Answer:
The number would be 90
Step-by-step explanation:
140 + 10 - 90 = 60
90 - 30 = 60
60 = 60
Answer: 90
Step-by-step explanation:
Let's use x as a placeholder to the number we are trying to find
[tex]140+10-x=x-30[/tex]
Now we need to isolate x
Step 1) Simplify both sides
[tex]140+10-x=x-30\\150-x=x-30[/tex]
Step 2) Add 30 to both sides
[tex]150-x+30=x-30+30\\180-x=x[/tex]
Step 3) Add x to both sides
[tex]180-x+x=x+x\\180=2x[/tex]
Step 4) Divide both sides by 2
[tex]\frac{180}{2}=\frac{2x}{2} \\90=x[/tex]
Step 5) Sub our value into the original equation and solve
[tex]140+10-x=x-30\\140+10-90=90-30\\150-90=60\\60=60[/tex]

Determine the equation of the parabola that opens up, has focus (−2,7), and a focal diameter of 24.
Answer:
[tex] \sf{(x + 2)}^{2} = 24(y -1) [/tex]
Step-by-step explanation:
Given:
focus(h,k)= (−2,7)
Focal Diameter (Latus rectum) = 24
To find:
Equation of parabola= ?
Solution:
Focal Diameter also known as letus rectum is the segment which passes through Focus and intersects the Axis of parabola having end point at the wall of of parabola.
Focal Diameter = 24
[tex]4p = 24 \\ p = \cancel\frac{ 24}{ 4} = 6 \\ \fbox{p = a = 6}[/tex]
Now to find the equation of parabola we need the vertex(h,v).
Vertex is a point on parabola which lies in same axis of symmetry at equidistant from the directrix and Focus and the distance is one fourth of letus rectum.
Now,
[tex] \sf \: (h,v) = (h,k-p) \\ \sf \: (h,v)= (-2,7-6) \\\sf \: \fbox{ (h,v) = (-2,1)}[/tex]
Equation of parabola
[tex]\sf{(x-h)}^{2} = 4a(y - v)[/tex]
Substituting the cordinate of vertex in above equation,
[tex] \sf{(x - (-2)}^{2} = 4 \times ( 6)(y-1 ) \\ \sf{(x + 2)}^{2} = 24(y -1)[/tex]
This is the final answer.

The owner of a food cart sells an average of 60 frozen treats per day during the summer. Which graph best shows the relationship between the number of days and the number of frozen treats sold?
A) A
B) B
C) C
D) D
Answer:
Answer is D
Step-by-step explanation:
Day 1 = 60
Day 2 = 120
Day 3 = 180
Day 4 = 240
Day 5 = 300
Day 6 = 360
Day 7 = 420
Day 8 = 480
The graph D will show the best relationship between the number of days and the number of frozen treats sold.
What is graph?In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.
It is given that he sells 60 frozen treats per day so everyday the frozen treats are multiplied by 60.
We can see the linear relationship between frozen treats and number of days.
Day 1 - 60
Day 2 - 120
Day 3- 180
Day 4- 240
Day 5- 300
Day 6- 360
Day 7- 420
Day 8- 480
Hence the graph D will show the best relationship between the number of days and the number of frozen treats sold.

Zack looks at the clock and sees the hands have made a 90° angle. He realizes he has 2 hours before basketball practice starts. Which could be the angle formed by the hands of the clock when practice starts?
The angle formed by the clock is its degree measure
The angle formed by the hands of the clock when practice starts is 30 degrees
How to determine the possible angle?The current angle is given as:
Angle = 90 degrees
The basketball practice starts at:
Practice = 2 hours earlier
An hour in time represents 30 degrees.
So, the angle formed when the practice starts is
Angle = 90 degrees - 2 * 30 degrees
Evaluate
Angle = 30 degrees
Hence, the angle formed by the hands of the clock when practice starts is 30 degrees

2x + 5 = 21
[tex]2x + 5 = 21[/tex]
Subtract both sides 5
[tex]2x + 5 - 5 = 21 - 5[/tex]
[tex]2x = 16[/tex]
Divide both sides by 2
[tex] \frac{2x}{2} = \frac{16}{2} \\ [/tex]
[tex]x = 8[/tex]
Answer:
8
Step-by-step explanation:
To determine the value of "x", we need to isolate the "x" variable completely. The first step in isolating the variable is to remove the constant on the L.H.S. This can be done by subtracting 5 both sides.
⇒ [tex]2x + 5 = 21[/tex]
⇒ [tex]2x + 5 - 5 = 21 - 5[/tex]
⇒ [tex]2x = 16[/tex]
The last step in isolating the "x" variable is to isolate the cooeficient of x. This can be done by dividing the cooeficient of x both sides.
⇒ [tex]2x = 16[/tex]
[Cooeficient of x is 2]
⇒ [tex]\frac{2x}{2} = \frac{16}{2}[/tex]
⇒ [tex]x = \frac{16}{2} = 8[/tex]
In conclusion, the value of the "x" variable is 8.

Find the slope of the line that is parallel and perpendicular to the following equation.
-4x - 4y = -2
Answer:
Slope of the line that is parallel: -1
Slope of the line that is perpendicular: 1
Step-by-step explanation:
For the parallel line:
Rewrite your equation to slope-intercept form: y = mx + b
y = mx + b
m = slopeb = y-intercept (when x = 0)-4x - 4y = -2 <== add 4x to both sides
+4x +4x
-4y = 4x - 2 <== divide both sides by -4
/-4 /-4
y = -x + 1/2
The slope of the line that is parallel to this line is -1 (invisible 1 in front of x).
For the perpendicular line:
*Perpendicular lines have negative reciprocals*
Steps:
1. Take your original slope (-1)
2. Flip it (-1/1)
3. Change the sign (1)
For a slope of -1, the reciprocal would be: 1
Hope this helps!
Answer:
Parallel line:
-1
Perpendicular line:
1
Step-by-step explanation:
Let's simplify first!
-4x-4y=-2
-4x=-2+4y
4y=-4x+2
y=-x+0.5
For a parallel line, the slope should be the same
Therefore...
Slope=1
For a perpendicular line, the slope should be the negative reciprocal of the original.
Therefore...
Slope=-(-[tex]\frac{1}{1}[/tex])
=1

F(x)=-5x2+8x+88
F(x)=-5x2-40-72
F(x)=-5x2+8x+24

Step-by-step explanation:
-5(x + 4)² + 8 = -5(x² + 8x + 16) + 8 =

Five years ago, Julie was 4 feet 7 inches tall. Her sister Carrie was 5 feet 1
tall. Since then, Carrie has grown 2 inches each year. Julie grew 13 inches
during the last 5 years. How much taller than Julie is Carrie now?
The differnce in the height of Carrie and Julie given their rate of growth is 3 inches.
What is the difference in height?Carrie's height = 5 feet 1 inch + (2 x 5)
= 5 feet 1 inch + 10 inches
5 feet 11 inches
Julie's height = 4 feet 7 inches + 13 inches
4 feet 20 inches
Difference in height = 5 feet 11 inches - 4 feet 20 inches
I feet = 12 inches
71 inches - 68 inches
3 inches

These shapes are mathematically similar as line BR and QC are parallel.
To find the scale factor:
First we find the length of BD by adding 26 and 39:
26+39 = 65
So to get from BD to BQ :
We multiply by :
26/65 = 0.4
So to get from RD to CD:
We do
18÷0.4 = 45
Then we subtract 18 from 45 to get x:
45-18 = 27
Therefore the value of x is 27
