Answer:
Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units
the perimeter is 194.6 units
1. Change the standard form equation into slope intercept form, then name the slope and the y- intercept.
2x-3y=12
2. What is the slope of the line represented by the equation
Y=(2/3)x-4?
A. 4
B. 2/3
C. -4
D. -2/3
Answers
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x - 3y = 12 ( subtract 2x from both sides )
- 3y = - 2x + 12 ( divide all terms by - 3 )
y = \(\frac{2}{3}\) x - 4 ← in slope- intercept form
with slope m = \(\frac{2}{3}\) and y- intercept c = - 4
2
The line y = \(\frac{2}{3}\) x - 4
has slope m = \(\frac{2}{3}\) → B
Answer:
11.slope intercept form:
y=2/3x-4
2. slope;
2/3
Step-by-step explanation:
1. make y the subject
2. =mx+c
m is the slope therefore 2/3 is the slope

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

For a randomly selected driver, are the events "driving while using a cell phone" and "having a traffic accident" independent events? Explain your answer. PLEASE HELP :(
Answers
Answer:
Let's denote:
The event of driving while using a cell phone: A
The event of having a traffic accident: B
The event of driving while using a cell phone and having a traffic accident: A⋂B
P(A) = 11% = 0.11
P(B) = 5.26% = 0.526
P(A⋂B) = 28% = 0.28
If event A and event B are independent (it means the cause of a traffic accident is nothing related to driving while using a cell phone), then:
P(A) x P(B) = P(A⋂B)
Let's check:
P(A) x P(B) = 0.11 x 0.526 = 0.05786 and not equal to P(A⋂B) = 0.28
=> Event A and event B are not independent. In other words, they are related. (it means driving while using a cell phone is one of the reasons for having a traffic accident)

Write equivalent expressions to the following expressions by either expanding or factoring.
-4(2w-5z)
6ab-12bc-3bd
Answers
Answer:
Step-by-step explanation:
1) -4(2w - 5z): We are going to expand this term by distributing -4 to both 2w, and -5z. To do this, multiply -4 by each of these terms. (-4 * 2w) = -8w and (-4 * -5z) = 20z. So, your final answer is -8w + 20z, or 20z -8w(both are equal).
2) Take out the GCF to factor the equation. In this case, the GCF would be 3b. Divide 3b by each of the existing terms. 6ab/ 3b = 2a; -12bc/3b = -4c; -3bd/3b = -d. Put those terms together and you get 3b(2a - 4c - d). Hope this helps! If not, feel free to ask additional questions.

parabola y = -6x=2 and x=6Greatest value of y is y=2 and it occurs when x = 4For x between x = 2 and x = 6, y > 0Step-by-step explanation:
Definition
A parabola is a curve where any point is at an equal distance from:a fixed point (the focus ), and
a fixed straight line (the directrix )
From the graph we can see that this is indeed so. We can even calculate the parabola equation from the given graph but since that is not required, I am not illustrating the steps here to do that
The y-intercept is the value of y where the parabola cuts the y axis and from the graph we see that this occurs at y = -6The x-intercepts are the x-values where the parabola crosses the x-axis and we can see that this occurs at x = 2 and x = 6The greatest value of y occurs at the vertex of the parabola and we see that the vertex is at (4,2) ie greatest value of y is at y = 2 and occurs at x=4Between x =2 and x = 6 we see that the y values greater than 0 ie y > 0(Note on last question: If you exclude these two points then y > 0 between x=2 and x=6.Specifically it is 0 at x =2 and x=6 and > 0. So if you include these two points then y ≥ 0. I have taken it as excluding the two points, x = 2 and x =6)

Jason wants to plant 66 carrot seeds and 44 onion bulbs. He would like to plant them so
that there are the same number of plants in each row and each row only has one type of plant. a. What is the greatest number of plants he can have in each row? SHOW YOUR
WORK
Answers
Answer:
Step-by-step explanation:
Since we need an equal amount plants in each row, you have to find the greatest common factor (GCF) of 66 and 44.
The factors of 44 are: 1, 2, 4, 11, 22, 44
The factors of 66 are: 1, 2, 3, 6, 11, 22, 33, 66
Therefore, the greatest factor of 66 and 44 is 22. This means Jason will have 3 rows of carrot plants and 2 rows of onion plants. Each row will have 22 plants.
Jason can have a maximum of 22 plants in each row. This allows him to place 22 onion bulbs or 22 carrot seeds in each row.
We need to determine the greatest common divisor (GCD) of 66 and 44 to determine the maximum number of plants Jason can have in each row while still adhering to the requirements of having the same number of plants in each row and each row having only one type of plant.
The GCD denotes the maximum number of plants he is permitted to place in each row.
Using the Euclidean algorithm to find the GCD:
1. Divide the larger number by the smaller number:
66 ÷ 44 = 1 with a remainder of 22.
2. Divide the smaller number 44 by the remainder 22: 44 ÷ 22 = 2 with no remainder.
3. Since there is no remainder, the GCD is the divisor in the last division, which is 22.

Answer:
y = -180 + 3x
Step-by-step explanation:
Because AB = AC -> ABC is a isosceles triangle -> B = C
Because AB = BD -> ABD is an isosceles triangle -> A = D -> x = D
We have ADB + ADC = 180 -> x + ADC = 180 -> ADC = 180 - x (1)
We have x = D, and BAD + ADB + ABD = 180 -> ABD = 180 - 2x but B = C -> C = 180 - 2x (2)
With (1) and (2) We have DAC + ACD + ADC = 180
-> y + 180 -2x + 180 -x = 180
-> y + 360 - 3x = 180

Maxwell invested a total of $100,000. He invested his money in three different accounts. He invested $35,000 at 10% annual interest rate, $42,000 at 8% annual rate, and the remainder at 14% interest rate. How much interest did Maxwell receive in one year?
Answers
Step-by-step explanation:
Sure! Here's the step-by-step calculation:
1. Calculate the interest earned on the first investment:
$35,000 * 10% = $3,500
2. Calculate the interest earned on the second investment:
$42,000 * 8% = $3,360
3. Calculate the amount invested in the third account:
Total investment - (First investment + Second investment)
$100,000 - ($35,000 + $42,000) = $23,000
4. Calculate the interest earned on the third investment:
$23,000 * 14% = $3,220
5. Add up the interest earned from all three investments:
$3,500 + $3,360 + $3,220 = $10,080
Therefore, Maxwell received $10,080 in interest in one year.
