A certain bag of potting soil is 1/4 peat moss, and the rest is dirt. What part is dirt?
Troyanec [42]

Answer:

D = 1 - \frac{1}{4}

D = \frac{3}{4}

Step-by-step explanation:

Given:

1 bag of potting soil

Peat Moss = \frac{1}{4}

Required

What part is dirt?

The whole bag of potting soil is represented as 1;

Let P represent Peat Moss and D represented Dirt; Such that

P + D = 1

Subtract P from both sides

P - P + D = 1 - P

D = 1 - P

Substitute \frac{1}{4} for P

D = 1 - \frac{1}{4}

Take LCM

D = \frac{4-1}{4}

D = \frac{3}{4}

<em>Hence, </em>1 - \frac{1}{4}<em> or </em>\frac{3}{4}<em> of the potting soil is Dirt</em>

Consider this sequence: -81, -54, -36, -24, … . The sequence is . The common ratio of the sequence is . The sum of the first fiv
solong [7]

Answer:

The reason for the decreasing sequence is \frac{2}{3}

the sum of the sequence is -243

Step-by-step explanation:

Note that the numbers are decreasing so we will use the following formula to find the sum:

S∞=\frac{t1}{1-q},

where t1 is equal to the first number of the sequence and q is the reason that gives the following results.

to find q this form is used;  

q= \frac{t2}{t1}= \frac{-54}{-81} =\frac{2}{3}

then we replace in the formula of the sum to find the total

Which of the following are properties of the circumcenter of a triangle? Check
Alex_Xolod [135]

Answer: A. The circumcenter is at the intersection of the perpendicular bisectors of the triangle's sides.

C. The circumcenter is equidistant fromeach vertex of the triangle.

D. The circumcenter is equidistant from each side of the triangle.

Step-by-step explanation:

The properties of the circumcenter of a triangle from the options given include:

• The circumcenter is at the intersection of the perpendicular bisectors of the triangle's sides.

• The circumcenter is equidistant fromeach vertex of the triangle.

• The circumcenter is equidistant from each side of the triangle.

Option B is wrong as the circumcenter of an obtuse triangle is not always outside it. For the circumcenter, there is intersection of all the three lines and it's not important that they should always be outside.
