Answer:

We have 7 complete teams

Step-by-step explanation:

Here, we have students preparing to make a team of 8 students per team. We now want to know how many complete teams they can make if they are a total of 60;

To get this, we need the multiples of 8;

we have;

8, 16 , 24 , 32, 40 , 48 , 56

So breaking it in 8s, we have;

8 8 8 8 8 8 8

We have 7 8s;

So there would be four left overs

Find the values of x and y. lines that appear to be tangent are tangent

Ket [755]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The value of $y = 122^o$

The value of $x = 61^o$

Step-by-step explanation:

Generally the total angle that make up a circle is

$\theta _T = 360$

From the diagram we see that

$\theta _T = y^o + 238^o$

=> $y^o = 360 -238$

$y^o = 122^o$

Generally angle that is formed as a result of interception of a chord and a tangent is equal to the intercepted arc divided by 2

This implies that

$x = \frac{y}{2}$

substituting values

$x = \frac{122}{2}$

$x = 61^o$

Triangle abc is equal to triangle pqr, angle p=8x+4, angle a=5x+16 , and angle q=10x+2. find angle r

saul85 [17]

Answer: b.not enough info

Step-by-step explanation:

Corresponding angles of congruent triangles are congruent, so $\angle A =\angle P$

However, we don't have all 3 interior angles of either triangle, so we cannot conclude anything.

The limit as x-approaches 3 of f(x) is x-3 over x squared -9

Luden [163]

notice that the denominator can be factored into (x-3)(x+3).

Now you can cross out (x - 3) from the numerator and denomiantor resulting in a simplified fraction of $\frac{1}{x+3}$

Plug the limit value (which is 3) into the simplified fraction.

Answer: $\frac{1}{6}$
