how do you balance ___NaBr + ___Ca--> CaBr2 + Na​

Answer:

Given a figure that is broken into a rectangle and triangle.

The dimensions of the rectangle are:

Base : 5 ft

Height : 1/3 ft

The dimensions of the triangle are :

Base : 3 upon 2/3 ft

Height : 2 ft

The area of the figure calculated below :-

Area of rectangle + Area of triangle

Area of rectangle + Area of triangleLB + 1/2BH

(5×1/3) + (1/3+3upon2/3×2)

The result is simplified below :-

5/3+11/3

5+11/3

16/3 ft

51/3 ft square.

The area of the figure is 5 and one third square feet.

Answer:

5 1/3

Answer:

[tex]\frac{4}{3} \text \ yards\ of\ wire[/tex]

Step-by-step explanation:

She uses 4/5 yards of wire to make 3 necklaces

Then

In Oder to make 1 necklace she use :

[tex]\frac{\left( \frac{4}{5} \right) }{3} =\frac{\frac{4}{5} }{\frac{3}{1} } =\frac{4}{5} \times \frac{1}{3} = \frac{4}{15}\ \ \small\text yards\ of \ wire[/tex]

Now to make to make 5 of the same necklaces she needs :

[tex]\frac{4}{15} \times 5=\frac{4}{15} \times \frac{5}{1} =\frac{20}{15}= \frac{4}{3} \ \ \ \text \ yards\ of\ wire[/tex]

In order to make a the subject of this equation , we need to get a by itself .

The current equation is :

v = u + at

Subtract u on both sides :

v-u=at

Now, divide by t on both sides :

v-u/t=a

[tex]\boxed{\\\begin{minipage}{3cm}Equation \\ a=$\displaystyle\frac{v-u}{t} $ \\ \end{minipage}}[/tex]

The inverse of the function is f ( x )⁻¹ = x + 4

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = x - 4   be equation (1)

On simplifying , we get

The inverse of the function is given by replacing x with y

So , the value of the function is

y = x - 4

x = y + 4

On interchanging , we get

f ( x )⁻¹ = x + 4

Hence , the inverse is f ( x )⁻¹ = x + 4

Answer:

The boat is 26 mi far from dock .

Step-by-step explanation:

By using PGT

P²+B² = H²

=> 10² + 24² = c²

=> 100 + 576 = c²

=> 676 = c²

=> √676 = c

=> 26 = c

Answer:

26 miles

Step-by-step explanation:

We can use Pythagorean's Theorem for right triangles which states that:

[tex]a^2+b^2=c^2[/tex]

The values 'a' and 'b' are the shorter sides of the triangle, while the value 'c' is the longest side of the triangle. We are given the two shorter sides 'a' and 'b', so let's now find 'c':

[tex](24mi)^2+(10mi)^2=c^2[/tex]

[tex]576mi^2+100mi^2=c^2[/tex]

[tex]c^2=676mi^2[/tex]

[tex]c=\sqrt{676mi^2}[/tex]

[tex]c=26mi[/tex]

Answer:

It's B, because thats where the two points cross

Step-by-step explanation:

Answer:

Find the rectangle's area on the left hand side, using the formula:

A = l x w

Where 'l' represents the length and 'w' stands for the width.

Plug in what you know:-

A = l x w

A = 15 x 5

A = 75 square units is the area of the left rectangle.

Now let's find the rectangle's area on the right hand side, using the formula:

A = l x w

Where 'l' represents the length and 'w' stands for the width.

A = l x w

A = 15 x 4

A = 60 square units is the area of the right rectangle.

Now find the middle small horizontal rectangle's area, using the formula:

A = l x w

Where 'l' represents the length and 'w' stands for the width.

But, let's figure out the length first.

We know that from the left rectangle, the two side lengths beside the unknown length of the middle rectangle area 5 and 7.

The unknown length plus those two lengths (5&7) will have to equal 15 since that is the total length, so;

15 - (5 + 7) = x

15 - 12 = x

3 = x, so the unknown length of the middle rectangle is 3.

Plug in what you know into the formula:

A = l x w

A = 3 x 7

A = 21 square units is the area of the middle rectangle.
Now add up all the areas together:

75 + 60 + 21

= 156 square units is the area of the shape.

Answer:

y=40/183x

Answer: $126

Step-by-step explanation: 30/100 × 420/1

Answer:

the numbers are -5 and 3

Step-by-step explanation:

First of all, the question is asking you to find the values of x from the given inequalities.

-8x -19<21 and 3x - 4 < 5

group all liked terms, in other words, make x and its coefficient stand alone.

-8x < 21 + 19 and 3x < 5 + 4

-19 became +19 because it crossed the sign <, also -4 became +4 because it crossed the sign <.

so we get

-8x < 40 and 3x < 9

we divide each "x" by its coefficient

[tex] \frac{ - 8x}{ - 8} < \frac{40}{ - 8} \: and \: \frac{3x}{3} < \frac{9}{3} [/tex]

then we get

x < -5 and x < 3

but x is positive so it's greater than -5 so we get

x > -5 and x < 3
