Answer:4 hours
Step-by-step explanation:
I just did this question
By finding the quotient between distance and speed, we will see that they will meet after 4 hours.
In how many hours will they meet?First, we need to find the distance between them.
Ali starts on mile marker 3.Beth starts at mile marker 503.So the distance between them is:
D = 503mi - 3 mi = 500 mi
And we know that Ali travels with a speed of 60mph, while Beth travels with a speed of 65 mph.
Then the combined speed is:
S = 60mph + 65 mph = 125 mph
Remember the relation:
Speed*time = distance
Here we know the speed and the distance, so we can get the time:
T = D/S = 500 mi/ 125 mph = 4h
They will meet after 4 hours.

Calculate the surface area of an open cylinder measuring 35cm in diameter and 60cm high.
Answer:
6598.2 in^2
Step-by-step explanation:
Given data
Diameter= 35in
Radius= d/2= 35/2= 17.5in
Height = 60cm
The expression for the curve surface area of a cylinder is
CSA=2πrh
substitute
CSA= 2*3.142*17.5*60
CSA= 6598.2 in^2
Hence the CSA is 6598.2 in^2

Answer:
10 is the hypotenuse
Step-by-step explanation:
a² + b² = c²
Given:
a = 8
b = 6
Work:
a² + b² = c²
8² + 6² = c²
64 + 36 = c²
100 = c²

Answer: [tex]7,5.66,39^{\circ}[/tex]
Step-by-step explanation:
Given
[tex]IJ=9\\\angle I=51^{\circ}[/tex]
from figure, we can write
[tex]\Rightarrow \sin 51^{\circ}=\dfrac{HJ}{9}\\\\\Rightarrow HJ=9\sin 51^{\circ}=6.99\approx 7[/tex]
[tex]\Rightarrow \cos 51^{\circ}=\dfrac{HI}{9}\\\Rightarrow HI=9\cos 51^{\circ}\\\Rightarrow HI=5.66[/tex]
In right angle trianle, the sum of the remaining two angles is [tex]90^{\circ}[/tex]
[tex]\therefore 51^{\circ}+\angle J=90^{\circ}\\\Rightarrow \angle J=90^{\circ}-51^{\circ}\\\Rightarrow \angle J=39^{\circ}[/tex]

Answer: -5/12
Step-by-step explanation:
Data: 3/12-1/6-1/4-1/4=x
Step one, Find the common demoninator of the fractions
3/12-1/6-1/4-1/4 = 3/12-2/12-3/12-3/12
Reason: You can't subtract fractions that don't have the same denominatory so by finding the common demoninator you allow the problem to be solved.
Step two, Subtract
3/12-2/12= 1/12-3/12=-2/12-3/12=-5/12
Reason: You subtract fractions(With the same denominator) like normal numbers but you keep the denominator the same. When subtracted, the end result is -5/12 since subtracting a bigger number from a smaller number creates a negative.
Answer: -5/12

A ball is thrown into the air with an upward velocity of 40 ft/s. Its height h in feet after t seconds is given by the function \large h=-16t^2+40t. What is the ball's maximum height?
Answer:
[tex]h=25[/tex]
Step-by-step explanation:
From the question we are told that:
Velocity [tex]v=40fts[/tex]
The height h function
[tex]\large h=-16t^2+40t[/tex]
Generally time t is mathematically given by
[tex]h'=-32t+40[/tex]
[tex]-32t+40=0[/tex]
[tex]t=\frac{40}{32}[/tex]
[tex]t=1.25[/tex]
Therefore the ball's maximum height is given as
[tex]\large h=-16(1.25)^2+40(1.25)[/tex]
[tex]\large h=-16(1.25)^2+40(1.25)[/tex]
[tex]h=25[/tex]
A seventh-grade teacher asks her students a survey question. Which questions are appropriate for the teacher to ask her population? Select three options.
Answer:
The questions that are appropriate for the teacher to ask her population are:
How many hours of sleep do you get per night?
On average, how long does it take you to complete your homework?
What time do you leave for school in the morning?
Step-by-step explanation:
The survey is conducted among the seventh grade students so the valid question their teacher would have asked them is:
How many hours of sleep do you get per night?
On average, how long does it take you to complete your homework?
What time do you leave for school in the morning?
while the other two questions are invalid as it the students are young and they are not legal to vote.
also it is not necessary that they would arrive to school by car. Please mark the brainliest!
In a group of 32 pupils, 3 play the flute only. 13 play the piano only. 10 play neither instrument. A student is selected at random. What is the probability the student plays both instruments?
Answer:
18.75%
Step-by-step explanation:
Given that
There is a group of 32 pupils
3 play the flute only
13 play the piano only
And, 10 play neither instrument
We need to find out the probability the student plays both instruments
So
= (32 - 13 - 10 - 3) ÷ 32
= 6 ÷ 32
= 0.1875
= 18.75%
Answer:
6/32 or 3/16
Step-by-step explanation:
13 add 10 add 3 = 26
32-26=6
the total amount of children is 32 so the number is 6/32
you can then simplify it to 3/16

find the slope of line AB From the Given figures
please help me and solve him
Answer:
slope of AB = 0
Step-by-step explanation:
The slope of the x- axis OX = 0
Since AB is parallel to the x- axis and parallel lines have equal slopes, then
slope of AB = 0
Since, the line AB is parallel to X - axes, so every point on the the line AB will have equal Y - coordinates.
lets take it as Y ( y - coordinate is same )
slope :
=》
[tex] \dfrac{y2 - y1}{x2 - x1} [/tex]
but since y2 and y1 are equal, so
[tex] \dfrac{ Y - Y }{x2 - x1} [/tex]
=》
[tex] \dfrac{0}{x2 - x1} [/tex]
=》
[tex]0[/tex]

if each box represents 1 miles, what is the shortest distance from the school to the skate park.
The shortest distance between two points is a straight line.
Use the distance formula for points.
In the diagram, we are given two points:
(4,2) and (-3,0).
Let d = distance between the two points.
d = sqrt{(-3 -4)^2 + (0-2)^2}
d = sqrt{(-7)^2 + (-2)^2}
d = sqrt{49 + 4}
d = sqrt{53}
d = 2.2360679775
d = 2.2 miles
