Answer:

Evan would have six 1/3 toast pieces.

Step-by-step explanation:

Cutting a single piece of toast into thirds would give you three 1/3 pieces, but because he cut 2 pieces in 1/3 you will have to multiply 3 × 2

To draw the model first draw two squares as toast pieces, then you want to draw two lines down each square, evenly and make sure to count out 6 rectangles, or 1/3 pieces.

Answer:

6 sub-pieces, each 1/3 of a full piece of toast

Step-by-step explanation:

Divide "2 pieces of toast" by "1/3 piece of toast:" This results in:

2 pieces

------------- = 6 sub-pieces

1/3

Suppose you lay out the 2 pieces of toast. You then cut them up, one at a time, cutting each full pieces into 3 sub-pieces. Obviously you get 3 (1/3 pieces). Now repeat that with the other full piece; again, you get 3 (1/3) pieces, or a total of 6 from the original 2 full pieces.

Answer:

1.2 cm

Step-by-step explanation:

Quadrilateral circumscribing a circle is a quadrangle whose sides are tangent to a circle inside it (see attached diagram).

The area of circumscribed quadrilateral is

$A=p\cdot r,$

where $p=\dfrac{a+b+c+d}{2}$ is semi-perimeter and r is radius of inscribed circle.

In your case, $A=12\ cm^2$

If a quadrilateral is circumscribed over the circle, then the sum of opposite sides is equal, so

$a+c=b+d=10\ cm,$

$P=10+10=20\ cm\\ \\p=\dfrac{20}{2}=10\ cm$

Now

$12=10\cdot r\Rightarrow r=\dfrac{12}{10}=1.2\ cm$

Find the roots of h(t) = (139kt)^2 − 69t + 80

Sonbull [250]

Answer:

The positive value of $k$ will result in exactly one real root is approximately 0.028.

Step-by-step explanation:

Let $h(t) = 19321\cdot k^{2}\cdot t^{2}-69\cdot t +80$ , roots are those values of $t$ so that $h(t) = 0$ . That is:

$19321\cdot k^{2}\cdot t^{2}-69\cdot t + 80=0$ (1)

Roots are determined analytically by the Quadratic Formula:

$t = \frac{69\pm \sqrt{4761-6182720\cdot k^{2} }}{38642}$

$t = \frac{69}{38642} \pm \sqrt{\frac{4761}{1493204164}-\frac{80\cdot k^{2}}{19321} }$

The smaller root is $t = \frac{69}{38642} - \sqrt{\frac{4761}{1493204164}-\frac{80\cdot k^{2}}{19321} }$ , and the larger root is $t = \frac{69}{38642} + \sqrt{\frac{4761}{1493204164}-\frac{80\cdot k^{2}}{19321} }$ .

$h(t) = 19321\cdot k^{2}\cdot t^{2}-69\cdot t +80$ has one real root when $\frac{4761}{1493204164}-\frac{80\cdot k^{2}}{19321} = 0$ . Then, we solve the discriminant for $k$ :

$\frac{80\cdot k^{2}}{19321} = \frac{4761}{1493204164}$

$k \approx \pm 0.028$

The positive value of $k$ will result in exactly one real root is approximately 0.028.

Clara opened a bank account. She deposited $95 each month for 10 months. Her bank charged her 2$ each month to use the account.

ollegr [7]

The answer is C.. because if you do 95x100 you get 950 and then you need to do 2x10 and you get 20, so then you subtract 20 from 950 and you will get $930
