A deep-sea diver must descend and ascend in short steps to equalize pressure on his body. If the diver rises toward the surface too fast, he may suffer from a physical condition called "the bends." Suppose the diver started at 82 feet below the surface and rose in 5 steps of 15 feet each. Use an integer to describe his new position in relation to the water surface.

Answers

Answer 1

Start by multiplying 15 by 5, and you get 75. then subtract that from 82, and you get 7. Since you are below the surface, the number is negative. So you get -7.

Answer 2

Answer:

-7 feet

Step-by-step explanation:

The total distance the diver rose is 5*15 = 75 feet

If we take the zero at the water surface, then the initial position, that is, 82 feet below the surface has to be considered as -82. The 75 feet risen by the diver is a positive quantity, then his new position, in relation to the water surface, is -82 + 75 = -7 feet, i. e. 7 feet below the surface.

find the missing dimension. base: 27 cm and area: 256.5 cm sq

Answers

What is the figure? A square a triangle ect?

You are trying to find height. I am assuming this is a rectangle you are computing, so I will use

Base • Height = Area

(27) • Height = 256.5 // Plugging in what we know

As per Algebra, you have to be able to manipulate terms in an equation in order to find an answer. In reality, it’s right there, just not in a visible form. To do that, go ahead and divide both sides of the equation by 27; this gets rid of the 27, leaving Height, what we want, alone.

(27/27) • Height = 256.5/27 // Division Property of equality
Height = 9.5 cm

Look at the line plot. The open circle means not 2.5, but everything greater than 2.5. Your answe is going to be the second answer, or "All real numbers greater than 2.5". If the circle was solid the answer would be 1.

On this question it is asked you to describe the solution of an inequality represented by the given graph. First of all you may know that the meaning of the phrases "greater than" and "less than" depends on the direction of the line graphed and the possibles solutions are also associated to whether or not the circle is close or open.

When you look at the line plot you can see, that the point is open meaning that 2.5 is not a possible answer for the equation. Also, the line goes to the right meaning that the values for the possible solutions have to greater than 2.5. In other words the solution for the graphed inequality are the numbers greater than 2.5 but 2.5 is not part of the solution.

The correct answer is all real numbers greater than 2.5.

Factor the expression. d^2-14d+49

Answers

Answer: (d - 7)^2

Procedure to factor:

The expression to factor is a trinomial.

Steps:

1) Probe whether this is a perfect square trinomial, i.e a trinomial that can be factored as (a + b)^2 or (a - b)^2.:

2) Determine if the first and the third terms of the trinomial (once it is ordered, which it is) have exact square roots:

√ (d^2) = d

√49 = 7

3) Since they have exact square roots, test wether the second term of the trinomial equals twice the product of the two square roots determined:

=> 2 * (d) * (7) = 14d which is exactly the second term of the trinomial

4) Now you can write the binomial squared using the sign of the second term. This is:

(d - 7)^2.

You can prove that that is the answer by expanding the binomial squared, which must drive back to the original expression: d^2 - 2(7)(d) + 7^2 = d^2 - 14d + 49.

A study found that 9% of dog owners brush their dogs teeth. Of 578 dog owners, about how many would be expected to brush their dogs teeth? Explain. Please help I am confused

Answers

9 percent of 578 is 52.02.
578/x=100/9
(578/x)*x=(100/9)*x - we multiply both sides of the equation by x
578=11.111111111111*x - we divide both sides of the equation by (11.111111111111) to get x
578/11.111111111111=x
52.02=x
x=52.02

Final answer:

About 52 dog owners would be expected to brush their dog's teeth.

Explanation:

The question is asking to estimate the number of dog owners who brush their dogs' teeth based on the given percentage from a study. To calculate this, you would take the total number of dog owners and multiply it by the percentage that brush their dogs' teeth. In this case, there are 578 dog owners and 9% of them are expected to brush their dogs' teeth.

Here is the calculation:

Number of dog owners who brush their dogs' teeth = Total number of dog owners × Percentage of owners who brush teethNumber of dog owners who brush their dogs' teeth = 578 × 0.09Number of dog owners who brush their dogs' teeth ≈ 52

Therefore, about 52 dog owners out of 578 are expected to brush their dogs' teeth.

A rectangular trampoline measures 15 meters by 18 meters. A pad of constant width is placed around the trampoline so that the total area is 340 square meters. What is the width of the pad? Enter your answer in the box.

Answers

Given is a rectangular trampoline with dimensions 15 meters by 18 meters.

A pad of uniform width is fixed about the boundary of trampoline such that total area becomes 340 square meters.

It says to find width of the pad that is placed around trampoline.

Let's assume the width of pad = 'x' meters.

Now Length of trampoline with pad would be, L = 2x + 15 meters.

And Width of trampoline with pad would be, W = 2x + 18 meters.

Given is the Total area = 340 square meters.

We know the formula for area of rectangle is given as follows :-

Area of Rectangle = Length x Width

⇒ 340 = (2x+15)·(2x+18)

⇒ 340 = 4x² + 66x + 270

⇒ 4x² + 66x + 270 - 340 = 0

⇒ 4x² + 66x - 70 = 0

⇒ 2x² + 33x - 35 = 0

⇒ 2x² + 35x - 2x - 35 = 0

⇒ x·(2x + 35) - 1·(2x + 35) = 0

⇒ (x - 1)·(2x + 35) = 0

⇒ (x - 1) = 0 or (2x + 35) = 0

x can't be negative number, so x = 1.

Hence, x = 1 meter is the width of the pad.

Answer:

The width of the pad is [tex]1\ m[/tex]

Step-by-step explanation:

Let

x----> the width of the pad

we know that

[tex](15+2x)(18+2x)=340[/tex]

Solve for x

[tex]270+30x+36x+4x^{2} =340\\ \\4x^{2}+66x-70=0[/tex]

Solve the quadratic equation by graphing

The solution is [tex]x=1\ m[/tex]

Dilate (9, 6) using a scale factor of 1/3

Answers

The answer is (3,2)

To get this answer we either...
A) Multiply both coordinates by 1/3
or
B) Divide each coordinate by 3

9*(1/3) = 9/3 = 3
6*(1/3) = 6/3 = 2

Final answer:

To dilate the point (9, 6) using a scale factor of 1/3, multiply the x-coordinate and y-coordinate by the scale factor to find the new coordinates which are (3, 2).

Explanation:

To dilate the point (9, 6) using a scale factor of 1/3, we can multiply the x-coordinate and y-coordinate of the point by the scale factor to find the new coordinates.

For the x-coordinate, we have (9) * (1/3) = 3.

For the y-coordinate, we have (6) * (1/3) = 2.

So the dilated point is (3, 2).

Given a circle with measures of (C, d, and r) and a circle with measures of (C', d', and r'), what is r if C C' = 5 and d' = 20?

Answers

Answer:

r = 50

Step-by-step explanation:

We know that:

[tex]\frac{C}{C'}=5[/tex][tex]d'=20[/tex]

So, the ratio between the circumferences is 4 and the diameter of the second circle is 20. In this case, we have to use the ratio between those two circumferences, because that's what is our given data.

[tex]\frac{C}{C'}=\frac{d}{d'}\\5=\frac{d}{20}\\ 100=d[/tex]

From this proportion, we deduct that the diameter of the initial circle is 100. Now, we know that the radius in a circumference is have the diameter. Therefore, the radius is:

[tex]r=\frac{d}{2}=\frac{100}{2}=50[/tex]

Answers

Answer: Width of canvas = 9 inches

Area left for painting after painting the border = 70 square inches.

Explanation :

Since we have given that

Area of painting = 108 square inches

Length of canvas = 12 inches

As we know that

[tex]\text{Area of rectangle} = length\times breadth[/tex]

[tex]108=12\times breadth\\\\\frac{108}{12}=breadth\\\\9=breadth[/tex]

So, breadth of canvas = 9 inches .

Now, Chloe paints a 1 inch wide blue border on the canvas.

[tex]\text{So, remaining length left for painting after painting the border} = 9-1-1=9-2=7\text{ inches}[/tex]

[tex]\text{ Remaining breadth left for painting after painting the border }= 12-1-1=12-2= 10\text{ inches}[/tex]

[tex]\text{So , area of remaining portion }= length\times breadth \\\\ \text{ area of remaining portion }=7\times 10\\\\\text{ area of remaining portion }=70 \text{ square inches}[/tex]

Hence, remaining area = 70 square inches .

Answers

The total purchase price of the watch is: $9,300

$8,000 + (0.06 × $8,000) + (0.10 × 8,000) + $20

$8,000 + $480 + $800 + $20

Answer: Total purchase price of this watch is $9300.

Step-by-step explanation:

Since we have given that

Retail price of watch = $8000

Rate of sales tax = 6%

Amount of sales tax becomes

[tex]\dfrac{6}{100}\times 8000\\\\=\$480[/tex]

Rate of excise tax = 10%

Amount of excise tax is given by

[tex]\dfrac{10}{100}\times 8000\\\\=\$800[/tex]

So, Amount of watch after sales tax becomes

[tex]\$8000+\$480+\$800\\\\=$9280[/tex]

Amount of additional shipping charge = $20

Amount of watch after additional shipping charge becomes

[tex]\$9280+20\\\\=\$9300[/tex]

Hence, Total purchase price of this watch is $9300.
