Answer:
The mass of the larger hummingbird is 7 1/2 or 15/2.
Step-by-step explanation:
Bee hummingbird = 1 1/4g
Larger hummingbird = 6x that
So,
1 1/4 x 6 = 7.5
7.5 as fraction = 7 1/2 or 15/2
Whenever you reflect a point over the x axis, the x coordinate stays the same and the y coordinate is negated. In this case, the y coordinate which is 3 will be negated to become -3, and the x coordinate which is -5 will remain the same. Therefore, the new point is (-5,-3).
I hope this helps.
The height of purse which is in trapezoid shape is 26 cm
<em><u>Solution:</u></em>
Clara has a purse in the shape of a trapezoid
<em><u>The area of trapezoid is given by formula:</u></em>
Where,
"h" is the height
"a" and "b" are the parallel sides length
From given,
Area = 754 cm
a = 22 cm
b = 36 cm
h = ?
<em><u>Substituting the values in formula,</u></em>
Thus height of purse which is in trapezoid shape is 26 cm
The equivalent equation of the quadratic equation (x² – 1)² – 11(x² – 1) + 24 = 0 is u² - 11² + 24 = 0
<h3>How to determine the equivalent equation?</h3>
The equation is given as:
(x² – 1)² – 11(x² – 1) + 24 = 0
Let u = x² - 1
So, we have:
u² - 11² + 24 = 0
Hence, the equivalent equation of the quadratic equation (x² – 1)² – 11(x² – 1) + 24 = 0 is u² - 11² + 24 = 0

First, pass all the rate of inflation to ballons/hour
John: 1 b/15s * 3600 s/h = 240 b/h
Jamie: 1 b/20s * 3600 s/h = 180 b/h
Jake: 180 b/h
Then sum the rates to obtain the total rate
Total ballons per hour: 240 b/h + 180 b/h + 180b/h = 600 b/h
If it passes x hours the number of ballons inflated is 600*x
The number of ballon defective are 600*x/80
The number of ballons effectiveley inflated = 600x -600x/80 = 600x - 7.5x = 592.5x.
Answer: option A)
