Talia works 6 hours per day on fridays and saturdays each week. She earns $8. 20 per hour. What is her gross pay in a week?.

The amount of money that Alex will use to purchase the 5 x 7 print would be = $11.89.

An online printing service is the service that is rendered online that helps interested individuals to prepare their printed paper works.

The number of 4 x 6 prints(X) purchased by Alex = 29

The number of 5 x 7 prints (y) purchased by Alex = 16

The total amount he paid for the whole service = $22.89

The cost of 5 x 7 prints can be calculated using this expression;

22.89 - 0.84 = 22.05/2 = 11.025

Therefore the cost of 5×7 prints = 11.05+ 0.84 = $11.89.

Step-by-step explanation:

The flagpole, the shadow and the line connecting the tip of the shadow to the top of the flagpole construe a right-angle triangle with the flagpole and shadow being the legs of the triangle and the other the hypotenuse

Given flagpole height is 24 meters and shadow is 33 meters we can compute the third side using the Pythagorean Theorem for the hypotenuse:

[tex]c = \sqrt{a^{2} + b^{2}}[/tex]

Substituting known values we get
[tex]c = \sqrt{24^{2} + 33^{2}}\\\\c = \sqrt{576 + 1089}\\\\c = \sqrt{1665}\\\\c=40.804 \;meters[/tex]

The slope and y-intercept of the linear function y = -10x + 1 are -10 and (0,1) respectively.

The given linear function is y = -10x + 1.

The slope of a linear function is the coefficient of the x-term. In this case, the slope is -10.

The y-intercept of a linear function is the point at which the line crosses the y-axis. To find the y-intercept, we can substitute x = 0 into the equation and solve for y.

y = -10(0) + 1

y = 1

So, the y-intercept is (0,1).

Therefore, the slope and y-intercept of the linear function y = -10x + 1 are -10 and (0,1) respectively.

Circle M has a center (h+d, k+e) and the radius is rs. Therefore, option C is the correct answer.

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

Given that, circle B has a center (h, k) and a raius of r. Circle B is translated d units to the right and e units up. Then it is dilated about its new center by a scale factor s resulting in a new circle

Translation rules:

When the shape is moved towards the right by k units, then replace x with x + k.

When the shape is moved up by k units, then replace y with y + k.

Now, (h, k)→(h+d, k+e) and the radius is rs.

Julio needs to prove that two sides of the two triangles are congruent, in addition to the hypotenuse and one set of legs that are already congruent, to use the SAS Triangle Congruence Theorem.

Congruence, in mathematics, a term employed in several senses, each connoting harmonious relation, agreement, or correspondence .Two geometric figures are said to be congruent, or to be in the relation of congruence, if it is possible to superpose one of them on the other so that they coincide throughout. Thus two triangles are congruent if two sides and their included angle in the one are equal to two sides and their included angle in the other.

This idea of congruence seems to be founded on that of a "rigid body," which may be moved from place to place without change in the internal relations of its parts. The position of a straight line (of infinite extent) in space may be specified by assigning four suitably chosen coordinates. A congruence of lines in space is the set of lines obtained when the four coordinates of each line satisfy two given conditions. For example, all the lines cutting each of two given curves form a congruence.

The total salary of Saul is given by the equation A = $ 1,740

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total salary of Saul be represented as A

Now , the equation will be

The basic monthly salary of Saul = $ 1,500

The total commission percentage of Saul = 4 %

The minimum amount of items to sell = $ 20,000

The amount of items worth sold = $ 26,000

So , the extra amount of items sold by Saul = 26,000 - 20,000 = $ 6,000

Now ,

The total salary of Saul A = basic monthly salary of Saul + ( commission percentage x extra amount of items sold by Saul )

Substituting the values in the equation , we get

The total salary of Saul A = 1,500 + ( 4 % x 6,000 )

On simplifying the equation , we get

The total salary of Saul A = 1500 + ( 4/100 ) x 6,000

The total salary of Saul A = 1500 + 240

The total salary of Saul A = 1,740

Answer:

  (x, y) = (2, 4)

Step-by-step explanation:

You want to solve the system of equations ...

There are numerous ways to solve this system of equations. One of the simplest is to use a graphing calculator. (See the attachment)

  (x, y) = (2, 4)

The second equation gives an expression for x that can be substituted into the first equation:

  y = -2(y -2) +8

  3y = 12 . . . . . . . . add 2y and simplify

  y = 4

  4-2 = x = 2

The solution is (x, y) = (2, 4).

The y-variable has a coefficient of 1 on the left side of the equal sign, so we can eliminate the y-variable by subtracting the second equation from the first.

  (y) -(y -2) = (-2x+8) -(x)

  2 = -3x +8 . . . . . . . . . . . simplify

  3x = 6 . . . . . . . . . . add 3x-2

  x = 2 . . . . . . . . divide by 3

  y = -2(2) +8 = 4 . . . . . substitute for x in the first equation

The solution is (x, y) = (2, 4).

The length of TS  in ΔTRS using Similarity of triange is 12 cm .

If two items have the same shape or have the same shape as their mirror images, they are said to be Similar. One can be produced from the other more accurately by evenly scaling it, perhaps with the addition of further translation, rotation, and reflection.

If the sides are in the same ratio or proportion and the angles are equal (corresponding angles), two triangles will be comparable (corresponding sides). Similar triangles may have varying individual side lengths, but they must have equal angles and the same scale factor or matching ratio of the side lengths. If two triangles resemble one another, then

What is an equivalent expression?

An equivalent expression is a mathematical expression that has the same value as another expression, even though they may appear to be different. Equivalent expressions are obtained by using the same operations or by making substitutions that preserve the value of the expression.

The expressions -6z + (-5.5) and 3.5z - 5y - 2.5 are not equivalent. They have different coefficients for the variables z and y, and different constants. To determine if two expressions are equivalent, you need to check that they have the same value for all possible values of the variables.

(0.35x) + (0.60y) = 0.55(x+y) (because we're calculating the amount of salt in each solution and the combination contains 55% salt)

We may take the first equation and replace it in the second equation:

(0.35x) + (0.60y) = 0.55(50) (50)

0.35x + 0.60y = 27.5 when x is substituted.

A system of two equations with two variables is now available:

x + y = 50\s0.35x + 0.60y = 27.5

To determine one of the variables in terms of the other, we may utilize the first equation. Let's figure out y:

y = 50 - x

We now change y in the second equation to the following expression:

0.35x + 0.60(50-x) = 27.5

Finding the value of x:

0.35x + 30 - 0.6x = 27.5

0.25x= -2.5

x= -10

Since the number of ounces cannot be negative, the answer is illogical. As a result, you should double-check your calculations or determine if the issue statement contains a mistake.
