Using proportions, it is found that:
a) They can paint 2.8 pictures in one hour.
b) The rate per hour is of 131.2 magazines.
c) The unit rate is of 0.86 problems per minute.
d) He can make 92.5 tacos in one hour.
e) He walks 3.75 miles in one hour.
The code is of 148.79.
What is a proportion?A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.
Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.
A unit rate is given by amount or fraction divided by time. Hence, for item a, it is given as follows:
4/5/(2/7) = 4/5 x 7/2 = 2.8.
They can paint 2.8 pictures in one hour.
For item b, we have that:
328/2.5 = 131.2.
The rate per hour is of 131.2 magazines.
For item c, we have that:
15/17.5 = 0.86.
The unit rate is of 0.86 problems per minute.
For item d, we have that:
185/2 = 92.5.
He can make 92.5 tacos in one hour.
For item e, we have that:
0.75/0.2 = 3.75.
He walks 3.75 miles in one hour.
For the code, the letters are given as follows:
E = 3.75, B = 131.2, D = 92.5, A = 2.8, C = 0.86.
Hence the code is given by:
E(B - D) + (A + C) = 3.75(131.2 - 92.5) + (2.8 + 0.86) = 3.75(38.7) + 3.66 = 145.13 + 3.66 = 148.79.
The code is of 148.79.

Between which two perfect cubes does the cube root 141 lie
125 and 216 are two perfect cubes
How do I solve 9-2(p+1)=4(p-8)
Answer:
Step-by-step explanation:
First, distribute the -2 to the p and +1 in the parentheses.
9-2(p+1)=4(p-8)
9-2p-2=4(p-8)
Then on the other side do the same thing distributing the 4 to the p and -8.
9-2p-2=4(p-8)
9-2p-2=4p-32
Now isolate the variable p by adding 2p to each side
9-2p-2=4p-32
9-2=6p-32
From here you subtract 9 from 2 and then add 32 to both sides.
7=6p-32
39=6p
finally you divide both sides by 6 to get p.
39/6=p
6.5=p

In multiplication when bases are same, the powers are added. So the answer after simplifying is d) -24a^3b^7
Product of (3a^2b^4)*(-8ab^3)
Multiplication is one of the four basic arithmetic operations, alongside addition, subtraction, and division. Multiplication essentially means the repeated addition of groups of equal sizes. While solving multiplication problems, one-digit numbers can be multiplied in a simple way by using the multiplication tables, but for larger numbers, we split the numbers into columns using their respective place values, like ones, tens, hundreds, thousands, and so on.
The multiplication formula is expressed as, Multiplicand × Multiplier = Product; where:
Multiplicand: The first number (factor).
Multiplier: The second number (factor).
Product: The final result after multiplying the multiplicand and multiplier.
(3a^2b^4)*(-8ab^3)= -24a^3b^7

The length of a rectangle is 12 feet less than 6 times its width. If the perimeter of the rectangle is
312 feet, find the length and width of the rectangle.
If the perimeter of rectangle is 312 feet,
The length and width of the rectangle are 132 feet and 24 feet
let the width of the given rectangle be x feet
then as per the information provided in the question , the length of rectangle is 6x-12 feet
the parameter of the rectangle is the two times the sum of its length and breath = 2(l+ b)
We are already provided with the parameter of the rectangle as 312 feet
So, let us put the value of length and breath along with the parameter in the formula
312= 2( (6x-12) + x
312= 2( 6x-12 + x)
312= 2(7x-12)
312= 14x - 24
312+24 =14x
336=14x
therefore x= 24
Hence, the length and width of the rectangle are 132 feet and 24 feet

Find the equation of the line though the point (−4,−1) and perpendicular to the line y=25x+7. Write your answer in the form y=mx+b.
The equation of the line though the point (−4,−1) and perpendicular to the line y=25x+7 is y = -(1/25)*x - 21/25
How to find the equation of the line?
We want to find a line perpendicular to y = 25x + 7, then the slope of our line must be the inverse of the opposite of 25, this is:
a = -(1/25)
Then our line is something like:
y = -(1/25)*x + b
And we want this to pass through (-4, -1), then:
-1 =-(1/25)*-4 + b
-1 = 4/25 + b
-1 + 4/25 = b
-25/25 + 4/25 = b
-21/25 = b
We conclude that the linear equation is:
y = -(1/25)*x - 21/25

What is the Equation of a Line in Point-Slope Form?The equation, y - b = m(x - a), is the point-slope form of any given line where m is the slope of the line and any point on the line is given as (a, b).
Slope (m) = rise/run.
Find the slope (m) of the graph at the right.
Slope (m) = rise/run = 1 units/2 units
Slope (m) = 1/2.
Any possible equation of the line should have a slope of 1/2.
y - 2 = 1/2(x - 4), y - 2 = 1/2(x + 4), and y - 4 = 1/2(x - 2) are the only equations that has a slope of 1/2.
Using a point on the line, say (0, 3), substitute x = 0 and y = 3 into each of the three equations to check if the equation is true.
y - 2 = 1/2(x - 4)
3 - 2 = 1/2(0 - 4)
1 = -2 [not true]
y - 2 = 1/2(x + 4)
3 - 2 = 1/2(0 + 4)
1 = 2 [not true]
y - 4 = 1/2(x - 2)
3 - 4 = 1/2(0 - 2)
-1 = -1 [true]
Therefore, the only possible equation of the drawn line is: y - 2 = 1/2(x + 4)

An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin. Since there are no other possible outcomes and the coin is fair, the odds of both the outcomes, "heads" and "tails," are equally likely to occur. As a result, the probability of either outcome is half.

What is algebra ?
Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.
It is given that Tina needs to purchase a refrigerator as replacement for $1100.
The monthly periodic rate if balance is not paid by the second month = 1.2 %
The amount she paid by the second month = $500
The due amount is :
= 1100 - 500
= $600
This amount she decided to pay by end of fourth month or after two more months.
Let's assume the amount she had to pay now at the end of fourth month is x then it given by :
= 600 + ( 600 × [tex]\frac{1.2}{100}[/tex] × 2)
= 600 + ( 12 × 1.2 )
= 600 + 14.4
= $ 614.4
