Answer:
see the explanation
Step-by-step explanation:
we know that
A gross is equal to 120 ones or ten dozen
what is 15 tens - 1 gross
we know that
15 tens means ----> That you are adding 10, 15 times or multiplying 10 by 15, which gives you

1 gross means ---> That you are adding 10, 12 times or multiplying 10 by 12
which gives you

so
The algebraic expression of 15 tens - 1 gross is equal to

Convert to word expression
3 tens
C, not sure but C. It makes sense to me & I got it right when I did it
Answer:
133.96 meters squared
Step-by-step explanation:
To calculate the area of a circle, simply multiply the radius squared, by pi.
A = pi x r^2
A = pi x 6.53^2
A = pi x 42.6409
A = 133.9603382
The area of the circle is approximately 133.96 meters squared.
Hope this helps! :)
Answer:
The value of x = 13cm and y = 12cm.
Step-by-step explanation:
P is the exterior point to the circle with centre O
Radius = 5cm
Length of the tangent = 12 cm
Distance between the point and centre of the circle = x cm
We know that
The angle between the radius of the circle and the tangent at the point of contact is 90°
By Pythagoras Theorem
Hypotenuse² = Side²+Side²
⇛x² = 12²+5²
⇛x² = 144+25
⇛x² = 169
⇛x² = 13²
<h3>⇛x = 13 cm</h3>
We know that
The lengths of tangents drawn from the exterior point to the circle are equal.
<h3>y = 12 cm</h3>
<u>Answer</u><u>:</u> The value of x=13cm and y = 12cm.
