Ashley’s school took a field trip. A total of 32 vehicles were needed for the trip. Some students took the bus, and some students car-pooled. There were 27 people on each bus and 3 people in each car. 408 people altogether attended the trip. How many buses and cars were needed for the trip?
Answer:
19 cars
13 buses
Step-by-step explanation:
We have a system of equations as follows
X + y = 32 -----1
3x + 27y = 408 ----2
x = car
y = bus
From equation 1
x + y = 32
x = 32 - y ---- 3
We put equation 3 into equation 2
3(32-y) + 27y = 408
96y -3y + 27y = 408
96 + 24y = 408
24y = 408 - 96
24y = 312
Divide through by 24 to get the value of y
Y = 312/24
Y = 13
We put the value of y in equation 3
x = 32 - 13
x = 19
So 19 cars would be needed for the trip and also 13 buses would also be needed
is the graph of the function shown in the graph below one to one? why?
In accordance with functional theory, definition of functions and kinds of functions, the function is not injective but surjective. (Correct choice: C)
Does represent the picture of the function an injective or surjective function?
In accordance with functional theory, functions are relations in which each element of the domain is related to only one element of the range. There are three kinds of functions: (i) Injective - Each domain element is related to one distinct element of the range, (ii) Surjective - There are at least two domain elements that are related to an element of the range, (iii) Bijective - The function is both injective and surjective.
Based on all these information, we conclude that the given function has at least two values of the x-axis (domain) related to one value of the y-axis (range). In a nutshell, the function is not injective but surjective. (Correct choice: C)

How can you use the distributive property to rewrite 15p+10q as a product?
Answer:
Both of those terms are divisible by 5, so you could express it also as
5(3p + 2q)
The equivalent expression is [tex]5(3p+2q)[/tex].
Important information:
The given expression is [tex]15p+10q[/tex].We need to find the equivalent expression by using the distributive property.
Distributive property:According to the distributive property:
[tex]a(b+c)=ab+ac[/tex]
The given expression can be written as:

yoko made $231 for 11 hours of work. At the same rate, how much would she make for 8 hours of work.
Answer:
Step-by-step explanation:
If Yoko made 231 dollars in 11 hours, it means that she makes
231/11=21 dollars per hour
in 8 hours
8*21=168 dollars in 8 hours
Answer:
168
Step-by-step explanation:
We need to find how much money she makes in one hour. Then multiply that by 8.
231 ÷ 11 = 21
21 × 8 = 168
Select the correct answer. A basketball team played 15 games and won 80% of them. If the team expects to play 30 games in all, how many more games must it win to finish the season with a 90% winning percentage? O A 12 B. 14 Ос. D. US
Answer:
12 more games
Step-by-step explanation:
15 + 12 = 27
27 is 90% of 30 , so they need to win 12 more games but 27 overall out of the 30
30 = 100%
27 = x
x = 27×100%/30
x = 2700%/30
x = 90%
A farmer raises only ducks and pigs. There are 55 animals in all on his farm, and 146 legs.
Find the number of ducks and pigs on his farm by setting up and solving a system of equations.
Define the variables
Equations
Show all work
Answer:
Number of ducks = 37
Number of pigs = 18
Step-by-step explanation:
Let,
x be the number of ducks
y be the number of pigs
According to given statement;
x+y=55 Eqn 1
2x+4y=146 Eqn 2 (As ducks will have 2 legs and pigs will have 4)
Multiplying Eqn 1 by 2
2(x+y=55)
2x+2y=110 Eqn 3
Subtracting Eqn 3 from Eqn 2
(2x+4y)-(2x+2y)=146-110
2x+4y-2x-2y=36
2y=36
Dividing both sides by 2
[tex]\frac{2y}{2}=\frac{36}{2}\\y=18[/tex]
Putting y=18 in Eqn 1
x+18=55
x = 55-18
x = 37
Hence,
Number of ducks = 37
Number of pigs = 18

I need help with this question, in the picture.
Answer:
34 degrees
Step-by-step explanation:
34 degrees
the angle is 90 degrees
90-56=34
======================================================
Explanation:
Refer to the diagram below. I've added the variable y as the base angles to the isosceles triangle on the left.
Recall that the angles opposite the congruent sides are the base angles. The base angles of any isosceles triangle are the same measure.
Let's solve for y
y+y+56 = 180 .... all angles in a triangle add to 180
2y+56 = 180
2y = 180-56
2y = 124
y = 124/2
y = 62
I've also added the variable z, which is adjacent to one of the y angles.
Since y and z combine to form a straight angle, this means the two angles add to 180
y+z = 180
z = 180-y
z = 180-62
z = 118
Now focus on the isosceles triangle on the right. It has angles x, x, and z = 118.
x+x+z = 180
x+x+118 = 180
2x+118 = 180
2x = 180-118
2x = 62
x = 62/2

Internetlivestats.com reported in December 2017 around 41% of the world population has an Internet connection today. If there are
3,062,263,517 users, what is the world population? (Round your answer to the nearest whole number.)
Answer:
World population = 7,468,935,407
Step-by-step explanation:
Given that:
Percent of people who have internet connection = 41%
Number of people who have internet connection = 3,062,263,517
Let,
x be the world population.
41% of x = 3062263517
[tex]\frac{41}{100}x=3062263517\\[/tex]
0.41x = 3062263517
Dividing both sides by 0.41
[tex]\frac{0.41x}{0.41}=\frac{3062263517}{0.41}\\x=7468935407[/tex]
Hence,
World population = 7,468,935,407

Subtract 2 from each side
2+3x-2 < 8-2
3x<6
Divide each side by 3
3x/3 <6/3
