find the number of calories in a stalk of celery and in a carrot, a carrot hs 13 calories more then a celerystalk, five carrots and 1o celery stalks have only 170 calories
The number of calories in stalk of celerystalk and carrot is found as 20 and 7 respectively.
What is defined as the method of substitution?The algebraic method for solving simultaneous linear equations is the substitution method. The value with one variable through one equation is replaced in the other equation, as the name implies.For the given question;
Let the number of calories present in carrot is 'x'.
Let the number of calorie present in celerystalk is 'y'.
Carrot has 13 more calories than celerystalk.
Thus,
x = y + 13 ......eq 1
Now, 5 carrots and 10 celery stalks have total 170 calories.
The equation becomes.
5x + 10y = 170
Substitute the value of x from eq 1.
5(y + 13) + 10y = 170
Simplify the equation;
5y + 65 + 10y = 170
15y = 105
y = 7 (number of calories in stalk of celerystalk)
Put the value of y in eq 1.
x = y + 13
x = 7 + 13
x = 20 (number of calories in stalk of carrot)
Thus, the number of calories in stalk of celerystalk and carrot is found as 20 and 7 respectively.

In a particular college class, 60% of the students are female. Of the female students, 75% have long hair. One student is picked randomly in the class. What is the probability that it is a female with long.
There is a 0.75 percent chance that the person is a woman with long hair.
What is probability?Probability can be used to define potential. The occurrence of a random event is the focus of this mathematical field. There is a 0 to 1 value range. The likelihood of anything happening is often referred to as probability. Utilize probability to gauge a situation's likelihood of happening. Numerous factors are difficult to forecast with absolute precision. Using it, we can only speculate on whether or how likely it is that an event will occur. A probability scale with a value of 0 for an impossibility and 1 for a certainty. In a sample space, there is a one probability for every event.
E is the probability of an event . Hence,
P(E) is the ratio of favorable results to all outcomes.
In probability, an event is deemed dependent if it is impacted by other occurrences, and independent if it is wholly unaffected by the occurrence of any other event.
By applying the literature and formulas previously mentioned, we have:
F should signify for the fact that the student is female, and L should stand for the fact that the student has long hair.
P(F)
= 0.60
P(L)
= 0.50
P(F AND L)
= 0.45
P(L|F)
= 0.75
There is a probability of 0.75 that a randomly chosen student has long hair.

144 is the largest angle in supplementary angle .
What is an example of a supplementary angle?
Angles that add up to 180 degrees are referred to as supplementary angles. For instance, the sum of angle 130° and angle 50° is 180°, hence they are supplementary angles.The pair of angles known as supplementary angles always add up to 180 degrees. The terms "supplements" for these two viewpoints describe them. The Latin terms "Supplere" and "Plere," which mean "supply" and "fill," respectively, are the source of the English word "supplementary."Let one angle = x
then other angle is four times the other = 4x
x + 4x = 180
5x = 180
x = 180/5
x = 36

What is volume?Volume is a measurement of three-dimensional space that is occupied. It is frequently expressed mathematically using imperial or SI-derived units. Volume and the notion of length are connected.
Given Data
At t=0, Water Volume is 3,000 Litres
The volume of water in the tank equals t hours later.
As it is also stated, there is x% less water in the tank at the conclusion of every hour than there was at the beginning.
After an hour, the amount of water is equal to 3,000 - = 3,000 - 30 x
Water consumption after two hours = (3,000 - 30 x) - (3,000 - 30 x)
×= (3,000 - 30 x) (3,000 - 30 x)
Also,
= 288120
⇒300000 - 3000 x - 3000 x + 30 x²
= 288120
⇒ 30 x ² - 6,000 x + 11880= 0
When we multiply both sides by 30, we get
⇒ x² - 200 x + 396=0
reducing the quadratic equation to factors
(x -198)(x-2) = 0
x = 198,
x = 2

Find the perimeter of this semi-circle with diameter, d = 23cm. Give your answer rounded to 1 DP.
The perimeter of the semi-circle is 59.1 cm
In this question, we have been given the diameter if the semi-circle
d = 23 cm
We need to find the perimeter of the semi-circle.
We know that, the perimeter of the semi-circle of radius 'r' is P = πr + 2r
For diameter d = 23 cm, the radius would be,
r = 11.5 cm
So, the perimeter would be,
P = πr + 2r
P = π × 11.5 + 2 × 11.5
P = (π + 2) × 11.5
P = 59.13 cm

The step 3y = 80v + x is incorrect, as 3y = 80v - x is the correct step by subtraction property of equality.
In this question, we have been given Taylor is solving a literal equation (x + 3y) / 2 = 40v
We have been given her steps that she used to solve for y.
We need to find an error in the steps.
First we solve given literal equation for y.
(x + 3y) / 2 = 40v
x + 3y = 40v × 2 .................(Multiply both the sides by 2)
x + 3y = 80v
x + 3y - x = 80v - x ...................(Subtract x from both the sides)
3y = 80v - x
y = (80v - x)/3 ............(Divide each side by 3)
If we observe Taylor's steps, we can see that there's an error in the step 3y = 80v + x.
Therefore, the step 3y = 80v + x is incorrect, as 3y = 80v - x is the correct step by subtraction property of equality.
