Answer:

82

Step-by-step explanation:

Let the unknown number be x

If an unknown number is added to 8, this is expressed as;

8 + x

<em>If The sum is  then divided by 9 to give the answer 10, then;</em>

<em>(8+x)/9 = 10</em>

<em>Cross multiply</em>

<em>8 + x = 9 * 10</em>

<em>8 + x = 90</em>

<em>x = 90 - 8</em>

<em>x = 82</em>

Hence the unknown number is 82

The corporate team building event will cost $12 if it has three attendees if there are five attendees how much was a quaker team
Norma-Jean [14]

Answer:

Cost to arrange the event for 5 attendees will be $20.

Since cost to arrange corporate team building event for 3 attendees is = $12

Cost to arrange the event for 1 attendee will be = \frac{12}{3} = $4

You borrowed 43,800 at a SIMPLE interest rate of 4.8%. If you pay it back in 2 years, how much
Naddik [55]

Answer:

I = $4204.8

Step-by-step explanation:

Given that,

Principal, P = $43,800

Interest rate = 4.8%

Rate = 2 years

We need to find the interest that is paid back. We know that, simple interest is given by :

I=\dfrac{PRT}{100}

Put all the values,

I=\dfrac{43800\times 4.8\times 2}{100}\\\\=\$4204.8

So, the required interest is equal to $4204.8 .

5/8 + 11/12 in fraction simplified in simplest form
Katarina [22]
You need to get the lowest common denominator first, this would be 24 (8 x 3 and 12 x 2)
So multiple he top and bottom to get the denominator to 24
For 5/8: 5 x 3 = 15 and 8 x 3 = 24
For 11/12: 11 x 2 = 22 and 12 x 2 - 24
so you have 15/24 and 22/24 
Then you add the numerators together 15 + 22 = 37, to become 37/24 and because 37 is prime 37/24 is simplest terms

Will give Brainliest. Write a linear equation for this statement:
Llana [10]

Answer:

H(d) = -9.5(d-1) + 100

Step-by-step explanation:

Let d_n denote the number of hits on day n, then:

d_1 = 100, d_3 = 81

we can calculate that over the 2 days, the number of hits decreased by 19.

Assuming this is a linear equation and not an exponential decay line, then the series equation would be: d_n_+_1 = d_n - 9.5

To write this as a linear equation, if H(d) is a function where d is the day starting from 1 and H(d) is the nubmer of hits on that day:

H(d) = -9.5(d-1) + 100
