Helen spent 7.75 to purchase 23 snack sized bags of chips (c) and pretzels (p). Chips cost 0.25 and pretzels cost 0.50. How much of each type of snack did she get?
Answer:
15 chips and 8 pretzels
Step-by-step explanation:
According to the problem, calculation of the given data are as follows,
Total spent = $7.75
Number of snacks = 23
Chips cost = $0.25
Pretzels cost = $0.50
Let number of chips = X
So, number of pretzels = 23 - X
So, we can calculate number of snacks by using following equation
0.25X + 0.50 ( 23 - X) = $7.75
0.25X + 11.50 - 0.50X = 7.75
0.25X - 0.50X = 7.75 - 11.5
-0.25X = -3.75
X = -3.75 ÷ -0.25 = 15
Hence, Number of chips = 15
Number of Pretzels = 23 - 15 = 8
A shipping container will be used to transport several 130-kilogram crates across the
country by rail. The greatest weight that can be loaded into the container is 26500
kilograms. Other shipments weighing 11400 kilograms have already been loaded into
the container. What is the greatest number of 130-kilogram crates that can be loaded
into the shipping container?
Answer:
Thebecks u
Step-by-step explanation:
its 93
The greatest number of 130-kilogram crates that can be loaded into the shipping container is 116.
What is subtraction?Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.
The weight that can be loaded on the container
= Total weight capacity of container - Weight that is already present on the container
= 26,500 kilograms - 11,400 kilograms
= 15,100 kilograms
Now, the number of crates that can be put in the container,
Number of crates
= Weight that can be loaded on the container / Weight of a crate
= 15,100 kilograms / 130 kilograms
= 116.1538 ≈ 116
Hence, the greatest number of 130-kilogram crates that can be loaded into the shipping container is 116.

Total number of students =. 40,140
During study:
Sample size = 210
Number of samples who speak 3 or more languages = 14
Proportion who speak 3 or more languages :
14 / 210 = 0.0666666
Applying the proportion to the total. Population :
0.0666666 * total number of students

a. 3/10
b. 1/4
c. 1/5
d. 1/6
e. 1/10
Answer:

Step-by-step explanation:
Calculate the frames of each month:
January = 350
February = 100
March = 250
April = 300
Solve
[tex]\frac{March}{Total} = \frac{250}{350 + 100 + 250 + 300} = \frac{250}{1000}[/tex]

SE TIENE UNA PARED PARA ENCHAPAR DE 5 METROS DE BASE X 2 METRS DE ALTURA , Y LOS BALDOSINES PARA ENCHAPAR TIENE 25CM DE ALTURA Y 10 CM DE BASE CUANTOS BALDOSINES SE NESECITARAN PARA ENCHAPAR LA PARED
Answer:
Se necesitan 400 baldosines para cubrir la pared.
Step-by-step explanation:
Primero debemos encontrar el área de la pared:
[tex] A_{p} = b_{p}*h_{p} [/tex]
En donde:
[tex] A_{p}[/tex]: es el área de la pared
[tex]b_{p}[/tex]: es la base de la pared = 5 m
[tex]h_{p} [/tex]: es la altura de la pared = 2 m
[tex] A_{p} = 5 m*2 m = 10 m^{2} [/tex]
Ahora debemos encontrar el área de los baldosines:
[tex] A_{b} = b_{b}*h_{b} [/tex]
[tex] A_{b} = 10 cm*25 cm = 250 cm^{2}*\frac{1 m^{2}}{(100 cm)^{2}} = 0.025 m^{2} [/tex]
Si un baldosin cubre 0.025 metros cuadrados de pared, para cubrir 10 metros cuadrados necesitamos:
[tex] N_{B} = \frac{1 B}{0.025 m^{2}}*10 m^{2} = 400 [/tex]
Por lo tanto, se necesitan 400 baldosines para cubrir la pared.

The table shows the relationship between the diameter in kilometers of an oil spill and the time in days. A quadratic function can be used to model this relationship.
What is the best prediction of the time required for the oil spill to reach the diameter of 10 km?
A) 147 days
B) 200 days
C) 205 days
D) 233 days
Answer:
205 is my answerrrrrrrrrrr
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 147 days. Then the correct option is A.
What is a quadratic equation?The quadratic equation is given as ax² + bx + c = y. Then the degree of the equation will be 2.
The table shows the connection between the width in kilometers of an oil slick and the time in days. A capability can be utilized to show this relationship.
The equation at (2.4, 1) will be given as,
2.4 = a (1)² + b (1) + c
2.4 = a + b + c ...1
The equation at (9.4, 2) will be given as,
9.4= a (2)² + b (2) + c
9.4 = 4a + 2b + c ...2
The equation at (21.1, 3) will be given as,
21.1 = a (3)² + b (3) + c
21.1 = 9a + 3b + c ...
Solve equations 1, 2, and 3 with the calculator, then we have
a = 2.35, b = -0.05, c = 0.1
Then the equation is given as,
y = 2.35x² - 0.05x + 0.1
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be
y = 2.35(10)² - 0.05(10) + 0.1
y = 235 - 0.5 + 0.1
y = 235.5
The value of y is nearer to the value of 233. Then the value of y will be 233 days.
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 233 days. Then the correct option is D.

28 students travel on a field trip. They bring a van that can seat 12 students. Elena and Kiran's teacher asks other adults to drive cars that seat 3 children each to transport the rest of the students.
Answer:
Step-by-step explanation:
Yes, she can use this inequality and it does matter since the number of cars that the inequality provides will need to be equal to or more than that number in order for all the students to be able to go. Therefore, if we apply the inequality it would give us the minimum number of cars needed (n) like so
12 + 3n > 28 ... subtract 12 on both sides
3n > 16 ... divide both sides by 3
n > 5 1/3
Since there can't be 1/3 of a car and the number of cars needed must be higher than 5 1/3 then we would need a total of 6 cars to take all of the children.
