Answer:
See below.
Step-by-step explanation:
1) 7/4 + 5/8
= 14/8 + 5/8
= 19/8 or 2 3/8
2) 3/2 + 4/3
= 9/6 + 8/6
= 15/6
= 5/2 or 2 1/2
3) 2/3 + 10/7
= 14/21 + 30/21
= 44/21 or 2 2/21
4) 4 - 3/17
= 68/17 - 3/17
= 65/17 or 3 14/17
Answer:
5.848 in
Step-by-step explanation:
Divide the piece of cardboard into nine equal squares of side z.
The centre square is the base of the cube.
When you cut out the corner squares and fold up the sides, you will have a cube with edge length z.
The cube must have a volume of 200 in³.
V = z³
200 = z³
![z = \sqrt[3]{200}](https://tex.z-dn.net/?f=z%20%3D%20%5Csqrt%5B3%5D%7B200%7D)
![z = \sqrt[3]{8\times25}](https://tex.z-dn.net/?f=z%20%3D%20%5Csqrt%5B3%5D%7B8%5Ctimes25%7D)
![z = 2\sqrt[3]{25}](https://tex.z-dn.net/?f=z%20%3D%202%5Csqrt%5B3%5D%7B25%7D)
z = 2 × 2.924
z = 5.848 in
The edge length of the cube is 5.848 in.
Answer:
Step-by-step explanation:
xy = 32
x ; y is the divisor of 32
but : 32 = 2^5
6 ordered pairs of positive integers satisfy xY=32
(1;32) , (2;16) , (4; 8),(32; 1) , (16;2) , (8;4) .
<span>As restaurant owner
The probability of hiring Jun is 0.7 => p(J)
The probability of hiring Deron is 0.4 => p(D)
The probability of hiring at least one of you is 0.9 => p(J or D)
We have a probability equation:
p(J or D) = p(J) + p(D) - p(J and D) => 0.9 = 0.7 + 0.4 - p(J and D)
p(J and D) = 1.1 - 0.9 = 0.2
So the probability that both Jun and Deron get hired is 0.2.</span>
