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

Step-by-step explanation:
Susan's time = 5:55
Jamal's time = 11:42
Half of Jamals time = 5:51
5:55<5:51

100
. Explain what Emma did incorrectly and use the model to correct her work. Solve the problem in your answer.
The fraction that represents the addition model shown above will be 53/100.
How to solve the fraction?From the information given, a grid with 10 equal columns is shown with 5 shaded in. This will be expressed as 5/10.
Also, a second grid is shown, identical in size, containing 100 squares with 3 shaded in. This will be expressed as 3/100.
Therefore, the problem that represents the addition model shown above will be:
= 5/10 + 3/100
= 50/100 + 3/100
= 53/100
In this case, the answer given by Emma is incorrect as he added 5 to 3 and got 8/100.

B) It has a slope of 4.
C) It is parallel to the y-axis.
D) It passes through the point (0,4).
Answer:
the answer is D
Step-by-step explanation:
Because the point of x=4 is passed through the point (0,4).
What is an equation of the line that passes through the point (-4, 5) and is perpendicular to the line 4x + y = 7?
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
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
