What is the percentage?Percentage is a way to express a number as a fraction of 100. It is often used to represent ratios and proportions in a more convenient and understandable form, especially in financial and statistical contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".
Given that,
After a few mathletes join the team, the team is able to solve 40% more problems per session
Let X be the number of problems the team was able to solve before the new mathletes joined.
We know that after the new mathletes joined, they were able to solve 42 problems per session, which is 40% more than before, so:
X x 1.40 = 42
Solving for X:
X = 42 / 1.40 = 30.

The side of a box has length x feet, and another side has length (x-7) feet. What value of a would produce an area of 18 square feet?
Answer:
x=9
Step-by-step explanation:
(9-7) = 2
9 times 2 = 18 square feet
Value of x is 9 , -2
Given that;
Length of box = x feet
Width of box = (x - 7) feet
Area of box = 18 square feet
Find:
Value of x
Computation:
Area of rectangle = Length × Width
Area of rectangular box = x × (x - 7)
x² - 7x = 18
x² - 7x - 18 = 0
Using factorisation;
x² - 7x - 18 = 0
x² - (9 - 2)x - 18 = 0
x² - 9x + 2x - 18 = 0
x(x - 9) + 2(x - 9) = 0
(x - 9)(x + 2) = 0
So,
x = 9, x = -2

Great freight a local shipping company charges .40 per pound for shipping if your shipping 20 pounds what would the cost be
Answer:
$8.00
Step-by-step explanation:
For every pound shipped, $0.40 is charged. This can be represented by the mathematical equation: y=0.4x, where x is the pounds to ship and y is the total cost. If we plug in 20 as x to find what the total cost would be, we would have the equation, y=0.4*20, and y would equal 8, meaning that the total cost is $8.00.

Chord AC intersects chord BD at point P in circle Z. AP=12 m DP=5 m PC=6 m What is BP?
Answer:
BP = 14.4
Step-by-step explanation:
Given 2 chords intersecting inside a circle, then
The products of the measures of the parts of one chord is equal to the product of the measures of the parts of the other chord, that is
BP × DP = AP × PC , that is
BP × 5 = 12 × 6
5BP = 72 ( divide both sides by 5 )
BP = 14.4

Thomas decides on a destination for his vacation. If he takes the train there, it will take 5 1/8 hours to get there. If he takes the plane, it will take him 2 2/3 hours
Answer: 2 11/24
Step-by-step explanation:
How many hours does the plane save?
Time taken for the train = 5 1/8
Time taken for the plane = 2 2/3
The number of hours saved will then be:
= 5 1/8 - 2 2/3
Let the lowest common multiple be 24
= 5 3/24 - 2 16/24
= 2 11/24
The number of hours saved by the plane will be 2 11/24

Answer:
Michelle is correct.
Step-by-step explanation:
The statement Michelle said is valid and correct since 10 to the power of 3 in the denominator is equivalent to 0.001 in the numerator.
Dividing by 1,000 is the same as multiplying by 0.001.
The solution to a system of linear equations is (0,4) one of linear equations in the system is y=8x+4
Answer:
(-1/2, 4)
Step-by-step explanation:
Get the x intercept. The x intercept occurs at when y = 0
0 = 8x + 4
-8x = 4
x = 4/-8
x = -1/2
Get the y intercept
y intercept occurs at x = 0
y = 8(0) + 4
y = 0+4
y = 4
Hence the required solution is (-1/2, 4)
