Patricia but 16 hair clips for three dollars X number of hair clips cost $.15 each of the rest cost $.20 each write inequality i
Sholpan [36]

Answer:

The inequality in therms of x is 0.15x+0.2(16-x)\leq 3.

Patricia had bought at least <u>4 hair clips</u> of cost $0.15 each.

Step-by-step explanation:

Given:

16 hair clips = $3

x hair clips = $0.15 each

(16-x) hair clips = $0.20 each

We need to find the minimum number of hair clips of $0.15 that she bought.

Solution:

Now we can say that;

x hair clips multiplied by $0.15 plus (16-x) hair clips multiplied by $0.2 should be less than or equal to 3.

framing in equation form we get;

0.15x+0.2(16-x)\leq 3

Hence The inequality in therms of x is 0.15x+0.2(16-x)\leq 3.

0.15x+3.2-0.2x\leq 3

Combining like terms we get;

0.15x-0.2x\leq 3-3.2\\\\-0.05x\leq -0.2

Dividing both side by -0.05 we get;

\frac{-0.05x}{-0.05}\leq \frac{-0.2}{-0.05}\\\\x\geq 4

Hence Patricia had bought at least <u>4 hair clips</u> of cost $0.15 each.

KIM [24]
The answer is D.
the base of the pyramid is lxh which is .75 x .75 = 0.5625
Each of the sides are triangles which are 1/2 bxh which equals .6/2 = .3
there is 4 triangular sides so .3 x 4 = 1.2
and 1.2 + 0.5625 = 1.7625.

Solve the triangle.
Reika [66]

Answer:

cute scalene triangle.

Sides: a = 1   b = 2   c = 1.906

Area: T = 0.94

Perimeter: p = 4.906

Semiperimeter: s = 2.453

Angle ∠ A = α = 29.543° = 29°32'36″ = 0.516 rad

Angle ∠ B = β = 80.457° = 80°27'24″ = 1.404 rad

Angle ∠ C = γ = 70° = 1.222 rad

Height: ha = 1.879

Height: hb = 0.94

Height: hc = 0.986

Median: ma = 1.888

Median: mb = 1.147

Median: mc = 1.262

Inradius: r = 0.383

Circumradius: R = 1.014

Vertex coordinates: A[1.906; 0] B[0; 0] C[0.166; 0.986]

Centroid: CG[0.691; 0.329]

Coordinates of the circumscribed circle: U[0.953; 0.347]

Coordinates of the inscribed circle: I[0.453; 0.383]

Exterior (or external, outer) angles of the triangle:

∠ A' = α' = 150.457° = 150°27'24″ = 0.516 rad

∠ B' = β' = 99.543° = 99°32'36″ = 1.404 rad

∠ C' = γ' = 110° = 1.222 rad
