Problem 9
By definition,
tan 22^{o} =  \frac{203}{x} \\ 0.404 =  \frac{203}{x}  \\ x =  \frac{203}{0.404}= 502.44

Answer: 502.4 m

Problem 10
From geometry, the angle opposite x is 27°.
By definition,
sin 27^{o} =  \frac{x}{580} \\ 0.454 =  \frac{x}{580} \\ x=(580)(0.454)=263.32


Answer: 263.3 yd

Which one is bigger and how do you know? 1/8 or 1/9 (Give at least two strategies) i​
scoray [572]

Answer:

1/8 is the bigger fraction

Step-by-step explanation:

When comparing fractions with different denominators, and the numerator is one, like 1/8. The one with the smaller number for the denominator is greater.

You could also compare them by finding common denominators, so for 1/8 and 1/9, a common denominator would be /63. So you would take \frac{1}{8} and multiply that by \frac{9}{9}. You would then get \frac{9}{63}. When you take \frac{1}{9} times \frac{8}{8} you get \frac{8}{63}. So when comparing you can see that 1/8 is greater than 1/9.

I need help on this with this problem
IgorLugansk [536]

Answer:

<h2>P = 40.56 ft</h2>

Step-by-step explanation:

We have three sides of a rectangle, and a semicircle.

Three sides of a rectangle: 10ft + 8ft + 10ft = 28ft.

The circumference of a whole circle: C = π(8) = 8π ft.

The semicircle: 8π : 2 = 4π ft

Using π ≈ 3.14 → 4π ≈ (4)(3.14) = 12.56 ft

The perimeter of the figure: P = 28ft + 12.56ft = 40.56ft

Juan vende 180 empanadas al día. Por la mañana vende las dos terceras partes y por la tarde la cuarta parte de lo que queda. ¿Cu
mrs_skeptik [129]

Answer:

A Juan le quedan 45 empanadas.

Step-by-step explanation:

Dado que Juan vende 180 empanadas al día, y por la mañana vende las dos terceras partes y por la tarde la cuarta parte de lo que queda, para determinar cuántas empanadas le queda por vender en la noche se debe realizar el siguiente cálculo:

180 x 2 / 3 = 120

180 - 120 = 60

60 x 1/4 = 15

60 - 15 = 45

Por lo tanto, a Juan le quedan 45 empanadas.
