Answer:

25.38

Step-by-step explanation:

Its a 3-D block, so you have to find the distance from on corner to the opposite corner of the roof, but first find the distance from corner to corner on the floor.

20^2+12^2=c^2

400+144=544=c^2

c=[tex]\sqrt{544}[/tex]

then find corner of floor to opposite roof corner.

100+544=644=c^2

c=[tex]\sqrt{644}[/tex]

so its about 25.38 feet

Answer:

25.4 ft  

Step-by-step explanation:

Let D1 be the distance from one corner to the diagonally opposite one and D2 be the  diagonal distance from one corner to the ceiling.

D1² = 20² + 12²

D2² = D1² + 10²            Substitute the value of D1²

D2² = 20² + 12² + 10²

D2² = 400 + 144 + 100

D2² = 644

D2 = √(644)

D2 = 2√(161)

D2 ≈ 25.4 ft

The next number in the sequence 16, 4, 20, 24, 44 is 68 and in the sequence 6, 5, 15, 10, 70 is 61.

A sequence's series is the total number of terms in the sequence.

A series follows some pattern for example if you take data set of natural numbers then there will be a sequence of that data and something will be due to that we can form that series.

Now the given series are,

16, 4, 20, 24, 44

and 6, 5, 15, 10, 70

Now the difference between the two terms of the series 16, 4, 20, 24, 44

4 - 16 = 12 = 4*3

20 - 4 = 16 = 4*4

24- 20 = 4 = 4*1

44 - 24 = 20 = 4*5

So let x be the next term; hence it can be written as

x - 44 = 4*6

x = 24 + 44

x = 68

Now for the series 6, 5, 15, 10, 70, it is an alternative series,

6 - 1 = 5

5 x 3 = 15

15 - 5 = 10

10 x 7 = 70

So the next term is given as,

70 - 9 = 61

Hence, The next number in the sequence 16, 4, 20, 24, 44 is 68 and in the sequence 6, 5, 15, 10, 70 is 61.

Answer: 9

Step-by-step explanation: This is the answer because you would subtract so the equation would be 24-15=9. Hope this helps!

The pair of polygons in the image are not similar. Although they are both rectangles, they do not have the same corresponding side ratios.

A rectangle is defined by having four right angles and two pairs of parallel sides. The corresponding sides of similar rectangles are in proportion. In the image, the rectangle on the left has side lengths of 11 ft and 10 ft, while the rectangle on the right has side lengths of 9.4 ft and 8.4 ft.

The ratio of the corresponding sides is not the same for both pairs of sides. The ratio of the left side lengths is 11 ft / 9.4 ft, which is about 1.17. The ratio of the right side lengths is 10 ft / 8.4 ft, which is about 1.19. Because the corresponding side ratios are not the same, the rectangles are not similar.

Answer:

50 lbs

Step-by-step explanation:

Jack picked 100 lbs of cranberries. If fresh cranberries have 99% of water, then in 100 lbs of cranberries there are 99 lbs of water and 1 lb of "cranberries".

After being dried this 1 lb of "cranberries" form 2% and the rest 98% is the water. Let the weight of the dried cranberries be x lbs, then

x lbs - 100 %,

1 lb - 2 %.

Therefore,

[tex]\dfrac{x}{1}=\dfrac{100}{2},\\ \\x=\dfrac{1\cdot 100}{2}=50\ lbs.[/tex]

The cranberries, starting at 100 lbs with 99% water content, will reduce to 50 lbs after drying, at which point they have 98% water content. The substance weight shouldn't change being 1 lb as only the water content has changed.

The subject of your question falls under the category of Mathematics, specifically in Percentage and Weight Change. Given that fresh cranberries have 99% water and you started with 100 lbs, then only 1% of this weight, or 1 lb, is non-water content. This is the weight of cranberries' substance that doesn't change during drying.

The partially dried cranberries are 98% water. So the question is 'What weight would give us 1 lb as 2% (100%-98%=2%) of this weight?' The answer is 1 lb divided by 2% (or 1lb/0.02) which gives us 50 lbs. So, the cranberries will weigh 50 lbs after drying.

Answer:

Number 95 is bigger than number 85.

Step-by-step explanation:

If we want to find which number is the bigger one; we subtract the numbers in  two orders:

95 - 85 = 10

and

85 - 95 = -10

Since the first order (95 - 85) gives a positive answer;

Then it implies that number 95 is bigger than number 85.

Since the second order (85 - 95) gives a negative answer;

Then it implies that number 85 is smaller than number 95.

The inequalities 12x + 4 > 16 and 3x - 5 < -14 simplify to x > 1 and x < -3 respectively. In graphical form, both inequalities represent lines extending from the points x = 1 and x = -3, with x > 1 going towards the right and x < -3 moving leftward.

To solve this inequality problem, we first isolate the variable on one side of the inequality for both expressions. Let's begin with 12x + 4 > 16. We can start by subtracting 4 from both sides to get 12x > 12, then divide each side by 12, resulting in x > 1.

Solve 12x + 4 > 16:

Subtract 4 from both sides to isolate 12x:

12x > 16 - 4

12x > 12

Divide both sides by 12:

x > 1

Solve 3x - 5 < -14:

Add 5 to both sides to isolate 3x:

3x < -14 + 5

3x < -9

Divide both sides by 3:

x < -3

Now, you have two separate solutions:

For the first inequality, x > 1.

For the second inequality, x < -3.

This means the solution graph includes all values of x that are greater than 1 or less than -3. In graphical terms, it's the union of two intervals:

Solution Graph: (-∞, -3) ∪ (1, ∞)

This represents all real numbers less than -3 and all real numbers greater than 1.

Answer:

Price after discount = 2.4 (1-.3)

Price after discount = 2.4 (.7)

Step-by-step explanation:

We know the cost after the discount.

Price after discount = original price - original price * discount rate

Factoring out the original price

Price after discount = original price (1- discount rate)

We know the discount rate = .3 and the original price is 2.4

Price after discount = 2.4 (1-.3)

Price after discount = 2.4 (.7)

Price after discount = 1.68

Answer: The three sides are 14, 14, 20

===================================

x = length of the two equal sides

x+6 = length of the third longer side

add up the three lengths x, x, x+6. Set it equal to the perimeter 48. Solve for x

x+x+x+6 = 48

3x+6 = 48

3x+6-6 = 48-6 ... subtract 6 from both sides

3x = 42

3x/3 = 42/3 ... divide both sides by 3

x = 14

If x = 14, then x+6 = 14+6 = 20

The three sides are 14, 14, 20

We can check this by adding up the three sides 14+14+20 = 28+20 = 48 and we get the right perimeter.

Answer: #5 is 10 student tickets and 20 adult tickets

Step-by-step explanation:

Answer:

20 adult tickets sold and 15 student tickets sold

Step-by-step explanation:

Answer:

The function is an exponential,

f(x) = A exp(log(3)x) = 2×3^x = 2(3)^x

The first point you graph for any exponential is (0,A), here (0,2). After (1,6), the next point might be (2,18).

Step-by-step explanation:

(0,2×3^0) = (0,2)

(1,2×3^1) = (1,6)

(2,2×3^2) = (2,2×9) = (2,18)

2(3)^x ought to be written 2×3^x, that is, two times three raised to the x power. x can be any real number.

Since 3 = exp(log(3)), we can substitute for 3 and write 2×exp(log(3))^x. Since exp(p)^q = exp(p×q), the function is also written 2×exp(log(3)x).

exp(x) is also written e^x. exp(x) is the unique function with exp(0)=1, and with the slope of the tangent line at exp(x) equal to exp(x). For instance, the slope at exp(0) is 1, the slope at exp(1) = e is e, slope at exp(2) is exp(2).

for A exp(b x), the slope at x is A b exp(b x).

For 3^x = exp(log(3)x), we have

3^0=1, slope log(3)

3^1=3, slope 3log(3),

3^2=9, slope 9log(3).

Step-by-step explanation: Put 2 as the exponent to get 3x3=9, then do 9x2=18. So x = 2 is y = 18 = (2,18).
