Write and equation and solve the problem.

The width of a rectangular window frame is 12 inches less than its length. If you add 30 inches to both the length and width, you double the perimeter. Find the length and width of the original rectangle.

Complete the conversation by choosing the correct word in parentheses.

- Brenda, ¿cuål prefieres de estas joyas, este collar de oro o 1. (aquel/aquél) collar de plata?

- Bueno, 2. (aquel/aquél) de oro es muy bonito. Además, cuesta menos que el otro.

- Sí, tienes razón. Como es tu cumpleaños, te lo regalo. Es 3. (por/para) ti.

- ¡No me digas! Muchas gracias 4. (por/para) el collar, Manuela. Eres muy bondadosa.

Complete the paragraph with the correct preterite or imperfect form of the verb in parentheses.

El lunes pasado la abuela y yo 5. (ir) a caminar por la playa y a bañarnos en el mar. 6.(Hacer) buen tiempo y 7. (estar) soleado. De repente 8. (venir) una tormenta.

Thank you!

1. To the nearest degree, find the measure of the smallest angle of a triangle with side lengths of 3, 4 and 5.

2. A right triangle has a 30 degree angle and a hypotonuse length of 6. What is its area?

What is the length of each side of a regular polygon to the nearest foot if:

apothem = 80 ft.

number of sides = 20

area = 20,000 square feet

Thanks!

Suppose you throw a baseball into the air from a starting height . You toss the ball with an upward velocity of ft/s. You can use the equation h=(-16)t^2+vt+s to find the ball's height in feet seconds after it is thrown.

A.) Suppose you toss a baseball directly upward with a starting velocity of 46ft/s from a starting height of 6ft. When will the ball hit the ground?

Info: The weight of a load is limited by the diameter of the fiber cable. As the load gets heavier, the diameter of the cable must increase. Tho raise a load weighing W tons, a fiber cable having diameter D in inches must satisfy the inequality (πd)^2 - (√15w)^2 ≥ 0

#1.) Show by factoring that this inequality is true:

(πd-√15w)(πd+√15w)≥0

#2.) Show that d ≥ √15w/π

#3.) Is a cable 3 inches in diameter sufficient to lift an object weighing 5 tons? Justify your response.

Problem: Find three different values to complete each expression so that it can be factored into the product of two binomials. Show each factorization.

x^2 - 3x - ?

x^2 + x - ?

x^2 + ?x + 12

I need a basic but complete description of the nervous system of a crayfish. Thank you!

Ok, so the question is "Is each equation a direct variation? If it is, what is the constant of variation?"

And the equations are:

y = 5/3 x

y(to the 2nd power) = 2x

3y = 8x

This is Ivy's cousin using her account. I need a good answer for this question as it it helping me study for midterms. "list 4 chain molecules that form building blocks for life"

I only heard it once and now I can't find it!

How can you not?

I have had insomnia for about 2 years and it is nearly impossible for me to sleep. I have to get up to work at 6 a.m., but don't get to sleep till -at best- 5:30. Does anyone know a way for me to get more sleep?
