If you place brackets or parenthesis around the numbers 19+7 and 2*6+1. It would appear as follows: (19+7)/(2*6+1) = 26/13 = 2. It takes special parenthetical treatment to express the mathematical expression 19+7/26+1 to get a result of 2.
What is expression?An expression in mathematics is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.) You can think of expressions as being similar to phrases. A phrase in language may contain an action on its own, but it does not constitute a complete sentence.
Here,
y=19+7/2×6+1
becomes
y=(19+7)/(2×6+1)
y=26/(12+1)
y=26/13
y=2
If you enclose the numbers 19+7 and 2*6+1 in parenthesis or brackets. It would look like this: (19+7)/(2*6+1) = 26/13 = 2. The mathematical expression 19+7/26+1 must be expressed with special parenthetical treatment to yield the number 2.

Can anyone solve this, tommorow is my exam
Answer:
∠L = 113°∠O = 67°Step-by-step explanation:
Given a transversal crossing parallel lines and supplementary angles (x+8°) and (2x-5°), you want to find the measures of angles L and O, supplementary to each of these.
Consecutive interior anglesWhere a transversal crosses parallel lines, consecutive interior angles are supplementary. Using the given expressions, this means ...
(x +8°) +(2x -5°) = 180°
3x +3° = 180° . . . . . . . . . simplify
x +1° = 60° . . . . . . . divide by 3
x = 59° . . . . . . subtract 1°
Then the acute angle is ...
x+8° = 59° +8° = 67°
and the obtuse angle is ...
2x -5° = 2(59°) -5° = 113°
Relation to other anglesAngle L corresponds to angle (2x-5°), so is congruent:
∠L = 113°
Angle O is an alternate interior angle with respect to angle (x+8°), so is congruent:
∠O = 67°

how can I covert this 0.688= to a fraction
You have to convert the following number into a fraction:
[tex]0.6\bar{8}\bar{8}[/tex]This is a periodic decimal number, which explicitely is 0.68888888....
In order to convert this number to a fraction you proceed as follow:
[tex]0.6\bar{8}=\frac{68-0}{99}=\frac{68}{99}[/tex]You put 0.68 and not 0.688 because to do the convertion you need only the first periodic number (that is, only the first 8). The key is to put in the numerator the complete number as whole number, that is, 68. To this number you subtract the whole part of the decimal number, this whole part is 0 because of the 0.688. Then, in the numerator you have 68 - 0. In the denominator you write a number composed only by 9's. The number of 9 numbers is determined by the number of digits of the first number in the numerator. That is two 9 numbers
Please help with this problem g(0)=9, g(8)=7
The equation of the line is g(x) = -1/4x + 9.
Given,
g(0) = 9
g(8) = 7

Ray had scores of 75, 82, 94, and 77 on his first four algebra tests. What must he score on the next test to have an average of at least 85?
Please show work as well if possible.
Answer:
x ≥ 97
Step-by-step explanation:
Average = Sum of values divided by the amount of numbers in a data set
Data Set: {75, 82, 94, 77, ?}
75 + 82 + 94 + 77 + ? = ? ÷ 5 = 85
85 x 5 = 425
75 + 82 + 94 + 77 + ? = 425 ÷ 5 = 85
75 + 82 + 94 + 77 = 328
425 - 328 = 97
Ray must score greater than or equal to 97, or x ≥ 97 in order to have an average of at least 85.

the circumference of a sphere was measured to be 80 cm with a possible error of 0.5 cm. (a) use differentials to estimate the maximum error (in cm2) in the calculated surface area. (round your answer to the nearest integer.) cm2 what is the relative error? (round your answer to three decimal places.) (b) use differentials to estimate the maximum error (in cm3) in the calculated volume. (round your answer to the nearest integer.) cm3 what is the relative error? (round your answer to three decimal places.)
a) the maximum error in surface area and the relative error is 25.4 cm² and 1.25%
b) the maximum error in the volume and the the relative error is 162.1 cm³ and 1.875%
As we know the formula for surface area is
Surface Area , S= 4*π*r^2.
So differentiating both sides we get
dS/dr = 8*π*r .....1
and the formula for the circumference is :2*π*r
, so the error on the circumference will be respect to radius
=> Δc = 2*π*Δr
=> Δr = ΔC / (2*π)
substituing the value ofΔr in the equation 1, we get
The maximum error in surface area which is :
ΔS = 8*π*r*Δr = 4*r*Δc
= (2/π)*c*Δc.
= 25.4
where for the relative error
ΔS/S = 4*r*Δc/(4*π*r^2)
= Δc/(π*r)
= 2*Δc/c
= 1.25%
Now Since the formula for the volume of a sphere is :
V = 4/3*π*r^3
dofferentiating both sides we get ,
=> dV/dr = 4*π*r^2.
So, the the maximum error in the calculated volume will be :
ΔV = 4*π*r^2*Δr
= 2*r^2*Δc
= 1/(2*π^2)*c^2*Δc
=162.1
Where as the relative error for the volume will be
ΔV/V = 3*Δr / r = 3*ΔC/C = 1.875%

Eric ordered a set of red and yellow pins. He received 70 pins in all. 21 of the pins were red. What percentage of the pins were red?
The percentage of red pins in total pins ordered by Eric is 30%.
According to the question,
We have the following information:
Eric received 70 pins in all.
21 of the pins are red.
Now, we will find the percentage of red pins:
Percentage of red pins = (Number of red pins*100/total number of pins)
Percentage of red pins = (21*100)/70
Percentage of red pins = 2100/70
Percentage of red pins = 30%
(In the same way, we can also find the number and percentage of yellow pins from the total pins.)
Hence, the percentage of red pins in total pins ordered by Eric is 30%.

A.5x³+4x²+x³
B.5x+4x³+x²
C.6x³+4x²+x³
D.6x² + 4x³+x²
The volume of the given rectangular prism is V = 5x⁵ + 4x⁴ + x³ cubic units.
What is the volume of the rectangular prism?
Four rectangular faces and two parallel rectangular bases make up a rectangular prism. We are aware that a rectangular prism's cross section is a rectangle. The term "Cuboid" is another name for the rectangular prism.
Therefore, the following formula is provided to determine a rectangular prism's volume: Volume = l*b*h cubic units.
Given, the length of the rectangular prism = l = x
Also, the width of the rectangular prism = w = x²
Again, the height of the rectangular prism = h = 5x² + 4x + 1
Volume of the rectangular prism = l*w*h = x*(x²)*(5x² + 4x + 1)
= x³(5x² + 4x + 1) = 5x⁵ + 4x⁴ + x³
Thus, the volume of the given rectangular prism is V = 5x⁵ + 4x⁴ + x³ cubic units.

Third-degree, with zeros of −3, −1, and 2, and passes through the point (3,11)
The polynomial with zeros of −3, −1, and 2, and passes through the point (3,11) is:
P(x) = (11/24)*(x + 3)*(x + 1)*(x - 2)
How to get the polynomial?We know that the zeros are −3, −1, and 2, so if we define the leading coefficient as A, the polynomial can be written as:
p(x) = A*(x + 3)*(x + 1)*(x - 2)
Now we want this to pass through the point (3, 11), then we get:
p(3) = 11 = A*(3 + 3)*(3 + 1)*(3 - 2)
11 = A*6*4*1
11 = A*24
11/24 = A

What is the perimeter of a triangle?The length of a triangle's boundary taken as a whole is referred to as its perimeter.A triangle is a polygon with three sides, and depending on the size of the sides and angles, there are various varieties of triangles.Any 2D shape's perimeter is determined by the total distance encircling it.Since perimeter indicates how long a shape's perimeter is, it is given in linear units.Calculate the perimeter of a triangle:
Perimeter of a triangle = a +b + c
a = 2 *9 = 18b = 2 * 7 = 14c = 2 * 7.2 = 14 .4a +b + c = 18 +14 +14.4 = 46.4Therefore, the triangle's perimeter is 46.4, and the whole length of a triangle's boundary is referred to as the triangle's perimeter.

What is Equation of line ?
A straight line's general equation is y = mx + b, where m denotes the gradient and y = b denotes the point at which the line crosses the y-axis. On the y-axis, this value b is referred to as the intercept.
The given point are (5, 1) and (7, 11)
We know, the equation of line is,
y = mx + b
where, m = slope
b = y-intercept
First, find slope i.e m
we know the formula of slope (m) = (y2 - y1) / (x2 - x1)
The points, (x1, x2) = (5, 1) and,
(y1, y2) = (7, 11)
put these values in slope formula,
m = (11 -7) / (1 - 5)
= 4 / -4
m = -1
we get the slope is -1
Next, find y-intercept i.e 'b'
for that, take any one point I'm taking (5, 1) and put these in equation ,
y = mx + b
1 = -1 * 5 + b
1 = -5 + b
b = 6
Now, put slope (m) and y-intercept (b) value in ,
y = mx + b
