Answer:. 1/2
Step-by-step explanation: Different ways to get this.
PEMDAS: figure 8 squared is 64 and 2 cubed is 8. Multiply to get 512 in the numerator.
Figure 4 cubed is 64 and (-2)^4=16. Multiply to get 1024 in the denominator. Simplify to 1/2
You could express all the factors as 2 to some power then add and subtract the exponents.
2^6 •2^3=2^9. Over
2^6 • 2^4 = 2^10. Subtract exponents. 2 to the -1 power is 1/2.

20 pts!! Find the total surface area of this prism.
___ square meters
Answers
Answer:
38m^2
Step-by-step explanation:
We are solving the surface area of a rectangular prism that has been cut in half diagonally.
Our equation for this is
S = 2(lw + lh + wh)
Plug in our info
S = 2(10(1.5) + 10(2) + 1.5(2))
Work inside parentheses
S = 2(15 + 20 + 3)
S = 2(38)
S = 76
Our original surface area would be 76 if this were a regular rectangular prism, but its not! It's cut in half.
So, 76/2 is 38.

The area of triangle ABD is 50cm, and one of its sides is 10cm in length. Find one of the heights of the triangle.
Answers
Answer:
10cm
Step-by-step explanation:
If you want to find one of the heights of the triangle, you need to use some math magic. The magic spell is:
A = (1/2) * b * h
where A is the area, b is the base, and h is the height. Don't ask me why, it just works.
Now, we know that the area of triangle ABD is 50 cm and one of its sides is 10 cm. We can pretend that this side is the base of the triangle. Why? Because it makes our life easier. Trust me.
Then we put these numbers into the magic spell and we get:
50 = (1/2) * 10 * h
Now we need to solve for h, which is the height we want. To do that, we need to do some algebra. Don't worry, it's not that hard. Just follow these steps:
- Multiply both sides by 2. This gives us:
100 = 10 * h
- Divide both sides by 10. This gives us:
10 = h
- Celebrate! We found the height!
So, one of the heights of the triangle is 10 cm. Isn't math fun?
Area of triangle = 1/2 × base × height
We know the area of the triangle is 50 cm², and one of the sides (which is also the base) is 10 cm. Let's substitute these values in the formula and solve for the height:
50 = 1/2 × 10 × height
Multiplying both sides by 2, we get:
100 = 10 × height
Dividing both sides by 10, we get:
height = 10 cm
Therefore, the height of triangle ABD is 10 cm.

Player A is the most consistent, with an IQR of 1.5.
Player A is the most consistent, with a range of 5.
Answers
Answer: Player B is the most consistent, with an IQR of 3.5.
Step-by-step explanation:
For Player A, the IQR is 2 (Q3 - Q1 = 3 - 1 = 2).
For Player B, the IQR is 3.5 (Q3 - Q1 = 5 - 1.5 = 3.5).
Therefore, Player B is more consistent, as their IQR is larger, indicating less variability in their scores.

The sum of 2.54 x 10¹⁹ and 3.218 x 10¹⁷ will be 2.57218 x 10¹⁹ so option (D) will be correct.
What is summation?A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation. There could be only two terms, but there could be one hundred, thousand, or a million. There are summations with an infinite set of parameters.
In another word, the summation is to add or subtract any two or more terms by doing that operation we will get a new result which could be big or small depending upon the number.
Given the digits are
2.54 x 10¹⁹ and 3.218 x 10¹⁷
Now in order to sum we need to make an equal exponent of 10
So,
2.54 x 10¹⁹ = 254 x 10¹⁷
Now, Summation
254 x 10¹⁷ + 3.218 x 10¹⁷
257.218 x 10¹⁷ = 2.57218 x 10¹⁹
Hence "The sum of 2.54 x 10¹⁹ and 3.218 x 10¹⁷ will be 2.57218 x 10¹⁹ so option (D) will be correct".

Q1) 80% of a dog's mass is equal to 24% of the mass of a lion. If the mass of the lion is 105 kg more than the mass of the dog, find the total mass of the dog and the lion.
Answers
We are given that 80% of the dog's mass is equal to 24% of the lion's mass. Mathematically, this can be expressed as:
0.80D = 0.24L
We are also given that the mass of the lion is 105 kg more than the mass of the dog:
L = D + 105
We can use these two equations to find the values of D and L.
Substituting the value of L from the second equation into the first equation:
0.80D = 0.24(D + 105)
Now, let's solve for D:
0.80D = 0.24D + 0.24(105)
0.80D - 0.24D = 25.2
0.56D = 25.2
D = 25.2 / 0.56
D ≈ 45
Now that we have the value of D, we can find the value of L by substituting it back into the second equation:
L = 45 + 105
L = 150
Therefore, the total mass of the dog and the lion is:
D + L = 45 + 150 = 195 kg
So, the total mass of the dog and the lion is 195 kg.

Ruth's dining room is 6 yards wide and 9 yards long. Ruth wants to install a new wood floor. It will cost $8.00 per square yard. How much will Ruth's new floor cost?
Answers
Ruth’s new floor cost $432.
The cost can be calculated as follows.
First, calculate the area of dining room. Use the formula of rectangle area (width x length)
Area = width x length
= 6 yd x 9 yd
= 54 sq yd
Second, calculate the total cost.
Cost = 54 sq yd x $ 8 per sq yd
= $ 432
Hence it cost $ 432 to install the new wood floor.

What is the area of the rectangle?
The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.
The area of the rectangle is calculated by the formula below:-
Area = Length x Width
Area = 4⁴/₄ x 7⁵/₆
Area = (18 / 4) x ( 47 / 6 )
Area = 141 / 4
Area = 35⁵/₂₄ square meters
Therefore, the area of the rectangle will be 35⁵/₂₄ square meters.

Total lateral surface of the pyramid is: \(11.25 \,\,cm^2\)
which agrees with the second option shown among the list of possible answers
Step-by-step explanation:
The total surface area of this square based pyramid consists of the addition of four triangles (the four lateral faces) of base 1.5 cm and height 3 cm, plus the area of its square base (1.5 cm x 1.5 cm).
Recall that the area of a triangle is defined as the product of its base time its height, divided by two. So the total surface for this pyramid is:
\(Total\,\,Area= 4\,*\,Area_{triangle}+Area_{square}\\Total\,\,Area= 4\,* \frac{1.5\,*\,3\,}{2} +1.5^2\\Total\,\,Area= 9\,+2.25 \,\,cm^2\\Total\,\,Area= 11.25 \,\,cm^2\)
