Answer:

Bettina= X(let)

Darren=3x

Jonathan=6x

120=X+3x+6x

X=12

so Bettina=12 yrs

Darren=36 yrs

Jonathan=72 yrs

Answer:

Step-by-step explanation:

Let Bettina's age be B.

Then Darren's age is 3 times Bettina's, or 3B.

Jonathan's age is twice that of Darren, i.e. 2 (3B) = 6B.

Altogether, the sum of their age is

B + 3B + 6B = 120 years

10 B = 120 years

B = 12 years.

Therefore

Bettina is 12 years old

Darren is 3 times as old as Bettina, so 36 years old.

Jonathan is twice that of Darren, so 72 years old.

Total = 72+36+12= 120 years, check! :)

Step-by-step explanation:

Blaine's take-home pay is $2,500 each month, and he has created a monthly budget to become more aware of where his money goes. His budget is shown below. Blaine finds that he can join a cheaper gym for $40/month, reduce his spending money to $200, and find a phone and internet package for $175. How much will these choices save him each month?

Answers

Answer:

Amount Blaine save = $250

Step-by-step explanation:

Total take home pay = $2,500

Original budget:

Rent + electricity bills = $990

Food/groceries = $525

Gas + insurance = $320

Spending money = $235

Cellphone + Internet = $250

Gym membership = $180

Total = $2,500

New budget:

Rent + electricity bills = $990

Food/groceries = $525

Gas + insurance = $320

Spending money = $200

Cellphone + Internet = $175

Gym membership = $40

Total = $2,250

How much will these choices save him each month?

Amount Blaine save = Total take home - new budget

= $2,500 - $2,250

= $250

Amount Blaine save = $250

The sides of an oblong are in the ratio of 4:3. The oblong has a length of 12 cm and is increased by a scale factor of 2.5. What will the increased width be

Answers

Answer:

If the scale factor is increased in 2.5, the increased width will be:

22.5 cm

Step-by-step explanation:

Remember that an oblong is longer than it is wide, by this reason, the ratio of 4:3 could mean, if we give a number, by each 4 cm in the length, there is 3 cm in the width, in this form, if the oblong has a length of 12 cm, the width is:

4 cm ⇒ 3 cm12 cm ⇒ x

So:

[tex]x=\frac{12 *3}{4}[/tex][tex]x=\frac{36}{4}[/tex][tex]x=9[/tex]

Then, the original width is 9 cm, as the scale factor must be increased 2.5, we can multiply the found width to obtain the increased width:

Increased width = 9 cm * 2.5Increased width = 22.5 cm

As you can see, the increased widt will be 22.5 cm.

Brandon's time: 3 minutes 27 seconds

Step-by-step explanation:

Well, 5 feet per every second so side A would be 327.6 / 3 = 109.2

then 489 / 5 = 97.8 add them two you get 207 seconds which is 3 minutes and 45 seconds for Daniel.

For Brandon you have to find the hypotenuse of the triangle which in short is 588.6 / 3 = 196.2

Write a short para based on how the pandemic has affected travelling.

Answers

Answer:

Unlike many of history’s great tragedies, the coronavirus pandemic never stunned us with one catastrophic event. Instead, the deadly problem quietly snaked its way around the world, devastating millions as it grew into a global health crisis since it first surfaced in November.

Our realities shifted slowly at first, and before we knew it, the coronavirus took over completely.

As we closed borders, canceled events and self-quarantined at home on a mass scale, the travel industry, as well as most other sectors, began to nosedive. The collective effort to save lives meant economic catastrophe for an industry that profits from people leaving their houses.

The wound inflicted by the pandemic on the travel industry is deep, and it hasn’t stopped bleeding yet.

In a May 20 call with analysts, Royal Caribbean Cruises chief executive Richard Fain recalled how drastically travel changed after the 9/11 terrorist attacks — and how the “new normal” eventually just became normal. He expects to see a similar phenomenon in the post-coronavirus world.
