Part A
1 day = 1/4 hours of practice
7 days = 7/4 hours of practice (multiply both sides by 7)
1 week = 7/4 hours of practice
1 week = (4+3)/4 hours of practice
1 week = (4+3)/4 hours of practice
1 week = (4/4)+(3/4) hours of practice
1 week = 1+(3/4) hours of practice
1 week = 1 & 3/4 hours of practice
side note: 1 & 3/4 = 1.75
=======================================
Part B
Take the result from part A, and multiply it with 60
So we'll have 60 times 1&3/4 on the left side on the first line, then 60*(1+3/4) on the right side of this same line.
The rest of the lines look like this
(60*1) + (60*3/4)
60 + 60*3/4
60 + 180/4
60 + 45
105 minutes
Answer:
The polynomial is 2 x² - 2x + 7
Step-by-step explanation:
Given polynomial
(8 x² + 9 ) - (6x² +2x +2)
= 8 x² +9 - 6x² - 2x -2
= 8x² - 6x² - 2x + 9-2
= 2 x² - 2x + 7
The polynomial is 2 x² - 2x + 7
The formula for cosine is adj/hyp. For angle B, 10 is the adjacent and 24 is the opposite. The hypotenuse ( in this case, 26) is the longest side. the ratio for angle b would be 10/26.
Answer:
10 more girls
Step-by-step explanation:
So here 2/3 of 24 ran for first race
Then it gives us that 16 girls ran for first race.
Next, 1/4 of 24 ran for second race
That is 6 girls
The remaining girls ran for the third race,
24 - 22
2 girls
16 - 6 = 10
So for first race 10 more girls ran
