Answer:

-15 + -3 = -18

Rob owes his father $18.

Step-by-step explanation:

Rob has to pay back the same amount of money that he took. Since he took 15 dollars, he has to give back 15 dollars which makes the 15 negative. The same goes for the 3 in the equation.

To find out the total amount Rob has to pay back, we have to add -15 and -3, which is -18.

Answer:

$13.76

Step-by-step explanation:

Cost at store A = $29.35

Cost at store B = $32.79

Difference in price at both stores :

Difference = store B - store A

Difference in price = $32.79 - $29.35 = $3.44

Extra cost to f purchasing 4 video games at store B:

Difference in price * number of video games

$3.44 * 4 = $13.76

The statement which is true among the answer choices is; Only 140 is an outlier.

An outlier by definition is a data point that differs significantly from other observations which may be due to an error and hence, may cause difficulty in statistical evaluation.

On this note, it follows that only 140 is an outlier among the answer choices.

Answer: She jump ropes 7/3 or 2 1/3 of an hour every week

Step-by-step explanation: This is because she jump ropes 1/3 each day and there's 7 days in a week so 7/3 or 2 1/3(2 hours and 20 minutes)

I hope you are having a nice day!

Answer:

2 hours 33 minutes

Step-by-step explanation:

1/3 of an hour is 20 minutes

20 times 7 is 140

140 divided by 60 is 2.33 hours

so 2 hours and 33 minutes

Answer:

166 dogs were at the veterinary hospital

Step-by-step explanation:

Here, we want to know the number of dogs that were at the veterinary hospital

From the question, 72% of these animals are dogs

72% of a total of 230

Mathematically, the number of dogs are as follows;

dogs = 72% of 230

dogs = 72/100 * 230 = 165.6

since we cannot have a fractional dog, we round off to the nearest whole number which is 166 dogs

Answer:

There is no graph but the graph that would have a straight line

Answer:

Whichever line is straight and does not have x repeat itself is considered linear.

Step-by-step explanation:

A linear function can be shown by using the equation y=mx+b, in which m is the slope and b is the y-intercept. A linear function must be able to follow this formula in order to be considered linear. An exponential equation, quadratic equation, or other equation will not work.

Chances are, if the line is straight and the points plotted can be connected within a straight line and not overlap, they are a linear function.

[A function being an equation in which x does not repeat itself, therefore a vertical line up and down is not considered a linear function, however, a horizontal line is.]

Answer:

Step-by-step explanation:

The answer choices don’t make sense. The volume of a cylinder of height 45mm and radius 5mm = π5²*45 = 1125π mm³.

Three of the answer choices are larger than 1125π.

:::::

volume of one cone = πr²h* ⅓

Volume of cylinder section = πr²h

Total volume = πr²h*⅔ + πr²h = πr²h*5/3 = π5²*15*5/3 = 625π

Answer:

∠b=35

Step-by-step explanation:

Hello There!

Complementary angles add up to equal 90

so to find the measure of angle B we subtract the given angle from 90

90-55=35

so we can conclude that ∠b = 35

Answer:

50

Step-by-step explanation:

The upper left hand arc is also 130

The lower right hand arc is also x

A circle all the way around from some starting point is 360 degrees.

x + x + 130 + 130 = 360            Equation. Combine like terms.

2x + 260 = 360                         Subtract 260 from both sides

2x = 360 - 260                    

2x = 100                                    Divide by 2

x = 100/2

x = 50

Answer: Small Candle = 12, Large Candle = 16

Step-by-step explanation:

Equation is this, s+l=28 2nd equation is 4s+6l=144

now you multiply every number in the second equation by -6 since positive 6 is the second equations second constant. Now you got -6s-6l=-168 And 4s+6l=144. The -6l and positive cancel so now you got -6s + 4s = -168+144. Now you got -2s = -24. Divide them both by negative two then you get s = 12. 28 candles total - 12 = 16 so 16 large candles and 12 small. L = large candles, S = small candles.

Answer:

8 small candles

16 large candles

Step-by-step explanation:

1. Approach

Set up a system of equations to solve this problem. Call the number of small candles sold (x), and the number of large candles sold (y). Have one expression model the amount of money earned, the other model the number of candles sold. Then, solve this system of equations using the process of elimination. In the process of elimination, one multiplies one of the equations by a term such that one of the coefficients of a variable in one of the equations is the additive inverse of the corresponding variable in the other equation. This means that when one adds the two equations, one of the variables will eliminate. Then one can solve for the other variable, and finally, substitute the value of the variable that one found back into one of the equations, and solve for the value of the other variable.

2. Set up a system of equations

Use the given information to set up a system of equations to describe the amount earned, and the amount sold

x + y = 28 -> amount sold

4x + 6y = 144 -> amount earned

3. Solve the system

As explained above, the process of elimination is a method of solving a system of equations. In the process of elimination, one multiplies one of the equations by a term such that one of the coefficients of a variable in one of the equations is the additive inverse of the corresponding variable in the other equation. This means that when one adds the two equations, one of the variables will eliminate.

x + y = 28 (*-4)

4x + 6y = 144

-4x - 4y = -112

4x + 6y = 144

___________

2y = 32

/2     /2

y = 16

4. Solve to find out how much of the other candle was sold

Now back solve, substitute the found value into one of the equations, and solve to find the other value

x + y = 28

y = 16

x + 16 = 28

    -16     -16

x = 8

Starting with your given:

#cot^2(x)-csc^2(x)#

Replace #csc^2(x)# with #1+cot^2(x)#:

#cot^2(x)-(1+cot^2(x))#

#=cot^2(x)-1-cot^2(x))#
