Mathematics
1 answer:
9966 [12]4 years ago
4 0

Answer:

\angle B=23.96\\\\\angle C=59.04

Step-by-step explanation:

\:The\:law\:of\:sines\:is:\\\\\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}

with\\\\A=97\\\\a=22\\\\b=9\\\\c=19

so\:we\:have\\\\\frac{\sin 97}{22}=\frac{\sin B}{9}\\\\\sin B=\frac{9\sin 97}{22}\\\\B=\sin^{-1}(\frac{9\sin 97}{22})\\\\B\approx 23.96

You\:could\:use\:the\:law\:of\:sines\:again\\\\But\:remember\:that\:the\:sum\:of\:angles\:is\:180\\\\\angle A+\angle B+\angle C=180\\\\97+23.96+\angle C=180\\\\120.96+\angle C=180\\\\\angle C=59.04

Everyday, Kevin has to drive 7 miles each way to work and back. At work, he has to drive his truck on a 296-mile delivery route.
Vedmedyk [2.9K]

Answer:

1550 miles

Step-by-step explanation:

Every day, he has to drive his car 7 miles to work and 7 miles back, making a total of 14 miles. Adding this to the 296 mile delivery route, that is a total of 310 miles a day. Multiplying this by the 5 days in his workweek, you get a total of 1550 miles. Hope this helps!

8xy= 2(2x + y) solve for y
STatiana [176]

Answer:  \displaystyle y= \frac{2\text{x}}{4\text{x} - 1}

============================================

Work Shown:

8\text{x}y= 2(2\text{x} + y)\\\\8\text{x}y= 4\text{x} + 2y\\\\8\text{x}y - 2y= 4\text{x}\\\\y(8\text{x} - 2)= 4\text{x}\\\\y= \frac{4\text{x}}{8\text{x} - 2}\\\\y= \frac{2*2\text{x}}{2(4\text{x} - 1)}\\\\y= \frac{2\text{x}}{4\text{x} - 1}\\\\

---------------

Explanation:

The idea is to first get all the y terms to one side. I did this by subtracting 2y from both sides in the third step.

Then factor out y and divide both sides by (8x-2)

Afterward there's the optional steps of simplifying (as shown in the final two steps).

Iteru [2.4K]
Let's get the data out of the problem:

d = 38.4 km

t = 6 h

Now, we can apply in this equation and find his speed:

v = d / t

v = 38.4 / 6

v = 6.4 km/h

Joe has a speed of 6.4 km/h.

Hope it helps.
