You are asked to create a solution that is 3 parts water and 2 parts bleach. You have 4 liters of bleach. How much water should you add?
Step-by-step explanation:
If this is 3L water : 2L bleach then this following measures and answers are the answer.
3L:2L
?L:4L
4L/2L= 2L
so therefore
3L* 2L = 6L
so
6L water : 4L bleach
6L water
You are given that a = 6.54 (to 3 significant figures) and b = 123 (to 3 significant figures).
Calculate upper and lower bounds for each of the following, give your answers to 3 significant figures:
(a) a + b
(b) ab
(c) a/b
(d) b - 1/a
The upper and lower bounds for the numbers are illustrations of approximation
How to calculate the upper and lower boundsThe numbers are given as:
a = 6.54 (to 3 significant figures)
b = 123 (to 3 significant figures)
(a) a + b
We have:
a + b = 6.54 + 123
a + b = 129.54
When approximated, the bounds to three significant digits are:
Lower bound = 129
Upper bound = 130.1
(b) ab
We have:
ab = 6.54 * 123
a + b = 804.42
When approximated, the bounds to three significant digits are:
Lower bound = 804
Upper bound = 805
(c) a/b
We have:
a/b = 6.54/123
a/b = 0.0531707317
When approximated, the bounds to three significant digits are:
Lower bound = 0.0531
Upper bound = 0.0532
(d) b - 1/a
We have:
b - 1/a = 123 - 1/6.54
b - 1/a = 122.847094801
When approximated, the bounds to three significant digits are:
Lower bound = 122
Upper bound = 123

Determine if (0,-5) is a
solution to the equation
y = -5x
Plug (0,-5) into the equation -
-5 = -5(0)
-5 times 0 is 0
-5 = 0
(0,-5) is NOT a solution to the equation.
Good luck!
Answer:
No, it is not the solution to the equation.
Step-by-step explanation:
(0, -5)
y = -5x
So we have to plug in the values for x and y. 0 is our x value and -5 is our y value.
-5 = -5(0)
-5 = 0
Therefore, (0, -5) is not a solution to the equation

Please solve ASAP. Solving quadratic equations by factorising
Answer:
x = 1 , x = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
2x² - 5x + 3 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × 3 = 6 and sum = - 5
The factors are - 2 and - 3
Use these factors to split the x- term
2x² - 2x - 3x + 3 ( factor the first/second and third/fourth terms )
2x(x - 1) - 3(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(2x - 3) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

Answer:
y = -1/5x - 10
Step-by-step explanation:
Pick any two points on the line.
(0,-10) and (50,-20)
find the slope by using m = y2-y1/x2 - x1(rise over run)
m = -20-(-10) / 50 - 0
m = -10/50 = -1/5 -- this is your slope
slope intercept form is y = mx + b, but we need to find your b, which is your y intercept. you find this by asking yourself, what is the y coordinate when x = 0? It is -10.
so now you have all the points you need.
y = mx + b
y = -1/5x - 10

Find the value of x.
Answer:
x = 25
Step-by-step explanation:
Internal angles of a triangle = 180 degrees
So knowing this we can form the following equation
(x + 26) + (x + 14) + (4x - 10) = 180
Simplify
(x + x + 4x) + (26 + 14 - 10) = 180
6x + 30 = 180
Rearrange for x
6x = 180 - 30
6x = 150
x = 25

What is the y-intercept:
7x + y = 10
Answer:
10
Step-by-step explanation:
7(0)+y=10
y=10
Answer: (0, 10)
Step-by-step explanation:
The given expression is in the standard form of linear equations: Ax + By = C, where A and B are constants.
The definition of y-intercept is the point that intersects with the y-axis, meaning that the [x] value of the point will be zero.
To find the y-intercept of an equation, substitute the [x] variable with 0, as mentioned above, the [x] value of a y-intercept is 0.
[tex]7x+y=10\\[/tex]
[tex]7(0)+y=10[/tex]
[tex]0+y=10[/tex]
[tex]y=10[/tex]
As we find the [y] value is 10, while the given [x] value is 0, therefore, the y-intercept of [tex]7x+y=10[/tex] is [tex]\boxed{(0,10)}[/tex].

What is the quotient of −112÷2 1/3 ?
Answer:
-48
Step-by-step explanation:
−112÷2 1/3 needs to be rewritten as -112 / (7/3), where 7/3 is the improper fraction version of 2 1/3.
Then we have
-112
---------
7/3
Recall that division by a fraction is equivalent to multiplication by the reciprocal of the fraction; thus, the above expression becomes
-112 * 3
-----------
7
This, in turn, can be reduced through division to -16*3, which equals -48.
bChoose the equation that represents the graph.
Oy = x - 3
Oy = -x + 3
Oy = -x-3
Oy = x + 3
The graph illustrates a linear function, because the graph is a straight line
The equation of the graph is (d) y = x +3
The points on the line are:
[tex](x_1,y_1) = (-3,0)[/tex]
[tex](x_2,y_2) = (0,3)[/tex]
First, we calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute values for x1, x2, y1 and y2
[tex]m = \frac{3-0}{0--3}[/tex]
Simplify
[tex]m = \frac{3}{3}[/tex]
Divide
[tex]m = 1[/tex]
The equation of the line is then calculated using the following formula:
[tex]y = m(x - x_1) + y_1[/tex]
Substitute values for m, x1 and y1
[tex]y = 1(x - -3) + 0[/tex]
Simplify
[tex]y = 1(x +3)[/tex]
Open bracket
[tex]y = x +3[/tex]
Hence, the equation of the graph is (d) y = x +3

Which is the coordinate of point A?
(8, –6)
(–6, 8)
(6, –8)
(–8, –6)
Answer:
Option A is your definite answer.
Step-by-step explanation:
We know that the x coordinate is positive since it is on the positive half of the x-axis. We also can identify that the point A is in the 4th Quarter of the grid, so the y coordinate is negative.
The only choice that proves this reasoning true is option A :)
