The retail inventory value of an item is the item's retail price times the quantity in stock. If a pack of cookies' retail price is $2.98 and there are 9 items in inventory, what is the total retail value?

Answer:

2 quarts of 100% antifreeze.

Step-by-step explanation:

5 quarts/ .40 * x/ 1

.40x= 5

x=2

2 quarts of pure antifreeze must be added to 5 quarts of a 40​% antifreeze solution to obtain a 50​% antifreeze​ solution.

Looking at the concentrations.

100% of x quarts is x quarts of antifreeze.

30% of 5 quarts is .3(5) quarts antifreeze.

Adding that we have 5+x quarts and we want

50% of that to be antifreeze so the total is

.5(x + 5)

x + .3(5) = .5(5+x)

x + 1.5 = 2.5 + .5x

x - .5x = 2.5 - 1.5

.5x = 1

x = 1/.5 = 2 quarts pure antifreeze.

Answer:S = 70,000 + 5000n

The equation that can be used to represent Josephs salary after working n years for the company is S = 70,000 + 5000n

The equation:

S = 70,000 + 5000(n)

S = 70,000 + 5000n

If n = 2

S = 70,000 + 5000n

= 70,000 + 5000(2)

= 70,000 + 10,000

= $80,000

Answer: (-2,-7)

Step-by-step explanation:

The coordinates of  B is  (-2, -7).

Coordinate geometry is defined as the study of geometry using the coordinate points. Coordinate geometry is required to provide a link between algebra and geometry through the use of line and curve graphs.]

Given:

Let the coordinates of  B be (x, y).

We have to find the coordinates of  B.

According to given question we have,

Then, (x + 2) / 2 = x-coordinate of M = 0.

So, x = -2.

(y + 1) / 2 = y-coordinate of M = -3.  

So, y = -7.

Therefore,  the coordinates of  B is  (-2, -7).

Hey there!!!

Here,

Triangle BCM and triangle ABC are 2 isosceles triangle.

Solving in triangle BCM.

Angle CBM = 31° { it is the base angle.}

Angle CBM + 31° + angle BCM = 180° { sum of interior angle of a triangle is 180°}.

31°+31°+ angle BCM = 180°

Angle BCM = 180° - 62°

Therefore the measure of angle BCM = 118°.

Again,

Solving in triangle ABC.

Angle BCM + angle ACB = 180° { being linear pair}.

118°+ angle ACB = 180°

Angle ACB = 180°-118°

Therefore the measure of angle ACB is 62°.

Angle ACB = angle BAC (Base of an isosceles triangle).

Therefore the measure of angle BAC = 62°.

Now, To find x,

Angle BAC + angle ACB + angle x = 180° (sun of interior angle of a triangle is 180°).

62°+62°+angle x = 180°

Therefore the measure of angle x is 56°.

Answer:

y=12

Step-by-step explanation:

First we should rewrite the left side to look like

4y/3=16

Then multiply 3 to both sides

4y=48

Now divide by 4

y=12

The equivalent value of the expression is y = 12

Given data ,

Let the equation be represented as A

Now , the value of A is

( 4/3 )y = 16

On simplifying the equation , we get

( 4/3 )y = 16

So , the left hand side of the equation is equated to the right hand side by the value of ( 16 )

Divide by 4 on both sides , we get

( 1/3 )y = 16/4

( 1/3 )y = 4

Multiply by 3 on both sides , we get

y = 4 x 3

On simplifying , we get

y = 12

Therefore , the value of y = 12

Hence , the expression is y = 12

Answer:

a can be anything. There are infinite solutions.

Step-by-step explanation:

[tex]4(a+2)=8+4a[/tex]

Expand:

[tex]4a+4\times\:2=8+4a[/tex]

[tex]4a+8=8+4a[/tex]

Subtract 8 from both sides:

[tex]4a+8-8=8+4a-8[/tex]

[tex]4a=4a[/tex]

Subtract 4a from both sides:

[tex]4a-4a=4a-4a[/tex]

[tex]0=0[/tex]

Since both sides are equal, a has infinite solutions as no matter what value it is, it will not affect the end result of [tex]0=0[/tex] which is true.
