P.S I TRIED MY BEST
Step-by-step explanation:
The required values of ratios are 9/16,3/2, 7/6 and 1/12 respectively. The only false option is (c).
What is the application ratio and proportion?A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.
Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.
All the options are examined one by one as follows,
(a) The ratio of 5/8 to 10/9 is given as,
5/8 : 10/9
= (5/8) ÷ (10/9)
= 5/8 × 9/10
= 9/16
Thus, it is true.
(b) The ratio of 4/7 ∶ 8/21 is given as,
4/7 ∶ 8/21
= (4/7) ÷ (8/21)
= 4/7 × 21/8
= 3/2
Thus, it is true.
(c) The unit rate of 7/9 and 2/3 equivalent to the ratio given below,
7/9 : 2/3
= 7/9 ÷ 2/3
= 7/9 × 3/2
= 7/6
Thus, it is false.
(d) The unit rate of 9/16 and 27/4 equivalent to the ratio given below,
9/16 : 27/4
= 9/16 ÷ 27/4
= 9/16 × 4/27
= 1/12
Thus, it is true.
Hence, the ratios for the given options are obtained as 9/16,3/2, 7/6 and 1/12 respectively.

9
Answer:Group of answer choices
Step-by-step explanation:
What you first want to do is like and unlike terms so basically liketerms are terms withthe same sign and unlike terms are terms with diferent signs for instinse 3g and 2g are like terms so -33 and -9 and -9 and 9 are unlike terms so you just have to find the like and unlike terms to answer the question!
Answer: -9
Step-by-step explanation: Let's solve your equation step-by-step.
3g+15−12+3−2g+4=1
Step 1: Simplify both sides of the equation.
3g+15−12+3−2g+4=1
3g+15+−12+3+−2g+4=1
(3g+−2g)+(15+−12+3+4)=1 (Combine Like Terms)
g+10=1
g+10=1
Step 2: Subtract 10 from both sides.
g+10−10=1−10
g=−9
So the answer is g=-9

1. For a party, Susan estimated there would be 14 people in attendance, but only 12 showed up. What was the percent error in her estimation?
2. Find the percent error in this situation:
Estimated value: 231
Actual value: 215
3. Find the percent error in this situation:
Experimental value: 16.5 sec
Theoretical value: 17.1 sec
4. Find the percent error in this situation:
Estimated value: 1081
Actual value: 1150
The formula for percent error is:
((Approximate value - exact value) / exact value) x 100
1) 14-12 = 2
2/12 = 0.1666
0.166 x 100 = 16.7% (Rounded to nearest tenth)
2) 231 - 215 = 16
16/215 = 0.74419
0.74419 x 100 = 7.4419% ( Round as needed)
3) 17.1 - 16.5 = 0.6
0.6/16.5 = 0.36364
0.36364 x 100 = 3.6364% (Round off as needed)
4) 1081 - 1150 = -69
-69/1150 = -0.06
-0.06 x 100 = -6% = 6% error
Answer:
1) 85.7%
2) 93%
3) 96.5%
4) 94%

the answer its c 122 is angle 1
Answer:
A. 32
Step-by-step explanation:
The two angles are equal to each other so you can set them equal and solve
2x+57=6x-71
Add 71 to both sides
2x+57+71=6x+0
2x+128=6x
Subtract 2x from both sides
128=6x-2x
128=4x
Divide 4 from both sides
128/4=x

solve the equation 1/4t - 6 = -4
Answer:
t = 8
Step-by-step explanation:
[tex]\frac{1}{4}t - 6 = -4\\ +6 \\^{*4} \frac{1}{4}t = 2^{*4} \\t = 8[/tex]
The value of t in the given expression is t = 8
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given is an expression we need to simplify it for t,
The expression is 1/4t - 6 = -4
So, add 6 to both sides,
1/4 t -6 + 6 = -4 + 6
1/4 t = 2
Multiply by 4 to each side,
1/4 x 4 t = 2 x 4
t = 8
Hence, the value of t in the expression given is 8

Step-by-step explanation:
Following the previous question, how much does the video game cost after taking 30% off? (Subtract total cost and money saved)
Answer:
Well for example most video games cost $60, so if you divide the original price by 100 and multiply it by 30, you'll get 18, so you take away that from 60, then you'll get 42.
Step-by-step explanation:
60 divided by 100 = 0.6, times that by 30 = 18, take away that from the original price which was 60, you'll get 42.
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
If the cost of the video game is $60
The cost of the video game after 30% off is $42
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
We will assume that the cost of the video game = $60
Percentage off = 30%
30% = 30/100
30% of 60 = 30/100 x 60 = 18
The cost after 30% off.
= $60 - 30% of $60
= 60 - 30/100 x 60
= 60 - 18
= $42
Thus,
If the cost of the video game is $60
The cost of the video game after 30% off is $42

Daniel has a collection of stamps worth $6. He has 5 more 8 cent stamps then 30 cent stamps. The number of 6 cent stamps is 2 times the amount of 30 cent stamps. The number of 5 cent stamps is 12. How many of each kind of stamps does Daniel have?
Please list the number of 30, 5, 6, 8 cent stamps he has.
First gets Brainliest!!!
Answer:
12 of the 5 cents stamps,
20 of the 6 cents stamps
15 of the 8 cents stamps
10 of the 30 cents stamps.
Step-by-step explanation:
Let's name:
x = number of 5 cent stamps,
w = number of 6 cent stamps,
y = number of 8 cent stamps,
z = number of 30 cent stamps,
Create the following system of equations based on the info provided:
z + 5 = y
w = 2 * z
x = 12
600 = 5 (12) + 6 w + 8 y + 30 z
replace everything in terms of "z":
600 = 60 + 6 (2 * z) + 8 (z + 5) + 30 z
540 = 12 z + 8 z + 40 + 30 z
500 = 50 z
z = 10
and now we can find the rest:
y = 5 + 10 = 15
w = 2 * 10 = 20
Therefore there are:
12 of the 5 cents stamps,
20 of the 6 cents stamps
15 of the 8 cents stamps
10 of the 30 cents stamps.
