Answer:

523.1m²

Step-by-step explanation:

Triangle: 1/2bh=1/2(4)(10)=20x2=40 each

Bottom Rectangle: 15x8=120

Side Rectangles: Since the side is a hypotenuse of a right triangle, it’s the square root of 10²+4²=√116=10.77. 10.77x15=161.55

So the total surface area would be 40+40+120+161.55+161.55=523.1m²

34kurt

Answer:

The price of each movie is $2.25

The price of each video games is $5.41

Step-by-step explanation:

Given as :

Miguel rented 5 movies and 3 video games for a total cost = $27

Next day Miguel rented 2 movies and 6 video games for a total cost = $36

Let The cost of each movie = $m

And The cost of each video game = $v

Now, According to question

5 m + 3 v = 27 .....1

2 m + 6 v = 36 ...........2

Now, solving the equation

2 × (5 m + 3 v) - (2 m + 6 v) = 2 × 27 - 36

Or, 10 m + 6 v - 2 m - 6 v = 54 - 36

Or, (10 m - 2 m) + (6 v - 6 v) = 18

Or, 8 m + 0 = 18

∴ m = $\dfrac{18}{8}$ = $\dfrac{9}{4}$

i.e m = $2.25

So, The price of each movie = m = $2.25

Again, put the value of m into eq 2

So, 2 × 2.25 + 6 v = 36

Or, 4.5 + 6 v = 36

Or, 6 v = 36 - 4.5

Or, 6 v = $32.5

∴ v = $\dfrac{32.5}{6}$

i.e v = $5.41

So, The price of each video games = v = $5.41

Hence, The price of each movie is $2.25 and

The price of each video games is $5.41 Answer

What is the electric field strength at a distance of 15 cm from a point charge that has 12

ivann1987 [24]

The formula is E= kQ/ d^2

k is 9x10^9
i changed 15 cm to 0.15 m

=> 9x10^9 x 12 OVER (0.15)^2

the answer is 4.8x10^12 N/C

but this is the electric field.

to find electric field STRENGTH, it’s E= F/q and you did not give a value for the force

denis23 [38]

Answer:

2

Step-by-step explanation:

There are 6 sides:

3 by 4 = 3*4 = 12, no

3 by 3 = 3*3 = 9, no

5 by 3 = 5*3 = 15, no

Triangles:

Half of 3 by 4 = 1/2 * 3* 4 = 1/2 * 12 = 6, yes

Which expressions are equivalent to the expression below?

Dmitriy789 [7]

Given :-

-1/3 - ( -4 + 1/6 )

To Find :-

The expression that is equivalent to one of the choices given .

Solution :-

As we know that ,

→ (-) × (-) = (+)

→ (-) × (+) = (-)

→ (+) × (-) = (-)

→ (+) × (+) = (+)

On using these open the brackets ,

→ -1/3 - 1( -4 + 1/6 )

→ -1/3 - 1(-4) + -1(+1/6)

→ -1/3 (-)(-)(1* 4) (+)(-) (1*1/6)

On using now above stated rules ,

→ -1/3 +4 -1/6

Somewhat rearrange ,

→ 4 -1/3 -1/6

Take (-) as common,

→ 4 - (1/3 +1/6)

Hence Option (d) & (f) are correct .

I hope this helps.
