1 answer:

6 0

Hey there!

Simplify 1/2

2/5+1/2.

Then, simplify 2/5

$\left[\begin{array}{ccc}\boxed{ \frac{L. \ Multi. \ * L. \ Num}{L.C.M}}= \frac{2*2}{10} \end{array}\right]$

$\boxed{\boxed{ \frac{2*2+5}{10} = \frac{9}{10}}} \\ \\ 9/10 \ would \ be \ your \ answer!$

I Hope this helps you!

How do I figure out how to find the solutions to the system of equations

OlgaM077 [116]

Answer:

This system of equations has no solution.

Step-by-step explanation:

Solving a system of equations can be done using a few different methods. Since your second equation is already solved for 'y', you can substitute this expression (- $\frac{1}{2}$ x + 3) for the value of 'y' in the first equation:

2x + 4(- $\frac{1}{2}$ x + 3) = 10

Distribute: 2x - 2x + 12 = 10

Combine like terms: 0 + 12 = 10 or 12 ≠ 10

Since the variables cancel out and 12 ≠ 10, there are no solutions to this system.

A parallelogram has an area of 300 square kilometers and a height of 20 kilometers. What is the length of the base?

Neko [114]

Answer: the length of the base is 15 kilometers.

Step-by-step explanation:

formula : Area of parrallelogram = Length of base x height

Given: Area of parallelogram = 300 square kilometers

height = 20 kilometers

Substituting values in the formula , we get

300 = Length of base x 20

Length of base = $\frac{300}{20}$

= 15 kilometers

Hence, the length of the base is 15 kilometers.

Pleaseeeeeeee help .......ASAP

Answer:

Option A

Step-by-step explanation:

Given:

Center of circle = (h,k)= (3,8)

Radius = r = 5

The standard form of equation of circle with center and radius is:

$(x-h)^2+(y-k)^2=r^2\\Putting\ the\ values\\(x-3)^2+(y-8)^2=(5)^2\\Simplifying\\x^2+9-6x+y^2+64-16y=25\\x^2+y^2-6x-16y+9+64=25\\x^2+y^2-6x-16y+73=25\\x^2+y^2-6x-16y+73-25=0\\x^2+y^2-6x-16y+48=0$

Therefore, the general form of the equation of circle given is:

$x^2+y^2-6x-16y+48=0$

Hence, option A is correct ..

Using the graph below which of the following is a gas

dimulka [17.4K]

Using the graph of solubility, D. Ce₂(SO₄)₃ is a gas

A gas is a state of matter with no fixed shape or volume.

<h3>What is solubility?</h3>

Solubility of a substance is the amount of solute that can dissolve in unit volume of solvent at a given temperature.

<h3>Which of the following compounds is a gas?</h3>

Note that the solubility of a substance depends on the temperature

For gases, the solubility decreses with incresing temperature
For liquids, temperature has no effect on solubility and
For solids, the solubility increases with temperature if the reaction is endothermixc and dedreases with temperature if the reaction is exothermic.

From the graph above, we see that the compound with the least solubility is Ce₂(SO₄)₃. Since the solubility of gases derease with increasing temperature, thus Ce₂(SO₄)₃ is a gas

So, using the graph of solubility, D. Ce₂(SO₄)₃ is a gas
