What is the height of a solid cylinder with a mass of 26.05 g, a diameter of 3.56 cm, and a density of 2.72 g/cm^3?
Answer:
h = 0.962 cm
Step-by-step explanation:
Given that,
Mass of a solid cylinder, m = 26.05 g
The diameter of a cylinder, D = 3.56 cm
Radius, r = 1.78 cm
The density of a cylinder is 2.72 g/cm³
We need to find the height of the cylinder. Let it is h. We know that mass per unit volume is equal to density of an object. It can be given by :
[tex]d=\dfrac{m}{V}\\\\d=\dfrac{m}{\pi r^2 h}\\\\h=\dfrac{26.05}{\pi \times (1.78)^2\times 2.72}\\\\h=0.962\ cm[/tex]
So, the height of the cylinder is 0.962 cm.

Chen recorded the number of texts he sent and the number of tweets he posted each day for a month. The equation y = 5x + 4,
where x is the number of texts and y is the number of tweets, models the relationship between these two quantities. Identify the
slope and explain its meaning within this context.
Answer/Step-by-step explanation:
The relationship between number of texts, x, and number of tweets, y, is represented in the slope-intercept form by the equation, y = 5x + 4.
The slope of this equation is 5.
In this context, the slope, 5, means 5 tweets are made for every 1 text sent each day.
This slope is positive meaning, as text sent increases, also, tweets increased.

There are 8 more girls than boys in a school play. The ratio of boys to girls is 5:7. How many boys and how many girls are in the play?
Answer:
The total number of boys and girls in the play is 48
Step-by-step explanation:
Don't ask how I know this, I just do.
The number of boys in school play will be 20 and number of girls in school play will be 28.
What do you mean by ratio ?
Ratio is the quantitative relationship between two values indicating how frequently one value contains or is contained within the other.
It is given that number of girls is 8 more than boys in a school play.
Ratio of boys to girls = 5 : 7
Let's assume the total number of boys in school play is x.
This meant the total number of girls in school play is :
= x + 8
We can write them in proportion form as :
x : x + 8 = 5 : 7
or solving it we get :
[tex]\frac{x}{x+8}[/tex] = [tex]\frac{5}{7}[/tex]
or
7x = 5(x+8)
7x = 5x + 40
7x - 5x = 40
2x = 40
x = 20
or number of boys in school play is 20.
So , number of girls in school play will be :
= 20 + 8
= 28
Therefore , the number of boys in school play will be 20 and number of girls in school play will be 28.

Could anyone help with “b” on the bottom. I’m not sure what it’s asking. Thank you!!
Answer:
yes
Step-by-step explanation:
the question is asking if the mean helped you find the number that pops up the most, so in this case 3.
by using the mean we will do
0+0+3+3+5+7+2+2+3+3+3+5 divided by 12
giving us a result of 3, in this case YES it does help at better explaining the typical value

1. In a box full of different fruit 30% of them are apples. If there are 15 apples in
the box, how many total pieces of fruit are in the box?
Your answer
Answer:
50
Step-by-step explanation:
15/x=30/100
30x=1500
x=50
there are 50 apples in the box.
part/whole = percent/100
15/x = 30/100
30x = 1500
x = 50

tea drinkers in Canada is 4:1. Jack concluded from this that if 400 people
were surveyed, 100 of them would most likely be regular tea drinkers. Is
he correct? Explain.
Answer: He is incorrect.
Step-by-step explanation:
The question says:
"tea drinkers in Canada is 4:1"
We only have that, so i guess that this means:
"The ratio of nonregular tea drinkers to regular tea drinkers in Canada is 4:1"
The ratio 4:1 means that for each 4 non-regular tea drinkers, there is one regular tea drinker.
Now let's multiply both by 100.
For each 400 nonregular tea drinker, there are 100 regular tea drinkers, if we add them we have a total of 500
Then the statement would be if 500 people were surveyed, 100 of the would most likely be regular tea drinkers.
The number of different simple random samples of size 5 that can be selected from a population of size 8 is
Answer:
Number of different simple random samples of size 5 that can be selected from a population of size 8 = 56 ways
Step-by-step explanation:
Step 1: Stating the combination formula
The number of selections of a number n, taking r at a time is given by the formula: [tex]\frac{n!}{(n - r!)r!}[/tex]
From the formula above, n is population size = 8
r is sample size = 5
Step 2: Substituting the values of n and r
Number of possible selections = 8!/(8 -5)*5! = 8!/3! * 5!
Number of possible selections = [tex]\frac{8*7*6*5*4*3*2*1}{3*2*1 * 5*4*3*2*1}[/tex]
Number of possible selections = 56
Therefore, number of different simple random samples of size 5 that can be selected from a population of size 8 = 56 ways

Step-by-step explanation:
If A=(-1, -3) and B=(11,-8), what is the length of AB?
A. 14 units
B. 13 units
C. 12 units
D. 11 units
9514 1404 393
Answer:
B. 13 units
Step-by-step explanation:
The distance formula can be useful.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((11-(-1))² +(-8-(-3))²) = √(12² +(-5)²) = √(144 +25) = √169
d = 13
The length of AB is 13 units.

If you're familiar with a few of the small Pythagorean triples, you would know that for integer coordinates, an integer answer is most likely to be 13. The x- and y-differences in coordinates being 12 and 5 confirm that the (5, 12, 13) triple is being used here.
There are no Pythagorean triples with hypotenuse values of 11, 12, or 14. (3, 4, 5) can be doubled to give (6, 8, 10), but 10 is not a choice.

325 x 454 ≈ __________ x __________ = 150,000
can somone help me with this one
Answer: 300 x 500=150,000
Step-by-step explanation: Here, they're asking you to create a ballpark estimate by rounding. Since most people can't multiply 325 by 454 in their heads, it's more ideal to simply round to get an estimate first. Here, the numbers are rounded to the nearest hundred for a more friendly equation. The ≈ sign means approximately equals, or about, which indicates that your answer is close but not exact.
