Explanation:

There are 3 right triangles here. They are all similar triangles allowing us to form the proportion

7/h = h/56

which solves to...

7/h = h/56

7*56 = h*h

392 = h^2

h^2 = 392

h = sqrt(392)

h = sqrt(196*2)

h = sqrt(196)*sqrt(2)

h = 14*sqrt(2)

Note: h is the geometric mean of 7 and 56.

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

Use the pythagorean theorem to solve for 'a'. Focus on the smaller triangle on the left

7^2 + h^2 = a^2

7^2 + (sqrt(392))^2 = a^2

49 + 392 = a^2

441 = a^2

a^2 = 441

a = sqrt(441)

a = 21

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

Then we can find b. Again use the pythagorean theorem. Focus on the largest right triangle this time.

a^2 + b^2 = (7+56)^2

21^2 + b^2 = 63^2

441 + b^2 = 3969

b^2 = 3969 - 441

b^2 = 3528

b = sqrt(3528)

b = sqrt(1764*2)

b = sqrt(1764)*sqrt(2)

b = 42*sqrt(2)

Answer:

295.936

Step-by-step explanation:

First find out what 544^2 is.  That is 295,936.  There are 100 ml in 1 liter.  So divide 295,936 by 100 to see how many liters are in 295,936 ml.  

295,936÷100=295.936

Answer:

The value of a mathematical expression is the result of the computation described by this expression when the variables and constants in it are assigned values. The value of a function, given the value(s) assigned to its argument(s), is the value assumed by the function for these argument values.

Step-by-step explanation:

Yes, the value of an expression does mean the answer.

The value of an expression is a variable that is assigned to a number.

Lets say we have 3n + 2 = 10.

"n" is the variable and we need to find the value of it.

In that kind of question, that is the answer for an expression.

But there are cases where we have the value and we need to solve with it. Then, the value would not be the answer.

Best of Luck!

Answer:

The length of the rectangle is 15 cm.

Step-by-step explanation:

breadth(b)=?

length(l)= 3+2b

perimeter(P)= 42 cm

Now,

  P = 2 ( l+b )

or, 42= 2 ( 3+2b+b)

or, 42 = 2 ( 3+3b)

or, [tex]\frac{42}{2}[/tex] = 3+3b

or, 21 = 3+3b

or, 21-3 =3b

or, 18 = 3b

or, [tex]\frac{18}{3}[/tex] = b

or, 6 = b

Here, Breadth(b)= 6 cm

Length (l) = 3 + 2*6

              = 3 + 12

              =15 cm

Hey there!

72 athletes can eat for 6 days.

1 athlete can eat for 6(72), or 432 days.

54 athletes can eat for 432/54, or 8 days.

They can eat for 2 more days.

Let me know if this helps :)

Answer:

8 days

Step-by-step explanation:

sufficient food for 72 athlete to last 6 days

when 18 athletes are absent : 72-18=54

multiply scouts by days , to see how many food is packed :

72*6=432

then divide the amount of food packed by the number of scout attended:

432/54= 8 days

Answer:

L= 16 m

W= 12 m

Step-by-step explanation:

let us define the parameters of the parallelogram

let the length be L

and the width be W

given that the W= L-4

perimeter= 72 meters

We know that the perimeter of a parallelogram is given as

[tex]P=2L + 2W[/tex]

Substituting W= L-4 for W we have

[tex]72=2L + 2(L-4)\\\\72= 2L+2L-8 \\\\72= 4L-8\\\\4L= 72-8\\\\4L= 64[/tex]

Divide both sides by 4 we have

[tex]L= 64/4\\\\L= 16 m[/tex]

From w= L-4 we can find w by setting L= 16

W= 16-4

W= 12 m

Answer:

x = -8

Step-by-step explanation:

To answer this equation solve for x. When doing so make sure to get x one side

First subtract 4x from each side. This means the equation is now

x + 6 = -2

Next subtract 6 on both side and you should find x

x = -8

Answer:

x > -7

Step-by-step explanation:

Step 1: Translate

Twice a number = 2x

Six more = + 6

At least = >

-8 = -8

Step 2: Write out inequality

2x + 6 > -8

Step 3: Solve

2x > - 14

x > -7

Answer: b. False

Step-by-step explanation:

The term " correlation" defines the nature of the relationship between the two quantities.

The term "causation" defines the effect of one variable one the other.

They both are used to analyse the relationship between variables such that

Presence of causation implies there is correlation between variables but correlation does not imply causation.

So, correlation coefficient (r) has nothing to do with the cause.

That means having a good correlation of r = 0.71 between the time spent playing video games each week and grade point average for a group of high school boys doesn't imply that playing video games causes students to get lower grades.

Hence, the given statement is False.

Answer:

∠ EFH = 112°

Step-by-step explanation:

∠ ACD and ∠ EFH are Alternate exterior angles and are congruent, thus

11x - 20 = 9x + 4 ( subtract 9x from both sides )

2x - 20 = 4 ( add 20 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12

Thus

∠ EFH = 11x - 20 = 11(12) - 20 = 132 - 20 = 112°

x = y -8 hope this helps?

Answer:

243 cm^3

Step-by-step explanation:

The faces of a cube are squares.

A = s^2

s^2 = 9 cm^2

s = 3 cm

The side of the square is the edge of the cube and is 3 cm.

V = s^3

V = (3 cm)^3 = (3 cm)(3 cm)(3 cm) = 27 cm^3

The volume of one cube is 27 cm^3.

The volume of 9 cubes is 9 * 27 cm^3 = 243 cm^3

Answer: 243 cm^3

Answer:

[tex]t \: = ( \frac{2a - 7}{3} )[/tex]

Step-by-step explanation:

Answer:

The approximate length of one side of the canvas (approximate to the nearest hundredth inch)= 10.63

Step-by-step explanation:

There are two ways to solve this problem . One is the use of the calculator and the other is the use of the fraction.

Now the square has equal sides length = breadth .

So we can simply find the length on one side by taking square root with the help of the calculator .

So when you press the symbol of square root after entering the number 113 we get the answer 10.63

Square = Length * breadth

Square = Length * length

Square = L²

One side =√ L²= L so √113= 10.63

The approximate length of one side of the canvas (approximate to the nearest hundredth inch)= 10.63

Answers:

25 = 5*5 which is the same as 25 = 5^2

100 = 2*2*5*5 which is the same as 100 = 2^2*5^2

16 = 2*2*2*2 which is the same as 16 = 2^4

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

Explanation:

To find the prime factorization of 25, we divide by prime numbers. We see that 25/2 = 12.5 isn't a whole number, and neither is 25/3 = 8.33 (approx). But 25/5 = 5 is a whole number. The result is a prime number so we can stop here. This shows that 25 = 5*5 = 5^2

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

We'll do the same for 100 as well. Start with dividing over 2

100/2 = 50

50/2 = 25

we can't do 25/2 as mentioned earlier, but we can say 25/5 = 5

So basically 100 = 2*2*25 = 2*2*5*5 = 2^2*5^2

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

The same will happen with 16 as well. We divide by 2 until we arrive at a prime number result

16/2 = 8

8/2 = 4

4/2 = 2

We have three 2's as denominators and that last result 2 is included in the set of prime factors as well to say 16 = 2*2*2*2 = 2^4

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

The factor tree for each is shown below. For something like 100, there are a few ways to draw out the tree. The same applies for 16 as well.

Add n to each side

8n+n + 9 = -n+n +5

Answer:

The total amount Alex spent is $ 9

Step-by-step explanation:

The given parameters are;

The amount Alex spends on food = 2/3 of his paycheck

The amount Alex spends on coffee = $3

Therefore, we have;

Fraction of the paycheck spent on coffee = 1 - 2/3 = 1/3 of p

The  amount Alex spends on coffee = 1/3 of his paycheck

Therefore, we have;

1/3 × p = $3

p = 3 × $3 = $9

The total amount Alex spent = $ 9

The amount Alex spends on food = 2/3 × $9 = $6.
