Answer:
x = √324 = 18
Step-by-step explanation:
x shows up only in the second problem, so I'll focus on that problem.
This is a right triangle because one of the three angles is 90 degrees.
Thus, the Pythagorean Theorem applies: x^2 + 24^2 = 30^2, or
x^2 = 900 - 576 = 324
Then x = √324 = 18

How many 4-digit numbers can you write if you can use only digits 1 and 2?
Answers
Answer:
Step-by-step explanation:
Thus if you are not allowed to repeat a digit the number of possible 4 digit numbers you can construct from 1,2,3,4 is 4 3 2 1 = 24.
The number of 4-digit numbers can you write if you can use only digits 1 and 2 is 16.
Given that, using only digits 1 and 2 form 4-digit numbers.
What is digit formation?Digits are the single symbols used to represent numbers in Maths. For example, in number 89, 8 and 9 are two digits. Hence, the numerals such as 0, 1, 2, 3,4, 5,6,7,8,9, and 0 are the form of digits which are used to represent a combination of numbers and do arithmetic operations in our day to day life.
Here,
For the first digit you are picking from 2 digits.
For the second digit you are picking from 2 digits.
For the third digit you are picking from 2 digits.
For the fourth digit you are picking from 2 digits.
2×2×2×2=16
4-digit numbers
1111, 2111, 1211, 1121, 1112, 1221, 2112, 1122, 2211, 1212, 2121, 2221, 1222, 2122, 2212 and 2222.
Therefore, the number of 4-digit numbers can you write if you can use only digits 1 and 2 is 16.

By selling an article for $320, the profit was 20% of the cost price. What was the cost price of the article?
Answers
Answer:
70 percent
Step-by-step explanation:
Lets assume initial cost price (CP) which is 100.
The profit (P) is 320 (320% of 100 is 320) understood?
Selling Price (SP) is CP +P. So SP must be 420
so basically Now CP increases by 25%. So new cost price (CP1) is 125.
SP remains constant at 420
New profit (P1) is SP - CP1 = 295
P1 as a percentage of SP is (295/420) x 100 = 70%

5. Among 70 students , 40 like tea 24 like coffee and 12 like both drinks then find
a. how many like only coffee?
b. how many like neither of the drinks?
Answers
Answer:
12 students like only coffee
12 students like neither of the drinks
Step-by-step explanation:
There are 70 students in total. 40 of them line tea, 24 of them like coffee, and 12 of them like both drinks.
Let's go reasoning step by step.
a.We have 24 students who like coffee, and we know 12 of them also like tea. The number of students who like only coffee is the difference between those numbers: 24 - 12 =12
12 students like only coffee
b.With similar reasoning as for part a, 40 students like tea, 12 of which also like coffee, then 40 - 12 = 28 students like only tea.
We have a total of 12 students who like only coffee, 28 students who like only tea, and 12 students who like both. In total there are 12 + 28 + 12 = 52 students who like any or both drinks.
Since there are 70 students in all, we can say 70 - 58 = 12 students don't like coffee nor tea.
12 students like neither of the drinks
Jacob wants to buy shirts online. Each shirt costs 200 pesos. The
shipping cost is 120 pesos. Write the linear equation representing the
following:
1. Total cost that Jacob will pay after ordering the shirt in slope-
intercept form?
2. Total cost that Jacob will pay after ordering the shirt in standard
form?
Answers
Answer:
1) y = 200x + 120
2) - 200x + y = 120
Step-by-step explanation:
Equation of the line
The equation of the line in standard form is:
Ax + By = C
Where A, B, and C are constants.
The equation of the line in slope-intercept form is:
y = mx + b
Being m the slope and b the y-intercept.
1)
Each shirt costs 200 pesos. Let's assume Jacob purchases x shirts. The cost of the shirts alone is 200x.
Assuming the shipping cost is 120 regardless of the purchased shirts, then the total cost is:
y = 200x + 120
This is the slope-intercept form of the line.
2) Rearranging the above equation:
- 200x + y = 120
It's the standard form of the line

Answers

Answer:
see below
Step-by-step explanation:
Starting from the point-slope equation ...
y -y1 = m(x -x1)
Solving for y gives ...
y = mx +(y1 -m·x1)
So, the slope-intercept form equation is fairly easily found:
y = mx +b . . . . where m = m, and b = y1-m·x1
This is the equation we have used for 'b' in the attached spreadsheet.
__
Of course, the formula for slope is ...
m = (y2 -y1)/(x2 -x1)
This is the equation we have used for 'm' in the attached spreadsheet. For all problems, we have used the first point. (It doesn't matter which point you use if there are two of them.)
__
The second attachment is the Google Sheets spreadsheet saved in ODS format. Most spreadsheet programs should be able to open that so you can see the formulas, if you're interested. (The gray values of m are computed using the two points. The unshaded values of m are entered by hand.)
_____
I'll write a couple of equations in each group so you can see how the spreadsheet numbers relate:
y = mx +b
1. y = 2x -7
3. y = 2/3x +4
8. y = 1/3x -5
9. y = -5/2x +4

Answer:
3/4 of 24 is 18 and 2 and 3/4 (11/4) of 24 is 66.
Step-by-step explanation:
First, divide 24/4.
24/4 = 6
Multiply by 3.
6 x 3 = 18 ( or 24 x 3/4 )
2 and 3/4, or 11/4 = 2.75.
Multiply 24 by 2.75 (or 11/4) to get 66

The mean of 4 numbers is 40 what is the sum of the 4 numbers
Answers
Answer:44.445
Step-by-step explanation:
Let the 5 numbers are a,b,c,d, and e
so (a+b+c+d+e)/5=40
So a+b+c+d+e=5*40=200
Now let the next 4 no are p,q,r,s then
(p+q+r+s)/4=50
p+q+r+s=200
Thus sum of all 9 numbers
=(a+b+c+d+e) +(p+q+r+s)
=200+200=400
thus average of these 9 numbers
If the mean of 4 numbers is 40. Then the sum of the numbers will be 160.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean.
The mean of 4 numbers is 40.
Mean = (Sum of the number) / (Number of the observation)
Mean = 40
Number of the observation = 4
Then the sum of the numbers will be
40 = (Sum of the number) / 4
Sum of the numbers = 160

Students are making ornaments and each takes 1/4 of a piece of Bristol board. They go to the cupboard and find 2 1/2 pieces of Bristol board. How many ornaments can they make?
Answers
Answer: 10 ornaments
Step-by-step explanation:
From the question, we are informed that students are making ornaments and each takes 1/4 of a piece of Bristol board. We are further told that they go to the cupboard and find 2 1/2 pieces of Bristol board.
The number of ornaments that they make will be gotten by dividing 2 1/2 by 1/4. This will be:
= 2 1/2 ÷ 1/4
= 5/2 ÷ 1/4
= 5/2 × 4/1

you get this by equaling the two y= equations to each other so 9x=2x+49 then you would solve algebraically to get x so 7x=49.
X=7
Then you would go back to the two original y= equations and place the value of x into the equation to find the value of y so
Y=9(7)
Y=63 and if you want to check it to make sure its right you can place it into the other y= equation and the values should be the same and in this case they are so the values are correct .
