A line has a slope of 1/4 and passes through the point (4,8). Write the equation of the line in slope intercept form.
Answer:
y = 1/4x +7
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
y = 1/4 x +b
Substitute the point into the equation
8 = 1/4(4) +b
8 = 1 +b
Subtract 1 from each side
8-1 =b
7 =b
y = 1/4x +7
A homeowner's backyard is a rectangle with width 18 yards long and length 16 yards long. They plan to put in a square pool with side length 5 yards long in the backyard and then want to put tile in the rest of the entire backyard. How much tile do they need to buy?
Answer:
Step-by-step explanation:
Given the dimension of the homeowner's backyard to be width 18 yards long and length 16 yards long, the area of the rectangular backyard id expreesed as;
Area of rectangle = Length * Width
Area of the rectangular backyard = 18yards * 16yards
Area of the rectangular backyard = 288yards²
If they plan to put in a square pool with side length 5 yards long in the backyard, the area of the pool = 5yd*5yd = 25yd²
The remaining area that will contain the tiles = Area of the rectangular backyard - area of the pool
The remaining area that will contain the tiles = 288yd² - 25yd² = 263yd²
Note that we cannot determine the amount of tiles they need to buy since we are not given the dimension of each tile to use. The area needed for the tiles for the rest of the backyard is therefore 263yd².
Amount of tiles needed to buy can be expressed as 263/dimension of a tile.

Answer:
see below (I hope this helps!)
Step-by-step explanation:
p² = 4x² * (q(1 + r² / y²) / S)
p²S = 4x² * q(1 + r² / y²)
p²S / 4x²q = 1 + (r² / y²)
p²S / 4x²q - 1 = r² / y²
y² = r² / (p²S / 4x²q - 1)
y = √( r² / (p²S / 4x²q - 1) = √(r²4x²q / (p²S - 4x²q))
Four times the sum of half a number and 6 is 48
Answer:
The number is 12Step-by-step explanation:
Let the number be x
Half a number is written as 1/2x
So we have
Four times the sum of half a number and 6 is 48 is written as
[tex]4( \frac{1}{2} x + 6) = 48 \\ 2x + 24 = 48 \\ 2x = 48 - 24 \\ 2x = 24[/tex]
Divide both sides by 2
That's
[tex] \frac{2x}{2} = \frac{24}{2} [/tex]
We have the final answer as
x = 12Hope this helps you

What is the missing exponent?
Answer:
0
Step-by-step explanation:
( 2x^2 y^m) ^6 = 64 x^12
We are interested in the y variable
The y on the right is not there so we can write it as y^0
y^m^6 = y^0
We know that a^b^c = a^(b*c)
y^(m*6) = y^0
The bases are the same so the exponents have to be the same
6m =0
m=0
The missing exponent is 0
Compare and contrast natural numbers and rational numbers.
Natural numbers are strictly only plain numbers like no percents or integers, such as 1, 2, 3, 4, 5, 6 etc. Natural numbers are whole numbers and positive, so 0 would not be considered natural since it is not positive or negative
Rational numbers are numbers like 1, -100, .33, -10000, 2.4, etc it can be ALMOST anything, rational numbers fit every category but one IRRATIONAL
Irrational numbers are numbers like pie (3.145.......) it goes on forever and ever if the number never stops and repeats its called a repeating decimal, (HUGE TIP, IF YOU CAN MAKE IT A FRACTION IS IS ALMOST ALWAYS RATIONAL)
A computer downloads 30 megabits per second for "t" seconds. Write an
equation to represent the number of megabits, m, downloaded.
Answer:
M = 30t
Step-by-step explanation:
Given that a computer downloads 30 megabits per second for "t" seconds. That is, the rate at which the computer downloaded it is 30 megabits/second
Where time = t seconds
To Write anequation to represent the number of megabits, m, downloaded,
Rate = megabits/ time
Where
Rate = 30
Megabits = m
Time = t
Therefore, substitute all into the formula
30 = m/t
Make m the subject of formula
M = 30t
The equation is m = 30t

Water flows through a pipe at a rate of 9 quarts every 3.5 years. Express this rate of
flow in cups per day. Round your answer to the nearest hundredth.
Answer:
0.01 rate per dayStep-by-step explanation:
Given that the water flow through a pipe occrs a a rate of 9quarts every 3.5 years, he rate of flow in cups per year will be expresssed as;
9quartz = 3.5years
x quartz = 1 year
cross multiply
9quarts * 1 = 3.5 years * x
9 = 3.5x
x = 9/3.5
x = 2.57142 years
Hence the rate flow of cup per year will be 2.57 years. But since the question asked us to look for the rate of flow per day, we will divivde 2.57 by 365days.
The rate of flow in cups per day = 2.57/365 = 0.00704rate per day
≈ 0.01 rate per day to the nearest hundredth

Melinda worked 6.5 hours at her job. She makes $9.50 per hour. How much money did she earn for the day ?
Answer:
$61.75
Step-by-step explanation:
Hello,
If Melinda earns $9.50 per hour and she worked 6.5 hours, then her earnings for that day was $61.75.
This is simply the product of $9.50 * 6.5 = $61.75.
This assumption of earnings doesn't include tax reductions, unless her hourly pay includes those.

Two kids at a summer camp, Tina and Winston, are competing in a potato sack race. Tina is younger, so she is given a head start of 33 meters. When the race starts, Tina hops at a rate of 1 meter per second, and Winston hops 4 meters per second. Eventually, Winston will overtake Tina. How long will that take? How far will Winston have to hop? It will take ___ seconds for Winston to hop ___ meters and catch up to Tina.
Answer:
It will take Winston 11 seconds to hop 44 meters and catch up to Tina
Step-by-step explanation:
Set up an equation where x represents the number of seconds:
Tina will be represented by s + 33 since she goes 1 m/sec and she has a 33 meter head start, and Winston will be 4s. We need to find when Winston will catch up, so we need an equal sign.
s + 33 = 4s
Solve for s:
s + 33 = 4s
33 = 3s
11 = s
= 11 seconds
Then, plug in 11 as s to find how many meters he will go:
s + 33
11 + 33 = 44
= 44 meters

The ratio of the number of boys to the number of girls on the swim team is 4:2. If there are 24 athletes on the swim team, how many boys than girls are there?
Answer:
We have 8 more boys than girls on the swim team.
Step-by-step explanation:
The ratio of boys to girls on a swim team is represented as:
4 : 2
Total number of athletes is given as 24
Total ratio is given as:
4 + 2 = 6
Step 1
We find the number of boys and girls
Number of boys = 4/6 × 24 = 16 boys.
Number of girls = 2/6 × 24 = 8 girls.
Therefore, since we have 16 boys and 8 girls on the swim team, we have 8 more boys than girls on the swim team.

Linda Gramham's Cinnamon Sugar Graham Cupcake recipe for 36 cupcakes requires 1 1/4 cups of sugar. How much sugar is required for 900 cupcakes? Reduce to lowest terms.
Answer:
31.25 or 31 1/4 cups
Step-by-step explanation:
1 1/4 = 36
x = 900
=> 5/4 = 36
x = 900
Cross multiply
=> 5/4 * 900 = 36 * x
=> 4500/4 = 36x
=> 1125 = 36x
=> 1125 / 36 = 36x / 36
=> 31.25 = x
31.25 = 31 1/4
So, 31.25 or 31 1/4 cups are required for 900 cupcakes.
[tex]\frac{125}{4}=31\frac{1}{4}[/tex] cups of sugar is required for 900 cupcakes.
First, it is convenient to convert the mixed fraction corresponding to the time to improper. To do this, the integer is multiplied by the denominator, to which the numerator is added. Divide this result by the denominator. The denominator of the improper fraction will be the same as the mixed number had. In summary:
[tex]a\frac{b}{c}=\frac{c*a+b}{c}[/tex]
In this case:
[tex]1\frac{1}{4}=\frac{4*1+1}{4}[/tex]
Solving:
[tex]1\frac{1}{4}=\frac{4+1}{4}[/tex]
[tex]1\frac{1}{4}=\frac{5}{4}[/tex]
On the other side, the rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other) , the direct rule of three must be applied.
To solve a direct rule of three, the following formula must be followed, where a, b and c are known and x is the value to be calculated:
a ⇒ b
c ⇒ x
So:
[tex]x=\frac{cxb}{a}[/tex]
In this case, the rule of three can be applied as follows: Linda Gramham's Cinnamon Sugar Graham Cupcake recipe for 36 cupcakes requires [tex]1\frac{1}{4}=\frac{5}{4}[/tex] cups of sugar. If 900 cupcakes are made, how much sugar is required?
36 cupcakes ⇒ [tex]\frac{5}{4}[/tex] cups of sugar
900 cupcakes ⇒ x
Then:
x= (900 cupcakes× [tex]\frac{5}{4}[/tex] cups of sugar)÷ 36 cupcakes
Solving:
x= [tex]\frac{125}{4}[/tex] cups of sugar
In summary,[tex]\frac{125}{4}=31\frac{1}{4}[/tex] cups of sugar is required for 900 cupcakes.
