Step-by-step explanation:
they expect originally to put 12 songs on the CD.
are you sure about the 2% ? is that not 20% ? or better 25%.
because
100% = 12
1% = 100%/100 = 12/100 = 0.12
2% = 1%×2 = 0.12×2 = 0.24
"0.24 songs more" does not really make any sense.
20% would then be 2.4 songs, which would mean 2 songs, but 2 would be only 2/0.12=16.7%.
but 25% would be 0.12×25 = 3. so, 3 songs more.
and that makes sense.
so, they produced 25% or 3 songs more than they expected to put on the CD. that is 12+3=15 songs.
now, we have a new 100% :
100% = 15
1% = 15/100 = 0.15
40% = 0.15×40 = 6
so, 6 songs are removed.
that leaves 9 songs on the CD.
In Texas, the coldest temperature ever recorded is
–
23°F. That's a lot chillier than in Florida, where the coldest recorded temperature is
–
2°F.
How many degrees warmer is Florida's coldest recorded temperature than Texas's?
°F
Answer:
I searched this and it said Florida's coldest temperature was -2°F and Texas's was -23. So the answer is 21.
Step-by-step explanation:
Texas's lowest temp: -23
Florida's lowest temp: -2

What is the slope of the line on the graph?
Answer:
6/1 or just 6
Step-by-step explanation:
Answer:
6 over 1 is the slope
Step-by-step explanation:
to find the slope of a line you have to find two points on the line and do rise over run
so for example for this problem I looked at the tho points and starting from the bottom one I went up (rise) six and over (run) one and got 6 over 1

a b and c are positive integers a:b
=3:8 and b:c=6:11
Answer:
a= 18; b= 48; c= 88. Please note that even half these value work (9, 24, 44) or any multiple of these (9k, 24k, 44k, with k a positive integer)
Step-by-step explanation:
Let's go easy, and pick b to be 6x8, to make things easy for us. Maybe even 6x4 could work, 12x8 will totally work, but this is the simplest choice.
Now on the first proportion [tex]a:48=3:8 \rightarrow 8a = 48\times3 \rightarrow a = 18[/tex]
From the second proportion [tex]48:c=6:11 \rightarrow 6c = 48\times 11 \rightarrow c = 88[/tex]
what is the slope of the line // will give lots of points and brainliest
Answer:
1/2
Step-by-step explanation:
It usually works well to compute the slope from coordinates where the graph crosses grid line intersections. We can identify two of those as ...
(-1, 3) and (1, 4)
The slope formula tells you the slope is ...
m = (y2 -y1)/(x2 -x1)
m = (4 -3)/(1 -(-1)) = 1/2
The slope of the line is 1/2.

Given the point (5, 6) and the slope of 5, find y when x = 21.
Answer:
y = 86
Step-by-step explanation:
We know the slope is 5 so we can write our equation like this:
y = 5x + b
Since we know that (5, 6) is on our equation, we can substitute it into our equation:
6 = 5(5) + b
b = 6-25 = -19
Now we know our equation is y = 5x - 19
Next, we plug in 21 for x to find our y-value:
y = 5(21)-19 = 105-19 = 86

a rental truck has a cargo capacity of 96 ft ^3 a ft pipe just fits resting diagonally on the floor of the truck if the cargo space is 8ft high, find the dimensions of the truck
The dimension of the truck is 8ft by 6t by 2ft
The volume of the rental cargo is expressed according to the formula;
V = lwh
l is the length of the box
w is the width
h is the height
Given the following parameters
V = 96ft^3
h = 8ft
Substitute into the formula
96 = 8lw
lw = 96/8
lw = 12
The other dimensions of the tuck will be 2ft and 6ft respectively
Hence the dimension of the truck is 8ft by 6t by 2ft

Graph: y–3=1/2(x+2)
Answer:
Step-by-step explanation:
Solve the y
y -3 = 1/2(x + 2)
y = 1/2(x + 2) + 3 Add
Pick points that you wish to substitute for x values.
x = 0 x = 2 x = 4
y = 1/2(x + 2) + 3 y = 1/2(x + 2) + 3 y = 1/2(x + 2) + 3
y = 1/2(0 + 2) + 3 y = 1/2(2 + 2) + 3 y = 1/2(4 + 2) + 3
y = 1/2(2) + 3 y = 1/2(4) + 3 y = 1/2(6) + 3
y = 1 + 3 y = 2 + 3 y = 3 + 3
y = 4 y = 5 y = 6

For a spherical object to just barely block the sun from your view, the ratio of the
length of the object's conical shadow, measured from the object to your eye, to
the object's diameter must be about 108: 1. How far in feet from your eye would a

The tennis ball's distance from the eye can be determined by using similar triangles.
The distance of the tennis ball from the eye to block out the Sun is; 24.3 feet.
Reasons:
The given parameter are;
The ratio of the shadow to the objects diameter = 108 : 1
[tex]\dfrac{108}{1} = \dfrac{Distance \ of \ tennis \ ball}{2.7}[/tex]
The distance of the tennis ball from the eye = 108 × 2.7 in. = 291.6 in.

Find the cost per visit to the nearest cent: Health and Heart Club, $259 per year, 3 visits per week.
$7.19
$1.66
$3.32
$156
Answer: The answer is A $1.66
Step-by-step explanation: We have been given that Health and Heart Club charges $259 per year. A person has 3 visits per week. We are asked to find the cost of per visit to Health and Heart Club.We know that there are 52 weeks in one year. So total visits in one year would be 3 times 52 that 156 visits.
Now, we will divide total cost by 156 to find cost per visit.
Cost per visit = $1.660256
Rounding to nearest hundredths, we will get: Cost per visit = $1.66
Therefore, the cost per visit is $1.66 and option 'a' is the correct choice.

Make 'y' the subject of the formula: 17t+3hy=24
Answer:
y=[tex]\frac{24-17t}{3h}[/tex]
Step-by-step explanation:
Hi there!
We are given the formula 17t+3hy=24
We want to make y the subject of the formula, which also means that we want to solve the equation for y
To do that, we'll need to isolate y on one side, much like solving for an equation with real numbers.
Let's first subtract 17t from both sides.
17t+3hy=24
-17t -17t
___________
3hy=24-17t
Now on the left, we have 3hy, but remember; we want just y by itself. Once again, similar to solving an equation with real numbers, we can pretend that 3h is the coefficient of the equation, while y is our variable.
So to get y by itself, we'll need to divide both sides by 3h
y= [tex]\frac{24-17t}{3h}[/tex], which can also be written as y=[tex]\frac{8}{h} -\frac{17t}{3h}[/tex]
