Answer:
14:10 is 24 hours clock which only come in after noon that is 12
11:25 is a normal clock with remains normal before 12:00
Find the equation of the line whose graph passes through (5,3 ) and has slope 1 / 4.
Answer: y = 1/4x + 1.25 ?? OR y = -4x + 23
Step-by-step explanation:
y = mx + c
3 = 1/4 (5) + c
3 = 1.25 + c
-1.25 from both sides
c = 1.75
y = 1/4x + 1.75
----------------------------------
perpendicular gradient = -4
y = -4x + c
3 = -4(5) + c
3 = -20 + c
+20 to both sides
c = 23
y = -4x + 23

There are 800 students who attend Park Middle School. There are 1.5 times as many boys as there are girls. Set up the system of equations needed to solve this problem.
x is boys
y is girls
800=1.5x=y
Answer (the system of equations input doesn't work, so there is no brace):
x = 1.5y
x + y =800
Step-by-step explanation:
First, identify the vital information:
- 800 total students
- 1.5 times as many boys as girls
So, if x = number of boys and y = number of girls, we can agree that:
x = 1.5y
And because there are 800 kids in total, we can agree that:
x + y = 800
There are 320 girls and 480 boys. (see below)
Since you have the value of x, 1.5y, you can plug-in the value:
x + y = 800
1.5 + y = 800
2.5y = 800
y = 320 girls
Plug-in the y-value into the equation for the number of boys:
x = 1.5y
x = 1.5(320)
x = 480 boys
To double-check:
320 + 480 = 800 ☺

You have 6 pints of glaze. It takes 7/8 of a pint to glaze a bowl and 9/16 of a pint to glaze a plate.
a. How many bowls could you glaze? How many plates could you glaze?
b. You want to glaze 5 bowls, and then use the rest for plates. How many plates can you glaze? How much glaze will be left over?
c. How many of each object could you glaze so that there is no glaze left over? Explain how you found your answer.
The bowls use
pints of glaze and the plates use
The bowls use ( blank ) pints of glaze and the plates use ( blank ) for a total of 6 pints of glaze.
Answer:
a. How many bowls could you glaze?
6 bowls
How many plates could you glaze?
10 plates
b. You want to glaze 5 bowls, and then use the rest for plates.
How many plates can you glaze?
2 plates
How much glaze will be left over?
8/9 of glaze would be left
c. How many of each object could you glaze so that there is no glaze left over? Explain how you found your answer.
4 4/23 bowls and 4 4/23 plates
Step-by-step explanation:
We are told in the question
Number of pints of glaze = 6 pints
Number of pints to glaze a bowl= 7/8 of pint
Number of pints to glaze a plate = 9/16 of a pint
a.
How many bowls could you glaze?
7/8 pint = 1 bowl
6 pints = x
Cross Multiply
x = 6 pints/ 7/8
= 6 × 8/7
= 48/7
= 6.8571428571 bowls
We can only glaze whole numbers of a bowl, hence, we can only glaze 6 bowls
How many plates could you glaze?
9/16 pint = 1 bowl
6 pints = y
y = 6 pints/ 9/16
= 6 × 16/9
= 10.666666667 plates
We can only glaze whole number of a plate, hence, we can only glaze 10 plates
b. You want to glaze 5 bowls, and then use the rest for plates.
1 bowl = 7/8 pints
5 bowls = z
Cross Multiply
z = 5 × 7/8pints
= 4 3/8 pints of glaze would be used for bowls
How many plates can you glaze?
The rest is for plates, hence:
The amount of glaze left for plates is calculated as:
6 pints - 4 3/8
1 5/8 pints of glaze would be left over to glaze plates.
So therefore,
9/16 pints = 1 plate
1 5/8 pints =
= 2 8/9
Hence we can only glaze 2 plates
How much glaze will be left over?
2 8/9 pints - 2 pints
= 8/9 pints of glaze.
c. How many of each object could you glaze so that there is no glaze left over?
We have 6 pints of glaze
Number of pints to glaze a bowl= 7/8 of pint
Number of pints to glaze a plate = 9/16 of a pint
Let the number of each objects be represented by x
7/8 × x + 9/16 × x = 6 pints
= 4 4/23 bowls and 4 4/23 plates
The sum of -7 times a number and 8 times the sum of the number and 1 is the same as the number minus 7.
Answer:
[tex]\huge\boxed{No \ solutions}[/tex]
Step-by-step explanation:
Our first goal is to transform these words into numbers for an expression.
Let's break it down.
-7 times a number
We'll assume that the number is [tex]n[/tex]. -7 times a number can be represented as [tex]-7n[/tex].
8 times the sum of the number and 1
We can break this complex statement down.
8 times the sum of the number and 1
The sum of the number and 1 will be [tex]n+1[/tex]. 8 times that will be [tex]8(n+1)[/tex]. Since it says at the beginning the sum of, we add [tex]8(n+1)[/tex] to [tex]-7n[/tex].
[tex]-7n + 8(n+1)[/tex]
Is the same as the number minus 7.
"Is the same" means we use an equal sign. The number minus 7 will be [tex]n-7[/tex]. So we get [tex]-7n + 8(n+1)=n-7[/tex]
Now we can solve for n by reversing the equation until we have n isolated on one side.
[tex]-7n + 8n + 8 = n-7[/tex]
[tex]n + 8 = n-7[/tex]
[tex]8 = -7[/tex]
We end up with 8 = -7. This is not possible. Therefore, there are no real values of x that satisfy this equation.
Hope this helped!

A car is traveling at a rate of 35 meters per second. What is the car's rate in kilometers per hour? How many kilometers will the car travel in 5 hours?
round your answers.
Answer:
120km/h
600km in 5 hours.
Step-by-step explanation:
1000 meters is equal to 1 kilometer. 1 meter is equal to .001 kilometer.
You can set up an equation like this to solve for the car's rate in kilometers.
[tex]\frac{1 km}{1000 m} = \frac{x km}{35m}[/tex] or [tex]\frac{1000 m}{1000 km} = \frac{x m}{35km}[/tex].
Now crossmultiply either fraction to solve for x.
[tex]\frac{1 km}{1000 m} = \frac{x km}{35m}\\\frac{1 km}{1000 m}*35 = \frac{x km}{35m}*35\\\frac{35 km}{1000 m} = xkm[/tex]
The car is going at .035km/sec. Now we need to multiply this to get kilometers per hour. There are 60 seconds in a minute and there are 60 minutes in a hour.
[tex]\frac{35}{1000} * 60 * 60[/tex]
The car travels at 120km per hour.
Since we now know the rate in kilometers per hour. We can multiply the rate by 5 since the question asks how many kilometers the car will travel in 5 hours.
120 * 5 = 600
The car will travel 600km in 5 hours.

This season, the probability that the Yankees will win a game is 0.57 and the probability that the Yankees will score 5 or more runs in a game is 0.51. The probability that the Yankees win and score 5 or more runs is 0.44. What is the probability that the Yankees would score 5 or more runs when they win the game? Round your answer to the nearest thousandth.
The probability is 0.771.
The answer rounded to the nearest thousandth.
The probability that the Yankees would score 5 or more runs when they win the game can be calculated by using the formula for conditional probability. It can be determined by dividing the probability that the Yankees win and score 5 or more runs by the probability that the Yankees win.
The formula for conditional probability is:
Conditional Probability = P(A and B) / P(B)Where A and B are two events.
In this case, the two events are the Yankees win and the Yankees score 5 or more runs. So, the probability that the Yankees would score 5 or more runs when they win the game is:
P(Yankees score 5 or more runs | Yankees win) = P(Yankees win and score 5 or more runs) / P(Yankees win)Using the given values:
P(Yankees score 5 or more runs | Yankees win) = 0.44 / 0.57 = 0.771.
This means that when the Yankees win a game, there is a 77.1% chance that they would score 5 or more runs.
The answer is rounded to the nearest thousandth.

Suppose we express the amount of land under cultivation as the product of four factors:
Land = (land/food) x (food/kcal) x (kcal/person) x (population)
The annual growth rates for each factor are:
1. the land required to grow a unit of food, -1% (due to greater productivity per unit of land)
2. the amount of food grown per calorie of food eaten by a human, +0.5%
3. per capita calorie consumption, +0.1%
4. the size of the population, +1.5%.
Required:
At these rates, how long would it take to double the amount of cultivated land needed? At that time, how much less land would be required to grow a unit of food?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following annual growth rates:
land/food = - 1%
food/kcal = 0.5%
kcal/person = 0.1%
population = 1.5%
Σ annual growth rates = (-1 + 0.5 + 0.1 + 1.5)% = 1.1% = 0.011
Exponential growth in Land :
L = Lo * e^(rt)
Where Lo = Initial ; L = increase after t years ; r = growth rate
Time for amount of cultivated land to double
L = 2 * initial
L = 2Lo
2Lo = Lo * e^(rt)
2 = e^(0.011t)
Take the In of both sides
In(2) = 0.011t
0.6931471 = 0.011t
t = 0.6931471 / 0.011
t = 63.01 years
Land per unit of food at t = 63.01 years
L = Fo * e^(rt)
r = growth rate of land required to grow a unit of food = 1% = 0.01
L/Fo = e^(-0.01* 63.01)
L/Fo = e^(−0.6301)
= 0.5325385 = 0.53253 * 100% = 53.25%
Land per unit now takes (100% - 53.25%) = 46.75%
