Answer:
A. [tex]Ratio = 3:1[/tex]
B. [tex]Ratio= 9:3[/tex]
Step-by-step explanation:
Given
[tex]Ratio= 27:9[/tex]
Required
Determine equivalent ratios:
[tex]Ratio= 27:9[/tex]
First, we simplify the ratio to the least possible
[tex]Ratio = 27/9:9/9[/tex]
[tex]Ratio = 3:1[/tex]
By comparison with the given options, we have A and B as answer.
See Proof Below
Proof: A
Compare this to the simplified ratio (given), we have:
[tex]Ratio = 3:1[/tex] = [tex]Ratio = 3:1[/tex]
Proof B
[tex]Ratio= 9:3[/tex]
Simplify the ratio to the least possible
[tex]Ratio= 9/3:3/3[/tex]
[tex]Ratio= 3:1[/tex]
Compare this to the simplified ratio (given), we have:
[tex]Ratio = 3:1[/tex] = [tex]Ratio = 3:1[/tex]

Use the number line below, where RS=9y+2, ST=2y+6, and RT= 52
Answer:
Step-by-step explanation:
Given
RS=9y+2, ST=2y+6, and RT= 52
The addition postulate is true for the number line.
RS+ST = RT
Substitute
9y+2+(2y+6) = 52
9y+2y+8 = 52
11y = 52-8
11y = 44
y = 44/11
y = 4
Find RS
RS = 9y+2
RS = 9(4)+2
RS = 36+2
RS = 38
Find ST:
ST = 2y+6
ST = 2(4)+6
ST = 8+6
ST = 14
Hence y = 4, RS = 38 and ST = 14
Simon bought three plants at a nursery for 17.94 how hutch money would it cost for Simon to go back to the store and buy two more plants. Please help me !
Answer:
11-96
Step-by-step explanation:
The money required for Simon to buy two more plants is 11.96
What is Average?
The average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Given data ,
Number of plants Simon bought = 3 plants
Total amount of plants = 17.94
Amount for one plant = Total amount of plants / Number of plants bought
So , Amount for one plant = 17.94 / 3
= 5.98
Therefore , Amount of cost for Simon to buy two more plants = Amount of one plant x 5.98
= 5.98 x 2
= 11.96
Hence , The money required for Simon to buy two more plants is 11.96

The science teacher gives daily homework. For a random sample of days throughout the year, the median number of problems is 5 and the IQR is 2. The Spanish teacher also gives daily homework. For a random sample of days throughout the year, the median number of problems is 10 and the IQR is 1. If you estimate the median number of science homework problems to be 5 and the median number of Spanish problems to be 10, which is more likely to be accurate? Explain your reasoning.
Answer:
SCIENCE SEEMS MORE ACCURATE
Step-by-step explanation:
The interquartile range (IQR) = difference between the upper and lower quartile (Q3 - Q1)
The median can be estimated as :
(Q3 - IQR/2) or (Q1 + IQR/2).
FOR SCIENCE:
MEDIAN NUMBER = 5
IQR = 2
IQR = Q3 - Q1
Q3 = median + IQR/ 2 = 5 + 2/2 = 6
Q1 = median - IQR/2 = 5 - 2/2 = 4
FOR SPANISH:
MEDIAN = 10
IQR = 1
IQR = Q3 - Q1
Q3 = median + IQR/ 2 = 10 + 1/2 = 10.5
Q1 = median - IQR/2 = 10 - 1/2 = 9.5
Science has a lower median score and an interquartile range which is reasonable wider than Spanish with a larger median value (but a very narrow interquartile range).

Langston has 45 greeting cards. He gives 18 of the cards to his friend what present of his greeting card he does give to his friend
Answer:
it is 8.1
Step-by-step explanation:
Turn the 18 in to a percent first and then divide and it will turn into a decimal sorry im not to good at explaining so basically the answer is 18%
Langston gives his friend 40 % of his greeting card
The calculation can be done as follows
Langston has a total of 45 greeting cards
He gives his friends 18 cards
= 18/45
= 0.4 × 100
= 40%
Hence the percent of greeting cards he gives to his friend is 40%

Evaluate using order of operation and please show work
Answer:
10
Step-by-step explanation:
Given expression:
20 - [tex]\frac{15 + 3(5)^{2} }{5^{2} - 4^{2} }[/tex]
To solve this problem, we use the order of operation:
P - Parentheses
E - exponents
M - multiplication
D - division
A - Addition
S - Subtraction
Now solve the parentheses first;
= 20 - [tex]\frac{15 + 3x 25}{5^{2} - 4^{2} }[/tex]
= 20 - [tex]\frac{15 + 75}{5^{2} - 4^{2} }[/tex]
Now solve the exponents:
= 20 - [tex]\frac{15 + 75}{25 - 16}[/tex]
Now solve the division:
= 20 - [tex]\frac{90}{9}[/tex]
= 20 - 10
= 10

Need an answer and a work pls!
Answer:
t=12
Step-by-step explanation:
Step 1: Subtract t from both sides.
−t+5−t=t−19−t
−2t+5=−19
Step 2: Subtract 5 from both sides.
−2t+5−5=−19−5
−2t=−24
Step 3: Divide both sides by -2.

In which pair do both decimals represent rational numbers?
O A. 0.752 and 0.232323...
OB. 8.3182706837521... and 0.752
O C. 4.32891789376287184... and 0.2323
O D. 8.3182706837521... and 0.232323...
Answer:
A. 0.752 and 0.232323...
Step-by-step explanation:
A rational number is a number that can be expressed as a ratio. That is, it can be written as a quotient of two integers. A rational number can have a terminating decimal. E.g. 0.5, which can be expressed as ½ or 1:2. This is a terminating decimal. Also, a rational number could be a number that has repeating decimal that keeps repeating forever. E.g. 0.333... which can be expressed as ⅓, or 1:3.
An irrational number is just the opposite of a rational number. Thus, am irrational number cannot be expressed as ratio, and also has a decimal that goes on forever without repeating. For example, π = 22/7 = 3.14159... it has no definite ratio.
From these explanation we can easily pick out which pair that has both decimals representing rational numbers.
Thus, the answer is A. 0.752 and 0.232323...
0.752 is a terminating decimal, therefore it is a rational number.
0.232323... is a non-terminating decimal, however, its decimal is a repeating decimal. Therefore, it is a rational number.
Answer:
The answer is A 0.725 and 0.232323...
