therefore, 99.43 is the correct answer.

Final answer:

To find the probability of an event happening when the probability of it not happening is 0.57, subtract 0.57 from 1, resulting in 0.43.

Explanation:

The probability that an event will not happen is given as P(E) = 0.57. To find the probability that the event will happen, we use the formula P(A) + P(~A) = 1, where P(A) is the probability of the event happening and P(~A) is the probability of the event not happening. The probability of the event happening, therefore, is 1 - P(E) = 1 - 0.57 = 0.43.

Sylvia has completed 9 laps.

Step-by-step explanation:

Step 1; Sylvia runs for a total of 2000 meters. Each lap is 200 meters long.   To find the number of laps remaining we need to know the total distance, the distance already covered and the distance on each lap. The distance left to run is equal to the total distance to be run - the distance already ran = 2000 - 1800 meters = 200 meters.

Step 2; The number of laps remaining = The distance left to run/distance on each lap.

The number Number of laps remaining = 200 meters/200 meters

The number of laps remaining = 1 lap.

Final answer:

To determine the number of laps a runner has completed when given the remaining distance to run and the length of each lap, multiply the number of laps by the length of one lap. Answer is 9 laps.

Explanation:

To convert the number of track laps to a distance in meters:

Answer:

n=0

Step-by-step explanation:

We want to solve for n in the equation

-4(3n+3)=5(-2-6n)-2

We expand using the distributive property to obtain:

-12n-12=-10-30n-2

We group similar terms to get:

-12n+30n=-10+12-2

We simplify to get:

18n=0

Divide through by 18 to get:

Answer:

[tex]C=12.75n+12.00\\[/tex]

[tex]C= 15.75 n[/tex]

Step-by-step explanation:

When buying tickets to a play online, they cost $12.75 per ticket plus a $12.00 fee per order. When buying tickets at the box office, they cost $15.75 per ticket. The total cost, c, of going to the play, for n people can by represented by a system of equations.  

    . Write a system of equations that could be used to find how many tickets you have to buy for the cost to be the same.

Let n be the number of people and C be the total cost

Play online

[tex]C=12.75n+12.00\\[/tex]

For Box office

[tex]C= 15.75 n[/tex]

These are the system of equations

To find the cost to be same , make both equations equal to each other and solve for n

The number of tickets bought which will make the online order and box office order equal is 4 tickets

Cost of online order:

C = 12.75n + 12

Cost of box office order:

C = 15.75n

12.75n + 12 = 15.75n

12 = 15.75n - 12.75n

12 = 3n

n = 12/3

n = 4

Answer:

a : b = 19 : 7

Step-by-step explanation:

Given

4a - 5b  : 5a + 4b = 1 : 3

Expressing in fractional form, that is

[tex]\frac{4a-5b}{5a+4b}[/tex] = [tex]\frac{1}{3}[/tex] ( cross- multiply )

3(4a - 5b) = 5a + 4b ← distribute left side

12a - 15b = 5a + 4b ( subtract 5a from both sides )

7a - 15b = 4b ( add 15b to both sides )

7a = 19b ( divide both sides by 7 )

a = [tex]\frac{19}{7}[/tex] b ( divide both sides by b )

[tex]\frac{a}{b}[/tex] = [tex]\frac{19}{7}[/tex]

That is a : b = 19 : 7

Answer:

Step-by-step explanation:

4a-5b:5a+4b=1:3

4a-5b/5a+4b=1:3cross multiply

3(4a-5b)=1(5a+4b)

12a-15b=5a+4b

Collect like terms

12a-5a=4b+15b

7a=19b

Answer:

x - 4 > -9 or x -4 < 9

Step-by-step explanation:

Let's see the definition of absolute value inequality.

i) If  lxl < b, then -b < x < b

ii) If lxl > b, then x > b or x < -b

We are given the inequality  lx - 4l<9

Here we have to use the first case.

Using the above definition of inequality, we can write the given inequality as follows:

-9 < (x - 4) < 9

So the third option is correct.

x - 4 > -9 or x -4 < 9

Step-by-step explanation:

y = 3x - 4  (1)

4x + 3y = 1 (2)

if we substitute y by 3x - 4 in the second equation we get

4x + 3(3x-4) = 1 ⇒ 4x + 9x - 12 = 1 ⇒ 13x = 13 ⇒ x = 1

now ,we substitute x by 1 in the first equation

y = 3(1) - 4 = 3 - 4 = -1

Answer:

3/4 of the pie is left.

Step-by-step explanation:

Step 1: Cut the pie into 2 equal pieces. Each piece is 1/2 of the pie.

Step 2: Cut each half in half. Each new smallest piece is now 1/4 of the pie.

Step 3. Cut each 1/4 pie in half. Each new smallest piece is 1/8 of the pie.

Now 2 of the smallest pieces are eaten.

That means 2 of the 1/8 pie size are eaten.

2 * 1/8 = 2/1 * 1/8 = 1/4

1/4 of the pie was eaten.

The remaining part is 1 pie minus 1/4 pie.

1 - 1/4 = 1/1 - 1/4 = 4/4 - 1/4 = 3/4

Answer: 3/4 of the pie is left.

Answer:y=42000-2000x

Y is price so that’s be 42000 minus 2000 every year

Answer:

[tex]y=42,000 - 2000x[/tex]

Step-by-step explanation:

The y is the total value of the car after everything that needs to be taken account of has been accounted to. You're finding the y and what the price is after x amount of years. The initial amount is 42,000 so whatever the cost of the car has depreciated would be subtracted from it. 2,000 dollars per year means what ever x is for year, let's say 5. The amount of money that the car has depreciated over the course of 5 years would be 5 multiply by 2,000. Hopes this help!
