To make sure we don't have negatives under the square root, we specify that $x \ge 0$ (x is greater than or equal to 0). We'll use this fact later on

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

Start with the given inequality $\sqrt{x} \le 7$ and square both sides to get $x \le 49$ . Couple this with the fact that $x \ge 0$ means we have this compound inequality $0 \le x \le 49$

What does this mean? It means that we can pick any value from 0 to 49 (including both endpoints) and it will be a solution to the inequality. This applies to the values 49, 48 and 44

Answer: The correct statements are 'The equation 2n = p should be 2p = n' , 'The actual cost of the onions is $3.00 per pound' and 'Potatoes cost $1.50 per pound.'

Step-by-step explanation:

Here, p represents cost of one potato and n represents the cost of one onion.

And, According to the question, He purchases 6 pounds of potatoes, p, and 3 pounds of onions, n, for $18.

Therefore, 6p +3n = 18 ------(1)

And, Onions cost twice as much as potatoes.

Therefore, n= 2p ---------(2)

Putting the values of n from 2) in equation 1),

we get, 6p+3(2p)=18

⇒6p+6p=18 ⇒ 12p =18 ⇒ p = 1.5 dollar.

Thus cost of one potato= $1.5

And cost of one onion = $ 2× 1.5= $ 3.00

Thus with help of above explanation we can say that Options first, third and fifth are correct.

You have a one-year debt and you need to pay it off the ereganal price for he year was 2,000 dollers but you've waited so long t

s2008m [1.1K]

Answer:

$1400

Step-by-step explanation:

Assuming that you would pay off the debt now and not wait any longer than to calculate how much more money you need you simply need to subtract the $1000 that you have from the total which is $2400.

$2400 - $1000 = $1400

Finally, we can see that you need an extra $1400 in order to finish paying off the debt. Unless you wait more time and the overall debt owed rises some more.

The scale of a map is 1:50000. A lake on the map is 6.16cm². find the actual area of the lake in hectares.

Mamont248 [21]

Answer:

1.54 [km²].

Step-by-step explanation:

1) the given scale is for linear functions, the given area of the lake is quadratic function. According to this

2) actual area = given area *50000 *50000;

3) the given area=0.000616 [m²],

the actual area=0.000616*50000*50000=1540000 [m²] or 1.54 [km²].

The annual average temperature of a location depends in part on its distance from the equator. The latitude at the

olasank [31]

The meaning of the constant is the average temperature at the equator statement (A) is correct.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

We have a line of best fit for the data:

y = 90 - z

Here, x is measured in degrees of latitude and y is measured in degrees of Fahrenheit.

When z = 0

y = 90

Which shows the average temperature at the equator.

Thus, the meaning of the constant is the average temperature at the equator statement (A) is correct.
