Irst thought: since he needs 7 3/4 tons, and each load can carry LESS than a ton, he'll need to make MORE than 7 3/4 loads. So when you get your answer, make sure it it passes that common sense test. Next: He's got to divide the 7 3/4 ton total among all those loads, 3/4 ton at a time. So he needs to divide: 7 3/4 divided by 3/4. It will be easier to do the math if we turn 7 3/4 into an improper fraction, which will be 31/4. So we have to divide 31/4 divided by 3/4, which will give us 10, with 1/4 left over, for a total of 10 1/4 loads. BUT: the wording is that each load carries AT MOST 3/4 ton, so he may carry less than that amount in any given load(s). So he needs to do an amount GREATER THAN OR EQUAL TO 10 3/4 loads. For practical purposes, that means he has to fill his truck (at least part way) 11 different times. (Think of it as completely filled the first 10 times, and 3/4 filled on the 11th/final time.)

A camper wants to know the width of a river. From point A, he walks downstream 60 feet to point B and sights a canoe across the

Anarel [89]

<h2>Hello!</h2>

The answer is:

The correct option is:

D. 40 feet.

To solve the problem and calculate the width of the river, we need to assume that the distance from A to B and the angle formed between that distance and the distance from A to the other point (C) is equal to 90°, meaning that we are working with a right triangle, also, we need to use the given angle which is equal to 34°. So, to solve the problem we can use the following trigonometric relation:

$Tan\alpha =\frac{Opposite}{Adjacent}$

Where,

alpha is the given angle, 34°

Adjacent is the distance from A to B, which is equal to 60 feet.

Opposite is the distance from A to C which is also equal to the width of the river.

So, substituting and calculating we have:

$Tan(34\°) =\frac{Width}{60ft}$

$Width=60ft*Tan(34\°)=60ft*0.67=40.2ft=40ft$

Hence, we have that the correct option is:

D. 40 feet.

Have a nice day!

A jar pinto beans and black beans in a ratio of 1:1, and 300 of the beans are pinto beans. How many beans are there in the jar?

Serhud [2]

Answer: 600 beans

Step-by-step explanation:

Since the beans are in a ratio 1:1, you can write it like this: x/x. Since we know x=300, we can do this: x/x=300/?. We know x is again 300(given) so, x/x=300/300. Total is adding the 2 beans up which is 300+300=600

Suppose a box is to be constructed from a square piece of material of side length x by cutting out a 2-inch square from each cor

alexgriva [62]

Consider the attached figure. The central square is the "floor" of the box, and it is a (x-2)-by-(x-2) square.

The four rectangles of the side will be the "walls" of the box, and they are (x-2)-by-2 rectangles.

The volume is given by the base area multiplied by the height of the walls, so we have

$\underbrace{(x-2)(x-2)}_{\text{base area}}\times 2 = 2(x^2-4x+4)= 2x^2-8x+8$
