Alexus [3.1K]

Answer:

He can cut 70 pieces of ribbon.

Step-by-step explanation:

Hi, 1 decameter is equal to 10 meters. So each piece of ribbon is 10 meters long. Since he has 7, we have to multiply the length in meters of each ribbon (10) by the quantity (7).

10x 7 = 70 meters

He needs to cut pieces of ribbon that are each 1 meter long, so we have to divide the total meters of ribbon that Glenn has(70), by the length of each ribbon asked(1).

70/1= 70

He can cut 70 pieces of ribbon.

If the given values in a right triangle are cos A =
Vlad1618 [11]
See the picture attached to better understand the problem

we know that
in the right triangle ABC
cos A=AC/AB
cos A=1/3
so
1/3=AC/AB----->AB=3*AC-----> square----> AB²=9*AC²---->  equation 1

applying the Pythagoras Theorem
BC²+AC²=AB²-----> 2²+AC²=AB²---> 4+AC²=AB²----> equation 2

substitute equation 1 in equation 2
4+AC²=9*AC²----> 8*AC²=4----> AC²=1/2----> AC=√2/2
so
AB²=9*AC²----> AB²=9*(√2/2)²----> AB=(3√2)/2

the answer is
the hypotenuse is (3√2)/2
