You have 4/5 of a square and you need to divide it by 1 & 1/4. How many pieces would you have?

Mathematics

lukranit [14]3 years ago
5 0

Answer:

The number of pieces would be 16/5

Step-by-step explanation:

Here, we have 4/5 of a square and we want to divide it by a quarter (1/4) so we would know the number of pieces we will have.

This is pretty straightforward.

What needs to be done here is to directly divide the parts of the square we have by 1/4

Mathematically, that would be ;

4/5 ÷ 1/4

by straight arithmetic, that would be 4/5 * 4/1 = 16/5

what are the explicit equation and domain for an arithmetic sequence with a first term at eight in the second term of 5
olga nikolaevna [1]

Answer:

f(n) = 8 -  3f(n-1)

d : {  8 >= x }

Step-by-step explanation:

Basically we know 8 is the first term, so we subtract 3 to get 5 which is the second term. Then we know d = -3. Now we that we established the formula, let's make a domain. We know x can never be greater than 8 so x is always less than or equal to 8.

What is the measure of NET?<br><br> 50°<br> 65°<br> 90°<br> 130°
Illusion [34]

Answer:

The measure of the angle NET is 65 degrees (choice #2)

Step-by-step explanation:

Because ET is tangent,  <NTE is 90 degrees. Since we are given <TNG=25 degrees, we can use the fact that the sum of the angles in the triangle ENT is 180 degrees to calculate the remaining <NET:

<NET = 180 - 90 - 25 = 65 degrees

Factor: 9x^2 + 15x.
slega [8]

Answer:

3(3x^2 + 5)

Step-by-step explanation:

step 1: find out the greatest common factor (GCF) of the number 9 and 15

ex: 9x^2 + 15x   (3 * 3x^2 + 3 * 5)

step 2: factor out the common term 3

ex: 3 * 3x^2 + 3 * 5   (3 * 3x^2 + 5)

step 3: simplify the equation

3 * 3x^2 + 5   [3(3x^2 + 5)]

When Θ = 5 pi over 3, what are the reference angle and the sign values for sine, cosine, and tangent?
Sonbull [250]

Answer:

the reference angle is given by \frac{\pi}{3}

sine = negative

cosine = positive

tangent = negative

Step-by-step explanation:

We have been given the angle \theta=\frac{5\pi}{3}

The angle lies in Quadrant IV. Hence, in order to find the reference angle, we can subtract this angle with  2\pi

Therefore, the reference angle is given by

2\pi - \frac{5\pi}{3} \\\\=\frac{\pi}{3}

In Quadrant IV, cosine and secant functions are positive and rest trigonometric functions are negative.

Thus, we have

sine = negative

cosine = positive

tangent = negative
