A snowboard was $180 but marked as 30% off. There is a state tax of 7.5%. How much would you pay for the snowboard
Answer:
180(.30)=54, 180-54=126, 126(0.075)=9.45+126=135.45
Step-by-step explanation:
The total is $135.45.
Answer:$135.45
Step-by-step explanation:
180X .30 = 54 dollars off
180-54 =126 so the board on sales costs $126
Adding the tax
126x.075 = 9.45 is the tax due
126+9.45 = 135.45

Renee bought 7 potatoes at the supermarket. The shortest diameter of each, in centimeters, is shown below. 2,3,,4,4 6,6,7 After Renee used one potato to make dinner, the median diameter of the remaining potatoes was 5 centimeters. Which of these could be the diameter, in centimeters, of the potato Renee used?
Answer:
2 cm, 3 cm or 4 cmStep-by-step explanation:
Diameters of potatoes:
2, 3, 4, 4, 6, 6, 7Median is:
4 cmAfter one potato used the median becomes 5 cm.
Out of 6 potatoes left, the two in the middle should give 5 cm in average
This is 4 cm and 6 cm.
Renee must have used one of the 4 potatoes on the left: 2 cm, 3 cm or 4 cm

Do you agree with the rules of the council on tall buildings and urban habitat regarding spires and antennae? Are the Petronas towers really taller than the Sears tower?
Answer:
Yes, I agree
The Petronas Towers are taller than the Sears tower
Step-by-step explanation:
The rule regarding spires and antenna of the Council on tall buildings and Urban Habitat states that "an antenna is just functional - something with a technical purpose stuck on the top of a building after it is finished while spires are considered a continuation of the form of the building.
According to the Council, the Petronas Towers are taller than the Sears Tower because spires are included in a building's architecture while antennae are not.
The architectural height of the Petronas towers is 1,483ft
The architectural height of the Sears (now Willis) tower is 1,450ft

4r + 10 = -26
What is the answer
Answer:
r = - 9
Step-by-step explanation:
Given
4r + 10 = - 26 ( subtract 10 from both sides )
4r = - 36 ( divide both sides by 4 )
r = - 9

Find the measure of angle A
Answer:
30
Step-by-step explanation:
(x + 37) + (x + 67) + 90 = 180 by the Triangle Angle Sum Theorem
(x + 37) + (x + 67) = 90
2x + 104 = 90
2x = -14
x = -7
(-7 + 37) = angle A
angle A = 30
Answer:
<a = 30
Step-by-step explanation:
x + 37 + x + 67 + 90 = 180
<A + <B + <C = 180
*take each angle, add them, and equal them to 180*
x + 37 + x + 67 + 90 = 180
*solve for x*
2x + 194 = 180
-194 -194
2x = -14
x = -7
<a = x + 37
<a = (-7) + 37
<a = 30
<b = x + 67
<b = (-7) + 67
<b = 60
<c = 90

A person invests 9000 dollars in a bank. The
bank pays 6.5% interest compounded daily.
To the nearest tenth of a year, how long
must the person leave the money in the bank
until it reaches 31100 dollars?
Answer:
19 years approx
Step-by-step explanation:
Given dta
P= $9000
r= 6.5%
A= $31100
Calculate time, solve for t
t = ln(A/P) / r
substitute
t= ln(31100/9000)/0.06.5
t= ln(3.45)/0.06.5
t= 1.23/ 0.065
t= 18.92
Hence the time is 19 years approx

Assume that lines that appear to be tangent are tangent. O is the center of the circle. What is the value of x?
9514 1404 393
Answer:
x = 20, or 125
Step-by-step explanation:
We cannot tell the angle x is intended to refer to. So, here are two answers. Choose the one you think applies.
__
The triangle that includes both marked angles is a right triangle. (The tangent meets the circle at right angles to the radius.) So, the angle x° at the external point is the complement of the marked central angle.
x° = 90° -70°
x = 20
__
If x° is referring to the exterior angle associated with the isosceles triangle within the circle, then its measure is the supplement of the interior base angle of that triangle. It is ...
x° = 180° -(180° -70°)/2 = 90° +70°/2
x = 125

In the question, 3 functions in tabulated form is given, we draw the function on the graph then we observe that,
Table A, shows the cubic function because the graph with an increase of x increase and decrease multiple times.
Table B, shows the quadratic function, is shows the curve as of the parabola.
Table C, shows the linear relationship, as it forms a line on the graph.
Thus, tables A, B, and C represent cubic, quadratic, and linear functions respectively.

The membership in the Lego Club decreased from 120 members in August to 82 members in October. What was the percent decrease from August to October?
Type your answer using the % key. Round to the nearest whole percentage if necessary.
Answer:
72% decrease I...guess?
120 members-60 members=50%
-70 should be approx=60%
-80 should be approx=70%
so 80 is around 70%, so I'd say 82 is 72%
I'm most likely wrong but i dunno maybe im right
Step-by-step explanation:
Answer:
32%
Step-by-step explanation:
((120 - 82) / 120) x 100 = 31.66 %

Solve for r.
–6(r − 98) = 78
Answer:
r=85
Let's solve your equation step-by-step:
−6(r−98)=78
Step 1: Simplify both sides of the equation
−6(r−98)=78
(−6)(r)+(−6)(−98)=78(Distribute)
−6r+588=78
Step 2: Subtract 588 from both sides
−6r+588−588=78−588
−6r=−510
Step 3: Divide both sides by -6
−6r/−6=−510/−6
r=85
Answer:
r=85
Answer:
85
Step-by-step explanation:
–6(r − 98) = 78
expand:
-6r+588=78
588-78=510
6r=510
510÷=85
HELP ASAP 3.) Andy's Karpet Kleaning charges a $23 consultation fee, plus $17 per hour to clean carpets. Stanley
Steemer charges a $37 consultation fee, plus $13 per hour. After how many hours will the total charge be the
same? What is the charge?
Answer:
After 3.5 hours and the charge is $82.50.
Step-by-step explanation:
Setting up the equations equal to each other will give a solution (x-value) that makes both sides equal (the same price) after the same amount of hours (x-value).
13x + 37 = 17x +23
x = 3.5
Then plug the hours into either side to get the equal price.
13(3.5) + 37 = $82.50
OR
17(3.5) + 23 = $82.50

A piece of paper is 0.1 millimeter thick. When folded, the paper is twice as thick.
Find both the explicit and recursive rule for this geometric sequence.
Answer:
sorry i am struggling the same
Step-by-step explanation:
2+2=4
The answers to each part are mentioned below.
What is geometric sequence? What is an exponential function? Differentiate between equation and expression? geometric sequence : A geometric sequence is a special type of sequence where the ratio of every two successive terms is a constant. This ratio is known as a common ratio.function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is a piece of paper is 0.1 millimeter thick. When folded, the paper is twice as thick.
We can write the geometric sequence as -
0.1, 0.2, 0.4, 0.8 ......
The explicit formula for a geometric sequence is of the form -a{n} = arⁿ ⁻ ¹
where [r] is the common ratio.
The recursive formula for a geometric sequence is of the form -a{n} = a{n - 1}rFor the geometric sequence -
0.1, 0.2, 0.4, 0.8 ......
The explicit formula will be : a{n} = (0.1)(2)ⁿ ⁻ ¹ The recursive formula will be : a{n} = 2a{n - 1}If the paper is folded 7 times, we can write the thickness as -
y{7} = (0.1)(2)⁶ = (0.1) x (64) = 6.4
To surpass the Mount Everest, we can write -
8850 < (0.1)(2)ⁿ ⁻ ¹
(2)ⁿ ⁻ ¹ > 88500
(2)ⁿ/2 > 88500
(2)ⁿ > 177000
n log(2) > log(177000)
n > {5.25/log(2)}
n > 17.44
n > 18

look at the graph of a line and write its equation
Answer:
y=-2/3x-1
Step-by-step explanation:
You can fins the slope (or the m in y=mx+b) by counting how many units up/down and over it takes to get to another solid point and configuring it into a fraction rise/run. in this case you go down 2 units and over 3 units to get -2/3
to get the y-intercept (the b in y=mx+b) you look at where the lince intercepts the y-axis in this case it is at -1

What is the equation of a line with a gradient of 2 that passes through (0,5)?
9514 1404 393
Answer:
y = 2x +5
Step-by-step explanation:
"Gradient" is another word for "slope." The given point (with x-coordinate equal to zero) is the y-intercept. So, it is easy to write the equation in slope-intercept form:
y = mx + b . . . . . . line with slope m and y-intercept b
y = 2x + 5
