The perimeter of a rectangular pool is 240 yd. If the length is 30 yd unless the four times the width, find the length and the width.

Answer:

5 five dollar and 7 one dollar

Step-by-step explanation:

1x+5y=32

x+y=12

using elimination method

+x-x-y+5y-32+12=0

4y-20=0

4y=20

y=20/4 =5

so, if. y is 5 then x is

5y+x=32

5(5)+x=32

25+x=32

x=32-25

x=7

Answer:

Here u go bro. You have to just replace y and x with zero and then draw the I think structure say say:')

Answer:

1/2 = 0.5 and 3/4 = 0.75

Use a proportion: 0.5/2.60 = 0.75/x

Cross multiply: 0.5x = 0.75*2.60

So x = 0.75*2.60/0.5 = 3.90

Answer:

(i) A = {1}, B = {1, 2}, (ii) A = empty set, B = {1, 2, 3}, (iii) A = {a, b, c}, B = {a, b, c}, (iv)  A = {7, 8, 9, 10}, B = {7, 8, 9, 10, 11, 12}

Step-by-step explanation:

The idea: A U B = the set of all elements (from a Universal set, like the set of all integers) that are in at least one of the sets A or B.  So, for the equation     A U B = B to be true, the set A must be a subset of the set B, because otherwise  A U B would contain at least one element not in B, making the equation A U B = B false (set B would be a proper subset of A U B).  So, if       A = {1, 2, 3, 4} and B = {1, 2, 3}, then A U B = {1, 2, 3, 4}, and A U B = B would be false.  However, if A = {1, 2, 3} and B = {1, 2, 3, 4}, then A U B = B would be true.

Answer:

Slope: m=-1

y-intercept: (0,7)

slope intercept form: y=-x+7

Answer:

Step-by-step explanation:

4:C(X) = 17x - 10, the first question wants you to find how much 5 ticket costs, so replace x with 5 so c(x)= 17(5)-10 which equals 75$

4a: 4a wants you to find how many tickets you can buy for  130$. So first replace the y or c(x) with 130 x, which gives 130=17x-10. Now we find x, first add 10 to both sides to cancel the -10, 140=17x, then divide 17 from both sides which gives 8.235, so we can buy 8 tickets.

4b: It is discreet because it cannot be broken down into decimals or fractions, since you cannot have a halve of a ticket.

4c: c(0) means the y-intercept

4d: the range is  7 to positive infinite

Proportional relationship:

Use a pair of points (0.14, 0.7) to find the value of k:

The function is:

Fill in the table:

Using probability concepts, it is found that:

a) Since [tex]P(A)P(B) \neq 0[/tex], the events are not mutually exclusive.

b) 0.997 = 99.7% probability that the  can does not have a puncture or does not have a smashed edge.

Item a:

Two events, A and B, are mutually exclusive if:

[tex]P(A \cap B) = 0[/tex]

In this problem:

The problem also states that the probability of neither is [tex]P(A \cap B) = 0.893[/tex].

Since [tex]P(A)P(B) \neq 0[/tex], the events are not mutually exclusive.

Item b:

Using Venn probabilities, the "or" probability is given by:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

With the given values:

[tex]P(A \cup B) = 0.96 + 0.93 - 0.893 = 0.997[/tex]

0.997 = 99.7% probability that the  can does not have a puncture or does not have a smashed edge.

Step-by-step explanation:

r = 32/40 = 0.8

S10 = 40(1- (0.8)^10)/ (1- 0.8)

= 40(1 - 0.107) / 0.2

= 200(1.107)

= 221

Answer:

9 is 50% of number 18

'cuz u should do 18/2=9

Answer:  

9 / 50% = Y / 100%

Solve for Y  

50Y = 9 x 100

50Y = 900

Y = 900 /100 = 18

note: when i put / it means fraction

so the answer to your question is 18 :D

Answer:

The speed of the boat in still water is 12 miles per hour, while the speed of the current is 9 miles per hour.

Step-by-step explanation:

We'll use x as the speed of the boat in still water in miles per hour.

We'll use y as the speed of the current in miles per hour.

When the boat is traveling downstream, the speed of the boat is helped by the speed of the current and the net speed is x + y.

When the boat is traveling upstream, the current opposes the movement of the boat, and the net speed is x - y.  

Using a table where d = distance in miles, r = rate or speed in miles per hour, and t = time in hours can help figure out how to figure out this problem.

─────────────────

Downstream│210│(x + y)│10

Upstream│210│(x - y)│70

─────────────────

Recall that distance = rate x time or d = rt.

210 = (x + y)10 ➤ Equation from downstream information.

210 = (x - y)70 ➤ Equation from downstream information.

210 = 10x + 10y ➤ Distribute.

210 = 70x - 70y ➤ Distribute.

7 × 210 = 7 × 10x + 7 × 10y ➤ Multiply the 1st equation by 7.

1470 = 70x + 70y ➤ Add the 1st equation to the 2nd.

210 =70x - 70y ➤ Add the 1st equation to the 2nd.

1680 = 140x

─────────────────

1680/140 = 140x/140

x = 12

210 = (12 + y)10 ➤ Substitute x = 12 into one of the original  equations to find y.

210 = 120 + 10y

-120 - 120

90 = 10y

90/10 = 10y/10

y = 9

Answer:

false and then true

Step-by-step explanation:

Hope this helps :)

Answer:

First one is False, second one is true.

Step-by-step explanation:

For the first one, the left side of the equation would equal -6/3, and the left side would be 3/-6. When simplified it would be: -2 = -1/2, which is incorrect.

For the second one, the left side and the right side are the same because either way you put it, they are still being multiplied, and the order doesn't matter. The end result will be -72 = -72, which is correct.

Answer:

Slope is -5 and y-intercept is 90.

Step-by-step explanation:

Use the two values that you circles (4, 70) and (6, 60) .

slope (m) = the change in y-value/ (the change in the x-values).

m = (70 - 60)/(4 - 6) = 10/-2  = -5

The y-intercept is the value of "b" in the equation y = mx + b.

 Using  y = mx + b,  substitute the value m and use point of your points (4, 70).

   y = mx + b

   70 = -5(4) + b     Now solve for "b".

  70 = -20 + b

 +20 = +20      

   90 = b
