Answer:

1). The average speed is 17 mps (m per second). I know this because if you divide 34 m by 2, (in order to get the m per second) you will get 17 mps. Thats how i got my answer.

2). It would take 2.5 hours to travel 130km. I know this by dividing 139 by 52. I chose to do this because if you travel 52km/h, then dividing 130km by 52 will give you an answer

Given:

The figure of triangle ABC.

To find:

The measure of angle A.

Solution:

From the given figure, we get

[tex]\angle ABC+120^\circ=180^\circ[/tex]                 (Linear pair)

[tex]\angle ABC=180^\circ-120^\circ[/tex]

[tex]\angle ABC=60^\circ[/tex]

According to the exterior angle theorem, the exterior angle of a triangle is equal to the sum of two opposite interior angles.

[tex]\angle A+\angle ABC=105^\circ[/tex]          (Exterior angle theorem)

[tex]\angle A+60^\circ=105^\circ[/tex]

[tex]\angle A=105^\circ-60^\circ[/tex]

[tex]\angle A=45^\circ[/tex]

Therefore, the measure of angle A is 45 degrees.

Answer:

the sales tax rate is 8.59%

Step-by-step explanation:

The computation of the sales tax rate is as follows:

= Tax value ÷ Total taxes

= $10.80 ÷ ($150.52 - $24.72)

= $10.80 ÷ $125.80

= 8.59%

Hence, the sales tax rate is 8.59%

We simply applied the above formula to determine the sales tax rate

9514 1404 393

Answer

  a) correct

  b) (30, 100) would mean an area of 100 square feet is enclosed when the width is 30 feet. (Kristina's vertex coordinates are incorrect.)

Step-by-step explanation:

a) The derivation and expression for A(w) are correct

__

b) Kristina made a mistake in using her graphing calculator to find the vertex. The actual vertex is (27.5, 756.25). The coordinates of the vertex are (w, A(w)). The vertex (w, A(w)) means that the area of the enclosed space is A(w) when the width of the enclosure is w.

If Kristina's vertex coordinates were correct (which they are not), they would tell you the enclosed area is 100 square feet when the width of the enclosure is 30 feet.

Answer:

3 and 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

15y = 45x + 60 ( divide all 3 terms by 15 )

y = 3x + 4 ← in slope- intercept form

with slope m = 3

Given

6y = 12x + 36 ( divide all 3 terms by 6 )

y = 2x + 6 ← in slope- intercept form

with slope m = 2

Answer: $-5

Step-by-step explanation:

From the question, we are informed that Spencer has a bank account with a balance of $75.

We are further told that Spencer owes $30 to her credit card and she owes $50 for a LCD tv.

The amount on Sencers bank balance if both debits were paid would be:

= $75 - ($30 + $50)

= $75 - $80

= $-5

Answer:

Step-by-step explanation:

Both will be equal ,

4x-7 =3x +2

solve it we will get ,

x =9 degree

Answer:

answer is x=9

vertical angles have same angle measure.

so:

(4x-7)=(3x+2)

x=9

lets see if it correct. put x values in

4×9-7=3×9+2

Answer:

[tex]x^o+2x^o=180^o [Sum~of~angles~of~straight~line~is~180^o]\\or, 3x^o=180^o\\or, x = 60^o[/tex]

Step-by-step explanation:

x + 70° = 130° {exterior angle of a triangle is equal to the sum of two opposite interior angles}

x = 130° - 70°

x = 60°

Now for 2x = 2 * 60° = 120°
