Step-by-step explanation:

.37x.42=.1554

Answer:

He spent on 16 minutes

Step-by-step explanation:

Given

[tex]Base\ Amount = \$40[/tex]

[tex]Charge = \$0.5[/tex] per minute

[tex]Total = \$48[/tex]

Required

Determine the number of minutes

Let the number of minutes be n

If 1 minute costs $0.5

n minutes would cost $0.5n

The relationship between the given parameters is

[tex]Total = Base\ Amount + Charges[/tex]

Substitute values for each of the above

[tex]48 = 40 + 0.5n[/tex]

Solve for 0.5n

[tex]0.5n = 48 - 40[/tex]

[tex]0.5n = 8[/tex]

Solve for n

[tex]n = 8/0.5[/tex]

[tex]n = 16[/tex]

He spent on 16 minutes

Answer: You can tell when a number is undefined when the number is being divided by zero.

Step-by-step explanation:

Diving a number by zero does make a real situation . You can't divide something by nothing.

2/0 = is undefined

3/0  is undefined

Answer:

the answer is A.

Step-by-step explanation:

I just took the test

Answer: a. 1) we can scale a rate by the reciprocal of its 2nd term to find the unit rate..This makes sense as we know with rates we can divide and that dividing is equivalent to multiplying by the reciprocal.

b. 2) To find the unit rate, divide the numerator and denominator of the given rate by the denominator of the given rate.

a. 2) what we need to know to solve the problem is first the given fractions 3/4 and 1/5 and 2/3 and 1/6. and we need to find what we need to do to those which is division.

Answer:

1(-4)

Step-by-step explanation:

I think it's 1(-4)

since it's moving 1 number over, four times. and if you multiply, the answer -4.

I'm pretty sure this is the answer.

Answer:

Step-by-step explanation:

Answer: they are they same

Step-by-step explanation:

x = # of days

y = total calories

Simba = 1000 + 140x = y

Cuddles = 2650 - 190x = y

Let's set both of these equations equal to each other

1000 + 140x = 2650 - 190x

Add 190x to both sides and subtract 1000 from both sides.

330x = 1650

Divide each side by 330

x = 5

After 5 days, they will be consuming the same amount of calories.

To find out how many calories they will be consuming, let's plug 5 into our Simba equation.

1000 + 140(5) = y

Multiply 140 by 5

1000 + 700 = y

Simplify

1700 = y

They will be consuming 1,700 calories each day.

Answer:

$23.60

Explanation:

you can make an equation out of the information provided! it will look something like:

12.5(.7)+13.5(1.1)

(12.5 is the amount of green ribbon and .7 is the cost per foot, so you would multiply them to find the total cost of the ribbon. do the same thing for the polka dot ribbon; 13.5 feet times 1.1, the cost per foot, will give u the total cost of polka dot ribbon. then, add them together for the total cost of both ribbons!!)

12.5×.7=8.75

13.5×1.1=14.85

8.75+11.85=23.6, or $23.60!!

Answer:

350

Step-by-step explanation:

Total ratio: 12

600/12

each ratio has 50 students

that means the boys are 5 * 50= 250

the girls are 7 * 50 =350

Think of the binomial squared as its own squared term.

Since the squared term is isolated, we can take the square root of both sides.

On the left, the square root removes the square and we have x + 7.

On the right, the square root of 81 is ± 9.

*Always use plus or minus when taking square root of both sides*

So we have x + 7 = ± 9.

Now, split things up into two separate equations.

Solving each equation from here, we find that x = -2 or x = 16.

We can write this as {-2, 16}.

The solutions to the equation [tex](x + 7)^2 = 81[/tex]  are x = 2 and x = -16.

The correct option is D.

To find the solutions to the equation [tex](x + 7)^2 = 81[/tex] , we can start by taking the square root of both sides of the equation. However, since we have a squared term, we need to consider both the positive and negative square roots.

Taking the square root of both sides, we have:

[tex]x + 7 = \pm \sqrt{81}[/tex]

Simplifying the right side, we get:

x + 7 = ±9

Now, we can solve for x by subtracting 7 from both sides:

x = -7 ± 9

This gives us two possible solutions:

x = -7 + 9 = 2

x = -7 - 9 = -16

Hence, the correct answer is option D: -16 and 2.

Answer:

x - 9 = y +2 => y = x - 11

It is linear because the exponent of x number is equal to 1.

Answer:

Step-by-step explanation:

Given the sample data 2 6 15 9 11 22 1 4 8 19, before we can get the standard deviation, we need to first calculate the mean.

mean = 2 +6 +15 +9 +11 +22 +1 +4 +8 +19/10

mean = 97/10

mean = 9.7

Standard deviation for ungrouped data is expressed using the formula;

[tex]S = \sqrt{ \dfrac{\sum(x-\overline x)^2}{n-1} }[/tex]

[tex]\overline x \ is\ the \ mean\\n \ is \ sample \ size[/tex]

[tex]S = \sqrt{\frac{(2-9.7)^2+(6-9.7)^2+(15-9.7)^2+(9-9.7)^2+(11-9.7)^2+(22-9.7)^2+(1-9.7)^2+(4-9.7)^2+(8-9.7)^2+(19-9.7)^2}{10-1} }\\ S = \sqrt{\frac{(-7.7)^2+(-3.7)^2+(5.3)^2+(-0.7)^2+(1.3)^2+(12.3)^2+(-8.7)^2+(-5.7)^2+(-1.7)^2+(9.3)^2}{10-1} }\\\\S = \sqrt{\dfrac{59.29+13.69+28.09+0.49+1.69+151.29+75.69+32.49+2.89+86.49}{10-1} }\\\\\\S = \sqrt{\dfrac{452.1}{9} }\\\\S = \sqrt{50.23}\\ \\S = 7.08\\\\S \approx 7.1[/tex]

Hence the standard deviation of the sample data is 7.1

Answer:

  7, 9

Step-by-step explanation:

The average of the two is the even integer between them:

  average = sum/2 = 16/2 = 8

The two odd integers are 7 and 9.

_____

In this case, the divisor for the average is 2, because there are 2 integers in the sum.

Work Shown:

1/5 = 3/15 after multiplying top and bottom by 3

1/5 + 3/15 = 3/15 + 3/15 = (3+3)/15 = 6/15

Reduce that result to get

6/15 = (2*3)/(5*3) = 2/5

So 6/15 reduces to 2/5

Overall,

1/5 + 3/15 = 2/5
