dalia saved $3,000 last year.she saved $600 in the month of January.what percent of the total amount of money she save last year did dalia save in the month of January

Answers

The percent of the total amount of money she save last year did Dalia save in the month of January is 20%

What is percentage?

A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction to change the percentage to a fraction,  put the percentage number in the numerator and 100 in the denominator.

Given that, Dalia saved $3,000 last year. She saved $600 in the month of January.

The percentage of the total amount of money she save = 600/3000x100

= 60/3

= 20

Hence, the asked percentage is 20%

Dalia saved 20%of her entire years savings in January. 

3000 is her entire savings

300 is 10 percent of her entire savings, 300+300=600

so 10%+10%=20%

A northbound bus and a southbound bus are at a bus stop at the same time. The northbound bus returns to the bus stop every 20 minutes and the southbound bus returns to the bus stop every 25 minutes. How long will it be before both busses are at the bus stop at the same time again?

Answers

Answer: It will be after 100 minutes both buses stop at the same time again.

Step-by-step explanation:

Since we have given that

Number of minutes after which the northbound bus stops = 20 minutes

Number of minutes after which the southbound bus stops = 25 minutes

We need to find the number of minutes it will before both buses are at the bus stop at the same time again.

So, L.C.M. of 20 and 25 = 100

Hence, it will be after 100 minutes both buses stop at the same time again.

Answers

Answer:

B, E

Step-by-step explanation:

Given the first function:

y=-2x+(2)/(3)

A Linear System with no solutions is graphically represented by two parallel lines, therefore with the same slope. So in this case, m has to be equal to -2.

And to this inconsistent system, if the linear parameter is not so relevant. So if m=-2 then b may be either equal to -1/3 or -2/3 according to the options.

Given the alternatives

No Solution System:

\left\{\begin{matrix}y=-2x+(2)/(3) & \n y=-2x-(1)/(3) & \end{matrix}\right.

Or

\left\{\begin{matrix}y=-2x+(2)/(3) & \n y=-2x-(2)/(3) & \end{matrix}\right.

Answer:

m = -2 and b = -1/3

m = -2 and b = -2/3.

Step-by-step explanation:

y = -2x - 1/3

y = -2x - 2/3

This system has no solutions because y cannot be 2 different values at once.

4²+5[61-(5×6)] what's the answer for this

Answers

In this question we can see that there are different type of brackets used. Also there is multiplication addition and subtraction. So we need to follow the BODMAS rule.
B = Bracket
O = Of
D = Division
M = Multiplication
A = Addition
S = Subtraction
Now let us focus on the problem in hand.
4^2 + 5[ 61 - (5 * 6)] = (4)^2 + 5[ 61 - (30)]
                                 = (4)^2 + 5[ 61 - 30]
                                 = 16 + 5 [31]
                                 = 16 + 155
                                 = 171
So the answer for the question comes out to be 171. I hope the procedure is clear enough for you to understand. You can always use this method for solving similar problems in future.
If you would like to solve 4^2 + 5 * [61 - (5 * 6)], you can calculate this using the following steps:

4^2 + 5 * [61 - (5 * 6)] = 16 + 5 * [61 - 30] = 16 + 5 * 31 = 16 + 155 = 171

The correct result would be 171.
