<span>In the question "Jamaal spent x minutes today practicing his guitar and y minutes today on homework. If the total time he spent on both is 45 minutes or more, which inequality best represents his practice time?" Since the total time he spent on both is 45 minutes or more, it means that the sum of x and y is greater than or equal to 45. Therefore, the required equation is x + y ≥ 45.</span>

Mike is biking to catch up with his sister who is already 1200 yards ahead of him. If he bikes at a speed of 600 yards per minut
sashaice [31]

Answer:

8 minutes.

Step-by-step explanation:

Let m represent number of minutes.

We have been given that Mike is biking to catch up with his sister who is already 1200 yards ahead of him. His sister is biking at a speed of 450 yards per minute.

So total distance covered by Mike's sister after m minutes would be 450m+1200.

Mike bikes at a speed of 600 yards per minute, so total distance covered by Mike in minutes would be 600m.

Now, we will equate both expressions to find minutes at which both distances will be equal as:

600x=450m+1200  

600x-450m=450m-450m+1200

150m=1200

\frac{150m}{150}=\frac{1200}{150}

m=8

Therefore, it will take after 8 minutes for Mike to catch his sister.

#<br> 6x²-12x-25=-7<br> vertex<br> axis of symmetry
tino4ka555 [31]
Axis of symmetry: x=1
Vertex: (1, -24)

Explanation:

6x²-12x-25=-7

6x²-12x-18=0

a=6, b=-12, c=-18

Formula of axis of symmetry: x=-b/2a

x=-b/2a

x= -(-12)/2(6)

x= 12/12

x= 1

Vertex: (1,?)

Sub x= 1 into the equation,
6(1)² - 12(1) - 18 = y

6 - 12 - 18 = y

y = -24

In order to have 6,000,000 in 40 years with a 5.75% rate. how much should be deposited each month?
PSYCHO15rus [73]

Answer:

Step-by-step explanation:

This is an Annuity question. It is asking for recurring monthly payment(PMT).  <em>You can use a financial calculator to solve it. I am using (Texas Instruments BA II plus)</em>

Since the payments occur monthly , adjust the interest rate to monthly rate and multiply  40 years by 12 since we have 12 months in a  year<em>.</em>

Total duration of investment ; N = 40*12 = 480

Interest rate; I/Y = 5.75% /12 = 0.4792%

Future value; FV = 6,000,000

Present value ; PV = 0

then CPT PMT = 3,222.912

Therefore $3,222.91  should be deposited each month to achieve the goal.

Lets Do

\\ \sf\longmapsto p = 2(l + w) \\ \\ \sf\longmapsto l + w =  \frac{p}{2}  \\ \\ \sf\longmapsto w =  \frac{p}{2}  - l \\ \\ \sf\longmapsto  \boxed{ \bf \: w =  \frac{p - 2l}{2} }
