The height of the boat floating above the seafloor at high tide is 17.5 feet

The ratio of the similar sides of the triangles is equal to a constant. In order to determine how high the boat is, we will use the ratio below;

20/40 =x/35

Determine the value of x

40x = 20 * 35
40x =700

x = 700/40
x = 17.5feet

Hence the height of the boat floating above the seafloor at high tide is 17.5 feet

Answer: P=5.2 h=3 B=2

Step-by-step explanation:

To find P, you add everything except for 3 because P starts for perimeter of the bases and 3 is the height of the prism. So P would equal 5.2. Then to get h, it’s just 3 because that’s the height of the prism. Now for B, you just multiply 1x2 because that’s the area of the base and you only need one. If you’re looking for total surface area, the answer is 19.6 becasue the formula is Pxh+2B meaning perimeter x height plus 2 x B. But for lateral, the answer is 15.6 because it’s just Pxh (perimeter x height) hope this helps lol sorry it’s so long.

The weight in pounds of the contents in the container is 288 pounds.

The volume of right rectangular prism is obtained by multiplying all 3 dimensional measures of that prism.

Given

A shipping container in the shape of a right rectangular prism has a length of 16 feet, a width of 8 feet, and a height of 4. 5 feet.

The container is completely filled with contents that weigh, on average, 0. 50 pound per cubic foot.

The volume of the right rectangular prism is given by

[tex]\rm Volume = 16\times 8 \times 4.5\\\\ Volume=576 \ ft^3[/tex]

Since the volume obtained is in cubic foot, thus there can be as many as 408 cubic foots inside the container.

Since one cubic foot content weighs around 0.50 pounds, thus,

[tex]\rm 1 \ cubic \ foot=0.50 \ pounds\\\\ 576 \ ft^3=0.50 \times 576 =288 \ pounds[/tex]

Hence, the weight in pounds of the contents in the container is 288 pounds.

SIMILAR

Step-by-step explanation:

The lines are parallel to each other, and one of the angles are 90 degrees. That is the only info that you get. You need to be able to make sure that another angle besides the 90 degrees is similar. The lines are parallel to each other, meaning that the other two angles should be equal in measure. See, if the angle in the second triangle gets bigger, the lines wouldn't be parallel, would they?

The total cost function is the sum of the two given functions, and this is equal to:

c(t) = 190 + 70*t

We know that:

If she hires both of them for the same time t, then the total cost function will be given by the sum of the two above functions, we will get:

c(t) = p(t) + e(t)

c(t) = (115 + 25*t) + (55*t + 75)

c(t) = (115 + 75) + (55*t + 25*t)

Step-by-step explanation:

[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 3 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{\frac{1}{4}} \hookrightarrow \frac{\frac{\pi}{2}}{2\pi} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{1} \hookrightarrow \frac{2}{2\pi}\pi \\ Amplitude \hookrightarrow 3[/tex]

You will need the above information to help you interpret the graph. First off, keep in mind that although this looks EXACTLY like the sine graph, if you plan on writing your equation as a function of cosine, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the photograph on the right displays the trigonometric graph of [tex]\displaystyle y = 3cos\:2\pi{x} + 3,[/tex] in which you need to replase "sine" with "cosine", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the sine graph [photograph on the left], accourding to the horisontal shift formula above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the cosine graph [photograph on the right] is shifted [tex]\displaystyle \frac{1}{4}\:unit[/tex]to the left, which means that in order to match the sine graph [photograph on the left], we need to shift the graph FORWARD [tex]\displaystyle \frac{1}{4}\:unit,[/tex]which means the C-term will be positive, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{\frac{1}{4}} = \frac{\frac{\pi}{2}}{2\pi}.[/tex]So, the cosine graph of the sine graph, accourding to the horisontal shift, is [tex]\displaystyle y = 3cos\:(2\pi{x} - \frac{\pi}{2}) + 3.[/tex]Now, with all that being said, in this case, sinse you ONLY have a graph to wourk with, you MUST figure the period out by using wavelengths. So, looking at where the graph hits [tex]\displaystyle [-\frac{1}{4}, 0],[/tex]from there to [tex]\displaystyle [\frac{3}{4}, 0],[/tex]they are obviously [tex]\displaystyle 1\:unit[/tex]apart, telling you that the period of the graph is [tex]\displaystyle 1.[/tex]Now, the amplitude is obvious to figure out because it is the A-term, but of cource, if you want to be certain it is the amplitude, look at the graph to see how low and high each crest extends beyond the midline. The midline is the centre of your graph, also known as the vertical shift, which in this case the centre is at [tex]\displaystyle y = 3,[/tex]in which each crest is extended three units beyond the midline, hence, your amplitude. So, no matter how far the graph shifts vertically, the midline will ALWAYS follow.

The sheet used by Mario and Patience which is going to warm up the quickest, and, therefore, bake the cookies the fastest is copper sheet.

The specific heat of a substance is the amount of heat needed, to raise the temperature of the of one gram of substance by unit degree Celsius.

The specific heat capacity of the substance can be given as,

[tex]C=\dfrac{Q}{m\Delta T}[/tex]

Here, (m) is the mass of the substance, (Q) is heat energy and

is the change in temperature.

The above formula can be rewritten as,

[tex]{Q}={m\Delta T}C[/tex]

By this formula, we can say that the heat energy is directly proportional to the specific heat of the substance.

Thus the value of heat energy required to warm up the substance will be higher with the higher value of specific heat and result of it the substance require more time to warm up.

Here, the specific heats of these substances are:

Treated glass = 0. 75 J/g • °C

Aluminum = 0. 90 J/g • °C

Stainless steel = 0. 50 J/g • °C

Copper = 0. 39 J/g • °C

In the above data, the value of specific heat of copper is less than other three substances.

Step-by-step explanation:

The equation of the circle in squared form is [tex]\rm (x + 6)^2 + (y + 1)^2 = 38[/tex]. Then the center of the circle is at (-6, -1).

It is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The equation of the circle is given as

[tex]\rm x^{2} + y^2 + 12x +2y - 1 = 0[/tex]

This can be written as

[tex]\rm x^{2} + y^2 + 12x +2y = 1[/tex]

Add both sides 36 and 1, then

[tex]\rm x^{2} + 12x + 36 + y^2 +2y +1 = 1 + 36 + 1[/tex]

Then we know that

[tex]\rm (a+b) ^2 = a^2 + b^2 + 2ab[/tex]

Then

[tex]\rm (x + 6)^2 + (y + 1)^2 = 38[/tex]

Thus, the center of the circle is at (-6, -1).

Step-by-step explanation:

Since the opposite side of the quadarilateral are equal hence it is a rectangle.

The sum of the external side is equal to the perimeter. The perimeter of the shape is expressed as:

P = 2(l+w)

where:

P = 120cm

If the width is 30cm less than twice it’s length, then;

w = 2l + 30

Substitute

120 = 2(l + 2l + 30)
60 = 3l + 30
3l = 30
l = 10

Recall that:

w = 2l + 30
w = 2(10) + 30
w = 50cm

Since the opposite side of the quadarilateral are equal hence it is a rectangle.
