4y+10=30
4y=20
y=5
Since this is an isosceles, you know that angle B is congruent to angle C (they’re both 75°).
Answer:
Cynthia = 12 guavas
Bessy = 36 guavas
Aicel = 72 guavas
Step-by-step explanation:
Total guavas = 120
Let
Cynthia = x
Bessy = 3x
Aicel = 2(3x)
= 6x
x + 3x + 6x = 120
10x = 120
x = 120/10
x = 12
Cynthia = x
= 12 guavas
Bessy = 3x
= 3(12)
= 36 guavas
Aicel = 6x
= 6 × 12
= 72 guavas
Total = 74 + 36 + 12
= 120 guavas
a)
the average speed, well it does 10 ft in 1.6 secs, so is simply their quotient, 10/1.6 = 6.25 ft/s on average.
b)
over the horizontal, well, it covered horizontally 9.25 ft in those 1.6 secs, so their quotient is 9.25/1.6 = 5.78125 ft/s on average.
c)
we don't know the vertical distance, but

so, it covered vertically about 3.8 ft in those 1.6 secs, so then 3.8/1.6 = 2.375 ft/s on average
Answer:
cm²
Step-by-step explanation:
Surface area of the composite figure = Surface area of the lateral surfaces of the given pyramids
Lateral surface area of a square pyramid = 4
Therefore, lateral surface area of the pyramid
= ![4[\frac{1}{2}(24)(5)]](https://tex.z-dn.net/?f=4%5B%5Cfrac%7B1%7D%7B2%7D%2824%29%285%29%5D)
Now lateral surface area of the composite figure = 2(lateral surface area of two pyramids)
= ![8[\frac{1}{2}(24)(5)]](https://tex.z-dn.net/?f=8%5B%5Cfrac%7B1%7D%7B2%7D%2824%29%285%29%5D)
Therefore, Expression for the surface area of the given composite figure is,
cm²
