Answer:
The mark-up percentage is 70%
Step-by-step explanation:
Let us revise the rule of the mark-up percentage
[tex]M=\frac{S-P}{P}[/tex] × 100%, where
M is the mark-up percentageS is the selling priceP is the purchasing pricelet us use this rule to solve the question
∵ The buyer purchased leather couches in bulk, paying $750 each
∴ P = 750
∵ The stores will sell each leather couch for $1,275
∴ S = 1,275
→ Substitute them in the rule above
∴ [tex]M=\frac{1275-750}{750}[/tex] × 100%
∴ [tex]M=\frac{525}{750}[/tex] × 100%
∴ M = 70%
∴ The mark-up percentage is 70%

PLEASE HELP simplify (6 1\4) ^4
Answer:
[tex](\frac{390625}{256 } )[/tex]
Step-by-step explanation:
The exponent decides how much times does the base needs to multiply itself. In the given expression, the exponent is 4. Thus, 6 1/4 needs to multiply itself 4 times.
⇒ [tex](6 \frac{1}{4}) ^4[/tex]Convert 6 1\4 into improper fraction
⇒ [tex](\frac{25}{4} ) ^4[/tex]⇒ [tex](\frac{25}{4})(\frac{25}{4})(\frac{25}{4})(\frac{25}{4})[/tex]⇒ [tex](\frac{25^{4}}{4^{4} } )[/tex]⇒ [tex](\frac{390625}{256 } )[/tex]Thus, the simplified fraction is [tex](\frac{390625}{256 } )[/tex].

Suppose that ∠BNR and ∠RNA are adjacent angles where m∠BNR=12w-19,
m∠RNA= ¼(w+199), and m∠BNA=2(12w-19).
What is the value of W
Answer:
Step-by-step explanation:
Sum of interior adjacent angle is 180 degrees.
Given
m∠BNR=12w-19,
m∠RNA= ¼(w+199)
m∠BNA=2(12w-19).
Substitute
m∠BNR+m∠RNA=
¼(w+199)+12w-19, = 2(12w-19).
W+796+48W-76 = 96W-152
49W-96W = -152+76-796
-47W = 872
W = 872/47
W = 18.55

Multiplying two neg equals a positive
any expression multiplied by 1 stays the same
use commutative property to reorder the terms
Answer:
-60
Step-by-step explanation:
Yeah, of course!.
Step one: Breaking the problem into different problems is probably the best!
Step two: 4× (-1) is simple multiplication, any number multiplied by 1 is always the number. 4 multiplied by 1 is always 4, but there is a negative sign in front of the 1, so that means we have to go into the positive an negative rules, final answer is 4 for that step.
Then were going to ignore the multiplication sign for now.
Step three: (-3) times (-5) is 15 but we have to look at the rules of positives and negatives, a negative plus a negative is a positive. So its 15.
Step four: Multiply the two answers (4 times 15) is 60. Now were going to add our negative sign because a positive plus a positive number is a negative.
Hope this helped! :)
How does a dilation affect the side lengths and angle measures of a figure?
After the dilation, the lengths are multiplied by the value of the scale factor while the angles remain same.
What is image dilation?An enlargement or reduction of a figure that preserves shape but not size.All dilations are similar to the original figure.Dilations have a center and a scale factor.Given is to find how dilation affect the side lengths and angle measures of a figure
Assume that the initial length of the figure
After the dilation, the coordinates will become -
(x, y) → (Kx, Ky)
Where {K} is the scale factor by which the image is dilated.
The angles after the dilation remain same.
Therefore, after the dilation, the lengths are multiplied by the value of the scale factor while the angles remain same.

Make a number line and mark the points that represent the following values of x. 10∙x=0
The point on a number line is the location of the point.
How to draw the number lineThe points are given as:
x = 10 and x = 0
This means that we mark a point at the point 10 on the number line, and another point at the point 0 on the same number line
However, the point 0 would come before point 10 because 0 is less than 10

Find A1 in a geometric series for which sn=3045,r=2/5, and an=120
Answer:
a = 1875
Step-by-step explanation:
Sum of geometric series formula:
[tex]S_n=\dfrac{a(1-r^n)}{1-r}[/tex]
Geometric series formula:
[tex]a_n=ar^{n-1}[/tex]
Given:
[tex]S_n=3045[/tex][tex]r=\dfrac25=0.4[/tex][tex]a_n=120[/tex][tex]\implies 120=a(0.4)^{n-1}[/tex]
[tex]\implies a=\dfrac{120}{(0.4)^{n-1}}[/tex]
[tex]\implies 3045=\dfrac{a(1-0.4^n)}{1-0.4}[/tex]
[tex]\implies 3045=\dfrac{a(1-0.4^n)}{0.6}[/tex]
[tex]\implies 1827=a(1-0.4^n)[/tex]
[tex]\implies a=\dfrac{1827}{1-0.4^n}[/tex]
Equate equations for a:
[tex]\implies \dfrac{120}{(0.4)^{n-1}}=\dfrac{1827}{1-0.4^n}[/tex]
Apply exponent rule [tex]a^{b-c}=\dfrac{a^b}{a^c}[/tex]
[tex]\implies \dfrac{120}{\frac{0.4^n}{0.4^1}}=\dfrac{1827}{1-0.4^n}[/tex]
[tex]\implies \dfrac{48}{0.4^n}=\dfrac{1827}{1-0.4^n}[/tex]
[tex]\implies 48(1-0.4^n)=1827(0.4^n)[/tex]
[tex]\implies 48-48(0.4^n)=1827(0.4^n)[/tex]
[tex]\implies 48=1875(0.4^n)[/tex]
[tex]\implies 0.4^n=\dfrac{48}{1875}[/tex]
[tex]\implies 0.4^n=0.0256[/tex]
Taking natural logs:
[tex]\implies \ln0.4^n=\ln0.0256[/tex]
[tex]\implies n\ln0.4=\ln0.0256[/tex]
[tex]\implies n=\dfrac{\ln0.0256}{\ln0.4}[/tex]
[tex]\implies n=4[/tex]
Substituting found value for n into one of the equations and solving for a:
[tex]\implies a=\dfrac{120}{(0.4)^{4-1}}[/tex]
[tex]\implies a=\dfrac{120}{0.4^3}[/tex]
[tex]\implies a=\dfrac{120}{0.064}[/tex]
[tex]\implies a=1875[/tex]
