Answer:
B. 325
Step-by-step explanation:
y = the total value of the amount of papers he has to deliver each week
44x + 61 = y
(7 days in a week - sunday = 6 days)
44(6) + 61 = y
264 + 61 = y

Answer:
see attached for a graph-1, -2.6, -497Step-by-step explanation:
The solution to a one-variable inequality can be graphed on a number line. The number line is shaded where the values satisfy the inequality. Boundaries of shaded regions are marked by points that are either a solid dot, or an open circle, depending on whether the point is included in the solution or not.
__
Here, the inequality tells us any value of x that is less than or equal to -1 will satisfy the inequality. Since -1 is part of the solution set, that boundary point will be marked with a solid dot. Values less than -1 are shown on a number line to the left of the point marked -1.
The graph will be a solid dot at x=-1, and shading to its left.
__
Possible solutions are any values less than or equal to -1. Some are ...
-1

Can someone explain how to do this plez I NEED HELP
Answer:
42
Step-by-step explanation:
well , here we can find the unknown variable which is X
127 = 3X+2 ( vertically opposite angles are equal)
127 = 3X+2
3x+2= 127
collecting like terms
3x = 127-2
3x = 125
dividing bothsides by 3
3x/3 = 125/3
x = 41.66
x = 42 (approximately)

What can you say about the mean rainfall when comparing the two time periods?
The mean in period 2 is higher than the mean in period 1.
The mean in period 1 is higher than the mean in period 2.
The mean in period 1 is the same as the mean in period 2.
Answer:
[tex]\bullet \ \large\text{The mean in period 2 is higher than the mean in period 1.}[/tex]
Step-by-step explanation:
the mean in period 1 :
(2.3+2.1+2.2+2.2+2.2+2.1+2.4+2.5+2.2+2.0+1.9+1.9+2.1+2.2+2.3)÷15=21.733...
the mean in period 2 :
(2.3+2.1+3.3+1.5+3.6+1.6+3.0+1.1+4.7+2.1+2.4+1.9+2.8+0.5+2.3)÷15=23.466...
Since 23.466 > 21.733 then “The mean in period 2 is higher than the mean in period 1”.
Given that A = {1, 2, 3, 4, 5, 6] maps respectively to B = {3, 4, 5, 6, 7, 8). Find an injective function f(x) such that f: A → B. Hint: Can you depict any relationship between sets A and B?
Answer: f(x) = x + 2
Step-by-step explanation:
A = {1, 2, 3, 4, 5, 6]
B = {3, 4, 5, 6, 7, 8)
for each A, B is 2 more
f(1) = 1 + 2 = 3
f(2) = 2 + 2 = 4
f(3) = 3 + 2 = 5
and so on...
⇒ f(x) = x + 2

Find the area of the window
Answer:
Area = 1250cm²
Step-by-step explanation:
Area of a kite = pq/2
where p and q are diagonals
p = 25+25 = 50
q = 30+ 20 = 50
Area of a kite = pq/2
Area = (50*50 ) / 2
Area = 1250cm²
Find the area of the shapes below. Make sure to label your answers with units.
Figure a: The area of the triangle is 13.3 sq. km.
Figure b: The area of the rectangle is 57.4 sq. cm.
Figure c: The area of the parallelogram is 45.5 sq. km.
Figure d: The area of the trapezoid is 24.36 sq. m.
What is the area of a two-dimensional figure?The area of a two-dimensional closed figure is the total space within its boundary.
How to solve the question?In the question, we are asked to find the area of the given shapes.
Figure a:-
It is showing a triangle.
The area of a triangle is calculated using the formula:
Area = (1/2)*Base*Height.
Thus, the area of the triangle
= (1/2)*7*3.8 sq. km
= 13.3 sq. km.
Figure b:-
It is showing a rectangle.
The area of a rectangle is calculated using the formula:
Area = Length*Width.
Thus, the area of the rectangle
= 8.2*7 sq. cm
= 57.4 sq. cm.
Figure c:-
It is showing a parallelogram.
The area of a parallelogram is calculated using the formula:
Area = Base*Height.
Thus, the area of the parallelogram
= 9.1 * 5 sq. km
= 45.5 sq. km.
Figure d:-
It is showing a trapezoid.
The area of a trapezoid is calculated using the formula:
Area = (1/2)*(Sum of parallel sides)*(height).
Thus, the area of the trapezoid
= (1/2)*(2.7 + 8.9)*4.2 sq. m.
= 11.6 * 2.1 sq. m.
= 24.36 sq. m.

A car originally priced at $8,900 is on sale at 15% off. If the sales tax rate is 8.25%, how many dollars is the sale price of the car
If there is 15% off and the sales tax rate is 8.25%. Then the price of the car will be $ 8,189.11.
What is the percentage?The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.
A car originally priced at $8,900 is on sale at 15% off. If the sales tax rate is 8.25%.
The cost after 15% off will be
→ 0.85 × $8,900
→ $ 7,565
Then the final cost after the sale tax of 8.25% will be
Cost = $ 7,565 × 1.0825
Cost = $ 8,189.11

If applicable, round your answer to the nearest whole number.
The lengths on the figure are not drawn accurately.
28
53
117
Answer:
FH = 108
Step-by-step explanation:
The given figure requires we use the Pythagorean theorem to write two relations involving right triangle side lengths. The Pythagorean theorem tells us the square of the hypotenuse is the sum of the squares of the other two sides.
__
Triangle EGH:EG² = GH² +HE²
GH² = EG² -HE² = 53² -28² = 2025 . . . . . solve for GH², use given values
Triangle FGH:FG² = GH² +FH²
FH² = FG² -GH² = 117² -2025 = 11664 . . . . solve for FH², use known values
FH = √11664 = 108 . . . . . take the square root
The length FH is 108.
Solve the system by substitution.
y= -6x-7
y= -7x
Answer:
x = 7
y = -49
Step-by-step explanation:
Solving system of equation by substitution method.y = -6x - 7 ---------------(I)
y = -7x -------------------(II)
Substitute y = -7x in equation (I)
-7x = -6x - 7
-7x + 6x = -7
-x = -7
Multiply both sides by (-1)
[tex]\sf \boxed{\bf x = 7}[/tex]
Substitute x =7 in equation (II)
y = -7*7
[tex]\sf \boxed{\bf y = -49}[/tex]
Answer:
X = 7 Y = -49
Step-by-step explanation:
Y= -6 X -7---------(1)
Y= -7 X ------------(2)
using substitution method, substitute equation two into equation one-7 X = -6X -7
-7 X+6X = -7
- X = -7
cancelling the - sign on bothsides
X = 7
put X = 7 into equation (2)
Y = -7(7)
Y = -49
therefore, X = 7 Y= -49

Find the average rate of change of the function, f (x) = log₂ (4x) on the interval of x = 2 to x = 8.
Answer:
1/3
Step-by-step explanation:
The average rate of change of a function f(x) on an interval [a, b] is given by the formula ...
rate of change = (f(b) -f(a))/(b -a)
__
For the given function and interval, this is ...
(log₂(4·8) -log₂(4·2))/(8 -2) = (5 -3)/(6) = 1/3
The average rate of change is 1/3.

(5-3i)(x-yi) = 3(x+2yi)+1-2i
Answer:
(x, y) = (17/31, 1/31)
Step-by-step explanation:
Simplify the given equation, then equate real parts and equate imaginary parts. This will give you two equations in the two unknowns.
__
simplify(5 -3i)(x -yi) = 3(x +2yi) +1 -2i
5x -5yi -3xi +3yi² = 3x +6yi +1 -2i
(5x -3y) +i(-5y -3x) = (3x +1) +i(6y -2)
equate real, imaginary partsThis resolves to the two equations ...
5x -3y = 3x +1-5y -3x = 6y -2solve the systemPutting these equations into general form gives ...
