Answer:

1. 10

2. 12

3. Sqrt 130

4. Sqrt 45

Step-by-step explanation:

To find the missing side of a right triangle, use the Pythagorean Theorem. The Pythagorean Theorem is a^2+b^2=c^2 where a and b are the legs with a being the smallest and c is the hypotenuse.

1. a=6, b=8, c=?

6^2+8^2=c^2\\36+64=c^2\\100=c^2\\10=c

2. a=5, b=?, c=13

5^2+b^2=13^2\\25+b^2=169\\169-25=b^2\\144=b^2\\12=b

3. a=7, b=9, c=?

7^2+9^2=c^2\\49+81=c^2\\130=c^2\\\sqrt{130}=c

4. a=2, b=?, c=7

2^2+b^2=7^2\\4+b^2=49\\49-4=b^2\\45=b^2\\\sqrt{45}=b

70 POINTS HELP ME URGENT SHOW YOUR WORK
Feliz [49]

Answer:

A)

x=  the number of ride tickets

y=  the total cost of admission plus how many ride tickets a person purchases

B)

y= 1.25x + 9.5

C)

It is a$1.25 per ticket for the rides at the fair, so it would be 1.25 multiplied by the amount of tickets that are purchased (x). Spencer bought 17 tickets, so 17x1.25= 21.25 and it says that he spent a total of $30.75 at the fair, so 30.75-21.25=9.5, so that means the cost of admission is $9.50.

Step-by-step explanation:

I hope this helps!

4) 27.5 m^2

5) 48 ft^2

6) 96 m^2

Step-by-step explanation:

3) 4(2x3x0.5) = 12 yd^2

4) (9x5)-(0.5)(7x5) = 27.5 m^2

5) (10x6)-(6x2) = 48 ft^2

6) 12x8 = 96 m^2

I need help with This one
balandron [24]

Answer:

1 and 2

Step-by-step explanation:

If y was 1: -2 x 1 + 18 = -2 + 18

= 16  This works

If y was 2: -2 x 2 + 18 = -4 + 18

= 14  This works

If y was 3: -2 x 3 + 18 = -6 + 18

= 12  This does not work since -2y + 18 has to be <u>greater</u> than 12.
