Step-by-step explanation:
First off, we can rotate it. When rotating, I found that the x and y values switch places in a way.
We would need to rotate it 90 degrees counterclockwise about the origin in order to get it in the same position as triangle BDE. This makes statement B correct.
In order to make triangle ABC smaller, the dilation would have to be smaller than one. Counting the right side's length, ABC has 6 squares and BDE has 3.
This would mean 6 * 1/2 = 3, meaning statement D is true.

Work out the value of x.
Answers
Answer:
The value of x is 67.5
Step-by-step explanation:
The sum of the measures of the angles around a point is 360°
Let us solve the question
∵ In the given figure there are 3 adjacent angles around one vertex
→ By using the rule above
∴ The sum of their measures is 360°
∵ One of the angles is a right angle
∵ The measure of the right angle is 90°
∵ The measures of them are x, 3x, and 90°
∴ x + 3x + 90° = 360°
→ Solve the equation by adding the like terms to find x
∵ (x + 3x) + 90 = 360
∴ 4x + 90 = 360
→ Subtract 90 from both sides
∵ 4x + 90 - 90 = 360 - 90
∴ 4x = 270
→ Divide both sides by 4
∴ x = 67.5
∴ The value of x is 67.5

Answer:
x1=-5/2, x2=1
Step-by-step explanation:
Answer:
x1=-5/2, x2=1
Step-by-step explanation:
because if you use quadratic formula
you would have x = -3 + or - √3^2 -4 x 2 x (-5)/ 2 x 2
simply and combine like terms give you
x = -3 + 7 / 4
x = -3 - 7 / 4
then you get
x = 1
x = -5/2
oil is leaking out of a tank. the depth of oil in the tank for 60 seconds is shown below. use the graph to work out the rate of decrease of depth, in cm/s, at 10 seconds. you must show your working.
Answers
Answer:
2.24
Step-by-step explanation:
The rate of decrease at 10 seconds is - 0.642.
What is the formula for exponential growth and exponential decaying function?The formula for exponential growth is y = y₀.e^(kt).
The formula for exponential decay is y = y₀.e^(-kt).
From the graph, we conclude that it is an exponentially decaying function.
At t = 10, depth = 60 and at t = 0 depth = 112
(as every box represents 4 units).
So, the rate of decrease can be obtained by,
112 = 60.e^(-10k).
e^(-10k) = 1.86.
lne^(-10k) = ln1.86.
- 10k = 6.42.
k = - 0.642.
The rate of decrease at 10 seconds is - 0.642.

A gardener plans to extend the length of a rectangular garden. Let x represent the garden's original length. The expression 4(x+7) represents the area of the extended garden. WHen asked for the area of the extended portion the gardener incorrectly said it was 11 square feet. Describe the error the gardener made.
Answers
Answer:
The answer is "[tex]4 \cdot 7[/tex]".
Step-by-step explanation:
In the question the total given value =4(x+7). if we add the value it will be 11 but if we multiply the value it is equal to [tex]4 \cdot 7[/tex].
The error gardener made is that the area of the extended portion is 28 ft² instead of 11 ft².
Given to us
The original length of the garden is x.
The Area of the extended garden is 4(x+7).
Area of the Extended GardenGiven to us is the area of the complete garden, therefore, comparing the expression with the area of a rectangle,
[tex]\text{Area of rectangle}= \rm{ Breadth \times Length[/tex]
[tex]4(x+7) = Breadth \times Length[/tex]
Therefore, the breadth of the rectangle is 4 feet, since the breadth of the rectangle is not been changed the breadth of the rectangle is same as before, also (x+7) represents the complete length of the garden after it is extended, and since the original length of the garden is x, the length extended is 7 feet.
Area of the only Extended Portion of the GardenWe know that the breadth of the rectangular garden is 4 and the area of extended length is 7, therefore,
The Area of the only Extended Portion of the Garden
= 4 x 7 = 28 ft²
Hence, the error gardener made is that the area of the extended portion is 28 ft² instead of 11 ft².

Kane is trading for a marathon he starts running 3 miles during every training season each week plans to increase the distance of his run by 1/4 mile . Let w be the number of weeks write and expression to show the distance Kane runs in a training session after w weeks
Answers
Answer:
(11+w)/4
Step-by-step explanation:
Let the first term be 3 miles
If he plans to increase the distance of his run by 1/4 mile, then
common difference = 1/4
To get the distance Kane runs in a training session after w weeks , we will use the nth term of an AP
Tw = a+(w-1)d
Tw = 3 + (w-1)(1/4)
Tw = 3 + 1/4 w - 1/4
Tw = 11/4 + 1/4 w
Tw = (11+w)/4
Hence the distance Kane runs in a training session after w weeks is (11+w)/4 weeks

Kristen is making accessories for the soccer team. She uses 595.56 inches of fabric on headbands for 39 players and 3 coaches. She also uses 343.59 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answers
Answer:
22.99 inches
Step-by-step explanation:
According to problem, given data are as follows:
Fabric used for headband = 595.56 inches
Number of headbands made = 39 + 3 = 42
So, Fabric used per headband = 595.56 ÷ 42 = 14.18 inches per headband
Similarly, Fabric used for wristband = 343.59 inches
Number of wristbands made = 39
So, Fabric used per wristband = 343.59 ÷ 39 = 8.81 inches per wristband
So, Fabric used for each player = 14.18 inches + 8.81 inches
= 22.99 inches
Stephen's watch loses time. Stephen set his watch to the correct time at 10 a.M., but noticed three hours later that it read 12:54. If Stephen does not adjust his watch, at what time on his watch should he show up at the restaurant for a 7 o' clock date with Mabel?
Answers
Answer:
6:54
Step-by-step explanation:
Correct time set = 10 am
Correct time after 3 hours = 10 am + 3 hours
= 1 pm
Steven watch after 3 hours = 12:54
This means Steven watch is 6 minutes behind the normal time
If Stephen does not adjust his watch, at what time on his watch should he show up at the restaurant for a 7 o' clock date with Mabel?
Time Stephen show up for date with Mabel = 7:00 - 6 minutes
= 6:54
