Penny, Amjit and James share some money in the ratio 3 : 6 : 4
Amjit gets $28 more than James.
Work out the amount of money that Penny gets.
Answers
Answer:
$42
Step-by-step explanation:
Let the amounts received by Penny, Amjit and James be 3x, 6x and 4x respectively.
According to the given information:
Amount received by Amjit = Amount received by James + 28
So,
6x = 4x + 28
6x - 4x = 28
2x = 28
x = 28/2
x = 14
Amount of money received by Penny = 3x = 3*14 = $42
The radius of a circle can be approximated using the expression √(A/3). A circular kiddie swimming pool has an area about 28 square feet. An inflatable full-sized circular pool has an area of about 113 square feet. How much greater is the radius of the full-sized pool than the radius of the kiddie pool? round to the nearest whole number.
It says Hint: First find the radius of each pool by substituting for A in the expression. Divide by 3 before approximating square root.
Answers
Answer:
yeah I know you are literally perfect for you to be home
By using the expression to approximate the radius of a circle, we want to compare the radius of the two pools. We will find that the radius of the full-sized pool is 2 times larger than the radius of the kiddie pool.
The expression for the radius of a circle is:
R = √(A/3)
Where A is the area of said circle.
The circular kiddie swimming pool has an area of 28ft^2, we just replace that in the above expression to get:
R = √(28 ft^2/3) = 3 ft
The full-sized pool has an area of 113 ft^2, then its radius is:
R' = √(113 ft^2/3) = 6 ft
To see how much greater is the radius of the full-sized pool than the radius of the kiddie pool, we just take the quotient:
R'/R = 6ft/3ft = 2
Meaning that the radius of the full-sized pool is 2 times larger than the radius of the kiddie pool.

Sadie had 55 stickers. Each day she gave away 5 stickers to her friends.
Write an equation to model this situation in the form y = mx + b, but do not
include any spaces in your answers. (for example y=6x+1)
Answers
Answer:
55 = 5x
Step-by-step explanation:
Sadie had 55 stickers. Each day she gave away 5 stickers to her friends.
Write an equation to model this situation in the form y = mx + b, but do not
include any spaces in your answers. (for example y=6x+1)
Equation to model this situation in the form y = mx + b,
y = Total number of stickers she had
x = Number of days that she gave away sticker
b = Fixed value = 0
Hence:
55 = 5x + b
b = Fixed value = 0
Therefore, the situation is represented as:
55 = 5x

The question is incomplete, the complete question is;
two fractions have the same numerator, but different denominators. is the fraction with the greater denominator greater than or less than the fraction with the lesser denominator
Answer:
The fraction with the greater denominator is less than the fraction with the lesser denominator
Step-by-step explanation:
A fraction refers to a ratio of two number. A fraction has a numerator (The number on top) and a denominator (The number below).
If i have two fractions having the same numerator, then, the fraction with the greater denominator is less than the fraction with the lesser denominator.
Let me give you an instance, if i have 2/3 and 2/5.
We know that 5 > 3 hence 2/5 < 2/3

Answer:
b^3 + c^2
Step-by-step explanation:
b^3 * c^2
Explanation:
Here we see that there are 3 B’s being multiplied against each other. This can be written as b^3, because b^3 also represents b*b*b.
Next, there are two c’s being multiplied against each other. This can be written as c^2, because c^2 also represents c*c.
Now that we have found what the exponents are we can multiple both b^3 and c^2 to get our final answer of:
b^3 * c^2

The number of cell phones that employees at a factory can assemble is directly proportional to the number of hours the employees spend assembling cell phones. The employees can assemble 1,576 cell phones in 8 hours. If these employees continue to work at the same rate, how many cell phones will they assemble in 53 hours?
Answers
Answer:
10,441
Step-by-step explanation:
The number of cell phones the employees can assemble in 53 hours will be 10441.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
For example the speed 3meter/second.
As per the given,
1,576 cell phones in 8 hours.
Number of cell phones sells per hour or rate of change,
1576/8 = 197 cell phones/hour.
The number of cell phones sells in 53 hours,
197 cell phones/hour x 53 = 10441 cells phones.
Hence "The number of cell phones the employees can assemble in 53 hours will be 10441".

The values of x and y in the following equation system are 20 and 110, respectively.
What are System of equation?simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods to solving systems of equations: graphing, substitution, elimination and matrices.
given a system of equation:
30x + 4y = 1,040.....(1)
12x + 16y = 2,000...…(2)
We will solve it by using substitution method,
Multiply with 2.5 in equation (2) and subtract it from equation (1)
30x + 4y - 30x - 40y = 1040 - 5000
36y = 3960
y = 110
Substitute this value of y in equation (1)
30x + 440 = 1040
30x = 600
x = 20
Therefore, The value of x and y are 20 and 110 respectively for the given system of equation.

(a)
(b) Make V the subject of the formula T = 4v + 3
Answers
(T - 3) / 4 = v
The equation T = 4v + 3 is solved for v will be written as v = (T - 3) / 4.
What is the solution to the equation?The possible value of the variables that satisfy the equation which is known as the solution of the equation.
The equation is written below.
T = 4v + 3
The degree of the equation is one. Then the equation is given a linear equation.
Solve the equation for v, then we have
T = 4v + 3
Subtract 3 from both sides, then we have
T - 3 = 4v
Divide the equation by 4 into both sides, then we have
v = (T - 3) / 4
The equation T = 4v + 3 is solved for v will be written as v = (T - 3) / 4.
