Answer:

10.26secs

Step-by-step explanation:

Let's start by converting 3minutes 15seconds to second

How

60secs=1min

Xsec=3mins

Let's cross multiply

x=60×3

X=180secs

180+15

195secs

So 19 copies=195 secs

1copy=x sec

Cross multiply

19x=1×195

19x=195

Divide both sides by 19

X=10.26secs

Step-by-step explanation:

It is eqivilent to 37.5

I think you meant to say "equivalent" instead of "equipment"

To find equivalent fractions to 3/8, you would multiply top and bottom by the same number.

If we multiply the top and bottom by 5 for instance, then

3*5 = 15

8*5 = 40

So 3/8 is equivalent to 15/40

--------------

Another example: multiply top and bottom by 9

3*9 = 27

8*9 = 72

This means 3/8 is equivalent to 27/72

-------------

Now let's say you were asked if 15/40 was equivalent to 3/8

To check this, you would assume they are equal, then cross multiply like so

15/40 = 3/8

15*8 = 40*3 ... cross multiply

120 = 120

Since we end up with the same thing on both sides, we have confirmed that 15/40 = 3/8 is a true equation.

Work Shown:

a = 3 and b = 4 are the two legs

c = x is the unknown hypotenuse

Use the pythagorean theorem to solve for c

a^2 + b^2 = c^2

3^2 + 4^2 = c^2

9 + 16 = c^2

25 = c^2

c^2 = 25

c = sqrt(25)

c = 5

This question involves using the Pythagorean theorem to find the length of the hypotenuse of a right triangle. Given the lengths of the sides as 3 and 4, we find that the hypotenuse (denoted as 'x') is 5.

The subject of this question is mathematics and it is related to finding the length of the hypotenuse of a right triangle using the Pythagorean theorem. In the case of this problem, the two sides of the triangle are given (3 and 4) and the hypotenuse (x) is what we are solving for.

The Pythagorean theorem is as follows: a² + b² = c². In this notation, a and b are the lengths of the two sides, and c is the length of the hypotenuse. Given that a is 3 and b is 4, to find out x (or c in the formula), we square each of those values (3² + 4²) and get 9 + 16, respectively. This means x² = 25, so the value of x (the hypotenuse) is √25, which equals 5.

Answer:

35°, 55°

Step-by-step explanation:

sin(3x + 2)° = cos(x+44)°

Since sine and cosine are based upon right triangles, the two angles must add up to 90°. Thereby, 3x+2 +  x+44 = 90. Combine like terms to get:

4x + 46  =  90       subtract 46 from both sides

    -46     -46

4x          = 44        divide both sides by 4

Line 2  Associative, Additive inverse within brackets only and distributive.

Line 3 Associative

Line 4 is the Associative answer to 1

Step-by-step explanation:

Whilst we divide negative numbers as an inverse multiplication.

Where 4.5 x a negative 4 of the sum -1 would decrease by 2 decimals to 0.04 and so would the 5, they become additive inverse.

They can only be distributive if there are 2 multipliers.

Explanation of correlation coefficient, its significance in determining relationship strength between variables, and how to interpret its value.

The correlation coefficient provides a measure of how strongly two variables are related in a linear manner. It ranges from -1 to 1, where 1 represents a perfect positive correlation, -1 a perfect negative correlation, and 0 no correlation.

A correlation coefficient close to 1 or -1 indicates a strong relationship, while a coefficient close to 0 indicates a weak or no relationship. This numerical value helps determine how predictable changes in one variable are as the other variable changes.

Interpreting the correlation coefficient assists in understanding the strength and direction of the relationship between variables, aiding in making predictions or drawing conclusions based on the data's patterns.

Final Answer:

The surface area of the triangular prism is 156 cm².
Option C (156 cm²) is the correct answer.

Explanation:

To find the surface area of a triangular prism, you need to calculate the areas of all the faces and sum them up. The surface area will include the areas of:
- The two triangular bases, and
- The three rectangular sides.

Since the sides of the triangular bases are 3 cm, 4 cm, and 5 cm, and it is mentioned that they form a right triangle, we can consider those lengths to be the sides of a right-angled triangle where 3 cm and 4 cm are the perpendicular sides, and 5 cm is the hypotenuse. The length (height) of the prism is 12 cm.

1. Calculate the area of one triangular base:
  The area of a right-angled triangle can be calculated using the formula:
  Area = (Base * Height) / 2
 
  In our case, the base and height correspond to the two sides that are perpendicular to each other, which are 3 cm and 4 cm, respectively:
  Area_triangle = (3 cm * 4 cm) / 2
  Area_triangle = 12 cm² / 2
  Area_triangle = 6 cm²

  Since there are two identical triangular bases, we double the area:
  Total_area_triangles = 2 * Area_triangle
  Total_area_triangles = 2 * 6 cm²
  Total_area_triangles = 12 cm²

2. Calculate the area of the three rectangular sides:
  Each rectangle side is formed by the length of the prism and one of the sides of the triangle. There are three sides, so we have three rectangles:
  Rectangle 1 (Side a): Area = side_a * length = 3 cm * 12 cm = 36 cm²
  Rectangle 2 (Side b): Area = side_b * length = 4 cm * 12 cm = 48 cm²
  Rectangle 3 (Side c): Area = side_c * length = 5 cm * 12 cm = 60 cm²

  Now sum the areas of the rectangles:
  Total_area_rectangles = Rectangle 1 + Rectangle 2 + Rectangle 3
  Total_area_rectangles = 36 cm² + 48 cm² + 60 cm²
  Total_area_rectangles = 144 cm²

3. Sum up the areas of the triangular bases and rectangles to get the total surface area:
  Total_surface_area = Total_area_triangles + Total_area_rectangles
  Total_surface_area = 12 cm² + 144 cm²
  Total_surface_area = 156 cm²

Therefore, the surface area of the triangular prism is 156 cm².
Option C (156 cm²) is the correct answer.

Answer:

18.1 cm

Step-by-step explanation:

Consider a segment parallel to CD and passing through B.

This segment will form a right-angle triangle with A

It's length would be equal to the length of CD (the missing length)

Height of that triangle:

11 - 4 = 7

CD² = 16² - 7²

CD² = 207

CD = sqrt(207)

AC² = AD² + CD²

AC² = 11² + 207

AC² = 328

AC = 2sqrt(82)

Which is roughly 18.1 cm

Answer:

D

Step-by-step explanation:

We know that an arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is always constant.

−5, −7, −10, −14, −19, …

Here difference between -5 and -7 is -2

But difference between -10 and -7 is -3

⇒ Difference is not constant.

Therefore, this sequence does not represents an arithmetic sequence.

1.5, −1.5, 1.5, −1.5, …  

Here difference between 1.5 and -1.5 is 3

But difference between -1.5 and 1.5 is 3

⇒ Difference is not constant.

Therefore, this sequence does not represents an arithmetic sequence.

4.1, 5.1, 6.2, 7.2, …  

Here difference between 4.1 and 5.1 is 1

But difference between 6.2 and 5.1 is 1.1

⇒ Difference is not constant.

Therefore, this sequence does not represents an arithmetic sequence.

−1.5, −1, −0.5, 0, …

Here difference between -1.5 and -1 is 0.5

But difference between -1 and -0.5 is 0.5

⇒ Difference is constant.

Therefore, this sequence represents an arithmetic sequence.

Answer:

A) Mark speed = 7mph  Annie speed is 1.2miles faster at 8.2mph

B) Mark had sailed ratio to Annie 17.5: 20.5

= 3mph faster in 15 minutes This makes it 12mph faster every 5 hrs

The percentage speed of Mark is 83% of 100% of Annie.

This makes Annie 7% faster

7% of 7mph = 1.2 so it has to be 1.2miles faster and not 12mph faster to meet at 15minutes.

Step-by-step explanation:

Annie is 12mph faster they pass 15mins after departure

= 0-15= Annie is 4mp faster than Mark at 15mins.

Annie = 5 miles = m+60m = 60 this makes mark 5.6 : 6 ratio per 15 minutes 28:30 = 1.4 : 1.5 ratio at 15 minutes.

Mark = 5 miles = 5 x 1.4 =7mph + 0m = 7mph

Annie = 5 miles = 5 x 1.5 = 7.5mph + 7 = 8.2mph

A=We can check that 1/4 of 8.2mph distance = 2.5 per 15mins

M=We can check that 1/4 of 7.0mph distance = 1.75 per 15mins

A=We can check that 2.05 per 15mins = 2.5 x 4  = 8.2 mph = 41miles in 5 hr

M=We cna check that 1.75 per 15mins = 1.7 x 4 x 5= 7mph = 35 miles every 5hr

Step-by-step explanation:

Given a decay rate of 2.5% per year for a radioactive element, the half-life of this element, calculated using first-order kinetics, would be approximately 27.7 years.

The question seeks to find the half-life of a radioactive element given a decay rate of 2.5% per year. To solve this, we need to utilize the concept of first-order kinetics which is used to model radioactive decay.

First, we express the decay rate as a decimal, thus 2.5% is 0.025. To find the half-life or T1/2, we can make use of the formula T1/2 = ln(2) / k, where k is the decay constant or rate.

By inserting the values into this formula, it would be T1/2 = ln(2) / 0.025 which gives us approximately 27.7 years (rounded to one decimal place) as the half-life of the given radioactive element.

https://brainly.com/question/31591373

#SPJ11

The half-life is 27.7 years.

Half-life is the time required for half of the radioactive atoms to decay in a sample. In this case, the decay rate k = 2.5% is equivalent to 0.025 in decimal form.

By using the formula t1/2 = ln(2) / k, we can calculate the half-life.

Plugging in k = 0.025,

t1/2 = ln(2) / 0.025

= 27.7 years.

Therefore, the half-life of the element is approximately 27.7 years.
