A mathematical statement known as an equation is made up of two expressions joined together by the equal sign.. A formula would be 3x - 5 = 16, for instance. After solving this equation, we learn that the value of the variable x is 7.

You need 50 cc of a 12% alcohol solution.

We need 50 cc of the 12% alcohol solution, which we have at 10% and 15%.

Two equations were constructed: x = 10% volume and y = 15% volume.

a) x + y = 50

b) 50 ml at 12%, or.12 * 50, is equal to.1x +.15y = 6.0.

dividing equation "a" by -.1 and adding it to equation "b"

a) -.1x -.1y = -5

b) .1x +.15y = 6.0

.05y = 1

X would equal 30 ml of 10% since y = 20 ml of 15%.

The measure of angle H is 44°. in the parallelogram.

What is parallelogram?

A unique variety of quadrilateral made up of parallel lines is known as a parallelogram. A parallelogram can have any angle between its adjacent sides as long as its opposite sides are parallel. If two opposite sides of a quadrilateral are parallel and congruent, it will be a parallelogram. Consequently, a quadrilateral in which both pairs of opposite sides are parallel and equal is known as a parallelogram.

We can solve this easily using alternative interior angles. A parallelogram's interior is always 360 degrees, right?

(4x + 16)° + (2x - 16)° = 180

6x = 180

x = 180/6 = 30

So the angle H = 2*30 - 16 = 44°

To visualize the parallelogram, drawing it out is always helpful. Greg S., a widely renowned mathematician who specializes in geometry, says the answer is 44 degrees.

Hence The measure of angle H is 44°.

The total commission of Mr. Corona will be equal to $417.62

What is commission?

A commission is a proportion of all sales.

total sales x rate of commission equals commission.

Multiply the commission rate by the total sales to get the commission on a sale. Recall to convert the commission rate from a percent to a decimal first, just as we did for computing the sales tax.

As given in the question,

Mr. Corona receives 21% of the first $1500,

which he exceeded, so he will receive 21% x $1500 = 0.21 x $1500 = $315

He will receive 14$ of the amount over $1500,

which is $2233 - $1500 = $733

Out of this amount, he will be paid $733 x 14% = $733 x 0.14 = $102.62

Therefore, The total commission will be $315 + 102.62 = $417.62

For the given set of marbles at random draw 3 marbles without replacement then the probability of withdrawing all marbles are red is equal to 0.0545 and none of the given marbles are red is equal to 0.2378.

As given in the question,

Total number of marbles in a bag = 9 red + 6 white + 7 blue

                                                     = 22 marbles

Number of marbles drawn from a bag without replacement = 3

Probability of all the three marbles are red without replacement :

First marble is red = 9 /22

Second marble is red = 8 /21

Third marble is red = 7/20

Required probability of all marbles are red

= (9/22) (8/21)(7/20)

= 504/ 9240

= 0.0545 (round off to 4 decimals)

Probability of all the three marbles are not red without replacement :

First marble is not red =(1- 9 /22)

                             = 13/22

Second marble is not red = 1- (8 /21)

                                        = 13/21

Third marble is not red = 1- (7/20)

                                    = 13/20

Required probability of all marbles are not red

= (13/22) (13/21)(13/20)

= 2197/ 9240

= 0.2378 (round off to 4 decimals)

Therefore, for the given set of marbles at random draw 3 marbles without replacement then the probability of withdrawing all marbles are red is equal to 0.0545 and none of the given marbles are red is equal to 0.2378.

The surface area of the unfolded prism is 77 square inches.

Herein we find a representation of an unfolded right prism with an isoceles triangle cross area, the surface area is the sum of the areas of all faces of the solid. There are a rectangle, two squares and two isosceles triangles as faces of the prisms. The area formulas for each expression are described below:

Rectangle

A = b · h

Where:

Isosceles triangle

A = (1 / 2) · b · h

Square

A = l²

Where l is the side length, in inches.

Now we proceed to determine the surface area of prism:

A = 2 · (5 in)² + (3 in) · (5 in) + 2 · (1 / 2) · (3 in) · (4 in)

hope it helps!

The image of  y = −2x^2 − 20x + 2 after a translation right 4 units and up 2 units is written in:

The graph will be a vertical parabola opening downwards

when the function y = −2x^2 − 20x + 2 translates right 4 units it gives  

y = -2(x - 4)^2 − 20(x - 4) + 2

going up two units

y = -2(x - 4)^2 − 20(x - 4) + 2 + 2

simplifying the equation further gives

y = -2(x - 4)(x - 4) − 20(x - 4) + 4

y = -2(x^2 - 8x + 16) - 20x - 80 + 4

y = -2x^2 + 16x - 20x - 32 - 80 + 4

y = -2x^2 - 4x - 108

completing the square

-2x^2 - 4x - 108 = 0

-2x^2 - 4x = 108

-2x^2 - 4x + (4/4)^2 = 108 -(4/4)^2

-2x^2 - 4x + (1)^2 = 108 - 1
