Robert jumps : 6 1/12 and 5 2/3

Answer:

Answer:

No Robert is not correct because his better long jump was 1.33 foot farther than May's better long jump.

Step-by-step explanation:

Mays jumps

(i)

=>

=>

=>4.667

(ii)

=>

=>

=>4.75

May's better long jump is

Robert jumps :

(i)

=>

=>

=>6.08

(ii)

=>

=>

=> 5.66

Robert's better long jump is

Now the difference between Robert's better long jump and May's better long jump is

=>

=>

=>

=>6.08 - 4.75

=> 1.33

The measure of one of the acute angles in a right triangle is five times the measure of the other acute angle. what is the measure of the smaller acute angle?

he measure of the smaller acute angle in a right triangle is 15 degrees.

- Let the bigger angle be a.

- Let the smaller angle be b.

To find the measure of the smaller acute angle:

Translating the word problem into an algebraic expression, we have;

In Trigonometry, a right triangle is a triangle that has the sum of its interior angles equal to ninety (90) degrees.

Mathematically, this is given by the formula:

Smaller angle, b = 15 degrees.

I really need help please. Find the distance between the two points in simplest radical form. (−9,−4) and (0,−7)?

Answer:

= 3sqrt(10)

Step-by-step explanation:

The distance between two points is found by

d =sqrt( x2-x1)^2 + (y2-y1)^2)

= sqrt( 0--9)^2 +(-7--4)^2)

= sqrt( (9)^2 + (-7+4)^2)

= sqrt(9^2 + (-3)^2)

= sqrt(81+9)

= sqrt(90)

We know that sqrt(ab) = sqrt(a) sqrt(b)

= sqrt(9) sqrt(10)

= 3sqrt(10)
