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
Lindsey’s cookie recipe uses 1 1/2 cups of brown sugar to make 2 dozen cookies. Lexi wants to make only 1 dozen cookies. How much brown sugar should Lexi use?
Answer:
3/4 cups
Step-by-step explanation:
Answer:
1.5 cups
Step-by-step explanation:
144 cookies divided by 24 cookies is 6. This means that we will be making 6 batches of 24 cookies. We will then multiply 1/4 by 6, which means that we will need 1.5 cups of brown sugar for 144 cookies.

Part A: To draw triangles ABC and DEC separately, follow these steps:
Draw a line segment DE with a length of 1.2 feet. This will be the base of both triangles.At point D, draw a perpendicular line segment DC with a length of 2 feet. This will be the height of triangle DEC.At point E, draw a line segment EB with a length of 0.3 feet. This will be the height of triangle ABC.Connect points C and B with line segment BC. This will be the hypotenuse of both triangles.What is the others about?The lengths of sides BC, DE, and EC are as follows:
BC: It is the hypotenuse of triangle ABC and has a length that needs to be calculated using the Pythagorean theorem.DE: It is the base of both triangles and has a length of 1.2 feet.EC: It is the height of triangle DEC and has a length of 2 feet.Part B: To find side AB of triangle ABC, we can use the concept of similarity and ratios. Since triangles ABC and DEC are similar, their corresponding sides are proportional. We can set up the following proportion:
AB/DE = BC/EC
Plugging in the given values, we get:
AB/1.2 = BC/2
To solve for AB, we can cross-multiply and then divide:
AB = (BC/2) x 1.2
Now we need to find the value of BC. We can use the Pythagorean theorem, as BC is the hypotenuse of triangle ABC. The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
BC² = AB² + BE²
Plugging in the given value for BE, we get:
BC^2 = AB² + 0.3²
Now we can substitute the value of AB from the previous equation into this equation:
BC² = ((BC/2) * 1.2)² + 0.3²
Simplifying, we get:
BC² = 0.36 x BC^2/4 + 0.09
Multiplying both sides by 4 to eliminate the fraction, we get:
4 x BC² = 0.36 x BC² + 0.36 + 0.09
Combining like terms, we get:
4 x BC² = 0.36 BC² + 0.45
Subtracting 0.36 x BC² and 0.45 from both sides, we get:
3.64 x BC² = 0.45
Dividing both sides by 3.64 to isolate BC², we get:
BC² = 0.45 / 3.64
Taking the square root of both sides to solve for BC, we get:
BC ≈ √(0.45 / 3.64)
BC ≈ 0.357 feet
Now we can substitute the value of BC back into the equation for AB:
AB = (BC/2) x 1.2
AB ≈ (0.357/2) x 1.2
AB ≈ 0.214 feet
So, the approximate length of side AB of triangle ABC is 0.214 feet.

Answer:
1/32
Step-by-step explanation:
The probability of rolling a 6 on a 6-sided die is 1/6, and the probability of rolling a 4 on a 6-sided die is also 1/6.
Assuming that the rolls are independent (i.e., the outcome of one roll does not affect the outcome of the other roll), the probability of rolling a 6 and then a 4 is the product of the probabilities of each individual event:
Probability of rolling a 6 and then a 4 = (Probability of rolling a 6) x (Probability of rolling a 4)
= (1/6) x (1/6)
= 1/36
Therefore, the probability of rolling a 6 and then a 4 on a 6-sided die rolled twice is 1/36, or approximately 0.0278 (2.78%).

Two trains, Train A and Train B, weigh a total of 346 tons. Train A is heavier than Train B. The difference of their weights is 238 tons. What is the weight of each train?
Answer:
A=292, B=64
Step-by-step explanation:
A+B=346 equ 1
A>B
A-B=238 equ 2
A=238+B
input into equ 1
238+B+B=346
238+2B=346
collect like terms
2B=346-238
2B=108
divide both sides by 2
B=54
A=238+B
A=238+54
A=292

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides

Frank finds 9 coins on the floor of his car, and 3 of them are quarters. If he finds 15 more coins on the ground, at the same ratio as the coins found in the car, how many more coins will most likely be quarters?
Answer: 5 coins
Step-by-step explanation:
Frank found 9 coins on the floor of his car, and 3 of them were quarters. This means that 3 out of the 9 coins, or \(\frac{3}{9}\), were quarters.
Simplifying this fraction, we get \(\frac{1}{3}\) of the coins found in the car were quarters.
If Frank finds 15 more coins on the ground at the same ratio, then \(\bold{\frac{1}{3}}\) of these coins will also be quarters. To find out how many quarters he will most likely find, we need to find \(\bold{\frac{1}{3}}\) of 15:
\(\large \frac{1}{3} \times 15 = 5\)
Therefore, Frank will most likely find 5 more quarters on the ground, assuming he finds coins at the same ratio as he did in his car.

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

Since it's asking for the coordinate points of the post office, it would be (x, y). The x-value where the post office on the grid is 9, and the y-value where the post office on the grid is also 9, so the coordinate points will be (9,9).
