Answer:
21 windows
Step-by-step explanation:
colleen's family plans to paint the windows of their house. her father will paint twice as many windows as her mother, and Colleen and her 2 brothers will paint an equal number of the rest of the windows. Colleen decided to do her own share and her mother's share and paints 7 window, which is one less than her father's share. how many windows are in their house?
Answer: Let the number of window Colleen father would paint be x while that of her mother be y. Since her father will paint twice as many window as her mother, therefore the number of windows painted by the father x = 2y
Let the number of windows each painted by Colleen and her 2 brothers be z since they would paint the same number of windows. The total number of windows to be painted = 2y + y + z + z + z = 3y + 3z = 3(y + z).
Then number of windows needed to be painted by Colleen and her mother is given as z + y. Since Colleen painted 7 windows as her share and her mother share i.e. y + z = 7
Therefore the total number of windows = 3(y + z) = 3(7) = 21 windows
Is that a triangle prism? Sorry I'm bad at shapes but I can do the area if I know what shape it is
Yes the supervisor’s calculation is correct because you add the numbers and get 11,000
Answer:
<u>As we proved, the common ratio of the sequence is 1/4.</u>
Step-by-step explanation:
Let's find the common ratio of the sequence, this way:
A. What number modifies 2/3 into 1/6?
1/6 ÷ 2/3 =
1/6 * 3/2 = (flipping the reciprocal when we change from division to multiplication)
3/12 = 1/4
B. What number modifies 1/6 into 1/24?
1/24 ÷ 1/6 =
1/24 * 6/1 = (flipping the reciprocal when we change from division to multiplication)
6/24 = 1/4
C. What number modifies 1/24 into 1/96?
1/96 ÷ 1/24 =
1/96 * 24/1 = (flipping the reciprocal when we change from division to multiplication)
24/96 = 1/4
<u>As we proved, the common ratio of the sequence is 1/</u>4.
