help please work has to be shown ..

Answers

Answer:

x = 7 and y = 17

Step-by-step explanation:

16x + 9x + 5 = 180 cuz they are supplementary

25x = 175

x = 7

We also know that 16x + 4y = 180

so 16(7) + 4y = 180, so 4y = 180 - 112, so 4y = 68. y = 17

hope this makes sense

Bidet used a computer algebra system (CAS) to find the quotient of (4x^3+2x^2+3x+5)^2 and x^2+3x+1. Which statement correctly shows a way to enter this problem into a CAS?

A. Division[4x^3+2x^2+3x+5^2, x^2+3x+1]
B. Division[ (4x^3+2x^2+3x+5)^2] [x^2+3x+1]
C. Division[ (4x^3+2x^2+3x+5)^2, x^2+3x+1]
D. Division[2 (4x^3+2x^2+3x+5), x^2+3x+1]

Answers

Answer: Choice C. Division[ (4x^3+2x^2+3x+5)^2, x^2+3x+1]

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

Explanation:

It honestly depends on the CAS program, but for GeoGebra for instance, the general format would be Division[P, Q]

Where,

P = numerator = (4x^3+2x^2+3x+5)^2Q = denominator = x^2+3x+1

As another example, let's say we want to divide x^2+5x+6 all over x^3+7 as one big fraction

We would type in Division[x^2+5x+6, x^3+7]

if you have a triangle with a=90 , angle b=50 , find angle c

Answers

Answer: m<C = 40

Step-by-step explanation:

Triangle angle sum theorem states that the interior angles of a triangle sum to 180. We have two angles 90 and 50. Now we need to find the third. 90+ 50 +<C = 180. 140+ C = 180. C = 40

Answer:

40

Step-by-step explanation:

sum of angle in a triangle is 180

180=90+50+c

180=140+c

180-140=c

40=c

c=40°

Carly mowed 2 more lawns than Rocco each week for 6 weeks. Carley mowed a total of 18 lawns. How many lawns did Rocco mow each week?

Answers

Rocco mowed 1 lawn a week.

You wanna divide Carley’s total mowed lawns by the amount of weeks she mowed for.
18/6 = 3
Carley mowed 3 lawns a week.
We’ll take away two from that because she mowed two more that Rocco each week, resulting in Rocco mowing one lawn a week.

What is m∠1?................

Answers

Answer:

144

Step-by-step explanation:

to find the missing angle in side of the triangle we subtract 111 and 33 from 180

180-111-33=36

so the angle inside of the triangle equals 36 to find the one on the outside of the triangle we subtract 36 from 180

180-36 which equals 144 so 1=144

Pablo is on a road trip which will cover a distance of 840 miles. He plans to break the trip up and will complete it over three days. The distances and average speeds for the first two days are shown below.Day One: 55 hours at an average speed of 66 miles per hour. Day Two: 55 hours at an average speed of 58 miles per hour. If the average speed on the third day is 55 miles per hour, how many more hours will it take for Pablo to complete his trip?

Answers

Answer: 2.87 hours

Step-by-step explanation:

There may be a typo in the question because 55 hours in a day is not logical so you must have meant 5.5 hours.

In that case, the hours he will require on the third day would require the distance left to calculate. Get this distance from the first 2 days.

Day 1 distance travelled = Time * Speed

= 5.5 * 66

= 363 miles

Day 2 distance travelled = Time * Speed

= 5.5 * 58

= 319 miles

Total distance remaining

:= 840 - 363 - 319

= 158 miles

Travelling at 55 miles per hour, the time to be taken is:

= Distance remaining / Speed

= 158 / 55

= 2.87 miles per hour
