Its A because 5 squared = 25 and 12 squared = 144 so 144+ 25= 169.
169=13 squared so its 13 or A

s.a: A

You're trying to find the longest side of a right triangle, also known as the hypotenuse. The formula used is called the Pythagorean Theorem.
a^2+b^2=c^2
5^2+12^2=c^2
25+144=c^2
169=c^2
13=c

Solve using a system of equations. Tickets to a local movie were sold at $6.00 for adults and $4.50 for students. If 110 tickets

Marrrta [24]

Answer:

The number of adults tickets is 80 and the number of students tickets is 30

Step-by-step explanation:

Given as :

The tickets price for adults = $6.00

The tickets price for students = $4.50

Total number tickets were sold = 110

Total Price of 110 tickets = $615.00

Now,

Let The number of adults tickets sold = A

The number of students tickets sold = S

So, according to question

A + S = 110

And 6 A + 4.5 S = 615

Or, 6 A + 6 S = 660 .....1

6 A + 4.5 S = 615 ......2

Solving the equations

( 6 A + 6 S ) - ( 6 A + 4.5 S ) = 660 - 615

Or, ( 6 A - 6 A ) ( 6 S - 4.5 S ) = 45

or, ( 6 S - 4.5 S ) = 45

or, 1.5 S = 45

∴ S = $\frac{45}{1.5}$

I,e S = 30

Put the value of S in eq 1

So, 6 A + 6 × 30 = 660

Or, 6 A = 660 - 180

Or 6 A = 480

∴ A = $\frac{480}{6}$

I.e A = 80

Hence The number of adults tickets is 80 and the number of students tickets is 30 . Answer

Malcolm and Theo's families are both traveling to the same vacation resort.

snow_tiger [21]

Answer:

Malcom's family travel 15 miles per hour faster than Theo's

Step-by-step explanation:

<em>See attachment for complete question</em>

Given

Malcom's Family:

$d = 65t$

To determine the equation of Theo's family, we refer to the attached graph.

From the graph:

$t = 1; d = 50$

$t = 2; d = 100$

First, we determine the slope, m:

$m = \frac{d_2 - d_1}{t_2 - t_1}$

$m = \frac{100 - 50}{2- 1}$

$m = \frac{50}{1}$

$m = 50$

Next, we determine equation for Theo's family using:

$d - d_1 = m(t - t_1)$

$d - 50 =50(t - 1)$

$d - 50 =50t - 50$

Add 50 to both sides

$d - 50 +50=50t - 50 + 50$

$d =50t$

So, we have the following:

$d = 65t$ --- For Malcom's family

This implies that Malcom's family travel at 65 miles per hour

$d =50t$ --- For Theo's family

This implies that Theo's family travel at 50 miles per hour

The difference between this rates is:

$Rate = 65t - 50t$

$Rate = 15t$

<em>Which implies that Malcom's family travel 15 miles per hour faster than Theo's</em>

Mike and Thomas were making Lego towers. Mike stacked 249 Legos for his tower. Thomas had stacked twice as much as Mike. How man

FrozenT [24]

Answer:

498

Step-by-step explanation:

So,if mike stacked 249 legos and thomas did twice as much that means x2 so if you do 249 x2 you get 498.
