You are 4 years less than three times the age of your sister. Let s be the age (in years) of your sister. Write an expression for your age in terms of your sister's age.

An expression for your age is

Answer:

One eighth

Step-by-step explanation:

By multiplying each fraction by 100, you can get the percentage.

(1/8) x 100 = 12.5

(5/4) x 100 = 125

(16/25) x 100 = 64

Answer:

A

Step-by-step explanation:

100 / 12,5 = 8

12,5% = 1/8

Answer:

probably is around like 7x- somthing

Step-by-step explanation:

Let m = man's age right now

d = daughter's age right now

m-2 = 6(d-2)  =>  m = 6d -12 +2 = 6d-10

m+18 = 2(d+18)   =>   m = 2d+36-18 = 2d+18

6d-10 = 2d+18

4d = 28

d = 7

m = 32

Answer:

5:3.

Step-by-step explanation:

Riley can dribble a basketball 50 times in 1/2 minute with her right hand and 30 times in 1/2 minute with her left hand.

Rate of her right hand is : [tex]\dfrac{50}{(1/2)}=100\ \text{per minute}[/tex]

Rate of her left hand is : [tex]\dfrac{30}{(1/2)}=60\ \text{per minute}[/tex]

Ratio of her right hand to her left hand dribbling rate : [tex]\dfrac{100}{60}=\dfrac{5}{3}[/tex]

So, the required ratio is 5:3.

Answer:

(2x + 5)

Step-by-step explanation:

2(x + 1) + 6x = 4(2x + 5) + 2

2x + 2 + 6x = 8x + 20 + 2

8x + 2 = 8x + 22

Because both sides are 8x it will have no solution      

Second one is "all of these are correct"

Answer:

-150

Step-by-step explanation:

The function f is defined by f(x )=150÷x −z , where z is constant. Find z if the value of f at x = 1 5 is equal to 250.

Given the function;

f(x )=150÷x −z

This can also be written as;

f(x )=150/x −z

If f(1.5) = 250, hence;

at x = 1.5, f(x) = 250

Substitute;

250 = 150/1.5 - z

250 = 100 - z

z = 100 - 250

z = -150

Hence the value of z is -150

Answer:

Mode

Step-by-step explanation:

29 occurs 3 times

Step-by-step explanation:

MEAN

add up all the numbers, then divide by how many numbers there are.

26+29+29+17+33+24+32+24+21+29/10

264/10

132/10 or 26.4

RANGE

The Range is the difference between the lowest and highest values.

lowest value: 17

highest value: 33

33-17= 16

MEDIAN

Arrange your number in numerical order:

17, 21, 24, 26, 29, 29, 29, 32, 33

Count how many numbers you have: 10

Since it's an even number divide 10 by 2: 5

Go to the number in that position and average it with the number in the next higher position to get the median.

5th position: 26

6th position: 29

26+29/ 2= 27.5

Therefore, the median is 27.5

MODE

To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.

17, 21, 24, 24, 26, 29, 29, 29, 32, 33

Therefore, thee mode is 29

Answer:

80,94º

Step-by-step explanation:

What I've done is, first draw a triangle with a 90º angle and write down the height (324m) and the tourist's distance (100m).

So I calculated the tangent of the angle of the tourist.

The formula is tan=Oposite side/adjacent

[tex]tan=\frac{opposite side}{adjacent}[/tex]

[tex]tan=\frac{324}{100} =3.24[/tex]

And now with your calculator you press "shift" and "tan". Then introduce 3,24 and it will give you the result (80,94º).

I hope it helped.

Answer:

16 years old

Step-by-step explanation:

Let's use the letters s, b, and c for Sushil, Brian, and Caroline's ages. Sushil is the oldest, followed by Brian, and then Caroline, the youngest. From the problem description, we can set up three equations:

s = b + 6 (Sushil is 6 years older than Brian)

c = b - 5 (Caroline is 5 years younger than Brian)

s + b + c = 64 (The total of their ages is 64)

Since s and c are already in terms of b, we can substitute them into the last equation and solve to find Brian's age:

(b + 6) + b + (b - 5) = 64

3b + 1 = 64

3b = 63

b = 21

Now that we know Brian's age, we can simply subtract 5 to find Caroline's:

c = b - 5 = 21 - 5 = 16 years old.

2. The "Part B" plan chosen has a y-intercept (b) of 24, so is not direct variation. Here, that qualifies it as "partial variation."

__

3. The lowest rate by far for 600 minutes is offered by Public Mobile (plan 6). That is the same as our hypothesis.

__

4. The highest rate of change (m) is that for Plan 3, Telus (prepaid). Its cost of $0.35 per minute is higher than that for any other plan.

The plan with the lowest slope (m) is Plan 6, Public Mobile, which has zero slope.

__

5. A graph of all the plans is shown in the attachment. For any time over 140 minutes, Plan 6, Public Mobile, is the lowest cost.

__

6. On the graph, the purple line (Rodgers MY5) plan becomes lower cost for more than 200 minutes. Below that time, the green line (Telus prepaid) is lower cost.

__

7. Plans 1, 2, 3 have no cost for zero minutes, so they are all examples of direct variation.

  choice (and cost and features) of compatible phones

Answer: 64

Step-by-step explanation:

To score an average of 60 in the three tests, the total score of the test should be: = 60 × 3 = 180

Since the student already has scores of 52 and 64, the score in the third test will be:

= 180 - (52 + 64)

= 180 - 116

= 64
