Answer:
2 chefs and 13 customersStep-by-step explanation:
Let the number of chefs is x and the number of customers is y.
Regular rolls
Prepared 15x, eaten 2y, left 4Equation:
15x = 2y + 4 >>> (1)Vegetarian rolls
Prepared 20x, eaten 3y, left 1Equation:
20x = 3y + 1 >>> (2)We have a system.
Solve it by elimination, multiply the first one by 4 and the second one by 3:
15x*4 = 2y*4 + 4*4 ⇒ 60x = 8y + 1620x*3 = 3y*3 + 1*3 ⇒ 60x = 9y + 3Compare the equations:
8y + 16 = 9y + 39y - 8y = 16 - 3y = 13Substitute the value of y into first equation and solve for x:
15x = 2*13 + 415x = 30x = 2Answer:2 Chefs and 13 customers.

cost if Aria is riding for 2 miles? How much would a taxi ride cost that is m miles
long?
Answer:
Riding 2 miles = $6.50
Riding m miles: C = 1.25m + 4
Step-by-step explanation:
(1.25)*(2) + 4 = $6.50

Step-by-step explanation:
It is all about rounding.
To estimate the product, round each value to 1 significant figure. For example, 46.7 rounds to 50, and 31.7 rounds to 30. The estimate of the product will be the product of these rounded values: 50·30 = 1500.

The equivalent expression of (5ab)^3/30ab^-7 is 25 a^2b^10/6.
What is an expression?An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
here, we have
to determine the equivalent expression:
The expression is given as:
(5ab)^3/30ab^-7
Expand the numerator
(5ab)^3/30ab^-7
= 125 a^3b^3/30ab^-7
Divide 125 and 30 by 5
(5ab)^3/30ab^-7
=25 a^3b^3/6ab^-7
Apply the law of indices
(5ab)^3/30ab^-7
=25 a^(3-1) b^(3+7) /6
Evaluate the exponent
(5ab)^3/30ab^-7
=25 a^2b^10/6
Hence, the equivalent expression of (5ab)^3/30ab^-7 is 25 a^2b^10/6.

What is the slope of the line
Answer:
The slope = 2
Step-by-step explanation:
Slope is rise over run.
The line rises 2 units up for every 1 unit it moves right.
Thus, the slope would be 2/1, which is the same as 2.

whats is the difference between a factor and multiple
Answer:
a factor is a number that divides another number without leaving any remainder. , A multiple is a number that, when divided a certain of times by another number, no remainder is left.Step-by-step explanation:
Answer:
Main Differences Between Factor vs Multiple
Let us further discuss the difference between factor and multiple in the table below.
Basis of Comparison Factor Multiple
Definition It is a figure that gives a specific or definite outcome when it divides another figure It is the product of two whole numbers.
Results Less than or equal to such a specific figure Greater than or equal to the given figure.
Numbers of Result Limited Unlimited or continuous
Operation involved Division (÷) Multiplication (×)
Illustration If A divides B, A is factor of B If A is divisible by B and C, A is a multiple of B and C.
Difference Between Factor and Multiple: Conclusion
In conclusion, multiple vs factor concept is distinctive because the former uses multiplication (×) as a method of operation while latter uses division (÷). However, these two operations can be used together in a given equation or mathematical problem to get an expected outcome.
Though these two concepts are mostly taught in the elementary classes, they are inevitable in the arithmetic circus. One must be grounded in them and be sure of how they are applicable in every relevant equation. The good thing is that this guide has shown you their meanings, how to apply them, and the key discrepancies.

A rectangular pyramid has a height of 10 meters. If the sides of the base measure 3 meters and 5 meters, what is the volume of the pyramid
Answer:
the volume is 50
Step-by-step explanation:
The volume of a pyramid is found by using the formula V = lwh/3
If you multiply 3 5 and 10 you get 150
Dividing 150 by 3 gives you 50
Give the slope-intercept form of the equation of the line that is perpendicular to –7x – 8y = 12 and contains P(–3, 1)
Answer:
(-7/8)
Step-by-step explanation:
the line is -7x -8y =12
its slope = -(-7/-8)= -7/8
it passes through P(-3, 1)
(y-1)=(-7/8)(x+3)
y-1 = (-7/8)x - 21/8
y = (-7/8)x -13/8
The equation for line k can be written as 4x+7y=7. Line l includes the point (7,3) and is parallel to line k. What is the equation of line l?
Answer:
[tex]4x+7y=49[/tex]
Step-by-step explanation:
If you don't want to go through the slope-intercept form, you can easily see that two parallel line have their x and y coefficients in the same ratio, in our case 4:7. Let the new line be, then, [tex]4x+7y=k[/tex] and state that passes through our point: [tex]4(7)+7(3) = k \rightarrow k=49[/tex]

[First one, aka #13] is a
- If a 20-gallon bathtub is draining at a rate of 2.5 gallons, the max will be 20 gallons. Since it is water/etc, you cannot have negative water, so the least amount will be 0. We now have 0 ≤ ? ≤ 20
- What variable do we use? We are talking about gallons, so we will use g (gallons remaining) to get our answer of a, which is 0 ≤ g ≤ 20
[Second one, aka #11] is d
- I made the system
s - 18 = t
12s = 10t + 32
- Because one sport (s) has 18 less than one technology (t), so s - 18 = t. 12 sport (12s) has 32 more than 10 technology (10t) so if you add 32 to technology, you will get sport (12s = 10t + 32 )

Tyrell worked on
16 - 2(4 + 3x)
what do brackets mean ? they mean that this operation has to be done before everything else in the expression.
as this contains a variable, we cannot fully calculate it, true, but we need to keep this in mind and always treat the content of the brackets as one package.
so, whatever I do from the outside with one part of that package, I have to do also with all the other parts of that package.
so, the multiplication with -2 has to happen with both : 4 and 3x. not just with 4.
therefore, the correct simplification looks like
16 - 8 - 6x
8 - 6x or -6x + 8
Amelia multiplied correctly, but then made a mistake summing things up
10x - 3(4x + 1)

-. Mimi deposited $2,500
in the bank at a 4%
interest rate for 7 years.
What is the interest and the total
Answer:
The total is $3,725
and the amount earned in interest is $1,225
Step-by-step explanation:
$2500 multiplied by 7% = $175
$175 * 7years =$1,225
$1,225 (interest) + $2500 (starting amount) = $3,725
An airline gathers data on late departures and early arrivals over a month. It finds that the probability of a late departure is 12 percent, the probability of an early arrival is 27 percent, and the probability of both a late departure and an early arrival is 4 percent. Which equation shows how to correctly calculate the probability of a late departure or an early arrival? P(late departure or early arrival) = 0. 12 0. 04 P(late departure or early arrival) = 0. 12 0. 27 P(late departure or early arrival) = 0. 12 0. 27 â€" 0. 04 P(late departure or early arrival) = 0. 27 0. 04 â€" 0. 12.
Answer:
c
Step-by-step explanation:
The equation that shows how to correctly calculate the probability of a late departure or an early arrival is P(L∪E)=0.12+0.27-0.04.
Probability of late departure P(L) = 0.12
Probability of early arrival P(E) = 0.27
Probability of both a late departure and an early arrival P(L∩E)= 0.04
What is probability?Probability is the measurement of the likelihood of an event.
P(L∪E)=P(L)+P(E)- P(L∩E)
Where P(L∪E) is the probability of a late departure or an early arrival.
So, P(L∪E)=0.12+0.27-0.04
Hence, the equation that shows how to correctly calculate the probability of a late departure or an early arrival is P(L∪E)=0.12+0.27-0.04.

Consider the expression 8ab+3b+16-4a How many terms are there , How many factors are in the first term , which term is a constant ?
Answer:
First there are 4 terms. I think/believe that there are 3 factors in the first term. And the answer to the last question is 16 or term 3.
Step-by-step explanation:
I hope this helps, plz mark me as brainlyest anyways I hope you get a good score on your test!!
Answer:
a. There are 4 terms in the expression
b. There are 3 factors in the first term.
c. The constant is 16.
8ab + 3b + 16 - 4a
A term is any signed number, a variable, or a constant multiplied by a
variable or variables.
Therefore, the terms are 8ab, 3b, 16, and -4a. The terms are 4 in numbers.
The first term is 8ab .The first term has the factors 8 , a and b. This means the first term have 3 factors.
The term that is a constant is 16
