Answer:
E
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
Consider the triangle on the left
3rd angle = 180° - 60° - 90° = 180° - 150° = 30°
the 3rd angle of the triangle on the left = 30° ( vertically opposite angle ), so
∠ 1 = 180° - 30° - 65° = 180° - 95° = 85°
Answer:
20 m
Step-by-step explanation:
The maximum height is given by the vertex form of the equation, that is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given
h(t) = - 5t² + 20t ← factor out - 5 from each term
= - 5(t² - 4t)
Using the method of completing the square
add/subtract ( half the coefficient of the t- term)² to t² - 4t
h(t) = - 5(t² + 2(- 2)t + 4 - 4 )
= - 5(t - 2)² + 20 ← in vertex form
with vertex = (2, 20 )
The maximum height is at the value of k = 20
That is the maximum height is 20 m

She decided to test this by 200 adults, so. Divide 6 by 500 = 0.012 (200)=2.4mins.
<u>Answer:</u>
Lindsay used 16/24 yards of fabric and has 5/24 yards left over
<u>Step-by-step explanation:</u>
7/8 - 2/3 = ?
Since both fractions have unlike denominators, we are gonna have to rewrite the fractions so we can subtract. We are gonna find the least common denominators, to be able to subtract.
(7/8 x 3/3) - (2/3 x 8/8) = ?
Complete the multiplication and the equation becomes
:
21/24 (7/8) - 16/24 (2/3) = 5/24
