Which equation can be used to calculate the surface area of the rectangular prism net shown below?

Bess [88]

Answer:

$SA=\frac{1}{2}(5)(12)+\frac{1}{2}(5)(12)+(5)(10)+(12)(10)+(13)(10)$

Step-by-step explanation:

we know that

The surface area is equal to the area of all the faces of the triangular prism

$SA=\frac{1}{2}(5)(12)+\frac{1}{2}(5)(12)+(5)(10)+(12)(10)+(13)(10)$

simplify

$SA=(5)(12)+(5)(10)+(12)(10)+(13)(10)$

$SA=360\ cm^{2}$

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,160 ft Determine the flag's width and

Illusion [34]

The length of flag is 760 feet and width of flag is 320 feet

Solution:

A seed company planted a floral mosaic of a national flag

Since, the flag is generally of shape rectangle, we can use the formula of rectangle

Let "a" be the length of rectangle

Let "b" be the width of rectangle

The length is 440 ft greater than the width

Length = 440 + width

a = 440 + b ----- eqn 1

The perimeter of the flag is 2,160 ft

The perimeter of rectangle is given as:

Perimeter = 2(length + width)

Substituting the given values, we get

2160 = 2(440 + b + b)

2160 = 880 + 4b

4b = 2160 - 880

4b = 1280

b = 320

Substitute b = 320 in eqn 1

a = 440 + 320

a = 760

Thus the length of flag is 760 feet and width of flag is 320 feet

What is the scientific notation of 0.00165?

Ierofanga [76]

Answer:

The answer is $1.65*10^{-3}$

Step-by-step explanation:

when writing scientific notation, there must be one number to the left of the decimal point.

To achieve this in this problem, you need to move the decimal point 3 times to the right.

because you are moving the point to the right, the exponent will be negative.

*rule of thumb: moving the decimal to the left will give you a positive exponent, moving to the right will give you a negative exponent*

therefore you answer should be written as:

$1.65*10^{-3}$

hope this helps :)

Hector's calculator is malfunctioning. If he puts in a problem that should equal 12,his calculator says 26.If he puts in a probl

Gennadij [26K]

Answer:

Doubling the actual answer and increasing it by 2.

Step-by-step explanation:

The calculator is returning 26, instead of 12. Note that 26 is 2 more than twice of 12.

i.e.

26 = 2(12) + 2

Calculator is returning 32 instead of 15. Here again we can note the same logic. 32 is 2 more than twice of 15.

i.e.

32 = 2(15) + 2

Calculator returns 202 instead of 100. Here again the same logic holds true.

i.e.

202 = 2(100) + 2

So, what the calculator is doing is:

Doubling the actual result and increasing it by 2.
