Answer:
12 people
Step-by-step explanation:
On the morning of the 3rd day, there are 4 working days (of the 6 days) left for 12-person crew, or 4*12 = 48 man.days
The team completed the remaining job in 2 days. This means 48 / 2 = 24 people helped complete the task.
So the number of new workers who joined the crew is
24 - 12 = 12 people
First we find the slope of the original equation
4x - 2y = 3
-2y = -4x + 3
y = -4/-2x - 3/2
y = 2x - 3/2......slope here is 2
for a parallel line, we use the same slope
y = mx + b
slope(m) = 2
(2,1)...x = 2 and y = 1
now we sub and find b, the y int
1 = 2(2) + b
1 = 4 + b
1 - 4 = b
-3 = b
so ur parallel equation is : y = 2x - 3
for a perpendicular slope, we need the negative reciprocal. All that means is flip the slope and change the sign. So we have a slope of 2...the negative reciprocal we need is -1/2
y = mx + b
slope(m) = -1/2
(2,1)...x = 2 and y = 1
now we sub again
1 = -1/2(2) + b
1 = -1 + b
1 + 1 = b
2 = b
ur perpendicular line is : y = -1/2x + 2
=========================
x + 4 = 0
x = -4....this is a vertical line with an undefined slope....sorry but I am not sure about this one
Answer:
1.8
Step-by-step explanation:
So, we can say that the square root of 3.24 is 1.8 with an error smaller than 0.001 (in fact the error is 0.0000276241). this means that the first 4 decimal places are correct. Just to compare, the returned value by using the javascript function 'Math. sqrt(3.24)' is 1.8
Well this triangles angles have to add up to 180
If E is a perpendicular bisector with V so V= 90 degrees
and E=45 degrees
90+45=135 degrees
180 degrees -135 degrees =A) S = 45 degrees.
B) I conclude VES is a isoceles triangle because it has two corresponding angles.
C) This is a complicated one lets work this out in the comment section...
D) Same as C
Answer:
Tess is correct
Step-by-step explanation:
First off, to find out the new discounted price without the sales tax, you multiply $24.50 by 15% (0.15). This gives you $3.68. You then subtract the $3.68 from $24.50. You get $20.82. To find the total with sales tax you then multiply the $20.82 by 10% (0.1). You add the discounted price with the sales tax and get the conclusion that they have enough money for the book.
