Solve for x. 9x - 18 = 7x + 30
Answer: x = 24
Step-by-step explanation:
9x - 18 = 7x + 30
9x - 7x = 30 + 18
2x = 48
x = 48/2 = 24
A new car is purchased for 15700 dollars. The value of the car depreciates at 7.5% per year. To the nearest year, how long will it be until the value of the car is 10100 dollars?
Answer:
10100=15700(1-0.075)^x
10100=15700(0.925)^x
divide both sides by 15700
0.925^x=101/157
convert decimal
(37/40)^x=101/157
take the log
x= log 37/40 (101/157)
x= 5.65824
It will take almost 6 years to depreciate the value of the car to 10100 dollars.

[tex](x^2+9x+10)(x-2)= \\\\x^3-2x^2+9x^2-18x+10x-20= \\\\x^3+7x^2-8x-20[/tex]
Jimmy is incorrect.
Using long division, you can find that the real answer.
First, subtract [tex]x^2(x-2)[/tex] from the original expression, leaving you with [tex]9x^2+2x-40[/tex].
Next, subtract [tex]9x(x-2)[/tex] from the expression, leaving you with [tex]20x-40[/tex]. Finally, subtract [tex]20(x-2)[/tex] from the expression, leaving you with a remainder of 0. This means that the real quotient is [tex]x^2+9x+20[/tex]. Hope this helps!
Point D is an interior of ABC. what is m DBC can u help me pls
Answer:
36.5 degrees
Step-by-step explanation:
angle abc is a straight angle ( which is 180 degrees )therefore:
angle ABD + angle DBC = angle ABC
substituting the given measurements gives us=
3x + 22 + x - 4 = 180
4x = 162
x = 40.5
the question asks us to find measure of angle DBC so we substitute x which =
measure DBC = x - 4
measure DBC = 40.5 - 4
measure DBC = 36.5 degrees
hope this helps!! :)

The object below is made of solid plastic. It is a cylinder with an indentation at the top
in the shape of a cone.
What is the volume to the nearest tenth of a cubic inch, of the plastic object?
Answer: 97.6 in3
Step-by-step explanation:
Hi, to answer this question we have to calculate the volume of the cylinder and subtract the volume of the cone:
Volume of a cylinder: π (diameter /2) ^2 (height)
Vcy = π (4 /2) ^2 (8) = π (2) ^2 (8) =100.5 in3
Volume of a cone = 1/3 π (diameter /2) ^2 (height)
V Co = 1/3 π (4/2) ^2 (0.7) = 1/3 π (2) ^2 (0.7) = 2.9 in3
Finally:
Volume of the cylinder - volume of the cone = 100.5-2.9 = 97.6 in3
Feel free to ask for more if needed or if you did not understand something.

The length of a new rectangular playing field is 6 yards longer than double the width. If the perimeter of the rectangular playing field
is 312 yards, what are its dimensions?
The width is yards
Answer:
Width of field = 50 yards
Length of Yards = 106 yards
Step-by-step explanation:
Let the width of field be x yards
given that "The length of a new rectangular playing field is 6 yards longer than double the width"
Length of Yards= 2*width of field + 6 = 2x+6 yards
perimeter of the rectangular playing field = 312 yards
We know that perimeter of rectangle is given by 2(length + width ).
Since field is rectangular then
2(length + width ) = 312
2(x+2x+6) = 312
=> 3x+6 = 312/2 = 156
=> 3x = 156 - 6 = 150
=> x = 150/3 = 50
Thus,
Width of field is x = 50 yards
Length of Yards= 2x+6 yards = 2*50+6 yards = 106 yards

Express in numbers six and three hundredths
Answer:
6.03
Step-by-step explanation:
'6' would be a whole number. When stating decimals, you would say the whole numbers before 'and'.
For example: 5.6 would be 'five and six tenths'. Note that five is before 'and'.
'Three hundredths' would be .03.
Therefore:
"Six and three hundredths" would be '6.03'.

Find the measure of QPR.. I need full explanation please
Answer:
b) 42°
Step-by-step explanation:
When two triangles share the same base (in this case, side QR), one angle is half of the other one. In this case:
1/2*∠QPR = ∠QSR
From the picture,
∠QSR = 21°
Replacing into the equation and solving for ∠QPR:
∠QPR = 2*21° = 42°

IT IS A CLOCK PROBLEM
What is the angle between the hands at 4:41?
Answer:127.5∘
Step-by-step explanation:
The angle measure between any two consecutive numbers on a clock is 36012=30∘.
Call the "12" point on the clock the zero-degree point.
At 4:45, the minute hand is at the "9" - that is, at the 30×9=270∘ mark. The hour hand is three-fourths of the way from the "4" to the "5; that is,
30×434=142.5∘ mark.
Therefore, the angle between the hands is
270−142.5=127.5∘, the desired measure.

What is the name of the point that you use to define a parabola?
A. Vertex
B. Center
C. Focus
D. Directrix
sig
Answer:
C
Step-by-step explanation:
A parabola is set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola and the line is called the directrix.
Focus is the name of the point that you use to define a parabola
What is Parabola?A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped
A parabola is a symmetrical U-shaped curve that can be defined as the set of all points that are equidistant to a fixed point (called the focus) and a fixed line (called the directrix).
The vertex is the point where the parabola changes direction and is located halfway between the focus and the directrix.
The center is a term used to refer to the midpoint of the line segment connecting the two foci of an ellipse or hyperbola, and is not relevant to a parabola.
Hence, Focus is the name of the point that you use to define a parabola
