Answer:
72 Keychains
Step-by-step explanation:
120 feet = $3.25
divide 120 by 3.25 to find how much string can be bought with $1. The result is 36.923. Then multiply that number by the number of dollars allotted to buying string. 8*36.923= 295.384. This is the total number of feet of string they have. They use 1 foot for each key chain so they can make 295 keychains based on how much string they have.
35 beads = $2.59
Divide 35 by 2.59 to find how many beads can be bought with $1. The result is 13.514. Then multiply that number by the number of dollars allotted to buying beads. This comes out to 364.878. This means She can buy 364 beads. Each Key chain needs 5 beads so divide 364/5 getting a total of 72 keychains.
Since there aren't enough beads to make any more than 72 keychains, they can make a total of 72 keychains (even though there is extra string)
1/sin30 - √3/cos10 =4 prove it?
Step-by-step explanation:
1/sin10-√3/cos10
= (cos10 - √3sin10)/cos10sin10
multiplying 1/2 in denominator and numerator
= {(cos10/2) - (√3sin10/2)}/(cos10sin10/2)
= (cos60cos10 - sin60sin10)/(cos10sin10/2)
= cos(60 + 10)/(cos10sin10/2)
= cos70/(cos10sin10/2)
= 2cos70/cos10sin10
multiplying 2 on numerator and denominator
= 4cos70/2sin10cos10
=4cos70/sin20
=4cos70/cos70
= 4 proved

HELP!!! PLEASE TELL ME WHICH GRAPH GOES WHERE!!! DON'T IGNORE PLEASE!!!
So y=mx+b is still prevalent here even if it's an inequality. Meaning your slope AND y-intercept can help you. Even if it's in ax+by=c you can easily get the y alone into slope-intercept.
y<_3x+5 for example. For one, it is y is less than or equal to 3x+5. So the line shouldn't be dotted. So that leaves us with the two far-right graphs to look at. 5 is our y-intercept in the equation. So look at our graph and see which one has the line passing through 5. They both do. Okay, well we can still use our sign, it shows that y is LESS than 3x+5. So the shaded blue part should be on the right. If it was the other way around it would be the left. So our graph should be the far right for this equation.
Hope this helps... I know it's kind of messy. If you need any more help let me know. But I hope I outlined what to look for.

11a. 10⁻⁷
11 b i. 8 × 10⁻⁷
11 b ii. 0.0000008
Step-by-step explanation: 8: the image is a bit out of focus, so it's hard to tell what all the exponents are. Just remember that for negative exponents, the larger the number, the smaller the value.
9. Following the examples given, the exponent tells how many places to count from right to left to move the decimal from standard form to wavelength and vice-versa.
9b. Just put the numbers from standard form in order and find the corresponding color.
10. For multiplication, multiply the numbers to the left of the × and add the exponents of the 10. For division, Divide the numbers on the left and subtract the exponents of 10.
11a add the powers. Just like the first part of #10
11b same procedure as #10 (The more you practice, the more likely you will remember)

estimate √9.7+3.88×6.21
9514 1404 393
Answer:
a little more than 27
Step-by-step explanation:
Estimates are generally made by approximating the numbers using 1 or 2 significant digits. The idea is to do as much mental arithmetic as possible, not involving a calculator. Here, the estimate can be based on rounding the values like this:
√9.7 +3.88 × 6.21 ≈ √9 +4 × 6 = 3 +24 = 27 . . . estimated expression value
__
Another aspect of estimating is determining the approximate error involved.
We know that √9.7 will be more than √9 = 3, and less than √10 ≈ 3.16*. Its real value may be about 3.1.
3.88 is less than 4 by 0.12, or 3%. 6.21 is greater than 6 by .21, or 3.5%. So, the estimated product of 24 will be on the order of -3% +3.5% = 0.5% too low. Of course 1% of 24 is 0.24, so 1/2% will be about 0.12. Now, we are able to estimate that our estimate is about 0.2 units too low. (The actual value of the expression is an irrational number that rounds to about 27.2093.)
_____
* The value of 3.16 for √10 is not so hard to remember, because it is just slightly more than π ≈ 3.14.
__
Additional comment
Small percentages can usually be added and subtracted without introducing too much additional error. (The smaller the percentages, the less additional error is introduced.) Here, the error in our estimated product can be more accurately determined by computing ...
(1 -3%)(1 +3.5%) = 1 +0.5% -0.105% = 1 +0.395% . . . . . . (not 1 +0.5%)
That is, our product's actual value is 24.0948, not 24.12.

the product of the roots of a quadratic equation 2x²-5x+3=0 is 5/2 if it is correct give reason
9514 1404 393
Answer:
It is incorrect. The product is 3/2.
Step-by-step explanation:
The factored form of a quadratic with roots p and q can be ...
a(x -p)(x -q) = ax² -a(p+q) +apq
Then the product of the roots is the ratio of the constant to the leading coefficient:
pq = (apq)/a
In the given quadratic, that product is ...
pq = 3/2 . . . . . . not 5/2
The statement that the product of roots is 5/2 is incorrect. That value does not have the required relationship to the coefficients of the quadratic.
Lin runs 2 laps around a track in 8 minutes.
a. How many minutes per lap is that? 4
b. How many laps per minute is that?
c. If Lin runs 21 laps at the same rate, how long does it take her?
Answer:
Part a: 4 minutes
Part b: [tex]\frac{1}{4}[/tex] lap
Part c: 84 minutes or 1 hr and 24 minutes
Step-by-step explanation:
Part a:
Ok so you got part a right, it's 4 minutes.
Part b:
you would do [tex]\frac{2laps}{8min.}[/tex] that will give you [tex]\frac{1}{4}[/tex].
So it's a quarter of a lap per minute.
Part c:
For this one we know that it takes her 4 minutes just to complete one lap, and if they're doing 21 laps that means we'll multiply 21 and 4. That gives us 84 minutes, or 1 hr and 24 min.

What is the slope of a line which makes an angle of 45 degree with x-axis? *
Answer:
First we have to find slope m=Tan45°=1
so slope is 1.
Answer:
slope = 1
Step-by-step explanation:
The relationship between slope and the positive angle it makes with the x- axis is
slope = tanθ ( θ is the angle measured from the x- axis ), then
slope = tan45° = 1

325 divided by 2.5 show your work
Answer:
130
Step-by-step explanation:
325 ÷ 2.5
= 130
325 divided by 2.5 is equal to 130
To divide 325 by 2.5, we can simplify the calculation by multiplying both the dividend and the divisor by 10 to eliminate the decimal point.
Thus, 325 divided by 2.5 is equivalent to (325 * 10) divided by (2.5 * 10), which becomes 3250 divided by 25.
Dividing 3250 by 25 gives us the quotient of 130.
Therefore, 325 divided by 2.5 is equal to 130. By multiplying both the dividend and divisor by 10, we effectively remove the decimal point and simplify the division process.
