The sum of two numbers is 7/8. One addend is 3/4. what is the other? A. 4/4 B. 1/8 C. 1/4 D. 2/8
Dmitrij [34]

Answer:


Step-by-step explanation:

Let the other be = x


As the sum of the number is given as \frac {7}{8}

And one number is \frac{3}{4}


According to question


\frac{3}{4} +x = \frac{7}{8}


Subtracting \frac{3}{4} from both sides we get


\frac{3}{4} +x - \frac{3}{4} = \frac{7}{8} - \frac{3}{4}


Taking LCM of 4 and 8 we get 8

And making

\frac{3}{4} and \frac{7}{8} like fraction by making denominator same.


Multiply \frac{3}{4} by 2 in numerator and denominator and multiply \frac {7}{8} by 1 in numerator and denominator we get


x= \frac{7}{8} - \frac{6}{8}


x= \frac{7-6}{8}


x =\frac{1}{8}


Hence, the other number is \frac{1}{8}

Raj's company ships T-shirts in boxes shaped like cubes. The picture below shows the cube
Rzqust [24]

Answer: The surface area of each cube is 24 ft² (24 square feet)

Step-by-step explanation: The boxes according to the question are shaped like cubes, which means the shape we have here has square faces on all sides. Also the boxes have been opened up into nets and this shows each box as having 6 faces.

The area of each face is derived as follows;

Area = L x W

Area = 2 x 2

Area = 4 ft²

Having calculated the surface area of each face, a box or cube with 6 faces will have its surface area as;

Area of box = Face area x 6

Area of box = 4 x 6

Area of box = 24 ft²

Therefore in designing labels for all of the boxes, Raj would need 24 square feet of label for each box.
