If 400,000 tourists contribute $67 million to a local economy, how much would 600,000 tourists contribute?

Answers

Answer:

[tex]100.5\ \text{million}[/tex] is contributed by 600,000 tourists.

Step-by-step explanation:

Given that,

400,000 tourists contribute $67 million to the local economy.

We need to find how much would 600,000 tourists contribute.

400,000 tourists = $67 million

1 tourist = [tex](\dfrac{67}{400,000 })\ \text{million}[/tex]

So, 600,000 tourists contribution is :

[tex]600000\ \text{tourists}=(\dfrac{67}{400,000 })\times 600000\ \text{million}\\\\=100.5\ \text{million}[/tex]

Hence, [tex]100.5\ \text{million}[/tex] is contributed by 600,000 tourists.

HELP: find the measure of the arc or angle indicated, assume that lines which appear tangent are tangent

Answers

Answer:

3) B. 65°4) D. 120°

Step-by-step explanation:

Question 3

Angle formed outside is half of the difference of intercepted arcs

m∠F = 1/2(( 360° - 115°) - 115°) = 1/2(130°) = 65°

Correct choice is B

Question 4

Angle formed by two chords is half of the sum of intercepted arcs

m∠WTU = 1/2(105° + 135°) = 1/2(240°) = 120°

Correct choice is D

On the table, x is in the left column, y is in the right.
Using the equation y = kx, we need to find k for that data
150 = k(1250)
150/1250 = k
0.12 = k

You can confirm that by doing the same with the second row, but I won’t put that here. It’s the same.

Dollars/kilowatt-hour is the label for the k of each equation (0.12, 0.15). We calculated dollars divided by (per) kWh.

Company P is less expensive than company M, because 0.12 < 0.15.

We need to buy 2,375 kWh of electricity from company P. The equation y = kx applies, where y is unknown, k = 0.12, and x = 2,375

y = (0.12)(2375)
y = $285

The total price for a computer and a
printer was $1039. If the computer
cost $750, how much did the printer
cost?

Answers

Answer:

$289

Step-by-step explanation:

If you know the cost of one of the two items, you can subtract that item from the total in order to find the price of the second item

So:   total price - computer price = printer cost

So:   $1039- $750 = $289

The printer is $289

A rectangle has a perimeter of 238 meters and a length of 67 meters what is the area of the rectangle

Answers

Answer:

3,484 meters squared

Step-by-step explanation:

Since it’s a rectangle, opposite sides are the same length. This means 2 of the sides are 67 meters each, since the length of the rectangle is 67 meters. To find the width, add the 2 sides together that we know the length of (in this case it would be 67+67) and subtract it from the total perimeter (238-[67+67]). Take the result (104) and divide it by 2 (104÷2=52). Now that we know the width is 52 meters, you can find the area by multiplying the length times the width (67*52=3,484 meters)

Remember that the perimeter is the total length around the outside of the shape, and the area is the space inside of the shape

Ethen is ‘x’ years old. Raj is 8 years older than Ethen. Find the sum of their ages in 6 years time.

Answers

Answer:

The sum of their ages in 6 years time is (2x+20) years.

Step-by-step explanation:

Given that,

Ethen is ‘x’ years old.

Raj is 8 years older than Ethen.

Raj's age = (x+8) years

We need to find the sum of their in 6 years.

After 6 years,

Ethen's age = (x+6) years

Raj's age = (x+8)+6

= (x+14) years

Sum of ages = (x+6) + (x+14)

= 2x+20

Hence, the required answer is (2x+20) years.

B) 6.5 x 4.31 = 28.015

We can infer that 1 is not in the tenths place but rather the hundredths place.

C) 8.54 x 2.3 = 19.642

We can infer that 1 is not in the tenths place.

D) 5.4 x 2.8 = 15.12

We can infer that 1 is in the tenths place.

A triangle equals 180° so set up the equation as
58+73+12x+1=180
132+12x=180 (I got 132 by adding 58,73,1)
Subtract 132 from both sides
You should get 12x=48
Divide both sides by 12
X=4
The sum of all the angles in a triangle is 180°.

(12x + 1) + 58° + 73° = 180°

12x + 132° = 180°

12x = 180° - 132°

x = 48°/12

x = 4°
