write an equation of the line that passes through the given points (3,1) (0,10)
Answer:
y = -3x + 10
Step-by-step explanation:
10-1/0-3 = -3
y = -3x + b
1 = -3(3) + b
1 = -9 + b
10 = b
check your answer:
10 = -3(0) + 10
10 = 10
b should be 10
find a, b and c such that the number a , 7,b,23,c are in A.P please solve it
Answer:
since a,7,b,23,c are in A.P.
first term t1=a
second term t2=7
common difference (d)=7-a
forth term t4=a+3d
23=a+3(7-a)
23=a+21-3a
23=21-2a
2a=21-23
a=-2/2=-1
common difference =7-a=7--1=8
third term =a+2d=-1+2×8=15
:.b=15
5th term =c
a+4d=c
c=-1+4×8=31
a=-1
b=15
c=31

Hiking boots cost $108.35. There is a 7.25% sales tax. What is the total cost of the boots?
Answer:
Hope this helps!
Step-by-step explanation:
How the sales tax calculator works
Step 1: take the total price and divide it by one plus the tax rate.
Step 2: multiply the result from step one by the tax rate to get the dollars of tax.
Step 3: subtract the dollars of tax from step 2 from the total price.
Pre-Tax Price = TP – [(TP / (1 + r) x r]
TP = Total Price.
Answer: $116.21
Step-by-step explanation:
$108.35 + $7.86(tax) = $116.21

A grocery store offers a service where customers can place an order and have their groceries delivered to their home for a additional fee. The equation y=1.5x can be used to find y, the total cost in dollars for x, the grocery cost In dollars. Ian has groceries delivered for a total cost of &125.90. He says his grocery cost must be $118.90. Is Ian correct? Explain your reasoning
Answer:
The answer is below
Step-by-step explanation:
A linear function graph can be represented by:
y = mx + b; where m is the slope and b is the y intercept, x is the independent variable and y is the dependent variable.
Given that y represents the total cost, x represent the grocery cost and the equation is given as:
y = 1.5x
The groceries where delivered for a total cost of $125.90, The grocery cot can be gotten by substituting y = 125.9 and calculating x. Hence:
125.9 = 1.5x
x = 125.9/1,5
x = $83.93
Therefore saying that the grocery cost must be $118.90 is incorrect.

the plane of a room is shown in the picture. the scale is 2 inches: 6 feet. what is the actual length of the room?
what is the actual width of the room? what is the actual area of the room?
Since 2 inches = 6 ft and length of room in the place = 7 inches,
(2x3.5) inches = 6x3.5 ft
7 inches = 21ft
Actual Length of Room = 21 ft.
Width of Room in plane = 3 inches
(2x1.5) inches = 6 x 1.5 ft
= 9 ft
Actual Length of Rook = 9 ft.
Actual Area of Room = Actual Length of Room x Actual Width of Room = 21 x 9 = 189 ft^2

a long distance phone charge of $1.40 for 10 min or 4.50 for 45 min. which is better
Answer: $4.50 for 45min is better.
Step-by-step explanation:
The fee per min for phone charge of $1.40 for 10 min: 1.40/10 = $0.14/min
The fee per min for phone charge of $4.50 for 45 min: 4.50/45 = $0.1/min
$0.14/ min > $0.1/min
4.50 for 45min is better.
What is the measure of arc PQ
Answer:
x = 15
arc PQ = 110°
ΔPQR is an acute triangle
Step-by-step explanation:
(6x) + (8x-10) + (10x+10) = 360°
combine like terms:
24x = 360°
x = 15
arc PQ = 8(15) - 10° = 110°
Answer:
x=15
measure of arc PQ is 110 degrees
Step-by-step explanation:
Hello There!
Remember the circumference of a circle is 360 degrees
So to find x we use the equation
360=8x-10+6x+10x+10
now we solve for x
combine like terms
-10+10 cancels out
8x+6x+10x=24x
now we have
24x=360
divide each side by 24
24x/24=x
360/24=15
we´re left with x = 15
Now lets find the measure of arc PQ
to do so we plug in 15 into x for 8(15)-10
8*15=120
120-10=110
so the measure of arc PQ is 110
