What is the solution to the inequality 8(7 - x) < 64?
a. X<-1
b. x<1
C. X > -1
d. x > 1​

Answers

Answer 1

Answer:

C)  x > - 1

Step-by-step explanation:

8(7 - x) < 64

56 - 8x < 64

56 - 64 < 8x

- 8 < 8x

- 1 < x

x > - 1

Answer 2

Answer:

The answer is c, or x > -1.

Step-by-step explanation:

Problem: 8(7-x) < 64

Distributive Property - So multiply 8 by both 7 and x individually

56 - 8x < 64

Subtract 56 from both sides

-8x<8

Divide both sides by 8 and flip the sign because whenever you divide or multiply an inequality by a negative number, you flip the sign.

x>-1

what is the equation of a line that passes through the points -2 -2 and has a slope of four

Answers

Answer:

y = 4x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4, thus

y = 4x + c ← is the partial equation

To find c substitute (- 2, - 2) into the partial equation

- 2 = - 8 + c ⇒ c = - 2 + 8 = 6

y = 4x + 6 ← equation of line

On a soccer team 40% of the goal are scored by a star player on the team.If 70 goals were scored all season, how many are scored by the rest of the team? Plz help me

Answers

Answer:

42

Step-by-step explanation:

During the season, 40% of the goals are scored the by the star player.  This means that 60% of the goals are scored by everyone else.

100% - 40% = 60%

To find how many goals are scored by the rest of the team, convert the percentage to a decimal.  You then have to multiply the decimal by the total goals scored.

60% = 0.6

70 × 0.6 = 42

The rest of the team scored 42 goals.  

Answer:

42

Step-by-step explanation:

40% of 70=28

How many solutions does the equation 4x + 8 = − 2 − 2 + 5x have?

Answers

Answer:

There is one solution

Step-by-step explanation:

4x + 8 = − 2 − 2 + 5x

Combine like terms

4x+8 = -4+5x

Subtract 4x from each side

4x-4x+8 = -4+5x-4x

8 = -4+x

Add 4 to each side

8+4 = -4+4+x

12 =x

Circumference of a circle

The path or the boundary that encircles any shape is defined by its circumference. In other words, the perimeter is another name for the circumference, which makes it easier to determine how long a shape's outline is. The circle's perimeter is measured in this way. whereas the circumference of a circle determines the space it occupies. The circumference of a circle is its length when it is opened up and drawn as a straight line. Units like cm or unit m are typically used to measure it.

We take radius of the circle and pi to calculate the circumference of circle.

The formula of circumference of circle is 2πr.

R is radius of the circle and π is mathemetical constant which value approx 3.14

In the question it is given that the diameter of a wheel is 80m. So, radius is half of diameter, 40m.

So, the circumference = 2πr

                                     = 2 × 3.14 × 40 = 251.2m

Rider has to travel 251.2m to cover one complete rotation.

If a patient needs a 30-day supply of tablets four times a day, how many tablets will the patient need for discharge?

Answers

This question is incomplete

Complete Question

If a patient needs a 30-day supply of tablets and takes two tablets four times a day, how many tablets will the patient need for discharge?

Answer:

240 tablets

Step-by-step explanation:

From the question we are told the patient needs a 30 days supply of drugs.

This means the patient will be discharged after 30 days

We are told the patient takes 2 tablets , four times a day

This means

One day = 2 tablets × 4 = 8 tablets

Hence, if:

1 day = 8 tablets

30 days = unknown so we represent by Y

We cross multiply

1 × Y = 8tablets × 30days

Y = 240 tablets

Therefore, the patient would need 240 tablets for discharge.

n:

Answer:

A) Each Interior Angle = 180 degrees - (360 / number sides)

B) Each Exterior Angle = 360 / number of sides

A) = 8 * B)

8 * 360 / # sides = 180 - (360 / #sides)

We'll call # sides as "n".

2,880 / n = [ 180 - (360 / n)]

2,880 = n * [ 180 -(360 / n)]

3,240 = 180n

Which of the following represents a 1.00 M (M = mol/dm3) aqueous solution of glucose (C6H12O6)?

A. 180 g glucose per 1000 cm3 solution

B. 10.0 g glucose per 10.0 cm3 water

C. 90.0 g glucose per 500 cm3 water

D. 0.100 g glucose per cm3 solution

Answers

Answer:

Option C. 90.0 g glucose per 500 cm3 water

Step-by-step explanation:

1.00 M (mol/dm3) aqueous solution of glucose (C6H12O6) means that 1 mole of glucose is dissolved in 1dm³ (1000cm³) of water.

The concentration of a substance is defined as the mole of solute per unit volume of solvent (water) in dm³.

Option A is wrong since it state: 180g of C6H12O6 per 1000cm³ of solution. Concentration is always expressed as per 1000cm³ or dm³ of water.

For option B:

We shall determine the number of mole of C6H12O6, followed by the concentration.

This is illustrated below:

Molar mass of C6H12O6 = (12x6) + (12x1) + (16x6) = 180g/mol

Mass of C6H12O6 = 10g

Mole = Mass /Molar Mass

Mole of C6H12O6 = 10/180 = 0.056 mole.

Volume of water = 10cm³ = 10/1000 = 0.01dm³

Concentration = mole /Volume

Concentration = 0.056/0.01 = 5.6mol/dm³

Option B is wrong

For option C:

We shall determine the number of mole of C6H12O6, followed by the concentration.

This is illustrated below:

Molar mass of C6H12O6 = 180g/mol

Mass of C6H12O6 = 90g

Mole = Mass /Molar Mass

Mole of C6H12O6 = 90/180 = 0.5mole

Volume of water = 10cm³ = 500/1000 = 0.5dm³

Concentration = mole /Volume

Concentration = 0.5/0.5 = 1mol/dm³

Option C is correct.

For option D is wrong as well as it states 0.1g of C6H12O6 per cm³ of solution. Concentration is always per 1000cm³ or dm³ of water.

From the above illustrations, option C is the correct answer.
