1 1/5 divided by 3/10

Answers

Answer: 4. This is because 1 and 1/5 = 1.2 and 3/10 = 0.3 and 1.2 divided by 0.3 = 4. That's because 1.2 can be split into 4 equal groups and each group has 0.3.

A computer monitor has a width of 12 in. and a height of 9 in. What is the diagonal length of the monitor?

Answers

Answer:

15 in

Step-by-step explanation:

Using the formula d² = l² + w², we can substitute the numbers into their correct spots.

d x d = 9 x 9 + 12 x 12

d x d = 81 + 144

d x d = 225

Now we need to figure out what d is

15 x 15 = 225

So

15 squared = 9 squared + 12 squared

Meaning the answer is 15 in.

a number n decreased by 5

Answers

Answer:

n - 5

Step-by-step explanation:

Decreased = subtractionn decreased by 5 = n - 5

I hope this helps!

The new number after decreasing the original number "n"  by 5 is (n - 5).

Let the unknown number = n

When a number is decreased by another number, it implies that the new number or outcome will be the difference between the two old or original numbers.

To decrease the number by 5, you will subtract 5 from the number as shown below;

the unknown number is decreased by 5:  n - 5

Thus, the new number after decreasing the original number "n"  by 5 is (n - 5).

The length of a room is 6.25 feet longer than the width, x. Write a expression that represents the perimeter of the room

Answers

Answer:

P=4x+12.5

Step-by-step explanation:

Step one:

given data

width W= x

Length L= (x+6.25)

We know that the perimeter of a rectangle is expressed as

P=2L+2W

P=2(x+6.25)+2(x)

P=2x+12.5+2x

collect like terms

P=2x+2x+12.5

P=4x+12.5

Hence the expression for the Perimeter is

P=4x+12.5

The perimeter of a square is equal to the perimeter of an equilateral triangle. The length of a side of the square is given by x, and the length of a side of the equilateral triangle is given by x + 1. Which equation can be used to find the value of x?
x = 3 (x + 1)
3 x = 4 (x + 1)
4 x = 3 (x + 1)
x = x + 1

Answer:

4x=3(x+1)

Step-by-step explanation:

Perimeter of the square with side length x is 4x

Perimeter of the triangle with side length x+1 is

3*(x+1)

Answer:

43 degrees

Step-by-step explanation:

A line is 180

180-86= 94

Since both angles are equal to each other. Split 94

94/2 = 47

90 degrees for the other side.

one triangle is 180 total.

add it up and subtract 180 to find the missing angle.

180 - 47+90 = 43
