In a 45-45-90 triangle, what is the length of the hypotenuse when the length of one of the legs is 11 in.?

Answers

Answer:

= 15.556 in

Step-by-step explanation:

Since this is a 45-45-90 triangle, we can tell that;

This is a right triangle
This is an isosceles triangle

One of the theorems of geometry, the Isosceles Right Triangle Theorem, says that the hypotenuse is √2 times the length of a leg.

Therefore;

hypotenuse = leg × √2

If we take hypotenuse as x

Since the leg is 11;

Then; x = 11√2

x = 11/√2

x = 15.556 in

Convert 4/15 to a percent

I need to solve: -3(8x); x = 1/4. Using substitution ro find the value of expression

Answers

First, find the value of the expression within the parentheses, which is 8x. Since x=1/4, 8x=8/4 or 2. Next, multiply this value by -3. -3*2=-6

Jack can swim 3 laps in 7 minutes.At this rate, how many laps can Jack swim in 28 minutes?

Answers

Jack can swim 12 laps in 28 minutes. 28 minutes is 4 times greater than the time it took him to swim 3 laps. With 28 minutes he should therefore be able to swim 4 times as many laps. 3 times 4 equals 12

he can swim 3 laps in 7 minutes.
28÷7=4
4*3=12
we can conclude that in 28 minutes he can swim 12 laps.
