I’m just hoping that you meant to say 10.5x instead of 10 5x

you would do 10.5x = 7.5x + 30

subtract 7.5x from both sides to get 3x = 30
finish by dividing both sides by 3

your answer should be 10 T-Shirts which would cost $105 (because you sub x for 10)

Answer:

Angle of elevation = 21.167°

Step-by-step explanation:

Given:

Horizontal distance cover by rover = 180 m

Vertical distance cover by rover = 65 m

Find:

Angle of elevation

Computation:

Using trigonometry function;

Sin θ = Perpendicular / Hypotenuse

⇒ Sin θ = Vertical distance cover by rover / Horizontal distance cover by rover

⇒ Sin θ = 65 / 180

⇒ Sin θ = 0.3611

⇒ Sin⁻¹ (0.3611) = 21.167°

Angle of elevation = 21.167°

The car is moving with a speed v0 = 48 mi/hr up the 4-percent grade, and the driver applies the brakes at point A, causing all w

lutik1710 [3]

Answer:

s = 0.2203 miles

Step-by-step explanation:

Given:

- The initial speed vo = 48 mi/hr

- The mass of the car m

- The coefficient of kinetic friction uk = 0.61

- The slope of the road 4-percent grade

Find:

Determine the stopping distance sAB. Repeat your calculations for the case when the car is moving downhill from B to A.

Solution:

- Apply the energy principle with work done against friction:

K.E_1 + P.E_1 = Wf + P_E_2 + K.E_2

- The final velocity of car is zero, K.E_2 = 0

The initial potential energy is set as zero, P.E_1 = 0

K.E_1 = Wf + P_E_2

0.5*m*vo^2 = Ff*s + m*g*h

Where, Ff is the frictional force:

Ff = uk*N

Where, N is the normal contact force between car and road. By equilibrium equation we have:

m*g*cos(θ) - N = 0

N = m*g*cos(θ)

Hence,

Ff = uk*m*g*cos(θ)

- The vertical distance travelled h is:

h = s*sin(θ)

- The energy equation is:

0.5*m*vo^2 = uk*m*g*cos(θ)*s + m*g*s*sin(θ)

0.5*vo^2 = uk*g*cos(θ)*s + g*s*sin(θ)

s*(uk*g*cos(θ) + g*sin(θ) ) = 0.5*vo^2

s = [0.5*vo^2 / (uk*g*cos(θ) + g*sin(θ) ) ]

- The slope = 4 / 100,

s = [0.5*48^2 / (0.61*8052.97*cos(2.29) + 8052.97*sin(2.29) ) ]

s = 0.2203 miles

Amelia makes necklaces using beads and wire. She starts with 6 feet of wire. How many necklaces can she make?

navik [9.2K]

If Amelia starts with 6 feet of wire, the amount of necklaces that she can make is 18.

<h3>What is the necklaces about?</h3>

Jewelry wire is known to be a kind of a wire that can be either a copper, brass, or others that are often used in jewelry making.

Note that Wire is seen today as a single unit, and it is also seen to be cylindrical, elongated part of drawn metal.

Using the table:

6 ÷ 1/3

= 6 x 3

= 18

Therefore, If Amelia starts with 6 feet of wire, the amount of necklaces that she can make is 18.

Therefore, option A is correct.
