Answer:
Ben's number was [tex]\frac{3}{2}[/tex].
Step-by-step explanation:
Given that:
Ben thinks of a number.
Let,
x be that number.
According to given statement;
Double of number plus 4 is equals to number multiplied by 10 and subtracting 8.
2x + 4 = (x*10) - 8
2x + 4 = 10x - 8
4 + 8 = 10x - 2x
12 = 8x
8x = 12
Dividing both sides by 8
[tex]\frac{8x}{8}=\frac{12}{8}\\x=\frac{3}{2}[/tex]
Hence,
Ben's number was [tex]\frac{3}{2}[/tex].

Paul was plotting points on a graph. He was given (3,4). When he moves 3 spaces, which direction will he need to go?
Answer:
right from the y-axis
Step-by-step explanation:
The ordered pair (3, 4) is understood to be the (x, y) coordinates of the point Paul wants to plot.
__
The x-coordinate (3) is the number of spaces the point lies to the right of the y-axis.
The y-coordinate (4) is the number of spaces the point lies above the x-axis.
__
If Paul is moving 3 spaces from the y-axis, he will be moving to the right to get to where he will plot the point.

Short Explanation:
Subtract the arcs and divide by 2 like so
angle 1 = (longerArc - shorterArc)/2
angle 1 = (100 - 30)/2
angle 1 = 70/2
angle 1 = 35 degrees
---------------------------
Longer explanation:
Refer to the diagram below. I have replaced the 100 and 30 degree arcs with A and B respectively. I've also added in the arc measures of y and z.
Note how the smaller circle arc pieces A, B, y and z all form a complete full circle. So those values add to 360. We get A+B+y+z = 360. We'll use this later.
In the diagram, I've also drawn a blue segment to form a triangle. The angle x we want to find has replaced angle 1. The angles (y+B)/2 and (z+B)/2 are found through the inscribed angle theorem.
Focus on the triangle. The three angles of any triangle always add to 180, so,
(z+B)/2 + (y+B)/2 + x = 180
we can multiply both sides by 2 and we end up with
z+B + y+B + 2x = 360
z+y+2B + 2x = 360
Since we have 360 on the right hand side of this equation, and the equation A+B+y+z = 360, this means that the left sides of each equation are the same.
We can then say the following
z+y+2B + 2x = A+B+y+z
2B+2x = A+B
2x = A+B-2B
2x = A-B
x = (A-B)/2
This is the formula used in the "short explanation" section above. In this case, A = 100 and B = 30, so
x = (A-B)/2
x = (100-30)/2
x = 70/2
x = 35
The measure of angle 1 is 35 degrees.
Side note: With that formula above, we always have A > B.
Answer:
[tex]m\angle 1 = 35^\circ[/tex]
Step-by-step explanation:
Exterior Angle of a Circle
An exterior angle of a circle is an angle whose vertex is outside a circle and the sides of the angle are secants or tangents of the circle.
Please refer to the figure below.
The measure of the exterior angle x is given by:
[tex]\displaystyle x=\frac{b-a}{2}[/tex]
Where a and b are the intercepted arcs.
We are given b=100° and a=30°, thus angle 1 is:
[tex]\displaystyle m\angle a=\frac{100°-30°}{2}[/tex]
[tex]\boxed{m\angle 1 = 35^\circ}[/tex]

Busby County is rectangular. A map of the county on a coordinate plane shows the vertices of the county
at A(-4, 6), B (6,6), C (6,-9), and Di-4,-9). Each unit on the map represents 1 mile.
What is the county's perimeter?
Answer:
The county's perimeter is of 50 miles.
Step-by-step explanation:
Perimeter of a rectangle:
The perimeter of a rectangle, with length l and width w, is given by:
[tex]P = 2(l + w)[/tex]
Length:
Segments AB and CD.
The length is 6 - (-4) = 6 + 4 = 10 units = 10 miles.
Width:
Segments BC and AD.
The length is 6 - (-9) = 6 + 9 = 15 units = 15 miles.
Perimeter:
[tex]P = 2(10 + 15) = 2(25) = 50[/tex]
The county's perimeter is of 50 miles.
Write an equation that represents the line passing through the point -3, -1 with a slope of 4
Answer:
Equation that represents the line passing through the point -3, -1 with a slope of 4 is
[tex]y= 4x+11[/tex]
Step-by-step explanation:
Equation of line in point slope form is
[tex]y-y_1=m(x-x_1)[/tex] -------(1)
Here
[tex]m=4 \ \ \ and \ \ \ (x_1, y_1) = (-3, -1)[/tex]
Substituting values in equation (1)
[tex]y+1=4(x+3)\\ y= 4x+11[/tex]

Answer: 8
Step-by-step explanation: Look at the first digit after the decimal point, if it is less than 5 than you do not have to do anything. In this case, it is less than five so it is closer to zero, which is why we count it and all the numbers behind it like a zero. It does not work that way for some problems! Hope this helps!

Answer and Step-by-step explanation:
-2 + 23x is an angle, and since the angles are all 90 degrees (shown with the red square), -2 + 23x = 90
Solve for x.
-2 + 23x = 90
Add 2 to both sides.
23x = 92
Now divide by 23 on both sides to obtain x.
x = 4
x is equal to 4.

Please urgent fast thanks
Answer:
A) I = $171.73
B) $4771.73
Step-by-step explanation:
We are told her loan is $4600 for 7 months.
Thus;
Principal; P = 4600
Time; T = 7 months = 7/12 year
Interest rate is given as 6.4%
Thus; r = 6.4
A) To get the interest, the Formula is;
I = PRT/100
I = (4600 × 6.4 × (7/12))/100
I = $171.73
B) Since interest is $171.73, it means amount she owes after the 7 months = $4600 + $171.73 = $4771.73

He receives 6.5% per year simple interest.
How much will Brian have after 5 years?

Step-by-step explanation:
The formula for the balance of a simple-interest account is ...
A = P(1 +rt) . . . . P is the amount invested, r is the annual rate, t is years
A = £13400(1 + 0.065(5)) = £13400(1.325) = £17,755
