Multiply 5(−37). Simplify your answer.
− -2 1/7
− 5/33
2 1/7
5/35
Answer:
A. -2 1/7Step-by-step explanation:
Given the expression 5(-3/7)
On simplifying, we have:
[tex]= 5 \times \frac{-3}{7}\\ \\= \frac{5 \times -3}{7}\\ \\= \frac{-15}{7}[/tex]
Express as a mixed fraction
[tex]= \frac{-15}{7}\\= -2 \frac{1}{7}[/tex]
Hence the correct answer is -2 1/7

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?
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.

Jada is putting a border around her rectangular garden. The garden is 12.63 meters long and 3.28 meters wide.
This image shows a rectangular garden having a length of 12.63m and width of 3.28m.
Part A
Jada estimates the perimeter of her garden by rounding the length and width to the nearest whole number. Which equation shows her estimate?
A. 10 + 5 + 10 + 5 = 30 meters
B. 12 + 3 + 12 + 3 = 30 meters
C. 13 + 3 + 13 + 3 = 32 meters
D. 13 + 4 + 13 + 4 = 34 meters
Part B
Jada also estimates the perimeter of her garden by rounding the length and width to the nearest tenth. Which equation shows this estimate?
A. 12.6 + 3.2 + 12.6 + 3.2 = 31.6 meters
B. 12.6 + 3.3 + 12.6 + 3.3 = 31.8 meters
C. 12.5 + 3.5 + 12.5 + 3.5 = 32 meters
D. 12.7 + 3.3 + 12.7 + 3.3 = 32 meters
Part C
What is the exact perimeter of Jada’s garden? Enter your answer in the box.
meters
Part D
Select words or numbers from the drop-down menus to explain which estimate is closer to the exact perimeter.
The numbers rounded to the nearest
Choose...
are closer because
Choose...
is closer to the exact perimeter than
Choose...
.
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.

Farmer Janet can plant 9 feet of carrots in 15 minutes while her daughter Amy can plant 17 feet of carrots in half an hour. what is each persons unit rate of feet of carrots per hour
Answer:
janet can plant 36 per hour Amy can plant 34per hour
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

In each of the four relations below, the x values represent inputs and the y values represent the corresponding outputs. Which relation does not represent a function? * A) { (-2, -3), (1, 3), (3, -3), (5, 3) } B) { (-1, -5), (2, 4), (3, 7), (4, 10) } C) { (-2, 3), (1, 3), (3, 3), (5, 3) } D) { (3, 4), (4, 5), (3, -4), (4, -5) }
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.

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✨
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

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.
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
In a video game, players form teams and work together to earn as many points as possible for their team. Each team can have between 2 and 4 players. Each player can score up to 20 points in each round of the game. Han and three of his friends decided to form a team and play a round. Match each expression or inequality to the quantity that it represents.
Answer:
20 times 4
Step-by-step explanation:
Han's team has 4 players.
A perfect score is the maximum possible score. Each player can score up to 20 points in each round, so 20 points is the maximum score.
If each of the 4 players scores 20 points, then the total score for the team is:
20 *4
That is the expression for the team's points.
Answer: 20*4

Write 25/60 and 8/20 as fractions in simplest form. Then determine whether the ratios form a proportion
Answer:
8/20= 4/5
25/60= 5/12
Step-by-step explanation:
8÷4
Answer:
25/60 = 5/12
8/20 = 2/5
The Ratios do not form a proportion
Step-by-step explanation:
25/60:
25 ÷ 5/60 ÷ 5
= 5/12
8/20:
8 ÷ 4/20 ÷ 4
= 2/5
5/12 ≠ 2/5
The ratios are not proportional.

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
