Since variables x and y are in direct proportion,

Y = 12.5/25 x 40
Y = 0.5 x 40
Y = 20.

Denise mixed 1 4/5 ounces of blue paint with 2 1/10 ounces of yellow paint. How many ounces of paint did Denise mix?

fenix001 [56]

Answer:

Hence total 3.9 ounces of paint was used to make the mixture.

Step-by-step explanation:

Denise mixed $1\frac{4}{5}$ ounces of blue paint with $2\frac{1}{10}$ ounces of yellow paint.

Now we are asked to find how many ounces of paint did Denise mix.

i.e. we are asked to find the total number of paint used to form the mixture.

We know that:

$1\frac{4}{5}=\dfrac{9}{5}$ and $2\frac{1}{10}=\dfrac{21}{10}$

Hence total paint used= $\dfrac{9}{5}+\dfrac{21}{10}$

= $\dfrac{39}{10}=3.9$

Hence total 3.9 ounces of paint was used to make the mixture.

Find ""k"" so that the 58 unit diagonal of a rectangle can have an aspect ratio of 15:8. Then find the length and width of the r

irina [24]

Step-by-step explanation:

The area of any 2-d quadrilateral is equal to the base of the shape times the height, though we can just sub in length and width here. The key bits of information here is the aspect ratio (4:3) and the given area (300 in^2).

So far this gives us L∗W=300in2

Now, the aspect ratio given implies for every 4 inches in length, there will be 3 inches in width. This allows us to factor out a 4 and a 3 from the Length and Width respectively and give them the same constant variable, like so:

4x∗3x=300in2

Now, some might be tempted to go ahead with 12x here, but let’s expand the left side out to see what’s really going on:

4∗x∗3∗x=300in2

From here, let’s resolve like terms Our constants will multiply together and give us 12, and x * x of course gives us x^2 to give us the following:

12x2=300in2

From here, simply divide through by 12 to isolate x on one side,x2=25

And finally take the square root of both sides to work out what your common factor is,

x=5

Now that we have out common factor, let’s plug it back into our original formula to find our Length and Width, like so.

(4∗5)in∗(3∗5)in=300in2

20in∗15in=300in2

Therefore, the Length of our rectangle is 20in, and the Width of our rectangle is 15in

HELPPP!!!! 10 PTS!!<br><br> Find the missing information <br><br> x = _____ m angle A = ____

saveliy_v [14]

The triangle is isosceles, so the bottom angles have the same measure. So, the angles measure 2x, 3x+5 and 3x+5.

The sum of the interior angles of a triangle is 180, so we have

$2x+(3x+5)+(3x+5)=8x+10=180 \iff 8x=170 \iff x=\dfrac{170}{8}=\dfrac{85}{4}$

So, angle A measures

$3\left(\dfrac{85}{4}\right)+5 = \dfrac{275}{4}$
