Answer:
-1.25x + 0.2
Step-by-step explanation:
(-0.5x - 0.4) - (0.75x - 0.6) = -0.5x - 0.4 - 0.75x + 0.6
= -0.5x - 0.75x - 0.4 + 0.6
= -1.25x + 0.2
If the square below has an area of 50, what is the value of x
Answer:
10
Step-by-step explanation:
A= L²
50 = L² (do opposite operation to find L)
L = 7.07
x²= L²+ L²
x²= 7.07² + 7.07²
x² = 100 ( do opposite operation to make x the subject)
x = 10
Note: opposite operation of square is square root

[tex]\frac{1}{3}[/tex]x-1
Step-by-step explanation:
([tex]\frac{5}{6}[/tex]x-7)-([tex]\frac{1}{2}[/tex]x-6) =
The - sign before 6 is turned into a + sign when the bracket is removed because the arithmetic operation before the bracket is - and two - makes the second - turn into a + (It's a rule I can't rlly explain it well but yea)
[tex]\frac{5}{6}[/tex]x-7-[tex]\frac{1}{2}[/tex]x+6 = [tex]\frac{5}{6}[/tex]x-1-[tex]\frac{1}{2}[/tex]x
-7+6 makes it a -1.
[tex]\frac{5}{6}[/tex]x-[tex]\frac{1}{2}[/tex]x-1 = [tex]\frac{5}{6}[/tex]x-[tex]\frac{3}{6}[/tex]x-1
To make the denominator of the two fractions the same, I multiplied the second fraction by 3 so that both denominators are 6.
[tex]\frac{5}{6}[/tex]x-[tex]\frac{3}{6}[/tex]x-1 = [tex]\frac{2}{6}[/tex]x-1
After making the denominator the same, I can directly do the equation for the numerators (5-3=2) and keep the denominator the same.
[tex]\frac{2}{6}[/tex]x-1 = [tex]\frac{1}{3}[/tex]x-1
Since 2/6 has a common factor which is 2, I can divide both the numerators and denominators so that the fraction can be simplified further into 1/3, its simplest form.

Which brand should the store eliminate?
O A. Brand B
O B. Brand D
O C. Brand C
O D. Brand A
Answer: They should eliminate Brand C
Step-by-step explanation:
You need to divide the total returns by the total sold to which Brand has the greatest percentage returned.
The brand that the store should eliminate out of the 4 given brands using the data in the table is; Brand C
How to Solve Percentage Problems?To find the brand that the store should eliminate we need to find the percentage of sold items that were returned and pick the highest percentage as the brand the store should eliminate.
Brand A percentage = [tex]\frac{33}{685}[/tex] × 100 = 4.81%
Brand B percentage = [tex]\frac{15}{492}[/tex] × 100= 3.04%
Brand C percentage = [tex]\frac{29}{361}[/tex] × 100 = 8.03 %
Brand D percentage = [tex]\frac{31}{766}[/tex] × 100 = 4.04%
Brand C has the highest percentage and as such it is the brand that should be eliminated.

. Jada is collecting stickers. After getting 15 more stickers, she has 60 stickers in total. Select all the equations Jada can solve to find x, the number of stickers she started with.
Answer:
[tex]x + 15 = 60[/tex]
[tex]x = 60 - 15[/tex]
Step-by-step explanation:
Given
[tex]Additional = 15[/tex]
[tex]Total = 60[/tex]
Required
What equation can be used to select the initial number of stickers
Represent the initial number of stickers with x
The equation can then be written as:
[tex]x + Additional = Total[/tex]
This gives:
[tex]x + 15 = 60[/tex] ---- This is one equation
Make x the subject
[tex]x = 60 - 15[/tex] --- This is another equation
Solving further for x
[tex]x = 45[/tex]
This implies that she started with 45 stickers

Loren Weber wants to buy the sedan listed below. There is a 6% sales tax on the purchase price of the car. If Loren pays the full sticker price for the car? What is the total price?
Answer:$32,085
Step-by-step explanation:
$25,335+1,995+995+895+895+695+295+195+35+750= $32,085
Total price of the sedan that Loren Weber wants to buy = $34010.1
What Is a Sales Tax?A sales tax is a consumption tax imposed by the government on the sale of goods and services. A conventional sales tax is levied at the point of sale, collected by the retailer, and passed on to the government.
Given,
CODE DESCRIPTION MSRP
SAL 4 4 Dr. Sedan AWD $25335
85N Navigation System $1995
66E Entertainment System $995
Chrome Wheel Covers $895
Interior Convenience Package $895
SS9 Safety & Security Package $695
RSS2 Reverse Sensing System $295
SR5 Satellite Radio $195
195 EBH9 Engine Block Heater $35
E43 Destination Charge $750
Full sticker Price = 25335+1995+995+895+895+695+295+195+35+750
Full sticker Price = $32085
6% sales tax = 0.06 × $32085 = $1925.1
Total price of the car = Full price + sales tax
Total price of the car = $32085 + $1925.1
Total price of the car = $34010.1
Hence, $34010.1 is the total price of the sedan that Loren Weber wants to buy.

If you have a demand function of Qd=48-9P and a supply function of Qs=-12+6P,
what would the equilibrium QUANTITY be?
Answer:
The equilibrium quantity is 26.4
Step-by-step explanation:
Given
[tex]Q_d = 48 - 9P[/tex]
[tex]Q_s = 12 + 6P[/tex]
Required
Determine the equilibrium quantity
First, we need to determine the equilibrium by equating Qd to Qs
i.e.
[tex]Q_d = Q_s[/tex]
This gives:
[tex]48 -9P = 12 + 6P[/tex]
Collect Like Terms
[tex]-9P - 6P = 12 - 48[/tex]
[tex]-15P = -36[/tex]
Solve for P
[tex]P = \frac{-36}{-15}[/tex]
[tex]P =2.4[/tex]
This is the equilibrium price.
Substitute 2.4 for P in any of the quantity functions to give the equilibrium quantity:
[tex]Q_d = 48 - 9P[/tex]
[tex]Q_d = 48 - 9 * 2.4[/tex]
[tex]Q_d = 26.4[/tex]
Hence, the equilibrium quantity is 26.4
Given the measures a = 10, b = 40, and A = 30°, how many triangles can possibly be formed?
Answer:
no triangle can be formed with the given values (i.e 0 triangle).
Step-by-step explanation:
Given;
length of side a, = 10
length of side b, = 40
angle A, = 30°
Apply sine rule to determine the angle of the second side (B);
[tex]\frac{sin \ A}{a} = \frac{sin \ B}{b} \\\\\frac{sin \ 30^0}{10} = \frac{sin \ B}{40}\\\\sin \ B = 40(\frac{0.5}{10} )\\\\sin \ B = 2[/tex]
The maximum sine function is 1, there is no sine function that will be equal to 2, so there is no triangle that can be formed with the given values.

You buy a pair of jeans for 25% markdown from $32.00. The sales tax is 6%. How much will you pay for the jeans?
Answer:
$25.44
Step-by-step explanation:
Although the starting price of the pair of jeans is $ 32, it is 25% off. Thus, 75% of its initial value (100-25) is being paid, with which the pre-tax price is determined as follows:
32 x 0.75 = X
24 = X
In turn, at that discounted price, 6% must be calculated as sales tax, with which the final price is determined through the following calculation:
24 x 1.06 = X
25.44 = X
Therefore, the price to pay for the pair of jeans is $ 25.44.
Answer:
$25.44

When commercial aircraft are inspected, wing cracks are reported as nonexistent, detectable, or critical. The history of a particular fleet indicates that 70% of the planes inspected have no wing cracks, 25% have detectable wing cracks, and 5% have critical wing cracks. Five planes are randomly selected. Find the probability that at least one plane has critical cracks.
Answer:
0.226
Step-by-step explanation:
Given that:
No wing crack (x) = 70%
Detectable wing crack (y) = 25%
Critical wing crack (z) = 5%
Number of samples (n) = 5
Probability that atleast a plane has critical crack:
1 - p(no critical crack)
Using the multinomial distribution calculator :
P(5,0,0) + p(4,1,0) + p(3,2, 0) + p(2,3,0) + p(1,4,0) + p(0,5,0)
From the calculator :
P(5,0,0) + p(4,1,0) + p(3,2, 0) + p(2,3,0) + p(1,4,0) + p(0,5,0) = 0.7741
1 - 0.7741 = 0.2259
