Answer:

a = 6.7m is the answer.

Step-by-step explanation:

a = ?

b = 6m

c = 9m

According to the Pythagorean theorem,

a² + b² = c²

a² + 6² = 9²

a² + 36 = 81

a² = 81 - 36

a² = 45

a = 6.708

round to the nearest tenth,

a = 6.7m

∴ Janice is 6.7m high up in the air.

A person can pay $6 for a membership to the history museum and the go to the museum for just $2 per visit. What is the maximum n

nirvana33 [79]

Answer:The maximum number of visits a member of the history museum can make for a total cost of $40 is 17

Step-by-step explanation:

Let x represent the number if visits that visits the person makes to the museum.

Let y represent the cost of x visits

A person can pay $6 for a membership to the history museum and then go to the museum for just $2 per visit. It means that the total cost, y for x visits will be

y = 2x + 6

For a total cost of $40, y = 40. So

40 = 2x + 6

2x = 40 - 6

2x = 34

x = 34/2 = 17

Connie collected 50 seashells during her 5-day vacation. Each day she collected 3 more than the previous day. How many seashells

vfiekz [6]

Answer:

The number of seashells collected on day 1 to day 5 is 4, 7, 10, 13 and 16 respectively

Step-by-step explanation:

This is a question that deals with consecutive numbers.

Let x represent the number of seashells collected on her first day.

Given that she collected 3 more each day, then

On day 2, she collected x + 3

On day 3, she collected x + 6

On day 4, she collected x + 9

On day 5, she collected x + 12

Adding up the above will give the number of sea shells collected on day 1;

i.e.

x + x + 3 + x + 6 + x + 9 + x + 12 = 50

Collect like terms

x + x + x + x + x + 3 + 6 + 9 + 12 = 50

5x + 30 = 50

5x = 50 - 30

5x = 20

Multiply ⅕ to both sides

⅕ * 5x = ⅕ * 20

x = 4.

This mean that she found 4 seashells on day 1;

Recall that day 2 = x + 3

So, day 2 = 4 + 3 = 7 seashells

day 3 = x + 6

day 3 = 4 + 6 = 10 seashells

day 4 = x + 9

day 4 = 4 + 9 = 13 seashells

day 5 = x + 12

day 5 = 4 + 13 = 16 seashells

Hence, the number of seashells collected on day 1 to day 5 is 4, 7, 10, 13 and 16 respectively

A rule of thumb is that for a 3 credits college course a student should study at least 6 hrs. per week. If your MAT course is a

scZoUnD [109]

The number of hours that should be used to study over the weekend = $\frac{11}{15}$ hrs

The number of hours to study 3 credit course is = 6hrs/ week.

The number of hours studied on monday, wednesday and friday,

= 3/5 + 16/4 +2/3

The lowest common multiple of the denominators 5, 4 and 3 = 60

= $\frac{36 + 240 + 40}{60}$

= 316/60

Reduce to the lowest figure by dividing through with 4,

= 79/15

To detemine the extra hours to be studied over the weekend, subtract 79/15 from 6.

that is, 6/1 - 79/15

The lowest common multiple of denominators 1 and 15 = 15

= $\frac{90 - 79}{15}$

= $\frac{11}{15}$ hrs
