What the lateral and surface area of this figure

tamaranim1 [39]

Answer:

Lateral Surface Area = 314^2 inch = 314.86 square inch

To find Lateral Area

First we square two of the sides of the top to find the hypotenuse which is also the height of the side triangles.

Here we take 5^2 6^2 = 25 +36 = 61

as a decimal √61 ≈ 7.8102

7.8102 x 5 = 39.051 is the Surface area of the top of the shape we will call this p.

Therefore Surface area =, b x h + p x l = 30 x 3 =90 + (40.81 x 6)

=224.86 +90 = 314.86^2 inch = Lateral SA

p= b+h+c = 5 x 6 =30 + 3 + 7.81 = 40.81sq2

Step-by-step explanation:

6 x 5 =35 x 2 = 70

3 x 5 =15 x 2 = 30

6 x 3 = 18 x 2 = 36

Area only if base and top was the same = +136cm^2

This area is invalid. So it is really important to learn hypotenuse.

Volume is much easier and can guide you for reverse workings more for same sides. The shape above has not got the same sides. There is no surface area only lateral area at top.

V= 45^3inch = 45 cube inch

Just like a rectangle box but half its size as all opposite sides are the same. and the top and base can create a square by using the sides.

To do ths we half the end area.

6 x 3 x 5 = 18 x 5 = 90 sq3

half of this is 45 cube inch volume.

The amount of money in a bank account increased by 15.8% over the last year. If the amount of money at the beginning of the year

Lostsunrise [7]

Answer:

The expression represents the amount of money in the bank account after the increase is: x=1.158n.

Step-by-step explanation:

With the information provided, you can say that the amount of money in the bank after the increase would be equal to multiplying the amount at the beginning of the year for the result of adding up 1 plus the percentage of the increase, which would be:

x=n*(1+0.158)

x=n*1.158

x=1.158n, where:

x is the amount of money in the bank account after the increase

n is the amount of money at the beginning of the year

Find all the values of k so that the given points are 29 square units apart. (-5, 5) and (k,0).

Varvara68 [4.7K]

Distance formula between 2 points (x1,y1) and (x2,y2)

D= $\sqrt{(x1-x2)^{2}+(y1-y2)^{2}}$

D=29 and one point is (-5,5) and the other is (k,0)
sub

29= $\sqrt{(-5-k)^{2}+(5-0)^{2}}$
29= $\sqrt{(-5-k)^{2}+(5)^{2}}$
square both sides
841= $(-5-k)^{2}+(5)^{2}$
841= $(-5-k)^{2}+25$
minus 25 both sides
816= $(-5-k)^{2}$
square root both sides don't forget positive and negative roots
+/-4√51=-5-k
add 5 to both sides
5+/-4√51=-k
times -1 both sides
-5+/-4√51=k

the possible values for k are
k=-5+4√51 or k=-5-4√51
