Answer:
-3/2
Step-by-step explanation:
Using the slope formula, we can find the slope of the line shown
m = ( y2-y1)/(x2-x1)
= ( -1-3)/(-3-3)
= -4/-6
= 2/3
A line that is perpendicular is the negative reciprocal
-1/ (2/3) = -3/2
Answer:
The circumference is also 7 times larger
12 cm radius :2*pi*12= 75.43
12*7=84
84cm radius: 2*pi*84= 528
To check if its indeed 7 times larger: 528/75.43 and you'll get 7
If youre looking for the difference between the two: 528-75.43= 452.57
Answer:
Let total number of boys be b.
ratio of boys after 14 boys leave is
(b - 14) / p = 3 / 10
=> 3 p = 10 b - 140
=> 10 b = 3 p + 140
= > b = 0.3 p + 14
Answer:
-20
Step-by-step explanation:
(r + b − g)(b + g)
we have fom statement:
r = 9
b = 5
g= −6
so we have:
(r + b − g)(b + g)= (9+5-(-6))*(5+(-6))
(r + b − g)(b + g)= (14+6)*(-1)
(r + b − g)(b + g)= -20
Answer:
i). 211.
ii). 711.
iii). 31
iv). 131.
Step-by-step explanation:
i). √37460 = 193.545
Then take the whole number from the decimal:
193² = 193 × 193 = 37249
You subtract the answer from the main number:
37460 - 37249 = 211
211 is the answer.
ii). √506900 = 711.969
711² = 711 × 711 = 505521
506900 - 505521 = 1379
1379 is the answer.
iii). √4931 = 70.221
70² = 70 × 70 = 4900
4931 - 4900 = 31
31 is the answer.
iv). √5607 = 74.879
74² = 74 × 74 = 5476
5607 - 5476 = 131
131 is the answer.
