Answer:
yes
Step-by-step explanation:
(1:2)x2=9/18
yes the ratios 9:18 and 1:2 equivalent
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
We need to check whether the ratios 9:18 and 1:2 are equivalent.
Equivalent ratios are the ratios that are the same when we compare them.
Two or more ratios can be compared with each other to check whether they are equivalent or not.
Here the two ratios are 9:18 and 1:2
We can write 9:18 as fraction 9/18
When we simplify it we get 1/2
Hence, yes the ratios 9:18 and 1:2 equivalent

Find the value of\xx, y.y, and zz in the parallelogram below.
Answer:
Step-by-step explanation:
The value of x, y, and z in the parallelogram are, - 40, - 60 and 1 respectively.
What is a parallelogram?A basic quadrilateral with two sets of parallel sides is known as a parallelogram.
The opposing or confronting sides are of equal length and the sum of the adjacent angles is of equal measure.
From the given diagram,
(- 3x - 3)° + 63° = 180°.
- 3x - 3° + 63° = 180°.
x = - 40.
Similarly,
(- 3x - 3)° + (- y + 3°) = 180°.
-3(-40) - 3° - y + 3° = 180°.
y = - 60.
And,
(- y + 3°) + (z - 4°) = 180°.
180° + 3° + z - 4° = 180°.
z = 1.

expressions to match it.
a 2(x+4)
6. 8+2x
c. 2x+4
d. 3(x+4)+(4 + x)
ex+4
Answer:
a and b are equivalent.
c, d and e are not equivalent.
So, 2 equivalent expression for c and are,
c.
( i ) 2 ( x + 2 )
( ii ) ( 4x + 8 ) / 2
d.
( i ) 3x + 16
( ii ) ( 6x + 32 ) / 2
Step-by-step explanation:
a.
2 ( x + 4 )
= 2 ( x ) + 2 ( 4 )
= 2x + 8
b.
8 + 2x can also be written as 2x + 8.
d.
3 ( x + 4 ) + ( 4 + x )
= 3 ( x ) + 3 ( 4 ) + 4 + x
= 3x + 12 + 4
= 3x + 16

students?
01/21
01/11
11/1
21/1
Answer:
1:21
The reason why is because adding 11 and 10 you get 21 and there is only one coach so you would get 1:21
can someone answer these questions?
Answer:
the first question is 80 yards
Step-by-step explanation:
the reason why is because it is a square it has all equal sides, a square has 4 sides so it would be 4 times 20 which equals 80. Hope that helps

if y²-x=7, find the positive value of when x=9.
Answer:
y = + 4
Step-by-step explanation:
y² - x = 7 ← substitute x = 9 into the equation
y² - 9 = 7 ( add 9 to both sides )
y² = 16 ( take square root of both sides )
y = ± [tex]\sqrt{16}[/tex] = ± 4
the positive value of y when x = 9 is + 4
Answer:
4
Step-by-step explanation:
when x = 9:
⇒ y² - 9 = 7
⇒ y² = 7 + 9
⇒ y² = 16
⇒ y = √16
⇒ y = ±4
Therefore, the positive value of y = 4
Find the perimeter simple
20 points and brainliest
Answer:
62, the person in the comments helped me notice it was not as simple as it seemed.
The formula for finding perimeter is add all sides.[tex]23 + 6 = 29[/tex] « First two lengths
[tex]8 + 9 = 17[/tex] « Second lengths
[tex]23 - 9 = 14missing[/tex] « The missing length which was difficult for me
[tex]17 + 29 + 14 + 2 = 62[/tex] « Adding all lengths combined
Hope this helps. Let me know if it's right this time.
Answer:
62
Step-by-step explanation:
Ok so we have all but two identified lengths, but we can find them pretty quickly. To find the horizontal unidentified length, we can write 23-9=14 and get out length. To find the vertical length we can write 8-6=2 to get the length. Now add all lengths together 23+8+9+2+14+6=62 to get the perimeter. Just putting it here for the points :)

when a number was divide by 12 the quotient was 52 and the reminder was 5 what was the number
Answer:
???
Step-by-step explanation:
1. 52 + 5 = 57
2. 57 × 12 = 684
3. Test it out
684 ÷ 12 = 57
which is wrong because of the remainder.
BUT the remainder is not possible because 12 was the number it was divided by and 12 can not go into 5
so either your question is wrong or my solution is wrong
At a gymnastics meet, three judges evaluate the balance beam performances of five gymnasts, using a scale from 1 to 10, where 10 is a perfect score. A statistician wants to see if the gymnasts (Factor A) differ in their performances and also wants to see if the scores vary significantly across judges (Factor B) in order to assess any bias in the judges. To do this the statistician uses a two-way ANOVA without interaction and the results are show below. At 0.05 level of significance, what is the critical value for testing differences in mean scores across the Gymnasts
Answer:
As 2.551 < 3.84 therefore we reject H0.
As 44.803 > 4.46 so we accept null hypothesis.
Step-by-step explanation:
The answer is attached.
There are three judges so v1 = 3-1= 2 and v2 = (4*2)= 8
There are five gymnasts so v1 = 5-1= 4 and v2= (4*2)= 8
For alpha = 0.05 we find the value of F1 and F2 from the table.

Answer:
1. x=25
2. x=6
Step-by-step explanation:
1. The angles of a triangle have to add up to equal 180 degrees so 180 minus 130 equals 50 and the two and that are unknown are the same so 50 divided by 2 equals 25
2. It is an isosceles triangle so the two sides are the same and if you plug in 6 for x you get the other missing side of the triangle as 24 as well.

16.3x42.7+22.5x16.3 = 1062.76 (approximately 1063)
Answer:
1063 cm^2
Step-by-step explanation:
notice you have 4 triangles. Take advantage of that!
the formula for a triangle:
[tex]\frac{base * height}{2}[/tex]
the triangles on the left side are the same so
2 * ([tex]\frac{42.7 * 16.3}{2}[/tex]) = 696.01 cm^2
I multiplied it by 2 because there are two corresponding triangles.
on the right side it's the same:
2 * [tex]\frac{22.5 * 16.3}{2}[/tex] = 366.75 cm^2
Now add those values: 696.01 + 366.75 = 1,062.76 cm^2
make sure you round to the nearest square centimetre: then the answer is 1063 cm^2.
You could also use the area of a rhombus.

Dudley Durite deposited $350 into a savings account that earns 6.5% interest compounded semi-annually. What amount was in his account at the end of 1-year?
Answer:
$373.12
Step-by-step explanation:
You want to set this up with the equation for compound interest which is [tex]A=P(1+\frac{r}{n})}^{nt}[/tex]. A stands for amount, P stands for principle which in this case is 350, r is rate which for this one is .065, ad n is the amount of times compounded per year, and since it is compounded semi annually you do 2 for 2 times a year. Your equation based on this information should look like this:
[tex]A=350(1+\frac{.065}{2})}^{(2)(1)}[/tex]
After working this out you get A = 373.12
$373.12

A coordinate plane is shown. Angle XYZ has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees.
Angle XYZ is rotated 270 degrees counterclockwise about the origin to form angle X’Y’Z’. Which statement shows the measure of angle X’Y’Z’?
m∠X’Y’Z’ = m∠XYZ
m∠X’Y’Z’ = 180 degrees
m∠X’Y’Z’ = 270 degrees
