Answer:

Answer in simplified mixed form is 1 5/6

Step-by-step explanation:

We need to solve: -6 7/8 divided by (-3 3/4)

This can be written as:

-6 7/8 ÷ (-3 3/4)

Since -6 7/8 = -55/8 and -3 3/4 = - 15/4

So we can write :

-6 7/8 ÷ (-3 3/4) = -55/8 ÷ (-15/4)

or (-55/8 ) / (-15/4)

or (-55/8) * (-4/15)

or -(-220/120)

or 11/6

or 1 5/6 , this is the answer

We got the answer in simplified mixed form is 1 5/6

Julie says I added three odd numbers and my answer was 50 explain why Julie cannot be correct

ANTONII [103]

Julie cannot be right. That's because if you add three odd numbers together, <em>you always get an odd number. </em>The number 50 is an Even number.

Let's try adding 3 odd numbers together a couple of times...
3 + 3 + 3 = 9
5 + 1 + 5 = 11
7 + 3 + 5 = 15
We tried 3 examples, we could not get any even number. So, Julie's claim is wrong.

Ronin kicks a ball over the gate of the first floor balcony. The function h(t)=-36t^2+288t+9 can be used to model the height of

ale4655 [162]

Answer: 4 seconds

Step-by-step explanation:

Given: The function $h(t)=-36t^2+288t+9$ can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.

Differentiate the given function with respect to t , we get

$h'(t)=-36(2)t+288=-72t+288$

Put h'(t)=0

$\Rightarrow\ -72t+288=0\Rightarrow\ t=\dfrac{288}{72}\\\\\Rightarrow\ t=4$

Also, $h''(t)=-72$

By second derivative test, h(t) is maximum at t=4.

Hence, the time in Devon which the ball reaches it maximum height = 4 seconds

each year francesca earns a salary of 2% higher than her previous years salary. In her first 5 years at this job, she earned a t

Luda [366]

Answer:

$36,027.9

Step-by-step explanation:

Lets say her salary in the first year is s1. So, in the second year her salary will be 2% higher than x, this is, s1 + s1*0.02, so:

s2 = s1 + 0.02s1 = 1.02s1

Then in year 3 it will be s2 plus a 0.02 increase:

s3 = s2 + 0.02s2 = 1.02(s2) = 1.02 (1.02 s1) = 1.02^2(s1)

Then the same for s4: s3 salary plus the increase.

s4 = s3 + 0.02s3 = 1.02(s3) = 1.02 (1.02 s2) = 1.02(1.02*1.02 s1) =1.02^3(s1)

Finally for the 5th monts:

s5 = 1.02(s4) = 1.02^4(s1)

We know that s1+s2+s3+s4+s5 = 187,345

Lets replace all the salaries by its value depending on s1

s1 + 1.02s1 + 1.02^2(s1) + 1.02^3(s1) + 1.02^4(s1) = 187,345

We can add to the first term a s1^0 as it is eqaul to 1

s1 + 1.02s1 + 1.02^2(s1) + 1.02^3(s1) + 1.02^4(s1) = 187,345

Lets get 1s1 out as common factor:

s1 (1 + 1.02^1 + 1.02^2 + 1.02^3 + 1.02^4) = 187,345

s1 *5.20 = 187,345

Divide both sides by 5.20

s1 = 36,027.9

So, her salary in the 1st month was approximately $36,027.9

1. 5x + 2(x +6) simplify each expression

irina [24]

1. 5x+ 2(x+6)
= 5x+ 2x+ 2*6 (distributive property)
= 5x+ 2x+ 12
= (5x+ 2x)+ 12 (combine like terms)
= 7x+ 12

The correct answer is C. 7x+12~

2. <span> -3m + 3(m + 6)
= -3m+ 3m+ 3*6
= -3m+ 3m+ 18
= (-3m+ 3m)+ 18
= 18
