Area=1/2 times base times height
base=4
height=3
area=1/2 times 4 times 3
area=2 times 3
area=6 square units
X represent the number of laps Marcy swam, 114x represent the number of times Toni swam.
20 + 0.80(114x) + 15 + 0.85x = 257
20 + 91.2x + 15 + 0.85x = 257
92.05x + 35 = 257
Required equation is 92.05x + 35 = 257
The total percent discount on the jeans is 35% amounting to $77
<h3>Discount</h3>
- Cost of a pair of jean = $220
- Discount from last season = 15%
- Discount from Thanksgiving day = 20%
Total percentage discount = 15% + 20%
= 35%
Amount of discount = Total percentage discount × Cost of a pair of jean
= 35% × $220
= 0.35 × 220
= $77
Therefore, the total percent discount on the jeans is 35% amounting to $77

Answer:
the height of the porch is H=1.91 m
Step-by-step explanation:
neglecting friction and assuming that the porch is horizontal, then the horizontal speed is v₀= 4 m/s and it does not change , thus he hits the base at
t= L/v₀ , L= horizontal distance
then for vertical motion , since the vertical velocity vy is 0 , the initial height is H ( the height of the porche) and the final height hf is 0 , we have
hf = H + vy*t - 1/2*g*t²
0 = H + 0 -1/2*g*t²
H = 1/2*g*t² = 1/2*g*(L/v₀)²
replacing values with g= gravity = 9.8 m/s²
H = 1/2*g*(L/v₀)² = 1/2*9.8 m/s² *( 2.5 m/ 4 m/s)² = 1.91 m
therefore the height of the porch is H=1.91 m
I think you can solve it by doing this:
10(10,000+0.06)= Final Balance
6 months + 6 months = 1 year
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
She has to pay twice a year
Now that we know that just multiply 2 by 5 and you get 10. 10(10,000+0.06)= Final Balance
So it should be 100000.6
Not sure if that's right so ask someone to check
