Answer:

3.88

Step-by-step explanation:

Given that

42x = 163

It set 2x = 3

and x = 32

We need to tell the mistake and mentioned the correct answer

if we solve the above equation i.e.

42x = 163

x = 3.88

Hence, in this way it should be calculated

The same would be considered and relevant

Hence, the correct answer is 3.88

Answer:

Mila had $48 initially

Step-by-step explanation:

Let the amount of money they had be x

Mila spent $42; what is left would be x-42

Samuel spent $36: what is left would be x-36

So, what Mila had left is half of what Samuel has; that would be;

x-42 = 1/2(x-36)

2(x-42) = x -36

2x-84 = x -36

2x - x = 84 -36

x = $48

Answer:

7x + 27 = -17

Step-by-step explanation:

2x + 5x = 7x

3y + (-y) = 2y

-5 + (-12) = -17

Combine them to make the added equation.

7x + 2y = -17.

405 gallons of water in the tank in 45 minutes.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

Given that A water tank is filled with a hose.

The table shows the number of gallons of water in the tank compared to the number of minutes the tank was

being filled.

The line of best for this data is g = 9m - 0.17.

We need to find when it is 45 minutes.

We have to put m value as 45 to find the number of gallons

g=9(45)-0.17

g=405-0.17

g=404.83

Hence, 405 gallons of water in the tank in 45 minutes.

Answer:

b)25/125

c)80/125

d)45/125

e)10/35

Step-by-step explanation:

hope it is correct

The statements which are correct are B, C and E.

Relative frequency is defined as the ratio of the frequency by the total count of the data values.

We have to find the relative frequency in each option.

A) Frequency of "like snowmobiles" and "like skateboards" = 80

Total count = 160

Relative frequency of "like snowmobiles" and "like skateboards" = 80 / 160 = 0.5 = 50%

B)  Frequency of "like snowmobiles" and "do not like skateboards" = 25

Total count = 160

Relative frequency of "like snowmobiles" and "do not like skateboards" = 25 / 160 = 0.15625 = 15.6%

C) Frequency of "like snowmobiles" and "like skateboards" = 80

Total row frequency = 105

The row conditional relative frequencies of "like snowmobiles" and "like skateboards" = 80 / 105 = 0.7619 = 76.19% ≈ 76.2%

D) Frequency of "do not like snowmobiles" and "like skateboards" = 45

Total row frequency = 55

The row conditional relative frequencies of "do not like snowmobiles" and "like skateboards" = 45 / 55 = 0.81818 = 81.82%

E) Frequency of "do not like snowmobiles" and "do not like skateboards" = 10

Total column frequency = 35

The column conditional relative frequencies of "do not like skateboards" and "do not like snowmobiles" = 10 / 35 = 0.2857 = 28.57% ≈ 28.6%

Hence the correct statements are B, C and E.

Answer:

y = -1

Step-by-step explanation:

1) first, you would have to substitute x, the input, with 30, y = 14-0.5(30)

2) then, you would multiply 0.5 and 30 together which gets y=14-15

3) lastly, 14-15 equals -1 so y = -1

Answer:

Answer is -1

Step-by-step explanation:

First we know that x = 30, and in 0.5x we can plug in 30 because x = 30. So the equation is 14 - 0.5(30), now multiply 0.5 * 30 which will give you 15. Now the new equation is y = 14 - 15, 14 - 15 will give you -1. And that is y, Y = -1

Answer:

Step-by-step explanation:

The amount of water that was in the cooler initially is dependent on the amount of water in the cooler now(that is, what is remaining). And also, the rate of which water was being used. If the rate at which water was being used was 10 liter/hour, this means that an 11 liter cooler would remain 1 liter after an hour. Because 10 liters must have been used within the said hour.

Answer:

10 liters

Answer:

x = 6

y = 6[tex]\sqrt{2}[/tex]

z = 12

Step-by-step explanation:

the ratio of sides in a 30-60-90° triangle is, respectively, 1 : [tex]\sqrt{3}[/tex] : 2

therefore, 'x' must have a measure of 6

which means the hypotenuse must have a measure of 12

other triangle is a 45-45-90° triangle whose sides are in a ratio of 1 to [tex]\sqrt{2}[/tex]

this means that 'y' must be 12/[tex]\sqrt{2}[/tex] which is 6[tex]\sqrt{2}[/tex]

'z' must be 6[tex]\sqrt{2}[/tex] · [tex]\sqrt{2}[/tex] = 12

Answer:

J' = (-15, -10)

K' = (5, 20)

L' = (20, 10)

Step-by-step explanation:

Given the coordinates J(–3, –2), K(1, 4), and L(4, 2)

D5(ΔJKL) means we need to dilate the coordinates by a constant of 5

To do that, we will multiply the coordinates by a value of 5

D5(ΔJKL)

J' =  (5(–3), 5(–2)),

J' = (-15, -10)

K' = (5(1), 5(4))

K' = (5, 20)

L' = (5(4), 5(2))

L' = (20, 10)

Answer:

x < -2 (No, he shouldn't have reversed the inequality symbol).

Step-by-step explanation:

Given the algebraic expression;

19 - 2(1 - x) < 13

Opening up the bracket, we have;

19 + (-2*1) + (-2*-x) < 13

19 + (-2) + (2x) < 13

19 - 2 + 2x < 13

17 + 2x < 13

Rearranging the equation, we have;

2x < 13 - 17

2x < -4

Dividing both sides by 2, we have;

x < -2

Hence, your friend shouldn't have reversed the inequality symbol (sign).

Note: you should only flip the inequality symbol (sign) when you're dividing by a negative number such as -2.

For example, if we had re-arranged the equation as;

17 - 13 < -2x

4 < -2x

Dividing both sides by -2, we have;

4 > x

Answer:

23 feet > m ; or m must be less than 23 feet.

Step-by-step explanation:

Let's call this final, or third side, m.

According to the Triangle Inequality Theorem, or the Gator Theorem - as some call it - "The sum of the lengths of any two sides of a triangle is greater than the length of the third side."

So,

[tex]2+5>m\\7>m[/tex]

So, we know that m must be less than 7 meters! However, we are NOT done. We must convert M's measurement of meters into feet.

A meter is about 3.28 feet, so using that conversion...

[tex]3.28 * 7 = 22.96\\[/tex]

That is about 23 feet :)

Answer: 83

Step-by-step explanation: 17% of 500 is 85. If 17% is empty, that means that you'd take away that 15%. 500 - 85 = 415. If each page holds 5 cards, we need to split those cards up between the pages. 415/5 = 83, so 83 pages will be used.
