Answer:
B They are similar, but not congruent.
Step-by-step explanation:
Reflection, rotation, and translation are "rigid" transformations. They result in congruent figures.
Dilation is not a rigid transformation. For any dilation scale factor other than 1, the figures will be different sizes, so will not be congruent. They will be similar. (Angles will be congruent, and lines/sides will be parallel.)
The combination of dilation (by 0.5) and reflection results in similar, but not congruent, figures.
The diameter of a wheel on a car is 16 inches. What is the circumference of the wheel? Use 3.14 for pi.
Answer:
The circumference is 50.24in.
Step-by-step explanation:
All you have to do is multiply the diameter by 3.14. Easy and so simple
The circumference of the given wheel is 50.24 inches.
What is the Circumference of a circle?The Circumference of a circle is defined as the product of the diameter of the circle and pi.
C = πd
where 'd' is the diameter of the circle
We have been given data as follows:
The diameter of the circle (d) = 16 cm
Circumference of the circle = πd
Substitute the values in the above formula and we get
Circumference of the circle = 3.14 × (16)
Apply the multiplication operation, and we get
Circumference of the circle = 50.24
Thus, the circumference of the given wheel is 50.24 inches.

Answer: 8, 2 1/6, 50, 90, 7
Step-by-step explanation:
1. Average speed = Distance/Time taken for entire trip
(10 * 3 + 2 * 1)/(3+1) = 32/4 = 8 mph
2. 6 1/4 = 25/4 9 3/8 = 75/8 (75/8)/(25/4) = 3/2
x = 3/2 + 2/3 = 13/6 = 2 1/6
3. Let's say there are x quarters in the collection, there would be 3x nickels, 2x dimes, and x quarters in the collection. The collection would be worth
3x * 5 + 2x * 10 + x * 25 = 300 cents
Solve for x to get x = 50 so there are 50 quarters in the collection
4. Sam has drove 2 * 45 = 90 miles so he has 90 miles remaining. Let's say he has to drive x hours to make his average speed 60 mph, we can use this equation to find how long he has to drive
(90+90)/(x+2) = 60 and x = 1
He has to drive 90 miles/1 hour = 90mph to make his average speed 60 mph.
5. Let's say you have to run x mph to satisfy the requirements, we can use the equation
(1.5*3+0.5*x)/(1.5+0.5) = 4 and x = 7 so you have to run 7 mph in the next 0.5 hours to satisfy the requirements
There are 1,000 meters in 1 kilometer. How many kilometers are in 3,600 meters?
HELP
Answer:
A. 3.6 kilometers
Step-by-step explanation:
1000 meters = 1 km
3600 meters = x km
Set as a ratio:
1000 : 1 = 3600 : x
Then divide:
[tex]\frac{3600}{1000} = \frac{x}{1} = x[/tex]
so 3600/1000 = 3.6 = x
3.6 km
Solve the system of equations using the linear combination method.

178-3y=3
Enter your answers in the boxes.
X
Y
Answer: x = -3; y = -8
Step-by-step explanation:
Multiply second equation by -1 and add to first equation. The y term zeros out, leaving you with -3x = 9, so x = -3.
Then go back and sub -3 in for x in either equation, and solve for y. If you use the first equation, you get 4(-3) -3y = 12
-12 -3y = 12
-3y = 24
y = -8
Hi! My question is..
What is the value of x?
A. 20
B. 40
C. 45
D. 85
Thank you.
Answer:
B. 40
Step-by-step explanation:
We know that the large angle is 90 degrees as it is a right angle. Thus, [tex]10+2x=90[/tex] (I don't know how to include degree symbols). We solve: [tex]2x=80[/tex], so then [tex]x=40[/tex]. Thus, x is forty degrees and the answer is B.
Answer:
40
Step-by-step explanation:
There is a bisector splitting a 90-degree angle into 2 parts, we are given that one of them is 10. This can only mean the other side is 80 degrees in total.
and 80/2 is 40

Faye can sort 150 recyclable items in 3 minutes Based on the ratio shown how many recyclable items can Faye sort in 4 minutes?
Answer:
200 recyclable items
Step-by-step explanation:
The computation of the number of recyclable items would be sort in 4 minutes is shown below:
Given that
There is 150 recyclable items in 3 minutes
So in 4 minutes, the no of recyclable items is
= 150 × 4 ÷ 3
= 200 recyclable items

Irene needs a total of $250 to buy a bicycle. She has already saved $70. If she saves $10 a
week from her earnings, what is the least number of weeks she must work to have enough
money to buy the bicycle?
Answer:
18 weeks
Step-by-step explanation:
250 - 70 = 180
180/10 = 18 weeks
Answer:
18 Weeks
Step-by-step explanation:
The least amount of weeks that Irene must work in order to buy the bike is 18. To find your answer, subtract $70 from $250. You will get $180. This is the amount of money that Irene still needs to earn. If she saves her money for 18 weeks, she will have her $180. This is because $180 divided by $10 is 18.

Answer: sure why not
Step-by-step explanation:
If a² + b² = c², then which of the following are also true? Select all that apply
Options
a² - b² = c²
b² + a² = c²
c² + a² = b²
c² - a² = b²
c² - b² = a²
Answer:
Option 2 , 4 & 5 are true.
Step-by-step explanation:
● Option 2 is equivalent to a² + b² = c².
● Option 4 & 5 can be found by :-
Substracting a² from both the L.H.S. & R.H.S. (It will match with Option 4)Or substracting b² from both the L.H.S & R.H.S. (It will match with Option 5)How do I simplify this
Answer:
96/18
Step-by-step explanation:
To simplify you need to turn it into an improper fraction. This means that the numerator (the number on top) is greater than the denominator (the number on the bottom). The improper fraction form of 5 6/18 is 96/18. I believe this is the answer to your question.

The systolic blood pressure of adults in the USA is nearly normally distributed with a mean of 122 and standard deviation of 22 . Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher. a. Around what percentage of adults in the USA have stage 2 high blood pressure
Answer: 4.27% of adults in the USA have stage 2 high blood pressure.
Step-by-step explanation:
Let x be a random variable that denotes a person with high blood pressure .
Given: Average blood pressure: [tex]\mu=122[/tex]
Standard deviation: [tex]\sigma=22[/tex]
Someone qualifies as having Stage 2 high blood pressure if their systolic blood pressure is 160 or higher.
The probability that an adult in the USA have stage 2 high blood pressure:
[tex]P(x\geq160)=P(\dfrac{x-\mu}{\sigma}}\geq\dfrac{160-122}{22})\\\\=P(z\geq1.72)\ \ \ [z=\dfrac{x-\mu}{\sigma}]\\\\=1-P(z<1.72)\\\\=1-0.9573\ \ [By\ p-value\ table]\\\\=0.0427=4.27\%[/tex]
Hence, 4.27% of adults in the USA have stage 2 high blood pressure.

If Θ is between 0° and 90° and tanθ = 7/8 find cosθ
Since 0° < θ < 90°, you know that cos(θ) > 0.
Recall that
1 + tan²(θ) = sec²(θ)
and also that
sec(θ) = 1/cos(θ)
So if cos(θ) > 0, we also have 1/cos(θ) = sec(θ) > 0.
Then
sec(θ) = + √(1 + tan²(θ))
sec(θ) = √(1 + (7/8)²)
sec(θ) = √113 / 8
so that
cos(θ) = 1 / (√113 / 8) = 8 / √113
