Answer:
y = 5
Step-by-step explanation:
The 3 interior angles of a triangle sum to 180°
Sum the 3 given angles and equate to 180
100 + 4y + 25 + 3y + 20 = 180 ← simplify left side
7y + 145 = 180 ( subtract 145 from both sides )
7y = 35 ( divide both sides by 7 )
y = 5
Answer: a) 9 cm
explanation: since the length of the rectangle is 4 cm greater than the width, you can just take 9 cm (the length) minus 4, which gets you 5 cm. if we use the area formula (length x width), then 9 x 5 = 45 square cm.
Answer:
Tan B= 16/30
Step-by-step explanation:
Remember SOH CAH TOA. Tan is involved with this problem so we would use the TOA. TOA stands for: T-Tan, O- Opposite, and A- Adjacent.
First you want to find what is the opposite side of angle B (in meaning the side if you go straight out from the angle) which would be 16. You then need to find the adjacent side which is the side in between the given angle and 90 degree angle so that would be 30. TOA states that Opposite is over Adjacent so it would be 16/30.
A) the slope of the equation is 5, the y intercept is 10.
b) the rate of change is just the slope, so 5 but it means that they are picking 5 berries over that period of time. the initial amount is just the y intercept which is 10. this is just how many berries you start with.
c)
