Answer:
$44,998.85
Step-by-step explanation:
Price of the car = $42,055
Tax = 7%
Total cost = Price of the car + amount of tax
= 42,055 + 7% of 42,055
= 42,055 + 7/100 * 42,055
= 42,055 + 0.07 * 42,055
= 42,055 + 2,943.85
= 44,998.85
Total cost = $44,998.85
Answer:
-x + 20y
Step-by-step explanation:
trust me.. its right
Y=mx+b b is the y intercept which is 4
m is the slope which is rise over run which is -4/2 which is -2
Linear y=-2x+4
Step-by-step explanation:
Sin<D = Opposite / Hypotenuse
Opposite - EC
Hyp - DE
Sin<D = EC/DE = x/9
we need x to find <D.
so -->Use pythagorean theorem.
DE^2 = EC^2 + DC^2
DE = 9 DC = 7 EC = ?
EC^2 = DE^2 - DC^2 rearranged.
= 9^2 - 7^2
= 81 - 49
EC^2 = 32 Put both sides under square root.
√(EC^2) = √32
EC = 4√2 ~ 5.65.
We now have X which was representing the unknown side EC.
Sin<D = EC/DE = 5.65/9 = 0.627
To find <D Take the sine inverse of of 0.627.
<D = Arcsin(0.627) = 38.82°.
We now know <D. It's <E's turn.
A right angle triangle has a summation of interior angles of 180°.
thus, <em><D + <C + <E = 180°</em>
38.82° + 90° + <E = 180°
128.82° + <E = 180°
subtract both sides by 128.82°
0 + <E = 180° - 128.82°
<em><E = 51.</em><em>2</em><em>°</em>
