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.

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.

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°

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

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

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

Let me know if you have any questions.

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°
