Answer:

112°

Step-by-step explanation:

1/2(248 - 112) = 68

2 equations with 2 unknowns

x = intercepted arc, y = rest of the circle

x + y = 360

1/2 (y - x) = 68

1/2 ((360 - x) - x) =68

360 - 2x = 136

224 = 2x

112 = x

Multiply the fractions: 2 / 5 ∙ 3 / 4.

Bingel [31]

Answer:

$\frac{3}{10}$

Step-by-step explanation:

$\frac{2}{5} * \frac{3}{4}$ can be solved by just multiplying the numerators together and the denominators together

2 * 3 = 6 and 5 * 4 = 20 so the answer would be $\frac{6}{20}$

This simplifies to $\frac{3}{10}$

Given the following exponential function, identify whether the change represents

Pavel [41]

Answer:

Step-by-step explanation:

This equation represents exponential decay. Whenever the base is less than 1, the function represents decay. When the base is greater than 1, the function represents growth. In this case, the base is .97 which is less than 1, representing decay.

The formula for exponential decay is y=a(1-r)x.

r is the decay rate, expressed as a decimal.

In this case, r = .03 which represents 3%!

Solve for x & y plsssss, sorry.

Answer:

$\huge\boxed{x=29;\ y=51}$

Step-by-step explanation:

This is Isosceles triangle (look at the picture).

We know:

All triangles have internal angles that add up to 180°

Therefore:

$(x-2)+(x-2)+(4x+10)=180$

combine like terms:

$(x+x+4x)+(-2-2+10)=180\\\\6x+6=180\qquad|\text{subtract 6 from both sides}\\\\6x=174\qquad|\text{divide both sides by 6}\\\\x=29$

(x - 2)° and 3y° are supplementary angle (Two Angles are Supplementary when they add up to 180°).

Therefore:

$3y+(x-2)=180$

substitute x = 29 and solve for y:

$3y+(29-2)=180\\\\3y+27=180\qquad|\text{subtract 27 from both sides}\\\\3y=153\qquad|\text{divide both sides by 3}\\\\y=51$

Area of a square tile is the same as the area of a rectangular tile that is 18 inches long and 8 inches wide

wolverine [178]

Answer:

12 in

Step-by-step explanation:

Area of rectangle:

A = lw = 18*8 = 144 in²

Area of square:

A = a²
a² = 144
a = √144
a = 12 in
