Leslie and her family went out to dinner last night. The total bill was $78.44 after the 6% tax. How much was the bill before ta

sleet_krkn [62]

Answer:

$74

Step-by-step explanation:

you convert the percent to a decimal, .06, and try multiplying it with the numbers before 78, so you multiply it with 77, 76, 75, then 74, and when you multiply it with 74 you get 78.44.

Or you figure out the total amount money wise that the tax would count as and subtract that from 78.44.

{d(1)=13<br> {d(n)=d(n−1)+17 <br> Find the 4 term in the sequence

pickupchik [31]

d(4) = 64

Step-by-step explanation:

Step 1:

d(n)=d(n−1)+17 

d(2) = d(1) +17

= 13+17

= 30

d(3) = d(2) + 17

= 30+17

=47

Step 2:

d(4) = d(3) + 17

= 47+17

= 64

Solve the triangle.<br> A = 32°, a = 19, b = 14

Paha777 [63]

Answer:

A = 32°, a = 19, b = 14, B=22.98°, C = 125.02°, c = 29.36

Step-by-step explanation:

We have two sides of the triangle and we have an angle.

A = 32 °, a = 19, b = 14

We use the sine theorem to find the angle B.

We know that according to the sine theorem it is true that:

$\frac{sin(A)}{a}=\frac{sin(B)}{b}=\frac{sin(C)}{c}$

$\frac{sin(32\°)}{19}=\frac{sin(B)}{14}$

$sin(B)=14*\frac{sin(32\°)}{19}\\\\B=Arcsin(14*\frac{sin(32\°)}{19})\\\\B=22.98\°$

We know that the sum of the internal angles of a triangle is always equal to 180.

So:

$C=180-32-22.98\\\\C=125.02\°$

Finally we find the c side

$\frac{sin(A)}{a}=\frac{sin(C)}{c}$

$\frac{sin(32\°)}{19}=\frac{sin(125.02)}{c}$

$0.02789=\frac{sin(125.02)}{c}$

$c=\frac{sin(125.02)}{0.02789}\\\\c=29.36$
