Answer:
$11.25$1.31Step-by-step explanation:
Initial price = $30Mark down = 37.5%Sales tax = 7%The markdown amount is:
$30*37.5/100 = $11.25The markdown price is:
$30 - $11.25 = $18.75The sales tax amount is:
$18.75*7/100 = $1.31 (rounded to the nearest cent)Answer:
Marked down amount = $11.25
Sales tax amount = $1.31
Explanation:
The initial amount Andrew bought the book was $30.
If the book was later marked down by 37.5%, therefore the marked down will be;
[tex] \frac{37.5}{100} \times 30 = 0.375 \times 30 = 11.25[/tex]
The marked down price will be;
[tex]30 - 11.25 = 18.75[/tex]
If the sales tax rate was 7%, the sales tax amount will be;
[tex] \frac{7}{100} \times 18.75 = 1.31[/tex]

Which proportion can be used to find the arc length, s, in units?
Answer:
Option B
Step-by-step explanation:
Formula to be used to calculate the length of an arc,
Length of arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]
Here, θ = Angle subtended at the center by the arc
r = radius of the circle
By substituting values in the formula,
s = [tex]\frac{150}{360}(2\pi )(42)[/tex]
[tex]\frac{s}{2\times 42\pi }=\frac{150}{360}(\frac{2\times 24\pi }{2\times 24\pi } )[/tex]
[tex]\frac{s}{84 \pi }=\frac{150}{360}[/tex]
Therefore, Option B will be the answer.

what is 5 times a number minus 3 is 12 ?
Answer:
5*x-3=12
the number is 3 because 5*3=15 and 15-3=12
Answer:
3
Step-by-step explanation:
x - 3 = 12
12 + 3 = 15
15 - 3 = 12
5( ? ) = 15
15/5
? = 3
5(3) = 15 - 3 = 12

Rewrite this expression without using absolute value
I nEeD hElP qUiCk!
Answer:
Step-by-step explanation:
Normally when you are doing an absolute value question, you do it like this
y = abs(4x - 12) and you write the absolute value equation as
y = 4x - 12 and
y = - 4x + 12
These two are shown in graph27a
to show both wings of the absolute value curve
This is slightly different.
I think you would write this as
y = 4x - 12 {r <3} where the restriction is outside the equation written with curly brackets. You should see both graphs together. The discussion of r<3 is shown in graph 27b

In the figure below, ∠HFG≈HKJ and ∠HF≈HK
Using the information provided, select the triangle congruence criterion that can BEST be used to prove that
ΔHFG≈ΔHKJ.
A. angle-angle-side (AAS)
B. angle-side-angle (ASA)
C. side-side-angle (SSA)
D. side-angle-side (SAS)
Answer:
D
Step-by-step explanation:
The triangles ΔHFG and ΔHKJ are congruent with each other by ASA postulates. Then the correct option is B.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
The ratio of the matching sides will remain constant if two triangles are comparable to one another.
In triangles ΔHFG and ΔHKJ, then the condition is given as,
∠HFG = ∠HKJ (Given)
HF = HK (Given)
∠FHG = ∠JHK (Vertically opposite angles)
The triangles ΔHFG and ΔHKJ are congruent with each other by ASA postulates. Then the correct option is B.

write down the multiples of 7 between 44 and 54.
The multiples of 7 between 44 and 54 is, 42 and 49
What are multiples ?In mathematics, when we multiply one whole number by another whole number, we have multiples as the result. Or, to put it simply, when you multiply a number, you receive its multiples
Given that,
A number 7,
We have to found multiples of 7 between 44 and 54
Let's identify the multiples of 7 that are not zero to see how that aids in our understanding of multiples.
The multiples of Seven that are not zero are,
7x1 = 7,
7x2 = 14,
7x3 = 21,
7x4 = 28,
7x5 = 35,
7x6 = 42,
7x7 = 49,
7x8 = 56
We can see that the lists of the multiples of Seven.
Hence, the multiples are in between 44 and 54 are, 42 & 49

Answer:
the answer is y=30x
Step-by-step explanation:
however many inches times 30 is the consistent answer to the equation
Answer:
y=30x
Step-by-step explanation:
We can start out by writing our slope-intercept form equation: y=mx+b. In this case, our y-intercept is 0, so we can write y=mx.
Let's find the slope. We can take the points (1,30) and (2,60). We can use the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] to find our slope. Plug these values in, and we get [tex]\frac{60-30}{2-1}[/tex]. Evaluate this, and our slope is 30. So, our equation is y=30x.

8x = 160
x = 160/8
x = 20
