Answer:
26.5 units
Step-by-step explanation:
The height of the ball at any time t is given by :
[tex]h(t)= -16t^2 + 40t + 1.5[/tex] ...(1)
We need to find the maximum height of the ball.
For maximum height, put [tex]\dfrac{dh}{dt}=0[/tex]
i.e.
[tex]\dfrac{d( -16t^2 + 40t + 1.5)}{dt}=0\\\\-32t+40=0\\\\t=\dfrac{40}{32}\\\\t=1.25\ s[/tex]
Put t = 1.25 in equation (1) to find the maximum height.
So,
[tex]h(t)= -16(1.25)^2 + 40(1.25) + 1.5\\\\=26.5\ units[/tex]
So, the maximum height reached by the ball is 26.5 units.

Miguel is reading a 338-page book. In the first 40 minutes he spends reading, he reads 52 pages. If he continues reading at the same rate, how many minutes will it take him to read the entire book?
Answer: 260 minutes.
Step-by-step explanation:
This represents the ratio between the minutes he reads and the pages he reads: 40 : 52
The book Miguel is reading is 338 pages long. Miguel also reads 52 pages in 40 minutes. You can divide 338 by 52, which is equal to 6.5.
If it takes Miguel 40 minutes to read 52 pages, then we can multiply that by 6.5. 40 x 6.5 = 260.
In conclusion, it will take Miguel 260 minutes to read the entire book, or 4 hours and 20 minutes.
Answer:
260 minutes
Step-by-step explanation:
40:52
x:338
338*40=52x
13,520/52
260:338

Simplify: (4 – 5) – (13 – 18 + 2).
Answer:
2
Step-by-step explanation:
(4 - 5) - (13 - 18 + 2)
According to PEMDAS, we should simplify the parentheses first.
= (-1) - (-3)
When you subtract a negative number, you are actually adding.
= -1 + 3
Now, add.
= 2

What is the equation of the horizontal line passing through (3, 8)?
Answer:
Y= -5
Step-by-step explanation:
If y always equals -5 then the x value will change but the y value will not. This means that the slope of the line is zero and will be parallel to the x axis, which is the horizontal line.

Elimination equations
9x - 4y = 19
4x+4y=20
The solution to the system of equations 9x - 4y = 19 and 4x + 4y = 20
is x = 3 and y = 2.
What are linear and non-linear functions?A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x - 2 depicts a linear function because it is a straight line in the coordinate plane.
Any function whose graph is not a straight line is said to be nonlinear.
Any curve other than a straight line can be a graph of it.
An example of a non-linear function is a quadratic function.
Given, Two linear equations in two variables 'x' and 'y',
9x - 4y = 19 and 4x + 4y = 20.
Now, Adding these two equations we have,
13x = 39.
x = 3 and hence y = 2.

WILL MARK BRAINLIEST WHOEVER ANSWERS FIRST :DD
Answer:
20. multiply both sides by 4, x= 24
21. multiply both sides by 7, y=21
22.multiply both sides by 5, z=20
23. multiply both sides by 6, p=12
24. multiply both sides by 2, r=8
Step-by-step explanation:
you want to get the variable alone (x,p,y, etc).
so if you are dividing the variable by a number you want to take the denomentator and multiply it by itself and then you have to multiply the same number to the number on the other side of the equation.
What is 15/20 closest to 0,1/2 or 1
Answer:
0.07 (7/100) is closer to 0.
1.150 (1150/1000) is closer to 1.
0.391 (391/1000) is closer to 1/2.
0.0999 (999/10,000) is closer to 0.
0.99 (99/100) is closer to 1.
0.599 (599/1000) is closer to 1/2.

What is a fraction?A fraction is a number written in the form a / b, where a and b are integers and b ≠ 0.
The number a is called as the numerator and b is the denominator.
The given fraction is 15/20.
It can be simplified as below,
Divide numerator and denominator by the common factor 5 as,
(15 ÷ 5)/(20 ÷ 5)
⇒ 3/4
The given fraction 3/4 is greater than zero and closest to 1.
Hence, the given fraction is closest to integer 1.

Andy is buying a car
he negotiated a 7% decrease on a £6 500 car
he will pay the full balance in 12 equal month payments
calculate the amount paid each month
Answer:
£503.75 per month
Step-by-step explanation:
7% decrease on a £6,500 car
= 7% of 6,500
= 7/100 * 6,500
= 0.07 * 6500
= £455
Amount of the car = £6,500 - £455
= £6,045
he will pay the full balance in 12 equal month payments
Amount paid each month = £6,045/12 months
= £503.75 per month
Answer:
7% decrease on a £6,500 car
= 7% of 6,500
= 7/100 * 6,500
= 0.07 * 6500
= £455
Amount of the car = £6,500 - £455
= £6,045
he will pay the full balance in 12 equal month payments
Amount paid each month = £6,045/12 months
= £503.75 per month
