because 4 x 3 = 12
5 x 3 = 15
what is perpendicular to 3x+4y+12=0?
Answer:
y=4/3x-3
Step-by-step explanation:
We can rearrange the equation for y-intercept form:
3x+4y+12=0
4y=-3x-12
y=-3/4x-3
The perpendicular equation would have an inverse slope, so we flip -3/4
y = 4/3x -3

2. A coupon has been issued for crackers at the local grocery store. The crackers originally retail for $3.79 a box and the coupon is good for 10% off the price marked on the shelf. When you arrive at the store the crackers are already marked down by 15%. What is the price you will pay for the box of crackers?
Answer:
$3.54
Step-by-step explanation:
$3.79-25% (because you add the 15% + 10%)
which is $3.54
Answer:
$2.90
Step-by-step explanation:
start with original price
$3.79
marked down 15%
3.79 × .15 = .5685 or .57
3.79 - .57 = 3.22 price on shelf
minus 10% coupon
3.22 × .1 = .322 or .32
$3.22 - .32 = $2.90

A store buys a TV for $100. They sell it for a 70% mark-up. What is the new cost of the TV?
Answer:
170
Step-by-step explanation:
Since the TV is worth $100 initially but has a 70% markup, it means they increased the price by the percent markup
100 x .70 = 70
100 + 70 = $170
The new cost of the TV sold at this store is equal to $170.
Given the following data:
Cost price = $100Markup = 70%To determine the new cost of the TV sold at this store:
How to calculate markup price.We would calculate the markup price by multiplying the cost price by the markup.
[tex]Markup\;price = \frac{70}{100} \times 100\\\\Markup\;price = 0.7\times 100[/tex]
Markup price = $70
Now, we can find the new cost of the TV:
[tex]New\;cost = Markup\;price + Cost\;price\\\\Total\;cost = 70 + 100[/tex]
Total cost = $170.

"Find the total area of the shape"
How should I solve this? The answer is 31.9 cm²
Answer:
31.9 cm² (3 s.f.)
Step-by-step explanation:
[tex]\boxed{area \: of \: sector = \frac{θ}{360º} \times \pi {r}^{2} }[/tex]
∠AOD
= 360° -60° - 120° -45° (∠s at a pt.)
= 135°
Area of shape
[tex] = \frac{60°}{360°} (\pi)({2}^{2}) + \frac{120°}{360°} (\pi)(3^{2} )+ \frac{45°}{360°}(\pi)( 5 {}^{2}) + \frac{135°}{360°} (\pi)(3 {}^{2} )[/tex]
[tex] = \frac{1}{6} (4\pi) + \frac{1}{3} (9\pi) + \frac{1}{8} (25\pi) + \frac{3}{8} (9\pi)[/tex]
[tex] = \frac{4}{6} \pi + \frac{9}{3} \pi + \frac{25}{8} \pi + \frac{27}{8} \pi[/tex]
[tex] = \frac{61}{6} \pi[/tex]
