Answer: [tex]245cm^{2}[/tex]

Step-by-step explanation:

The formula for calculating the area of a square is given by :

Area = [tex]l^{2}[/tex]

where [tex]l[/tex] is the length of a side .

Therefore , the area of one of the square given implies :

Area = [tex]7^{2}[/tex]

Area [tex]= 49[/tex]

And since there are 5 squares in all , the area will therefore be :

Area = [tex]5[/tex] x[tex]49[/tex]

Area = [tex]245cm^{2}[/tex]

Therefore: the area of the shape is [tex]245cm^{2}[/tex]

Answer:

The height of the flagpole is 25 foot.

Step-by-step explanation:

Given:

Height of the stick = 5 foot

Shadow of the stick = 4 foot

Another one:

Height of the flagpole = 'x'

Shadow of the flagpole = 20 foot

Note:The shadows are formed at the same time of the day so the Sun makes an equal angle with both the situation.

Here from both ends it forms two similar triangles.

So,

We can say that:

⇒ [tex]\frac{Height\ of\ the\ flagpole}{Shadow\ of\ the\ flagpole}=\frac{Height\ of\ the\ stick}{Shadow\ of\ the\ stick}[/tex]

⇒ [tex]\frac{x}{20}=\frac{5}{4}[/tex]

⇒ [tex]\frac{x}{20}\times 20=\frac{5}{4}\times 20[/tex]

⇒ [tex]x=25[/tex] foot

So Darius estimated height of the flagpole = 25 foot.

Answer:

The length of the base the pyramid is 116 feet.

Step-by-step explanation:

See the diagram attached to this answer.

Let Δ OAB is the side triangle of the square pyramid, and A'B' is the mid segment parallel to the ground with length of 58 feet.

Now, Δ OAB and Δ OA'B' are similar triangle and the length of sides of the triangle Δ OA'B' are in the same ratio with the corresponding sides of Δ OAB.

Hence, [tex]\frac{OA'}{OA} = \frac{OB'}{OB} = \frac{A'B'}{AB} = \frac{1}{2}[/tex]

⇒ AB = 2 × 58 = 116 feet.

The length of the base the pyramid is 116 feet. (Answer)  

Final answer:

The length of the base of the pyramid in question, referenced as the Great Pyramid of Cheops, is historically known to be 230 meters on each side.

Explanation:

The student's question relates to finding the length of the base of a pyramid with a known mid-segment length in one of the triangular faces.

Answer:

D.) A 90 degree clockwise rotation about the origin

Step-by-step explanation:

The red triangle should have a 90° clockwise rotation about the origin. Option C is correct.

Given that,
A graph of figures is shown in the pictures,
Which transformation of the red triangle on the graph maps it onto the missing piece of the square is to be determined.

The translation is defined as the change of position through linear distance and angle.

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

In order to occupy the required space on the green figure by red triangle, it should be rotated to 90° clockwise about the origin.

Thus, the red triangle should have a 90° clockwise rotation about the origin. Option C is correct.

Answer:

7.1ft

Step-by-step explanation:

The formula for calculating the total surface area of a cube is 2(L²+L²+L²)

=2(3L²)

= 6L²

Where L is the length of the cube

If the total surface area of a cube is 302.46ft², then

302.46 = 6L²

L² = 302.46/6

L² = 50.41

L =√50.41

L = 7.1ft

The length of the side of the cube is 7.1ft

The length of the side of the cube is approximately [tex]\( 7.1 \, \text{ft} \).[/tex]

To find the length of the side of a cube given its total surface area, we need to use the formula for the surface area of a cube.

The formula for the surface area of a cube is:

[tex]\[ \text{Surface Area} = 6s^2 \][/tex]

where s is the length of a side of the cube.

Given the total surface area is [tex]\( 302.46 \, \text{ft}^2 \)[/tex], we can set up the equation:

[tex]\[ 6s^2 = 302.46 \][/tex]

To solve for s we first divide both sides by 6:

[tex]\[ s^2 = \frac{302.46}{6} \][/tex]

[tex]\[ s^2 = 50.41 \][/tex]

Next, we take the square root of both sides to find s

[tex]\[ s = \sqrt{50.41} \][/tex]

[tex]\[ s \approx 7.1 \, \text{ft} \][/tex]

Thus, the length of the side of the cube is approximately [tex]\( 7.1 \, \text{ft} \).[/tex]

Answer:

The answer is A)$10.50

Step-by-step explanation:

In order to solve the average amount, you have to add the total amount of money spent and divide it by the total number of times you spent money on food. The total sum of money spent was $63. If you divide that by how many times you ate (6 times) you'll get the dividend/answer of 10.5.

Hope this helps :)

You are spending, on average, A) $10.50 per day on food.

The correct answer is A) $10.50.

To find the average amount spent per day on food, you need to add up the total amount spent over the 6 days and then divide it by the number of days (6).

Total amount spent on food = $8 + $14 + $12 + $11 + $5 + $13

                                               = $63

Average amount spent per day = Total amount spent / Number of days

                                                     = $63 / 6

                                                     = $10.50

So, you are spending, on average, $10.50 per day on food.

Answer:

0.039

Step-by-step explanation:

To solve the equation, you need to isolate/get "y" by itself in the equation:

3y - 4 = 6 - 2y        Add 2y on both sides

3y + 2y - 4 = 6 - 2y + 2y

5y - 4 = 6        Add 4 on both sides

5y - 4 + 4 = 6 + 4

5y = 10          Divide 5 on both sides

[tex]\frac{5y}{5} =\frac{10}{5}[/tex]

y = 2

PROOF

3y - 4 = 6 - 2y        Substitute/plug in 2 for y

3(2) - 4 = 6 - 2(2)

6 - 4 = 6 - 4

2 = 2

After Solving the equation for 3y-4=6-2y, we get y = 2. We must isolate the variable y on one side of the equation in order to get the solution to the equation 3y - 4 = 6 - 2y. Here's a step-by-step procedure:

Start by solving 3y - 4 = 6 - 2y, which is the provided problem.

Add 2y to both sides of similar phrases to combine them: 3y + 2y - 4 = 6 - 2y + 2y.

Simply put, this is: 5y - 4 = 6.

Add 4 to both sides of the variable word to isolate it: 5y - 4 + 4 = 6 + 4.

This may be summarised as 5y = 10.

To find y, multiply both sides of the equation by 5. (5y) / 5 = 10 / 5.

This may be condensed to: y = 2.

Consequently, y = 2 is the answer to the equation 3y - 4 = 6 - 2y.

(c) [tex]\sum_{n=1}^{4}(n+1) ![/tex]

(d) [tex]\sum_{n=2}^{5} n ![/tex]

Answer:

Option a: [tex]\sum_{n=2}^{5}(n-1) ![/tex] is the correct answer.

Explanation:

Option a: [tex]\sum_{n=2}^{5}(n-1) ![/tex]

By substituting the values of n and expanding the summation, we have,

[tex](2-1) !+(3-1) !+(4-1) !+(5-1) ![/tex]

Subtracting, we have,

[tex]1 !+2!+3 !+4 ![/tex]

Expanding the factorial,

[tex]1+(2*1)+(3*2*1)+(4*3*2*1)[/tex]

Simplifying, we get,

[tex]1+2+6+24[/tex]

Thus, the summation [tex]\sum_{n=2}^{5}(n-1) ![/tex] represents the series [tex]1+2+6+24[/tex]

Hence, Option a is the correct answer.

Option b: [tex]\sum_{n=0}^{3} n ![/tex]

By substituting the values of n and expanding the summation, we have,

[tex]0!+1!+2!+3![/tex]

Expanding the factorial,

[tex]0+1+(2*1)+(3*2*1)[/tex]

Simplifying, we get,

[tex]0+1+2+6[/tex]

Thus, the summation [tex]\sum_{n=0}^{3} n ![/tex] does not represents the series [tex]1+2+6+24[/tex]

Hence, Option b is not the correct answer.

Option c: [tex]\sum_{n=1}^{4}(n+1) ![/tex]

By substituting the values of n and expanding the summation, we have,

[tex](1+1) !+(2+1) !+(3+1) !+(4+1) ![/tex]

Adding, we have,

[tex]2!+3!+4!+5![/tex]

Expanding the factorial,

[tex](2*1)+(3*2*1)+(4*3*2*1)+(5*4*3*2*1)[/tex]

Simplifying, we get,

[tex]2+6+24+120[/tex]

Thus, the summation [tex]\sum_{n=1}^{4}(n+1) ![/tex] does not represents the series [tex]1+2+6+24[/tex]

Hence, Option c is not the correct answer.

Option d: [tex]\sum_{n=2}^{5} n ![/tex]

By substituting the values of n and expanding the summation, we have,

[tex]2!+3!+4!+5![/tex]

Expanding the factorial,

[tex](2*1)+(3*2*1)+(4*3*2*1)+(5*4*3*2*1)[/tex]

Simplifying, we get,

[tex]2+6+24+120[/tex]

Thus, the summation [tex]\sum_{n=2}^{5} n ![/tex] does not represents the series [tex]1+2+6+24[/tex]
