Y and x have a proportional relationship, and y = 25 when x = 60. What is the value of x when y = 30?

1 answer:

3 0

The equation governiong this relationship is y = kx. Since y = 25 when x = 60,
25 = 60k, and k=(5/12). Thus, the equation is y = (5/12)x.

If y = 30, then 30 = (5/12)x. Mult. both sides by 12/5 to obtain the value of x:

(12/5)(30) = 360/5 = 72

Answer:

BC = 10.24

Step-by-step explanation:

You can use the Pythagoras theorem for this question

$a^{2}$ + $b^{2}$ = $c^{2}$

a = 8cm

b = ???

c = 13cm

We will solve for B (length BC)

$a^{2}$ + $b^{2}$ = $c^{2}$

$8^{2}$ + $b^{2}$ = $13^{2}$

Rearrange for b

$b^{2}$ = $13^{2}$ - $8^{2}$

$b^{2}$ = 105

b = $\sqrt{105}$

b = 10.24

Ok so I got an 18/24 on a Comprehension check in English 1. Also there were 8 questions and each of them were worth 3 points. So

BaLLatris [955]

The point value is irrelevant. 18/24 as a decimal is 0.75, so your grade was 0.75, or 75%

Your grade is 75% in percentage form.
