Anvisha [2.4K]

Answer:

$87.50

Step-by-step explanation:

first minus the number of minutes he doesn't have to pay

400 - 150 = 250

then times the number of leftover minutes by how much it costs a minute ($.35 because 35¢ is equal to $.35)

250 × $.35 = $87.50

that's how much.

Answer and Step-by-step explanation:

Use Pythagorean Theorem for 6 and 9.

$8^{2} + w^{2} = 14^{2} \\\\\\w^{2} = 132\\\\\\2\sqrt{33} = w = 11.49$

7. Use Cosine, and then Tangent.

$cos(30) = \frac{15}{y} \\\\y = \frac{15}{cos(30)\\\\}\\\\y = 10\sqrt{3}, or 17.32$

$tan(30) = \frac{x}{15} \\\\15tan(30) = x\\\\5\sqrt{3} = x = 8.66$

8. Use Sine.

$sin(theta) = \frac{23}{42} \\\\theta = sin^{-1} (\frac{23}{42} )\\\\theta = 33.2$

y = 7

$7^{2} +7^{2} = x^{2} \\\\98 = x^{2} \\\\7\sqrt{2} = x = 9.9$

NISA [10]

X is unknown

Quarters 25x

Dimes 10(x+5)

Nickes 5 (x-4)

Solve for x first

25x + 10(x+5) + 5(x-4) = 470

40x + 50 - 20 = 470

40x = 440

x = 11, number of quarters
