The lengths of the three sides are 14 feet, 19 feet and 23 feet respectively.
How to determine the length of the sidesThe formula for determining the perimeter of a triangle is expressed as;
Perimeter = a + b + c
Where; a, b and c are the length of the sides
From the information given, we have that;
y = 5 + zx = 2z - 5Perimeter = 5656 = 2z- 5 + 5 + z + z
collect like terms
56 = 4z
Make 'z' the subject of formula
z = 56/4
z = 14
Shortest side, z = 14 feet
Second side, y = 5 + z = 19 feet
Third side, x = 2z - 5 = 2(14) - 5 = 23 feet
Hence, the values are 14 feet, 19 feet and 23 feet respectively.

Ingredients to make 8 pancakes
250 ml milk
1 egg
140 g flour
5 g butter
a) Work out how much milk he needs.
Using proportions, James need 750ml for 24 pancakes
ProportionProportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.
To find the amount of milk James need, we need to use proportions.
8 pancakes = 250ml milk
24 pancakes = x
cross multiply both side and make x the subject of formula
8 × x = 24 × 250
8x = 6000
Divide both sides by coefficient of x

a certain test is worth 135 points. how many points (rounded to the nearest point) are needed to obtain a score of 85%?
To obtain a score of 85% on a test worth 135 points, one needs to get 115 points. By using proportions, we get the required value.
How to write proportions?A proportion is defined as an equality between two ratios.
Consider two ratios a:b and c:d. Then, the proportion we can write,
a: b = c : d
Then, the simplification we have for this proportion is
a/b = c/d or ad = bc
Calculation:It is given that, a certain test is worth 135 points.
One to get 85% on this test, he/she needs to get X number of points.
So, we can write the proportions as
X : 135 = 85 : 100
⇒ X/135 = 85/100
⇒ X = 85/100 × 135
∴ X = 114.75 ≅ 115 points

The density of a pumpkin with a mass of 2.0 kg and a volume of 0.0060m³ is 0.003 kg / m³.
What is the density?Density of the matter means space taken by matter.
To find the density, density = mass of matter / volume of mass.
Given that mass of the pumpkin 2.0 kg and a volume of 0.0060 m³.
Now the density from the formula;
Density = mass of pumpkin / volume of pumpkin
Density = 2.0 / 0.0060
Multiply by 10000,
Density = 20000 / 60
Density = 2000 / 6
Density = 1000 / 3
Density = 0.003 kg / m³

Ira ran out of time while taking a multiple-choice test and plans to guess on the last 666 questions. Each question has 444 possible choices, one of which is correct. Let x=x=x, equals the number of answers ira correctly guesses in the last 666 questions. What is the probability that he answers fewer than 222 questions correctly in the last 666 questions?.
It is possible to calculate the probability that in the last 6 questions, there were fewer than 2 right answers, which is 53.392%.
What is Probability?The ratio of good outcomes to all possible outcomes of an event is known as the probability. The number of positive results for an experiment with 'n' outcomes can be represented by the symbol x.
The probability of an event can be calculated using the following formula.
Probability(Event) = Positive Results/Total Results = x/n
In order to better grasp probability, let's look at a straightforward application.
Let's say we need to forecast if it will rain or not. Either "Yes" or "No" is the appropriate response to this query.
There is a chance that it will rain or not. Here, probability can be used. Using probability, one may forecast the results of a coin toss, a roll of the dice, or a card draw.
According to our question-
The likelihood that responses to fewer than two of the final six questions were right can be calculated using the procedure below:
There are 6 questions with a total of 4 possible answers, hence the value of p is:
The following formula provides the probability:
The following formula is used to calculate the likelihood that Ira would properly answer exactly 1 of the final 6 questions:
P(X = 1) = 0.35595
P(X = 0) = 0.17797 gives the likelihood that Ira will correctly answer 0 out of the final 6 questions.
Accordingly, the likelihood that the last 6 questions' answers contain fewer than 2 valid responses is: P = 0.17797 + 0.35595.
P = 0.53392
P = 53.392%
Hence, the probability that in the last 6 questions, there were fewer than 2 right answers, which is 53.392%.

A toy jeep i 12 and 1/2 inche long while an actual jeep meaure 18 3/ 4 feet long what i the value of the ratio length of the toy jeep to the length of the actual Jeep what doe thi ratio mean in the ituation?
Therefore the solution of this question is ratio length = every 1 inch of toy car represents 1.5 feet of actual car
What is ratio?In mathematics, a ratio shows how two numbers are multiplied together. In a bowl of fruit, for instance, the proportion of oranges to lemons is eight to six if there are eight oranges and six lemons. Lemons to oranges are divided 6:8 and oranges to all other fruits are divided 8:14 in a similar fashion.
Here,
A toy Jeep measures 12 1/2 inches.
Before calculating the ratio, let's first convert each size into the same unit of measure and decimal points:
=>12 ½ = 25/2
=> 12.5 inches;
=> 18 ¾ = 75/4
=> 18.75 feet .
The actual length of a jeep is 18.75 feet.
The ratio can now be determined by converting feet to inches.
1 inch of a toy car equals 1.5 feet of an actual car because
=> 1 foot = 12 inches
=> 12.5 inches : 225 inches
=> 225 / 12.5
=> 18 inches
Therefore, every 1 inch of toy car represents 1.5 feet of actual car.

and y+2 =1/6(x-4)
The equation of line in slope-intercept form is,
a.) y = -6x - 47
b.) y = x/6 - 8/3
What is Equation of line ?
A straight line's general equation is y = mx + b, where m denotes the gradient and y = b denotes the point at which the line crosses the y-axis. On the y-axis, this value b is referred to as the intercept.
We know, slope-intercept form is
y = mx + b
The given equation is in point slope form,
a.) y + 5 = -6 (x + 7)
b.) y + 2 = 1/6 (x-4)
Now, let's write each equation in slope-intercept form,
a.) y + 5 = -6 (x + 7)
y + 5 = -6x - 42
y = -6x - 42 - 5
y = -6x - 47 [which is slope-intercept form]
b.) y + 2 = 1/6 (x-4)
y + 2 = 1/6 * x - 1/6 * 4
y + 2 = x/6 - 2/3
y = x/6 - 2/3 - 2
y = x/6 - [2/3 + 2]
y = x/6 - [(2 + 6) / 3 ]
y = x/6 - 8/3 [which is slope-intercept form]
Hence, the equation of line in slope-intercept form is y = -6x - 47 and y = x/6 - 8/3

You receive paychecks every two weeks. Your first paycheck is for $217. The second is for $258. The third is for $229. What is the combined value of these three paychecks?
Answer:
The combined value is $704

The problem asks for the combined value of the three paychecks. So all you have to do is add them to get 704.
I found the average value by adding them to 704 then dividing it by 3. The 3 came from the amount of values we have which is 3 paychecks. So we divide the total cost by 3 to get 235.
