Answer:
3.) 2.5cm
4.) 14mm
5.) 1.75in
6.) 12cm
7.) 4in
8.) 1.6ft
9.) 31.4in
10.) 43.96in
11.) 56.52in
Step-by-step explanation:
3-5 finding the radius is just half of the diameter.
#3
5/2= 2.5
#4
28/2= 14
#5
3.5/2= 1.75
6-8 is finding the diameter. To find the diameter multiply the radius by 2.
#6
6*2= 12
#7
2*2= 4
#8
.8*2= 1.6
9-11 is finding the circumference. To find it use this equation C= 2πr.
C= circumference, 2=2, π= 3.14, r= radius
#9 the diameter is 10in so the radius is 5in
C=2(3.14)5
C=31.4
#10 the radius is 7in
C= 2(3.14)7
C= 43.96
#11 diameter is 18in so the radius is 9in
C=2(3.14)9
C= 56.52

-13 = r/9 + 8
r =
r equals what
-5=r/9
-45=r
Step-by-step explanation:
you're just trying to get the r alone. so you have to subtract the 8 and multiply the nine. you're just reversing the problem.

Step-by-step explanation:
-6x + 3x = -21 solving for variable
x= 7 is the answer
Combine like terms
-3x=21
Divide both sides by 3
x=7
Answer:
[tex]:\implies \sf -6x + 3x = -21 \\ \\ \\ [/tex]
[tex]:\implies \sf - 3x = -21\\ \\ \\ [/tex]
[tex]:\implies \sf x = \dfrac{-21}{ - 3} \\ \\ \\ [/tex]
[tex]:\implies \sf x = \dfrac{21}{3} \\ \\ \\ [/tex]
[tex]:\implies \underline{ \boxed{ \textsf { \textbf{x = 7}}}} \\ [/tex]

(-1, 2)
(2, 2)
(1, 1)
Step-by-step explanation:
if Both rotating in the same way, then EfGH is gonna go the other way. (sorry if its wrong, i'm learning this too)

Find the distance between the two points if rounded to the nearest tenth (-6,6) and (-3,3)
Answer:
3[tex]\sqrt{2}[/tex] units
Step-by-step explanation:
Given parameters:
Coordinates = (-6,6) and (-3,3)
Unknown:
The distance between them = ?
Solution:
To find the distance between two points, we use the expression below;
D = [tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2} }[/tex]
x₁ = -6 x₂ = -3
y₁ = 6 y₂ = 3
D = [tex]\sqrt{(-3 -(-6))^{2} + (3-6)^{2} }[/tex] = [tex]\sqrt{18}[/tex]
D = 3[tex]\sqrt{2}[/tex] units

In 2001, gold was priced at (0.5x + 300) dollars per ounce. Its price tripled in 2008 and then doubled in 2011. In 2016, its price dropped to 2 3 of the price in 2011.
• Write an expression for the price of gold per ounce in 2016.
• Explain how you found the expression.
Answer:
[tex]2x + 1200[/tex]
Step-by-step explanation:
[tex].5x + 300 \\ 3(.5x + 300) = 1.5x + 900\\ 2(1.5x + 900) = 3x + 1800 \\ \frac{2}{3} (3x + 1800) = 2x + 1200[/tex]

Answer:
2/3
Step-by-step explanation:
Slope equals rise/run. You find one perfect point (-2,0) and another along the line (1,2)
You count how many units up (rise) from the first point to the second point, and then you go over (run) to the second point. Your rise over your run is your slope.

Answer:3/12 is greater
Step-by-step explanation:
Since 3/12 and 2/9 have different denominators, you need to find the Least Common Multiple (LCM) of the denominators and then multiply the top and bottom of each fraction by the number of times the denominator goes into the LCM.
According to my calculations, the LCM of the two denominators is 36. Therefore, since 12 goes into 36 a total of 3 times, you would multiply the top and bottom of the first fraction by 3. And since 9 goes into 36 a total of 4 times, you would multiply the top and bottom of the second fraction by 4.
Step #2: Now that the denominators are the same, you can simply compare the numerators to determine which fraction is greater. Since 9 is greater than 8, 9/36 is greater than 8/36. Therefore the 1st entry (3/12) is greater than the 2nd entry (2/9).

Answer to Parallelogram JKLM question:
Q = 110° & ST = 9 ft
Explanation:
When reflecting this, the angle/side lengths remain the same. That means the information is going to be the exact same. All you have to do is figure out what corresponds to what from JKLM to QTSR.
If we reflect a figure across a horizontal reflection line through its center, the figure will just flip sides. Making L = K, M = J, and so on.
Basically, flip the shape upside down for this problem, and look at that and the shape without angles, find the corresponding letter to the angle to get your answer. In this case, Q is that corresponding letter. Meaning your answer for Q = 110°
When it comes to figuring out ST, since the shape is just flipped and all the lines making the parallelogram are equal to each other, the feet remains the same. Meaning ST = 9 ft.

Find three consecutive odd integers whose sum is -45. Find the largest
integer
x = the first integer.
x + 2 = the second integer.
x + 4 = the third integer.
x + x + 2 + x + 4 = -45
Combine like terms.
3x + 6 = -45
Subtract 6 from both sides.
3x = -51
Divide both sides by 3
x = -17
x + 2 = -17 + 2 = -15
x + 4 = -17 + 4 = -13
The largest integer is -13

Answer:
The change is increased by 80%.
Step-by-step explanation:
Divide 36 by 45. This gives you 0.8. Divide 36 by 0.8 and multiply 45 by 0.8 to check your answer. So, it is increased by 80%. To find out how percents change, divide the first number by the second number. Then, take the decimal and move the decimal point over to the right two spaces, or multiply the entire number by 100.
