Four individuals put their money together to start a new venture. They agree to split the profits equally. N invests $1,000, X invests $2,000, Y invests $3,000 and Z invests $4,000. If the profits for the first month were $2,000, Z receives __?__ less than if the profits were divided in proportion to how much they invested.
Answer: $800
Step-by-step explanation:
N invests $1,000, X invests $2,000, Y invests $3,000 and Z invests $4,000. This in the ratio of 1:2:3:4.
If the profits for the first month were $2,000, the amount received by Z will be:
= 4/(1+2+3+4) × $2000
= 4/10 × $2000
= 4 × $200
= $800
Mr Todd buys 7 drinks at 48p each and 8 drinks at 52p each. What is the total cost of the 15 drinks?
Answer:
80p
if you are adding 4p every time you add a drink you will be adding 7 drinks therefore you have to do (7x4p) this will equal 28p then you have to add 28p to 52p

WRITE AN EQUATION which describes the line that contains (9,4) and has an undefined slope.
Answer:
x = 9
Step-by-step explanation:
A line with an undefined slope will be a vertical line.
This means the equation of the line will be in x = form, because the line will only go through one x value.
Since the given point has the x value of 9, this means the line will only go through that value.
So, the equation of the line will be x = 9
Can you Help me please lol
Answer:
Slope is 4/5
Step-by-step explanation:
The two points are (3,3) and (-2,-1)
The slope formula is Y2-y1 / x2-x1
So substituting in
-1-3/ -2 -3
-4/-5 = 4/5

Joe has $173 in the bank. He earns the same amount of money each week for 7 weeks and puts this money in the bank. Now joe has $208 in the bank. How much money does joe earn each week
Given:
Joe has $173 in the bank.
He puts 7 weeks earning in the banks.
Now joe has $208 in the bank.
To find:
How much money does joe earn each week?
Solution:
Let x be the same amount of money each week for 7 weeks and puts this money in the bank.
Total earning in 7 weeks = 7x
Total amount of money in bank = Initial amount + 7 Weeks earning
[tex]208=173+7x[/tex]
[tex]208-173=7x[/tex]
[tex]35=7x[/tex]
Divide both sides by 7.
[tex]\dfrac{35}{7}=x[/tex]
[tex]5=x[/tex]
Therefore, joe earns $4 each week.

Solve the rational equation 2x^2 + 1/x-1 + x = 3 + 3/x -1 A. X= 1/3, x= 1 B. X=1/3 C. X=1 D. There is no solution
Answer:
There is no solution
Step-by-step explanation:
Given the rational equation 2x^2 + 1/x-1 + x = 3 + 3/x -1
We are to find the value of x
Collect like terms
2x²+x-3 = 3/x-1 - 1/x-1
2x²+x-3 = 2/x-1
Cross multiply
(2x²+x-3) (x-1) = 2
2x³-2x²+x²-x-3x+3-2 = 0
2x³-x²-4x+1 = 0
Since we cannot factor the polynomial, hence there is no solution

what is the answer 1/2(4t + 6) = 25
Answer:
( 11 2 + y ) ( 11 2 + y ) = 8
Step-by-step explanation:
Answer:
t=11
Step-by-step explanation:
Step 1: Simplify both sides of the equation
1/2(4t+6)=25
(1/2)(4t)+(1/2)(6)=25
2t+3=25
Step 2: Subtract 3 from both sides
2t+3−3=25−3
2t=22
Step 3: Divide both sides by 2
2t/2 = 22/2
22 divided by 2 is 11

Masha biked 20km 20 minutes faster than Dasha biked 20km. Find the speed of each cyclist if one biked 2km/h faster than the other.
Answer:
12 km/h and 10 km/hStep-by-step explanation:
Let the speed of Masha = s, speed of Dasha = d
Distance = 20 kmTime difference = 20 min = 1/3 hrSpeed difference = 2 km/hAs per above info we get following equations:
s = d + 220/s + 1/3 = 20/dSubstitute s and solve for d:
20/(d + 2) + 1/3 = 20/dGet rid of fraction by multiplying all terms by 3d(d + 2):
60d + d(d + 2) = 60(d + 2)60d + d² + 2d = 60d + 120d² + 2d = 120d² + 2d + 1 = 121(d + 1)² = 11²d + 1 = 11d = 10Find s:
s = 10 + 2 = 12The answer is
Masha's speed 12 km/h and Dasha's speed 10 km/hThe graph of a sinusoidal function intersects its midline at (0,-2) and then had a minimum Point at (3pi/2,-7)

It costs Johnny $15 a month plus $1.50 per song to download music. This situation is represented by the expression 1.5x + 15, where x is the number of songs downloaded. How much will it cost Johnny to download 10 songs?
please hurry I need to pass math
Answer:
$30
Step-by-step explanation:
To find the cost, plug in 10 for x, then simplify
1.5x + 15
1.5(10) + 15
= 30
So, it will cost Johnny $30 to download 10 songs
The total amount of money that Johnny will have to pay is f(10) = 30.
What are expressions?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators
Given is that it costs Johnny $15 a month plus $1.50 per song to download music. This situation is represented by the expression →
1.5(x) + 15.
The expression is given by -
f(x) = 1.5(x) + 15
where [x] is the number of songs downloaded.
For [x] = 10 songs, the total amount of money that Johnny will have to pay is -
f(10) = 1.5 x 10 + 15
f(10) = 15 + 15
f(10) = 30
Therefore, the total amount of money that Johnny will have to pay is f(10) = 30.

Rewrite the equation so that it does not have fractions 2- 5/6x = 7/8
the common denominator of 5/6 and 7/8 is 24, so multiply both sides of the equation (every term) by 24:
24(5/6)x + 24(2) = 24(7/8)
the denominators will cancel out so you have:
4(5x) + 48 = 3(7)
do the multiplication:
20x + 48 = 21
fractions have been eliminated, and if you want to continue to solve:
20x = -27
x = -27/20

Answer:
y=1/2 +1.5
Step-by-step explanation:
y intercept = 1.5
gradient = rise over run = 1/2
y = 1/2 +1.5
Answer:
[tex]y=\frac{1}{2}x+\frac{3}{2}[/tex]
Step-by-step explanation:
Slope-intercept form: [tex]y=mx+b[/tex] when [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the y-coordinate of the point where the line crosses the y-axis)
1) Find the slope ([tex]m[/tex])
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] when the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
We can use any two points on the line to plug into this equation, but it's often easiest to use points that have whole-number coordinates. For example, we can use the points (1,-1) and (3,0).
[tex]m=\frac{0-(-1)}{3-1}[/tex]
Two negatives make a positive
[tex]m=\frac{0+1}{3-1}\\m=\frac{1}{2}[/tex]
So far, our equation looks like this:
[tex]y=\frac{1}{2}x+b[/tex]
2) Find the y-intercept ([tex]b[/tex])
We're told to approximate the y-intercept based on what appears to be true in the graph. In the graph, we can see that the y-intercept appears to occur when y=-1.5, or when y=[tex]-\frac{3}{2}[/tex]. Therefore, [tex]b=\frac{-3}{2}[/tex].
Now, after plugging both [tex]m[/tex] and [tex]b[/tex] into our equation, our final equation looks like this:
[tex]y=\frac{1}{2}x+\frac{3}{2}[/tex]
