Answer:

Step-by-step explanation:

Convert 30% to a decimal:

30% = 0.30

Check each item by multiplying the original price by 0.30 (the 30% off sale). Subtract the product from the original price. If the sale price is the same, the pricing is correct. If they are different, the pricing is incorrect.

Headphones:

24.50 × 0.30

7.35

24.50 - 7.35

17.15

17.15 = 7.35? Incorrect.

Phone Charger:

29.25 × 0.30

8.775

29.25 - 8.775

20.475

Round to the nearest cent (hundredths place):

20.48

20.48 = 20.48? Correct.

Minitablet:

117.95 × 0.30

35.385

117.95 - 35.385

82.565

Round to the nearest cent:

82.57

82.57 = 82.57? Correct.

Printer:

213.45 × 0.30

64.035

213.45 - 64.035

149.415

Round to the nearest cent:

149.416

149.416 = 207.47? Incorrect.

Flat Screen TV:

376.98 × 0.30

113.094

376.98 - 113.094

263.886

Round to the nearest cent:

263.89

263.89 = 236.89? Incorrect.

Solve for q (Please show all work thank you:))

Masja [62]

Answer:

q = ± $\frac{5}{4\sqrt{p} }$

Step-by-step explanation:

We are to solve for q in:

16pq² = 25

q² = $\frac{25}{16p}$

$\sqrt{q^2}$ = ± $\sqrt{\frac{25}{16p} }$ = ± $\frac{5}{4\sqrt{p} }$

Wheeler Company can produce a product that incurs the following costs per unit: direct materials, $10.30; direct labor, $24.30,

salantis [7]

Answer:

Incremental cost of buying = $2.50

Step-by-step explanation:

Cost per unit;

Direct materials = $10.30

Direct labor = $24.30

Overhead = $16.30

Total Overhead cost = 10.30 + 24.30 + 16.30

= $50.90

Where the item is purchased,

Total cost = $46.88 + (40% × 16.30)

= $46.88 + $6.52

= $53.40

Cost difference = $53.40 - $50.90

= $2.50

There is an incremental cost of buying. This amounts to $2.50

Find the equation of the line that is perpendicular to the line

ddd [48]

Answer:

$y=-x+16$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept (the value of y when x is 0)
Perpendicular lines always have slopes that are negative reciprocals (ex. 3 and -1/3, 5/6 and -6/5, etc.)

1) Determine the slope (m)

y=x-9

Rewrite the equation

y=1x-9

Now, we can identify clearly that the slope of the line is 1. The negative reciprocal of 1 is -1, so therefore, the slope of a perpendicular line would be -1. Plug this into $y=mx+b$ :

$y=-1x+b\\y=-x+b$
