Answer:

There are infinite solutions.

Step-by-step explanation:

A system of linear equations can have infinite solutions if the equations are equivalent. This means that one of the equations is a multiple of the other. It also means that every point on the line satisfies all of the equations at the same time.

Answer:

125, 100, 80,64,51.2,40.96...

Step-by-step explanation:

y=[tex]\frac{4}{5}[/tex]x

So let's work backwards!

[tex]\frac{5}{4}[/tex](80)

=100

Then...

[tex]\frac{5}{4}[/tex](100)

=125

Hope this helps! :D

Answer:

  125, 100

Step-by-step explanation:

Perhaps the terms of your series are supposed to be ...

  __, __, 80, 64, 51.2, 40.96, ...

The common ratio is 64/80 = 0.8, so the recursive relation is ...

  t[n] = 0.8×t[n-1]

__

Solving for the previous term, we find ...

  t[n]/0.8 = t[n-1] . . . . . . divide by 0.8

or ...

  t[n-1] = 1.25×t[n] . . . . . rearrange

Then the term previous to 80 is 1.25×80 = 100.

And the term previous to 100 is 1.25×100 = 125.

The first two terms of the geometric sequence are 125 and 100.

Question 1: x=12.5

6x+4x+2x+30=180

(One full line forming a semi circle would equal to 180 degrees all the angles given would therefore equal up to that value)

Add like terms to simplify;

12x+30=180

Use inverse operations to isolate the variable!

180-30=150

150/12=12.5

Check ur work!

6(12.5)+4(12.5)+2(12.5)+30=180

75+50+25+30=180

180=180

Question 2: Angle EAF = 25 degrees

Since x equals 12.5

and the equation given to represent the angle is 2x

2(12.5)=25

Question 3: Angle DAE= 50 degrees

x=12.5

Angle DAE=4x

4(12.5) = 50

Question 4: Angle CAD= 75 degrees

x= 12.5

Angle CAD= 6x

6(12.5) = 75

(if any are incorrect i apologize beforehand)

Answer:

s = 28/9

Step-by-step explanation:

d/(7 x 2) + d/(2 x 2) = d/s

d/14 + d/4 = d/s

18d/56 = d/s

18/56 = 1/s

s = 28/9

The average speed is 28/9.

Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. Even with varying speed, the values of total time and the total distance covered can be used, and with the help of the formula for average speed, we can find a single value to represent the entire motion.

Example

Using the average speed formula, find the average speed of Sam, who covers the first 200 kilometers in 4 hours and the next 160 kilometers in another 4 hours.

To find the average speed we need the total distance and the total time.

Total distance covered by Sam = 200Km + 160 km = 360 km

Total time taken by Sam = 4 hour + 4 hour = 8 hour

Average Speed = Total distance covered ÷ Total time taken

Average Speed = 360 ÷ 8 = 45km/hr

The average speed of a body is equal to the total distance covered, divided by the total time taken. The formula for average speed is given as:

Average Speed Formula:

Average Speed = Total distance covered ÷ Total time taken

Given:

halfway at 2mph and runs the rest of the way at 7mph

d/(7 x 2) + d/(2 x 2) = d/s

d/14 + d/4 = d/s

18d/56 = d/s

18/56 = 1/s

s = 28/9 mph

However, that's the length of "c" and you're looking to drag it in. So,o you drag in 10^2+7^2=a^2.

Then, as shown by the first picture attatched, you can drag in the one with "c" and "a" with the five shown.

Step-by-step explanation:

To find "c" the diagonal, as explained, you need to use the theorem twice. You can first use it by finding "a", as you already have "b". To find a, you do 10^2+7^2=a^2, the hypotenuse.

100+49=149.

So, a is root 149.

a^2+b^2=c^2 so

149+25=174

a) The length of a, a² = 10² + 7²

b) The fourth Figure will be Drag in Last column.

The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

Given:

As From the Figure, a² = 10² + 7²

a² = 100 + 49

a² = 149

a= √149

To find c the diagonal,

a² = 10²+ 7²

a² = 149

a = √149

Now, a²+b²=c²

The fourth Figure will be Drag in Last column.

Multiplication and division both need to have a common denominator or else you would get an incorrect answer. Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators.

The solution is, the required probability is 15/36 .

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

from the given table, we get,

total number of sample space is 6 x6 = 36.

now, we get, that, the number of getting sum less than 7 is 15

we have,

probability = no. of the event/ no. of total outcome

                  = 15/36

we get this,

because if you solve everything below 7 that would give you 15 problems and there is 36 outcomes bc 6 x6 is 36.

Hence, The solution is, the required probability is 15/36 .

Step-by-step explanation:

As shown, you add four by each.

4+4=8

8+4=12

So, 12+4=16

16+4=20

Answer:

16 and 20

Step-by-step explanation:

In the arithmetic squence, we can tell that 4 is being added to each term.

Thus, we obtain the following rule:

To find the next two terms in the sequence, we need to determine the fourth and fifth term of the sequence. Let us substitute the "4" and "5" in the rule to determe the next two terms in the sequence.

Determining the 4th term of the sequence:

⇒ 4x

⇒ 4(4)

⇒ 16

Determining the 5th term of the sequence:

⇒ 4x

⇒ 4(5)

⇒ 20

Thus, the next two terms are 16 and 20.

PART A

If 4 pounds = 10 dollars...

4/2 = 2

10/2 = 5

So for 2 pounds, it would cost $5.00

Now for the 1 pound one

4/1 = 4

10/4 = 2.5

For the 1 pound one, it would cost $2.50

PART B

We know that 4 pounds = 10 bucks

Since 1 is 1/10 of 10 (in the cost section), we have to apply this to the pounds section. 4/10 = 0.4. Therefore, $1 = 0.4lb

Now for the last blank...

Since $1 = 0.4, we multiply that by 9. 0.4 x $9 = 3.6lb
