Answer:

b) EF = GF , as both of them are at equal distance from the center

Step-by-step explanation:

Here we are given a ΔEFG inscribed in a circle. We have to determine whether EF = Gf and why ?

Here we see that the center is A

And EF and GF forms the chords of this circle.

The distance of these chords from the center is given as AD and DH . It is also given that both are equal.

The property of a circle says that

When chords are drawn at equal distance from the center , the chords are equal to each other. Hence we have EF and GF equal to each other.

Answer:

B. /EF/ /GF/ because both segments are the same distance from the centre of he circle A

Step-by-step explanation:

Considering the given diagram, both /EF/ and /GF/ are chords. And the two chords are at the same distance to the centre of the circle. Thus /EF/ = /GF/, the two chords are equal in length.

Even, redrawing the chords in different segments of the circle and at same distance to the centre does not make them to be unequal.

A store sells cans of paint for $8 each, and brushes for $12 each. If they sell 100 items, and

Montano1993 [528]

Answer:

B.) 80 cans, 20 brushes

Step-by-step explanation:

Let the cans of paint be represented by variable p , and brushes by variable b

The first equation would be ; p + b = 100

p = 100 - b

The second equation would be;

8p + 12b = 880

Replace p in the equation by (100-b);

=8(100-b) + 12b =880

=800 - 8b +12b = 880

= subtract 800 from both sides to get;

4b = 880-800

4b = 80

divide both sides by 4 to solve for b;

b= 80/4

b = 20

If p + b = 100, then p+20 = 100

p = 100-20

p = 80

Therefore, they sold 80 cans of paint and 20 brushes

Each of the 6 cats in a pet store was weighed. Here are their weights

zhannawk [14.2K]

Answer:

Mean= 10.83

Median= 9.5

Step-by-step explanation:

Given number,

10, 15, 8, 11, 9, 12

N= 6

As we know,

Mean= Ex/N

=10+15+8+11+9+12/6

=65/6

=10.83

Therefore, Mean= 10.83

Now,

Median(MD)= (N+1/2)th item

= 6+1/2

=7/2

=3.5th item

So, Median(MD)= 3th+4th/2 item

= 8+11/2

= 19/2

= 9.5

Therefore, Median= 9.5

Find two consecutive even integers such that the square of the first, decreased by the second is 130

marta [7]

Let's make the first even integer m and the second even integer n. The square of the first, decreased by the second is 130 is:

$m^{2}$ -n=130 ---> Add n to each side
$m^{2}$ =130+n ---> Take the square root of each side
m=± $\sqrt{130+n}$

Let's look at the first square number above 130, which is $12^{2}$ . m is 12, therefore the next consecutive even integer is 14.

$12^{2}$ =144
144-14=130

The two consecutive integers are 12 and 14
