the camera cost $540 if the sales tax is 7.2% what is the tax change and the total cost?
Answer:
38.88
Step-by-step explanation:
Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
Angle t= 37 degrees angle u=? Angle v= 63
Answer:
[tex]m <U = 80°[/tex]
Step-by-step explanation:
Before we start calculating we have to first note that the angles in a triangle always add up to 180°. Therefore in order to find the missing angle U we have to add both the angles we know, 37° and 63°, then subtract the sum from 180°
[tex]m < U = 180- (37 + 63) \\ \\ m < U = 180 - 100 \\ \\ m< U = 80[/tex]

Hello!
First let's isolate y:
y + 21 > 6y > -15This means that we are looking at all the values on the coordinate plane that are above the line y = -15.
The red shaded region is the solution region. Note that -15 is not a solution of y > -15 (the dotted line indicates that).

Suppose that there are two types of tickets to a show: advance and same-day. Advance tickets cost $30 and same-day tickets cost $15. For one performance, there were 65 tickets sold in all, and the total amount paid for them was $1500 . How many tickets of each type were sold?
The advance tickets were 35 in number and the same day ticket will be 30 in number.
What will be the number of tickets?To find out the number of the tickets sold we will give some notations so the notations are as follows:-
A= Cost of advance tickets=$30
S= cost of same-day ticket-=15
[tex]N_A=[/tex] Number of the advance tickets
[tex]N_S=[/tex]Number of same-day tickets.
The equations made by the given data will be:-

What is a normal distribution?The Gaussian Distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.
In a particular region, for families with a combined income of $80,000 or more, 20% have no children, 30% have one child, 40% have two children, and 10% have three children.
Let x be the number of children per family.
We have to construct a probability distribution for x from the given information.
x = 0, 1, 2, 3
For x = 0, the probability will be
P(x) = 20 / 100 = 0.20
For x = 1, the probability will be
P(x) = 30 / 100 = 0.30
For x = 2, the probability will be
P(x) = 40 / 100 = 0.40
For x = 2, the probability will be
P(x) = 10 / 100 = 0.10

The sign of a times -b/b when a = 0 and b < 0 is neutral neither negative nor positive .
What is a integers ?An integer is a whole number (not a fractional number) that can be positive, negative, or zero
As b<0 which means b would be negative.
So, -b/b gives a negative value.
Because if any of the either numerator or denominator is negative then the resulting value also be negative.
and if zero '0' is multiplied and number whether it is positive or negative the resulting value will be zero.
So, a* (-b/b)= 0* negative= negative zero, but zero is neither negative nor positive .

Answer:
sin(t) = 4*sqrt(5) / 21; cos(-t) = 19/21
Step-by-step explanation:
think of a right triangle with an adjacent leg a, opposite leg b, and hypotenuse c.
cos(t) = a/c = 19/21. so we can assume a=19 and c=21.
using Pythagorean's theorem, find b: b = sqrt(21^2 - 19^2) = 4*sqrt(5) or 8.944
since tan(t)> 0, b/a > 0 and a is positive so b must be positive. using this information, we know sin(t) = b/c = 8.944/21 or 4* sqrt(5) / 21
since cos x is an even function, cos(-x) = cos x so cos(-t) = cos(t) = 19/21
