The scale on a map says that 6cm represents 8km What is the actual number of kilometers that is represented by 8cm

Answers

Answer 1

If a map has a scale where 6 cm represents 8 km, using proportion, the actual distance in km that 8 cm represents is: 10.7 km.

Given the following:

Scale of map: 6 cm represents 8 km

Required:

Actual distance that 8 cm on the map represents.

We would apply our knowledge of proportion to solve this problem as follows:

Let x represent the actual distance we are looking.

Thus, the following proportion can be made:

6 cm = 8 km

8 cm = x km

Cross multiply

[tex]x = \frac{8 \times 8}{6} \\\\x = 10.7 $ km[/tex]

Therefore, if a map has a scale where 6 cm represents 8 km, using proportion, the actual distance in km that 8 cm represents is: 10.7 km.

please help asap!!!!!!​

Answers

Answer:

56

Step-by-step explanation:

1. We can use the exterior angle theorem to find the value of y. The exterior angle theorem states that the exterior angle of a triangle is equal to the sum of the two remote sides. This means that (y - 25) + (y + 12) = y + 43

2. (Solving)

Step 1: Simplify both sides of the equation.

[tex]y + 43 = y - 25 + y + 12[/tex] [tex]y + 43 = (y+y)+(-25+12)[/tex] [tex]y + 43 = 2y -13[/tex]

Step 2: Subtract 2y from both sides.

[tex]y + 43 - 2y = 2y - 13 - 2y[/tex] [tex]-y + 43 = 13[/tex]

Step 3: Subtract 43 from both sides.

[tex]-y + 43 - 43 = 13 - 43[/tex] [tex]-y = -56[/tex]

Step 4: Divide both sides by -1.

[tex]\frac{-y}{-1} = \frac{-56}{-1}[/tex] [tex]y = 56[/tex]

Step 5: Check if solution is correct.

[tex](56) + 43 = (56) - 25 + (56) + 12[/tex] [tex]109 = 31 + 56 + 12[/tex] [tex]99 = 87 +12[/tex] [tex]99 = 99[/tex]

Therefore, y = 56.

You have 7 times as many nickels
as pennies. You have 16 nickels
and pennies altogether. How
much money do you have in all?

Answers

The total money you have is $40.14.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

There are 7 times as many nickels as pennies

Let there are n nickles and p pennies.

⇒ p = 7n

Now, there are  16 nickels and pennies altogether

⇒ p + n = 16

Put p = 7n we get,

⇒ 7n + n = 16

⇒ 8n = 16

⇒ n = 16/8

⇒ n = 2

Therefore,  p = 7*2

⇒ p = 14

Thus there 14 pennies and 2 nickels.

Now, since 1 penny = 0.01 dollars

and 1 nickel = 20 dollars

⇒ 14 pennies = 14*0.01 dollars = 0.14 dollar

and, 2 nickel = 2*20 dollars = 40 dollars

So, Total money = $40 + $0.14

Total money = $40.14

Thus, the total money you have is $40.14.

The Slope-Intercept form of the equation of a line is: y=mx + b

where m=slope (often called 'rise over run')

b = y-intercept (the point on the y-axis when x=0)

Suppose the value of x varies from x = a to x = b . There are at least two ways of thinking about what percent x changed by. We'll explore two of them here. For each of the following questions, write an expression in terms of a and b to answer the question. Method 1 b is how many times as large as a ? times as large Therefore, b is what percent of a ? % Hence, if x varies from x = a to x = b , x changes by what percent?

Answers

The change in the value of x, as a percentage, is given by:

[tex]\frac{b - a}{a} \times 100\%[/tex]

The percentage change is given by the change multiplied by 100% and divided by the initial value.

In this question, x varies from [tex]x = a[/tex] to [tex]x = b[/tex], which means that the initial value is a, and the change is b - a. Then, the percentage chance in the value of x is given by:

What is cos(338)? Solve by hand, no calculator.
Correct answer gets BRAINLIEST.

Answers

9514 1404 393

Answer:

  0.927184

Step-by-step explanation:

Assuming you want cos(338°), it is equal to cos(22°). This value is an irrational root of a 26th-degree polynomial. (Neither the polynomial, nor the root are easy to find by hand.)

The values of trig functions for 30° and 45° are well-known, as are half-angle and angle sum/difference formulas. The nearest angle for which cosine is relatively easy to find is 22.5°. A 2nd-order Maclaurin series expansion of the cosine function about that angle gives the approximation ...

  cos(x) ≈ cos(π/8)(1 -π²/128) +π/8·sin(π/8) +(π/8·cos(π/8) -sin(π/8))x -1/2·cos(π/8)x²

For your angle of 22°, the value of x needed in this expression is 11π/90. The values of cos(π/8) and sin(π/8) are the irrational numbers ...

  cos(π/8) = √(2 +√2)/2 ≈ 0.92387953

  sin(π/8) = √(2 -√2)/2 ≈ 0.38268343

If you use the approximation pi ≈ 355/113, both for the above formula and for the angle of interest, this reduces to the sum ...

  cos(22°) ≈ 71√(2-√2)/16272 +132383951√(2+√2)/264777984

This would be tedious to calculate by hand, but is not impossible. The value this sum produces will be correct when rounded to 7 decimal digits.

Before calculators, trig function values were found in published tables. These days, tables are available on-line. Previously, they were published in books, usually along with information that helped with interpolation between table values, when necessary.

Before calculators, mathematicians spent lifetimes calculating accurate trig tables. For all but a very few angles, the cosine function of rational degree values will be an irrational number, as it is for cos(22°).

Answers

The scalar triple product is 0.

If v = 4i - j and w = 6i + 7j - 4k, then their cross product is

v × w = (4i - j) × (6i + 7j - 4k)

v × w = 24 (i × i) + 28 (i × j) - 16 (i × k) - 6 (j × i) - 7 (j × j) + 4 (j × k)

v × w = 28k - 16 (-j) - 6 (-k) + 4i

v × w = 4i + 16j + 34k

and

u • (v × w) = (i + 4j - 2k) • (4i + 16j + 34k)

u • (v × w) = 4 + 64 - 68

u • (v × w) = 0

Yes, they are coplanar.

The vectors v and w together span a plane. v × w is a vector that is perpendicular to this plane. Since the dot product of u with this vector is 0, this means u is perpendicular to v × w, which in turn means that u is in the same plane as v and w.

I = $141.60; P = $590; t = 6 years
Find the rate

Answers

To find the rate, you need to have the equation for r.

Using the simple interest formula:

I = P • r • t

Divide both sides by P•t to isolate r:

I / P • t = (P • r • t)/ P • t

I / P • t = r

Now that we have the formula for r, substitute the given values into the equation:

r = $141.60/($590 • 6)
r = 0.04 or 4%

Therefore, the interest rate is 4%
