A man was traveling by air is allowed a maximum of 20kg luggages .The man has four bags weighing 3.5kg ,15 kg ,2kg and 1.5kg .Fi

KatRina [158]

Answer:

See explanation

Step-by-step explanation:

Maximum weight = 20 kg

Bag 1 = 3.5kg

Bag 2 = 15 kg

Bag 3 = 2kg

Bag 4 = 1.5kg

Total weight of bags = 22 kg

Excess weight of his luggage = Total weight of bags - Maximum weight

= 22 kg - 20 kg

= 2 kg

Express the excess weight as a percentage of his maximum weight allowed = excess weight / maximum weight × 100

= 2/20 × 100

= 0.1 × 100

= 10%

Express the excess weight as a percentage of his maximum weight allowed = 10%

Helppp!!! Simplify this. Please explain it too. 18x^4 – 3x^3 – 2x^3 + x^2 – 10 + 6

strojnjashka [21]

Answer: 18x^4 - 5x^3 + x^2 - 4

Step-by-step explanation:

We need to add like terms.

-10 and 6 are like terms

-10 + 6 = - 4

-3x^3 and -2^3 are like terms

-3x^3 + -2^3 = -5x^3

There are no other like terms.

18x^4 - 5x^3 + x^2 - 4

During a baseball season, team a scores 9 runs for every 7 runs that team b scores. The total number of runs scored by both team

mrs_skeptik [129]

Answer:

∴ Team b scores is 630

And team a scores is 810

Step-by-step explanation:

Given;

Team a scores $9$ runs for every $7$ runs that team b scores.

Lets,

Think b is scores $x$ runs;

Then a is scores $x+(2\times\frac{x}{7} )$ ;

Because every 7 runs of b , a is scores more 2 runs.

Total number of runs scored by both teams is 1440

Runs score by team a + Runs score by team b=1440

$x+(2\times\frac{x}{7} )+ x =1440$

$2\times x+ \frac{2\times x}{7}=1440$

$\frac{(14\times x)+(2\times x)}{7} =1440$

$\frac{16\times x}{7} =1440$

$16\times x=1440\times 7$

$x=\frac{10080}{16}$

$x=630$

∴ Team b scores is 630

And team a scores is $630+(2\times \frac{630}{7} )=810$
