A diagonal of a cube measures

Mathematics
1 answer:
Gennadij [26K]2 years ago
4 0

Answer: 7cm

Step-by-step explanation:

Use pythagorean theorum:

Variables:

Let the edge = A

Face diagonal (F) = 10cm

Inner diagonal (I) = sqrt(150) cm

A^2 = I^2 - F^2

A^2 = [sqrt(150)]^2 - 10^2

A^2 = 150 - 100

A^2 = 50

A = sqrt(50)

A = 7.0710678 cm

A = 7cm (to the nearest tenth)

so, length of an edge = 7cm

Answer:

450

Step-by-step explanation:

Solution for What is 75 percent of 600:

75 percent * 600 =

(75:100)* 600 =

(75* 600):100 =

45000:100 = 450

Now we have: 75 percent of 600 = 450

Question: What is 75 percent of 600?

Percentage solution with steps:

Step 1: Our output value is 600.

Step 2: We represent the unknown value with $x$x​.

Step 3: From step 1 above,$600=100\%$600=100%​.

Step 4: Similarly, $x=75\%$x=75%​.

Step 5: This results in a pair of simple equations:

$600=100\%(1)$600=100%(1)​.

$x=75\%(2)$x=75%(2)​.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

600

x​=

100%

75%​​

Step 7: Again, the reciprocal of both sides gives

x

600​=

75

100​

Therefore, $75\%$75%​ of $600$600​ is $450$
