Answer:

39.95 + 1.99x Option D.

Step-by-step explanation:

Sara bought shoes costs = $39.95

and x pairs of socks costs = $1.99 each

To calculate the total money that Sara spent we will multiply x by $1.99 and add it to the cost of shoes that is $39.95.

the expression will be

39.95 + 1.99x

Option D will be the answer.

Solve x2-8x=3 by completing the square. which is the solution set of the equation
Mazyrski [523]

we have

x^{2}-8x=3

Complete the square. Remember to balance the equation by adding the same constants to each side

x^{2}-8x+16=3+16

x^{2}-8x+16=19

Rewrite as perfect squares

(x-4)^{2}=19

(x-4)^{2}=19\\ (x-4)=(+/-)\sqrt{19} \\ \\ x1=4+\sqrt{19} =8.359\\ x2=4-\sqrt{19} =-0.359

therefore

the answer is

x1=4+\sqrt{19} =8.359\\x2=4-\sqrt{19} =-0.359

The safety instructions for a 20 foot ladder say the ladder should not be inclined more than 70 degrees with the ground. suppose
Romashka [77]

Answer: the distance of the base of the house to the foot of the ladder is 6.84 feet

Step-by-step explanation:

The scenario is shown in the attached photo.

Right angle triangle ABC is formed when the ladder leans against the wall of the house.

AC = the height of the ladder

AB = x feet = distance of the base of the house to the foot of the ladder

BC is the wall of the building.

To determine x, we will apply trigonometric ratio

Cos # = adjacent/hypotenuse

Where

# = 70 degrees

Hypotenuse = 20

Adjacent = x

Cos 70 = x/20

x = 20cos70

x = 20 × 0.3420

x = 6.84 feets

Geometry Question: BK bisects angle ABC and M angle ABK=28.3 degrees. Find M angle KBC and M angle ABC.
Nookie1986 [14]

Answer:

ABK = 28.3

Step-by-step explanation:

Given

ABK = 28.3

Required

Determine KBC

Since BK is a bisector of ABC at B,

this implies that:

ABK = KBC

Substitute 28.3 for ABK

28.3 = ABK

Reorder

ABK = 28.3
