Answer:
The maximum height of the ball was 30 feet
The ball was in the air for 6 seconds
Step-by-step explanation:
The maximum height was 30 feet because that is the highest y-value before the y-values start decreasing. You could also call it the peak.
You would know the ball was in the air for 6 seconds because the time elapsed between it's liftoff at 0 feet and it's landing at the other 0 feet was 6 seconds.

Each school bus going on the Field Trip holds 36 students and 4 adults.There are 6 filled buses in the Field Trip.How many People are going on the Field Trip? Answer Now Please it is homework!
Answer:
240 peopleStep-by-step explanation:
Step one:
given data
Number of Students in a bus= 36
Number of Adults in a bus= 4
Total number of persons in a bus= 36+4= 40 persons
Step two:
in one bus there are 40 people
in 6 filled buses there are 6*40
=240 peoples.
Therefore there are 240 people going on the field trip
Suppose there is a 1.1 drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 60.5, what will be the temperature when the plane reaches an altitude of 11,000?
Answer:
48.4° CStep-by-step explanation:
Step one:
We are told that there is 1.1° drop in temperature for each 1000 ft climb.
since the given altitude is 11,000ft,
hence there =(11000/1000)*1.1
= 11*1.1
=12.1°C drops in temperature.
Therefore, given that the temperature on the ground is 60.5° C
The temperature above is 60.5-12.1=48.4° C
The plane reaches an altitude of 11,000 is 48.4° C
During a typing test , bob typed 40 words in 2/3 of a minute what is bobs typing speed.
Work Shown:
40 words = (2/3) of a minute
3*40 words = 3*(2/3) of a minute ... multiply both sides by 3
120 words = 2 minutes
120/2 words = 2/2 minutes .... divide both sides by 2
60 words = 1 minute
Bob's speed is 60 words per minute (wpm)

Answer:
Step-by-step explanation:
The triangle should equal 180 degrees. You already have 84+60= 144
Take that 144 with the equation of the other angle. 144-180 is 36
5x+1=36 subtract 1 from both sides
5x=35 divide by 5
x=7
check:
36 + 84+60= 180

What value could be put in the blank to make this equation have no solution?
2(5x+3) = 3x - 9 + ____
Answer:
3/7
Step-by-step explanation:
Let's solve your equation step-by-step.
2(5x+3)=3x+9
Step 1: Simplify both sides of the equation.
2(5x+3)=3x+9
(2)(5x)+(2)(3)=3x+9(Distribute)
10x+6=3x+9
Step 2: Subtract 3x from both sides.
10x+6−3x=3x+9−3x
7x+6=9
Step 3: Subtract 6 from both sides.
7x+6−6=9−6
7x=3
Step 4: Divide both sides by 7.

What is the final amount if 1885 is increased by 5% followed by a further 18% increase
9514 1404 393
Answer:
2335.515
Step-by-step explanation:
The first increase multiplies the original amount by 1 + 5% = 1.05.
The second increase multiplies the already increased amount by 1 + 18% = 1.18.
Then the final amount is ...
1885(1.05)(1.18) = 2335.515

What is expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.
Given, We can describe 15x-10 as an expression, We would describe 9x+5=32 as an:
A function is a collection of ordered pairs where each input (x-value) has a single relationship to each output (y-value). An equation need not always be a function. If an equation satisfies the criteria for a function, then it is a function. However, not all equations are functions.
A number, a variable, or a mix of numbers, variables, and operation symbols make up an expression. Two expressions joined by an equal sign form an equation.
Therefore, We would describe 9x+5=32 as an equation or a function.

2
3
4
6
please answer
Answer:
a = 6
Step-by-step explanation:
Given that (x - 2) is a factor of P(x) , then P(2) = 0 , that is
P(2) = 2² - 5(2) + a = 0 , so
4 - 10 + a = 0
- 6 + a = 0 ( add 6 to both sides )
a = 6

Rotation 90° counterclockwise gives (x, -y) → (-y, -x)
16) b) (0, 0),
Reflection about the line y = x gives (x, y) → (y, x)
Reflection about the line y = -x gives (x, y) → (-y, -x)

The preimage and the image formed by a rigid transformation are always congruent
What is the volume of a hemisphere with a radius of 9.7 cm, rounded to the nearest tenth of a cubic centimeter? please i need help ill do a zoom call and i'll give you all my Branly points if uu help me.
Answer:
volume of hemisphere =1912.26cm^3
Step-by-step explanation:
radius(r)=9.7cm
now volume of hemisphere=(2/3)π[tex]r^{3}[/tex]
=(2/3)*(22/7)*(9.7)^3
=(2/3)*(22/7)*912.673
=(2/3)*2868.40086
=1912.26cm^3
The volume of a hemisphere is [tex]1910.52 cm^{3}[/tex].
What is volume of a hemisphere?
A hemisphere is half of a full sphere, we can calculate the volume of a hemisphere just by halving the volume of the complete sphere.
So, we can calculate the volume of a hemisphere by using the following formula,
[tex]$V=\frac{2}{3}\pi {{r}^{3}}$[/tex]
Here, [tex]r[/tex] is the radius, [tex]V[/tex] is the volume of hemisphere.
So,
It is given that the radius is [tex]9.7 cm[/tex].
We have to find [tex]V[/tex].
So,
[tex]$V=\frac{2}{3}\cdot 3.14\cdot {{\left( 9.7 \right)}^{3}}$[/tex]
[tex]V=1910.52[/tex]
Hence, the volume of hemisphere is [tex]$1910.52\text{ c}{{\text{m}}^{3}}$[/tex].
