Answer:
The density is 1.59 g/mL. Therefore, the substance will NOT float in water.
Step-by-step explanation:
The following data were obtained from the question:
Mass of empty flask = 245.8 g
Mass of flask + CCl₄ = 444.6 g
Volume of CCl₄ = 125 mL
Density of CCl₄ =?
Next, we shall determine the mass of carbon tetrachloride, CCl₄. This can be obtained as follow:
Mass of empty flask = 245.8 g
Mass of flask + CCl₄ = 444.6 g
Mass of CCl₄ =.?
Mass of CCl₄ = (Mass of flask + CCl₄) – (Mass of empty flask)
Mass of CCl₄ = 444.6 – 245.8
Mass of CCl₄ = 198.8 g
Finally, we shall determine the density of carbon tetrachloride, CCl₄ as follow:
Mass of CCl₄ = 198.8 g
Volume of CCl₄ = 125 mL
Density of CCl₄ =?
Density = mass / volume
Density of CCl₄ = 198.8 / 125
Density of CCl₄ = 1.59 g/mL
The density of water is 1 g/mL. Since the density of carbon tetrachloride, CCl₄ (i.e 1.59 g/mL) is bigger than that of water, the substance will not float in water.
The density of carbon tetrachloride is 1.59 grams per milliliter.
Given that an empty erlenmeyer flask that weighs 245.8 g is filled with 125 mL of carbon tetrachloride, and the weight of the flask and carbon tetrachloride is found to be 444.6 g, to determine the density of carbon tetrachloride the following calculation must be performed:
Subtract the weight of the empty flask from the weight of the full flask, and then divide this result by 125 (the milliliters of carbon tetrachloride).
(444.6 - 245.8) / 125 = X 198.8 / 125 = X 1.59 = X
Therefore, the density of carbon tetrachloride is 1.59 grams per milliliter.

jdbdjdajhsbsbs
Answer:
Step-by-step explanation:
The graph has both a vertical and horizontal asymptote to which the value
of the function approaches as the y-values and x-values approaches
infinity respectively.
The horizontal asymptote is; y = 0The vertical asymptote is the line x = 1Reasons:
The horizontal asymptote is the horizontal line that the function's graph
tends towards as the value of the input variable approaches infinity.
The horizontal line that the graph of the function approaches is y = 0
Therefore;
The horizontal asymptote is; y = 0Similarly, the vertical asymptote is the vertical line that the graph of the
function approaches but never meets.
Therefore;
The graph of the function on the bottom left approaches the line x = 1 from
the left, while the graph of the function with the domain 0 < x < ∞,
approaches the line x = 1 from the right.
Therefore;

Write an equation for the line that passes through (2,5) and (6,7)
Answer:
[tex]y=\frac{1}{2}x+4[/tex]
Step-by-step explanation:
Find the slope of the line first using the slope formula:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]Substitute the two given points into this formula.
[tex]\frac{7-5}{6-2} =\frac{2}{4} =\frac{1}{2}[/tex]Now that you have a slope and a point that the line passes through, you can use the point-slope formula to find the equation of the line.
Point-slope formula:
[tex]y-y_1=m(x-x_1)[/tex]Substitute m = 1/2 for the slope and one of the points; I'm going to use (2, 5).
[tex]y-(5)=\frac{1}{2} (x-(2))[/tex]Simplify the equation so it's easier to read.
[tex]y-5=\frac{1}{2} (x-2)[/tex]Distribute 1/2 inside the parentheses.
[tex]y-5=\frac{1}{2}x-1[/tex]Add 5 both sides of the equation.
[tex]y=\frac{1}{2}x+4[/tex]Answer:
The slope is the change in y over the change in x.
(7-5) / (6-2) = 2 / 4 = 1 / 2
In y = mx + b, we know y, m, and x. Now solve for b:
Let's use the point (2, 5).
5 = (1/2)(2) + b
5= 1 + b
b = 4
Now put it together:
y = (1/2)x + 4

Lucia wishes to advertise her business, so she gives packs of 6 red flyers to each restaurant owner and sets of 4 blue flyers to each clothing store owner. At the end of the day, Lucia realizes that she gave out the same number of red and blue flyers. What is the minimum number of flyers of each color? Flyers
Answer:
12
Step-by-step explanation:
No. of red flyers = 6
No. of blue flyers = 4
We need to find the minimum number of flyers of each color if she gave out the same number of red and blue flyers. For this we must find the LCM of 6 and 4.
Prime factorization of 6 = 2×3
Prime factorization of 4 = 2×2
Lowest common multiple of 6 and 4 = 12
Hence, there are 12 minimum number of flyers of each color
Which of the following equations could represent

Answer:
A) y - 11 = -6(x - 0)
C) y + 1 = -6(x - 2)
Step-by-step explanation:
Plug in the corresponding x- and y- values in the table into the equations given in the answer choices.

A) y - 11 = -6(x - 0)[tex](5)-11=-6((1)-0)[/tex][tex]-6=-6(1)[/tex][tex]-6=-6[/tex]-6 DOES equal 6, so this equation could represent the points in the table.
B) y - 1 = -6(x + 5)[tex](5)-1=-6((1)+5)[/tex][tex]4=-6(6)[/tex][tex]4 \not=-36[/tex]4 does NOT equal 36, so this equation could not represent the points in the table.
C) y + 1 = -6(x - 2)[tex](5)+1=-6((1)-2)[/tex][tex]6=-6(-1)[/tex][tex]6=6[/tex]6 DOES equal 6, so this equation could represent the points in the table.
D) y - 7 = -6(x - 3)[tex](5)-7=-6((1)-3)[/tex][tex]-2=-6(-2)[/tex][tex]-2\not=12[/tex]-2 does NOT equal 12, so this equation could not represent the points in the table.
The only two equations that could represent the points in the table are answer choices A) y - 11 = -6(x - 0) and C) y + 1 = -6(x - 2).
What is the only real number which, when divided by itself, is 2020
times itself?
Answer:
1/2020
Step-by-step explanation:
We can set up an equation, where x is the number that, when divided by itself, is 2020 times itself:
x/x = 2020*x
The left-hand side reduces to 1:
1 = 2020*x
Now, you can divide both sides by 2020:
x = 1/2020
To check, we can divide 1/2020 by itself:
[tex]\frac{\frac{1}{2020}} {\frac{1}{2020}} = \frac{1}{2020}\cdot \frac{2020}{1} = \frac{2020}{2020} = 1[/tex]
1 is indeed 2020 times 1/2020.
We have that
x=4.95*10^{-4}
From the question we are told
What is the only real number which, when divided by itself, is 2020
times itself
Generally the equation for the statement is mathematically given as
[tex]\frac{x}{x}=2020*x\\\\1=2020*x\\\\x=\frac{1}{2020}\\\\x=4.95*10^{-4}[/tex]
Hence
the only real number which, when divided by itself, is 2020
times itself is

Para recortar algumas figuras geométricas, um aluno utilizou uma cartolina com 1mx0,8m. Sabendo que ele recortou 2 triângulos, ambos com 20cm de base e 30 cm de altura, 2 trapézios ambos com bases de 10cm e 20cm e altura de 7cm. Determine em cm² quanto foi a área da cartolina que sobrou. * 1 ponto 7595cm² 0,7595m² 7190cm² 0.719m²
Answer:
7190 cm²
Step-by-step explanation:
Para recortar algumas figuras geométricas, um aluno utilizou uma cartolina de 1 m x 0,8m.
Passo 1
Determine a área de todo o papelão
= Temos dimensões = 1mx0,8m
Área = Comprimento × Largura
= 0,8m²
Nós convertemos para cm²
1 m² = 10.000 cm²
0,8m² = x cm²
Multiplicação cruzada
0,8m² × 10.000 cm² / 1 m²
= 8000 cm²
Passo 2
Sabendo que recortou 2 triângulos, ambos com 20cm de base e 30cm de altura
Encontramos a área de um triângulo
= 1/2 × base × altura
= 1/2 × 20 × 30
= 300cm²
Ele cortou 2 triângulos Portanto, o são dos dois triângulos = 300cm² × 2
= 600cm²
etapa 3
Ele também cortou 2 trapézios ambos com bases de 10cm e 20cm e altura de 7cm.
A área de um trapézio =
1/2 (a + b) h
= 1/2 (10cm + 20cm) × 7cm
= 1/2 × 30 × 7
= 105 cm²
Ele cortou dois trapézios, portanto
A área dos dois trapézios do corte = 105cm² × 2
= 210 cm²
Passo 4
A área total do papelão que foi cortado = 600cm² + 210cm²
= 810 cm²
Etapa 5
Determine em cm² quanto de papelão sobrou.
Isso é calculado como:
Área total do papelão - Área total que foi cortada
= 8000 cm² - 810 cm²
= 7190 cm²

Nishi invests $3000 at 5% interest per year. Work out how much she will have altogether after:
Answer:
2 years: 30
5 years: 75
7 years :105
10 years:150
i think those are the answer
Step-by-step explanation:
take the interest percentage and divide by 100 ex:5.2%100= 0.052
take the dollar amount and multiply interest decimal ex:$ 450*0.052=23.40
take the sum of dollar amount and interest decimal and multiply by # of years of interest ex:3 years *23.40 =70.20 interest and that is how you do it
Nishi will have amounts as $3300, $3750, $4050, and $4500 after 2, 5, 7, and 10 years respectively.
What is simple interest?The formula for simple interest is:
I = Prt
Where:
I = Interest earned
P = Principal (amount invested)
r = Interest rate (as a decimal)
t = Time (in years)
Using the simple interest formula to calculate how much Nishi will have after a certain number of years.
2 years:
I = Prt = 3000 x 0.05 x 2 = $300
Total amount after 2 years = P + I = $3300
5 years:
I = Prt = 3000 x 0.05 x 5 = $750
Total amount after 5 years = P + I = $3750
7 years:
I = Prt = 3000 x 0.05 x 7 = $1050
Total amount after 7 years = P + I = $4050
10 years:
I = Prt = 3000 x 0.05 x 10 = $1500
Total amount after 10 years = P + I = $4500
