Answer number 1 plsssss
Answer:
At Z-Mart, after the discount it is 7/8 of the original price of 225,
at ABC Sports the final price is 200,
and at Bike World, after the discount it is 3/4 of the original price of 265
so
we multiply 225 by 7/8 to get 196.88,
which is lower than ABC Sports,
and then we multiply 265 by 3/4 to get 198.75, which is higher than Z-Mart
so Z-Mart or A) is correct.
Hope this helps! :D

Given function:
g(x) = x² - 6x + ca)
c = 2Th x-intercept found when g(x) = 0
x² - 6x + 2 = 0Solve the equation to find the values of x:
x² - 6x + 2 = 0x² - 6x + 9 = 7(x - 3)² = 7x - 3 = ±√7x = 3 ± √7The x-intercepts are (3 + √7, 0) and (3 - √7, 0)
b)
c = 10Solve as above:
x² - 6x + 10 = 0x² - 6x + 9 + 1 = 0(x - 3)² = -1The left side is a square of a number which is always positive, the right side is negative.
It means there is no solution, so no-x-intercepts.
The graph of the function lies above the x-axis.

If AB = 24 inches and AB is dilated by a scale factor of
3
5, find A'B'.
Answer:
72in
Step-by-step explanation:
If AB = 24 inches and AB is dilated by a scale factor of 3, then A'B' is gotten by multiplying the AB by the sclae factor as shown;
A'B' = 3AB
A'B' = 3(24)
A'B' = 72 in
Hence the length of A'B' is 72in

Find the length of midsegment JN in the trapezoid.
Answer:
JN = 18.6
Step-by-step explanation:
Theorem: The length of the midsegment of a trapezoid is the average of the bases.
[tex]JN = \frac{15.4 + 21.8}{2}[/tex]
[tex]= \frac{37.2}{2}[/tex]
= 18.6

The equation y=100x represents the distance y in kilometers that a car can travel in x hours. Determine whether there is a constant of variation. If so, explain what it represents in this situation
Answer:
100
Step-by-step explanation:
Give the equation :
y = 100x
The equation above is expressed using the general formof a direct variation ; where ;
a varies directly as x equals
a = kx
Where, k = constant of proportionality
Comparing this with the equation above, we can conclude that, the above equation has a constant of variation, k which is equal to 100

Given a roll of nickels. The diameter of one nickel is 0.835 inches, and the thickness is 0.077 inches. Find the surface area of a roll of $2 in nickels. Round to the nearest tenth.
PLS RESPOND ASAP I NEED THE ANSWER PLSSSS
Answer:
124.8 Inches
Step-By-Step
1/2 0.835 Inches = 0.4175
r = 0.4175
h = 0.077
A=2πrh+2πr^2
A=2π(0.4175)(0.077)+2π(0.4175^2)
A = 3.12
Nickel = 5 Cents
$2 = 200 Cents
200 / 5 = 40
(3.12)(40) = 124.8 In
Answer:
The answer is 0.8 in^2
Step-by-step explanation:
Data
diameter = 0.835 in
thickness = 0.077in
Roll of $ 2.00
Procedure
1.- Find the total number of nickels
# of nickels = 2/ 0.05
# of nickels = 40
2.- Calculate the Circumference
C = 2*pi*r
r = 0.077/2
r = 0.0385
C = 2*3.14*0.0385
C = 0.242 in
3.- Calculate the area of the thickness
Area = 0.242* 0.077*40
Area = 0.745 in^2
4.- Calculate the area of the base and the top
Area = 2*pi*r^2
Area = 2*3.14*(0.0382)^2
Area = 0.0093 in^2
5.- Calculate the total area of the roll
Total area = Area of the thickness + Area of the base and top
Total area = 0.745 + 0.0093
Total area = 0.7543 in^2 This is the result
Rounding to the nearest tenth = 0.8 in^2

Find the circumference and area of a circle to the nearest hundredth. Use 3.14 for pie. Round to the nearest hundredth if necessary. The diameter is 52.
Answer:
Circumference = 163.28 unitsArea = 2,122.64 units²Step-by-step explanation:
Circumference
Circumference of a circle is calculated by the formula:
= π * diameter
= 3.14 * 52
= 163.28 units
Area
Area of a circle is calculated by the formula:
= π * radius²
Radius = DIameter / 2
= 52 / 2
= 26 units
Area = 3.14 * 26 * 26
= 2,122.64 units²

Answer How many solutions does the nonlinear system of equations graphed below have?
Look at the number of points where the graphs intersect each other...the points where the graphs of the functions cross each other are the solutions to the system.
Upon looking, you should see 4 points where the graphs intersect, so there are 4 solutions to the non-linear system of equations.

Step-by-step explanation:
use y = mx + b
m = slope = rise/run = 2/5
b = y-intercept when x is zero (0,y) = (0,2) = 2
since the line is going down, the slope has to be negative.

Answer:
Given that is a 45-45 triangle, the hypotenuse should be x[tex]\sqrt{2}[/tex], so in this case. The hypotenuse should be 3[tex]\sqrt{2}[/tex], and the other side lengths 3. I see no other way of it going other than that one; I hope I helped at least a bit!
Step-by-step explanation:
Answer:
base =3in and hypotenuse =3√2
Step-by-step explanation:
relationship between perpendicular and hypotenuse is given by sin angle
sin 45=p/h
sin45=3in/h
h=3in/sin45=3√2 inch
relationship between perpendicular and base is given by tan angle
tan45=P/b
b=3in/tan45=3in
