Answer:

TOTAL TAX IS: $19.25

TOTAL PRICE IS: $294.25

MONEY LEFT IS: $135.75

Step-by-step explanation:

First, you do a proportion:

?/275 = 7/100

the ?/275 represents how much money in $275

the 7/100 represents 7% (7 hundredths)

then you cross multiply:

275 x 7 = 1925

then you divide:

1925 divided by 100 = 19.25

<em><u>So $19.25 is the tax amount.</u></em>

<em><u></u></em>

To get the total price, you add:

Tax ($19.25) + Cost($275) = $294.25

<u><em>$294.25 is the total amount that Anna has to pay.</em></u>

<u><em></em></u>

To get what Anna has left over, you subtract:

Has($430) - Spend($294.25) = $135.75

<u><em>Anna has $135.75 left.</em></u>

<u><em></em></u>

I hope this helped you a lot!

What is the equation of the line that passes through the point (-4, 2) and has a slope of 1/4?​
natulia [17]

Answer:

y = 1/4x + 3

Step-by-step explanation:

m = 1/4, (-4,2)

y -2 = 1/4(x - - 4)

y - 2 = 1/4 (x + 4)

y - 2 = 1/4x + 1

y = 1/4x + 1 + 2

y = 1/4x + 3

Answer:

  • Maria–Ava: 15.7 feet
  • Lucas–Maria: 10.1 feet
  • angle at Maria: 50°

Step-by-step explanation:

The cosine and tangent functions are useful here. The relevant relations are ...

  Cos = Adjacent/Hypotenuse

  Tan = Opposite/Adjacent

__

The distance from Maria to Ava (ma) is the hypotenuse of the triangle, so we have ...

  cos(40°) = 12/ma

  ma = 12/cos(40°) ≈ 12/0.76604 ≈ 15.7 . . . feet

__

The distance from Lucas to Maria (ml) is the side opposite the given angle, so we have ...

  tan(40°) = ml/12

  ml = 12·tan(40°) ≈ 12·0.83910 ≈ 10.1 . . . feet

__

The angle formed at Maria's position is the complement of the other acute angle in the right triangle:

  M = 90° -40° = 50°

In summary, ...

  • Maria–Ava: 15.7 feet
  • Lucas–Maria: 10.1 feet
  • angle at Maria: 50°

abruzzese [7]

Complete Question

Because triangle XYZ is a right triangle, the side lengths must satisfy the Pythagorean theorem, a² + b² = c², which in this isosceles triangle becomes a² + a² = c². By combining like terms, 2a² = c². Which final step will prove that the length of the hypotenuse, c, is StartRoot 2 EndRoot times the length of each leg?

a) substitute values for a and c into the original pythagorean theorem equation.

b) divide both sides of the equation by two, then determine the principal square root of both sides of the equation.

c) determine the principal square root of both sides of the equation.

d) divide both sides of the equation by 2.

Answer:

c) determine the principal square root of both sides of the equation.

Step-by-step explanation:

Pythagoras Theorem for a right angled triangles states that:

a²+ b²= c²

But for an Isosceles Triangle, where two sides of the triangle are equal, we have:

a²+ a² = c²

By combining like terms

2a² = c²

We square root both sides of the equation.

√2a² = √c

√2a² = c

The final step will prove that the length of the hypotenuse, c, is StartRoot 2 EndRoot times the length of each leg = √2a² = c is Option c.
