Metal A has a density of 2.4g/cm3 and metal B has a density of 1.8 g/cm3.Their masses are combined in the ratio 2 : 3 to make metal C which has a mass of 60 grams.Find the density of the metal C
Answer: 2 g/cm^3
Step-by-step explanation:
Remember the relation:
density = mass/volume.
Now, we know that:
Density of metal A = 2.4 g/cm^3
Density of metal B = 1.8 g/cm^3
We know that their masses are combined in the ratio 2:3
Then out of the total mass of metal C, 2 parts are from metal A and 3 parts are from metal B.
Mass of metal C = 60g
mass of metal A = (2/5)*60g =24g
mass of metal B = (3/5)*60g = 36g
Now that we know the mass of each metal, we can find their volumes by:
volume = mass/density
Volume of metal A = (24g)/(2.4g/cm^3) = 10cm^3
Volume of metal B = (36g)/(1.8g/cm^3) = 20cm^3
The total volume of metal C will be equal to the sum of the volumes of metal A and B, then:
Volume of metal C = 10cm^3 + 20cm^3 = 30cm^3
Then we know the volume and weight of metal C, then the density of metal C is:
Density of metal C = (60g)/(30cm^3)= 2 g/cm^3

DeShawn and Mike each improved their yards by planting rose bushes and geraniums. They
bought their supplies from the same store. DeShawn spent $13 on 1 rose bush and 4 geraniums.
Mike spent $56 on 10 rose bushes and 3 geraniums. Find the cost of one rose bush and the cost of one geranium.
Answer:
Cost of 1 rose bush = x = $5
Cost of 1 geraniums = y = $2
Step-by-step explanation:
DeShawn and Mike each improved their yards by planting rose bushes and geraniums. They bought their supplies from the same store.
Let us represent:
Cost of 1 rose bush = x
Cost of 1 geraniums = y
DeShawn spent $13 on 1 rose bush and 4 geraniums.
x + 4y = 13..... Equation 1
x = 13 - 4y
Mike spent $56 on 10 rose bushes and 3 geraniums.
10x + 3y = 56....... Equation 2
We substitute 13 - 4y for x in Equation 2
10(13 - 4y) + 3y = 56
130 - 40y + 3y = 56
Collect like terms
- 40y + 3y = 56 - 130
-37y = -74
y = -74/37
y = $2
Solving for x
x = 13 - 4y
x = _13 - 4 × $2
x = $13 - $8
x = $5
Therefore,
Cost of 1 rose bush = x = $5
Cost of 1 geraniums = y = $2

A pile of sand has a weight of 60 kg
The sand is put into a small bag, a medium bag and a large bag in the ratio 2:3:7
Work out the weight of the sand in each bag
Small bag = 2x
Medium bag = 3x
Large bag = 7x
2x + 3x + 7x = 60
12x = 60
x = 60/12
x = 5
Small bag = 2(5) = 10 kg
Medium bag = 3(5) = 15 kg
Large bag = 7(5) = 35 kg
Done.
2) Uma equação foi descrita da seguinte maneira:
(k² – 4) x³ + ( k – 2 )x² + 7x - 8 = 0
Analisando os coeficientes, o valor de k que faz com que essa equação seja uma equação do 2º grau é:
a) k = ± 2
b) k = + 2
c) k = - 2
d) k = 0
e) k = 4
Answer:
c) k = - 2
Step-by-step explanation:
Equação de Segundo Grau:
Uma equação de segundo grau tem o seguinte formato:
[tex]ax^2 + bx + c = 0[/tex]
Em que [tex]a \neq 0[/tex]
Caso tenham potências de x maiores que dois, o termo que multiplica essas potências deve ser 0.
Neste exercício:
Tem-se a seguinte equação:
[tex](k^2 - 4)x^3 + (k-2)x^2 + 7x - 8 = 0[/tex]
Para ser do segundo grau, necessita-se que:
[tex]k^2 - 4 = 0[/tex]
[tex]k^2 = 4[/tex]
[tex]k = \pm \sqrt{4}[/tex]
[tex]k = \pm 2[/tex]
E também
[tex]k - 2 \neq 0[/tex]
[tex]k \neq 2[/tex]
A intersecção entre [tex]k = \pm 2[/tex] e [tex]k \neq 2[/tex] é [tex]k = -2[/tex], e portanto a resposta é dada pela alternativa c.
O valor de k que torna a equação uma equação de segundo grau para a equação considerada é dado por: Opção C: k = -2
What is degree of an equation?For a single variable equation, degree of an equation is the highest power the variable possess, such that its coefficient is non-zero.
A second degree equation is that equation where the maximum power involved in that equation is 2 (such that its coefficient is non-zero).
For this case, the considered equation is:
(k² – 4) x³ + ( k – 2 )x² + 7x - 8 = 0
For making it second degree, we would have to vanish the coefficient of x³, and by vanish, we mean we would like to make it 0, but simultaneously, we'd have to take care that coefficient of x² doesn't become 0 as we need it to be non-zero.
So we get two mathematical statements:
Coefficient of x³ = 0Coefficient of x² ≠ 0or
[tex](k^2 - 4) = 0\\k - 2 \neq 0[/tex]
Taking first equation, we get:
[tex]k^2 -4 = 0\\k^2 = 4\\k = \pm \sqrt{4} = \pm 2[/tex]
Thus, k = 2 or k = -2
From second statement, we get:
[tex]k -2 \neq 0\\\text{adding 2 on both the sides}\\k \neq 2[/tex]
Thus, from both the results, we conclude that k = -2 is correct choice.
Thus, the value of k that makes the equation a second degree equation for the considered equation is given by: Option C: k = -2

Renting jet skis from Jerry's water sports costs $20.00 per hour plus a one-time fee of $8.00. Renting jet skis from Splash of fun costs $25.00 per hour with no one-time fee. The cost to rent a jet ski depends on the total number of hours,h, rented. How many hours must you rent a jet ski for the cost to be the same at jerry's water sports and at splash of fun?
Answer:
The indifference point is 1.6 hours.
Step-by-step explanation:
Giving the following information:
Jerry's water sports:
Variable cost= $20.00 per hour
Fixed cost= $8
Splash of fun:
Variable cost= $25.00 per hour.
First, we need to establish the system of equations:
Jerry= 8 + 20x
Splash= 25x
x= number of hours
Now, we need to equal both formulas and isolate x:
20x + 8 = 25x
8=5x
1.6= x
The indifference point is 1.6 hours.
Prove:
erry= 8 + 20*1.6= $40
Splash= 25*1.6= $40

Write an equation in slope-intercept form of the line that passes through the points (-2, - 11) and (3,9).
The equation is y=
Answer:
y = 4x - 3
Step-by-step explanation:
(-2, -11) & (3, 9)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(9 - (-11)) / (3 - (-2))
Simplify the parentheses.
= (20) / (5)
Simplify the fraction.
20/5
= 4
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 4x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (3, 9). Plug in the x and y values into the x and y of the standard equation.
9 = 4(3) + b
To find b, multiply the slope and the input of x(3)
9 = 12 + b
Now, subtract 12 from both sides to isolate b.
-3 = b
Plug this into your standard equation.
y = 4x - 3
This is your equation.
Check this by plugging in the other point you have not checked yet (-2, -11).
y = 4x - 3
-11 = 4(-2) -3
-11 = -8 - 3
-11 = -11
Your equation is correct.
