Step-by-step explanation:
The question is incomplete. However, I will solve using the following assumptions.
Job A:
[tex]y = 2x + 5[/tex]
Job B
[tex]\begin{array}{cccccc}x & {1} & {2} & {3} & {4} & {5} \ \\ y & {6} & {10} & {14} & {18} & {22} \ \end{array}[/tex]
The first step is to calculate the rate of Job B using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where:
[tex](x_1,y_1) = (1,6)[/tex]
[tex](x_2,y_2) = (2,10)[/tex]
So, we have:
[tex]m = \frac{10 - 6}{2 - 1}[/tex]
[tex]m = \frac{4}{1}[/tex]
[tex]m = 4[/tex]
So, the hourly rate of job B is $4/hr
For Job A:
[tex]y = 2x + 5[/tex]
A linear equation has the form:
[tex]y = mx + b[/tex]
Where m is the rate
By comparison:
[tex]m = 2[/tex]
So, the hourly rate of Job A is $2/hr
Comparing both rates, we can draw the following conclusions;
The hourly rate of Job A is greater than the hourly rate of Job BThe hourly rate of Job A is twice the hourly rate of Job B.identifica los factores en los siguientes productos de polinomios.

The number of bacteria in a petri dish is 50,000 (on day 0) if the amount is doubling each day by when will the number of bacteria be 400,000. Let x represent the number of days and f(x) represent the amount of bacteria. Write an equation.
Answer:
f(x) = 50000*2^x3 daysStep-by-step explanation:
Given:
Initial amount of bacteria = 50000Growth rate = 2 times a dayRequired equation:
f(x) = 50000*2^xSolve for x:
400000 = 50000*2^x2^x = 400000/500002^x = 82^x = 2^3x = 3After 3 days bacteria numbers will reach 400000

Find the approximate area of the triangle y x> O 30 square units O 15 square units 21 square units 45 square units
Answer:
Step-by-step explanation:
a right triangle is half of a rectangle and the area of a rectangle is
area of rectangle = length × width
Area of a triangle is one half times the length times the width
area of triangle = 1/2 × length × width
in this case
length is the number of the y units
width is the number of x axis unit
area of triangle = 1/2 × length × width
area of triangle = 1/2 × (y units) × (x units) you need to count and insert
the number of units into the
equation
area of triangle = 1/2 × (??? y units ) × (??? x units ) do the math yourself

What is the measure of ZXZY?
Answer:
measure of angle XZY = 52 degrees
Step-by-step explanation:
The sum of measure of angles of a circle is 360 degrees.
therefore, m(arc XY) = 360 - (110 + 146)
m(arc XY) = 360 - 256
= 104 degrees
angle XZY is an inscribed angle.
By the inscribed angle theorem, the measure of an inscribed angle is half the measure of the intercepted arc.
So, m( angle XZY) = 1/2 * 104
= 52 degrees.

B) chaim only established some of the necessary conditions for a congruence criterion.
C) chaim established all necessary conditions, but then used an inappropriate congruence criterion.
D) chaim used a criterion that does not guarantee congruence.
Plz help
The error Chaim made in his proof is: D. Chaim used a criterion (SSA) that does not guarantee congruence.
What is the Side-side-side Congruence Theorem (SSA)?The SSA congruence theorem only exist and holds true, only if the congruence non-included angles in both triangles are either obtuse or right angles and have two pairs of congruent sides.
Thus:
The two triangles given have a pair of non-included congruent angles that are less than 90 degrees.
Therefore, the error Chaim made in his proof is: D. Chaim used a criterion (SSA) that does not guarantee congruence.

The only given angle is 126°.
The angle to look for is marked by “))”
Answer:
117°Step-by-step explanation:
The central angle is twice the inscribed angle (same arc).
The inscribed angle forms a supplementary angle with the missing one (opposite angles of the cyclic quadrilateral).
The missing angle is:

The surface area of the prism is 456cm² and the volume is 408cm³
What is a prism?A prism is a solid shape that is bound on all its sides by plane faces. There are two types of faces in a prism. The top and bottom faces are identical and are called bases. A prism is named after the shape of these bases. For example, if a prism has a triangular base it is called a triangular prism.
here, we have,
The formula for the surface area of a prism is SA=2B+ph, where B, again, stands for the area of the base, p represents the perimeter of the base, and h stands for the height of the prism.
Base area = 1/2× 8× 6
= 4×6 = 24 cm²
perimeter of the base = 6+8+10 = 24cm²
therefore SA = 2(24)+24×17
= 48+408
= 456cm²
Volume of the prism = base area × height
= 24 × 17
= 408cm³

Answer:
34
Step-by-step explanation:
17.25/2 = 8.62500
8.62500/0.25 = 34 quarter coins,
