Step-by-step explanation:

Mixture:

17 gal 30% contains:  17x 30% = 5.10 gal pure juice

 Second brand:

8 gal 48% contains:  8x40% =  3.84   gal pure juice

5.10 − 3.84 = 1.26   gal

1.26   gal is  coming  from 9 gal of first  brand

The percentage of first brand  is:

(1.26/9) x100  =  14 %   pure juice.

Answer:

2

Step-by-step explanation:

Find a linear dimension of the image, such as a length, width, height, altitude, etc. Find the corresponding dimension in the original. Divide the length of the image by the original length.

Linear dimension in the image: A'B' = 6

Corresponding length in the original: AB = 3

divide image/original

scale factor = 6/3 = 2

Answer: 2

Answer:

66 cm (Option B)

Step-by-step explanation:

The formula for the circumference of a circle is C = 2πr, so plug the values into the formula.  The radius, (r) of a circle is one half of the diameter, so split 21 is half to get a radius of 10.5.  Use 3.14 for π.  

C = 2πr

C = 2(3.14)(10.5)

C = 6.28 × 10.5

C = 65.94

Rounded to the nearest unit, you get a answer of 66 cm.  

Hope this helps!  :)

30% + 4% = 34%

Answer:

[tex]A=3276\ ft^2[/tex]

Step-by-step explanation:

Given that,

The sides of a parallelogram are 49 feet and 78 feet. The measure of the angle  between these sides is 59º.

We need to find the area of the parallelogram.

Using trigonometry,

[tex]\sin(59)=\dfrac{h}{49}\\\\h=\sin(59)\times 49\\\\h=42.00\ ft[/tex]

We know that,

Area = base (b) × height (h)

So,

[tex]A=78\times 42.00\\\\A=3276\ ft^2[/tex]

So, the area of the parallelogram is equal to [tex]3276\ ft^2[/tex].

convert to 8/3÷10/9

that gives 8/3÷9/10

then we calculate 4 x 3/5

which = 12/5

Answer:

12/5 or  2 2/5

Step-by-step explanation:

Firstly, change the mixed form into an improper fraction.

8/3 ÷ 10/9

To find the answer, you have to multiply by the reciprocal of 10/9.

Step-by-step explanation:

It is helpful to recognize 128 = 2^7. Then you know ...

If you don't know that, you can use the change of base formula:

Answer:

x = 29°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180° for x

x = 180° - (128 + 23)° = 180° - 151° = 29°

Answer:

[tex]x=8[/tex]

Step-by-step explanation:

First, I wanna point out a minor mistake, are we supposed to figure out x?

If we are, let's start.

[tex]-12x+16-4x=-112.[/tex]

We don't need the [tex]16.[/tex]

We subtract the 16 from both sides.

SImplify, =[tex]16x=128[/tex]

Also, group like terms, and add similar elements.

Answer:

x = 8

Step-by-step explanation:

-12x + 16 - 4x = -112

Combine like terms on the left side.

-16x + 16 = -112

Subtract 16 from both sides.

-16x = -128

Divide both sides by 16.

x = 8

Check:

-12x + 16 - 4x =

= -12(8) + 16 - 4(8)

= -96 + 16 - 32

= -80 - 32

= -112

-112 = -112

x = 8 is correct.

Answer: x = 8

Answer:

B

Step-by-step explanation:

You first must find the conversion rate. Since you know a 4 ft tall object produces a 5 foot long shadow, you simply divide 4 by 5. This gives you 0.8. Now that you have your conversion rate, you multiply it by the shadow the tree casts, that being 125, and your answer is B, 100.
