In a basketball game, Kyrie scored 5 less than twice as many as Steph. Combined the two scored 55 points. How many points did Ky

Aleonysh [2.5K]

Let steph score be x
Then kyrie score is 2x-5
Sum of the two scores is 55
Therefore x+2x-5=55
3x-5=55
3x=60
x=20

Therefore steph score is 20
And kyrie score is 2(20)-5
40-5=35

you deposited $5500 in a account that pays 3.6% annual interest. find the balance after 2 years if the interest is compound mont

Sedaia [141]

Answer:

$5,909.97

Step-by-step explanation:

We will use the compound interest formula for this problem as shown below:

$A=P(1+\frac{r}{n} )^{nt}$

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, change 3.6% into a decimal:

3.6% -> $\frac{3.6}{100}$ -> 0.036

Now plug in the values:

$A=5,500(1+\frac{0.036}{12})^{12(2)}$

$A=5,909.97$

After 2 years, the balance would be $5,909.97

There are 178 7th grade students and 20 chaperones going on the field trup to the equarium.each bus holds 42 people how many bus

zaharov [31]

Answer:

The group will need to take a minimum of 5 buses to carry all the people to the trip

Step-by-step explanation:

Given:

Number of 7th grade students going on the trip = 178

Number of chaperones going on the trip = 20

Number of people each bus can hole = 42

To find the number of buses the group will have to take.

Solution:

Let minimum number of buses the group will have to take = $x$

using unitary method:

If 1 bus can hold = 42 people

Then, $x$ buses can hold = $42x$ people

Total number of people for the trip = $178+20=198$

The total number of people that can go in $x$ buses must be greater than or equal to 198 in order to carry all the people to the trip.

Thus we have the inequality:

$42x\geq198$

Solving for $x$

Dividing both sides by 42.

$\frac{42x}{42}\geq\frac{198}{42}$

$x\geq4.71\approx 5$ [As number of buses must be in whole number]

Thus, the group will need to take a minimum of 5 buses to carry all the people to the trip.
