Answer: it's 248 I just did the question .
Step-by-step explanation:
make x the subject m=x+a/b-k
Answer:
x = m - a/b + k
Step-by-step explanation:
m = x + (a / b) - k
switch sides
x + a/b - k = m
subtract a/b - k from both sides
a + a/b - k - (a/b - k) = m - (a/b - k)
therefore,
x = m - a/b + k

Members of a community center have decided to paint a large circular mural in the middle of the parking lot. The radius of the mural is to be 11 yards. Before they begin painting the mural, they use a rope to form the outline. How many yards of rope will they need?
Answer:
69.124 yards of ropeStep-by-step explanation:
This problem bothers on the mensuration of flat shapes, circles.
given that the members of the community used rope as outline for the circular shape mural.
we can tell that the perimeter of the mural is same as the perimeter of the rope.
Hence the length of rope used is same as the perimeter of the circular mural.
we know that the perimeter of a circle is given as
[tex]C=2\pi r\\\\[/tex]
substituting radius r= 11 yards
we have
[tex]C= 2*3.142*11\\\\C= 69.124 yards[/tex]
Determine the form of the following quadratic equation, and identify the values for the key characteristic of the parabola revealed by that form. f(x)=(2x−1)(x+6)
Answer:
1) The equation is given in factored form
2) The key characteristics of the parabola are;
a. The parabola has 2 real roots and extends to infinity on both sides
b. The x-intercepts of the parabola are (1/2, 0) and (-6, 0)
c. The y intercept is (0, -6)
d. The vertex point is (-2.75, -21.125)
Step-by-step explanation:
The given equation is f(x) = (2·x -1)(x + 6)
Therefore the equation is given in factored form
The key characteristic of the parabola revealed from the form f(x) = (2·x -1)(x + 6) are;
1) Writing the parabola in the intercept form, a(x - p)(x -q) we have;
f(x) = (2·x -1)(x + 6) = 2·(x - 1/2)(x + 6)
p = 1/2, q = -6
Therefore;
Given that a is positive the parabola is concave upwards
2) a. The parabola has 2 real roots and extends to infinity on both sides
b. The x-intercepts of the parabola are p and q which are (1/2, 0) and (-6, 0)
c. The y intercept is a·(-p)·(-q) = 2×(-1/2)×6 = -6
The y intercept is (0, -6)
d. Expanding we get;
f(x) = 2·x² + 11·x - 6
From the
The vertex is h = -b/(2·a) = -11/(2×2) = -2.75
h(2.75) = 2×(-2.75)² + 11×(-2.75) - 6 = -21.125
Therefore, the function is symmetrical about the vertex point (-2.75, -21.125)
Pls help with question 5 will mark braineliest
Answer:
Last year there were 1070 students.
Step-by-step explanation:
Since 856 students represent a 20% drop from last year's number of students, then 856 students is 80% of last year's number.
80% of x = 856
0.8x = 856
x = 856/0.8
x = 1070
Answer: Last year there were 1070 students.
Answer:
1070
Step-by-step explanation:
p = previous years populations
p - p 20% = 856
p - .20*p = 856
Combine like terms
.80p = 856
Divide each side by .8
.80p/.8 - 856/.8
p =1070
Solve for x 33x+10=5-2x
Our equation: 33x + 10 = 5 - 2x
Step 1:
To solve for x, we need to remember to isolate the variable (that is our way to solve for x). To do that, we add 2x on the right side of the equation to cancel -2x out. Then, we add 2x on the left of the equation. The equation becomes:
[tex]35x+10=5[/tex]
Step 2:
We subtract 10 from both sides (to cancel out the 10 on the left). Equation:
[tex]35x=-5[/tex]
Step 3: Divide 35 on both sides to get our x value.
[tex]\frac{35x}{35}=x\\\\\frac{-5}{35} =\frac{-1}{7}[/tex]
Answer: [tex]x=\frac{-1}{7}[/tex] Hope this helps!

1. Which range of numbers is most appropriate for the y-axis scale and interval on a graph given the
Range: 10 - 35; Interval 10
Range: 0-35; Interval: 5
Range: 0 - 30; Interval 5
Range: 10 - 30; Interval: 5
Answer:
Option B.
Step-by-step explanation:
We need to find the range of numbers is most appropriate for the y-axis scale and interval on a graph for given table.
From the given table it is clear that the minimum value of y is 10 and the maximum value of y is 34.
It means 10 and 34 must be included in the Range.
In option C and D 34 in not included in the range, so these options are incorrect.
In option A, 10 is the minimum value of range and interval of 10 is not possible for the range 10-35, because it contains only multiple of 10 on the y-axis. So, this option is incorrect.
In option B, both 10 and 34 are included and interval of 5 is possible for range 0-35.
Therefore, the correct option is B.
Use the i formation major of 1..... look at picture
Explanation:
You basically plug in x = 20, which is the same as saying "replace x with 20". Then you perform arithmetic to simplify each expression. Both simplify to 90, so angle 1 and angle 2 are the same measure. These angles are alternate interior angles, so we'll use the converse alternate interior angle theorem to conclude the lines are parallel.
Note: the alternate interior angle theorem says that if we have parallel lines, then the alternate interior angles are congruent. So the converse goes in reverse of this.

Answer:
t = (q - r) / rs
Step-by-step explanation:
Right now you have q=rst+r so if you want to find t you must move the variables around. Like this:
q=rst+r (or r+rst)
so so get rid of the r first
like this: (q-r)=rst
divide by rs to find t
so t=(q-r)/rs

What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
f(x) = -3x^4+2x^2-x
Now,
we can find the end behavior of f(x) = -3x^4 + 2x^2 - x:
The degree of f(x) is 4, which is even. Therefore, both ends of the graph will either go up or go down.
The leading coefficient of f(x) is -3, which is negative. Therefore, the right end of the graph will go down.
Since both ends have to go in the same direction, and the right end goes down, then the left end must also go down.
Therefore, by the given function the answer will be both ends go down

Jesse works in construction and is planning the layout of a client’s garage. The only requirement is for the length to be twice as long as the width. If the area of the garage must be 288 square feet, what must the dimensions be?
Answer:
Width = 12 foot
Length = 24 foot
Step-by-step explanation:
Let
Width=x
Length=2x
Area = 288 square feet
Area of the garage = Length × width
288 = 2x * x
288= 2x^2
Divide both sides by 2
288 / 2 = x^2
144= x^2
Find the square root of both sides
√144 = √x^2
12 = x
Therefore,
x=12
The dimensions will be:
Width = x
= 12
Length = 2x
=2(12)
=24
Width = 12 foot
Length = 24 foot

The difference between 30% of 400 and 15% of 400 is a.)200 b.)150 c.)60 d.)30
Answer:
C
Step-by-step explanation:
The difference between 30 and 15 is 15
then multiply the 15 % with 400
and you will get the value 60 which is the answer you want
Answer:
C. 60
Step-by-step explanation:
To find the difference between them, we must:
1. Find the amount of the percentage.
(Percent (%) is always over 100)
30% of 400 = 30/100 × 400/1
=12,000/100 = 120
So 30% of 400 is 120.
15% of 400 = 15/100 × 400
=6,000/100 = 60
So 15% of 400 is 60.
2. Then subtract the amount of the percentages to find their difference.
120 - 60= 60
So the difference between 120 and 60 is 60.

Answer:
The value of k is 46°.
Step-by-step explanation:
Given that when 2 angles add up together, they will form 75°.
So in order to find the value of k, you have to subtract 29° from 75° :
[tex]k + 29 = 75[/tex]
[tex]k = 75 - 29[/tex]
[tex]k = 46[/tex]
Answer:
46 degrees.
Step-by-step explanation:
The whole angle is 75 degrees. So you subtract the given value with the total angle. 75-29=46 degrees.
Kyle challenges you to a game. Each player rolls a standard number cube twice. If the sum of the results is divisible by 3, you win. If it is not, Kyle wins. What is your probability of winning? Is this a fair game?
Answer:
[tex]P(M) = \frac{1}{3}[/tex]
The game is not a fair game
Step-by-step explanation:
We start by listing out the sample space
Number Cube 1: {1,2,3,4,5,6}
Number Cube 2: {1,2,3,4,5,6}
Sample Space (S) of the sum of the 2 cubes;
[tex]S = \{2,3,4,5,6,7,3,4,5,6,7,8,4,5,6,7,8,9,5,6,7,8,9,10,6,7,8,9,10,11,7,8,9,10,11,12\}[/tex]
[tex]n(S) = 36[/tex]
Next, is to list out all multiples of 3; Represent this with M
[tex]M = \{3,6,3,6,6,9,6,9,6,9,9,12\}[/tex]
[tex]n(M) = 12[/tex]
Your probability of winning is the probability of M and is calculated as thus;
[tex]P(M) = \frac{n(M)}{n(S)}[/tex]
[tex]P(M) = \frac{12}{36}[/tex]
[tex]P(M) = \frac{1}{3}[/tex]
The probability of Kyle winning, P(K) = 1 - P(M)
[tex]P(K) = 1 - \frac{1}{3}[/tex]
[tex]P(K) = \frac{2}{3}[/tex]
The game is not a fair game because;
The probability of you winning and the probability of Kyle winning are not equal;
