Based on the calculations, the slowest rate is equal to 4 gallons per minute.

Given the following data:

Let's assume the boat would sink if it takes in more than 20 gallons of water.

Conversion:

Translating the word problem into an algebraic expression, we have;

[tex]\frac{12}{0.4} \times 3 - \frac{12}{0.4} \times x\geq 30\\\\\frac{36}{0.4}-\frac{12x}{0.4} \geq 30\\\\90-\frac{12x}{0.4} \geq 30\\\\\frac{12x}{0.4} \geq90+30\\\\\frac{12x}{0.4} \geq120\\\\12x \geq120 \times 0.4\\\\12x \geq 48\\\\x\geq 4[/tex]

Therefore, the slowest rate is equal to 4 gallons per minute.

Answer:

about 50

Step-by-step explanation:

Ten teaspoons equal 50 milliliters using the conversion factor 1 tsp = 5 mL.

1 tsp = 5 mL

By multiplying 10 teaspoons by the conversion factor (10 tsp × 5 mL/1 tsp)

10 teaspoons × 5 mL/1 tsp = 50 milliliters

So, there are 50 milliliters in 10 teaspoons.

The conversion factor enables us to maintain the same quantity while converting between different units of measurement. It is an essential tool for performing precise conversions in a variety of disciplines including chemistry, medicine and cooking. For practical applications unit conversions must be understood in order to ensure accurate measurements and consistent outcomes across various measurement systems. Since milliliters are a more commonly used unit of measurement, the conversion in this instance enables us to express the volume of teaspoons in that unit.

2,094 cm^3

==========================================================

Explanation:

The diameter of 20 cm divides in half to the radius r = 10 cm.

The height is h = 20 cm.

V = volume of the cone

V = (1/3)*pi*r^2*h

V = (1/3)*pi*10^2*20

V = 2,094.3951023932 is approximate

I used my calculator's stored version of pi when computing the volume

That value then rounds to 2,094 cm^3 when rounding to the nearest whole number.

p=2l+2w

p=2(57)+2(47)

p=208 feet

The perimeter of rectangle is 208 ft.

The perimeter of a rectangle is the total length or distance of its boundary on all sides. The perimeter of a rectangle is a linear measure and is expressed in linear units of meters, feet, inches, or yards. Let us first understand the two main properties of a rectangle.

Therefore, the Perimeter of a rectangle = 2(l + w).

Given:

length = 47 ft

width = 57 ft

So, the perimeter of rectangle

= 2( l + w)

=2( 47 + 57)

= 2 x 104

= 208.

Hence, the perimeter of rectangle is 208 ft

The amount of wrapping paper needed for the square pyramid gift box is: 96.72 in.².

Surface area of a square pyramid = area of the square base + area of the 4 triangular faces = s² + 4(1/2bh).

We are asked to find the amount of wrapping paper that would be needed to wrap the gift box, which is the surface area of the gift box that has a square pyramid shape.

Given the following dimensions of the gift box:

s = 5.2 in.

b = 5.2 in.

h = 6.7 in.

Plug in the values into s² + 4(1/2bh):

Surface area of a square pyramid = 5.2² + 4(1/2 × 5.2 × 6.7).

Surface area of a square pyramid = 96.72 in.²

315

Step-by-step explanation:

360 - 45 = 315

since a full circle is 360 degrees that is why we take away the 45 degrees.

Answer:

See below.

Step-by-step explanation:

Given numbers :-

⇒ 176, 231, 247, 256, 272, 299, 325, 343, 366, 375

⇒ Median = 272 + 299 / 2 = 285.5

⇒ Mean = 2890/10 = 289

(a) median if 375 becomes 265

⇒ 176, 231, 247, 256, 265, 272, 299, 325, 343, 366

⇒ New median = 265 + 272 / 2 = 268.5

⇒ Decreases by 17

(b) mean if 375 becomes 265

⇒ New mean = 2890 - 110 / 10 = 2780/10 = 278

⇒ Decreases by 11

A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.

Here, we have to points (1.5,0) and, (0,-3)

So, by using the formula of equation of straight line of two-point form, we get,

(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )

=>3x-1.5y=4.5

y=2x-3

Again,

Here, we have to points (-1.5,0) and, (0,-3)

So, by using the formula of equation of straight line of two-point form, we get,

(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )

=>3x+1.5y=-4.5

y=2x+3

Here, we have to points (1.5,0) and, (0,-3)

So, by using the formula of equation of straight line of two-point form, we get,

(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )

=>-3x+1.5y=4.5

y=-2x+3

Here, we have to points (-1.5,0) and, (0,3)

So, by using the formula of equation of straight line of two-point form, we get,

(y-y_1)/(x-x_1 )=(y_2-y_1)/(x_2-x_1 )

=>3x+1.5y=4.5

y=-2x-3

Answer: 3.5 hours

Step-by-step explanation:

From the question, we are informed that Ray's burns 326 calories every hour. We are further told that he ate a doughnut that had 320 calories, and a latte had 820 calories. The total calories will be:

= 320 + 820

= 1140 calories

The number of hours needed to burn the calories will be the total calories divided by the amount of calories burnt in an hour. This will be:

= 1140/326

= 3.5 hours

Answer:

AB = 36

Step-by-step explanation:

Since E is the midpoint of AB, then

AE = EB , substitute values

4x + 6 = 10x - 12 ( subtract 10x from both sides )

- 6x + 6 = - 12 ( subtract 6 from both sides )

- 6x = - 18 ( divide both sides by - 6 )

x = 3

Thus

AB = AE + EB = 4x + 6 + 10x - 12 = 14x - 6 = 14(3) - 6 = 42 - 6 = 36

Answer:

5x + 4y = - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

4x - 5y = 20 ( subtract 4x from both sides )

- 5y = - 4x + 20 ( divide all terms by - 5 )

y = [tex]\frac{4}{5}[/tex] x - 4 ← in slope- intercept form

with slope m = [tex]\frac{4}{5}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{4}{5} }[/tex] = - [tex]\frac{5}{4}[/tex] , thus

y = - [tex]\frac{5}{4}[/tex] x + c ← is the partial equation

To find c substitute (- 4, 3) into the partial equation

3 = 5 + c ⇒ c = 3 - 5 = - 2

y = - [tex]\frac{5}{4}[/tex] x - 2 ← in slope- intercept form

Multiply through by 4

4y = - 5x - 8 ( add 5x to both sides )

5x + 4y = - 8 ← equation in standard form
