Answer:

138 g of chlorine is required to produce 214 g of sodium chloride if we have 76 g of sodium.

Step-by-step explanation:

We are given:

Grams of Sodium = 76 g

Grams of Sodium Chloride = 214 g

We need to find how many grams of chlorine required to produce 214 g of sodium chloride

The equation will be:

[tex]Na \ + \ Cl \ -> NaCl\\76\ g \ \ \ x \ g \ \ \ \ \ \ \ \ 214 g[/tex]

We can write: 76 (g) + x (g)=214 (g)

Solving and finding value of x

x =214-76

x=138 g

So, 138 g of chlorine is required to produce 214 g of sodium chloride if we have 76 g of sodium.

Hey there!

Given;

Radius of a circle (r) = 7cm

Now;

We know that;

Area of circle (a) = π*(r^2)

= 3.14*(7^2)

= 3.14*49

= 153.86 cm^2

Therefore, the area of a circle is 153.86 cm^2.

Hope it helps...

Answer:

The bus driver drives 30 miles in 5 days.

Step-by-step explanation:

Hi,  

You can use the rule of three to solve this problem.

For the first step, we need to analyze the information given:

[tex]6 (miles) = 1 (day)[/tex]  

and we want to know how much miles the bus driver drives in 5 days:

[tex]x (miles) = 5 (day)[/tex]

Thus,

[tex]6 (miles) = 1 (day)[/tex]   ... (1)

[tex]x (miles) = 5 (day)[/tex]   ... (2)

Now, multiplying in a cross and  we have:

[tex]x *1 = 5*6 \\ x = 30[/tex]

Lastly, replacing the value of x in (2):

[tex]30 (miles) = 5 (day)[/tex]

and this is the answer

Answer:(1,-1)

Step-by-step explanation:

Y= -2x+1

3x -2(-2x*1)=5

3x+(4x-2)=5

7x-2 =5

+2 = +2

7x=7

x= 1

Solution : (1,-1)

Answer:

j=45 k=83 L=52

Step-by-step explanation:

j=x-7

k=2x-21

L=x

x-7+2x-21+x=180

4x-28=180

4x=208

x=52

The measure of the angles are; J = 48, K = 57 and L = 75

Linear pair of angles are produced when two lines intersect each other at a point. The sum of angles of the linear pair is always 180 degrees.

In order to determine the measure of these angles, we have to set J as x. then find the measure of all of these angles.

J = x

K = x + 9

L = 2x - 21

Now, we can add them all together and set equal to 180;

x + x + 9 + 2x - 21 = 180

4x - 12 = 180

4x = 192

x = 48

Now that we have;

J = x = 48

K = x + 9 = 48 + 9 = 57

L = 2x - 21 = 2(48) - 21 = 96 - 21

L = 75

Hence, The measure of the angles are; J = 48, K = 57 and L = 75

Answer:

The area would decrease

Step-by-step explanation:

So if the base was 4ft and the height was 2ft then the area would be 8ft^2. because area is base times height. so if 4 times 1/2 is 2 and 2 time 1/2 is 1 so the area would be 2ft^2

Answer:

Step-by-step explanation:

We know that Krutika’s share is three times Natasha’s because they are split in a 3:1 ratio. So we can say:

K=3N

We also know that Krutika’s share is £52 more than Natasha’s:

K= (N+£52)

Substituting what we know about K allows us to reduce the equation to one variable:

3N=N+£52

Clean that up by subtracting N from both sides, leaving us with variables only on one side of the equation.

2N=£52

Which means that we can divide both sides by two to get our answer.

N=£26.

So, of the original £104, Krutika got £78 and Natasha got £26.

Step-by-step explanation:

Answer/Step-by-step explanation:

This is a proportional relationship between amount of strawberries and the amount of bananas needed in making smoothie.

Thus, a constant of proportionality, k, is a ratio that exist between both quantities.

k = y/x = amount of strawberry/amount of bananas.

Since we are given that a recipe of smoothie contains 5 cups of strawberries for every 2 cups of bananas, therefore,

k = ⁵/2 = 2.5.

Any point that will be on the line shown must have the same value of k (y/x).

Thus, given the point (1, 2.5). The ratio between y and x is:

k = 2.5/1 = 2.5.

Since this also shows the same constant of proportionality as 2.5, therefore, the point is also on the line.

Answer:

(-4, -1), (0, 2), (4, 5)

Step-by-step explanation:

(-4, -1): If you see the x-axis and trace -4 and -1 from the y-axis, they both lead to a point that is on the graph.

(-2, 1): The graph, at -2 on the x-axis, lies at height 0.5, so 1 is wrong.

(0, 2): At 0, the graph lies on 2.

(4, 5): At 4 on the x-axis, the graph lies at height 5.

(2, 0): The graph is already at height 3.5 when at length 2.
