Step-by-step explanation:
Resolviendo un sistema de ecuaciones, veremos que se juntaron 24 sobres de salsa.
¿Como resolver un sistema de ecuaciones?
Vamos a definir las variables:
x = número de estudiantes que lleva salsay = número de estudiantes que lleva tallarines.Sabemos que hay 30 estudiantes, así que:
x + y = 30
Y sabemos que hay un total de 42 productos, entonces tendremos que:
2x + y = 42
(el factor 2 que multiplica a x es por que cada uno de esos estudiantes lleva 2 sobres de salsa).
Entonces tenemos el sistema de ecuaciones:
x + y = 30
2x + y = 42
Para resolverlo, primero aislamos una de las variables en una de las ecuaciones, yo voy a aislar y en la primer ecuación:
y = 30 - x
Ahora reemplazamos eso en la otra ecuación:
2x + (30 - x) = 42
Y podemos resolver esto para x:
2x + 30 - x = 42
x = 42 - 30 = 12
x = 12
Es decir, 12 estudiantes llevaron sobres de salsa. Y cada uno de ellos lleva 2 sobres, entonces se reunieron 12*2 = 24 sobres de salsa.

The area of a square can be found using the equation A = s, where A is the area and s is the measure of one side of the square.
Match the equation for how to solve for the side length of a square to its description.
A square has an area of 227 in^2?
Answer:
s = √227 in
Step-by-step explanation:
A = s²
Where,
A = Area of a square
s = side length of the square
Find the side length of a square with area of 227 in²
A = s²
227 in² = s²
Find the square root of both sides
√227 in² = √s²
√227 in² = s
s = √227 in
Answer:
s = √227 in

A 10 ft by 10 ft square garden contains a large walking path through the diagonal what is the area of the walking path shown in the grey above
Answer:
64 ft^2
Step-by-step explanation:
Area of shaded part = area of a square = 2 x area of a triangle
area of a square = length^2
10^2 = 100 ft^2
Area of a triangle = (1/2) x base x height
1/2 x 6 x 6 = 18 ft^2
area of shaded part = 100 - 2x 18 = 64 ft^2

Answer:
Option 1: y + 5 = ½(x - 2)
Step-by-step explanation:
First, you need to find the slope. the formula to find the slope from two points is [tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex] and if you plug in the points it will be [tex]\frac{-4 - (-5)}{4 - 2}[/tex] which is [tex]\frac{1}{2}[/tex].
point-slope form is [tex]y - y_{1} = m(x - x_{1})[/tex]. m is slope and x₁ and y₁ is (2, -5).
plugging in the numbers will be y + 5 = ½(x - 2)
El promedio del 5 personas $ 20 si ingresan 3 personas con promedio de $ 60 ¿ cual es promedio del dinero de las personas
Answer:
El promedio de dinero de las personas es de $35 cada uno.
Step-by-step explanation:
Dado que el promedio del dinero de 5 personas es de $20 cada uno, para determinar, si ingresan 3 personas con promedio de $60 cada uno, cuál es promedio del dinero de las personas , se debe realizar el siguiente cálculo:
((5 x 20) + (3 x 60)) / 8 = X
(100 + 180) / 8 = X
280 / 8 = X
35 = X
Por lo tanto, el promedio de dinero de las personas es de $35 cada uno.
A library has 12,500 fiction books and 19,000 nonfiction books.
* Currently, 2/5 of the fiction books are checked out.
* Currently, 2/5 of the non fiction books are checked out.
* Of the books checked out, 1/10 are due back this week.
How many books are due back this week?
Question 1 options:
12,600
5,000
1,260
7,600
Answer:
1,260 books (or C)
Step-by-step explanation:
1. 2/5 of fiction (12,500) are out, so 5,000 are out
2. 2/5 of non-fiction (19,000) are out, so 7,600 are out
3. Total books checked out are 12,600
4. 1/10 of checked out books are due this week, so 1,260 books (10%)
Total number of books out of 12,500 fiction books and 19,000 non fiction books that are due back this week is 1,260
What is a fraction?
When a whole number is divided by a natural number we get a fraction as a result. 1/3 , 4/9 ,-3/5 are some examples of fractions. The number above the divisor sign are called numerator and the number below the divisor sign are called denominator.
Given, total number of fiction books= 12,500
And total number of non-fiction books = 19,000
Therefore, total number of fiction books that are checked out
= (2/5)×12,500=5,000
Total number of non-fiction books that are checked out = (2/5)×19,000
=7,600
Therefore, total number of fiction and non fiction books that are checked out = 5,000+7,600=12,600
Now 1/10 of of checked out books are due back.
Thus, number of books that are due back=(1/10)×12,600
=1,260.
Hence, total number of books that are due back this week is =1260

Answer:
The new coordinates are ( - 4, 5).
Step-by-step explanation:
P = (5, 4)
angle of rotation, A = 270 degree counter clock wise
x = 5 and y = 4
The new coordinates are
x' = x cos A + y sin A
y' = y cos A - x sin A
So,
x' = 5 cos 270 + 4 sin 270 = 0 + 4 (-1) = - 4
y' = 4 cos 270 - 5 sin 270 = - 5 (-1) = 5
So, the new coordinates are ( - 4, 5) .
The ages of trees in a forest are normally distributed with a mean of 25 years and a standard deviation of 5 years.
Complete question is in comment section :
Answer:
68%
Step-by-step explanation:
Mean = 25
Standard deviation = 5
The percentage of trees between 20 and 30
20 trees = 1 standard deviation below the mean ; mean - 1(standard deviation)
25 - 5 = 20
30 trees = 1 standard deviation above the mean ;
Mean + 1(standard deviation) ;
25 + 5 = 30
This means, 20 and 30 lies ±1 standard deviation from the mean which according to the empirical rule is 68%

Every day, Bridgette's burrito stand uses 7/10 of a bag of tortillas. How many days will 6 3/10 bags of tortillas last?
Answer:
Number of days bags of tortillas will last = 9 days
Step-by-step explanation:
Total bags of tortillas =6 3/10
Bag of tortillas used per day = 7/10
How many days will 6 3/10 bags of tortillas last?
Number of days bags of tortillas will last = Total bags of tortillas / Bag of tortillas used per day
= 6 3/10 ÷ 7/10
= 63/10 × 10/7
= 63*10 / 10*7
= 630/70
= 9
Number of days bags of tortillas will last = 9 days
