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
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.)
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?
Answer:
425 min$80Step-by-step explanation:
The equation to reflect the monthly plans:
Plan A f(x) = 0.16x + 12Plan B g(x) = 0.12x + 29We 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 minutesThe cost is:
$0.16*425 + $12 = $80If we put on equations
y=0.16x+12y=0.12x+29Amount of calling is x and cost is y
solve
0.16x+12=0.12x+290.04x=17x=17/0.04x=425minCost
0.12(425)+29=$80How do I graph these points on a graph?
(-1/2, -3/2)
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
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.

Factor using the x method
( please do not answer without showing work )
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)

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)
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 .Find the area of a semicircle with radius r

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 ]
My explanation isn't that good so I would suggest watching the math antics video which is named "Circles, Circumference And Area"
You and your friends went to dinner and you decided to pay for everyone's meal. The total bill came to $65.00. You decided to give the waiter a 20% tip before tax. You also had to pay 6.8% sales tax. How much did you have to pay in all?
Answer:
In total I had to pay $ 82.42.
Step-by-step explanation:
Since I and my friends went to dinner and I decided to pay for everyone's meal, and the total bill came to $ 65.00, and I decided to give the waiter a 20% tip before tax and also had to pay 6.8% sales tax, for To determine how much did I have to pay in all, the following calculation should be performed:
65 + (65 x 0.2) + (65 x 0.068) = X
65 + 13 + 4.42 = X
78 + 4.42 = X
82.42 = X
Therefore, in total I had to pay $ 82.42.
