The answer to the given mathematical expression is [tex]\(\frac{20}{3}\)[/tex].

To solve this expression, we need to follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This is often abbreviated as PEMDAS.

First, we simplify the expression inside the parentheses:

[tex]\(27 - 22 - 3 \times 5 + 25\)[/tex]

Multiplication comes before addition and subtraction, so we perform the multiplication first:

[tex]\(27 - 22 - 15 + 25\)[/tex]

Next, we perform the subtraction and addition from left to right:

[tex]\(5 - 15 + 25\)[/tex]

[tex]\(-10 + 25\)[/tex]

[tex]\(15\)[/tex]

Now we have simplified the denominator, so the expression becomes:

[tex]\(\frac{100}{15}\)[/tex]

Finally, we divide 100 by 15 to get the result:

[tex]\(\frac{100}{15} = \frac{20 \times 5}{3 \times 5}\)[/tex]

We can cancel out the common factor of 5:

[tex]\(\frac{20}{3}\)[/tex]

Juan will put fencing around the outside of the enclosure. How much fencing does he need for the enclosure?

Answers

If Juan intends to put fencing around the enclosure, that means that we are looking at the perimeter of the image (the outside). We can count the amount of lines between the dots to determine how much fencing he will need. After counting the perimeter of this figure, we see that the total is 22. We do not know what the units are, so for now we can just say that he will need 22 units of fencing to fully enclose this shape.

If the power required to lift a weight of 10 N in 3 seconds is 60 W, what is the distance the weight moves? A. 1m B. 6m C.18m D.36m

Answers

we know that

Power = [work done]/[time taken]
work done=power*time taken
power---------- > 60 W
time taken------ > 3 sec
then
work done=60*3=180 J

and we know
work done=Force*distance
distance=[work done]/[force]
work done=180 J
force=10 N
distance=180/10=18 m

 the answer is the option C.18m

Rewrite 0.434343... as a fraction

Answers

Final answer:

The repeating decimal 0.434343... can be rewritten as a fraction by defining the decimal as a variable, manipulating the equation, and finally isolating the variable to find that the fraction form of 0.434343... is 43/99.

Explanation:

To rewrite the repeating decimal 0.434343... as a fraction, we first define the repeating decimal as a variable, let's call it x = 0.434343.... Then, to isolate the repeating section, we multiply x by 100, given the two-digit repeat, which gives us 100x = 43.434343.... By subtracting the original equation from this new one, we get: 99x = 43, because 100x - x = 43.434343... - 0.434343... simplifies to 99x = 43. Dividing both sides by 99 gives us x = 43/99, which is the fraction form of the repeating decimal.

To rewrite the repeating decimal 0.434343... as a fraction, we first denote it as x. Next, we can subtract the non-repeating part from the repeating part to get a new number, y. Then, we can express x and y as fractions and solve for the repeating fraction part.

Your best choice is 11.55.

What happens when you multiply any number by 10

Answers

Notice that in order to move the decimal place, we had to add a zero to the end of the number. This will happen every time you multiply by 10, 100, or 1,000. You will need to add the same amount of zeroes to the end of the number to match thenumber of places you moved the decimal.
You multiply. But in the particular case of the number 10 you would take said number and add a zero to it, as you take on zero from 10 and it becomes one. Any number times one it equal to itself. Add the zero back on and boom! Answer.

a box of crackers has a volume of 48 cubic inches. what is the volume of a similar box that is smaller by a scale factor of 2/3

Answers

For this case what you need to know is that the original volume of the cookie box is:
 V = (w) * (l) * (h)
 Where,
 w: width
 l: long
 h: height.
 We have then:
 V = (w) * (l) * (h) = 48 in ^ 3
 The volume of a similar box is:
 V = (w * (2/3)) * (l * (2/3)) * (h * (2/3))
 We rewrite:
 V = ((w) * (l) * (h)) * ((2/3) * (2/3) * (2/3))
 V = (w) * (l) * (h) * ((2/3) ^ 3)
 V = 48 * ((2/3) ^ 3)
 V = 14.22222222 in ^ 3
 Answer:
 the volume of a similar box that is smaller by a scale factor of 2/3 is:
 V = 14.22222222 in ^ 3

How deep is a well that takes eight cranks on the six- inch diameter windlass to raise the bucket?

Answers

In order to answer this, you would need to find the circumference of the windlass. This would represent the distance of one rotation. When you know the distance of one rotation, you would then multiply it by eight for all eight Kranks. This is knowing each crank is a complete turn. Here is the formula C= pi times the diameter. So, 3.14 x 7 is 18.84 inches for 1 crank. 18.84 inches times 8 equals 150.72 inches. This is an approximation because pi is an approximation.

Answer:  The surface area of the given cylinder is:  " 747. 32  in² " .

______________________________________________________
Explanation:
______________________________________________________
The formula for the "Surface Area, "S. A." , of a cylinder : 

" S.A. = 2 [tex] \pi [/tex] r² + 2[tex] * \pi [/tex] * r * h " ;

in which:   [tex] \pi [/tex] = 3.14 (we shall use this approximation) ; 

                           S.A. = surface area (in "square units" ;
                                                            in our case, "square inches" ;

                                r = radius = 7 in. 

                                h = height = 10 in. 
__________________________________________________
   Let us plug in our "known" — and/or "given" — values ; into the formula & solve for the "S.A." (surface area of this "cylinder") :
__________________________________________________

 →  S.A. = 2 [tex] \pi [/tex] r² + 2 * [tex] \pi [/tex] * r * h ; 


→  S.A.  =  2 (3.14) * (7 in.)²   +    2 * (3.14) * (7 in) * (10 in)  ; 

→  S.A.  = [ 2 * (3.14) * (7²)  * (in²) ] +  ( 2 * 3.14 * 70 *  in²) ;

              = ( 2 * 3.14 * 49 * in² ) + (439 .6 * in²) ;

a gardener can plant 17 seeds in 25 minutes at that rate how long will it take him to plants 51 seeds

Answers

51 / 17 = 3
3 * 25 = 75

Answer: It will take the gardener 75 minutes to plant 51 seeds.

Hope this helps!

If the gardener plants 51 seeds, then the time taken will be 75 minutes.

What are ratio and proportion?

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

A gardener can plant 17 seeds in 25 minutes at that rate.

We know that the ratio of time and number of seed plantations will remain the same.

Let T be the time and S be the number of seed plantations.

T / S = 25 / 17

If the gardener plants 51 seeds, then the time taken will be

T / 51 = 25 / 17

T = 1275 / 17

T = 75 minutes

If the gardener plants 51 seeds, then the time taken will be 75 minutes.

Let E be the point of intersection of the diagonals of a parallelogram. The lengths of the line segments from E to two of the parallelogram’s vertices are 3 meters and 4 meters. What are the lengths of the segments from E to the other two vertices of the parallelogram? Justify your answer.

Answers

The length is going to be 3m and 4m.
The diagonals of a parallelogram has the following property:

They bisect each other. Which means each diagonal divides the other diagonal in two equal halves.

So, the point of intersection of two diagonals is the midpoint of both diagonals. If the distance from that point of intersection E, to the vertices of parallelogram is 3 meters and 4 meters, the distance from E to opposite vertices will also be the same i.e. 3 meters and 4 meters respectively, because the diagonals bisect each other.

Answers

Okay 2
Really

During

Square
67
First, if ordered pairs are in the form of (x,y) then the first one means plug in x with 0. If you do that, you get y= -10(0)+18. Simplify to get y=18. So, for the first one, it is (0,18). For the next one, you plug in 1 for x. So, y=-10(1)+18. Simplify to get y=-10+18. Simplify again to get y=8. So the second one is (1,8). For the last one you have only the y value, so plug in 78 for y. So, 78=-10x+18. We want to isolate x, so subtract 18 from both sides. You get 60=-10x. Now divide by -10 to get -6=x. So, the last ordered pair is (-6,78)

please awnser i fraction form 4 3/4 times 3 3/5 times 15

Answers

Simplify the following:
(4 + 3/4) (3 + 3/5)×15

Put 3 + 3/5 over the common denominator 5. 3 + 3/5 = (5×3)/5 + 3/5:
(4 + 3/4) (5×3)/5 + 3/5 15

5×3 = 15:
(4 + 3/4) (15/5 + 3/5)×15

15/5 + 3/5 = (15 + 3)/5:
(4 + 3/4) (15 + 3)/5×15

15 + 3 = 18:
(4 + 3/4)×18/5×15

Put 4 + 3/4 over the common denominator 4. 4 + 3/4 = (4×4)/4 + 3/4:
(18×15)/5 (4×4)/4 + 3/4

4×4 = 16:
((16/4 + 3/4)×18×15)/5

16/4 + 3/4 = (16 + 3)/4:
(18×15)/5 (16 + 3)/4

16 + 3 = 19:
19/4×18/5×15

19/4×18/5×15 = (19×18×15)/(4×5):
(19×18×15)/(4×5)

15/5 = (5×3)/5 = 3:
(19×18×3)/4
The gcd of 18 and 4 is 2, so (19×18×3)/4 = (19 (2×9) 3)/(2×2) = 2/2×(19×9×3)/2 = (19×9×3)/2:
(19×9×3)/2

19×9 = 171:

(171×3)/2

171×3 = 513:

Answer: 513/2

The result of 4 3/4 times 3 3/5 times 15 is 513/2.

To multiply the fractions 4 3/4, 3 3/5, and 15, we first need to convert the mixed numbers to improper fractions.

4 3/4 can be written as (4 * 4 + 3)/4 = 19/4

3 3/5 can be written as (3 * 5 + 3)/5 = 18/5

Now we multiply the fractions:

(19/4) * (18/5) * 15 = (19 * 18 * 15)/(4 * 5) = 5130/20

To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 10:

5130/20 = (5130 ÷ 10)/(20 ÷ 10) = 513/2

Therefore, the result of the multiplication in fraction form is 513/2.
