Answer:

210

Step-by-step explanation:

For getting this answer we need to find the minimum common multiplier, this is, the smaller number that is multiple of all 5, 6 and 7.

For example, 30 is multiple of both 5 and 6, son in 30 days two suppliers will come, but not the third, as 30 is not a multiple of 7.

Let's try with the next multiple of 5 and 6, this is 60, but is not a multiple of 7.

The next is 90, but again not multiple of 7. Niether are the next: 120, 150, 180.

But when we arrive to 210 we see that, as we are going from multiples of 5 and 6, and 210/7=30, 210 is also multiple of 7.

So, the answer is 210.

Find the value of x in the triangle... Then classify the triangle as acute, right or obtuse
ddd [48]

Answer:

x = 44

right

Step-by-step explanation:

The sum of the angles in a triangle add to 180

90+ 46+x = 180

Combine like terms

136+x = 180

Subtract 136 from each side

136+x-136=180-136

x =44

Since we have a 90 degree angle it is a right triangle

There are 4,200 adults in Lakeview. Three-eighths of the adults in Lakeview do not have children. How many adults in Lakeview ha
Inessa [10]

To answer this, you first have to find 3/8 of 4200 by multiplying those two numbers.

\frac{4200}{1} *\frac{3}{8}


First, multiply the numerators.

4200x3=12600

Next, multiply the denominators.

1x8=8

You end up with \frac{12600}{8}.

This fraction can be simplified to 1575.

All that's left is to subtract that number from 4200.

4200-1575=2625


The final answer is 2625 adults in Lakeview have children.
