Answer:
4 seconds
Step-by-step explanation:
Given
[tex]h(t) = -25t + 100[/tex]
Required
Determine what time it hits the ground
When the ball is on the ground, the height is at 0
i.e.
[tex]h(t) = 0[/tex]
Substitute 0 for h(t) in [tex]h(t) = -25t + 100[/tex]
[tex]0 = -25t + 100[/tex]
Collect Like Terms
[tex]25t = 100[/tex]
Solve for t
[tex]t = 100/25[/tex]
[tex]t = 4[/tex]
Hence, the ball will hit the ground in 4 seconds

What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that each of the options below describes a relationship that you need to graph in a coordinate plane.
The relationship showing the slope of 50 is:-
Driving 450 miles in 9 hours,
Slope = 450 / 9 = 50

Answer:
1. 20
2. Segment SW equals 8
Step-by-step explanation:
Setup the equation 6x+5=8x and then solve for x. x comes out to be 5/2. The substitute that in for x and solve. 6(5/2)+5 and this equals 20, your solution.
Segment SW=8 because of the perpendicular bisector theorem. It states that if a point lies on the perpendicular bisector of a segment, then it is equidistant from the endpoints of that segment (i.e., equal length). This makes Segment SW=8

th
A) 12
B) 16

Step-by-step explanation:
Possible amount of hours to install 100 windows = 16 hrs.
The correct option is (B).
What is an Inequality?In Algebra, inequality is a Mathematical statement that shows the relation between two expressions using the inequality symbol. The expressions on both sides of an inequality sign are not equal. It means that the expression on the left-hand side should be greater than or less than the expression on the right-hand side or vice versa. If the relationship between two algebraic expressions is defined using the inequality symbols, then it is called literal inequalities.
Given,
Number of windows Jason can install in 1 hour = 6 ≤ x ≥ 8
Time taken in installing 1 window = 1/6 ≤ 1/x ≥ 1/8
Time taken in installing 100 windows = 1/6 × 100 ≤ 1/x × 100 ≥ 1/8 × 100
Time taken in installing 100 windows = 12.5 ≤ t ≥ 16.67
Then the possible amount of time taken will be in range of 12.5 to 16.67 hrs.
Hence, Jason will take around 16 hrs. to install 100 windows.

solve for x:
-6 + 4x = 13
Answer:
x = 19/4
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
-6 + 4x = 13
Step 2: Solve for x
Add 6 to both sides: 4x = 19Divide both sides by 4: x = 19/4Step 3: Check
Plug in x to verify it's a solution.
Substitute: -6 + 4(19/4) = 13Multiply: -6 + 19 = 13Add: 13 = 13Here, we see that 13 does indeed equal 13.
∴ x = 19/4 is a solution of the equation.
Write the equation of the line that passes through the points (4, -6) and (-2,3).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal

Answer:
x = 10
Step-by-step explanation:
An isosceles triangle has two sides of equal length. In this triangle, there is a little line in the middle of two out of the three sides of the triangle. This line tells us that those two sides are equal. We know that the value of these sides are 4x - 8 and 2x + 12. So, to find the value of x, we can set the equations equal to each other and solve for x:
4x - 8 = 2x + 12
Subtract 2x from both sides to isolate x:
2x - 8 = 12
Add 8 to both sides:
2x = 20
Divide both sides of the equation by 2 to find the value of x:
x = 10

Find x and y intercepts!! show work plzzz
Answer:
(-15, 0) --> x intercept
(0, 15) --> y intercept
Step-by-step explanation:
First, you need to find the equation of the line:
gradient equals 1 --> (6 - 11)/(-9 - (-4))
y = x + c
sub point (-9, 6)
6 = -9 + c
c = 6 + 9
c = 15
Equation of line: y = x + 15
x-intercept is when y = 0
0 = x + 15
x = -15 (that's the x-intercept)
(-15, 0)
y-intercept is when x = 0
y = 0 + 15
y = 15 (this is the y-intercept). The y-intercept is also the contant 'c'
(0, 15)
A rectangle has a perimeter of 42 m and a length of 15 m. What is
the width of this rectangle in metres? (Perimeter = 2(length + width))
Answer:
6 meters
Step-by-step explanation:
the perimeter is all of the sides added up so to find the added width you subtract the added length which is 30 so 42-30 is 12 so the added width is 12. To find one width you divide 12 by 2 so one width of the rectangle would be 6 meters
0.00000012+8*10^-7 scientific notation
Answer:
9.2*10^-7
Step-by-step explanation:
Move decimal until there is one number to the left. The number of times moved will be the exponent. If the decimal moves left the exponent is positive, if it moves left it is negative.
So 0.00000012=1.2*10^-7
1.2*10^-7 + 8*10^-7
9.2*10^-7

Kailey correctly graphed the opposite of –3.3 on the number line.
A number line going from negative 5 to positive 5. Point A is between negative 4 and negative 3, point B is between negative 3 and negative 2, point C is at 3.3, and point D is at 3.9.
Which point could be the point Kailey graphed?
A
B
C
D
Answer:
C
Step-by-step explanation:
The opposite of negative 3.3 is positive 3.3 or just 3.3 so therefore the answer would be C as it is slightly ahead of 3 on the number line but not so far as to indicate anything larger.

Answer:
70°
Step-by-step explanation:
since two lengths are equal to 3.5 that’s means there’s are two equal angles (55° and 55°)
a triangle adds up to 180°
so to find x we set this up:
x +55 +55 = 180
x + 110 = 180
x = 70°
