Here is an expression 3.2 evaluate the expression when t is 4 middle school math

Answers

Answer 1

Answer: Answer: C. 3.2 × 10^4

Step-by-step explanation: for this case the multiplication of the values with exponent are summed, as the exponent are the 6 and -3

6 - 3 = 3

this will be the exponent of the common value which is the 10.

after you only need to multiply 8 and 4 by separate the

8 * 4 = 32.

then we only need to place the values one by one

32 × 10^3

3 is the result of the sum of the exponent.

10 is the common value.

32 is the result of the product.

if we add another zero to the multiplication we get 3.2 and exponent finish with one more zero, then we get this result

3.2 × 10^4

because of that the C is the correct answer, keep in mind that the other answers do not apply correctly the rule of the exponent, because the rest of answer give us wrong answer with final result of the exponent.

Answer:

Step-by-step explanation:

1.)

3x=3

x=1

2+y=0

y=-2

solution: (1,-2)

2.)

6y = -36

y = -6

-4x+12 = -12

-4x=-24

x = 6

solution: (6,-6)

Answer:

Top: x=1, y= -2

Bottom: x= 6, y= -6

Step-by-step explanation:

Top:

Isolate x for y: 2(3+y) + y = 0  

Simplify: 6+3y=0

Isolate y for 6+3y=0: y = -2

For x= 3 + y: x = 1

Bottom:

Isolate x for : -4x - 2y= -12:     x= [tex]\frac{-6 + y}{2}[/tex]

Simplify: 6y+ 12 = -24

Isolate y for 6y+ 12 = -24: y = -6

For x= [tex]-\frac{-6 -6 }{2} = 6[/tex] : x = 6

Help asap pls. The mean of a math test took by 50 students is 85% Two students got a 10% on the test. If those outliers were removed, what would the new mean be? Pls don't answer for points. And also DONT ANSWER TO ASK A QUESTION COMMENT IT. it takes away a chance for people who actually know the answer to answer

Answers

Answer:

okay I'm not 100% sure but I have a good idea (it's okay if u remove me it's just an educated guess)

89%

Step-by-step explanation:

if there were 100 students that would mean 1 student represented 1% of the results. so if there were 50 students 1 student would represent 2% of the results. so if two students were removed then that would mean the result would improve by a total of 4% which would get you 89%

Answers

Answer:

1: Tip, $2.23

2: Tax, $0.74

3: Total, $17.87

4: Split, $5.95

Step-by-step explanation:

To find the tip, you must multiply the tip percentage by the bill, (which has not been taxed yet). The tip is 15%, which is equivalent to 0.15. The tip multiplied by the bill (0.15×14.90) equals $2.23.

To find the tax, you do the same as you did with the tip. The tax is 5%, which equals 0.05. The tax multiplied by the bill, (0.05×14.90) equals $0.74. The total cost is the bill, tip, and tax added together, (14.90+2.23+0.74) equals $17.87. To find out how much each person will pay equally, you must divide the total bill by the amount of people, (17.87÷3) which equals $5.95.

Answer:

We can see from the table that 1 km is exactly half way between 2 and 3 laps. So it will take 2.5 laps to run 1 km.

Since it takes Angel 2 minutes to run 1 lap, she will take

2.5 laps1 km⋅2 minutes1 lap=5 minutes1 km.

So it takes Angel 5 minutes to run 1 km.

Since it takes Jayden 5 minutes to runs 3 laps, she runs 1 lap in 53 minutes. Thus, it takes Jayden

2.5 laps1 km⋅5 minutes3 laps=52⋅53 minutes/km=256 minutes/km=416 minutes/km.

So it takes Jayden 416 minutes to run 1 km.

i actually dont know what the answer-answer is but i think this will help alot.

Answer:

Step-by-step explanation:

Distance traveled in 2 minutes by Angel = 2/5 kilo meter

Distance traveled in 1 minute by Angel = [tex]\frac{2}{5}[/tex] ÷ 2

                                                                 [tex]=\frac{2}{5}*\frac{1}{2}[/tex]

                                                                 = 1/5 kilometer

Brian received 45 trading cards from his mother and 25 trading cards from his uncle to start a collection.
Each week, Brian uses his allowance to buy a new pack of 15 trading cards to add to his collection.

Write an equation in slope-intercept form to represent the situation. Use x for the independent variable and y for the dependent variable. Identify what both variables represent.

Answers

Answer:

The representation of Brian's situation in slope intercept form is:

                              y= 15x +70

Step-by-step explanation:

Let x be the number of weeks Brian started his collection.

y be the number of cards Brian has at present.

                         y= 45+25+ 15 x

                   or, y= 15 x +70

which is in the form of,

                              y= mx +c                (slope intercept form)

where,

m= slope

x= x- intercept

Charlotte recorded the number of minutes she spent exercising in the past ten days: 9, 13, 5, 2, 9, 1, 14, 3, 5, 7. Find the median of the data.

Answers

Answer:

The median is 7.

Step-by-step explanation:

In order to find the median, you need to ut the numbers in either least to greatest form, or greatest to least (FIRST).

I'm gonna do both as an example.

Greatest to least:

14, 13, 9, 9, 7, 5, 3, 2, 1

Least to greatest:

1, 2, 3, 5, 7, 9, 9, 13, 14

It is REALLY important that you use ALL of the numbers you are given, even if there are two or more of the same number.

The next thing you need to do is find the number that is in the middle.

It will be the same for both least to greatest AND greatest to least.

You can either count one from either side, going in a pattern, OR you can count how many there is, divide it by 2, and whatever answer you get, count that many times over from one side.

In this case, your answer goes like this:

since there are 9 numbers, and 9 is not an even number, you will have only one median. Having 2 medians IS normal and it IS ok.

In this case, you want to go down one number (from 9) and divide that. So you do 8 divided by 2, which is 4. Count that many times over and you have your answer, 7.

I hope this helped you!

Have a great dayyyy

A community swimming pool has a deep end and a shallow end. The volume of water in the deep end can be represented by (2x2+12x+10) ft3 and the volume of the water in the shallow end can be represented by (4x2−100)ft3.

Write the equivalent expression ("simplified") that represents the total volume of the water in the pool in ft3.

Answers

Answer:

The total volume of water in the pool  = ( 6x^3 + 12x^2 - 90x ) ft^3

Step-by-step explanation:

The volume of water in the deep end = (2x^3 + 12x2 + 10x) ft^3

The volume of water in the shallow     =  (4x^3 -100x) ft^3

The total volume of water in the pool  = (2x^3 + 12x2 + 10x)  +  4x^3 -100x)

                                                              = ( 6x^3 + 12x^2 - 90x ) ft^3
