The value of cost he received in change is,
⇒ 55 cents
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Colin bought a postcard for 45 cents.
And, he gave the cashier $1.
Since, We know that;
1 dollar = 100 cents
Hence, The value of cost he received in change is,
⇒ 100 cents - 45 cents
⇒ 55 cents
Thus, The value of cost he received in change is,
⇒ 55 cents

What expression can you use to find 17 divided by 4/5?
A: 4/5 divided by 16
B: 16 divided by 5/4
C: 16 times 5/4
D: 4/5 times 16
Answer: B) 16 times 5/4
Step-by-step explanation:
16 divided by 4/5 = 20
16 x 5/4 = 20
When a whole number like 16 is divided by a fraction such as 4/5, you multiply it by the reciprocal (flipped version) of the fraction. What is the reciprocal of 4/5? It's 5/4. From there, you can solve each equation to make sure they are equivalent to check.
60 cars to 24 cars what is the decrease percentage
Answer:
It decreased 60%
Step-by-step explanation:
TO figure this out we must first find 1% of 60
60/100 = .6
Now we find the difference between 60 and 24
60 - 24 = 36
Now that we know how much it decreased we must now find out what percent 36 is of 60.
.6 x 60 = 36
So 36 out of 60 is 60%
So it decreased 60%

Rohit rode his bike 5 2/3
miles. Sarah rode her bike 5 1/5
miles. Write an inequality that compares the fractions. Explain in a sentence who rode a greater distance.
Answer:
as a decimal 5 2/3 would be 5.67 rounded to the nearest hundredth. As a decimal 5 1/5 5.2 to the nearest tenth.
Rohit rode his bike a greater distance because 5 2/3 is only 1/3 away, while 5 1/5 is 4/5 away.

Step-by-step explanation:
just took it
The periods when B = 0.5 and 2 are 4π and π, respectively
How to determine the period?The period of a sine function is calculated using:
T = 2π/B
When B = 0.5, we have:
T = 2π/0.5
T = 4π
When B = 2, we have:
T = 2π/2
T = π
Hence, the periods when B = 0.5 and 2 are 4π and π, respectively

A regular pentagon is shown. A regular pentagon has side lengths of 9.4 centimeters and a radius of 8 centimeters. What is the length of the apothem, rounded to the nearest tenth?
Answer:
6.5 cm
Step-by-step explanation:
The computation of the length of the apothem is shown below:
Given that
The side length is 9.4 centimeters
And, the radius is 8 centimeters
Now based on the above information
As per the attached figure
AB = 8 cm
BC = 9.4 ÷ 2 = 4.7 cm
Now apply the pythagoras theorem
AB^2 = BC^2 + AC^2
8^2 = 4.7^2 + AC^2
AC^2 = 41.91
AC = 6.47 cm
= 6.5 cm
Answer: D). 6.5 cm

Determine the equation of the line of best fit
First, calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
From the graph, we can have:
[tex](x_1,y_1) = (20,35)[/tex]
[tex](x_2,y_2) = (60,25)[/tex]
So, the slope is:
[tex]m = \frac{25 -35}{60 - 20}[/tex]
[tex]m = \frac{-10}{40}[/tex]
[tex]m = -\frac{1}{4}[/tex]
The equation is then calculated as:
[tex]y = m(x - x_1) + y_1[/tex]
[tex]y = -\frac{1}{4}(x - 20) + 35[/tex]
[tex]y = -\frac{1}{4}x + 5 + 35[/tex]
[tex]y=-\frac{1}{4}x+40[/tex]
Hence, the equation is: [tex]y=-\frac{1}{4}x+40[/tex]

Answer:
48 degrees
Step-by-step explanation:
1) Solve for x
Complementary angles add up to 90 degrees. Therefore, m<A + m<B is equal to 90:
[tex]A+B=90\\(2x+20)+(3x)=90[/tex]
Open up the parentheses
[tex]2x+20+3x=90\\5x+20=90[/tex]
Subtract 20 from both sides
[tex]5x+20-20=90-20\\5x=70[/tex]
Divide both sides by 5
[tex]\frac{5x}{5} =\frac{70}{5} \\x=14[/tex]
Therefore, x is equal to 14.
2) Determine angle A
[tex]A=2x+20[/tex]
Substitute x with 14
[tex]A=2(14)+20\\A=28+20\\A=48[/tex]
Therefore, the measure of angle A in degrees is 48 degrees.

A school group is raising money for a trip. The group needs $450 for travel and $325 for food. They have 6 weeks to raise money selling $1 candy bars.
What is the least number of candy bars the group needs to sell each week to afford the trip?
Answer:
Step-In total, the amount of money they will need to raise is:
= 450 + 325
= $775
by-step explanation:
They have 6 weeks to raise this money so the amount they have to raise per week is at least:
= 775/6
= $130
The candy bars cost $1 each. They will therefore have to sell a minimum of 130 candy bars each week to afford the trip.
