Answer:
(x, y) -> (2.5x, 2.5y)
Step-by-step explanation:
To find which equation is correct, first, let's find a similar point of Figure J and Figure K.
Figure J: (-3, -2). Figure K: (-7.5, -5)As you can see, Figure J was enlarged by a SF of 2.5 because -3 x 2.5 = -7.5, and -2 x 2.5 = -5.
Therefore, the answer is (x, y) -> (2.5x, 2.5y).
(Please help!) Find the surface area of the rectangular prism
Answer:
156.25
Step-by-step explanation:
A = 2 (wl + hl + hw)
A = 2 (5.5 x 3 + 7.25 x 3 + 7.25 x 5.5)
A = 2 (16.5 + 21.75 + 39.875)
A = 2 x 78.125
A = 156.25

What is 2.73 divided by 30
Answer:
2.73 divided by 30 is 0.091
Answer:
0.091
Step-by-step explanation:
First, let's convert 2.73 into a whole number by multiplying it by 100.
2.73 × 100 = 273.We also have to multiply 30 by 100.30 × 100 = 3000Now, we divide 273 by 3000.

7x-14=2x+11
X=?
(step by step)
Answer:
7x-14=2x+11
Step-by-step explanation:
Collect like terms
7x-2x=11+14
5x=25
Divide both sides by the coefficient of x(5).
x=25/5
x=5
Answer:
x=5
Step-by-step explanation:
The first thing we need to do in this equation is to get both of the x variables on the same side.
How do we do this you might ask? Well, need to cancel out the 2x so all we have left is one x variable. We can do this by subtracting 2x from each side.
The important thing to remember when solving equations like these is that whatever you do to one side, you MUST do to the other side.
2x-2x is 0 so that cancels out the 2x on the right side. 7x-2x=5x so we are left with that for our left side.
Now, we have to get rid of the constants (the non-variable numbers)
Let’s cancel out the 14 on the left side so the x is still by itself.
Add 14 to -14 to cancel it out. Do the same to the right side. 14+11=25 so that 25 is what we are left with on the right side.
Our equation becomes 5x=25
Now we have to completely isolate the x with no coefficient. We do this by dividing 5 by each side. But remember the rule, whatever you do to one side, you must do to the other. So we divide 25 by 5 as well.
5x/5 is x and 25 divided by 5 is 5
So our final answer is…
X=5

Steven has a bag of 20 pieces of candy. Five are bubble gum, 8 are chocolates, 2 are fruit chews, and the rest are peppermints. If he draws one piece of candy what is the probability that it will be chocolate?
Answer:

Step-by-step explanation:
This answer is 8/20 because they’re only 8 chocolates in the whole bag. So it is the amount you have over the total.
1. since A^2= 36x^2, a=?
2. since b^2= 49, b=?
Answer:
D
Step-by-step explanation:
36x² - 49 ← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
then
36x² - 49
= (6x)² - 7²
= (6x - 7)(6x + 7)
Thus 6x - 7 is a factor of the expression
We need to simplify the expression 36x² - 49 , but let's recall the identity which is the main key to solve this question i.e
[tex]{\boxed{\bf{a^{2}-b^{2}=(a+b)(a-b)}}}[/tex]So , here we can write the above expression as
[tex]{:\implies \quad \sf (6x)^{2}-(7)^{2}}[/tex]
Now , using the above identity this can be written as :
[tex]{:\implies \quad \sf (6x-7)(6x+7)}[/tex]
So , here both (6x-7) and (6x+7) are factors of 36x²- 49 , but in the options their is only 6x - 7.
Hence , Option D) 6x - 7 is correct
As here , 36x² = (6x)² = a² , so a = 6x and as 49² = 7² = b² , so b = 7

What is the greatest common factor (GCF) of 15 and 6x?
Answer:
3
Step-by-step explanation:
Factors of 15: 1, 3, 5, 15
Factors of 6x: 1, 2, 3, 6, x
Therefore, the greatest common factor (the highest factor that they both share) is 3
Factor = f
——————
f15 = 1, 3, 5, 15
f6 = 1, 2, 3, 6, x
So the answer is 1 and 3, but we need to give the answer from the highest number. The highest number is 3.

Find the value of aBc
Compound shape
Answer:

Step-by-step explanation:
using the sine ratio in right Δ ABD
sin ABD = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AD}{AB}[/tex] = [tex]\frac{4}{8}[/tex] = [tex]\frac{1}{2}[/tex] , then
∠ ABD = [tex]sin^{-1}[/tex] ( [tex]\frac{1}{2}[/tex] ) = 30°
Using the sine ratio in right Δ CBD
sin CBD = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{CD}{BC}[/tex] = [tex]\frac{3}{3\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] , then
∠ CBD = [tex]sin^{-1}[/tex] ( [tex]\frac{1}{\sqrt{2} }[/tex] ) = 45°
Then
∠ ABC = ∠ABD + ∠ CBD = 30° + 45° = 75°

16. Suppose Eva has 12 3/4 pounds of flour. The day's baking will require triple that amount.
How much flour will Eva need?
A. 37 lb
B. 38 1/2 lb
C. 373/4 lb
D. 38 1/4 lb
E. 38 1/3 lb
Answer:
Option D
Step-by-step explanation:
Given the following question:
[tex]12 \frac{3}{4} \times3[/tex]
In order to find the answer, we have to convert the mixed number and then multiply by three, since how Eva needs triple the amount for today's baking.
[tex]12 \frac{3}{4} \times3[/tex]
[tex]12\frac{3}{4} =4\times12=48+3=51=\frac{51}{4}[/tex]
[tex]3=\frac{3}{1}[/tex]
[tex]\frac{51}{4} \times\frac{3}{1}[/tex]
[tex]51\times3=153[/tex]
[tex]4\times1=4[/tex]
[tex]=\frac{153}{4}[/tex]
Convert the improper fraction back into a mixed number:
[tex]\frac{153}{4}[/tex]
[tex]\frac{153}{4} =153\div4=38\frac{1}{4}[/tex]
[tex]=38\frac{1}{4}[/tex]
Which means Eva needs "38 1/4 pounds of flour" or option D for today's baking.

Answer:
138°
Step-by-step explanation:
X = 180° - 42° [Sum of angles in a triangle]
X = 138°
Answer: 48 degrees.
Step-by-step explanation: The key to finding a missing interior angle is to have all the angles add up to 180. The corner with the square means that the angle is 90 degrees. An angle has been provided, which is 42 degrees. Now, we can add 42 and 90, and you have 132 degrees so far. Now, we need to subtract 132 from 180 and we have 48 degrees. That is your value of x.

Find an equation for the perpendicular bisector of the line segment whose endpoints are (6,9) and (2,5).
Answer:
x + y = 11
Step-by-step explanation:
The perpendicular bisector goes through the midpoint of the segment and has a slope that is the opposite reciprocal of the slope of the segment. The midpoint is ...
M = (A+B)/2 = ((6, 9) +(2, 5))/2 = (6+2, 9+5)/2 = (8, 14)/2
M = (4, 7) = (Mx, My)
The slope can be found from the differences of the coordinates of the two points:
(Δx, Δy) = (2 -6, 5 -9) = (-4, -4)
Factoring out -4, this becomes
(Δx, Δy) = (1, 1)
__
These values can be used directly to form the equation of the perpendicular line:
(Δx)(x -Mx) +(Δy)(y -My) = 0
1(x -4) +1(y -7) = 0
x + y = 11 . . . . . . . . . add 11 and simplify
___
Additional comment
Using "standard form" for the equation, we don't actually need the value of the slope. If you were to use point-slope form or slope-intercept form for the equation of the line, then you would need to know the slope of the segment is ...
m = Δy/Δx = 1/1 = 1
and the slope of the perpendicular is ...
m' = -1/m = -1/1 = -1

In order to subtract these fractions, we should turn the first fraction into an improper fraction.
What is an improper fraction?
An improper fraction is a fraction whose numerator is greater than its denominator.
How to turn a mixed number into an improper fraction?
Multiply the whole number by the denominator.- Multiply 1 times 8
2. Add the numerator.
- Add 7 to the product of 1 and 8 (which, of course, is equal to 8)
8+7=15
Therefore, we have
[tex]\bold{\displaystyle\frac{15}{8} -\frac{3}{8}}[/tex]
Now all we have to do is subtract the numerators!
[tex]\bold{\displaystyle\frac{12}{8}}[/tex]
Surprise! This fraction can be reduced:
[tex]\boxed{\boxed{\bold{\displaystyle\frac{3}{2}}}}[/tex]
Hope everything is clear.
If you have any questions, please ask.
