12 hours, you can use proportions, miles/hours. 56/1=672/x. x=12.

6-8x=-3x+11

-8x+3x=11-6

-5x=5

x=-1

The first step is to isolate the variable, then you solve. Hope this helps, brainliest if you can.

Answer if you know

Arlecino [84]

I've attached a plot of one such cross-section (orange) over the region in the x-y plane (blue), including the bounding curves (red). (I've set $y=1.25$ for this example.)

The length of each cross section (the side lying in the base) has length determined by the horizontal distance $x$ between the y-axis $x=0$ and the curve $y=\sqrt x$ . In terms of $y$ , this distance is $x=y^2$ . The height of each cross section is twice the value of $y$ , so the area of each rectangular cross section should be $2y^3$ .

This means the volume would be given by the integral

$\displaystyle\int_0^22y^3\,\mathrm dy$

Madison read 1/2 of a book in the morning, and she read some more at night. By the end of the day she still had 2/5 of the book

Answer: 1/10

Step-by-step explanation:

At the end of the day, she still had 2/5 of the book to read. Which meant that she had read 3/5 of the book. Since she read 1/2 of the book in the day, we would read 3/5 - 1/2 = 6/10 - 5/10 = 1/10 of the book at night.

Prove that if a quadrilateral has four equal sides and one right angle, then the quadrilateral is a square

mars1129 [50]

So lets ABCD are the sides of the square and AB=CD, AC=BD and the Angle ABC = 90 so therefore by making a diagonal we can use the SAS or SSS congruency for two triangles, so we can prove two triangles are equal and that is why the shape is square.

Micayla wants the print shop to reduce the size of her painting but keep the ratio of length to width so that it will fit her fr

marissa [1.9K]

Answer:

The width of the frame must be 12 inches (15in by 12in)

Step-by-step explanation:

Given

See attachment for painting and frame

Required

Determine the dimension of the frame

To do this, we make use of the following scale ratio.

$Scale = Length : Width$

For the painting,

$Scale = 20: 16$

For the frame,

$Scale = 15: w$

Since she wants to maintain the same ratio; both scale must be the same.

i.e.

$15 : w = 20 : 16$

Express as fraction

$\frac{w}{15} = \frac{16}{20}$

$\frac{w}{15} = 0.8$

Make w the subject

$w = 15 * 0.8$

$w = 12$

<em>The width of the frame must be 12 inches i.e. 15in by 12in frame</em>
