Answer:

The area of the prism's base in square meters is [tex]38.5m^2[/tex].

Step-by-step explanation:

The volume of a rectangular prism is found by multiplying the base of the prism by the height. Since you know that the volume is [tex]308m^3[/tex] and the height is [tex]8m[/tex], you just need to divide the volume by the height to get the area of the base, which would be [tex]\frac{308}{8}[/tex] or [tex]38.5m^2[/tex].

Answer:

Step-by-step explanation:

45 seconds = 45/60 = 0.75 minutes

7 minutes 45 seconds = 7.75 minutes

One hour = 60 minutes

Number of full laps = 60/ 7.75 = 6000/775 = 7.74

He can make 7 full laps in one hour

Answer:

  sin(θ) ≈ -0.92

  cos(θ) ≈ 0.38

  tan(θ) = -2.40

Step-by-step explanation:

Let r represent the distance of the point from the origin. The Pythagorean theorem tells us ...

  r² = (5)² + (-12)²

  r² = 169

  r = √169 = 13

The trig relations for a point on the terminal ray are ...

  (x, y) = (r·cos(θ), r·sin(θ))

Then ...

  sin(θ) = y/r = -12/13 ≈ -0.92

  cos(θ) = x/r = 5/13 ≈ 0.38

  tan(θ) = y/x = -12/5 = -2.40

Answer:0.16666

Step-by-step explanation:

As we know that

Therefore, 1/6 or 0.16666... can be written rounding off to three decimal digits such as: 0.1666... 0.167  (rounding off to three decimal digits)

Answer:

16286

Step-by-step explanation:

the formula for surface area for a sphere is 4 pi r^2

So substitute for r and you get  4pi*1296 then do 3.14 * 4 * 1296 and you get 16286.02 then round it to one decimal (it cancels out) and you get 16286.

Answer:

k = 12

Step-by-step explanation:

Given 3k = 36 we want to isolate the variable (k) using inverse operations

So we want to get rid of the 3

3k = 3 times k (multiplication)

The inverse of multiplication is division so to get rid of the * 3 we want to divide by 3. Remember whatever we do to one side we have to do to the other side so we are going to divide each side by 3

3k/3=k

36/3=12

we're left with k = 12

6) Answer: x = 5

7) Answer: x = 6

8) Answer: x = 10

9) Answer: x = 12

Answer:

(a) Pentagon

(b) Perimeter= 1435cm

Step-by-step explanation:

Given

[tex]Side\ lengths: 3.65m, 2.24m, 2.57m, 2.24m, 3.65m[/tex]

Though the question has a missing attachment, it can still be answered

Solving (a): The name of the polygon

Since we are given 5 side lengths, we can say that the polygon has 5 sides.

Such polygon is referred to as, a pentagon

Solving (b): The perimeter (in cm)

To do this, we simply add up the side lengths

[tex]Side\ lengths: 3.65m, 2.24m, 2.57m, 2.24m, 3.65m[/tex]

[tex]Perimeter= 3.65m+ 2.24m+ 2.57m+ 2.24m+ 3.65m[/tex]

[tex]Perimeter= 14.35m[/tex]

Convert to cm

[tex]Perimeter= 14.35*100cm[/tex]

[tex]Perimeter= 1435cm[/tex]

Answer:

There is no significant evidence to conclude that the mean ages of ladies getting married in Desai is different from 18.

Step-by-step explanation:

Given the data:

15,25,17,20,22,24,19,16

Using calculator :

Mean value, xbar = 19.75

Standard deviation, s = 3.69

Samoke size, n

H0 : μ = 18

H1 : μ > 18

The test statistic :

Tstatistic = (xbar - μ) ÷ (s / sqrt(n))

Test statistic = (19.75 - 18) ÷ 3.69/ sqrt(8))

Test statistic = 1.75 ÷ 1.3046

Test statistic = 1.34

The Pvalue from test statistic ; df = n - 1 = 8 - 1 = 7

Pvalue = 0.111054

Decision :

If Pvalue < α ; reject H0

0.111053 > 0.05 ` Hence, we fail to reject H0

We can conclude that, There is no significant evidence to conclude that the mean ages of ladies getting married in Desai is different from 18.

Answer:

It can therefore be noted that all angles are equal and thus the resulting triangle is actual an equilateral triangle and thus all the sides are equal. It can be concluded that the ships are 8 miles apart.

Your Answer Is 6

Step-by-step explanation:

I Got the answer 6 Because 6 x 2 = 12

Tina Walked 12 blocks and Half of 12 Is 6

Hope this helps  you!

Have a great Day!

~Rainbow~

Answer:

the correct answer is 6

Step-by-step explanation:

since twice = 2 you'll need to do 12 divided by 2

which is equal to 6.

or you can simply just think what number is twice in 12.

Answer:

4

Step-by-step explanation:

[tex] Lim_{x \to 0}\frac{2 x\sin x}{1-\cos x} [/tex]

[tex] =Lim_{x \to 0}\frac{2 x\sin x}{1-\cos x}\times \frac{1+\cos x}{1+\cos x} [/tex]

[tex] =Lim_{x \to 0}\frac{2 x\sin x(1+\cos x) }{1^2 -\cos^2 x} [/tex]

[tex] =Lim_{x \to 0}\frac{2 x\sin x(1+\cos x) }{1 -\cos^2 x} [/tex]

[tex] =Lim_{x \to 0}\frac{2 x\sin x(1+\cos x) }{sin^2 x} [/tex]

[tex] =Lim_{x \to 0}\frac{2x(1+\cos x) }{sin x} [/tex]

[tex] =Lim_{x \to 0} 2(1+\cos x) \times \frac{1}{Lim_{x \to 0}\frac{sin x}{x}} [/tex]

[tex] =2(1+\cos 0) \times 1 [/tex]

[tex] = 2(1+1) [/tex]

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

[tex] \therefore Lim_{x \to 0}\frac{2 x\sin x}{1-\cos x}= 4 [/tex]

Answer:

A, C, and D

Step-by-step explanation:

Constant of proportionality, k = y/x

Thus, all points on a line will have the same value of k.

Here, the value of k is given as ¼.

The coordinate points that will fall on a line where k = ¼, will give us the value of ¼ when we divide its y-coordinate by its x-coordinate.

Thus:

(4, 1) will give us k = y/x = ¼

(12, 3) will give us k = y/x = 3/12 = ¼

(20, 5) will give us k = y/x = 5/20 = ¼

Therefore, the options that apply are: A, C, and D
