Determine the number of solutions for the system 2x+3y=5 and -9y=6x-15

Answers

9514 1404 393

Answer:

  infinite number of solutions

Step-by-step explanation:

The two equations describe the same line.

Adding 9y+15 to the second equation makes it be ...

  15 = 6x +9y

Dividing that by 3 gives you ...

  5 = 2x +3y . . . . . . identical to the first equation

The lines intersect at every point, so there are an infinite number of solutions.

Answer:

[tex]x\approx 7.88[/tex]

Step-by-step explanation:

Since we are given the angle and the hypotenuse and we want to find the side opposite to the angle, we can use the sine ratio. Recall that:

[tex]\displaystyle \sin\theta^\circ =\frac{\text{opposite}}{\text{hypotenuse}}[/tex]

Substitute:

[tex]\displaystyle \sin21=\frac{x}{22}[/tex]

Solve for x:

[tex]x=22\sin 21[/tex]

Use a calculator (make sure you're in Degrees mode!):

[tex]x\approx 7.88[/tex]

It takes Alice 90 minutes to put a futon frame together, and it takes Maya 60 minutes to put the same
type of frame together. If they worked together, how long would it take to put a frame together?

Answers

Answer:

36 minutes

Step-by-step explanation:

The equation to determine the time together is

1/a + 1/b = 1/c  where a and b are the times alone and c is the time together

1/90  + 1/ 60 = 1/c

Multiply each side by 180c to clear the fractions

180c( 1/90  + 1/ 60 = 1/c)

2c + 3c = 180

5c = 180

Divide each side by 5

5c/5 = 180/5

c =36

) A desk organizer sells for $35, which includes a markup rate of 60% based on the selling price.
a. Find the markup.
b. Find the cost.

Answers

Answer: a. $21

b. $14

Step-by-step explanation:

Selling price of desk organizer = $35

Markup rate = 60%

a. The markup will be:

= Markup rate × Selling price

= 60% × $35

= 0.6 × $35

= $21

Therefore, the markup is $21

b. The cost will then be:

Cost price = Selling price - Markup

= $35 - $21

= $14

There is a bag filled with 3 blue and 4 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 blues?

Answers

3 of 7 and the chances of getting red is 4 of 7

Step-by-step explanation:

Answer:  9/49

====================================================

Explanation:

The fraction 3/7 represents the probability of picking a blue marble since there are 3 blues out of 3+4 = 7 total.

Because the first marble is put back, this means the probability of picking blue does not change. So 3/7 is the probability of picking another blue marble.

Overall, we have (3/7)*(3/7) = 9/49 as the probability of picking two blues in a row.

Step-by-step explanation:

Answer:

49 3/5

Step-by-step explanation:

First, convert 12 2/5 into an improper fraction. You should get 62/5. We know that dividing fractions is the same thing as multiplying by the other fraction's reciprical (flip). So, 62/5 divided by 1/4 is the same thing as 62/5*4/1 (4). Lastly multiply straight across to get 248/5. Simplify to get 49 3/5.

Given the statement 11^(n -6) is divisible by 5 for every positive integer n. What must be shown in the induction step?

Answers

Answer:

Proved

Step-by-step explanation:

The given data is:

[tex]11^n - 6[/tex] not [tex]11^{n - 6[/tex]

Required

Prove by induction that it is divisible by 5

Assume [tex]n = k[/tex]

So, we have:

[tex]11^k - 6 = 5p[/tex] where p is a positive digit

Rewrite as:

[tex]11^k = 5p + 6[/tex]

To solve further, we have to prove that [tex]11^k - 6[/tex] is true for [tex]n=k+1[/tex]

So, we have:

[tex]11^{k+1} - 6[/tex]

[tex]11^{k+1} - 6 = 11^k * 11 - 6[/tex]

Add 0

[tex]11^{k+1} - 6 = 11^k * 11 - 6 + 0[/tex]

Replace 0 with [tex]-5 +5[/tex]

[tex]11^{k+1} - 6 = 11^k * 11 - 6 - 5 + 5[/tex]

[tex]11^{k+1} - 6 = 11^k * 11 - 11- 5[/tex]

Factorize

[tex]11^{k+1} - 6 = 11 (11^k - 1)- 5[/tex]

Substitute [tex]11^k = 5p + 6[/tex]

[tex]11^{k+1} - 6 = 11 (5p + 6- 1)- 5[/tex]

[tex]11^{k+1} - 6 = 11 (5p + 5)- 5[/tex]

Factorize

[tex]11^{k+1} - 6 = 11 *5(p + 1)- 5[/tex]

Factorize

[tex]11^{k+1} - 6 = 5[11(p + 1)- 1][/tex]

In each diagram, abc is a straight line. Find the unknown angles.

Answers

Answer:

The value of ∠b = 180°

Step-by-step explanation:

Given that;

ABC is a straight line

Another angle is 137°

Find:

The value of ∠a

The value of ∠b

Computation:

We know that, ABC is a straight line

So,

137 + The value of ∠a = 180

The value of ∠a = 180 - 137

The value of ∠a = 43°

The value of ∠b = 360 - 137 - The value of ∠a

The value of ∠b = 360 - 137 - 43

The value of ∠b = 180°

20 = x

Step-by-step explanation:

All interiror angles in this triangle will equal 180

Set your formula up as 180 = x+5+7x-5+x then solve for x

180 = x+5+7x-5+x

180 = x + 7x + x +5 - 5

180 - 5 + 5 = 9x

180 = 9x

180 / 9 = x

20 = x

You can check your result by pluging in 20 for all x

180 = 20+5+7*20-5+20

180 = 180

(a) What is the probability that all the committee members are girls?
(b) What is the probability that the committee has three girls and three
boys?

Answers

The number of ways 6 girls can be chosen from 24 girls is C(24, 6)

The number of ways 6 students can be chosen from 46 students is C(46, 6)
= 46! / (40! x 6!) = 9366819

a) P(6 girls are chosen) = 134596 / 9366819 = 0.01437 (4sf)

The number of ways 3 boys and 3 girls can be chosen is C(22, 3) x C(24, 3)
= [22! / (19! x 3!)] x [24! / (21! x 3!)] = 3116960

b) P(3 boys and 3 girls are chosen) = 3116960 / 9366819 = 0.3328 (4 sf)
