A triangle can be made by segments that are 15.9 cm, 10 cm and 25.9 cm.
Answer:
false
Step-by-step explanation:
for the segments to form a triangle, then
the sum of any 2 must be greater than the third.
15.9 + 10 = 25.9 ← not greater than 25.9
10 + 25.9 = 35.9 > 15.9
15.9 + 25.9 = 41.8 > 10
then the 3 segments will not form a triangle.

Sports A baseball is thrown into the air with an upward velocity of 30 ft/s. Its
height h, in feet, after t seconds is given by the function.h= -16t2 + 30t + 6. How
long will it take the ball to reach its maximum height? What is the ball's maximum
height? What is the range of the function?
Step-by-step explanation:
so, the function is
h(t) = -16t² + 30t + 6
we get the point of the extreme value(s) by finding the zero solution(s) of the first derivative of the function.
h'(t) = -32t + 30
finding the zero solution
-32t + 30 = 0
30 = 32t
t = 30/32 = 15/16 seconds
after 15/16 seconds (not even a full second) the ball reaches its maximum height.
the height at that maximum is then h(15/16) :
-16(15/16)² + 30×15/16 + 6 = - 15²/16 + 450/16 + 6 =
= -225/16 + 450/16 + 96/16 = 225/16 + 96/16 = 321/16 =
= 20.0625 ft
and so, the range (the interval or set of all valid functional values) is
0 <= h(t) <= 20.0625
as naturally, on a normal surface and environment, the height of the ball cannot go below 0 (when it hits the ground, it's over).

A red ball and 4 white balls are in a box. If two balls are drawn without
replacement, what is the probability of
a getting two white balls?
Answer:40%
Step-by-step explanation:
10 divided by 2 is 5.
Since there are five balls, and four are white and one is red, if you double that amount, then you would have 8 white and 2 red. So four white balls is equal to 40%.

The radius of a sphere is 3 cm. What is the sphere's volume? Round to the nearest tenth.
Answer:
113.1
I answered this question before with the exact radius, and I remember the answer being this.
Formula:
V=4
3πr3=4
3·π·33≈113.09
Hope this helps!
Answer:
Step-by-step explanation:
the answer is 113.1 cm³
The volume of a sphere of radius r is V = (4/3)πr³.
If the radius is 3 cm and the answer is to be expressed to the nearest tenth, then we get:
V = (4/3)(3.14159)(3 cm)³
= (4/3)(84.82 cm³
= 113.1 cm³

A merchant offers a large group of items at 32% off later the merchant takes 16% off the sale prices and claims that the final price of these items is 186 off the original price.
what is the total percent discount?
The total discount was 48% of the original price of $387.50
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the original price.
Discount = (32% of x) + (16% of x) = 0.48x = 48% of x
The final price of these items is 186 off the original price.
x - 0.48x = x - 186
x = $387.50
The total discount was 48% of the original price of $387.50
