How much will a person pay for 12.3 pounds of bananas at a price of $1.34 per pound? round to the nearest cent.
Answer:
16.48
Step-by-step explanation:
12.3 X 1.34 =16.482 16.482 is closer to 16.48 because 2 is not over 5 so it rounds under.
$16.48 will a person pay for 12.3 pounds of bananas at a price of $1.34 per pound.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given, Price of Bananas is $1.34 per pound.
Since,
1 pound of banana costs = 1.34
12.3 pounds of banana will cost = 1.34 * 12.3
12.3 pounds of banana will cost = 16.482
Therefore, the Price of 12.3 pounds of bananas is $16.82.

Which best describes the graph of the function f(x) = 4(1.5)x? The graph passes through the point (0, 4), and for each increase of 1 in the x-values, the y-values increase by 1.5. The graph passes through the point (0, 4), and for each increase of 1 in the x-values, the y-values increase by a factor of 1.5. The graph passes through the point (0, 1.5), and for each increase of 1 in the x-values, the y-values increase by 4. The graph passes through the point (0, 1.5), and for each increase of 1 in the x-values, the y-values increase by a factor of 4.
Answer:
The correct option is:
The graph passes through the point (0, 4), and for each increase of 1 in the x-values, the y-values increase by a factor of 1.5.
Step-by-step explanation:
The function given to us is:
f(x) = 4(1.5)ˣ
Substitute x = 0 in the given function:
f(0) = 4(1.5)⁰
f(0) = 4(1)
f(0) = 4
Which means that the graph pass through the point (0,4)
Now Substitute x = 1 in the given function:
f(1) = 4(1.5)¹
f(1) = 6
Substitute x =2 in the given function:
f(2) = 4(1.5)²
f(2) = 9
Divide the consecutive values:
f(2) / f(1) = 9/6 = 1.5
f(1) / f(0) = 6/4 = 1.5
Hence the values of y increase by the factor of 1.5
Answer:
B The graph passes through the point (0, 4), and for each increase of 1 in the x-values, the y-values increase by a factor of 1.5.

The number is even. It is more than 1 but less than 100. Is it greater than 20. It is less than 5×7. The sum of the digits is 6. Is it evenly divisible by 4
Answer:
24
Step-by-step explanation:
Alright so the number has to be above 20 and below 35.
It has to be even, so our options are 22, 24, 26, 28, 30, 32, 34
Since the sum of the digits has to be 6, the only number from that list that it can be is 24.
This works because 24 is also evenly divisible by 4 (6x4=24) so it fits all of the criteria.

A battalion of 880 people is made up of four companies. Each company is made up of five platoons. Each platoon contains four squads. If each company has the same number of people, as do each platoon and each squad, how many people are in each squad?
Answer:
11 people are in each squad.
Step-by-step explanation:
A battalion of 880 people is made up 4 companies.
880/4 = 220 people
which means 1 company is made up of 220 people.
Each company is made up of 5 platoons.
220/5 = 44
which means each platoon is made up of 44 people
Each platoon contains 4 squads
44/4=11
which means each squad contains 11 people.
therefore each squad contains 11 people.
andrea spent $40 at a shoe store. she bought a pair of shoes for $25 and 5 identical pairs of socks. how much was each pair of socks? write an equation to represent this situation. use x to represent the price of each pair of socks.
The equation representing this situation is 25 + 5x = 40, where x represents the price of each pair of socks.
To determine the price of each pair of socks, we can set up an equation based on the given information.
Let's assume that the price of each pair of socks is represented by x.
Andrea bought 5 identical pairs of socks, so the total cost of the socks is 5x.
Additionally, she bought a pair of shoes for $25.
Considering the total amount spent at the shoe store is $40, we can write the equation as follows:
25 + 5x = 40.
This equation represents the total cost of the shoes and socks equaling the amount Andrea spent.
To find the price of each pair of socks, we solve the equation for x.
First, subtract 25 from both sides:
5x = 40 - 25,
5x = 15.
Then, divide both sides by 5 to isolate x:
x = 15 / 5,
x = 3.
Therefore, each pair of socks costs $3.

45% of a 300ml drink is concentrated pineapple juice. The rest is water. Find the volune of water that must be added so that 40% of the drink is concentrated pineapple juice.
Answer:
37.5 mL
Step-by-step explanation:
If x is the volume of water, then:
(0.45)(300) + (0)(x) = (0.40)(300 + x)
135 = 120 + 0.40x
15 = 0.40x
x = 37.5
The volume of water that must be added so that 40% of the drink is concentrated pineapple juice will be 37.5 mL.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given;
45% of a 300ml drink is concentrated pineapple juice.
If x is the volume of water, then we get;
(0.45)(300) + (0)(x) = (0.40)(300 + x)
135 = 120 + 0.40x
15 = 0.40x
x = 37.5

Common household electric current is called alternating current because the current alternates direction within the wires. The voltage V in a typical 115-volt outlet can be expressed by the function V(t)=163 sin wt Upper V left parenthesis t right parenthesis equals 163 sine omega t
,
where omega=w
is the angular speed (in radians per second) of the rotating generator at the electrical plant and t is the time measured in seconds. It is essential for electric generators to rotate at precisely 60 cycles per sec.
How many times does the current oscillate in 0.30
sec?__times
Answer:
n = 18 cycles
Step-by-step explanation:
To know how many times does the current oscillates in the given time, you take into account that the number of oscillation can be calculated by using the following expression:
[tex]n=ft[/tex] (1)
f: frequency of the oscillation of the current
t: time = 0.30s
The frequency is the number of cycles per second, that is, f = 60 cycles/s
You replace the values of f and t in the equation (1):
[tex]n=(60\frac{cycles}{s})(0.30s)=18\ cycles[/tex]
In 0.30s the current oscillates 18 times
Kaleb changed the subtraction in the expression to adding the additive inverse. What was his error?
6-17-6+17
Kaleb reversed the order of the integers.
Kaleb took the additive inverse of the second integer.
Kaleb took the additive inverse of the first integer.
Kaleb replaced subtraction with addition.
Answer:
Kaleb took the additive inverse of the first integer.
Step-by-step explanation:
The subtraction: 6 - 17, can be changed to: 6 + (-17), adding the additive inverse (the minus sign of the subtraction changes to a plus sign, and 17 changes to its additive inverse, -17).
Kaleb transforms: 6 - 17, into: -6 + 17. He took the additive inverse of the first integer, instead of the second one.

Required:
Number of possible outcomes
This question represent selection; i.e. selecting candidates for job positions;
This question can be solved by using Permutations/Selection formula
Given that 3 man are to be selected from 14 men and 2 women from a total of 6 women
Let M represent Men and W represent Woman
Number of ways = M + W
Calculating M
[tex]M = nPr[/tex]
Substitute nPr with its formular
[tex]M = \frac{n!}{(n-r)!}[/tex]
Where n = 14 men and r = 3 applied
[tex]M = \frac{14!}{(14 - 3)!}[/tex]
[tex]M = \frac{14!}{11!}[/tex]
[tex]M = \frac{14*13*12*11!}{11!}[/tex]
[tex]M = 14*13*12[/tex]
[tex]M = 2184[/tex]
Calculating W
[tex]W = nPr[/tex]
Substitute nPr with its formula
[tex]W = \frac{n!}{(n-r)!}[/tex]
Where n = 6 men and r = 2 applied
[tex]W = \frac{6!}{(6-2)!}[/tex]
[tex]W = \frac{6!}{2!}[/tex]
[tex]W = \frac{6*5*4*3!}{2!}[/tex]
[tex]W = 6*5*4[/tex]
[tex]W = 120[/tex]
Recall that Number of ways = M + W
Number of Ways = 2184 + 123
