Pythagorean theorem
a^2 + b^2 = c^2
Squared of the smaller two sides is equal to the squared largest side
a = 6, c = 14
6^2 + b^2 = 14^2
36 + b^2 = 196
b^2 = 160
b = squareroot of 160

We could solve problems like these by plugging in values

Let’s start with A

y = 94x

Let’s use 5, 15, 25 from the table

94(5) = 470
94(15) = 1410
94(25) = 2350

Next, B

y = 5x

5(5) = 25

This is wrong

Next, C

y = x + 470

Let’s try 5

475 = 5 + 470

Close, but wrong

Next, D

10 = 5 + 5

This is wrong, so the answer is A.
the answer is y=94x. pls give brainliest

Answer:

3H - 2 ≤ 14 I believe.

If i'm wrong forgive me

Answer:

G: 3h+2[tex]\leq \\[/tex]14

Step-by-step explanation:

He could've spent 14 dollars, or less, so the sign is the less than, equal to sign. The 3h represents the cost of hot dogs times the number of hot dogs. The represents the cost of the water bottle. It is addition because he purchased both the water bottle and hot dogs.

A picnic basket was marked up 95% from an original cost of $9.57. Last Friday, Rosanne bought the picnic basket and paid an additional 8% in sales tax. What was her total cost?

Answers

Answer: $10.60

Step-by-step explanation:

Turn 95% into a decimal then add $9.57, then turn 8% into a decimal then add all of the numbers together.

I'm not sure if this is right, I did it on my own.

The total cost to be paid is $20.15

What is Percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

Original cost =  $9.57

Markup= 95%

So, the new cost of the basket

=95/100 x 9.57

=0.95 x 9.57

=$9.0915

Thus, the cost of the basket is

= 9.57+9.0915

=18.66

Also, the sales tax is 8%

=8/100 x 18.66

=0.08 x 18.66

=1.4928

Therefore, the total amount to be paid is

=18.66+1.4928

=$20.15

THANK YOU............. Pls see to my request

Answer:

9 3/2

Step-by-step explanation:

substitute the given value of X into the equation 2y=X-6

2y=9-6

solve for y

y=3/2

The possible ordered pair of the system is the ordered pair (x,y)

(x,y)=(9, 3/2)

check the given ordered given pair is the system of equations

2 ×3/2=9-6

simplify the equality

9=9

3=3

since all the equalities are true,the ordered pair is the solution of the system

(x,y) =(9 3/2)

Answer:

F

Step-by-step explanation:

So lets use the process of elimantion to find the answer.

Firs off, we can tell that this is a greater/less than or equal to inequlaity, since there is a inclosed circle, not a open one. So this leaves the top left answer and bottem right answer.

Now, we can see that the graph is from 0-15. X is at 7.

This means its x+8, because the x would be smaller, or possibly even negatibe on this graph.

My theory that can better support my annwer is if we solve for  x:

x+8=15

We can subtract 8 from both sides:

x=7

And as we can see on the inequality, x is at 7 in the graph.

Hope this makes sense and helps!
