Answer:
(A) 33.9 (B) 22.6
Step-by-step explanation:
We first need to round to the nearest dollar for both prices. Lets examine both numbers.
$30.12 $19.93
We can round $30.12 to $30 since the number in the tenths place is 1 and we can round $19.93 to $20 since there is a nine in the tenths place.
Now we must find the tax for each number. We can do that by multiplying each number by 0.13 since that is 13% in decimal form. Lets do that now
[tex]30*0.13=3.9[/tex] [tex]20*0.13=2.6[/tex]
Now we can find the final price for each number by adding the tax to the rounded price.
[tex]30+3.9=33.9[/tex] [tex]20+2.6=22.6[/tex]
Hence, (A) 33.9, (B) 22.6

television has a normal price of 675
in a sale, the price is reduced by 32%
work out the price of the television in the sale
Answers
Answer:
$459
Step-by-step explanation:
Given the following question:
32% of 675
To find the answer to this question we need to use the formula to calculate 32% of 675. Then we subtract that answer from our original price which will then give us our answer.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{32\times 675}{100}[/tex]
[tex]32\times675=21600[/tex]
[tex]21600\div100=216[/tex]
[tex]=216[/tex]
Subtract from the original price:
[tex]675[/tex]
[tex]675-216=459[/tex]
[tex]=459[/tex]
The television after a 32% discount will cost "$459."
Hope this helps.

Step-by-step explanation:
(A). A picture of common house pets.
This wouldn't be effective since everyone knows what most common house pets look like.
(B). A picture of common pet supplies.
This wouldn't be effective since pet supplies vary with every animal.
(C). A chart displaying the amount of care pets require.

What is an equation of the line that passes through the point (-4, 5) and is perpendicular to the line 4x + y = 7?
Answers
Answer:
x -4y = -24
Step-by-step explanation:
Given the equation of a line in standard form, you can write the equation of the perpendicular line by swapping the coefficients and negating one of them. The constant needs to be adjusted to make the equation true at the point you want the line to pass through.
4x +y = 7 . . . . given line
x -4y = constant . . . . equation with coefficients swapped, one negated
x -4y = (-4) -4(5) = -24 . . . . equation with appropriate constant
An equation for the desired line is ...
x -4y = -24
__
Additional comment
The standard form equation has a positive leading coefficient, so the choice of which coefficient to negate will take that into account.
The slope of the standard form line ...
ax +by = c
is m = -a/b.
The slope of the perpendicular line is the opposite reciprocal of this:
m' = -1/m = b/a
You can see that this swaps the coefficients and negates one of them.
Find the lengths of AC. Round your answer to the nearest whole number. C a 22.69 B 13 cm A
Answers
The triangle ABC is a right triangle
The length of AC is 12.00 cm
How to determine the length of ACFrom the figure, we have the following parameters:
Length AB = 13 cm
Angle A = 22.6 degrees
Represent the length AC with b.
So, we have the following cosine ratio
[tex]\cos(A) = \frac{b}{AB}[/tex]
Substitute known values
[tex]\cos(22.6) = \frac{b}{13}[/tex]
Make b the subject
[tex]b = 13 * \cos(22.6)[/tex]
Evaluate the product
[tex]b = 12.00[/tex]
Hence, the length of AC is 12.00 cm

Cos s=-2/5 and sin t=4/5, s and t are in quadrant 4 find cos(s+t) and cos(s-t)
Answers
With Cos s=-2/5 and sin t=4/5, s and t are in quadrant 4, cos(s+t) and cos(s-t) is mathematically given as
cos(s+t)= 0.493
cos(s-t)= 0.97321
What are the values of cos(s+t) and cos(s-t)?Question Parameter(s):
Cos s=-2/5 and sin t=4/5, s and t are in quadrant 4
Generally, the equation for the s and t as functions of the 4 qudrants is mathematically given as
cos(s+t) = cos(s)*cos(t) - sin(s)*sin(t)
Therefore
cos(s+t)= -4/5 * [tex](-\sqrt{21}[/tex]/5) - (-3/5)*(-2/5)
cos(s+t)= 4*[tex]\sqrt{21}/[/tex]25 - 6/25
cos(s+t)= 0.493
In conclusion,
cos(s-t) = cos(s)*cos(t) + sin(s)*sin(t)
cos(s-t)= -4/5 * (-[tex]\sqrt{21}/[/tex]5) + (-3/5)*(-2/5)
cos(s-t)= 4[tex]*\sqrt{21}[/tex]/25 + 6/25
cos(s-t)= 0.97321
