Answer:

x = 71°

Step-by-step explanation:

Segments of tangents from the same external point are congruent, that is

AT = BT

Then Δ ABT is isosceles with base angles congruent , so

x = $\frac{180-38}{2}$ = $\frac{142}{2}$ = 71°

Write down the nth term of this sequence 2,7,12,17,22

ki77a [65]

There is a pattern. Each number is added by 5. So take 22 and add 5 to get 27. Just repeat until you find your answer, which would be 42.

Help me plz it's the first time using it

rjkz [21]

This whole problem rests on one thing:
Do you know the formula for the volume of this kind of shape ?
If you do, then the problem is easy. If you don't, then it's impossible.

This is the shape of a book, an ice cube, a brick, or a slab.

The volume is always

(length) x (width) x (height) (in any order) .

They all have to be in the same unit, and then the volume
is in the cubic-(...) of that unit.

In this picture, there's a tiny hiccup with the units ... the length and
the width are in meters, but the height is in centimeters, so you need
to change that one to meters before you can multiply them.

Notice right above the picture, it reminds you that

   (1 meter = 100 centimeters) .

So the height of the slab (10 cm) is the same as 0.1 meter.

Now you have all 3 of the dimensions in meters, so you're
ready to multiply them and get the volume.

   Volume = (length) x (width) x (height)

   = ( 8 m ) x ( 6 m ) x ( 0.1 m )

   =    4.8 cubic meters .

Question:
Does Meg have enough concrete to make the slab
with the dimensions shown ?

Answer: Yes .

Explanation:
Meg mixed 5 cubic meters of concrete.
She needs 4.8 cubic meters to pour the floor with those dimensions.
She has enough concrete to do the job.
All she needs is the whole football team to come over and help her
   pour, smooth, and finish it. Concrete is hard hard work !

What is the solution for this system of equations y = x - 4 Y = -x + 6

lana66690 [7]

Our system of equations is:

y = x - 4

y = -x + 6

We can solve this system of equations by substitution. We already have one equation solved for the variable y in terms of x, so we can substitute in this equivalent value for y into the second equation as follows:

y = -x + 6

x - 4 = -x + 6

To simplify this equation, we first are going to add x to both sides of the equation.

2x - 4 = 6

Next, we are going to add 4 to both sides of the equation to separate the variable and constant terms.

2x = 10

Finally, we must divide both sides by 2, to get the variable x completely alone.

x = 5

To solve for the variable y, we can plug in our solved value for x into one of the original equations and simplify.

y = x - 4

y = 5 - 4

y = 1

Therefore, your final answer is x = 5 and y = 1, or as an ordered pair (5,1).

Hope this helps!

A dice is rolled twice. What is the probability of rolling a 3 followed by a 2?

aliina [53]

The two rolls of the number cube are independent events because

the result of 1 roll does not affect the result of the other roll.

To find the probability of two independent events, we first find

the probability of each event, then we multiply the probabilities.

We can find the probability of an event using the following ratio:

<em>number of favorable outcomes/total number of outcomes</em>

Since there is only one way to roll a 3 and there are six

possible outcomes, 1, 2, 3, 4, 5, and 6, the probability of rolling a 3 is 1/6.

Since there is also only one way to roll a 2 and there are

six possible outcomes, the probability of rolling a 2 would be 1/6.

Now we multiply the probabilities.

1/6 x 1/6 is 1/36.

So the probability of rolling a 3 and a 2 is 1/36.
