C: (4, -12)

you are driving to a friends house at 35 miles per hour and the friend lives 21 miles away. how long to get to the house

Answers

Answer:

35miles/1 hr=21miles/x hr

= x hr* 35miles/1 hr= 21 miles

= x = 21/35 =0.6 hr

So, traveling at 35mph it will take 0.6 hours to travel 21 miles.

If you want time in mins then keep going:

=> 60 mins = 1 hour, 0.6 hours = x mins

60mins/1 hr = x mins/ 0.6 hr

0.6 * 60 mins = 36 mins.

:. It takes 0.6 hrs or 36 mins to drive 21 miles at a constant speed of 35mph

Name the asymptote for the graphed function.

y = 2
y = 4

Answers

y=2

There is one horizontal asymptote present

See the line of graphed function is approaching to 2 but not crossing y=2 .Instead it is trying to be parallel with x axis.Hence the horizontal asymptote is at y=2

Answer:

angle 4 = 56°

Step-by-step explanation:

Interior angles in the same side of the transversal are supplementary (their sum is 180°)

Angle 1 and 4 are interior angles on the same side of the transversal.

So, angle 1 + angle 4 = 180°

Angle 1 = 124° (given)

124 + angle 4 = 180°

angle 4 = 180° - 124° = 56°

Therefore, angle 4 = 56°

A triangle has sides with lengths of 17 inches, 20 inches, and 28 inches. Is it a right triangle?

Answers

Answer:

no

Step-by-step explanation:

Pythagoras theorem

a2 + b2 = c2

the hypotenuse side is always the longest so its 28

:

[tex]17 { }^{2} + 20 ^{2} = 28 ^{2} [/tex]

289+ 400 =784

689 = 784

so the triangle is not a right angled triangle

Find a, R, and T.

Answers

a = 4, R = 147, T = 33

Step-by-step explanation:

find a

a/(a + 7) = (16/3)/(44/3)

a/(a + 7) = 16/44

44a = 16a + 112

44a - 16a = 112

28a = 112

a = 112/28

a = 4

find R

2x + 5 = 3x - 9

5 + 9 = 3x - 2x

14 = x

m ∠R = 180° - (2x + 5)

= 180 - (2(14) + 5)

= 180 - (28 + 5)

= 180 - 33

= 147°

find T

m ∠T = 3x - 9

= 3(14) - 9

= 42 - 9

= 33°

So if we rotate them to be equivalent

Add 4 to both sides
4y = 32
Divide by 4
Y =8

Minus 65 from both sides
10x = 70

Please help. I can't figure it out.

Answers

Answer:

see explanation

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides )

Here n = 5 , then

sum = 180° × 3 = 540°

Sum the given angles and equate to 540

2b - 90 + 90 + b + 45 + b + [tex]\frac{3}{2}[/tex] b = 540, collect like terms

4b + 1.5b  + 45 = 540 ( subtract 45 from both sides )

5.5b = 495 ( divide both sides by 5.5 )

b = 90

then

2b - 90 = 2(90) - 90 = 180 - 90 = 90

b + 45 = 90 + 45 = 135

[tex]\frac{3}{2}[/tex] b = 1.5b = 1.5 × 90 = 135

The angles from least to greatest are

90° , 90° , 90° , 135° and 135°

50 = -1/3b + 20

what is b?

Answers

To find b, start by subtracting 20 from both sides:

50 = -1/3b + 20

-20 -20

30 = -1/3b

Now isolate b by dividing both sides by -1/3:

30/(-1/3) = (-1/3b)/(-1/3)

-90 = b

b is 90!
