Answer:

38oz

Step-by-step explanation:

6-3=3   3pounds-10ounces=38

3lb=48oz   48-10=38

Answer:

Step-by-step explanation:

3 pounds = 48 ounces

48 ounces + 10 ounces = 58 ounces

-----------------------------------------------------------------------------------------------------------------

6 pounds = 96 ounces

96 ounces - 58 ounces = 38 ounces

Answer:

  D.  9

Step-by-step explanation:

The segment lengths are equal, so ...

  x^2 = 90-x

  x^2 +x -90 = 0 . . . . . . add x-90 to put in standard form

  (x +10)(x -9) = 0 . . . . . factor

The solutions are the values of x that make the factors zero: -10, 9.

The positive value of x is 9.

Answer:

148

Step-by-step explanation:

a/22=74

a=1628

1628/11=148

Answer:

148

Step-by-step explanation:

the # is divided by 22 to get 74, so to know what # is, we need to multiply 22 and 74, which fives you 1,628. Then, you just divide that by 11, which give you 148 :)

Answer:

Step-by-step explanation:

Yes, they are. The like term is the variable x. The combine to form 0

Answer:

X ∪ Y = 1, 3, 4, 5, 7, 9,

X ∪ Z = 1, 2, 4, 6, 8, 9

X ∩ Y = 1, 9

X ∩ Z = 4

Y ∩ Z = ∅

Explanation:

X = [1, 4, 9]

Y = [1, 3, 5, 7, 9]

Z = [2, 4, 6, 8,]

Answer:

Habiba will pay $262.20 of Interest.

Step-by-step explanation:

Simple Interest

Simple interest is a method of calculating the interest charge on a loan. The Interest (I) is determined by multiplying the yearly interest rate (r) by the principal (P) by the number of years that elapsed between payments (t).

The formula to calculate the interest Habiba will pay is:

I=P.r.t

The values are:

P=950

t=3 years

r=9.2% yearly= 0.092

Substituting the values:

I=950*0.092*3

I=262.20

Habiba will pay $262.20 of Interest.

Answer:

the probability of obtaining a favorable outcome increases as the number of trials increases

Step-by-step explanation:

The law of large numbers occupies an important place in probability statistics especially as it regards the outcome of experiments.

A simple statement of this law is that; when an experiment is independently repeated a large number of times, the average result, that is obtained is close to the expected value.

Hence, the probability of obtaining a favorable outcome increases as the number of trials increases.

Answer:

p= -7/5

Step-by-step explanation:

Answer:

Part 1

1.) -105

2.) 120

3.) 15

4.) -200

5.) 40

6.) 16

7.) 240

Step-by-step explanation:

1.) Do 7 x 15, which is 105, then since 15 is a negative and 7 is positive, the product is negative.

2.) Do 5 x 24, which is 120, and sine both 5 and 24 are negative, they cancel each other out and the product is positive.

3.) Do 75 / 5, which is 15, and since both 75 and 5 are negative, they cancel each other out and the quotient is positive.

4.) Do 25 x 8, which is 200, and since 25 is negative and 8 is positive, the product is negative.

5.) Do 120 / 3, which is 40, and since both 120 and 3 are positive, the quotient stays positive.

6.) Do 80 / 5, which is 16, and since both 80 and 5 are negative, they cancel each other out and the quotient is positive.

7.) Do 16 x 15, which is 240, and since both 16 and 15 are negative, they cancel each other out and the product is positive.

Answer:

Step-by-step explanation:

The length of a side can be found using the distance formula:

  d = √((x2 -x1)^2 +(y2 -y2)^2)

For P1P2, this gives ...

  d = √((0-(-2))^2 +(1-(-1))^2) = √(4+4) = √8

  P1P2 = 2√2

__

The same ∆x and ∆y apply to P1P3, so we know ...

  P1P3 = 2√2

__

The lengths of P1P2 and P1P3 are the same, so the triangle is isosceles.

__

The length of P2P3 can be found by subtracting the y-coordinates:

  P2P3 = 1 -(-3)

  P2P3 = 4

__

We note that the slope of P1P2 is 2/2 = 1, and the slope of P1P3 is -2/2 = -1. The product of these slopes is (1)(-1) = -1, so we know those lines are perpendicular. The triangle is a right triangle.

Step-by-step explanation:

In the given division, when 24.725 is divided by 215,

Step 1 is the wrong step.

Quotient in first step will be 0.1 .

Part C.

215) 24.725 (0.115

      215

          322

          215

           1075    

           1075

                0

Therefore, the correct way to divide should be as agove.

Quotient after division should be 0.115.

Step-by-step explanation:

Answer:

Hello,  

we know that to find the GCF we descompose the numbers and then we multiply the common terms with the lowest exponent. So we first descompose 210:

210   | 2

105   | 3

 35   | 5

   7   | 7

   1    

210= 2x3x5x7

Now one possible solution is 14 because:

14   | 2

 7   | 7

 1

As you can see 2 and 7 are common terms, so:

GCF= 2x7

GCF=14   -->  It's correct

Then, if we analyze it, we'll realize that we have an infinitive number of solutions. The only requirement is that "M" must have 2 and 7 when we descompose it.

For example:

M= 2²x7x3x11

M=924

924 is another possible solution, it doesn't matter if 2 or 7 repeat, since I said the GCF is the multiplication of the common terms with the LOWEST exponent. That's all.

Answer: THE ANWSER IS B

Answer: y=x+5

Step-by-step explanation:

So the dots are going at a slope of 1 up and 1 right each time, so your slope would be 1, or simply x if you times it. To line it up with the slope, you have to move up 5 on your y-axis, known as your b. Then from there, you go up 1 over 1 which will line up with all the dots.
