A right triangle has leg lengths of 3.4 cm and 6.7 cm. Which answer below shows the length of the triangle’s hypotenuse rounded to the nearest tenth?
A. 8.5 cm
B. 7.5 cm
C. 5.5 cm
D. none of the above

Answers

Answer:

D

Step-by-step explanation:

The hypotenuse squared is equal to the sum of the legs squared in a right triangle.

∴ c² = a² + b² (Pythagorean’s Theorem)

c² = 3.4² + 6.7² (substitute the given values for a & b)

c² = 11.56 + 44.89 (square both right hand terms)

c² = 56.45 (add the right hand side values)

c = √56.45 (square root of both sides)

c ≈ 7.5 to the nearest tenth QED

3 equivalent fractions for 2/3 are:

•4/6 (multiply the numerator and denominator by 2)
•6/9 (multiply the numerator and denominator by 3)
•8/12 (multiply the numerator and denominator by 4)

Basically all you have to do is multiply the numerator and denominator by any number as long as you keep it the same.

Hope you have a wonderful day ;)

Answer:

What slope is perpendicular to:
m = 5/8

Answers

the perpendicular slope would be m=-8/5

The slope that is perpendicular to m = 5/8 is given by; m' = -8/5

When dealing with slope - intercept form of equation of a line, the general equation is;

         y = mx + c

where;

m is the slope

c is the y-intercept

Now, for a line to be perpendicular to a line above that has it's slope as m, the slope of this new line will be the negative inverse of the first slope. This is;  m' = -1/m

Applying that to our question, it means the slope that is perpendicular to m = 5/8 is; m' = -1/(5/8) = -8/5

Step-by-step explanation:

Answer:

Step-by-step explanation:

If you are converting 40cm to one inch and the conversion ratio is 2.54 : 1, you would place 40 in the numerator as the original ration has 2.54/1 as a fraction and the same will apply to 40cm.

** This applies if you are finding which number is in the numerator and not the answer to how much 40cm in inches is.
