Answer:
10.61 cm
Step-by-step explanation:
From the question,
The volume of the rectangular piece of metal = Volume of the 45 cylindrical plates.
Volume of a cuboid = 45×volume of a cylinder
lwh = 45×πr²h..................... Equation 1
Where l = length of the rectangular piece of metal, w = width of the rectangular piece of metal, h = height of the rectangular piece of metal, r = radius of the cylindrical plates, h = thickness of the cylindrical plates.
make h the subject of the equation
h = lwh/(45πr²).................... Equation 2
Given: l = 12 cm, w = 18 cm, h = 10 cm. r = 1.2 cm
Constant: π = 3.142.
Substitute these values into equation 2
h = (12×18×10)/(45×3.142×1.2²)
h = 2160/203.60
h = 10.61 cm.
Monique wants to bake a cake. She needs 2 1/8 cups of sugar, and 1 5/24 cups of flour. How many cups of ingredients will she use in all? *
Answer:
3 1/3 cups total
Step-by-step explanation:
Add together 2 1/8 cups and 1 5/24 cups. The LCD here is 24, and so we rewrite 2 1/8 cups as 2 3/24 cups.
Adding 2 3/24 cups and 1 5/24 cups, we get 3 8/24 cups,
which simplifies to 3 1/3 cups total

During an local election the ratio of teens to adults who voted was 9.3. If 732 people voted how many were teens
Answer: 549
Step-by-step explanation:
Given
The ratio of teens to adults is 9:3
The total number of people who voted is 732
let 9x be the no of teens and 3x be the no of adults such that their ratio is 9:3
So, we can write
[tex]\Rightarrow 9x+3x=732\\\Rightarrow 12x=732\\\Rightarrow x=61[/tex]
No of the teens were [tex]9x=9\times 61=549[/tex]

(3x²-21x-24)take out the highest common factor
Answer:
x = 8 or x = -1 is the answer
Step-by-step explanation:
3x² - 21x -24
divide with 3
x² - 7x - 8
Factorizing,
x² + x - 8x - 8
x(x + 1) -8 (x + 1)
(x - 8) (x + 1)
x = 8,-1

In 2010, the population of a city was 161,000. From 2010 to 2015, the population grew by 8%. From 2015 to 2020, it fell by 6.7%. To the nearest whole number, by what percent did the city grow from 2010 to 2020.
Answer:
99%
Step-by-step explanation:
2010 population = 161,000
From 2010 to 2015, the population grew by 8%.
2010 to 2015 = 161,000 + (8% of 161,000)
= 161,000 + (0.08 * 161,000)
= 161,000 + 12,880
= 173,880
2010 to 2015 = 173,880
From 2015 to 2020, it fell by 6.7%
2015 to 2020 = 173,880 - (6.7% of 173,880)
= 173,880 - (0.067 * 173,880)
= 173,880 - 11,649.96
= 162,230.04
2015 to 2020 = 162,230.04
what percent did the city grow from 2010 to 2020.
= 161,000 / 162,230.04 × 100
= 0.9924179270374 × 100
= 99.241792703743
Approximately, 99% to the nearest whole number
I NEED HELP ADAP I NEED ANSWERS IM GIVING BRAINLIST AND 10 POINTS
Answer:
if you want the area, then:
area = 35.625 in^2 or 35 5/8 in^2
if you want the perimeter, then:
perimeter = 30.05 in or 20 1/16 in
Step-by-step explanation:
area of left side triangle = 3.75(5)(0.5) = 9.375 in^2
middle rectangle = 5.5(3.75) = 20.625 in^2
right side triangle = 3(3.75)(0.5) = 5.625 in^2
total area = 35.625 in^2
right side^2 = (3.75)^2 + 3^2
right side = 4.80
perimeter = 5.5+4.8+8.5+5+6.25 = 30.05 in

Experts believe that 70% of adults in the United States believe it is more enjoyable to be married than single. An ABC News Poll in 2004 surveyed 1,501 randomly selected adults in the United States and asked if they believed it is more enjoyable to be married or single. In the survey, 1,126 people responded that it is more enjoyable to be married. Suppose another 1051 random selected U.S. adults were surveyed and asked if they believed it is more enjoyable to be married or single. The sample proportion who respond that it is more enjoyable to be married from this new sample would most likely be different from the same sample proportion from the old sample due to ___________________.
Answer:
Due to;
Sampling variability
Step-by-step explanation:
From the question, we have;
The percentage adults experts believe are convinced that it is more enjoyable to be married than single = 70%
The number of adults in the sample of the survey = 1,501 adults
The number of adults that responded that it is more enjoyable to be married than single = 1,126
According to the central limit theorem, the differences in the two samples and the small sizes of the samples compared to the population, the sample means is different from the population mean, therefore, the sample proportion that respond that it is more enjoyable to be married from the new sample will be different from the old sample due sampling variability because as the sample size is so small compared to the population, some samples can contain more of one category in the population than other samples leading to varying proportion
