A large tree casts a shadow of 42 m. At the same time, a 4 m high fence, standing vertically, casts a shadow of 7 m. Find h, the height of
the tree.

Answer:

x = 6, AM = 22

Step-by-step explanation:

Since A is the midpoint of RM, then RA = AM = 3x + 4 , then

RM = RA + AM , substitute values

7x + 2 = 3x + 4 + 3x + 4 = 6x + 8 ( subtract 6x from both sides )

x + 2 = 8 ( subtract 2 from both sides )

x = 6

Thus

AM = 3x + 4 = 3(6) + 4 = 18 + 4 = 22

Answer:

option B is correct-$1.45+$0.55× ≤ $35.

Step-by-step explanation:

Total cost equals the $1.45, plus $0.55 per mile. She can only spend $35 or less

In math language:

35≤1.45+.55x

33.55≤.55x

61≤x

So, Ariel can go 61 miles or less for $35

Hope u like it ♥️

The inequality is  $1.45 + $0.55x ≤ $35

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size

Given:

Total cost equals the $1.45, plus $0.55 per mile.

She can only spend $35 or less

$1.45 + $0.55x ≤ $35

0.55x≤ $35-1.45

0.55x≤33.55

x≤ 61

Hence, Ariel can go 61 miles or less for $35.

Answer: (7, 9)

Step-by-step explanation: To solve this system, I would use addition.

To solve a system of equations by addition,

we need one of our variables to cancel out.

Notice that we have a 4x in our first equation.

If we had a -4x in our second equation, the x's would cancel.

To create a -4x in the second equation,

we must multiply the entire equation by -4.

So we have (-4)(x + 6y) = (61)(-4).

Rewriting this equation, we have -4x - 24y = -244.

Now let's rewrite both equations.

Now when we add the equations together, the x's cancel.

So we're left with -29y = -261.

Now divide both sides by -29 and we have y = 9.

To find x, we plug a y back in for x in either equation.

So let's go with our second equation, x + 6y = 61.

Plugging a 9 in for y, we have x + 6(9) = 61 or x + 54 = 61.

Subtracting 54 from both sides, we have x = 7.

So x = 7 and y = 9 which we can write as the ordered pair (7, 9).

Answer:

5/4 times 1/3

Step-by-step explanation:

I got my answer because it said she has 1 1/4 hours to do her 3 chores and there is a mixed number in the problem so convert that mixed number to an improper and you get 5/4. Now the 3 is a whole number so we have to change that to an improper as well and that would be 3/1. Next we have to find the reciprocal of 3/1 and that would be 1/3 then you add a multiplication sign to the problem and it should look like this.

5/4 x 1/3

Ans:- [tex]\red{\bold{\boxed{156 \degree}}}[/tex]

Answer:

156°

Step-by-step explanation:

The sum of the interior angles of a regular polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 15, thus

sum = 180° × 13 = 2340°

Divide the sum by the number of sides for each interior angle, that is

interior angle = 2340° ÷ 15 = 156°

area of the rectangle= base (28) by height (35)

Answer:

588 in²

Step-by-step explanation:

length: 28 inches

height: a

hypotenuse: 35 inches

Pythagorean Theorem: a² + b² = c²

a² + 28² = 35²

a² + 784 = 1225

a² = 441

a = [tex]\sqrt{441}[/tex]

a = 21 inches

Area of rectangle: Length x Width

Step-by-step explanation:

The perimeter is 22 meters and is twice the sum of its length and width. 8+3 is 11, and 11 times 2 is 22. Also, its length is 2 meters more than twice its width. Width is 3 because 3 times 2 is 6, and 6 plus 2 more meters is 8 (which is the length). Hope this helps!

Answer:

x = -4

Step-by-step explanation:

Add like terms:

6 + 6x + 6x = -42

12x + 6 = -42

Subtract 6 from both sides:

12x = -48

Divide each side by 12:

x = -4

Answer:

6+6x+6x = - 42

6+12x = -42          (combine like terms)

12x = -42-6

12x = -48

x = -48/12

x = -4
