Coordinate grid shown from negative 14 to positive 14 on x axis at intervals of 2, and negative 10 to positive 10 on y axis at intervals of 2. A triangle is shown with vertices labeled Library, Mall, and School. Library is the ordered pair negative 14, 6, Mall is the ordered pair 10, 6, and School is the ordered pair 10 and negative 4.
Britney traveled from the school to the mall and then from the mall to the library. Alice traveled directly from the school to the library. How many more miles did Britney travel than Alice? (1 point)
8 miles
9 miles
10 miles
12 miles
Answers
The direct distance from the school to the library, travelled by Alice can be
found using Pythagoras's theorem.
The number of miles Britney travelled more than Alice is; 8 miles
Reason:
The distance, d, between points given their coordinates, (x₁, y₁), (x₂, y₂) can
be found with the formula;
[tex]d = \sqrt{\left (x_{2}-x_{1} \right )^{2}+\left (y_{2}-y_{1} \right )^{2}}[/tex]
The above formula can be obtained using Pythagoras's theorem.
The distances travelled by Britney are;
Distance from the school to the mall = [tex]\sqrt{(10 - 10)^2 + (6 - (-4))^2}[/tex] = 10
Distance from the mall to the library = [tex]\sqrt{(-14 - 10)^2 + (6 - 6)^2}[/tex] = 24
Total distance travelled by Britney = 24 miles + 10 miles = 34 miles
The distance travelled by Alice is from the school to the library, which
gives; Alice's distance = [tex]\sqrt{(10 - (-14))^2 + (-4 - 6)^2}[/tex] = 26
Distance travelled by Alice from the school to the library is 26 miles
The number of miles more Britney traveled is 34 miles - 26 miles = 8 miles
Therefore;
Britney traveled 8 miles more than Alice

a + b + c = 80
Express a and c in terms of b using the ratios in fractional form, that is
[tex]\frac{a}{b}[/tex] = [tex]\frac{2}{3}[/tex] ( cross- multiply )
3a = 2b ( divide both sides by 3 )
a = [tex]\frac{2}{3}[/tex] b
[tex]\frac{b}{c}[/tex] = [tex]\frac{3}{11}[/tex] ( cross- multiply )
3c = 11b ( divide both sides by 3 )
c = [tex]\frac{11}{3}[/tex] b
Substitute the values for a and c into the original equation
[tex]\frac{2}{3}[/tex] b + b + [tex]\frac{11}{3}[/tex] b = 80 ( multiply through by 3 to clear the fractions )
2b + 3b + 11b = 240 , that is

To find the third side, we can use the Pythagorean Theorem.
The theorem states that if a triangle is a right triangle, and we already have two sides, we are able to find the third side.
The Pythagorean Theorem Formula is the following:
[tex]A^2+B^2=C^2[/tex]
A is any of the bases
B is the other base (you can make this the height)
C is the hypotenuse (the longest side)
We are given B and C, so lets plug them into our formula and solve for A.
[tex]A^2 + (4\sqrt{3} )^2=8^2[/tex]
Subtract [tex](4\sqrt{3} )^2[/tex] from both sides of the equation.
[tex]A^2=8^2 - (4\sqrt{3} )^2[/tex]
Now take the square root of both sides of the equation.
[tex]A=\sqrt{8^2 - (4\sqrt{3} )^2}[/tex]
Now plug this into your calculator and solve.
We get the answer to be:

The sum of four consecutive odd integers is 328. What are the integers? (show your work)
Answers
Answer:
79, 81, 83, and 85
Step-by-step explanation:
x = 1st integer
x+2 = 2nd
x+4 = 3rd
x+6 = 4th
328 = sum
x+x+2+x+4+x+6 = 328
328/4 = 82
The 4 integers are the 2 odd integers on either side of 82 and closest to 82
That would be 79, 81, 83, and 85.
79 + 81 + 83 + 85 = 328

Consider the figure below where MN is parallel to PQ, angle PTS is equal to (19x +5) and angle NST is equal to (17x +15), determine angle MSR and angle STQ
Answers
From the figure shown where MN is parallel to PQ:
m<MSR = 100°
m<STQ = 80°
By carefully observing the figure shown:
<MSR is vertically opposite to <NST
Vertically opposite angles are equal
m<NST = (17x + 15)
<NST is alternative to <PTS
Alternative angles are equal
Therefore, m<NST = m<PTS
m<NST = 17x + 15
m<PTS = 19x + 5
17x + 15 = 19x + 5
19x - 17x = 15 - 5
2x = 10
x = 10/2
x = 5
m<NST = 17x + 15
m<NST = 17(5) + 15
m<NST = 100°
Since m<MSR = m<NST
m<MSR = 100°
m<PTS = 19x + 5
m<PTS = 19(5) + 5
m<PTS = 100°
m<PTS + m<STQ = 180° (Sum of angles on a straight line)
100 + m<STQ = 180
m<STQ = 180 - 100
m<STQ = 80°
From the figure shown where MN is parallel to PQ:
m<MSR = 100°
m<STQ = 80°

The equation of a circle in the xy-plane is shown
above. What is the diameter of the circle?
Answers
The diameter of the equation of a circle in the xy-plane as shown is 26 units.
The standard form for finding the equation of a circle is expressed as:
[tex]x^2 + y^2 +2gx + 2fy +C= 0[/tex]
For us to get the diameter of the circle, we need to get the radius of the circle first calculated as shown:
[tex]r=\sqrt{g^2+f^2-C}[/tex]
Given the equation of the circle expressed as [tex]x^2 + y^2 - 6x + 8y = 144[/tex]
Compare with the general formula:
2gx = -6x
g = -6/2
g = -3
Similarly;
2fy = 8y
2f = 8
f = 4
C = -144
Substitute into the formula for calculating the radius;
[tex]r=\sqrt{(-3}^2+4^2-(-144)\\r=\sqrt{9+16+144}\\r=\sqrt{169}\\r=13units[/tex]
Get the diameter of the circle
d = 2r
d = 2(13)
d = 26 units
Hence the diameter of the equation of a circle in the xy-plane as shown is 26 units.

A. )True because, if we compare 52 to 27 and 49 to 24 they are exactly the same
distance apart on a number line. They just have different starting and ending points.
B.). True because, both 52-27 and 49-24 result in the same answer of 25.
C). False because, if 3 is subtracted from 52 to get 49, then, 49 and 27 more would not
equal 49 and 24 more. Putting together two larger numbers is not the same as
putting together two smaller numbers.
D). False because 52 + 27 does not equal 49
.
Answers
False because if 3 is subtracted from 52, then 49 and 27 more would not equal 49 and 24 more. Putting together two larger numbers is not the same as putting together two smaller numbers.
=======================================================
Explanation:
If we break up 52 into 49+3, then we can do the following rearrangement.
52 + 27 = 49 + 24
49 + 3 + 27 = 49 + 24
3 + (49+27) = 49 + 24
Notice that the 49+27 on the left is clearly larger than 49+24 on the right, mainly due to the 27 being larger than 24.
Then adding on 3 more means that the left side gets even larger.
So without having to add either side and simplify fully, we can see that the left side is larger than the right side. There's no way the two sides are the same number.
----------
Perhaps another quick way is to simply look at the units digits.
The 2 and 7 from 52 and 27 add to 2+7 = 9
The 9 and 4 from 49 and 24 add to 9+4 = 13 and we only care about the 3
The mismatch of the 9 and 3 is more evidence that the two sides aren't the same number.

Step-by-step explanation:
what is the problem here you don't understand ?
you understand the words "equality" and "inequality" ?
this is all about the question, if something is equal to something else or not - meaning of they are the same or at least the same size.
an expression without an equal ("=") or unequal sign ("<", ">", ">=", "<=", "<>" - if you don't understand these symbols, please ask, they are simply basic keyboard symbols for the scientific symbols) is not any form of that - no equality, and no inequality.
so,
1. is NOT
2. is NOT because it has an equality symbol
3. is a quadratic inequality (when doing the multiplication of both bracket terms, there will be an x×x=x² part) - it has a ">" (greater) symbol
4. is a quadratic inequality (there is a x² term as highest power of x included) - it has a "<=" (smaller or equal) symbol
5. is a quadratic inequality (there is a x² term as highest power of x included) - it has a ">" (greater) symbol

1. In a group of cows and chickens, the number of legs was 14 more than twice the number of heads. The number of cows was:
(a) 5, (b) 7, (c) 10, (d) 12, (e) 14
Solution:
Let the number of cows be x and their legs be 4x.
Let the number of chicken be y and their legs be 2x.
Total number of legs = 4x + 2y.
Total number of heads = x + y.
The number of legs was 14 more than twice the number of heads.
Therefore, 2 × (x + y) + 14 = 4x + 2y.
or, 2x + 2y + 14 = 4x + 2y.
or, 2x + 14 = 4x [subtracting 2y from both sides].
or, 14 = 4x – 2x [subtracting 2x from both sides].
or, 14 = 2x.
or, x = 7 [dividing by 2 on both sides].
Therefore, the number of cows = 7.
