Answer:

Let s and l be the price of small and large dishes. The first equation is

While the second equation is

(I assume that you meant "4 small dishes and 3 large dishes")

If we multiply the first equation by 4 and the second by 3 we have

Subtract the two equation and you have

Substitute this value in one of the equation to derive

So, one small dish costs 2.9 and one large dish costs 3.9. This means that 2 small and 4 large dishes cost

We have been given that Fernando bought a jacket for $185 and sold it for 1 1/2 times what he paid.

Let us find selling price of jacket as:

[tex]\text{Selling price of Fernando's jacket}=\$185\times 1\frac{1}{2}[/tex]

[tex]\text{Selling price of Fernando's jacket}=\$185\times \frac{3}{2}[/tex]

[tex]\text{Selling price of Fernando's jacket}=\$277.5[/tex]

We have been given that Marisol spent 1/5 as much as Fernando on the same jacket.

[tex]\text{Cost of Marisol's jacket}=\$185\times \frac{1}{5}[/tex]

[tex]\text{Cost of Marisol's jacket}=\$37[/tex]

We are also told that Marisol sold the jacket for 1/2 as much as Fernando did.

[tex]\text{Selling price of Marisol's jacket}=\frac{\$277.5}{2}[/tex]

[tex]\text{Selling price of Marisol's jacket}=\$138.75[/tex]

The amount of money earned by Marisol would be selling price of jacket minus cost.

[tex]\text{Amount of money earned by Marisol}=\$138.75-\$37[/tex]

[tex]\text{Amount of money earned by Marisol}=\$101.75[/tex]

Therefore, Marisol made $101.75.

So, to find this answer, we want to use Pythagorean Theorem!

The formula for this theorem is: a²+b²=c².

· It's important to note that c² is always your hypotenuse, while a and b are your legs.

So, all we need to do is (1) plug in our values, (2) square them, (3) isolate them, and (4) find the square root of our final number!  

--------------------------------------------------------------------------------------------------------------

14²+14²=c²

14² = 196

We want to isolate our C, but we can't do that with the squared symbol, so in order to remove a squared symbol, we need to square root both sides.

196 = c²

√196 = 14

C = 14

Answer:

x>-8

Step-by-step explanation:

When you multiply (or divide) both sides of an inequality by a negative number (in this case -1), you need to flip the inequality symbol. For instance in this case, -x<8 is the same as x>-8. This is because you know that if -x is less than 8, if x is less than -8 then the inequality wouldn't be true any longer. This can be demonstrated with an example: Say that x is -10. -(-10) is 10, and no longer smaller than 8. Therefore, x>-8. Hope this helps!

Let x represent number of massages and y represent number of pedicure + 90-minute massage packages.

We have been given that a spa charges $125 for a one hour massage, so amount earned from x massages would be [tex]125x[/tex].

The spa charges $250 for a pedicure + 90-minute massage package, so amount earned from y pedicure + 90-minute massages will be [tex]250y[/tex].

We have been given that one day the spa had 27 customers. We can represent this information in an equation as:

[tex]x+y=27...(1)[/tex]

[tex]y=27-x...(1)[/tex]

Since spa made $5,250, so amount earned from both massages would be equal to 5,250. We can represent this information in an equation as:

[tex]125x+250y=5250...(2)[/tex]

Upon substituting equation (1) in equation (2), we will get:

[tex]125x+250(27-x)=5250[/tex]

Let us solve for x.

[tex]125x+6750-250x=5250[/tex]

[tex]-125x+6750=5250[/tex]

[tex]-125x+6750-6750=5250-6750[/tex]

[tex]-125x=-1500[/tex]

[tex]\frac{-125x}{-125}=\frac{-1500}{-125}[/tex]

[tex]x=12[/tex]

Upon substituting [tex]x=12[/tex] in equation (1), we will get:

[tex]y=27-12=15[/tex]

Therefore, the spa performed 12 one hour massages and 15 pedicure + 90-minute massage  packages that is [tex](12,15)[/tex].

The lowest temperature in January is -10°C.

Integers come in three types:

Given:

The lowest temperature in January was less than−6°.

as, we know in integers the smaller the number the grater its value.

such as -100 < (-1)

So, -6 > -10

and, -6 < 0

and, -6 < -5

and, -6 < -2.

Thus, the lowest temperature is -10°C.

Final answer:

The lowest temperature in January can be any temperature that is less than -6°.

Explanation:

The question asks for the lowest temperature in January, given that it is less than -6°. Since the question does not provide a specific range, any temperature that is less than -6° can be considered the lowest temperature in January. For example, -10°, -15°, or -20° can all qualify as the lowest temperature in January.

Step-by-step explanation:

Answer:

A. {(9,3),(5,16),(6,8),(9,10),(11,13),(1,7)}

Explanation:

The first option is not a function because a single x-value cannot pair up to more than one y-value. We can see this occur in the ordered pairs below.

(9,3),(9,10)

Answer:

(3,0) and (0,6)

Step-by-step explanation:

(x,y) is the only way to make ordered pair.

The x was a 3 so you could cross out the first and last because they put the 3 in the y spot. When is should be (3,0).

Then the y was 6 and that I would be (0,6) so the third would also be crossed out because they put the 6 in the y spot.

So the answer is (3,0) and (0,6).

The temperature in the greenhouse before the heater stopped working was at least 71 degrees Fahrenheit, based on the information that the temperature dropped 6 degrees but remained at least 65 degrees.

As the temperature dropped 6 degrees and was still at least 65 degrees when the heater was fixed, we can set up a simple inequality to represent this situation:

Let T represent the temperature before the heater stopped working. After the heater stopped working and the temperature dropped by 6 degrees, the new temperature would be T - 6. According to the provided information, this new temperature was still at least 65 degrees, which gives us the inequality:

T − 6 ≥ 65

Adding 6 to both sides of the inequality, we find:

T ≥ 71

This means that the temperature in the greenhouse before the heater stopped working was at least 71 degrees.  

Answer:

The other end of the rope was not tied to anything

Step-by-step explanation:

The dog was tied to a rope of 15 feet  long and the bone was 30 feet away from where he was tied. The rope used to tie the dog is 15 ft long . But the other end of the rope wasn't tied to anything, this simply means the dog can easily approach and get the bone 30 ft away from where it was tied.

The other end of the rope was not tied to anything . This implies that the dog can simply reach the bone without breaking a sweat. The 15 feet rope was only tied to the dog , so it does not stop the dog from reaching a bone that is 30 ft away.

Final answer:

The radius of the base of the vase is 19.5 cm.

Explanation:

To find the radius of the base of the vase, we can use the formula for pressure: pressure = force/area. In this case, the force exerted by the vase on the table is 15 N and the pressure is 700 N/m². Let's assume the base of the vase is a circle. The area of a circle is given by the formula A = π r², where r is the radius of the circle.

So, we can rearrange the formula for pressure to solve for the radius:

r = √(force/pressure) = √(15 N / 700 N/m²) = 0.195 meters.

To convert the radius from meters to centimeters, we multiply by 100: 0.195 meters * 100 = 19.5 centimeters. Hence, the radius of the base of the vase is 19.5 cm.

Final answer:

By applying the pressure formula and solving for the radius, the calculated radius of the base of the vase comes out to be approximately 8.26 cm to two decimal places.

Explanation:

To find the radius of the base of the vase, we need to use the formula for pressure, which is pressure (P) equals force (F) divided by area (A). The formula can be expressed as:

P = F / A

We have been given the pressure and the force, and the area of a circle is equal to π × radius^2 (πr^2). By substituting the known values into the pressure formula and solving for the radius, we get:

700 N/m2 = 15 N / (πr^2)

r^2 = 15 N / (700 N/m^2 × π)

r = √(15 / (700 × π))

Now, calculate the numerical value of the radius:

r = √(15 / (700 × 3.14159))

r ≈ √(0.0068194)

r ≈ 0.082595 cm

To present our answer in centimeters to two decimal places:

r ≈ 8.26 cm

Answer:

x=2

Step-by-step explanation:

Let's solve your equation step-by-step.

4(2x−3)=4

Step 1: Simplify both sides of the equation.

4(2x−3)=4

(4)(2x)+(4)(−3)=4(Distribute)

8x+−12=4

8x−12=4

Step 2: Add 12 to both sides.

8x−12+12=4+12

8x=16

Step 3: Divide both sides by 8.

8x /8 = 16 /8

x=2

Answer:

x = 2

Step-by-step explanation:

4(2x-3) = 4

⇔

4 × (2x-3) = 4 × 1

⇔

(2x-3) = 1 (divide both sides by 4)

⇔

2x = 1 + 3 (Move 3 to the right hand side)

⇔

2x = 4

⇔

x = 4/2

⇔

x = 2

Final answer:

The mean weight of Niels' cargo loads in kilograms is 18,900 kg and the standard deviation is 675 kg, making the correct answer A.

Explanation:

To convert Niels' cargo loads from pounds to kilograms, we multiply the mean weight and the standard deviation by the conversion factor of 0.45 kg/lb.

The mean weight in kilograms is calculated as follows:

Mean (kg) = 42,000 lb × 0.45 kg/lb = 18,900 kg

The standard deviation in kilograms is calculated as follows:

Standard deviation (kg) = 1,500 lb × 0.45 kg/lb = 675 kg

Therefore, the correct answer is A: Mean: 18,900 kg, Standard deviation: 675 kg.
