Fun question: Which animal do you think is the smartest animal in the world. Whoever has the most detailed response gets a Brainlist. This is not a right or wrong question!!

Answer:

400

Step-by-step explanation:

The surface area is found when adding the areas of all the squares in the prism. 5x10=50, and we have that square twice, so 100. Again, 5x10=50, and we have that twice, so another 100. Then, 10x10, which is 100, and we have two of those, so 200. 100+100+200=400

Hope that helped, have a nice day!

Answer:

A. 400cm²

Step-by-step explanation:

The jewelry box is a rectangular prism.

Formula for surface area of a rectangular prism:

A = 2(w*l+h*l+h*w)

Plug in the numbers:

A = 2(10*10+5*10+5*10)

A = 400

Answer:

Value of ∠1 = 102°

Value of ∠1 = 72°

Step-by-step explanation:

Given:

∠ S = 42°

∠ A = 30°

Find:

Value of ∠1

Value of ∠2

Computation:

Using angle sum property;

Sum of all interior angle of a triangle = 180°

∠ S + ∠ A + ∠ 1 = 180

42 + 30  + ∠ 1 = 180

72 + ∠ 1 = 180

∠ 1 = 180 - 72

∠ 1 = 102

Value of ∠1 = 102°

∠ 1 and ∠ 2 makes a straight line

So,

∠ 1 + ∠ 2 = 180  

102 + ∠ 2 = 180  

∠ 2 = 180 - 102

∠ 2 = 72

Value of ∠1 = 72°

Answer:

[tex]x=12\times \text{tan}(20^0)[/tex]

Step-by-step explanation:

From the figure attached,

Measure of an angle = 20°

Measure of the opposite side = x

Measure of the adjacent side = 12

By applying tangent rule in the given right triangle,

tan(20°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

[tex]\text{tan}(20^0)=\frac{x}{12}[/tex]

[tex]x=12\times \text{tan}(20^0)[/tex]

Therefore, equation to get the value of 'x' will be,

[tex]x=12\times \text{tan}(20^0)[/tex]

Answer:

c = 10.81

Step-by-step explanation:

if it's a² + b² = c²

6² + 9² = c²

36 + 81 = c²

117 = c²

(square root both)

10.81 = c

(I think this is right)

Answer:

b = 120

Step-by-step explanation:

a & b are vertical angles and vertical angles are congruent, thus, a and b are congruent.

=> a = b, a = 120

=> b = 120

Answer:

Ordinal Scale

Step-by-step explanation:

The Ordinal Scale may be described as a type of measurement scale which is mostly used to convey qualitative differences while depicting level of magnitude and rank between the labels. The order of a ordinal Scale matters even though the difference between each cannot be measured. It is mostly employed to convey ideas such as level satisfaction, happiness, performance, grade and so on. For the categoroea given above :

Excellent represents the peak ; then Good, followed by Average, then, Below Average, and lastly Poor.

Answer:

The answer would be A.) 4 inches

Step-by-step explanation:

It is A. because if the base of the triangle is 10 inches and one side is 4 then the two sides of the trianlge would be the same they are congruent so if one side of the triangle is 4 then the other side of the triangle is 4.

Answer:

B. 2/3 because the probability of selecting a quarter is 1/3

Step-by-step explanation:

Find the total coins in the purse: 10 + 6 + 5 + 9 = 30. Now find out how many are not quarters: 10 are quarters, 30 - 10 = 20. The probability is 20/30, or 2/3,

Answer:

The limit of the (228.533, 234.735)

Step-by-step explanation:

The values are missing in the given question. Therefore, in order to attempt this question, we will make assumptions.

So, let's assume that:

sample size of the journal article that was reported = 5

which is applied for determining a 95% CI

Also, assuming that the resulting interval = (229.764, 233.504)

However, if we are to use a 99% CI which we deemed to be more appropriate;

Then, our objective is to find the limits of this particular interval in question.

To do that:

We need to first find the sample mean at 95% CI by using the formula:

[tex]\Big ( \bar {x} - t_{\alpha/2, df} \ \dfrac{s}{\sqrt{n}}}, \bar x + t_{\alpha/2, df} \ \dfrac{s}{\sqrt{n}}} \Big) = (229.764,233.504)[/tex]

Since; df = n - 1

df = 5 - 1

df = 4

Then;

[tex]\Big ( \bar {x} - t_{\alpha/2, 4} \ \dfrac{s}{\sqrt{n}}}, \bar x + t_{\alpha/2, 4} \ \dfrac{s}{\sqrt{n}}} \Big) = (233.504+229.764)[/tex]

[tex]2 \bar {x} = (463.268)[/tex]

[tex]\bar {x} =\dfrac{463.268}{2 }[/tex]

[tex]\bar {x} =231.634[/tex]

Sample mean = 231.634

Using the same formula to determine the standard deviation, we have:

[tex]\Big ( \bar {x} - t_{\alpha/2, df} \ \dfrac{s}{\sqrt{n}}}, \bar x + t_{\alpha/2, df} \ \dfrac{s}{\sqrt{n}}} \Big) = (229.764,233.504)[/tex]

[tex]\Big ( \bar {x} - t_{\alpha/2, 4} \ \dfrac{s}{\sqrt{n}}}, \bar x + t_{\alpha/2, 4} \ \dfrac{s}{\sqrt{n}}} \Big) = (233.504-229.764)[/tex]

[tex]\Big ( (\bar x + t_{\alpha/2, 4} \ \dfrac{s}{\sqrt{n}}} )- (\bar {x} - t_{\alpha/2, 4} \ \dfrac{s}{\sqrt{n}}}) \Big) = (233.504-229.764)[/tex]

[tex]\Big ( (\bar x + t_{0.05/2, 4} \ \dfrac{s}{\sqrt{4}}} )- (\bar {x} - t_{0.05/2, 4} \ \dfrac{s}{\sqrt{5}}}) \Big) = (233.504-229.764)[/tex]

At t = 0.025 and df = 4; = 2.776

[tex]2\times 2.776 \dfrac{s}{\sqrt{5}}= 3.74[/tex]

[tex]5.552 \dfrac{s}{\sqrt{5}}= 3.74[/tex]

[tex]\dfrac{s}{\sqrt{5}}= \dfrac{ 3.74}{5.552}[/tex]

[tex]\dfrac{s}{\sqrt{5}}= 0.6736[/tex]

[tex]s = 0.6736 \times \sqrt{5}[/tex]

s = 1.5063

The 99% CI is:

[tex]\implies \Big(\bar x \pm t_{\alpha/2,4} \dfrac{s}{\sqrt{n}} \Big)[/tex]

At t =0.005 and df =4; = 4.604

[tex]\implies \Big(231.634 \pm 4.604 \dfrac{1.5063}{\sqrt{5}} \Big)[/tex]

[tex]\implies \Big(231.634 \pm 4.604 (0.67364) \Big)[/tex]

[tex]\implies \Big(231.634 \pm 3.1014 \Big)[/tex]

[tex]\implies \Big((231.634 - 3.1014), (231.634 + 3.1014) \Big)[/tex]

[tex]\implies \Big( 228.533, 234.735 \Big)[/tex]

Answer:

The mass of 1000 atoms of gold is, in grams, of [tex]3.25 \times 10^{-19}[/tex]

Step-by-step explanation:

This question is solved by proportions, using a rule of three.

We have that:

One atom of gold has a mass, in grams, of [tex]3.25 \times 10^{-22}[/tex]. What is the mass of 1000 atoms of gold?

1000 atoms is [tex]10^3[/tex]. So

1 atom - [tex]3.25 \times 10^{-22}[/tex] grams

[tex]10^3[/tex] atoms - x

Applying cross multiplication:

[tex]x = 3.25 \times 10^{-22} \times 10^3 = 3.25 \times 10^{-22+3} = 3.25 \times 10^{-19}[/tex]

The mass of 1000 atoms of gold is, in grams, of [tex]3.25 \times 10^{-19}[/tex]

Answer: 348in^2

Step-by-step explanation:

8 x 9 = 72

72 x 2 = 144in^2 (front and back)

8 x 6 = 48

48 x 2 = 96in^2 (sides)

9 x 6 = 54

54 x 2 = 108in^2 (top and bottom)

Total Surface area = 144 + 96 + 108 = 348in^2 (second option on picture)
