Answer: $860 this week.
Step-by-step explanation:
Paul worked 40 hours this week, and makes 21.50 dollars an hour. Gross pay means the amount of money paid before taxes.
So we don't need to calculate any taxes, which means all we need to do is multiply 21.50 by 40 hours, since he makes 21.50 an hour, and he worked 40 hours.
What is the equation of the line that passes through the point (-1, 5) and
has a slope of -3?
Answer:
Equation of line is given as y = mx + c, where m is the slope and c is the y-intercept.
Since slope is -3, equation is y = -3x + c.
Substitute point (-1,5) into equation to find c.
5 = -3(-1) + c
c = 2
Hence, equation of line is y = -3x + 2

Gigi makes a scale drawing of a patio the drawing below shows the two scales she used to plan two patios of different sizes
Gigi makes a scale drawing of a patio the drawing, The two scales are
Scale 1 is defined as 35ft by 25ft Scale 2 is defined as 56 ft by 40 ftThis is further explained below.
What are dimensions?Generally, In mathematics, a dimension is a measurement that may be taken in one direction to determine the size or distance of an item, area, or space.
To put it another way, it is the process of determining the dimensions of anything by calculating its length, breadth, and height.
Actual ratio measurements with a scale of 1
For the Lenght
Length=7 cm
Length =7*5
Lenght=35 ft
Width=5 cm
Width=5*5
Width=25 ft
Therefore
The dimensions are 35 ft by 25 ft
Find the actual dimensions of a ratio with the scale 2
A scale of 2 is equal to
1 cm/8 ft
For Length=7 cm
L=7*8
L=56 ft
For Width=5 cm
W=5*8
W=40 ft

The proportional linear equation relationship has a unit rate of 1.6
How to plot the graph the line of the relationship?From the question, we have the statement to be:
The relationship between d and t is a proportional relationship An increase of 5 units in t causes an increase of 8 units in d.The above means that
5 * t = 8* d
Evaluate the products
So, we have the following equation
5t = 8d
Divide both sides of the equation by 5
So, we have the following equation
t = 1.6d
Next, we plot the graph of the equation
See attachment for the graph of the equation t = 1.6d
Also, we have
t = 1.6d
The above equation is a proportional linear equation
A proportional linear equation is represented as
t = md
Where m represents the unit rate
So, we have
m =1.6
Hence, the unit rate of the relationship is 1.6

The shaded angles in the given diagram can be named as:
1. ∠ABC; ∠1; and ∠B.
2. ∠JKM; ∠2; ∠K.
3. ∠CBJ ≅ ∠DHG
4. ∠FJH ≅ ∠AJB
5. m∠JAB = 75°.
6. m∠JBC = 130°.
How to Name an Angle?We can name a given angle by:
Using the three letters that form the angle, i.e. ∠ABC.Naming the angle using numbers, i.e. ∠1By using the letter of the vertex of the angle only, i.e. ∠B.1. The three angles can be named as:
Angle ABC or ∠ABC
Angle 1 or ∠1
Angle ∠B or ∠B.
2. The shaded angle can be named as:
Angle JKM or ∠JKM
Angle 2 or ∠2
Angle ∠K or ∠K.
Two angles with the same marks on a diagram are congruent to each other. Therefore:
3. ∠CBJ ≅ ∠DHG
4. ∠FJH ≅ ∠AJB
Angles that are congruent to each other have the equal angle measure, therefore:
5. ∠EFD ≅ ∠JAB
Therefore, If m∠EFD = 75°, then m∠JAB = 75°.
6. ∠GHF ≅ ∠JBC
Therefore, If m∠GHF = 130°, then m∠JBC = 130°.

Which statement is true about the graph of the line whose equation is y = 8?
Answer:
A. the line is parallel to the x axis
Step-by-step explanation:
B is incorrect because it will be intersecting the y axis therefore not being parallel
C is incorrect because It doesn't pass through the origin (origin is (0, 0) btw) it actually passes thru the point (0, 8) so this choice is wrong
D is incorrect because It doesn't give us enough info that the slope is 8 so we can't tell. Also if y = 8 it will just be a straight line so the slope will actually be 0 im pretty sure
A is correct because it is parallel if y = 8 and x axis kept going in a straight line they will never touch so that means it it parallel

Julia had pizza delivered. Julia tips $5 for deliveries or 10% of the purchase, whichever is higher. The pizza delivered cost $35.50.
How much will Julia tip?
10% of $35.50 = 0.10*35.50 = 3.55
If Julia goes with the 10% option, then she will tip $3.55
But she instead goes with the $5 tip because it's the larger of the two options. If the result of 10% of $35.50 was larger than 5, then she'd go with the 10% option instead.

How to find the time it will take the plane to cover a distance?The plane flew at a constant speed between Boston and Philadelphia.
An equation relating the distance travelled in miles, d, to the number of hours flying, t, is d = 350t.

where
t = time travelledd = distanceTherefore, let's find the time it will take to travel for 280 miles
d = 350t
d = 350 × t
280 = 350t

if f(x)=x^2, what is g(x)? the graph shows the points: (1, -1), (-1,3), (-3,-1)?
IMAGE OF QUESTION
ANSWER
[tex]g(x)=-(x+1)^2+3[/tex]EXPLANATION
We have that the function graphed g(x) is a transformation of:
[tex]f(x)=x^2[/tex]When the parent quadratic function f(x) is transformed, it takes the following form:
[tex]g(x)=a(x-h)^2+k[/tex]This form also represents the vertex form of a quadratic equation, where (h, k) is the vertex of the function.
This means that we can find the function by using the vertex of the function.
The vertex of a function is the maximum or minimum value of the function; from the given graph, it is a maximum value and it is located at:
[tex](h,k)=(-1,3)[/tex]Therefore, we can input this into the vertex form of the function:
[tex]\begin{gathered} g(x)=a(x-(-1))^2+3 \\ g(x)=a(x+1)^2+3 \end{gathered}[/tex]Now, we have to find the value of a. To do this, pick any coordinate point from the graph and input it into the function above.
Let us pick:
[tex](0,2)[/tex]Therefore, we have:
[tex]\begin{gathered} 2=a(0+1)^2+3 \\ 2=a\cdot1+3 \\ 2=a+3 \\ \Rightarrow a=2-3 \\ a=-1 \end{gathered}[/tex]Therefore, the function graphed above is:

The value of the hypotheses of the right angled triangle is found as √130.
What is meant by the right angled triangle?A right triangle is one in which one of interior angles is 90°. The hypotenuse is the longest side of the right triangle and also the side opposite this same right angle, while the height and base are the two arms of the right angle.In a right triangle, the right angle always has the largest.The longest side is the hypotenuse, which is the side opposite this same right angle.For the given right angled triangle,
The two side legs are given as 7 and 9.
By the Pythagorean theorem;
H² = P² + B²
Put the values;
H² = 7² + 9²
Simplifying;
H² = 49 + 81
H² = 130
Taking square root both sides.
H = √130
Thus, the value of the hypotheses of the right angled triangle is found as √130.
