Answer: The ball will hit the ground in 2 seconds
Step-by-step explanation:
The formula for throwing a baseball in the air is represented by :
h = -16t² + 12t + 40
where h is the height of the ball and t is the time in seconds
Now we need to find after how many seconds will the ball hit the ground
When the ball hits the ground the height of the ball is 0
⇒ -16t² + 12t + 40 = 0
⇒ 4t - 3t - 10 = 0
⇒ 4t² - 8t + 5t - 10 = 0
⇒ 4t(t - 2) + 5(t - 2) = 0
⇒ t cannot be negative so t = 2
Hence, The ball will hit the ground in 2 seconds

In square units, what is the area of the blue sector in the figure above? Round to the nearest tenth.
Given:
A figure of a circle with radius 8. The central angle of the blue sector is 60 degrees.
To find:
The area of the blue sector.
Solution:
Area of a sector is:
[tex]A=\pi r^2\dfrac{\theta}{360^\circ}[/tex]
Where, r is the radius and [tex]\theta [/tex] is the central angle of the sector in degrees.
Putting [tex]r=8, \theta=60^\circ, \pi=3.14[/tex], we get
[tex]A=(3.14)\cdot (8)^2\cdot \dfrac{60^\circ}{360^\circ}[/tex]
[tex]A=(3.14) \cdot (64)\cdot \dfrac{1}{6}[/tex]
[tex]A=33.49333....[/tex]
Approximate the value to the nearest tenth.
[tex]A\approx 33.5[/tex]
Therefore, the area of the blue sector is about 33.5 sq. units.
Find the volume of the cone use pi=3.14 Round to the nearest hundredth?
Answer:
Volume=2616.67
Step-by-step explanation:
V=1/3pi r squared height
V=1/3(3.14)(10)squ.(25)
V=1/3(3.14)(100)(25)
V=2616.66667
V=2616.67
Eric's team won 20 games last season and James team won 6 games. Which equation will find how many more games Eric's team won than James team?
A.) y + 6=20
B.) 6y=20
C.) y-6=20
D.) Y/6=20
Answer:
A) y + 6 = 20Step-by-step explanation:
Let the difference is y.
Then it is:
y = 20 - 6Equivalent equation is:
y + 6 = 20Correct choice is A
Estimate the solution of the system x+y=4 2x-y=6 by sketching a graph of each linear function. Then solve the system algebraically. Use your estimate to judge the reasonableness of your solution. The estimated solution is The algebraic solution is The solution is/is not reasonable because
Answer:
(10/3, 2/3)
Step-by-step explanation:
You may find it easier to write these two equations x+y=4 2x-y=6 in a column:
x+y=4
2x-y=6
Adding these together will eliminate y:
3x = 10. Then x = 10/3.
Substituting 10/3 for x in the first equation results in:
10/3 + y = 4
Clear fractions by multiplying all three terms by 3:
10 + 3y = 12
Then 3y = 2, and y = 2/3.
The solution is (10/3, 2/3)
what is the area of a quadrilateral with vertices at (-6,6), (-1,6),(-6,10), and (-1,10)
Answer: 20
Step-by-step explanation:
The area of a quadrilateral with given vertices is 20 square units.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
We have to determine the area of a quadrilateral with vertices at (-6,6), (-1,6),(-6,10), and (-1,10).
As per the attached graph, we can see that the dimensions of the rectangle are as follows:
Length (L) = 5 units
Width (W) = 4 units
Area of the rectangle = L × W
Area of the rectangle = 5 × 4 = 20 square units

A triangle has one angle of 120 degrees what must be true about the other two angles A- the sum of the two angles must be equal to 120 degrees. B- the two angles must be the same measure C- the sum of two angles must be 60 degrees
Answer:
C
Step-by-step explanation:
Since all triangles' angles have a sum of 180 degrees, it can't be A, because that would make it 240 degrees. That leaves us with B and C. While B could be true, we don't know it for sure. Therefore, C is the correct answer because adding them should equal 60 degrees, which, adding them to the first angle (which was 120 degrees), would 180 degrees.

Which figure is a translation of figure 1?
Answer:
triangle 4.
Step-by-step explanation:
A translation only moves vertically or (and) horizontally our image.
This means that a translation does not change the size
A translation does not rotate the image.
Then a translation of triangle 1 needs to have the same size than triangle 1, and the same "direction" (in triangle 1 we can see that the hypotenuse is at the right side, then in the translated triangle we also should have the hypotenuse at the right side).
Then the only option that seems correct is triangle 4
