The distance between two points is √39 One endpoint is (4,−3). It is known that the y-coordinate of the other endpoint is 2.

What is the x-coordinate of this endpoint?

Answers

Answer:

[tex](4-\sqrt{14}, 2)\text{ or } (4+\sqrt{14}, 2)[/tex]

Step-by-step explanation:

We have the two points: (4, -3) and (x, 2).

We know that the distance between them is √39.

To find our x-coordinate of the second point, we can use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

Let (4, -3) be (x₁, y₁) and let (x, 2) be (x₂, y₂). We also know that the distance d is √39. Substitute:

[tex]\sqrt{39}=\sqrt{(x-4)^2+(2-(-3))^2[/tex]

Solve for x. First, let's square both sides. This cancels out the square roots:

[tex]39=(x-4)^2+(2+3)^2[/tex]

Evaluate the second term on the right:

[tex]39=(x-4)^2+(5)^2[/tex]

Square:

[tex]39=(x-4)^2+25[/tex]

Subtract 25 from both sides:

[tex]14=(x-4)^2[/tex]

Take the square root of both sides. Since we're taking an even root, we need plus/minus. So:

[tex]x-4=\pm\sqrt{14}[/tex]

Add 4 to both sides:

[tex]x=4\pm\sqrt{14}[/tex]

Therefore, there exists two possibilities for our second point. It can either be:

[tex](4-\sqrt{14}, 2)\text{ or } (4+\sqrt{14}, 2)[/tex]

And we're done!

The shop sold 12,789 chocolate and 9,324 cookie dough cones. It sold 1078 more peanut butter cones than cookie dough cones. And 999 more vanilla than chocolate cones. What was the total number of ice cream cones sold?

Answers

Answer:

46,303

Step-by-step explanation:

12789+9324+9324+1078+12789+999= 46,303

The total number of ice-cream sold was 46,303 as the shop sold 12,789 chocolate and 9,324 cookie dough cones. It sold 1078 more peanut butter cones than cookie dough cones that means 10,402 peanut butter cones and 999 more vanilla than chocolate cones that means 13,788 vanilla cone.

What is total?

Total refers to an entire or complete amount, and the verb "to total" means to combine two numbers or to destroy something. In mathematics, you add numbers to get the total; the outcome is the total. The result of adding 8 and 8 is 16. A total is the sum of several numbers or the number of items in a group, as determined by addition or counting. Total is referred to as the total or overall sum. The final amount for dinner on a check serves as an illustration of a total.

Here,

number of chocolate cone=12,789

number of cookie dough cone=9,324

peanut butter cone=9,324+1,078=10,402

vanilla cone=12,789+999=13,788

Total sum= number of chocolate cone + number of cookie dough cone+ peanut butter cone+ vanilla cone

=12,789+9,324+10,402+13,788

=46,303 ice-cream cones

The shop sold 12,789 chocolate and 9,324 cookie dough cones, for a total of 46,303 scoops of ice cream. It sold 999 more vanilla than chocolate cones, which translates to 13,788 vanilla cones, and 1078 more peanut butter than cookie dough cones, or 10,402 peanut butter cones.

Ariana needs to rent a car while on vacation. The rental company charges $18.95, plus 16 cents for each mile driven. If Ariana only has $40 to spend on the car rental, what is the maximum number of miles she can drive?

Ariana can drive a maximum of
miles without the cost of the rental going over $40.Round your answer to the nearest mile.

Answers

Answer:

Ok simple Algebra Question:

Let "x" be the number of miles she drives.

18.95 + 0.16x = 40.00

Subtract 18.95 from both sides.

0.16x = 21.05

Divide both sides by 0.16

You get:

x = 131.5625
