# Quadrilateral Practice Test, I’ll give brainliest to the correct answer with explanation

## Answers

Answer 1
Answer:

Answer:

120 Degrees

Step-by-step explanation:

Angle T and R are vertical angles meaning they are equal so combine the equations: 31x - 4 = 29x + 4, then solve using inverse operations

subtract 31x from both sides to get -4 = -2x + 4

Then subtract 4 from both sides to get -8 = -2x, now that we have isolated the variable we have to divide by -2 on both sides getting us x = 4, then plug in the four to the equation for angle R getting you 29 times 4 which equals 116 + 4 = 120

Answer:

145.3 square inches

Step-by-step explanation:

The lateral area of the cylinder is given by ...

LA = 2πrh

LA = 2π(2.5 in)(9.25 in) = 46.25π in²

LA ≈ 145.3 in²

About 145.3 square inches of paper is used for the label.

6 students share 4 bagels equally. How many pieces does each person get? (p.s thanks to everyone who answers)

### Answers

Solution:

we are given that

6 students share 4 bagels equally.

we have been asked to find that

How many pieces does each person get?

Here we will have to use the concept of division. Because we are dividing bagels among the students.

So To get the number of pieces each will get divide 6 by 4.

Step-by-step explanation:

The half-life of radium-226 is 1620 yr. Given a sample of 1 g of radium-226, the quantity left Q(t) (in g) after t years is given by:Q(t)= 1/2^t/1620

Required:
a. Convert this to an exponential function using base e.
b. Verify that the original function and the result from part (a) yield the same result for Q(0), Q(1620), and Q(3240).

### Answers

Answer:

(a)

Step-by-step explanation:

We are given that

Half life of radium-226=1620 yr

The quantity left Q(t) after t years is given by

a. We have to convert the given function into an exponential function using base e.

=

=

=

(b)

=1

From original function

Q(0)=1

From exponential function

Q(3240)=0.249=

Hence, verified.
