price of the shoes was $90. What was the
percent of
decrease
?
PLEASE HELP ASAP
Answer:
20%
Step-by-step explanation:
So, I would set this up as a proportion-
72 x
90 100
Cross multiply-
100 x 72 = 7200
Divide-
7200/90 = 80
Subtract-
100 - 80 = 20
So, it is a 20% decrease
What is an equation of the line that passes through the point (-1,-3)(−1,−3) and is perpendicular to the line x-2y=14x−2y=14?
Answer:
No Solution
Step-by-step explanation:
The equations given are:
x-2y=14
14x-2y=14
The only solution to this system is (0, -7) and therefore there is No Solution.

Prove or disprove that point (4.00, 4.50) lies on circle O centered at the origin.
Answer:
(4.0 , 4.5) to the center is not the distance of radius
Step-by-step explanation:
circle formula centered at origin: x² + y² = r²
x² + y² = 6² = 36
(4)² + (4.5)² = 16 + 20.25 = 36.25 ≠ 36

For f (x) = 3x + 1 and g(x) = x^2 -6, find (f-g) (x)
Answer:
D
Step-by-step explanation:
(f - g)(x) = f(x) - g(x), so
f(x) - g(x)
= 3x + 1 - (x² - 6) ← distribute by - 1
= 3x + 1 - x² + 6 ← collect like terms
= - x² + 3x + 7 → D

Alex is a stockbroker. Earns % commission each week. Last week, sold $ worth of stocks. How much did he make last week in commission? If he averages that same amount each week, how much did he make in commission in 2011?
Answer:
a. $896
b. $46,592
Step-by-step explanation:
a. Alex earns 14% of the amount of stock he sells in a week.
The week before he sold $6,400. This means that his earnings in commission are:
= 14% * 6,400
= $896
b. Commission for the year:
If he makes $896 per week, there are 52 weeks in a year. Per year he would make:
= 896 * 52
= $46,592

Answer:
b) $44Step-by-step explanation:
Barbara's cumulative gross earnings for the year up through her last pay date amount to 55000.
As per attached table this amount falls in 4% region ($50001 - $70000).
Her tax per current pay period is:
$1100*0.04 = $44Correct choice is b)

Which similarity statement is true?
ASRQ - ATRS
ASRQ - ARTQ
ASRQ - ARTS
ASRQ-AQRT
Answer:
It would be B (The 2nd option)
Step-by-step explanation:
The two triangles that can be considered similar are RTQ and SRQ. These two have one right angle and share angle Q, make them similar by AAA.
Both the 2nd option and the 4th option mention these triangles, but the triangles are not named correctly in the 4th option.
The similarity statement that is true is
ΔSRQ - ΔRTQ
The correct option is B.
What is congruent?In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.
The two triangles that are similar are RTQ and SRQ. According to the AAA (Angle-Angle-Angle) similarity criterion, since they share two congruent angles, ∠RTS and ∠STQ, they must be similar. Therefore, we can write:
ΔRTQ ~ ΔSRQ
This similarity statement means that triangle RTQ is similar to triangle SRQ. So, we can use the corresponding parts of similar triangles to write:
SR / RT = SQ / TQ = RQ / RQ
where SR, RT, SQ, TQ, and RQ are the corresponding side lengths of the two triangles.
Since RQ / RQ = 1, we can simplify the above equation to:
SR / RT = SQ / TQ
This means that the ratios of the corresponding side lengths of the two triangles are equal. We can use this to find the true similarity statement:
ΔSRQ ~ ΔRTQ
So, the correct similarity statement is:
ΔSRQ - ΔRTQ.

Evaluate if x = 4.
f(x) = = - 3x + 8
Given that,
f(x) = -3x + 8
To find,
The value of f(x) at x = 4.
Solution,
We have,
f(x) = -3x + 8
We need to find the value of f(x) at x = 4
Pu x = 4 in f(x).
f(4) = -3(4) + 8
= -12 +8
= -4
So, f(4) is equal to -4.
