Answer 1

Answer:

Try 5 first. If that is marked wrong, try 5.07

Step-by-step explanation:

Estimate means put your calculator on the other side of the room. You are to do this in your head.

78 is nearly 80

69 is nearly 70

29 is nearly 30

So now do the question

80 + 70 = 150       because 8 and 7 = 15.

150 / 30 = 50 because 15/3 = 5

So the answer that should be right for this question should be 5

Let's see how close that is.

78 + 69 = 147

147 / 29 = 5.07

Answer 2

9514 1404 393

Answer:

  5

Step-by-step explanation:

To estimate the quotient, round the numerator and denominator, then find the quotient of the rounded numbers.

  (78 +69)/29 ≈ (80 +70)/30 = 150/30 = 5

A good estimate of the quotient is 5.

_____

Additional comment

IMO, an estimate should also be accompanied by an estimate of the error. Here, the numerator is increased by 3 units to get 150, so is about 3/147 ≈ 2% high. The denominator is increased by 1 unit to get 30, so causing the estimate to be approximately 1/29 ≈ 3.3% low. Overall, this means the estimate is on the order of 2% -3.3% = -1.3% from the actual value. That is, it is on the order of 1.3% low. (It is actually about 1.361% low.)


Related Questions

A phone company offers two monthly plans. Plan A costs $12 plus an additional $0.16 for each minute of calls. Plan B costs $29 plus an additional $0.12 for
each minute of calls.

For what amount of calling do the two plans cost the same?

What is the cost when the two plans cost the same?

Answers

Answer:

425 min$80

Step-by-step explanation:

The equation to reflect the monthly plans:

Plan A f(x) = 0.16x + 12Plan B g(x) = 0.12x + 29

We need to find the value of x when f(x) = g(x):

0.16x + 12 = 0.12x + 290.16x - 0.12x = 29 - 120.04x = 17x = 17/0.04x = 425 minutes

The cost is:

$0.16*425 + $12 = $80

If we put on equations

y=0.16x+12y=0.12x+29

Amount of calling is x and cost is y

solve

0.16x+12=0.12x+290.04x=17x=17/0.04x=425min

Cost

0.12(425)+29=$80

Answer:

Start at origin (0,0)

Move 1/2 units left

Move 1 and 1/2 units down

Place your point

Step-by-step explanation:

Start at the origin (0,0)

Move 1/2 units to the left

Then move 1 1/2 units down, and place your point.

The first coordinate is locating the position horizontally, or on the x axis

The second coordinate is locating the position vertically, or on the y axis.

If there is a negative number on the x coordinate, the first one, you move left.

If positive, you move right.

If there is a negative number on the y coordinate, the second one, you move down.

If positive, you move up.

Describe how the area of a rectangle will change if its width remains constant but its length is halved

Answers

Answer:

Step-by-step explanation:

Area of a rectangle is given as length times breadth. Mathematically,

A = l * b

If the length is halved and the breadth is constant, then we have

A = l/2 * b

A = lb/2

From the above, the area of a rectangle is lb, while the area of the hypothetical rectangle will be lb/2

This means that, if the length is halved, and the width is constant, then the area of the rectangle reduces by half.

Answers

Answer:

[tex]5(x + 10)(10x - 3)[/tex]

Step-by-step explanation:

We are factoring

[tex]50x^{2} + 485x - 150[/tex]

So:

((2•5^2x^2) +  485x) -  150

Pull like factors :

50x^2 + 485x - 150  =   5 • (10x^2 + 97x - 30)

Factor

 10x^2 + 97x - 30

Step-1: Multiply the coefficient of the first term by the constant   10 • -30 = -300

Step-2: Find two factors of  -300  whose sum equals the coefficient of the middle term, which is 97.

-300    +    1    =    -299

     -150    +    2    =    -148

     -100    +    3    =    -97

     -75    +    4    =    -71

     -60    +    5    =    -55

     -50    +    6    =    -44

     -30    +    10    =    -20

     -25    +    12    =    -13

     -20    +    15    =    -5

     -15    +    20    =    5

     -12    +    25    =    13

     -10    +    30    =    20

     -6    +    50    =    44

     -5    +    60    =    55

     -4    +    75    =    71

     -3    +    100    =    97

Step-3: Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -3  and  100

                    10x^2 - 3x + 100x - 30

Step-4: Add up the first 2 terms, pulling out like factors:

                   x • (10x-3)

             Add up the last 2 terms, pulling out common factors:

                   10 • (10x-3)

Step-5: Add up the four terms of step 4:

                   (x+10)  •  (10x-3)

            Which is the desired factorization

Thus your answer is

[tex]5(x + 10)(10x - 3)[/tex]

Answer:

[tex] \displaystyle \rm 5({x}^{} + 10)( 10x - 3)[/tex]

Step-by-step explanation:

we would like to factor out the following expression:

[tex] \displaystyle {50x}^{2} + 485x - 150[/tex]

notice that, in every term there's a common factor of 5 thus factor it out:

[tex] \displaystyle 5( {10x}^{2} + 97x - 30)[/tex]

now we have to rewrite the middle term as sum or substraction of two different terms in that case 100x-3x can be considered:

[tex] \displaystyle 5( {10x}^{2} + 100 - 3x - 30)[/tex]

factor out 10x:

[tex] \displaystyle 5( 10({x}^{2} + 10)- 3x - 30)[/tex]

factor out -3:

[tex] \displaystyle \rm 5( 10x({x}^{} + 10)- 3(x + 10))[/tex]

group:

[tex] \displaystyle \rm 5({x}^{} + 10)( 10x - 3)[/tex]

and we are done!

hence,

our answer is B)

Alicia hiked 3 3/4 miles for 8 Saturdays in a row.
Distance hiked = 3 3/4 × 8 = 30 miles

Then she hiked 5 1/4 miles for the next 4 Saturdays.
Distance hiked = 5 1/4 × 4 = 21 miles

Total distance hiked = 51 miles

Please (You can put answer only) Find the distance between the two points rounding to the nearest tenth (if necessary).
(4, -8) and (2, -4)

Answers

Answer:

12.16 u

Step-by-step explanation:

Given :-

Two points (4,-8) and (2,-4) is given to us.

And we need to find out the distance between the two points . So , here we can use the distance formula to find out the distance. As,

[tex]:\implies[/tex] D = √{(x2-x1)² + (y2-y1)²}

[tex]:\implies[/tex] D =√[ (4-2)² +(8+4)²]

[tex]:\implies[/tex] D =√[ 2² +12²]

[tex]:\implies[/tex] D =√[ 4 +144]

[tex]:\implies[/tex] D = 12.16

Hence the distance between the two points is 12.16 units .

(The answer is 4.5) Distance between formula is √(xB-xA) ²+ (yB-yA) ² now you plug in your points (4, -8) (2, -4)
√(2-4) ² +(-4 - -8) ² which would then get you √(-2) ² + 4 ² then √4+16 to √20 which would be 4.47 which you round up 4.5. (First set of points(4, -8) 4=xA,-8=yA) (Second set of points=(2, -4) 2=xB, -4=yB) √ is a square root, ² is a second power it means whatever the number associated with it is getting multiplied by itself or two times so example 5 ² is 5x5 or 7 ² is 7x7 or 9 ² is 9x9.

THANK YOU......

Answer:

To calculate the area of a semicircle

We are gonna have to use the formula :

[tex]\frac{1}{2}[/tex] π r² [ that is the formula to calculate the area of a semicircle ]

Step-by-step explanation:

If we want to calculate the radius of a semicircle with 4 ft --

we would first write the formula which is "[tex]\frac{1}{2}[/tex] π r²"

Then, you would write: [tex]\frac{1}{2}[/tex] π (4 ft)²

After that, you would write:  [tex]\frac{1}{2}[/tex] (3.14)(16)

Type that into a calculator and you would get 25.12  as your answer

--

Why did we write 3.14 and 16? [ [tex]\frac{1}{2}[/tex] (3.14)(16) ]

Bc, the first digits of pi are 3.14 .

We wrote 16 because 4² = 16 [ 4x4=16 ]
