How do I write a percent problem for which the percent is greater than 100 and the part is known???
Percentages greater than 100% can be expressed as x% where x is any real number
How to express a percentage greater than 100%?As a general rule, percentages are represented by %
Take for instance
x% is pronounced x percentage
Where x is any real number
Whether x is greater than 100 or not, the format of the expression remains the same
i.e. 150 percent is written as 150% and 25 percent is written as 25%
Hence, percentages greater than 100% can be expressed as x% where x is any real number

Now do equation and find the value of y.
Answer:
MP = 29
mp = mn + np
17 + 3y = 5y + 9
2y = 8
y= 4, NP = 3(4) = 12

Given two terms of each arithmetic sequence, find a₁ and d .a₄=-2.4 and a₆ = 2
The common difference d is 2.2 and the first term a1 is -9.
How to find the a1 and d?The difference between any two consecutive integers in an arithmetic progression (AP) sequence of numbers is always the same value.
The formula of Arithmetic progression is
a(n) = a1 + (n - 1)d
given that the two terms of arithmetic sequence,
a4 = -2.4 and a6 = 2.
now, find the common difference d.
a(n) = a1 + (n - 1)d
Let take a(n) = a6 and a1 = a4.
a6 = a4 + (6 - 4)d
a6 = a4 + 2d
now substitute the values of a6 and a4
2 = -2.4 + 2d
2 + 2.4 = 2d
d = 4.4/2
d = 2.2
so, the common difference d is 2.2.
then, find the term a1.
take the formula
a(n) = a1 + (n - 1)d
now, substitute a(n) = a4 and d = 2.2.
-2.4 = a1 + (4-1)d
-2.4 = a1 + 3d
-2.4 = a1 + 3(2.2)
-2.4 = a1 + 6.6
a1 = -6.6-2.4
a1 = -9.
so, the first term a1 is -9.
Hence, the common difference d is 2.2 and the first term a1 is -9.

Determine the slope of the line that contains the given points.
J(7,-3), K(-8,-3)
The slope of the line containing (7,-3) and (-8,-3) is Zero(0).
The slope of a straight line can be written as follows,
m = [tex](y_{2} - y_{1} )/(x_{2} - x_{1} )[/tex] equation1
The line is containing the points (-3,3) and (4,3). So, we can write
[tex]y_{2}[/tex] = -3 , [tex]y_{1}[/tex] = -3 , [tex]x_{2}[/tex] = -8 , and [tex]x_{1}[/tex] = 7 .
On substituting the values of variables in equation1, we will get
m = ( (-3)-(-3) ) / ( (-8)-(7) ) = (0/(-15)) = 0.
As the slope of a line is Zero(0), so we can conclude that the given line is a straight line.
Here:
m = the slope of the line
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] ) are the first coordinates.
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )are the second coordinates.
The slope of the line containing (7,-3) and (-8,-3) is Zero(0).

In right AABC with mzC-90°, mzB-75°, and AB = 12 cm. Find the area
of AABC.
The area of triangle ΔABC with ∠C = 90°, ∠B = 75° an AB = 12 cm will be 18.16 square centimeters.
We have a right - angled triangle ΔABC.
We have to find the area of ΔABC.
What is Pythagoras theorem ?Pythagoras theorem states - In a right - angled triangle ΔABC, the square of the hypotenuse is equal to the sum of the squares of the base and perpendicular. Mathematically -
h² = b² + p²
According to the question -
(Refer to the image attached)
∠C = 90°
∠B = 75°
AB = 12 cm
Now -
sin 75° = AC/AB
AC = AB sin(75°) = 12 sin(75°) = 12 x 0.97 = 11.64 cm
and
tan 75° = AC/BC
BC = AC/tan(75°) = 11.64/3.73 = 3.12 cm
Therefore, the area of triangle ΔABC -
A = 1/2 (AC x BC) = 0.5 x 3.12 x 11.64 = 18.16 cm²
Hence, the area of triangle ΔABC will be 18.16 cm².

6. Fudge There are 99 calories in an ounce of cream cheese,

chocolate. Salt has 0 calories. (See Example 2.)
a. How many calories are in the fudge recipe?
b.
This recipe uses an 8-inch by 8-inch dish. How many
calories are in a 1-inch by 1-inch piece of fudge?
Using proportions, it is found that:
a. There are 2736 calories in the fudge recipe.
b. There are 42.75 calories in a 1-inch by 1-inch piece of fudge.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
For this problem, the recipe is composed by:
6 ounces of cream cheese: 99 calories per ounce.1/8 of a teaspoon of salt: 0 calories.1/2 of a teaspoon of vanilla extract: 12 calories in a teaspoon.4 cups of sugar: 389 calories per cup.4 squares of chocolate: 145 calories per square.Hence the number of calories in the recipe is given by:
6 x 99 + 0.5 x 12 + 4 x 389 + 4 x 145 = 2736.
There are 2736 calories in the fudge recipe.
For item b, the areas are given as follows:
Dish: 8 x 8 = 64 inches².Piece: 1 x 1 = 1 inch².Hence the piece of fugde is 1/64 of the recipe, thus:
1/64 x 2736 = 42.75 calories.

i) cost of oil change = $29.99
ii) Balance on December 1 = $252.009
iii) Difference between the two balance = $85.79
According to the question we have been that
Total balance on November 1 = $337.88
i) We need to find how much did the oil change cost.
For that we will first calculate how much balance was left after depositing after pay check.
Balance after spending in groceries= $337.88 - $ 42.59 = $295.29
Balance after depositing from savings account = $295.29 + $125.00 = $420.29
Balance after spending in electric bill = $420.29 - $35.67 = $384.62
Balance after depositing from paycheck = $415.00 + $384.62 = $799.62
Therefore, Cost of oil changing = $799.62 - $769.63 = $29.99
ii) For the balance on December 1 after rent had paid, we will first calculate the balance after spending for birthday present.
Balance after spending for birthday present = $769.63 - $17.54 = $752.09
Therefore the balance on December 1 = $752.09 - $500.00 = $252.09
iii) Difference in the two balance is
= balance on November 1 - Balance on December 1
= $337.88 - $252.09
= $85.79
Hence the difference in the two balances is $85.79

A list of Marc's running times, in seconds, for his first 4 races is shown.
23.1, 23.2. 22.8, 21.9
What is the maximum running time, in seconds, Marc can have in his last race in order to qualify for the championship? Round the answer to
the nearest tenth.
______ seconds
the maximum time that he can have in his last race is 23 seconds.
What is the maximum running time, in seconds?
We know that the average can not be greater than 22.8 seconds, then if x represents the time of the last race, the maximum value that x can take is given by the equation:
(23.1 + 23.2 + 22.8 + 21.9 + x)/5 = 22.8
(That is the equation for the mean of the 5 times)
Solving that for x we will get:
(23.1 + 23.2 + 22.8 + 21.9 + x) = 5*22.8
91 + x = 114
x = 114 - 91 = 23
So the maximum time that he can have in his last race is 23 seconds.

If the value of m = -6 and b = 9 then 6x + y = 9 be the standard form.
What is meant by slope intercept form?Y = mx + b is the general formula for the slope-intercept form, where m stands for the line's slope and b for the y-value of the line's y-intercept. We may more easily determine a line's slope and its y-axis intersection using the slope-intercept form of a linear equation.
Let the value of m = -6(slope)
b = 9 (y -intercept)
The slope-intercept form is given by,
y = mx + b
y = -6x + 9
Therefore, y = -6x + 9 is the slope-intercept form
Standard form is given by, Ax + By = C
Since, slope-intercept form is y = -6x + 9

The size of the segment in the scale drawing using a drawing scale factor of 5 meters to one box is 30 meters.
What are scale factors?A scale factor is a value with which the dimensions of an original two dimensional geometric figure or a three dimensional solid can be multiplied to obtain an image.
Scale factors are used in maps and drawings to represent a large geographic area, or a life sized object on paper, such that the relative sizes of the sides of the original figure are maintained
Solution;
Using the height of the arc in the drawing as the reference, we have;
50 m is equivalent to 10 boxes
Therefore;
The length of one box = (50 m)/10 = 5 m
The scale of the drawing is therefore;
One box = 5 metersThe length of the given segment = 6 box length
