what is the diameter of the circle: x^2+y^2=16 ?
Answer:
The diameter of this circle is equal to 8
Step-by-step explanation:
The standard form of a circle is equal to x^2 + y^2 = r^2. As this equation shows x^2 + y^2 = 16, all we have to do is find the square root of 16, which is 4. This means that 4 is the radius of the circle and that 2 * 4 = 8, which is the diameter of the circle.
Because of this, the diameter of this circle is equal to 8.
A walker on a trail travels along the path described by the parametric equations
x1 (t) = 80 - 0.8 t
y1 (t) = 4t
A cub leaves another area of the trail to the west and travels along the path described by the parametric equations
x2 (t) = 0.2t
y2 (t) = 40 + 0.6 t
a. do the pathways of the walker and cub intersect?
b. do the walker and cub collide?
Answer:
no,the pathway of the walker and cub don't intersect

A basket of snacks contains 8 packs of oreos, 2 bags of chips, 6 packs of gummies, and 4 granola bars. Bill randomly choses 2 snacks. What is the probability a granola bar is chosen one choice after the other without replacing the first bar? {PLZZZZ HELP}
Answer:
There is a 3/95 probability that a granola bar is chosen one choice after the other without replacement.
Step-by-step explanation:
The probability of choosing a granola bar without replacing the first bar is 4/20, or 1/5. 4 represents the number of granola bars, and 20 represents the total snacks. Then there are 19 snacks and 3 granola bars which represents the 3/19 chance of getting a granola bar the second time without replacing it.
To find the probability of both of those events happening, multiply them.
(1/5) * (3/19) = 3/95.

the worthington family is applying for a loan to purchase a new home.In order to qualify they must have a net worth greater than 100,000. based on the info given what is the worthing family's net worth will they qualify for the loan
Answer:
I guess please finish the question or this is the numbers I had.
Step-by-step explanation:
Mr. Worthington is a dentist, so he has $85,400 in student loans to pay off. Mrs. Worthington earns $42,500 per year at her job. The Worthington family has a savings account with a balance of $18,800.They own two vehicles that are worth a combined total of $64,600.Mrs. Worthington owns an antique necklace valued at $6,200.The Worthingtons have been saving for their children's college fund. currently has a balance of $24,700.Worthington family would not be able to apply for the loan to purchase a new home because their net worth is less than $100,000
How to determine the family's networth?The given parameters are:
Student loan = $85,400
Earnings = $42,500 per year
Savings account balance = $18,800.
Vehicles worth = $64,600.
Necklace value = $6,200.
College fund balance = $24,700
The net worth is the sum of the family's earnings, account balance minus the loans.
So, we have:
Networth = $42,500 + $18,800 + $64,600 + $6,200 + $24,700 - $85,400
Evaluate the sum and the difference
Networth = $71,400
The above means that the Worthington family would not be able to apply for the loan

Ariel made cupcakes to sell. 2/3 of them were chocolate chip,25% of the reminder was strawberry and the rest were 90 vanilla cupcakes. a) How many cupcakes were chocolate chip ? b) How many cupcakes were strawberry?
Answer:
Let x be the total number of cupcakes.
Chocolate chips =
[tex] \frac{2}{3} x[/tex]
Strawberry =
[tex] \frac{1}{4} \times \frac{1}{3} \\ = \frac{1}{12} x[/tex]
Vanilla =
[tex]x - \frac{2}{3} x - \frac{1}{12}x \\ = \frac{1}{3} x - \frac{1}{12} x \\ = \frac{1}{4} x[/tex]
given
[tex] \frac{1}{4} x = 90[/tex]
[tex]x = 90 \div \frac{1}{4} \\ = 90 \times 4 \\ = 360[/tex]
a)Number of Chocolate chip Cupcakes =
[tex] \frac{2}{3} \times 360 \\ = 240[/tex]
b)Number of Strawberry cupcakes =
[tex] \frac{1}{12} \times 360 \\ = 30[/tex]
