Troy is going to Spain and needs to convert his dollars to euros. He knows that when he goes, $5.00 is equivalent to about 3.45 Euros, How many will he get for $125?

Answers

Answer 1

125/5=25
25*3.45=86.25

86.25 euros

Answer 2

To solve this, you need to set up a proportion.

$5/3.45 euros = $125/x euros

then, cross multiply

5x=(3.45)(125)
5x=431.25
x=86.25

The answer is 86.25 euros

Given: LM ∥ KN , KL ∥ NM LP = h1 = 5 cm, MQ = h2 = 6 cm PKLMN = 42 cm Find: Area of KLMN

Answers

Answer:

Area = 630/11 cm² = 57 3/11 cm²

Step-by-step explanation:

Area = (5 cm)(KN) = (6 cm)(KL)

Perimeter = 2(KN +KL) = 42 cm

So, ...

KN = 1.2·KL . . . . divide the area equation by 5 cm

1.2·KL +KL = 21 cm . . . . . divide the perimeter equation by 2

KL = (21 cm)/2.2 . . . . . . . divide by the coefficient of KL

Substituting for KL in the area equation, we have ...

Area = (6 cm)(21 cm)/2.2 = 630/11 cm²

find the values of x and y in the following equation. (x + yi) + (4 + 9) = 9 -4i

Answers

we have that

if the expression is (x + yi) + (4 + 9) = 9 -4i
x+13=9-----------> x=9-13-------------> x=-4
yi=-4i----------- > y=-4

the solution is
x=-4
y=-4

if the expression has a typing error and it is really (x + yi) + (4 + 9i) = 9 -4i
then
x+4=9------------> x=9-4-------< x=5
y+9=-4-------------> y=-4-9 ------------> y=-13
the solution is
x=5
y=-13

Final answer:

In this question we solve the given complex number equation. By comparing real and complex components on both sides of the equation, we find the values satisfying the equation are x = 5 and y=-13.

Explanation:

In this complex number equation, we must solve for x and y: (x + yi) + (4 + 9) = 9 -4i. Begin by simplifying the left side of the equation, to give (x + 4 + yi +9i) = 9 - 4i. This further simplifies to (x + 4) + (y + 9)i = 9 -4i.

Now we can see that the real component of the equation (x + 4) must equal the real component on the other side of the equation (9), and the complex component of the equation (y + 9)i must equal the complex component -4i. Setting these equal gives x + 4 = 9 and y + 9 = -4.

Solving these gives x = 5 and y = -13, which are the values for x and y satisfying the equation.

solve 3y − 7 = y + 5 and explain each step please so i understand

Answers

3y − 7 = y + 5

So first, make sure you have a variable on one side only. Just subtract y from both sides.

2y - 7 = 5

Now, isolate the variable by adding 7 on both sides (inverse operations) to cancel the negative 7.

2y = 12

Finally, divide by the coefficient of the variable, in this case, 2.

y = 6

That's your answer (y = 6)! Hope this helped!

What you must do for this case is the clearance of the unknown y.
We have then:
Step 1:
(3y - 7) - y = (y + 5) - y

What is a cylindrical shape?

A cylinder is a three-dimensional solid object with two bases that are identically circular and are connected by a curving surface that is located at a specific height from the center.

Examples of cylinders are toilet paper rolls and cold beverage cans.

The volume of a cylinder is πr²h.

Curved surface area = 2πrh.

Total surface area = 2πr(h + r).

Given, The cylinder has a radius of 13mm and a height of 16mm.

Therefore, The volume of this cylinder is,

= π×(13)²×16 mm³.

= 8,490.56 mm³.

How do you check your answer for volume of a cylinder? Desperate need of answering

Answers

1. Make sure you're using the correct formula for the dimensions given. The usual formula gives volume in terms of radius and height. If you are given the diameter, the formula will be different, or you need to compute the radius before you use the formula.

2. Make sure you're using the appropriate value for π. Many calculators have the value built-in. Many problems posted on Brainly require the use of 3.14, which will give different answers. (One recent problem required the use of 3.) If your calculator doesn't have π built in, a reasonable value is 355/113, which is good to 7 significant figures.

3. Make sure the units you are using are compatible (generally, all the same). If your height is in one unit (say inches) and your diameter is in another unit (say centimeters), you need to do units conversion before you put the numbers in the formula. The result of putting your units in the formula with your numbers should be that you end up with units cubed. For example, for a radius of 2 cm and a height of 3 cm, the volume will be
.. V = π(2cm)^2*(3 cm) = 12π cm^3.

4. Compare the dimensions and the volume to things you know. You know the approximate size of a gallon jug, a 2 liter pop bottle, a 5-gallon bucket. Check your answer for reasonableness.

5. Make an estimate based on the dimensions. Round to 1 or 2 significant figures and make a guess as to the approximate result you should get. For this, you can use 3 for π, as you just want to be "somewhere in the ballpark" as opposed to being off by a factor of 10 or more. This requires a certain amount of number sense and knowledge of multiplication tables.

6. Make certain your calculator is being used correctly. If parentheses are involved, make sure you enter the closing parentheses--as opposed to letting the calculator put them in according to its own rules. If division or fractions are involved, make sure you have parentheses around the denominator in every case. 1/2*3 ≠ 1/(2*3) It can be helpful to use a calculator that shows you what it did. (The Google calculator does that, for example.)

7. Sometimes, it helps just to do the calculation twice (possibly in a different order). Inadvertent error can creep in even when you think you're paying attention.

8. If you're doing the math by hand, make use of all available techniques for checking your arithmetic.

Brandon sights a helicopter above a building that is 200 feet away at an angle of elevation of 30 degrees. To the nearest foot, How high above the ground the is the helicopter

Answers

The problem says that Brandon sights a helicopter above a building that is 200 feet away at an angle of elevation of 30 degrees. So, you can calculate the height asked, by following this procedure:

Tan(α)=Opposite leg/Adjacent leg

α=30°
Opposite leg=x
Adjacent leg=200 feet

When you substitute these values into the formula above (Tan(α)=Opposite leg/Adjacent leg), you have:

Tan(α)=Opposite leg/Adjacent leg
Tan(30°)=x/200

You must clear "x":

x=200xTan(30°)

Therefore, the value of "x" is:

x=115 feet

How high above the ground the is the helicopter?

The answer is: 115 feet

A gardener wants to run a border around the outside of her garden. She plots it on a grid to plan how much she will need. The garden is in the shape of a rectangle with vertices at (3, 9) (5, 9) (3, 3) (5, 3). Find the total length of border needed. 8ft 12ft 16ft 24ft

Answers

1. To solve this exercise you must plot the vertices of the rectangle: (3,9);(5,9); (3,3); (5,3). The graph is shown in the figure attached.

2. As you can see in the graph, the rectangle has 6 feet long (L=6 feet) and 2 feet wide (W=2 feet).

3. Then, the perimeter of the rectangle is:

P=2L+2W

4. When you substitute the values of "L" and "W" into P=2L+2W, you obtain:

P=2(6 feet)+2(2 feet)
P=12 feet+4 feet
P=16 feet

Therefore, the total length of border needed is 16 feet.

Final answer:

The perimeter of a rectangle with the vertices given by the student is found by adding twice the length and twice the width, resulting in a total border length needed of 16 feet.

Explanation:

The student is asking about calculating the perimeter of a rectangular garden using the coordinates of its vertices. To find the total length of border needed, we look at the coordinates (3, 9), (5, 9), (3, 3), and (5, 3) given for the rectangle. The distance between two points on the same vertical line, like (3, 9) and (3, 3), is the absolute difference of the y-coordinates, which is,

9 - 3 = 6 feet.

Similarly, the distance between two points on the same horizontal line, like (3, 9) and (5, 9), is the absolute difference of the x-coordinates, which is

5 - 3 = 2 feet.

Since a rectangle has two pairs of equal sides, the total perimeter is 2 times the length plus 2 times the width. Therefore, the total length of border needed is,

2 x 2 feet + 2 x 6 feet

= 4 feet + 12 feet

= 16 feet.
