Answer:

The result is 19

Step-by-step explanation:

3^{2}  + (5-2)x4 - 6/3

Step 1: Parenthesizing (5-2)=3

3^{2}  + 3x4 - 6/3

Step 2: Exponentiation 3^{2}=9

9  + 3x4 - 6/3

Step 3: Multiplication and division 3x4=12 and 6/3=2

9  + 12 - 2

Step 4: Addition and subtraction 9+12=21, and 21-2=19

21-2

19

The operations are ordered from highest to lowest in the order:

1. Parenthesizing,

2. Factorial,

3. Exponentiation,

4. Multiplication and division,

5. Addition and subtraction.

Hope this helps!

Answer: 21

Step-by-step explanation:

To work this out you will need the help of BIDMAS:

1. Brackets

2. Indices

3. Division

4. Multiplication

5. Addition

6. Subtraction

You must work this out one after the other

First we must get rid of the brackets by multiplication since brackets are similiar to ×.

3^2 + (5-2) × 4 - 6/3

+ (5-2) =

+ × 5 + × -2 =

5-2

Since + is infront we multiply it by the whole bracket and remember:

Positive (+) × or ÷ Positive(+) = Positive (+)

Negative (-) × or ÷ Negative (-) = Positive (+)

Positive (+) × or ÷ Negative (-) = Negative (-)

Negative (-) × or ÷ Positive (+) = Negative (-)

Then indices are next:

3^2 + (5-2) × 4 - 6/3

3^2 =

3×3 =

9

Then division:

- 6/3 =

2

It is explained above, and also if there is the minus symbol on both the number then the answer will end up with a plus, but if there is a minus on only one number then the answer will have a minus.

But in this case since there is a minus in both the numbers, then the result would be 2.

So right now there is supposed to be this numbers:

9 + 2 × 4 + 2

So then we multiply;

+2 × 4

+8

Finally we add everything up:

9 + 2 + 8 + 2 = 21

So in the end the answer is 21.

−6x + 14 < −28 OR 9x + 15 ≤ −12. solve for x.
sasho [114]

Answer:

x>7 or x ≤ -3

Step-by-step explanation:

Solving the 1st inequality

-6x +14 < -28 --------------- (Collect like terms)

-6x < -28 - 14

-6x < - 42 -------------------- (Divide both sides by -6)

Note: If you decide an inequality expression by a negative value, the inequality sign changes)

-6x/-6 > -42/-6

x > 7

Solving the 2nd inequality

9x + 15 ≤ −12 ----------- (Collect like terms)

9x ≤ −12 - 15

9x ≤ −27 ------------------(Divide both sides by 9)

9

9x/9 ≤ −27/9

x ≤ -3

Bring both results together, we get

x>7 or x ≤ -3

The final result is complex (i.e. can't be combined together).

the hoover dam is 725 feet tall. how long would it take an object to fall from the top to the base of the dam? round the answer
Alinara [238K]

Answer:

45.05 seconds

Step-by-step explanation:

Use the formula: d = vi t + \frac{1}{2} at^{2}

d = distance      vi = initial velocity (m/s)    

t = time (s)     a = acceleration (m/s^{2})

m is meters and s is seconds. They are units of measurement so leave them be.

Assuming the object is simply dropped, the initial velocity is 0 since the object was not moving before it was dropped.

The distance is 725 feet, which is 220.98 meters.

The acceleration is 9.81m/s^{2} since that is the acceleration of Earth's gravity, aka free fall.

Time is what we are trying to find so just leave it as the variable t.

So plug the values into the equation:

220.98m = (0)(t) + \frac{1}{2} (9.81m/s^{2})(t)

220.98m = (4.905m/s^{2})(t)

45.0519877676s = t

t = 45.05s

Remember to pay attention to units because your answer will be wrong otherwise

1. Try It # 1 A company sells doughnuts. They incur a fixed cost of $25,000 for rent, insurance, and other expenses. It costs $0
Y_Kistochka [10]

Answer:

The y-intercept is 25000 . The intercept is the fixed cost of the doughnut selling company.

Step-by-step explanation:

In the question, it is given that the fixed cost is $25000 and the expense to produce each doughnut is $0.25.

It is required to find and identify the y intercept.

To do so, use the equation derived in previous part of the exercise to interpret the slope. Compare the equation with standard equation of the line.

Step 1 of 1

The total cost of the company is the sum of fixed cost and the expenses for the doughnut, C=0.25x+25000.

Compare the equation with general linear equation y=mx+c.

The y-intercept is 25000 .

The intercept is the fixed cost of the doughnut selling company.
