First add them all together = $13,137.67. Then divide that by how many addens you have (in this case 5) and that gives you $2,627.53 :)

A square has perimeter 12x. Find an expression, in terms of x, for the area of the square. Give your answer in its simplest form.

Answers

Answer:

Step-by-step explanation:

A square has 4 sides

$(12x)/(4)$ = 3x

Area is length times width, but we would square it in this case.

3x * 3x = $(3x)^(2)$ = 9 $x^(2)$

A new car sells for $25,000. The value of the car decreases by 17% annually. After how many years will the car be worth less than $10,000. Choose the best answer. (4.2)a. after 4 years

b. after 6 years

c. after 8 years

d. not enough information

Answers

Let a = car's age in years and v = value of car.

v = 25000(1 - 0.17)^a

v = 25000(0.83)^a

We need to find a.

Let v = 10,000

10,000 = 25000(0.83)^a

The value of a is about 4.91758.

Round off to the nearest whole number we get 5.

Answer is after more than 4 years but less than 6 and 8.

Two groups separately performed an experiment by tossing a coin in the air. Group A performed 50 trials and group B performed 100 trials. Each group recorded the results in the table below:Group Heads Tails
A 30 20
B 52 48

What conclusion can be drawn about the number of trials and the probability of the coin landing on heads or tails?

Answers

Theoretical probability;
Head = 1/2 or 50%
Tail = 1/2 or 50%

Group Heads Tails Total
A 30 20 50
B 52 48 100

Experimental probability:
Group A:
Heads : 30/50 = 60%
Tails: 20/50 = 40%

Group B:
Head: 52/100 = 52%
Tails: 48/100 = 48%

Experimental probabilities of Group B is closer to the theoretical probabilities.

-6x+11 = 7-10x show all work

Answers

Answer:

Step-by-step explanation:

collect like terms ( when a negative sign crosses the equality sign it becomes positive and vice versa)

-6x + 10x=7-11

4x=-4

divide both sides by the coefficient of x

4x/4=-4/4

x=-1

Easy

-6x + 11 = 7 - 10x
Substract 11 from both sides=
-6x = -4 - 10x
Add 10x to both sides
4x = 4
Now divide both sides by the same factor
Answer is x = -1

Xanthe is a client that Josie trains. Xanthe’s MHR is 190 beats per minute. Her target heart rate is 70% of her MHR. What is Xanthe’s target heart rate?

Answers

The answer is 133 beats per minute.

To calculate this, we will use proportion.
If 190 beats per minute are 100%, how many beats per minute are 70%:
190 bpm : 100% = x : 70%
$(190 bpm)/(100) = (x)/(70)$
$(70 * 190bpm)/(100) = x$
$x = 133 bpm$

Thus, Xanthe's target heart rate is 133 beats per minute.

Answer:

133
