Antonio has $350 to spend on skis. Sales tax is 6%. Decide if each description of a price and discount, plus sales tax, represents a pair of skis that Antonio can purchase with the money he has. Choose yes or no for each description.
Answer: See explanation
Step-by-step explanation:
Antonio has $350 to spend on skis. sales tax is 6%. decide if each description of a price and discount, plus sales tax, represents a pair of skis that antonio can purchase with the money he has. choose yes or no for each description. a. 25% off $450 b. 20% off $385 c. $20 off $360 d. 15% off $360 e. $10 off $340.
The amount of money that Antonio can spend will be:
= $350 - (6% × $350)
= $350 - (0.06 × $350)
= $350 - $21
= $329
a. 25% off $450
= $450 - (25% × $450)
= $450 - (0.25 × $450)
= $450 - $112.50
= $337.50
No
b. 20% off $385
= $385 - (20% × $385)
= $385 - (0.2 × $385)
= $385 - $77
= $308
Yes
c. $20 off $360
= $360 - $20
= $340
No
d. 15% off $360
= $360 - (15% × $360)
= $360 - $54
= $306
Yes
e. $10 off $340
= $340 - $10
= $330
No.
Based on the $329 that Anthony has, he can make purchases on:
b. 20% off $385
d. 15% off $360

Step-by-step explanation:
-10x + 9 = -11
-10x = -20
x = 2
Answer:
x=2
Step-by-step explanation:
−10x+9=−11
−10x+9−9=−11−9
−10x=−20
−10x /−10 = −20 /−10
x=2

Answer:
y = 3
Step-by-step explanation:
Subtract 11 from both sides to get:
2y = 6
Then divide both sides by 2 to isolate y:

A communications company has developed three new designs for a cell phone. To evaluate consumer response, a sample of n = 120 college students is selected and each student is given all three phones to use for one week. At the end of the week, the students must identify which of the three designs they prefer. The distribution of preference is as follows: Design 1=54, Design 2=38, Design 3=28. Do the results indicate any significant preferences among the three designs?
Answer:
The answer is "Its results are not consistent with its three designs Yes. Its results show significant differences between both the three designs."
Step-by-step explanation:
Following are the distribution of preference:
[tex]Design 1 =54 \\\\ Design 2=38 \\\\\ Design 3=28 \\\\[/tex]
[tex]Design \ \ \ \ \ \ \ \ \ \ O_i \\ 1 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 54 \\2 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 38\\3 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 28 \\Total \ \ \ \ \ \ \ \ \ \ 120[/tex]
An expected frequency([tex]E_i[/tex]) has 40 Null hypotheses to take n=120.to each design:
The effects of the three designs are standardized
Inaccurate.
Hypothesis Alternative:
The effects of the three prototypes are not uniform
Degrees Of freedom [tex]=(n-1)=(3-1)=2[/tex]
[tex]H_o, x^2 \ test\ statistic \ \sum_i {\frac{(O_i -E_i)^2}{E_i}} \\[/tex]
[tex]= \frac{(54 -40)^2}{40}+\frac{(38-40)^2}{40} + \frac{(28-40)^2}{40}\\\\=49+0.1+3.6\\\\=8.6[/tex]
Chi-squared distribution critical value at [tex]\alpha = 0.05 (x^2 _{0.052})=5.99[/tex]
Since [tex]x^2, a[/tex] value [tex]> x^2 -[/tex]table of [tex]\alpha =0.05 =5.99[/tex]is determined.
So[tex]H_o[/tex] is rejected.

I NEED HELP QUICKLY PLEASE. POSSIBLY GIVING BRAINLIEST.
A computer technician charges a flat rate for home visits plus $ 55 per hour. The technician bills $190 for a 2-hour home visit to install a new hard drive. The equation y − 190 = 55(x − 2) gives the total amount y the technician charges for x hours of work.
The equation in slope-intercept form is y = 55x + 80.
What does the y-intercept in this equation represent?
a. the rate of change
b. the total cost
c. the flat rate
IT IS NOT A. I TRIED AND GOT IT WRONG.
Answer:
y - 190 = 55(x - 2)....distribute thru the parenthesis
y - 190 = 55x - 110....now add 190 to both sides
y = 55x - 110 + 190..simplify
y = 55x + 80 <== slope intercept form (y = mx + b)

C. 2 x 4/5
D. 4 x 2/5
C. 2 x 6/5
Answer:
B, C, and D
Step-by-step explanation:
A) 5 x 1/8 is 5/1 times 1/8 which is 5/8 (Incorrect)
B) 8 x 1/5 is 8/1 times 1/5 (multiply straight across and you get 8/5 (Correct)
C) 2 x 4/5 (again, it's 2/1 just multiply straight across and you are basically only multiplying the two numerators each time. Because 1 times 5 will always be 5) (Correct)
D) Correct because 4 times 2 is 8 which is over 5, hence, 8/5 (Correct)
E) 2 times 6 is 12 over 5 which is 12/5, not 8/5. (Incorrect)

5.3x - 9 + 7.6x
Answer:
12.9x-9
Step-by-step explanation:
First you have to combine the like terms which are 5.3x + 7.6x= 12.9x. Then you just rewrite the equation 12.9x-9. You just leave the 9 by it self beacuse thers no other like terms.
Anwer
12.9x−9 :)
5.3x+−9+7.6x
Combine Like Terms:

Abby has to measure the weight of objects in pounds for her homework, but she only has a scale that measures ounces. If she finds an object weighs 48 ounces, how many pounds does it weigh?
Answer: 3 pounds
Step-by-step explanation: 1 pound=16 ounces
Now that you know what the conversion from ounces to pounds is, you just have to divide the number of ounces in the problem (48) by 16.
48÷16=3
Four times the sum of a number and seven is twenty three.
Answer:
[tex]\frac{-5}{4}[/tex]
Step-by-step explanation:
You're going to want to set up an algebraic equation to solve this. It would look like this: 4(x+7)=23. Using distributive property, you'd get 4x+28=23. Subtract 28 from both sides to isolate 4x, and you'd get 4x=-5. Divide by 4 on both sides to isolate x and you'd get x=[tex]\frac{-5}{4}[/tex].
CHECK:
To check, plug in x.
4([tex]\frac{-5}{4}[/tex]+7)=23.
Use distributive property and get [tex]\frac{-20}{4}[/tex]+28=23. This simplifies to -5+28=23, which is correct.

What is half of 36 kg
half of 36 kg will be 18 kg
The half of the 36 kg is obtained by dividing the quantity by 2 and it is 18 kg.
The division is a mathematical operation that contains decoupling a quantity or number into equal proportions. It is the inverse operation of multiplication. In division, a number called the dividend is divided by another number called the divisor to get the quotient. When a number is not completely divisible by another number, then dividing the number leaves a single digit that cannot be divided further by that number, thus digit is known as the remainder.
Divide 36 kg by 2,
Half of 36 = [tex]\frac{36}{2} = 18[/tex].
