Answer:
165 cm.
Step-by-step explanation:
Let h be the height of Cody on the first day of school last year.
We have been given that Cody was 165 cm tall on the first day of school this year, which was 10% taller than he was on the first day of school last year.
To find the height of Cody on the first day of school last year, we need to find h such that h plus 10% of h equals 165. We can represent this information in an equation as:
Let us divide both sides of our equation by 1.10.
Therefore, Cody was 150 cm tall on the first day of school last year.
Answer:
x ≈ 32.3
Step-by-step explanation:
Using the sine ratio in the right triangle
sin48° = 
= 
( multiply both sides by x )
x × sin48° = 24 ( divide both sides by sin48° )
x = 
≈ 32.3 ( to 1 dec. place )
Answer:
50 °= 283.15 K
Step-by-step explanation:
Answer:
Step-by-step explanation:
=> 3(5k + 2) + 5 = 3k - 1
=> 15k + 6 + 5 = 3k - 1
=> 15k + 11 - 3k + 1
=> 12k + 12
<u>Hence, correct answer is 12k + 12.</u>
Answer:
y = - 3x + 10
Step-by-step explanation:
We have to write an equation of a straight line in slope-intercept form that passes through the points (3,1) and (0,10).
Now, the equation of the straight line (using two points form) will be
⇒ y - 1 = - 3(x - 3)
⇒ y - 1 = 9 - 3x
⇒ y = - 3x + 10 (Answer)
{Since the slope-intercept form of a straight line equation is y = mx + c}
We know the equation of a straight line when any two points on the straight line (
), (
) are known, will be
