club's size?
members please help

Answer:

- 4, - 3, - 2, - 1, 0

Step-by-step explanation:

Given

- 2 < n + 3 < 4 ( subtract 3 from each interval )

- 5 < n < 1

This indicates that n ≠ - 5, 1 but all values in between, that is

n = - 4, - 3, - 2, - 1, 0 ← possible values of n

Answer:

Try adding the percent of 5.

Step-by-step explanation:

(5 percent off 19.00 is 18.05 The difference is 0.95)

It might be ADDING in the situation

cause 19.00 + (5percent) = 19.95

Why: I think its adding a percent of 5

Because clue content.. And the clue was (total cost with service fee)

(total) is one of the context clues for addition or adding.

and it adding service fee.

so it wants an addition of the total cost with service fee.

Answer:

1st Triangle

Step-by-step explanation:

Answer:

The answer is 36

Step-by-step explanation:

First, suppose that each square is the unit length, and from it the length of the hall can be calculated and we find that it is equal to 10, then to find the value of the other two we drop a column of the vertex of the triangle on the base and find that its length is 12 units and it divides the base into two equal halves, so we determine that each side equals 13 units using Pythagoras and it will be The lengths of the sides of the triangle are 10, 13, 13

Then the perimeter is

[tex]10 + 13 + 13 = 36[/tex]

Answer:

the total amount collected is 2,665

Step-by-step explanation:

The computation of the total amount collected is shown below:

= price × number of tickets sold × price + number of tickets sold × price + price

= 14 × 15 × 10 + 56 × 10 + 5

= 2,100 + 560 + 5

= 2,665

Hence, the total amount collected is 2,665

Answer:

The quadratic equations and their solutions are;

9 ± √33 /4 = 2x² - 9x + 6.

4 ± √6 /2 = 2x² - 8x + 5.

9 ± √89 /4 = 2x² - 9x - 1.

4 ± √22 /2 = 2x² - 8x - 3.

Explanation:

Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.

We have to solve all of the five equations to be able to match the equations with their solutions.

2x² - 8x + 5, here a = 2, b = -8, c = 5.                                                  x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4.     24 can also be written as 4 × 6 and √4 = 2. So                                                                                     x = 8 ± 2√6 / 2×2= 4±√6/2.

2x² - 10x + 3, here a = 2, b = -10, c = 3.                                                   x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So                                                                              x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.

2x² - 8x - 3, here a = 2, b = -8, c = -3.                                                    x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4.     88 can also be written as 4 × 22 and √4 = 2. So                                                                             x = 8 ± 2√22 / 2×2 = 4± √22/2.

2x² - 9x - 1, here a = 2, b = -9, c = -1.                                                     x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4.                                          x = 9 ± √89 / 4.

2x² - 9x + 6, here a = 2, b = -9, c = 6.                                                    x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4.                                                                             x = 9 ± √33 / 4 .

Answer:

b. 36

Step-by-step explanation:

Answer:

length is 10, width is 7

Step-by-step explanation:

Area of a rectangle = length * width = lw

Area is known to be 70

length = twice width - 4 = 2w-4 = l

width=w

so A = lw = (2w-4)w = 70

(2w-4)w=70

2w^2-4w=70

2w^2-4w-70=0, divide by 2

w^2 - 2w - 35 = 0, not sure how your class solves these, I see visually

(w-7)(w+5)=0

w=7 or w=-5, -5 makes no sense in the real world (negative length), so w=7

l = 2w-4 = 2(7)-4 = 14-4 = 10

Answer:

Step-by-step explanation:

-2x < 10

divide both sides by -2

x > -5

note that the direction of the inequality changes

Answer:

28°

Step-by-step explanation:

Let's take 'x' as the number of how much degrees it dropped. So this is how the equation will look like:

-2 - x = -30

It is '-x' since the temperature 'decreased', so you must a subtract.

Take -30 to the other side and substitute it with '-x'. Since both the terms are shifted, -30 will be +30 and -x will be +x (which is equivalent to x).

x = -2 + 30

x = 28°

∴ There was a 28° drop.

Answer:

9240 feet

Step-by-step explanation:

Petrov ran 7 laps around a track.Each lap around the track is a distance of 1/4 mile.

Step 1

The total distance Petrov ran in miles is calculated as:

1 lap = 1/4 mile

7 laps = x mile

Cross Multiply

x = 7 × 1/4 mile

x = 1.75 miles

Step 2

What is the total distance Petrov ran in feet?

1 mile = 5280 feet

1.75 miles = x

Cross Multiply

x = 1.75 × 5280 feet

x = 9240 feet

Therefore, the total distance Petrov ran in feet is 9240 feet

Answer:

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators

36/x=8/7

x times 36/x=x times 8/7

Cancel multiplied terms that are in the denominator

cancel both x’s for you should have 36=x times 8/7

Combine multiplied terms into a single fraction

36=8x/7

Multiply all terms by the same value to eliminate fraction denominators

36=8x/7 so you multiply 7 times 36=7 times 8x/7

so you simplify so you get 252=8x

then you Divide both sides of the equation by the same term

252=8x     252/8=8x/8 so you get 63/2

so your final answer is x=63/2

Answer:

If Ron works 8 hours a day and get's paid $15 an hour

for 5 days a week and works for 12 weeks

1 hour = $15

8 hours = $120

So Ron get's paid $120 a day

So if he works 5 days a week then

120 x 5 = $600

Ron get's paid $600 a week

So if Ron works for 12 weeks then

600 x 12 = $7,200

Ron's gross pay is $7,200
