Answer:

7. Inscribed angle

Step-by-step explanation:

7. Inscribed angle

8.

y° = 70°

z° = 140°

8. y° and 70° are the measures of the angles subtended in the same arc. So, they would be equal.

Therefore, y° = 70°

Measure of central angle is two times the measure of the inscribed angle.

Therefore,

z° = 2* 70° = 140°

katrin [286]
The answer would be approximately 56.52 inches squared.

You are suppose to find the lateral surface area, since the label only go around the can, excluding the top and bottom.
To find the lateral surface area, you'd need to find the circumference of the circle, and then multiply that by the height.
Since C = πd, 3.14..*3 ≈ 9.42. And 9.42*6 = 56.52. Conclusively, the approximate amount of paper needed to make the can's label would be about 56.52 inches squared.

HELP FASSTT THANK U IF SO
valentina_108 [34]

Answer:

The answer is -13/8 or -1 5/8 in mixed form.

Step-by-step explanation:

The fraction 1 5/8 converted to improper is 13/8 so count 13 points to the right of the number line from 0. So that is where it falls.

Now if we are to find the opposite of a positive integer or fraction we are just to put a negative mark so it will be -1 5/8 or -13/8 in improper form. So just count 13 points to the left of the number line from 0 and that's your answer buddy!

But tbh this is actually an extensive and time taking process but if you follow this you can be sure of your answer. So the easier process is to see the whole and the parts of whole. As you can see there are 8 parts between each number so it means each number is divided into 8 parts and to make it easier the fraction shows that 1 5/8 has 8 parts for each to. So we will take the 1 of the 1 5/8 and skip 8 parts to the whole number 1. Then we will take the 5 from 5/8 and count 5 points from 1. That's the position of 1 5/8 on the number line. As for the opposite, add negativity sign and do just the same! And that's the answer!

HOPE it helps though...

A gardener brought 5 rabbits, after 2 months rabbits became 10, and after 4 months they became 20. If the growth continues on th
Natali [406]

Answer:

<em>The amount of rabbit after 1 year will be </em><em>320</em><em>.</em>

Step-by-step explanation:

A gardener brought 5 rabbits, after 2 months rabbits became 10.

The growth continues on the same ratio.

This represents a geometric sequence with 1st term as 5 and common ratio as 2.

As we have to find the amount of rabbit after 1 year, so the we have to find \dfrac{12}{2}+1=6+1=7th term. As the time difference between each counting is 2 months, so we divided 1 year or 12 months of time by 2.

nth term in a G.P is,

T_n = ar^{n-1}

Putting the values,

T_7 = 5\times (2)^{7-1}=5\times 2^6=320
