Step-by-step explanation:
since there is triangle , you use the formula
1/2 × b × h
as you can see the base is 6 and the height is 4, so
1/2 × b × h
= 1/2 × 6 × 4
=12
12 × 2 = 24 , you times by 2 because there is 2 triangle
There is also rectangle in the diagram, so you use the formula , length × breadth , the length is 8 and the breadth is 5, so
length x breath
= 5 × 8
=35
35 × 2 = 70 , times by 2 because you can see 2 rectangles with the same length and breadth
length x breath
= 8 × 6
= 48
this one is different because the length is 8 and the breadth is 6.
SA = 48 + 35 + 24

Answers
The price of one pen will be $1.5 and one highlighter is $4.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.
Given that:-
Frank bought 6 pens and 3 highlighters in the school store and paid $21 for the whole purchase.His friend, Andy paid $19 for 2 pens and 4 highlighters.The cost of the pen and the highlighter will be calculated by forming the two expressions from the given data in the question the expressions are as follows:-
6p + 3h = 21
2p + 4 h = 19
Solving the above linear equations by elimination method:-
( 6p + 3h = 21 ) x 2
( 2p + 4 h = 19 ) x 6
The new equations are:-
12p + 6h = 42
12p + 24h = 114
Substracting the below equation from the above equation we will get:-
6h - 24h = -72
-18 h = -72
h = $4
Put the value of h in any of the above equations:-
2p + 4 h = 19
2p + 4 ( 4 ) = 19
2p + 16 = 19
p = 3 / 2
P = $1.5
Therefore the price of one pen will be $1.5 and one highlighter is $4.

What is Similar Triangle?Similar triangles are the triangles that have corresponding sides in proportion to each other and corresponding angles equal to each other.
Here, mark the park as A, Home as B, Library as C and field as D.
Now, CD = 18 miles
BC = 4 miles
we have to find AC (distance between library and park)
BD = BC + CD = 18 + 4 = 22 miles
Using property of similar triangles,
AD² = BD X CD
AD² = 22 X 18
AD = √22 X √18
AD = 6√11 miles
By Pythagoras theorem,
AD² = AC² + CD²
396 = AC² + 324
AC² = 396 - 324
AC² = 72
AC = √72
AC = 6√2 miles
Thus, the distance between library and park is 6√2 miles and the distance between park and field is 6√11 miles.

Answers
from equation so:
5(x+y) =5 (0) => x+y=0
and by solving for × using elimination method
-8x+y=36
x+y=0
by subtracting both x and y we get
-9x=36 => x=-4
by inputing × into the "x+y=0" equation so we get:
-4+y=0 => y=4
Answer:
x= -4, y = 4.
Step-by-step explanation:
first, divide the first equation by its G.C.D (5), to obtain its simplest form.
5x/5 + 5y/5 = 0/5 to obtain x + y = 0.
Then, find the value of y by rearranging the second equation.
y = 36 + 8x. (Rem; when 8x moves to the other side of the equation, it changes the sign)
Now substitute the value of y (36 + 8x) in the first equation which is x + y = 0.
x + 36+8x = 0
Put like terms together.
36 + 9x = 0
move 9x to the other side and change its sign.
36 = -9x
divide both sides by 9,
x = -4.
Lastly, find the value of y by replacing the value of x in either equation.
-8(-4) + y = 36
32 + y = 36
rearrange to obtain
y = 36 - 32
y = 4.

Please help!
Answers
Answer:
(14, -2)
Step-by-step explanation:
The coordinates of the midpoint is equal to the mean of the coordinates of the endpoints.
=============================================================
Solving :
⇒ 5 = -4 + x / 2
⇒ x - 4 = 10
⇒ x = 14
⇒ 2 = 6 + y / 2
⇒ y + 6 = 4
⇒ y = -2
===========================================================
Coordinates of Point Y :
⇒ Y = (x, y)
⇒ Y = (14, -2)
Answer:
Y (14, - 2 )
Step-by-step explanation:
using the midpoint formula for (x₁, y₁ ) and (x₂, y₂ ) , then
midpoint = ( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1+y_{2} } }{2}[/tex] )
equating the x- coordinates and the y- coordinates
let coordinates of Y = (x, y )
[tex]\frac{x-4}{2}[/tex] = 5 ( multiply both sides by 2 )
x - 4 = 10 ( add 4 to both sides )
x = 14
and
[tex]\frac{y+6}{2}[/tex] = 2 ( multiply both sides by 2 )
y + 6 = 4 ( subtract 6 from both sides )
y = - 2
coordinates of Y = (14, - 2 )
if the area of a square is 32ft how long is the diagonal?
Answers
A square has the same length all 4 sides, therefore in order to find the length of the sides, you would need to find the square root of 32, which would be 5.66 or 4 radical 2. Then to find the diagonal length you would need to split the square diagonally resulting in 2 triangles. We know the side lengths of the triangles but not the hypotenuse( longest side of triangle), which is the diagonal length. To figure this out we would use the Pythagorean theorem a^2 + b^2 = c^2. We know what a and b are so we substitute, do basic algebra, and find that c is equal to 8
Answer: 8
Step-by-step explanation:
To find the diagonal, we need to use two formulas:
Area of a square: [tex]A = s^{2}[/tex] (Area = side * side)
Pythagorean Theorem: [tex]a^{2} +b^{2} =c^{2}[/tex]
Since every side of a square is the same:
[tex]a^2 = b^2\\a = b = \sqrt{32} \\a^{2} = 32\\b^2 = 32[/tex]
Our equation:
[tex]32 + 32 = c^2\\64 = c^2\\8 = c[/tex]

If he is standing at a horizontal distance of 331 meters from the base of the skyscraper, what is the height of the skyscraper? Round your answer to the nearest tenth of a meter if necessary.
Answers
The height of the skyscraper is 177.51 m which is 331 m from the base of skyscraper.
What is Trigonometric Ratio?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Here, h₀ = 1.52 m, angle of elevation = 28⁰
d = 331 m
Now, tan 28⁰ = h/d
h = d. tan 28⁰
h = 331 X 0.5317
h = 175.99 m
Total height = h + h₀
= 175.99 + 1.52
= 177.51 m
Thus, the height of the skyscraper is 177.51 m which is 331 m from the base of skyscraper..

Answers
The average rate of change of the number of miles with respect to the number of gallons is 14.5 miles per gallon
How to determine the average rate of change?The given parameters can be represented as:
M(0) = 30680
M(20) = 30970
The average rate of change is calculated as:
M'(t) = (M(20) - M(0))/(20 - 0)
This gives
M'(t) = (30970 - 30680)/(20 - 0)
M'(t) = 14.5
Hence, the average rate of change of the number of miles with respect to the number of gallons is 14.5 miles per gallon
The average rate of change of M as t changes from 8 to 16.
This is calculated using
M'(t) = (M(16) - M(8))/(16 - 8)
M'(t) = (20 - 10)/(16 - 8)
M'(t) = 1.25
The average rate of change of M as t changes from 16 to 24.
This is calculated using
M'(t) = (M(24) - M(16))/(24 - 16)
M'(t) = (25 - 20)/(24 - 16)
M'(t) = 0.625
The average rate of change of M as t changes from 24 to 32.
This is calculated using
M'(t) = (M(32) - M(24))/(32 - 24)
M'(t) = (25 - 25)/(32 - 24)
