Can somebody please help me with this math question please

Mathematics
1 answer:
kondaur [170]2 years ago

Answer:

Step-by-step explanation:

isosceles triangles are ones that have two equal sides and angles. this would mean that ab is equal to bc. then you substitute the values in for AB=BC, 3x-4=5x-10. you bring the variables to one side and you flip everything which is then 2x=6 and then divide by 2. this would be x=3. then you have to figure out the AB. 3(3)-4=5. then you can always check for BC, 5(3)-10=5. and they are equal! hope i helped!

EleoNora [17]

Answer:

I believe there are 70 students in the theater!

Step-by-step explanation:

In the ratio 2:3 going to 28:? there is a pattern. You multiply 2 by 14 to get to 28, so if you multiply 3 by 14 you get 42. Add 42 to 28 for the total amount of students in class!

Have a nice night!

Rama09 [41]
If you would like to know how many hours will Lena need to work before she can afford to buy the computer, you can calculate this using the following steps:

$900 - $473 = $427

$427 / $7 = 61 hours of yard work

Result: Lena will need to work 61 hours before she can afford to buy the computer.

We will use the property :

sum of interior angles on same side of transversal =180

(8x-14) + (2x+54)=180

10x+40=180

10x=140

x=14

The cost of fighting crime in a country increased significantly during the period 1982–1999. Total spending on police, courts, a
Mice21 [21]

Answer:

t→+[infinity] [ P ( t ) ] = $62.957 billion

t→+[infinity] [ f ( t ) ] = $143.214 billion

Step-by-step explanation:

Given:

- Total spending on police, courts, and prisons in the period 1982–1999 could be approximated, respectively,

                         P(t) = 1.743*t + 29.84 billion dollars (2 ≤ t ≤ 19)

                         C(t) = 1.096*t + 10.65 billion dollars (2 ≤ t ≤ 19)

                          J(t) = 1.917*t + 12.36 billion dollars (2 ≤ t ≤ 19)

Find:

- Compute lim t→+[infinity] for:

   P ( t ) and P ( t ) + C ( t ) + J ( t )

Solution:

- The limit as t→+[infinity] for the above three function can be accounted for by considering the domain of each function.

- All functions : P ( t ) , C ( t ) , J ( t ) have the domain 2 ≤ t ≤ 19:

- So in other words, lim t→+[infinity] = lim t→19

- The limits are as follows:

            lim t→19 [ P ( 19 ) ] = 1.743*19 + 29.84 = $62.957 billion

- The function f ( t ) is as follows:

            f( t ) = P ( t ) + C ( t ) + J ( t ) = 4.756*t + 52.85 billion dollars

            lim t→19 [ f ( 19 ) ] = 4.756*19 + 52.85 = $143.214 billion
