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

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:

Y=-1

Step-by-step explanation:

Y-4-4Y=-1

-3Y=-1+4

-3Y=3

Y=3÷-3

Y=-1

Answer:

y = -1

Step-by-step explanation:

y - 4 - 4y = - 1   Combine like terms

y - 4y - 4 = - 1

-3y - 4 = - 1 Add 4 to each side

-3y - 4 + 4 = -1 + 4

-3y = 3 Divide each side by -3

-3y/-3 = 3/-3

y = -1

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

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:

Total amount Ari would have saved after 6 months is $220

Step-by-step explanation:

Ari received $100 as a birthday gift and has decided to save this money as well as add $20 of his own money each month. The total money Ari has saved can be estimated using the equation y = 20x + 100, where x is the number of months and y is the total amount of money saved. How much money will Ari have saved after 6 months?

Solution

Given:

g(x) = 20x + 100

where,

x = number of months

g(x) = the total amount of money saved

How much money will Ari have saved after 6 months?

g(x) = 20x + 100

When x = 6

g(x) = 20(6) + 100

= 120 + 100

= 220

g(x) = $220

Total amount Ari would have saved after 6 months is $220

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!

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:

193.

Step-by-step explanation:

We would solve this question by cross multiplication.

If a sound of fertilizer covers 45 square feet of lawn and the lawn is 8666.7 square feet

To get fertilizer quantity we have

1 pound = 45 square

Unknown = 8666.7 square feet

8666.7/45

= 192.59 when approximated we get 193.

Therefore she has to buy 193 pounds of fertilizer

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.

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°
