2. 8x² - 16y²

3. 25m² + 100n²

4. 100 [tex]a^4[/tex] - 9 [tex]b^{12[/tex]

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)

Given:

we have to find expression for difference of two squares

1. 4g - 16h

= (2)²g- (4)²h

2. 8x² - 16y²

= (2√2x)² - (4y)²

3. 25m² + 100n²

= (5m)² + (10n)²

4. 100 [tex]a^4[/tex] - 9 [tex]b^{12[/tex]

Answer:

A) x=2

Step-by-step explanation:

Answer:

8/12

Step-by-step explanation:

Given that:

Dividing into 12 steps

Total step, fraction = 1

Each of the 12 steps = 1/12

If two steps is completed in one day:

. Steps completed per day :

2 (1/12)

= 2 /12 steps per day

Fraction of steps completed after 4 days

Fraction of steps per day * number of days

2 /12 * 4

(4*2) / 12

Answer:

13% of 44,000

Do the math then you’ll get the answer :)

Answer:

$12,183.60

Step-by-step explanation:

(I am assuming this is monthly interest and not continuous interest)

$44,000(1.13)² = $44,000(1.2769) = $56,183.60 - $44,000 = $12,183.60

Expression is; 29 - x = 16

Step-by-step explanation:

I've attached an image showing the number line

Step-by-step explanation:

We are told that at lunchtime, it was 29 degrees Celsius and that by sunset, the temperature had dropped to 16 degrees Celsius.

Let the drop be x.

Thus;

29 - x = 16

Answer:

5

Step-by-step explanation:

As we can see they are similar triangles then

the ratio of the corresponding sides are equal then

x /25 = 9/45

x = 25 * 1/ 5

x = 5

Answer: The artist used 8.6 inches more of silver wire

Step-by-step explanation:

Perimeter of the square

P = 4*a

P = 4*a = 40 in

a = 10 in

Each side of the square has a length of 10 in

The diameter of the circle is equal to the length of the side of the square

Diameter = 10 in

Perimeter of the circle

P_c = 2*π*radius = π*diameter

P_c = (3.14)*10 in = 31.4 in

Inches of silver wire (square) = 40 in

Inches of copper wire (circle) = 31.4 in

40- 31.4 in = 8.6 in

Answer:

The most appropriate inferential statistic test in the present situation is the;

b. Two-sample t-test

Step-by-step explanation:

From the question, we have;

The number of subjects in each sample, n₁ = 100

The number of samples = 2

The nature of the test = To compare the two means

The value of the population standard deviation, σ = Unknown

From the given parameters, we have;

The t-test is a method of inferential statistics for determining whether the difference between the mean of two groups is significant, that is if the observed difference are due to chance, where the groups are likely to have some characteristics that are related

The t-test is utilized when testing an hypothesis, and it is used for small samples, where the population standard deviation is unknown

The types of t-test used are;

a) One-sample t-test

b) Two-sample t-test

c) Paired Sample t-test

Therefore, a two-sample t-test is most appropriate.

Answer:

Part A)

The lower base has a radius of 9 units, and the upper base has a radius of 6 units.

Part B)

5 units.

Part C)

75π or about 235.62 square units.

Step-by-step explanation:

Please refer to the figure below.

The cone has a radius of 9 units and a total height of 12 units.

A frustum of the cone has a height of 4 units.

Part A)

The lower radius of the frustum will simply be 9 units.

For the upper radius, we will use the properties of similar triangles. We will compare the smaller upper triangle to the overall larger triangle. This yields:

[tex]\displaystyle \frac{12}{8}=\frac{9}{x}[/tex]

Solve for x. Simplify:

[tex]\displaystyle \frac{3}{2}=\frac{9}{x}[/tex]

Cross-multiply:

[tex]18=3x\Rightarrow x=6[/tex]

The upper base has a radius of 6 units.

Part B)

We can first find the total slant height of the entire cone. By using the Pythagorean Theorem, this yields that the total slant height is:

[tex]SH^2=12^2+9^2[/tex]

Simplify:

[tex]SH^2=225\Rightarrow SH=15\text{ units}[/tex]

Now, find the slant height of the upper cone:

[tex](SH_\text{cone})^2=8^2+6^2=100[/tex]

So:

[tex]SH_\text{cone}=10[/tex]

Then the slant height of the frustum will be the cone subtracted from the total. Thus:

[tex]SH_{\text{frustum}}=15-10=5\text{ units}[/tex]

Part C)

We can first find the lateral area of the entire cone. The lateral area is given by:

[tex]LA=\pi r\ell[/tex]

The lateral area of the entire cone will be:

[tex]LA=\pi (9)(15)=135\pi[/tex]

The lateral area of the upper cone will be:

[tex]LA_\text{cone}=\pi(6)(10)=60\pi[/tex]

Then the lateral area of the frustum is:

[tex]LA_\text{frustum}=135\pi-60\pi =75\pi\text{ units}^2\approx235.62\text{ units}^2[/tex]

Answer:

the correct answer is 126 sq. cm

Step-by-step explanation:

Area of square= side = 6cm

Area = s*s = 6*6 = 36sq. cm

Area of rectangle: length = 12cm and breadth = 6cm

Area of rectangle = length * breadth = 12 * 6 = 72sq. cm

Area of triangle: height = 6cm and base = 6cm

Area of triangle = 1/2 * base * height = 1/2 * 6 * 6 = 3* 6 = 18sq. cm

Total area of the given figure = Area of square + Area of rectangle + Area of triangle

= 36 + 72 + 18 = 126sq. cm
