Answer:
3/25
Step-by-step explanation:
probability of getting 1 cream filled and 1 jelly donut = (Total number of cream filled donut / total number of donuts) x (Total number of jelly filled donut / total number of donuts)
total number of donuts = 3 + 3 + 4 = 10
(3/10) x (4/10) = 12/100
to express in is simplest term, divide through by 4 = 3/25

Answer:
n= 1/2 m−x
Step-by-step explanation:
m=2(x+n)
Step 1: Flip the equation.
2n+2x=m
Step 2: Add -2x to both sides.
2n+2x+−2x=m+−2x
2n=m−2x
Step 3: Divide both sides by 2.
2n/2 = m−2x /2
n= 1/2 m−x

then
3/2x = 5+1
then
3/2x = 6
then
x = 6 / (3/2)
then
x = 6 *2/3

Question 1:
A trader made a profit of 20% on a radio which he sold for N144 .Calculate the cost price of the radio .
Question 2:
A motor dealer sold a car at a loss of 20% by selling it at N10,000 . Find the cost price.
Note :
Cost price formula :
[tex]C.P = S.P-P \\ or S.P+L[/tex]
Selling Price Formula :
[tex]S.P = C.P + P \\ or C.P - Loss[/tex]
Profit Percentage ( P% ) formula :
[tex] P \% = P/C.P × 100 \\ l \% = l/C.P × 100[/tex]
Answer:
Question 1
Given
SP = 144P = 20%CP = xUse formula and solve for x:
SP = CP + P144 = x + (20% of x)144 = x + 0.2x144 = 1.2xx = 144/1.2x = 120Cost price is N 120
Question 2
Given
SP = 1000P = -20% (negative because of loss)CP = xUse formula and solve for x:
SP = CP + P10000 = x - (20% of x)10000 = x - 0.2x10000 = 0.8xx = 10000/0.8x = 12500Cost is N 12500

What are the numbers with a sum of 9 and product of -10
Answer:
-1 , 10 and 10 , -1
Step-by-step explanation:
hello :
if x , y this numbers you have the system : x+y =9.....(*)
xy = -10.....(**)
use (*) : y = 9 - x
put this value of y in (**) : x(9-x) = -10
9x - x² = - 10
x²-9x - 10 = 0
(x+1)(x-10)=0 means : x+1 = 0 or x -10 = 0
x = - 1 or x=10
if : x= -1 y = 9-(-1)=10
if : x= 10 y = 9-(10)=1
It takes Bobby 12 hours longer to build a robot than it takes Alex. Together, they can build the Robot in 8 hours. How long does it take Bobby to build the robot by himself?
Answer:
24 hours
Step-by-step explanation:
The computation of the number of hours taken by Bobby to build the robot by himself is shown below:
Given that
Bobby could take 12 hours
Together they could build in 8 hours
So based on the above information
the number of hours taken by Bobby to build the robot by himself is
Let us assume the above line be x
So,
[tex]\frac{1}{8}-\frac{1}{12} = \frac{1}{x} \\\\\frac{6 - 4}{48} = \frac{1}{x} \\\\\frac{2}{48} = \frac{1}{x} \\\\x = \frac{48}{2}[/tex]
x = 24 hours

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that hot chocolate recipe calls for three teaspoons of cocoa for every cup of milk.
We need to find multiply 3 teaspoons by 3 cups to find the answer.
Therefore, we will use unitary method;
3 teaspoons x 3 cups = 9

What is the area of this shape?
Answer:
12mm (triangle)
165mm (whole shape)
Step-by-step explanation:
The triangle is 6 x 4 = 24 ÷ 2= 12
(divide by 2 because its a teiangle)
2nd shape is 10 x 8 = 80
3rd shape is 6 x 12 = 72
72 + 80 + 12 = 165mm
The length of a swimming pool is 22 ft. The width is 40 ft. If the volume of the pool is 2,500 m3, what equation shows you how you can find the depth of the pool?
Answer:
volume= length x width x height
Step-by-step explanation:
In this instance the height will represent the depth of the pool.
To actually solve it it would look like
2500=(22)(40)(h)
2500=880(h)
2.84=h (or depth)
The locker combination consists of 4, single digits ranging 0-9. How many possible combinations are there?
Answer:
10000 possible combinations
Step-by-step explanation:
Number of digits = 4
Range of values of each digit = 0 - 9
Number of digits in range = 10
Hence, each digit could be = (1 - 10)
1st digit = 10
2nd digit = 10
3rd digit = 10
4th digit = 10
Total possible combination :
10 * 10 * 10 * 10 = 10000 possible combinations
7b-2/5 = 6b-7/5
Solve for b.
Answer:
b = -1
Step-by-step explanation:
here's your solution
=> 7b - 2/5 = 6b - 7/5
=> 7b - 6b = -7/5 + 2/5
=> b = (-7+2)/5
=> b = -5/5
= b = -1
hope it helps
Answer:
b = -1
Step-by-step explanation: I put all the like terms together by moving 6b and -2/5, which then changed their signs to negative and positive, respectively.
7b-2/5 = 6b-7/5
7b-6b = 2/5-7/5
b = -1

Lee buys a computer and a printer for $2,028 The printer costs 30% the price of the computer. What is the price of the computer?
Answer: $1,560
Step-by-step explanation:
Assume the computer's price is x.
This means that expressing the printer in terms of x would be:
= 30% * x
= 0.3x
These two put together represent the cost of $2,028
Expression is:
x + 0.3x = 2,028
1.3x = 2,028
x = 2,028/ 1.3
x = $1,560
Computer was $1,560
Printer was therefore:
= 1,560 * 30%
= $468
