Answer:
31 square units
Step-by-step explanation:
See the picture below.
Each full or almost full square was counted first. There are 24 of them.
Then parts of squares of counted together to add to 1 square. They are color coded in the figure below. After adding them all up, the total was 31.
The area of the irregular shape is,
⇒ 27.5 square units
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The irregular shape is very similar to a trapezium with coordinates are,
(-3,3), (2, 2), (2, -2) and (-3, -4).
Now, We know that;
Area of a trapezium is,
⇒ [(a + b)/2] × h
where, a and b refer to the two parallel sides and h is the distance between them.
Hence, From the above coordinates:
a = 7 length units,
b = 4 length units and
h = 5 length units.
Therefore, We get;
The approximate area = [(7 + 4)/2]5
= 27.5 square units
Thus, The area of the irregular shape is,
⇒ 27.5 square units

mr.brown can type 80 words in two minutes. how many words can he type in 40 minutes?
Answer:
1600
Step-by-step explanation:
We can setup a ratio in terms of words per minute.
Mr. Brown can type 80 words in 2 minutes, so our ratio looks like this:
40:2
In order to find how many words he can type in 40 minutes, we must set the minutes side of our ratio to 40. In order to do that, we must multiply our minutes side by a factor that makes it equal 40, and then multiply the words side by the same factor. We can divide 40 by 2 to figure out the factor, which is 20. Since the factor is 20, we must multiply it by the words side to figure out how many words he types in 40 minutes, which is 20 · 80 = 1600 words.

Complete the ordered pairs, using the given equation:
4x + 3y = 12 (0, ) (-1, ) ( ,10 )
Answer:
(0, 4) (-1, 16/ 3) (-9/ 2, 10)Step-by-step explanation:
In an ordered pair the term before the comma is the x variable and the term after the comma is the y variable.
1.
4x + 3y = 12 . . . . . .(0, _)
here were given the x variable
finding the other term
4× 0 + 3y = 12
3y = 12
y = 4
therefore the ordered pair is (0, 4)
2.
. . . . . . . (-1, _)
here were given the x variable
4 × -1 + 3y = 12
3y = 12 + 4
3y = 16
y = 16/ 3
ordered pair is (-1, 16/ 3)
3.
. . . . . . . . (_, 10)
here were given the y variable
finding the other term
4x + 3 × 10 = 12
4x + 30 = 12
4x = 12 - 30
4x = -18
dividing both sides by 2
2x = -9
x = -9/ 2
ordered pair is (-9/ 2, 10)

The equation of the line that goes through the point .............................................................
Answers:
m = 3/4b = -3/4Note: 3/4 = 0.75
====================================================
Explanation:
The first thing we need to do is solve that given equation for y
4x+3y = 3
3y = 3-4x
3y = -4x+3
y = (-4x+3)/3
y = (-4x)/3 + 3/3
y = (-4/3)x + 1
This last equation is in slope intercept form, y = mx+b, where,
m = -4/3 = slopeb = 1 = y interceptThese m and b values are not the final answer unfortunately, as we have yet to determine anything about the perpendicular line. However, it helps us build toward the answer.
We'll focus on the slope.
Apply the negative reciprocal to -4/3 to get 3/4. We flip the fraction and the sign from negative to positive.
This means the perpendicular slope is 3/4 and this value goes in the first box.
-----------------------------
From here, we'll use the fact that the perpendicular line goes through the point (x,y) = (5,3)
i.e. we have x = 5 and y = 3 pair up together.
Use that perpendicular slope we found earlier to say,
y = mx+b
3 = (3/4)*5 + b
3 = 15/4 + b
3 - 15/4 = b
12/4 - 15/4 = b
(12-15)/4 = b
-3/4 = b
b = -3/4 is the y intercept of the perpendicular line
Answer:
y = 3/4 x -3
Step-by-step explanation:
4 x + 3y = 3
3y = -4x + 3
y = -4/3x + 1
~~~~~~~~~~~~~~~~~~~~~~~
y = 3/4 x + b
3 = 3/4(5) + b
12 = 15 + b
B = -3

Answer:
hey mate i don't think your question is complete anyways here is what i found and i hope it is useful .
Step-by-step explanation:
(if the below is the diagram then this might help.)
In the given triangle ABC shown in the figure ∠ABC = ∠ACB
Since angles are equal so opposite sides of equal angles will be equal.
Now mAB = mAC
By putting values in terms of x
2x = 3x - 7
x = 7
Now mAC = 3x - 7
By putting value of x = 7
mAC = 3×7 - 7 = 21 - 7 = 14
Therefore length of line segment AC is 14 units.

Answer:
y = (√x/2) ± 2
Step-by-step explanation:
Here, we want to get the inverse of the given function
y = 2x^2 - 8
make x the subject of the formula
y + 8 = 2x^2
Divide through by 2
y/2 + 4 = x^2
x = √y/2 ± 2
Now switch place for x and y
y = (√x/2) ± 2

Answer:
3.5
Step-by-step explanation:
From the graph,
x1 = 0
x2 = 4
y1 = 0
y2 = 14
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope
= ( 14 - 0 ) / ( 4 - 0 )
= 14 / 4
= 7 / 2
= 3.5
Answer:
7/2
Step-by-step explanation:
the slope of a line is the ratio of y/x.
it describes how many units y changes, when x changes a defined number of units.
an increase is indicated by "+", and a decrease by "-".
the point with full integer/natural numbers as coordinates is (4, 14).
that means that when coming from point 0 (0, 0) x increases by 4 units, and y increases by 14 units.
so, the slope of line is 14/4 = 7/2

Answer:
6. A 5c + 3e + 2
7. A w = P/2 - 125
8. D point S
Step-by-step explanation:
6.
3 triangles + 5 hexagons + 2 squares =
= 3e + 5c + 2(1)
= 5c + 3e + 2
7.
perimeter = P
length = 250 m
width = w
P = 2L + 2W
P = 2(250) + 2w
2w = P - 500
w = (1/2)(P - 500)
w = (P - 500)/2
w = P/2 - 250
Incorrect expression: w = P/2 - 125

Which choice shows the coordinates of C' if the trapezoid is reflected across the y-axis?
Answer:
(-5, 3)
Step-by-step explanation:
a car can complete a journey of 300 km with a speed of 60 km per hour I) how much does it take the to complete the journey and what is the speed of the car if it covers only 200 km in the same interval of time
Step-by-step explanation:
First step:
Distance = 300km
Speed = 60km/hr
We know,
Using Speed = Distance ÷ Time
Time = Distance ÷ Speed
we have Total Time = 300÷60
Total Time = 5hr
Again,
Distance = 200km. (Time = 5hr,
Speed =? Distance = 200)
Speed = Distance÷ Time
= 200÷5
= 40km/hr

two football tickets and one basketball ticket cost $126.77. one football ticket and 2 basketball tickets cost $128.86 find the cost of each ticket
Answer:
Cost of each football ticket=$41.56
Cost of each basketball ticket=$43.56
Step-by-step explanation:
Let
Cost of each football ticket=x
Cost of each basket ball ticket=y
According to question
[tex]2x+y=126.77[/tex]...(1)
[tex]x+2y=128.86[/tex] ....(2)
We have to find the cost of each ticket.
Equation (1) multiply by 2 then we get
[tex]4x+2y=253.54[/tex] .....(3)
Now, subtract equation (2) from (3)
[tex]3x=124.68[/tex]
[tex]x=124.68/3[/tex]
[tex]x=41.56[/tex]
Now, using the value of x in equation (2)
[tex]41.56+2y=128.86[/tex]
[tex]2y=128.86-41.56[/tex]
[tex]2y=87.3[/tex]
[tex]y=87.3/2=43.65[/tex]
Hence, cost of each football ticket=$41.56
Cost of each basketball ticket=$43.56
