Answers
Answer/Step-by-step explanation:
Length of rectangular garden = 12.63 m
Width of rectangular garden = 3.28
Part A: Perimeter of garden if the length and height is rounded to nearest whole number.
12.63 rounded to nearest whole number = 13
3.28 rounded to nearest whole number = 3
Equation that shows her estimate would be: C. 13 + 3 + 13 + 3 = 32 meters
Part B: Perimeter of garden if the length and height is rounded to nearest tenth.
12.63 rounded to nearest tenth = 12.6
3.28 rounded to nearest tenth = 3.3
Equation that shows this estimate would be: B. 12.6 + 3.3 + 12.6 + 3.3 = 31.8 meters
Part C: Exact Perimeter of her garden.
Exact perimeter would be 12.63 + 3.28 + 12.63 + 3.28 = 31.82 meters
Part D:
Difference between 31.82 and the exact perimeter is 0.02, while difference between 32 and the exact perimeter is 0.18.
Therefore:
The numbers rounded to the nearest TENTH are closer because 31.8 meters is closer to the exact perimeter than 32 meters.
There are 10 lanes in the bowling alley where Harold bowls. He wants to make a
scale drawing of the bowling alley using a scale of 3 cm to 15 ft. One lane,
including gutters, is 60 ft long and 5 ft wide. What will the width of all 10 lanes on
his drawing be?
please help this is urgent!! provide good for explanation✨
Answers
Answer:
10cmStep-by-step explanation:
Given that the scale of the drawing is 3 cm to 15 ft.
This means that, every 15ft in the drawing will be represented by 3cm.
also there are a total of 10 lanes
given that the width of one lane is 5ft, the ten will be 5*10= 50ft
Now how many 15ft are there in 50ft= 50/15= 3.33
now in cm = 3.33*3=10cm
therefore on the drawing the width will be 10cm

Answers
Answer:
[tex]\boxed {a_{24} = 145}[/tex]
Step-by-step explanation:
According to the following pattern sequence ([tex]7, 13, 19, 25[/tex] ), it is Arithmetic Sequence, because every number is added by [tex]6[/tex]. So, to find the 24th term, you need to use the Arithmetic Sequence Formula and solve to find the 24th term:
[tex]a_{n} = a_{1} + (n - 1) d[/tex]
[tex]a_{n}[/tex]: nth term in the sequence
[tex]a_{1}[/tex]: 1st term
[tex]n[/tex]: term position
[tex]d[/tex]: Common difference
-Apply to the formula:
[tex]a_{24} = 7 + 6 (24 - 1)[/tex]
[tex]a_{n} = a_{24}[/tex]
[tex]a_{1} = 7[/tex]
[tex]n = 24[/tex]
[tex]d = 6[/tex]
-Solve:
[tex]a_{24} = 7 + 6 (24 - 1)[/tex]
[tex]a_{24} = 7 + 6 (23)[/tex]
[tex]a_{24} = 7 + 138[/tex]
[tex]\boxed {a_{24} = 145}[/tex]
Therefore, the 24th term is [tex]145[/tex].
The 24th term of the sequence is 145
7, 13 , 19, 25
The sequence is an arithmetic progression. Therefore, let's use arithmetic progression formula for nth term to find the 24th term.
Arithmetic progression:aₙ = a + (n - 1)dwhere
a = first term
d = common difference
n = number of term
Therefore,
d = 13 - 7 = 6
a = 7
a₂₄ = 7 + (24 - 1)6
a₂₄ = 7 + (23)6
a₂₄ = 7 + 138
a₂₄ = 145
Therefore, the 24th term of the sequence is 145

Step-by-step explanation:
Answer:
Janet's is 36 feet of carrots per hour
Amy is 34 feet of carrots per hour
Step-by-step explanation:
for Janet I did 60÷15=4(thqt is one hour) then 9×4=36 which is the answer
for Amy I did 17×2=34 because she does 17 in 40 mins which is half an hour so you would double to make it one hour

You hang two strings of decorative lights. Strand 1: changes between red and blue every 15 seconds. Strand 2: changes between green and gold every 18 seconds. Both strands just changed color. After how many seconds will the strands change color at the same time again?
Answers
Answer:
The strands change color at the same time again after 90 seconds
Step-by-step explanation:
We are told:
Strand 1: changes between red and blue every 15 seconds.
Strand 2: changes between green and gold every 18 seconds.
To solve for this question, we use the LCM method.
Step 1
List multiples of each number until the first common multiple is found.
Multiples of 15:
15, 30, 45, 60, 75, 90, 105, 120
Multiples of 18:
18, 36, 54, 72, 90, 108, 126
Therefore,
LCM(15, 18) = 90
The first common multiple is 90, and this is the lowest common multiple.
Therefore, the strands will change color at the same time again after 90 seconds.

Given:
In each of the four relations below, the x values represent inputs and the y values represent the corresponding outputs.
To find:
The relation which does not represent a function.
Solution:
A relation is a function if there exist a unique output for each input.
In options A, B and C, we get unique output for each input.
In option D, we get two outputs y=4 and y=-4 for input x=3.
Since, there exist more than one output values for a single input value, therefore it is not a function.
Therefore, the correct option is D.
Sofia and Manuel are purchasing a home. They wish to save money for 15 years and purchase a house that has a value of $200,000 with cash. If they deposit money into an account paying 5% interest, how much do they need to deposit each month in order to make the purchase? Round your answer to the nearest cent, if necessary.
Answers
Answer:
Monthly deposit= $745.76
Step-by-step explanation:
Giving the following information:
Future Value (FV)= $200,000
Number of periods= 15*12= 180 months
Interest rate= 0.05/12= 0.0042
To calculate the monthly deposit, we need to use the following formula:
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (200,000*0.0042) / [(1.0042^180) - 1]
A= $745.76
