Answer:

C. 2

Step-by-step explanation:

Slope = (y2-y1) / (x2-x1) , (x1,y1) = (1,-5) , (x2,y2)=(4,1)

= (1-(-5)) / (4-1)

= (1+5) / 3

= 6/3

= 2

Given a right ?ABC, where AB = 4.5 cm, BC = 7.794 cm, and AC = 9 cm, sketch the triangle below, and find the measure m?C in degr
Ksju [112]

Answer:

The measure of angle C is 30\°

The draw in the attached figure

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC

The sine of angle C is equal to divide the opposite side to angle C by the hypotenuse

sin(C)=\frac{AB}{AC}

substitute the values

sin(C)=\frac{4.5}{9}

C=arcsin(\frac{4.5}{9})=30\°

The price of a pair of pants is $29.95 and the sales tax is 5%.
Vika [28.1K]

Answer: $31.45

Step-by-step explanation:

Given : The price of a pair of pants is $29.95.

The sales tax is 5% = 0.05

Required formula :

Total cost = Price + sales tax percent × Price

Total cost= Price (1+Sales tax percent)

i.e. Total cost of the pair of pants= 29.95 (1+0.05) =29.95(1.05)=31.4475 ≈ 31.45

Hence, the total cost of the pair of pants = $31.45

How do I solve -5 - (15y - 1) = 2 (7y - 16) - y
Aleks [24]
If you want to solve the equation -5 - (15 * y - 1) = 2 * (7 * y - 16) - y, you can calculate this using the following steps:

-5 - (15 * y - 1) = 2 * (7 * y - 16) - y
-5 - 15 * y + 1 = 14 * y - 32 - y
-5 + 1 + 32 = 14 * y - y + 15 * y
28 = 28 * y    /28
y = 1

The result is 1.

Find the distance between the two points rounding to the nearest tenth (if needed)
Ede4ka [16]

Answer:

6.3 units (nearest tenth)

Step-by-step explanation:

\boxed{Distance \: between \: 2 \: points =  \sqrt{ {(x1 - x2)}^{2} +  {(y1 - y2)}^{2}  } }

Using the formula above,

distance between (-8, 6) and (-6, 0)

=  \sqrt{ {[ - 8 - ( - 6)]}^{2}  +  {(6 - 0)}^{2} }

=  \sqrt{ {( - 8 + 6)}^{2}  +  {(6 - 0)}^{2} }

=  \sqrt{ {( - 2)}^{2} + 6^{2}  }

=  \sqrt{4 + 36}

=  \sqrt{40}

= 6.3 units (nearest tenth)
