Answer:

The surface area is 48cm^2

Step-by-step explanation:

Given

Dimension: 2cm by 2cm by 5cm

Shape: Rectangular Prism

Required

Determine its Surface Area (A)

This is calculated as thus:

[tex]A = 2(lw + lh + hw)[/tex]

Where l, w and h are the dimensions of the given shape:

We can say:

[tex]l = length = 2cm[/tex]

[tex]w=width = 2cm[/tex]

[tex]h=height=5cm[/tex]

So:

[tex]A = 2(2 * 2 + 2 * 5 + 5 * 2)[/tex]

[tex]A = 2(4 + 10 + 10)[/tex]

[tex]A = 2(24)[/tex]

[tex]A = 2 * 24[/tex]

[tex]A = 48[/tex]

Hence, the surface area is 48cm^2

D is incorrect because two vertically opposite angles HAVE to be equal there for D is false.

Step-by-step explanation:

We know that 6 times 9 is 54.

Now, 9 times 6 is also 54.

The order of multiplication do not matter.

Answer:

B.

Step-by-step explanation:

9 (x + 1) = 9*x + 9*1 = 9x + 9

Answer:

D. 58,905

Step-by-step explanation:

Number of seats available for Mr. Jones had for the trip = 4

Number of students in his class = 36

Number of ways he can select a group of 4 out of 36 students from his class is calculated as follows:

[tex] C \binom{36}{4} = \frac{36!}{(36 - 4)! * 4!)} [/tex]

[tex] = \frac{36!}{(32! * 4!)} = 58,905 [/tex]

Answer:

-1

Step-by-step explanation:

dy/dt = y² − 1 = (y + 1) (y − 1)

At t = 0, y = 0, and dy/dt = -1.  Therefore, y is initially decreasing.

As y decreases, dy/dt increases.  When y = -1, dy/dt = 0 and changes signs from negative to positive.

As y increases above -1, dy/dt again becomes negative.  So y continues to approach -1 as t approaches infinity.

Answer:

Number of peolpe= 14

Step-by-step explanation:

Giving the following information:

Total weight= 2,100 pounds

Average weight= 150 pounds

To calculate the number of people that can ride the elevator at the same time, we need to use the following formula:

Number of people= total weight / average weight

Number of peolpe= 2,100/150

Number of peolpe= 14

Answer:

28.26m^2 (aka. 28.26 meters squared)

Step-by-step explanation:

The area of a circle is A=pi*r^2 where r is the radius of the circle.

Since r=3, then A=pi*3^2=9pi=28.26

Therefore, the area of the merry-go-round is 28.26 square meters

D. 50º

Step-by-step explanation:

According to the image below attached, blue lines represents line segments [tex]DB[/tex] and [tex]DB'[/tex], the red line creates a right angle regarding [tex]DB[/tex] (90º), where green line creates a flat angle with the same respect (180º). The angle between [tex]DB[/tex] and [tex]DB'[/tex] is less than 90º and 180º, meaning an acute angle. Therefore, the right answer is D.

Answer:-5y=-3x+10

Divide all by -5

Answer:

b

Step-by-step explanation:

significant figures means counting the digits that either come before a trail of zeros (45.0000 has 7 significant figures) or come after a trail of leading zeros (00.31 has two significant figures, because the zeros before the decimal point have no other digit in front of them and do not count) 1005.0 would have 6 significant figures

Answer:

4/9>7/15

Step-by-step explanation:

Answer:

k=45

Step-by-step explanation:

the k on the right can be mirrored from the left side of the triangle, the other side of the triangle says that its 45 degrees so that means the answer is as well, but if you want to make sure that the answer is correct then take the 2k degrees then replace the k with 45 and multiple that which gives you 90. add the other 2 45s together which gives you another 90 and then add the two 90s which gives you 180.
