Step-by-step explanation:
1 ton = 2,000 Pounds
110 x 5 = 550
You multiply by 5 because 2,000 x 5 = 10,000.

Hope that helped.
Eh, here's my best try for a table:
<u>Like tv</u> <u> don't like tv</u> <u>total</u>
<u>Like reading:</u> 70 10 80
<u>Don't like read</u>. <u>20</u> <u>30</u> <u>50 </u>
<u>total </u> 90 40 130
The percentage of students that like tv as well as reading is- 70 divided by 130 which gives you .538 which in percentage is 53.8%.
The probability of a student that does not prefer to watch tv as also does not like to spend their time reading is 30 over 40 which can be simplified or reduced to 3 over 4. [30/40 reduced to 3/4]
Hope this somehow helped you :)
Answer:
Formula for area of triangle:
<em>A = bh x 1/2</em>
1) height is 8, and base is 8, so:
8(8) x 1/2 = 32 yd
2) height is 5, base is 6, so:
6(5) x 1/2 = 15 ft
3) height is 8, base is 10, so:
10(8) x 1/2 = 40 in
Answer:
f'(-1)= 3
Step-by-step explanation:
slope = (y2 - y1)/(x2 - x1)= (7-(-2))/(1-(-2))=9/3=3
Slope of the tangent line in the given point equals f' at this point.
So,
f'(-1)= 3
(-3, 1) y = 2/5x - 4
x₁ y₁ slope (m) = 2/5x
Since the equation we are looking for is perpendicular to y = 2/5x - 4, we need to find the opposite reciprocal slope. We have to flip the slope upside down and turn it negative.
2/5 ⇒ 5/2 ⇒ -5/2
So far, we have the equation y = -5/2.
Now, we need to find the y intercept by plugging in the given point into point slope form, which is...
y - y₁ = m(x - x₁)
The subscripts in the y and x are just the x and y in (-3,1). They are just placeholders, not exponents.
y - 1 = -5/2(x + 3)
y - 1 = -5/2x - 15/2
+ 1 + 1
------------------------------
y = -5/2x - 13/2 ⇒ final equation
