Answer:

3/4

Step-by-step explanation:

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.

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.

Answer:

Slope is -2/5 and y-intercept is 4

Step-by-step explanation:

Because of y=mx+b

b is always going to be the y-intercept and mx is going to be the slope.

Answer:

Slope is -2/5 and y-intercept is 4

\

Because of y=mx+b

b is always going to be the y-intercept and mx is going to be the slope.

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

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.

Answer:  8. 1.2 × 10⁻⁶  1.2 × 10⁻³  1.2 × 10³  1.2 × 10⁵  1.2 × 10⁶

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)

The total number of decimal places in the factors will be the number of decimal places in the product. 0.002 has 3 decimal places. 0.0004 has 4 decimal places. Total of 7. SO "0" decimal . then six 0's then the multiplied number 8 in 7th place.

Answer:

x=-31/4

Step-by-step explanation:

Cross multiply and bring 3 to the opposite side.

3(3x+8) =5x-7

9x+24=5x-7

Bring all the x to one side and the numbers to the other

9x-5x=-7-24

4x=-31

x=-31/4

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

Answer:

24% of a hundred is 24

Step-by-step explanation:

use fractions to help you solve this.

The measure of length ZV, ZY, ZU, TY, and XV are 56, 30, 50, 60, and 78.

If Z is the centroid of triangle TUV, then the following are true:

ZV = 2ZX

Given that ZX = 28,

ZV = 2(28)

ZV = 56

Similarly, TZ = 2ZY

60 = 2ZY

ZY = 60/2

ZY = 30

Also, ZU = 2WZ

ZU = 2(25)

ZU = 50

TY = 2ZY

TY = 2(30)

TY = 60

XV = XZ + ZY

XV = 28 + 50

XV = 78

Therefore the measure of length ZV, ZY, ZU, TY, and XV are 56, 30, 50, 60, and 78.
