George bought a model of a Viking ship for $68. If he paid
$5.10 in sales tax, what was the sales tax rate?
Answer:
We can convert 6.75% to a decimal by dividing by 100.
If x is the price of the house, then the sales tax is 0.0675x. The price of the house and the sales tax add up to $319,000.
x+0.0675x=319,000
Combe terms on the left.
1.0675x=319,000
Finally, divide both sides by 1.0675.
x=319,0001.0675=298,829.04

what is the input of arccos
Answer:
It returns the angle whose cosine is a given number.
Step-by-step explanation:
For every trigonometry function, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. (On some calculators the arccos button may be labeled arccos, or sometimes cos-1.) So the inverse of cos is arccos etc. When we see "arccos x", we understand it as "the angle whose cosine is x"
cos30 = 0.866 Means: The cosine of 30 degrees is 0.866
arccos 0.866 = 30 Means: The angle whose cosine is 0.866 is 30 degrees.
Use arccos when you know the cosine of an angle and want to know the actual angle.

The diagonals of a quadrilateral are 12 and 10. Is
this a parallelogram rectangle? Explain your answer
Answer:
the answer is no.a parallelogram is not a rectangular but the opposite is true. the reason is a cause of parallelogram's diagonals.they might not be equal in parallelogram but in rectangular they must be equal.
Step-by-step explanation:
Answer:
If both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram. So yes it is a parallelogram.
Step-by-step explanation:
Diagonals of parallelogram are not necessarily equal. This is a known property of a parallelogram. If all angles are equal, then it means its opposite angles are also equal which is a condition for a quadrilateral to be called parallelogram. If all sides are equal then, opposite sides are also equal.

H. p = 13c + 75
100
J. c = 13p + 75
Answer:
The answer is j
Step-by-step explanation:
The equations shows the relationship between c and p is p= 13c + 75.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have table which shows amount that a catering company charges based on the number of people at an event.
So, the equation that can framed from the table as
(y- 400)= (725- 400) / (50-25) . (x-25)
y- 400 = (325/ 25) (x-25)
y-400 = 13(x-25)
y-400 = 13x - 325
y = 13x - 325 + 400
y= 13x + 75
or p = 13c+ 75

To get 3 heads, means that one gets only one tail. This tail can be either the 1st coin, the 2nd coin, the 3rd, or the 4th coin. There are only 4 outcomes which have three heads....hope this helped
Dalton built a linear model to show the height of a meteor falling to the Earth. The meteor starts at 100 km above the Earth's surface and falls at a rate of 20km per second. The x values represent the time in seconds and the y values represent the height of the meteor. What does the domain represent in context of the model?
Answer:
The domain represents the time of motion of the meteor as it falls from 100 km height above the Earth's surface at a speed of 20 km
Step-by-step explanation:
The given parameters from the question are;
The elevation of the meteor above the Earth's surface = 100 km
The rate at which the meteor falls = 20 km per second
The 'x' values represent the time in seconds and the 'y' values represent the meteor's height
Therefore, we have;
y = 100 - 20·x
The domain of a function is the set of inputs to the function
Therefore, the domain represent the time it takes the meteor to reach the given 100 km height above the Earth's surface
At the start x = 0 seconds
On the Earth's surface, y = 0, therefore;
0 = 100 - 20·x
x = 100/20 = 5
When the meteor just touches the Earth's surface x = 5 seconds
Therefore, the domain is 0 ≤ x ≤ 5.
Which is a solution of 2x(8x + 5) (7x – 13) = 0?
Answer:
Step-by-step explanation:
This has 3 solutions
2x = 0 Divide by 2
x = 0
8x + 5 = 0 Subtract 5 from both sides
8x = - 5 Divide by 8
x = - 5/8
x = -0.625
7x - 13 = 0 Add 13 to both sides
7x = 13 Divide by 7
x = 13/7
x = 1.86

In a polling station, there were 900 registered voters. During an election 10% of the registered voters did not cast their votes. The rest cast their votes to Ahmed, Babu and Chambuko in the ratio 3:2:1.If 30 votes were spoilt,how many votes did Ahmed get?
Answer:
Ahmed got 390 votes
Step-by-step explanation:
Here, we want to know the number of votes obtained by Ahmed
from the question, there were 900 registered voters
10% did not cast their votes
The number that didn’t cast their votes will be;
10% of 900
= 10/100 * 900 = 90
So the rest 90% casted and this value will be 900-90 = 810
810 people casted their votes
30 votes were spoilt;
The number of valid votes is thus;
810 - 30 = 780
Ahmed got a ratio of 3 in 3:2:1
The total value here is 3 + 2 + 1 = 6
So what Ahmed got will be;
3/6 * 780
= 780/2 = 390

Find the value of x.
Answer:
x = 30°
Step-by-step explanation:
< A = 90° {Being vertically opposite angles }
Now
x + 90° + 2x = 180° (Being linear pair)
3x = 180° - 90°
3x = 90°
x = 90° / 3
x = 30°
