Are points A, C, D, and F coplanar? Explain.
tatiyna
Answer: Choice B) 

The points A, C and D form a triangle which is the front face you see in the pyramid. Point F is not on this triangle at all. Point F is towards the back at the base of the pyramid away from this front face. So we consider A,C,D,F collectively as a whole to be not coplanar. If we ignored the point F, then we can say that A,C,D are coplanar.

A train stops at Atlanta, then at Bayville, and then at Colleyville. The
Nezavi [6.7K]

Answer:

See Explanation

Step-by-step explanation:

<em>The question is incomplete as what is required of the question is not stated.</em>

<em>However, since the question is only limited to distance, a likely question could be to calculate the distance from Bayville to Colleyville.</em>

Represent the distance from Atlanta to Colleyville with AC

Represent the distance from Atlanta to Bayville with AB

Represent the distance from Bayville to Colleyville with BC

So, we have that:

AC = 25.5\ miles

AB = 10\frac{2}{3}\ miles

The relationship between AB, AC and BC is:

AC = AB + BC

Make BC the subject of formula:

BC = AC - AB

BC = 25.5 - 10\frac{2}{3}

Convert fraction to decimal

BC = 25.5 - 10.7

BC = 14.8

<em>Hence, the distance from Bayville to Colleyville is 14.8 miles</em>

A family has a monthly budget of $2,400. How much money is spent on each category? 44% is spent on housing. 23% is spent on food
Lunna [17]

Answer:

  • housing, $1056
  • food, $552
  • transportation, $408
  • savings, $240
  • clothing, $144

Step-by-step explanation:

Multiply the budget total by the percentage for each category:

  • housing: 44% × $2400 = $1056
  • food: 23% × $2400 = $552
  • clothing: 6% × $2400 = $144
  • transportation: 17% × $2400 = $408
  • savings: 10% × $2400 = $240

__

Find "the rest" by subtracting the total of percentages from 100%, or by subtracting the total of budget categories from $2400. Here, everything (not including savings) adds to 90% × $2400 = $2160, so the amount to savings is 10%, or $240.

Factor by grouping 4ax-10bx+6ay-15by
Digiron [165]
Check if there is a giggle throughout the full equation, since there isn’t, we group the equation and we get

(4ax-10bx)+(6ay-15by)

Factor out the gcf of the two groups
2x(2a-5b)+3y(2a-5b)

Not sure how to explain this step in words but so do this

(2x+3y)(2a-5b)

The solution is (2x+3y)(2a-5b)
