Answer:
(1.2. - 4.7)
Step-by-step explanation:
On a coordinate plane, a line is drawn from point A to point B. Point A is at (7,-2) and point B is at (-8,-9).
Now, it is asked the x- and y-coordinates of point C, which partitions the directed line segment from A to B into the ratio 5:8.
So, the coordinates of point C are
![[\frac{5 \times (- 8) + 8 \times 7}{5 + 8}, \frac{5 \times (- 9) + 8 \times (- 2)}{5 + 8}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B5%20%5Ctimes%20%28-%208%29%20%2B%208%20%5Ctimes%207%7D%7B5%20%2B%208%7D%2C%20%5Cfrac%7B5%20%5Ctimes%20%28-%209%29%20%2B%208%20%5Ctimes%20%28-%202%29%7D%7B5%20%2B%208%7D%5D)
= ![[\frac{16}{13}, \frac{-61}{13}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B16%7D%7B13%7D%2C%20%5Cfrac%7B-61%7D%7B13%7D%5D)
= (1.2. - 4.7) (Answer)
{Round to the nearest tenth}
Answer:
Volume = 100 cm³
Surface area of the square pyramid = 145 cm²
Step-by-step explanation:
Given:
Perpendicular height = 12cm
Square length = 5cm
Find:
Volume
Surface area of the square pyramid
Computation:
Area of base = side²
Area of base = 5²
Area of base = 25 cm²
Volume = (1/3)(A)(h)
Volume = (1/3)(25)(12)
Volume = 100 cm³
Surface area of the square pyramid = A + 1/2(P)(h)
Perimeter square pyramid = 4(s)
Perimeter square pyramid = 4(5)
Perimeter square pyramid = 20 cm
Surface area of the square pyramid = 25 + 1/2(20)(12)
Surface area of the square pyramid = 145 cm²
If you divide 4.16 by 5.20 you get .8 which would be .80 cents a pound
1/2(2+a)=3a+4/3
first, you use the distributive property<span>
</span>then your problem changes to...
1 + 1/2a = 3a + 4/3
then you subtract 1/2a with 3a
1 = 2 1/2a +4/3
<span>
now you subtract 1 with 4/3
</span>
-1/3 = 2 1/2a
now you divide -1/3 with 2 1/2a
-2/15 = a
A = -2/15 is your answer. Hope this helps :)
