An item is regularly priced at $80 Barbado add a discount of 25% off the regular price how much did Bob pay
Answer: $60
Step-by-step explanation:
Given
The price of an item is $80
The discount on it is 25%
Net payable price =Regular Price- discount
[tex]\Rightarrow \text{Net Payable Price(P)}=80-25\%\ \text{of}\ 80\\\Rightarrow P=80(1-0.25)=80\times 0.75\\\Rightarrow P=\$60[/tex]

Tell whether the lines through the given points are parallelperpendicular, or neither Line 1: (1, 0), (7, 4) Line 2: (7, 0) , (3, 6) The slope of line 1 is The slope of line 2 is
Answer:
The lines are perpendicularStep-by-step explanation:
We determine whether lines are parallel or perpendicular by getting their slopes
For line 1; (1, 0), (7, 4)
Slope m = 4-0/7-1
M1 = 4/6
M1 = 2/3
Hence the slope of M1 is 2/3
For Line 2; (7, 0) , (3, 6)
M2 = 6-0/3-7
M2 = 6/-4
M2 = -3/2
Take the product of the slopes
M1 * M2 = 2/3 * -3/2
M1M2 = -1
Since the product of their slope is -1, hence the lines are perpendicular

Solve 3x - y = 3 and 2x - y = 2 by substitution method
Answer:
x = 1
y = 0
Step-by-step explanation:
3x - y = 3
2x - y = 2 , then y = 2x - 2
substitute for y:
3x - (2x - 2) = 3
combine like terms:
x + 2 = 3
subtract 2 from both sides of the equation:
x = 1
y = 2(1) - 2 = 0
Answer:
x=5, y=8
Step-by-step explanation:
let 3x-y=3 be [1]
and 2x-y = 2 be [2]
Change up [2] to:
2x=2+y
2x-2 = y and name this [3]
Sub [3] into [1]
3x-(2x-2)=3
3x-2x-2=3
x-2=3
x=5
Sub x=5 into [3]
2(5)-2=y
10-2=y

Make circle open
You have the right idea but the endpoint is at the wrong location. Instead, the green dot should go at -1. The shading is to the right. We use a closed filled in circle here (instead of an open hole) to tell the reader "include the endpoint". So -1 is part of the solution set.
In short, the graph consists of a closed filled in circle at -1 with shading to the right. This visually describes all values that are larger than -1, or equal to -1.

What is the scale factor of the dilation from A to B?
Answer:
1
Step-by-step explanation:
The scale factor of the dilation from A to B is, 1.67
What is the scale factor ?Scale factor is a mathematical term, which we use to scale 2-dimensional and 3-dimensional shapes. Scale factor is a measure of similar figures. Those figures who look the same but are in different sizes.
For example, Two spheres look similar but could have different radii.
Given that,
Two parallelograms
A & B
First one has side length = 4.5 unit
Second one has side length = 7.5 unit
For calculating scale factor, we need to found ratio of two sides length
Scale factor = 7.5/4.5
= 1.66666
Hence, the scale factor is 1.67

4. Asia is designing a triangular-shaped window with a height of 15 inches and
an area of 135 square inches. What is the length of the base of the window?
Answer:
18in
Step-by-step explanation:
Given data
Height h= 15 in
Area= 135 in^2
The expression for the area is given as
Area= 1/2 Base * Height
substitute
135= 1/2* Base*15
135= 7.5 Base
Base= 135/7.5
Base= 18 in
Hence the base is 18in
Jess has 60 ounces of an alloy that is 40% gold. How many ounces of pure gold must be added to this alloy to create a new alloy that is 75% gold?
Answer:
84 ounces of pure gold
Step-by-step explanation:
Jess has 60 ounces of an alloy that is 40% gold. How many ounces of pure gold must be added to this alloy to create a new alloy that is 75% gold?
Pure gold = 100% gold
Let the number of ounces of pure gold = x
Hence, we have the equation
40% × 60 ounces + 100%× x ounces = 75%(60 + x)ounces
= 0.4 × 60 + 1x = 0.75(60 + x)
= 24 + x = 45 + 0.75x
Collect like terms
x - 0.75x = 45 - 24
0.25x = 21
x = 21/0.25
x = 84 ounces
Therefore, we need 84 ounces of pure gold
84 ounces of pure gold must be added
The first is to write out the parameters
Jess has 60 ounces of alloy
40% of this alloy is pure gold
The number of ounces that should be added can be calculated as follows;
Let y represent the unknown
40/100(y)(60) + 100/100(y)= 75/100(60+y)
24 + y= 0.75(60+y)
25 + y= 45 + 0.75y
24 - 45= 0.75y -y
-21= -0.25y
y= 21/0.25
y= 84
Hence the number of ounces of pure gold required is 84 ounces

Answer:
Not sure about the question but I believe you are looking for the length of AC.
Then the answer is choice 3) 13
Step-by-step explanation:
AC² = 5² + 12² = 25 + 144 = 169
AC =√169 = 13
The required length from the point outside the circle to the point on the circle i.e. CE is 8 and the length from the point outside the circle to the center is 13.
The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
where h, k is the coordinate of the center of the circle on coordinate plane and r is the radius of the circle.
Here,
C is the point outside the circle and tangent drawn to the circle from C to B of length 12, the radius of the circle is 5. Since the radius is always perpendicular to the circle's tangent,
So
ABC is right angle triangle
AB = 5 ; BC = 12
Now applying the Pythagorean theorem
AC² = AB² + BC²
AC = √(5² + 12²)
Ac = √(25+144)
AC = √169
AC = 13
Now,
AC = AE + EC
(AE = AB)
AC = AB + EC
13 = 5 + EC
EC = 8
Thus, the required length from the point outside the circle to the point on the circle i.e. CE is 8 and the length from the point outside the circle to the center is 13.
