Answer:
Option. B is not describing the a rigid transformation.
Step-by-step explanation:
Rigid transformation means an object when moved from one point to another, its position may change but size and shape of the object remains unchanged.
By this definition,
Option A. translating a figure 4 units up
In this statement only place is moving not the size, so it's Correct (describing rigid transformation)
Option B. Enlarging a figure by a scale factor of 2.
In this option size of the object is enlarged by a scale scale factor of 2, so this option is Not correct (not describing rigid transformation)
Option C. Rotating a figure by 180°
Again place is changing so its describing the rigid transformation. Correct (describing rigid transformation).
Option D. Reflecting a figure across the y axis.
Reflection means change in place. So the option is Correct (describing rigid transformation).
Suppose f(x)=2x−5. Find the value of f(3)
can someone please help me with this?
f(3) = 1
substitute x = 3 into f(x)
f(3) = (2 × 3) - 5 = 6 - 5 = 1
To find the value of f(3) for the function f(x) = 2x - 5, substitute x = 3 into the function. The value of f(3) is 1.
Explanation:To find the value of f(3) for the function f(x) = 2x - 5, we substitute x = 3 into the function.
So, f(3) = 2(3) - 5.
Simplifying further, we get f(3) = 6 - 5 = 1.

The volume of a cube is length × breadth× height
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions. Operators which let do a basic mathematical calculation
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Given that,
Volume of a box = 15,552 cubic feet
Since one foot is equal to twelve inches.
We are to convert the dimension to cubic feet.
Using the conversion factor
∵ 1 feet = 12 inches
∴ 1 cubic foot = 1728 cubic inches
Divide 15,552 by 1728
⇒ 15,552/1728
⇒ 9
Hence, the volume of the box is 9 cubic feet.

Which of the following is a true statement describing the pattern 20, 25, 30, 35,…? The pattern contains only even numbers. The pattern contains only odd numbers. The pattern is decreasing. The pattern contains only factors of 5.
In this pattern all are divisible by 5
20[tex] =4×5[/tex] i.e. divisible by 5
25[tex] = 5×5 [/tex] is divisible by 5
30[tex] =2×3×5[/tex] is divisible by 5
35[tex] =7×5 [/tex] is divisible by 5
Hence the pattern contain factor 5
The statement that correctly describes the pattern 20, 25, 30, 35, ... is that it contains only factors of 5.
The given sequence of numbers is 20, 25, 30, 35,... and the correct statement describing this pattern is that it contains only factors of 5. This is because each number in the sequence is a multiple of 5 and can be divided by 5 without leaving a remainder. The sequence is not exclusively even or odd numbers, as it contains both (20 and 30 are even, while 25 and 35 are odd). Also, the pattern is not decreasing; it is instead increasing by increments of 5.

Tickets to a concert cost $2 for children, $3 for teenagers and $5 for adults. When 570 people attended the concert, the total ticket receipts were $1950. Three-fourths as many teenagers as children attended. How many adults attended?
Answer: 220
Step-by-step explanation:
Children (x): $2
Teens (y): $3, [tex]\frac{3}{4}x[/tex]
Adults: (z): $5
Quantity: x + y + z = 570 ⇒ x + [tex]\frac{3}{4}x[/tex] + z = 570 ⇒ 1.75x + z = 570
Cost: 2x + 3y + 5z = 1950 ⇒ 2x + 3[tex](\frac{3}{4}x)[/tex] + 5z = 1950 ⇒ 2x + 2.25x + 5z = 1950 ⇒ 4.25x + 5z = 1950
Qty: 1.75x + z = 570 → 5(1.75x + z = 570) → 8.75x + 5z = 2850
Cost: 4.25x + 5z = 1950 → -1(4.25x + 5z = 1950 → -4.25x - 5z = -1950
4.50x = 900
x = 200
Teens (y): [tex]\frac{3}{4}x[/tex]
y = [tex]\frac{3}{4}(200)[/tex]
= [tex]\frac{600}{4}[/tex]
= 150
Quantity: x + y + z = 570
200 + 150 + z = 570
350 + z = 570
z = 220

Mr. Hodges wants to build a fence around his entire rectangular garden. What is the total distance around the garden?
30 feet with 6 yards
Answer:
The total distance around the garden is 96 feet.
Step-by-step explanation:
We are given a rectangular garden which is 30 feet by 6 yards.
In order to solve this problem, first we have get our units right. We decide to work with feet.
1 yard = 3 feet.
Therefore,
6 yard = 18 feet.
Thus, in feet we have a rectangular garden which is 30 feet by 18 feet.
Therefore the total distance around the garden—i.e its perimeter—is:

what is 6 7/8 + 7 5/12
[tex]6 \: \frac{7}{8} \: + 7 \frac{5}{12} [/tex]
Here is your equation:
[tex]6 \frac{7}{8} + 7 \frac{5}{12}[/tex]
As you can see, the denominators, which is the bottom number in the fraction, are different. You need to have the same denominator, so that you can add it. To change the denominators, you need to find the LCM of both denominators, which is 8 and 12. To find the LCM, first list the multiples of both numbers and see what is common.
[tex]8 - 8, 16, 24, 32, 40, 48, 56 \\12-12, 24, 36, 48[/tex]
The only common number is 48. That means you need to change both fractions so that they have a denominator of 48.
[tex]6 \frac{7 \times 6}{8 \times 6} \rightarrow 6 \frac{49}{48}[/tex]
[tex]7 \frac{5 \times 4}{12 \times 4} \rightarrow 7 \frac{20}{48}[/tex]
Here is your new equation:
[tex]6 \frac{49}{56} + 7 \frac{20}{48}[/tex]
Add:
[tex]6 \frac{49}{48} + 7 \frac{20}{48} = 13 \frac{69}{48}[/tex]
Simplify:
[tex]13 \frac{69}{48} \rightarrow 14 \frac{21}{48} \rightarrow 14 \frac{7}{16}[/tex]

Rewriting the equation by factoring 4 from 28, factoring out x², and factoring out y²We then can rewrite 4 as 2² in our equation, leaving us with [tex]\sqrt{2^{2}*7*(x^{2}x)*y^{2}y }[/tex]We will then move our x and 7, and rewrite [tex]2^{2}*x^{2}* y^{2}[/tex] as [tex](2xy)^{2}[/tex]We can then pull the terms from the radical leaving us with [tex]2xy\sqrt{7xy}[/tex]78 = -2(m + 3) + m. 0.6(y + 3) = 4.8
Given: ABC is similar to XYC. If BY = 4, YC = 7, XC = 10. Which of the following proportions could be used to solve for AC? 4/7 = 10/AC 7/4 = 10/AC 4/11 = 10/AC 7/11 = 10/AC
Answer: The correct option is 4th, i.e., [tex]\frac{7}{11}= \frac{10}{AC}[/tex].
Explanation:
It is given that ABC is similar to XYC. If BY = 4, YC = 7, XC = 10.
Draw a diagram by using the given information.
From the figure,
[tex]BC=BY+YC[/tex]
[tex]BC=4+7[/tex]
[tex]BC=11[/tex]
If the two triangles are similar then their corresponding sides are is in proportion and the corresponding angle are same.
[tex]\frac{YC}{BC}=\frac{XC}{AC}[/tex]
[tex]\frac{7}{11}=\frac{10}{AC}[/tex]
Therefore, the correct option is 4th.

The number of yellow fish at the aquarium is 5 fewer than 3 times the number of blue fish. The table shows how the number of yellow fish, y, depends on the number of blue fish, b. Choose the equation which represents the rule.
Answer:
If you are on USATestPrep (which you most likely are) the correct answer is C.
Step-by-step explanation:
C) y = 3b − 5
It is “5 fewer than 3 times”
Answer:
y = 3b-5
Step-by-step explanation:
The number of yellow fish is 5 fewer than 3 times the number of blue fish. Using b to represent the number of blue fish, 3 times this is 3b; 5 fewer than this is 3b-5. This gives us the equation
y = 3b-5

35 rounded to the nearest hundred
Answer and Explanation: 35 rounded to the nearest 100 is 0. To round to the nearest hundred, you need to first identify the hundreds that are closest to the number you are rounding. For 35, the closest hundred that is lower than 35 is 0, and the closest 100 that is higher than 35 is 100.
The rounding of 35 to the nearest hundred gives us 0.
To round 35 to the nearest hundred, we need to determine which hundred it's closest to. In this case, we can see that 35 is near to 0 than to 100.
When rounding to the nearest hundred, we look at the number in the knock outs place.
However, we round up, and if it's lower than 5, If it's 5 or lesser.
In the number 35, the knockouts number is 3.
Since 3 is lower than 5, we round down.
When we round down, we keep the hundreds number as is and replace all the integers to the right with bottoms.
Thus, rounding 35 to the nearest hundred gives us 0.
