Out of 600 students who complete the proficiency test, 423 were found to be proficient in reading, 398 were found to be proficient in math, and 512 were found to be proficient in either reading or math. How many were proficient in both reading and math?
Answer:
309 students
Step-by-step explanation:
Out of 600 students who complete the proficiency test, 423 were found to be proficient in reading, 398 were found to be proficient in math, and 512 were found to be proficient in either reading or math. How many were proficient in both reading and math?
We solve the above question using the formula below:
Where R = Proficiency in reading
M = Proficiency in maths
n ( R ∪ M) = n(R) + n ( M) - n ( R ∩ M)
n ( R ∪ M) = 512 students
n(R) = 423
n ( M) = 398
n ( R ∩ M) = ??
Hence:
512 = 423 + 398 - n ( R ∩ M)
n ( R ∩ M) = 423 + 398 - 512
= 821 - 512
= 309
The number of people proficient in both reading and math [n ( R ∩ M)] = 309 students

2 tons of sand cost $2,120.00. What is the price per pound?
Answer:
424000
Step-by-step
Answer: $0.53 Per Pound.
Work: I did 2 tons divided by $2120. But, before I did the division, I made sure that the 2 tons were in pounds. 1 ton is 2000 pounds, so it's of course 4000 pounds. So, 2120/4000. After the division, I got 0.53 per pound
Check: 0.53 x 4000 = 2120. (Check)

can someone help with this?
pleasseeee help I'll give you brainlest answer
Answer:
The value of x is 10
Step-by-step explanation:
The measure of the exterior angle at one vertex of a triangle equals the sum of the measures of the two opposite interior angles to this vertex.
In ΔNOP
∵ ∠OPQ is an exterior angle of the triangle at vertex P
∵ ∠PNO and ∠NOP are the opposite interior angles of vertex P
→ By using the rule above
∴ m∠OPQ = m∠PNO + m∠NOP
∵ m∠OPQ = (6x - 15)°
∵ m∠PNO = (2x + 18)°
∵ m∠NOP = (2x - 13)°
→ Substitute them in the equation above
∴ 6x - 15 = 2x + 18 + 2x - 13
→ Add the like terms in the right side
∵ 6x - 15 = (2x + 2x) + (18 - 13)
∴ 6x - 15 = 4x + 5
→ Subtract 4x from both sides
∵ 6x - 4x - 15 = 4x - 4x + 5
∴ 2x - 15 = 5
→ Add 15 to both sides
∵ 2x - 15 + 15 = 5 + 15
∴ 2x = 20
→ Divide both sides by 2 to find x
∴ x = 10
∴ The value of x is 10

Given the table below that lists points on a line, what is the x-intercept of the line?
Answer:
Option (1)
Step-by-step explanation:
X-intercept means, value of x (input value) at y = 0 (output value).
Or an ordered pair in the form of (x, 0) is the x-intercept.
From the table attached,
At x = 9, output value is y = 0.
Therefore, x-intercept of the line represented by the table will be,
x = 9
Option (1) will be the correct option.
Sylvie finds the solution to the system of equations by graphing.
y=2/3x+1 and y = -2/3 x-1
Which graph shows the solution to Sylvie's system of equations? Plz help, it’s 15 points lol!!
Answer:
From the graph, it is clear that both lines intersect
at x=0 and y=2/3 or (0.667)
Therefore, the solution is: (x, y) = (0, 2/3) or (0, 0.667)
Step-by-step explanation:
Given the system of equations
y=2/3x+1 and y = -2/3 x-1
GRAH AND POINT OF INTERSECTION (SOLUTION)
The solution graph is attached below.
From the attached solution graph,
The red line is representing the equation y=2/3x+1 The blue line is representing the equation y = -2/3 x-1From the graph, it is clear that both lines intersect
at x=0 and y=2/3 or (0.667)
Thus, the point of intersection is (x, y) = (0, 2/3) or (0, 0.667)
Therefore, the solution is: (x, y) = (0, 2/3) or (0, 0.667)

b 5 3 a 4 What is the length of the hypotenuse of this triangle? 3 units 5 units 4 units
Answer:
5 units
Step-by-step explanation:
The hypotenuse is always the longest segment on a triangle. If the lengths of the sides of this triangle are 3 units, 4 units, and 5 units, the hypotenuse will be 5 units. You can use the pythagorean theorem to check.
a^2+b^2=c^2
If you substitute the variable with the lengths of the legs in ascending order, you will get 3^2+4^2=5^2. Simplifying the equation, you will get 9+16=25, or 25=25. Thus, proving the equation.
Hope this helped! :)
Find the equation of the line that contains the point (-2, -1) and is perpendicular
to the line 2x + 3y = 9. Write the line in slope-intercept form, if possible. Graph the
lines
Select the correct choice below and fill in the answer box to complete your
choice.
O A. The equation of the perpendicular line in slope-intercept form is
(Simplify your answer. Type your answer in slope-intercept form. Use
integers or fractions for any numbers in the equation.)
B. The equation of the perpenditular line cannot be written in
slope-intercept form. The equation of the perpendicular line is
(Simplify your answer. Use integers or fractions for any numbers in the
equation.)
Answer:
The line equation in the slope-intercept form:
[tex]y=\frac{3}{2}x+2[/tex]
Step-by-step explanation:
We know that the slope-intercept of line equation is
[tex]y = mx+b[/tex]
Where m is the slope and b is the y-intercept
Given the line
[tex]2x + 3y = 9[/tex]
Writing in the slope-intercept form
[tex]2x + 3y = 9[/tex]
[tex]y=-\frac{2}{3}x+3[/tex]
Therefore, the slope of the line = m = -2/3
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = -2/3
perpendicular slope = – 1/m
[tex]=-\frac{1}{-\frac{2}{3}}=\frac{3}{2}[/tex]
Given the point
(x₁, y₁) = (-2, -1)
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope and (x₁, y₁) is the point
substituting the perpendicular slope m = 3/2 and the point (-2, -1)
[tex]y-\left(-1\right)=\frac{3}{2}\left(x-\left(-2\right)\right)[/tex]
Writing in the slope-intercept form
[tex]y+1=\frac{3}{2}\left(x+2\right)[/tex]
subtract 1 from both sides
[tex]y+1-1=\frac{3}{2}\left(x+2\right)-1[/tex]
[tex]y=\frac{3}{2}x+2[/tex]
Thus, the line equation in the slope-intercept form:
[tex]y=\frac{3}{2}x+2[/tex]

Answer:
The answer is 183
Step-by-step explanation:
Given the function f(x) = 2x + 1, find x if f(x) = 15.
Answer:
x = 7
Step-by-step explanation:
15=2x+1
2x+1=15
2x+1−1=15−1
2x=14
2x /2 = 14 /2
x = 7
Let y = f(x)
[tex]y = 2x + 1[/tex]
When y=15
[tex]15 = 2x + 1 \\ 2x = 15 - 1 \\ 2x = 14 \\ x = 7[/tex]
Therefore, x = 7 when f(x)=15
The cost of 2kg orange is 3/2 times the cost of 1 kg mangoes.If mana purchased 4 kg of oranges for 250 rupees then find the cost of oranges and mangoes per kg
Answer:
Orange per kg = 62.5 rupees
Mango per kg = 39.0625 rupees
Step-by-step explanation:
Given that:
Cost of 2kg orange = 3.2 times the cost of 1kg mango
If 4 kg oranges = 250 ruppess
The cost per kg of mangoes and oranges is :
Cost of orange per kg:
Cost of 4kg / number of kg
250 / 4 = 62.5 ruppess
Cost of 2kg orange = 3.2 times the cost of 1kg mango
Let cost of 1 kg mango = x
2 * 62.5 = 3.2 * x
125 = 3.2x
x = 125 / 3.2
x = 39.0625
can i have some help
Answer:
First one is 0 aka no slope and second one is 2
Step-by-step explanation:
y = mx + b
m represents the slope b is the y-intercept
The first one is y = -5, as we can see there's no x so it's safe to say that the slope is 0 cause, 0x = 0 times x = 0
Second one is y = 2x - 4, in place of m we have 2 so the slope is 2
Answer:
the slope for the first one is 0
the second one is 2
Step-by-step explanation:
1. set your equation into y=mx+b form
2. identify what your 'm' is
3. m= your slope

Step-by-step explanation:
Gertrude is making goodie bags for her birthday party. She has 18 erasers and 12 pencils. She wants her bags to have the same combinations of pencils and erasers. Name two possible combinations of bags she could have.
The two possible combinations not and she could have is calculated as :
a) Greatest Possible Combination
We solve using Greatest Common Factor Method
The factors of 12 are: 1, 2, 3, 4, 6, 12
The factors of 18 are: 1, 2, 3, 6, 9, 18
Then the greatest common factor is 6.
Hence, the greatest number of bags she could have is 6 bags
b) Least Possible Combination
We solve using Least Common Multiple Method
Multiples of 12:
12, 24, 36, 48, 60
Multiples of 18:
18, 36, 54, 72
Therefore,
LCM(12, 18) = 36
The least possible combination of bags she could have is 36 bags
