Last month you purchased 6 individual songs and 1 albums for a total of $21.99.
This month you spent a total of $44.97 on 4 individual songs and 3 albums.
How much does each song and album cost
Answer:
Song =$1.50 Album =$12.99
Step-by-step explanation:
Lets assume Individual songs = x
albums=y
6x + y = 21.99-------- y= 21.99- 6x
4x + 3y= 44.97
Replace y in the second equation
4x+ 3(21.99-6x) = 44.97
4x +65.97- 18x = 44.97
14x= 21
x = 1.50
y= 21.99- (6*1.50)
= 12.99

-0.753Step-by-step explanation:
Given
log₃4 ≈ 1.262 and log₃7 ≈ 1.771To find
log₃(7/16)Solution
log₃(7/16) = log₃7 - log₃16 = log₃7 - 2log₃4 =1.771 - 2*1.262 = -0.753So

The circumference of a circle is 9.04cm.
Find the length of the diameter.
Give your answer rounded to 2 DP.
The circumference of a circle is 9.04 cm. Find the length of the diameter.
Solution:-Let the radius of a circle be r cm.
We know the formula of circumference of a circle is 2πr.
ATQ ,
2πr = 9.04
2 × [tex] \frac{22}{7} [/tex] × r = 9.04
[tex] \frac{44}{7} [/tex] × r = 9.04
r = [tex] \frac{9.04 \: × \: 7}{44} [/tex]
r = [tex] \frac{63.28}{44} [/tex]
r = 1.438
Now, as we have to find the length of the diameter ,
So, we know, Diameter (d) = 2 × radius (r)
[tex] \therefore [/tex] d = 2r
Hence, d = 2 × 1.438 ( r = 1.438 )
d = 2.876
d = 2.88 ( approx )
The length of the diameter is 2.88 cm. [Answer]need help thank u

What is the slope represented in the table ?
Answer:
slope:2
Step-by-step explanation:
Slope is rise/run, or change in y/change in x.
With that being said, we only need two points to solve this.
Let's take the points (0,7) and (1,9)
The formula for finding the slope from two points is m=(y2-y1)/(x2-x1).
M is the slope.
y2 would be the y-value of the second point,9. y1 would be the y-value of the first point, 7.
x2 would be the x-value of the second point, 1. x1 would be the x-value of the first point, 0.
Plugging those values in to the formula, we get m=(9-7)/(1-0)
Simplifying, we get m=2/1, which is m=2.
It has the same slope as y=5x+3 and passes through (1, 5).
Answer:
y=5x
Step-by-step explanation:
Because it has the same slope, both equations must have 5x as their slope. The 2 equations are not going to have the same y intercept, so the +3 can be ignored and replaced with b. You want to plug in (1,5) into you new equation of y=5x+b, to get 5=5(1)+b. Multiply 5 by 1 to get 5, and then subtract 5 from both sides, which gives you 0=b. This means that the y intercept is the origin, so your new equation is y=5x

Answer:
x = 5, y = 2.5
Step-by-step explanation:
Because the original image is scaling down 4, it means all of the values of the shape will be scaled down, or divided by 4.
20, which divided by 4, will make x equal 5.
10, which divided by 4, will make y equal 2.5
In October Sally drove 560 miles in her car.
The car travelled 34.5 miles for each gallon of petrol used.
Petrol cost £1.08 per litre.
1 gallon = 4.55 litres.
Work out the cost of the petrol the car used in October
Answer: £80
Step-by-step explanation:
First, we need to calculate the number of gallons used by Sally. This will be:
= 560 / 34.5
= 16.23 gallons
Since 1 gallon = 4.55 litres, we calculate the number of liters and this will be:
= 16.23 × 4.55
= 73.85 liters
Since Petrol cost £1.08 per litre, the cost of the petrol will be:
= £1.08 × 73.85
= ££79.758
= £80 approximately

Answer:
Student C wrote the correct inequality
the inequality will be less than or equal to since we want to spend (exactly) 300 or less. We only buy one jacket for 60 dollars so it will be added seperately to the total number of jackets. We are buying multiple jackets and each jacket costs $40. P = # of pants. So the inequality will look like
60 + 40P (less than or equal to symbol) 300

what are all possible values for x in the equation x^3=375?
can you please solve this step by step?
will give brainliest
Answer:
[tex]x=5\sqrt[3]{3}[/tex] or 7.21
Step-by-step explanation:
x³ = 375
You have to take the square root and have the index 3:
You have to have the index 3 because x is cubed and you have to get rid of the cubed sign since a normal square root is for when the exponent is 2:
[tex]\sqrt[3]{x^3} =\sqrt[3]{375} \\x=5\sqrt[3]{3}[/tex]

Kurt and Maria's high school is having a newspaper drive.The goal is to collect 3,585 pounds of newspapers. So far, 21% of the goal has been reached. Kurt estimated the number of pounds of newspapers collected by finding 10% of 3,600 and then multiplying the result by 2. Maria estimated the number of pounds of newspapers collected by finding One-fifth of 3,600.
Options:
Who is right, and why?
a. Neither Kurt nor Maria is right, because 3,500 should be used instead of 3,600.
b. Kurt is right, because finding 1/5 of 3,600 is not a good way to approximate 21% of 3,585.
c. Maria is right, because finding 10% of 3,600 and multiplying the result by 2 is not a good way to approximate 21% of 3,585.
d. Both Kurt and Maria are right, because 3,585 should be rounded up to 3,600, and 21% of this amount can be approximated by either finding 10% of 3,600 and multiplying the result by 2 or by finding 1/5 of 3,600.
Answer:
d. Both Kurt and Maria are right, because 3,585 should be rounded up to 3,600, and 21% of this amount can be approximated by either finding 10% of 3,600 and multiplying the result by 2 or by finding 1/5 of 3,600.
Step-by-step explanation:
Given
[tex]Goal = 3585[/tex]
[tex]Collected = 21\%[/tex]
[tex]Kurt= 10\% * 3600 * 2[/tex]
[tex]Maria = \frac{1}{5} * 3600[/tex]
Required [Missing from the question]
Who is correct and why?
First, we calculate the actual amount collected.
[tex]Actual = Collected * Goal[/tex]
[tex]Actual = 21\% * 3585[/tex]
[tex]Actual = 752.85[/tex]
[tex]Actual = 753[/tex] --- approximate
Next, determine the estimate (round 3585 to 3600 and 21% to 20%)
[tex]Estimate = 20\% * 3600[/tex]
[tex]Estimate = 720[/tex]
Next, calculate Kurt and Maria's estimates
[tex]Kurt= 10\% * 3600 * 2[/tex]
[tex]Kurt = 720[/tex]
[tex]Maria = \frac{1}{5} * 3600[/tex]
[tex]Maria = 720[/tex]
Hence, Kurt and Maria are correct because of option (d)

PLEASE HELP Write a one chunk paragraph explaining the steps to solve for the equation 3(2x+1)=4x+5
Answer:
x = 1
Step-by-step explanation:
First perform the indicated multiplication:
3(2x+1)=4x+5 becomes 6x + 3 = 4x + 5.
Consolidate like terms: 2x = 2
Solve for x: x = 1
Answer:
Step-by-step explanation:
To solve the equation, first you would multiply 3 times 2x and 3 times 1. Then, you would write 6x plus 3 on the right side of the equation. Then, you would subtract 3 from both sides of the equation. You then will have 6x=4x+2. Lastly, you would get an answer of x=1

Step-by-step explanation:
the table shows the costs of different size jars of peanut butter. Which of the jars have the lowest unit rate?
Answer:
Step-by-step explanation:
Option C) 25-oz jar has the lowest unit rate
What is the unit rate?Unit rate is the ratio of two different units, with the denominator as 1. For example, kilometer/hour, meter/sec, miles/hour, salary/month, etc
Given here the cost of a 12 oz jar is $3
so the unit rate of a 12 oz jar is = 12/3
= 4
similarly, the unit rates of all the jars from the given table are
18 oz jar = 18/4.40
= $4.09
25 oz-jar = 25/6.75
= $3.703
32 oz jar = 32/8.25
= $3.87
Hence the jar with the lowest unit rate is the 25 oz jar
