Flow is given as, F = - 4 gallon per minute into small tank.

( Since, flow is negative )

Volume of oil in large tank, V = 600 gallons.

Now,

Volume of oil has been moved :

[tex]v = F \times t\\\\v = -4 \ gallons/min \times\ 32\ min\\\\ v = -128\ gallons[/tex]

Therefore, 128 gallons of oil has been moved to small tank.

Hence, this is the required solution.

Answer:

128 gallons, into the small tank.  I think its the second option for the last box, not 100 percent sure but i did the question so yea :D

Step-by-step explanation:

Check the picture below.

[tex]sin(35^o)=\cfrac{\stackrel{opposite}{12}}{\underset{hypotenuse}{BD}}\implies BD=\cfrac{12}{sin(35^o)} \\\\[-0.35em] ~\dotfill\\\\ \textit{Law of sines} \\\\ \cfrac{sin(\measuredangle A)}{a}=\cfrac{sin(\measuredangle B)}{b}=\cfrac{sin(\measuredangle C)}{c} \\\\[-0.35em] ~\dotfill[/tex]

[tex]\cfrac{sin(52^o)}{BD}=\cfrac{sin(102^o)}{CD}\implies CD=\cfrac{BD\cdot sin(102^o)}{sin(52^o)} \\\\\\ CD=\cfrac{\frac{12}{sin(35^o)}\cdot sin(102^o)}{sin(52^o)}\implies CD=\cfrac{12\cdot sin(102^o)}{sin(35^o)\cdot sin(52^o)}\implies CD\approx 26.0[/tex]

Answer:

Answer:

three thousand three hundred and fifty.3,350

Step-by-step explanation:

the question given was:1/4 take a speech, so how many?: one fourth, if you divide 13,400 by 4 its 3,350. that is one fourth  of 13,400. So, if you add 3,350 four times, it would be 13,400.

2. 4 x 90 = 360 degrees

3. 1 1/2 x 90 = 135 degrees

4. 2 1/3 x 90 = 210 degrees

5. 2/9 x 360 = 80 degrees

6. 3 3/8 x 360 = 1,215 degrees

For Lauren's tower which he drew using only similar quadrilaterals the statement B is correct, which is the quadrilaterals are different shapes but the same size.

Quadrilateral is the plane shape which is closed polygon having which is made by using the four sides, four angles and four vertices.

The sum of all the interior angle in a quadrilateral is equal to 360 degrees.

The two quadrilateral are said to be a similar quadrilateral when the quadrilaterals are all the same size and shape.

Here, Lauren drew a tower using only similar quadrilaterals. Let's check all the statement about the quadrilaterals given as,

As for the similar quadrilaterals, quadrilaterals are all the same size and shape. Thus, the option B is the correct option.

Hence, for the Lauren's tower which he drew using only similar quadrilaterals the statement B is correct, which is the quadrilaterals are different shapes but the same size.

Answer:

a = -√3/3

b = 2√3/3

Step-by-step explanation:

Finding the slope of the tangent at C  by finding the derivative:

x^2 + y^2 = 1

2x + 2y y' = 0

2y y' = -2x

y' = -2x / 2y = -x/y

So the slope = - 1/2 / √3/2

= -1/2 * 2/√3

= -1/√3

= -√3/3

Using the point-slope form of a straight line

y - y1 = m(x - x1)

y - √3/2 = -√3/3(x - 1/2)

y - √3/2 =  -√3/3 x +√3/6

y =  -√3/3 x + √3/6 +√3/2

y =  -√3/3 x + 4√3/6

y = -√3/3x +  2√3/3

Answer:

The value of x is D. 37°

Step-by-step explanation:

No need for math on this one, the angle next to x is 71° and is significantly bigger, so the only answer could be 37°.

The value of x will be 37°.

What is Vertically opposite angles?

Vertically Opposite Angles are the angles opposite each other when two lines cross.

Given that;

This figure has two intersecting lines and a ray.

Now, By the definition of vertically opposite angles, we get;

x° + 71° = 108°

Then, Solve for x as;

x° + 71° = 108°

Subtract 71 both side;

x° + 71° - 71° = 108° - 71°

x° = 37°

Thus, The value of x will be 37°.

Given:

The stand sold 4 cherry snow cones for every 1 lemon snow cone sold.

There were 30 more cherry snow cones than lemon snow cones sold yesterday.

To find:

The number of snow cones which were sold altogether.

Solution:

Let x be the number of lemon snow cone sold.

The stand sold 4 cherry snow cones for every 1 lemon snow cone sold.

So, number of cherry snow cone sold = 4x

There were 30 more cherry snow cones than lemon snow cones sold yesterday.

[tex]4x-x=30[/tex]

[tex]3x=30[/tex]

Divide both sides by 3.

[tex]x=\dfrac{30}{3}[/tex]

[tex]x=10[/tex]

Total number of snow cones sold is

[tex]\text{Total number of snow cones sold }=x + 4x[/tex]

[tex]\text{Total number of snow cones sold }=5x[/tex]

[tex]\text{Total number of snow cones sold }=5(10)[/tex]

[tex]\text{Total number of snow cones sold }=50[/tex]

Therefore, 50 snow cones were sold altogether.

Answer:

60

Step-by-step explanation:

Summing the ratios gives 1+2+2=5

300/5 = 60

(1 x 60) + (2 x 60) + (2 x 60)

(60) + (120) + (120) = 300

Hence the least share is 60

The other two shares are equal which is 120
