Step-by-step explanation:

[tex]\left(\dfrac9{10}+\dfrac25\right)\div\left(\dfrac{11}{6}\cdot\dfrac59\right)\ =\ \left(\dfrac9{10}+\dfrac4{10}\right)\div\dfrac{55}{54}=\\\\\\ =\ \dfrac{13}{10}\times\dfrac{54}{55}\ =\ \dfrac{13}{5}\times\dfrac{27}{55}\ =\ \dfrac{351}{275}[/tex]

Answer:

The answer is D.

Step-by-step explanation:

A. 8^3 x 8^2 < 8^4

8^3 = 512    8^2 = 64       512 x 64 = 32768

8^4 = 4096                  32,768 < 4096 is NOT true

B. 4^4 x 4^4 = 4^16

4^4 = 256       256 x 256 = 65536

4^16 = 4294967296

256 = 4294967296   is NOT true

C. 2^2 • 2^6 < 2^8

2^2 = 4     2^6 = 64    64*4 = 256

2^8 = 256             256 < 256   is NOT true

D. 3^3 • 3^3 > 3^5​

3^3 = 27    27*27 = 729

3^5 = 243

729 > 243 IS true

The height of the flat screen TV can be calculated by dividing the given area (21 square feet) by the given width (3 feet). This gives us a height of 7 feet.

In this problem, we are given the area of the flat screen TV and the width. The area of a rectangle is calculated by multiplying the width and the height, so to find the height, we can divide the area by the width.

Let's denote the height as 'h'. So, the formula will be: Width times height = Area of the screen, or in our case, 3 feet times h = 21 square feet. Solving this equation gives us h = 21 ÷ 3 = 7 feet.

So, the height of the TV is 7 feet.

Answer:

A. 15%

Step-by-step explanation:

percent change = (new number - old number)/(old number) * 100%

The new number is the increased area, 25,587.5 sq yd, and the old number is the original area, 22,250 sq yd.

percent change = (25,587.5 sq yd - 22,250 sq yd)/(22,250 sq yd) * 100%

percent change = (3,337.5 sq yd)/(22,250 sq yd) * 100%

percent change = 0.15 * 100%

percent change = 15%

Since the percent change is a positive number, it is a percent increase.

The percent increase was 15%.

Answer:

$24.4

Step-by-step explanation:

We are given that a discount store promises that all items it sells are 40% of their normal asking retail price.

If a shoes have a retail price of $60.99, we are to find the expected price of the shoes at this store.

Expected price of shoes = 40% of $60.99 = [tex] \frac { 4 0 } { 1 0 0 } \times 6 0 . 9 9 [/tex] = $24.4

The answer is 16

The Pythagorean theorem is a^2+b^2=c^2

You already have one side and the hypotenuse (c)

15^2+b^2=17^2

15^2= 225

17^2= 289

Now you have 225+b^2= 289

Subtract 225 from both sides and you get

b^2=64

Then take the square root of both sides to get b alone

b=8

Now, since the base of the inner triangle is half of the base of the pyramid, multiply your answer by 2

You will get 16

ANSWER

The second term is 7.

EXPLANATION

The given sequence has it's first term to be:

[tex]t_1 = 3[/tex]

The recursive definition is :

[tex]t_{n+1}=2t_n+n[/tex]

To find the second term , we substitute n=1,

to obtain,

[tex]t_{1+1}=2t_1+1[/tex]

This implies that:

[tex]t_{2}=2t_1+1[/tex]

[tex]t_{2}=2(3)+1[/tex]

Simplify:

[tex]t_{2}=6+1[/tex]

[tex]t_{2} = 7[/tex]

Answer:

The second term of the sequence is 7 ⇒ the 2nd answer

Step-by-step explanation:

* Lets revise the recursive formula

1. Determine if the sequence is arithmetic (Do you add, or subtract, the

  same amount from one term to the next?)

2. Find the common difference. (The number you add or subtract.)

3. Create a recursive formula by stating the first term, and then stating

   the formula to be the previous term plus the common difference.

   a1 = first term;

   an+1= an + d

- Where:

# a1 = the first term in the sequence

# an = the nth term in the sequence  

# an+1 = the term after the nth term  

# n = the term number

# d = the common difference.

* Now lets solve the problem

∵ The recursive definition is tn+1 = 2 tn + n and t1 = 3

- Lets find the 2nd term

∵ t1 = 3

∵ tn+1 = 2 tn + n

* To find the second term put n = 1

∴ t2 = 2 (3) + 1

∴ t2 = 6 + 1 = 7

∴ t2 = 7

* The second term of the sequence is 7

Answer:

1= 115

2=45

3=110

4=115

5=115

Step-by-step explanation:

Answer:

1:

[tex]180-(70+45)=65[/tex] degrees(3rd angle of triangle)

Angle 1 is [tex]180-65=115[/tex] degrees.

2:

Angle 2 is 45 degrees as vertically opposite is also 45 degrees.

3:

[tex]180-(65+45)=70[/tex] degrees(third angle of lower triangle)

Its opposite will also be 70 degrees.

So, 3rd can be found as : [tex]360-(70+110+70)=110[/tex] degrees

You can also say that 3 is vertically opposite of 110 degrees.

4:

[tex]180-65=115[/tex] degrees

To find the value of 'a' for which the line x = a splits the region into two equal areas, integrate the curve starting from -sqrt(a+1) to sqrt(a+1) and set it equal to the area of the region between the curve and the y-axis.

This question pertains to the concept of finding the area under curves in Calculus. To solve this problem, we need to set up an equation that represents the given situation and solve for 'a'. The line 'x = a' splits the region into two equal areas, meaning the area on the right of the line is equal to the area on the left of the line.

Starting from the x-axis, the curve 'x = y^2 - 1' intersects the line at y = sqrt(a+1) and y = -sqrt(a+1). Thus, we want the integral from -sqrt(a+1) to sqrt(a+1) of the curve to be equal to the area of the region between the curve and the y-axis. Formulate and solve the intergral problem to get the desired value of 'a'.

Additionally, this problem might involve the use of numerical methods like the Simpson's rule or midpoint rule to get an accurate result.

Cir=30π=2πr , thus r=15 , Area=π(r^2)=225 pie meters

The area of circle is 225π m².

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle possesses rotational symmetry around the center.

Given that,

Circumference of the circle = 30π m

Let r be the radius of circle.

Since we know that,

circumference of the circle = 2πr

Therefore,

⇒  2πr = 30π

⇒       r = 15 m

Area of circle = πr²

                      = (15)²π

                      = 225π

The correct answer is option C.   16√2

Step-by-step explanation:

Points to remember

If the angles of a right angled triangle are 45°, 45° and 90° then the sides of the triangles are in the ratio 1 : 1: √2

To find the length of each leg of triangle

From the figure we can see that a right angled triangle with angles 45°, 45°, 90° and hypotenuse = 32

Therefore the sides are in the ratio 1 : 1 :√2

Leg1 : Leg2 : hypotenuse = 1 : 1 : √2 = x : x : 32

Therefore x = 32/√2 = 16√2

So the correct answer is option C.   16√2

The probability that Chloe is awarded a blue ribbon in both January and February is 0.1421 or  14.21%.

To calculate this, we simply multiply the probabilities of Chloe being awarded a blue ribbon in January and February:

Probability in January = 0.29

Probability in February = 0.49

Probability in January and February = 0.29 * 0.49 = 0.1421

Explanation:

1. Given probabilities:

  - Probability of Chloe being awarded a blue ribbon in January = 29% = 0.29

  - Probability of Chloe being awarded a blue ribbon in February = 49% = 0.49

2. To find the probability of Chloe being awarded a blue ribbon in both January and February, we multiply the probabilities together:

  - Probability in January and February = 0.29 * 0.49 = 0.1421

Therefore, the probability that Chloe is awarded a blue ribbon in both January and February is approximately 14.21%.

To find out how long it would take Petra to jog 13 miles at the same rate, we can set up a proportion and solve for the unknown variable. The answer is approximately 156 minutes.

To find out how long it would take Petra to jog 13 miles at the same rate, we can set up a proportion using the given information. Since Petra jogs 2 miles in 24 minutes, the rate at which she jogs is 2 miles / 24 minutes. We can use this rate to find out the time it would take her to jog 13 miles.

Set up the proportion: 2 miles / 24 minutes = 13 miles / x minutes. Cross multiply and solve for x to find the answer.

2 miles / 24 minutes = 13 miles / x minutes
2x = 24 × 13
2x = 312
x = 156

So, it would take Petra approximately 156 minutes to jog 13 miles at the same rate.

Option A. ∠ACE is supplementary to ∠BCD

False. They are not lying on a point of straight line.

∠ACE + ∠BCD ≠180°

Option B. ∠BCE is supplementary to ∠ACE

Since ∠ACD + ∠ACE = 180° [Given]
