Answer:
it's -10
Step-by-step explanation:
because in the question they says below the surface of the water
so I think it's right
The upward is taken as positive and the downward is taken as negative. Then the integer can be represented as negative 10.
What is a sign convention?Sign convention means the rule that is used when the sign is to be changed. It is applicable only when the equation is considered.
You dive 10 feet below the surface of the water.
Then the negative sign should be used because we considered the right side as positive and the left side as negative similarly upward is taken as positive and downward is taken as negative.
Then the integer can be represented as negative 10.

Factor the trinomial. Factor out the GCF first.
5h^2k^2 – 15hk^3 – 200k^4
Answer:
The factored form is: [tex]5k^2(h^2 - 3hk - 40k^2)[/tex]
Step-by-step explanation:
The factorization of the trinomial is given by the multiplication of the greatest common factor of each coefficient(numeric, h and k), put it in front, and divide each term by it.
Numeric:
GCF between 5, 15 and 200.
We keep dividing while all factors can be divided by the same number
5 - 15 - 200|5
1 - 3 - 40
No other possible division, so the numeric GCF is 5.
Coefficient h
To the 2, to the 1, and does not appear(to the 0). So the GCF is 0.
Coefficient k
2, 3 and 4. The GCF is 2.
So
[tex]5k^2(\frac{5h^2k^2}{5k^2} - \frac{15hk^3}{5k^2} - \frac{200k^4}{5k^2}) = 5k^2(h^2 - 3hk - 40k^2)[/tex]
The factored form is: [tex]5k^2(h^2 - 3hk - 40k^2)[/tex]

Step-by-step explanation:
Let the number be x
140% of x = 39

Find the lengths of the missing sides in the pairs of similar triangles
Answer:
x = 4
Step-by-step explanation:
The inner and outer triangles are similar, thus the ratios of corresponding sides are equal, that is
[tex]\frac{x}{5}[/tex] = [tex]\frac{8}{10}[/tex] ( cross- multiply )
10x = 40 ( divide both sides by 10 )
x = 4

Answer:
x=17
Step-by-step explanation:
The exterior angle theorem states that one exterior angle of a triangle is equal to the sum of its opposite interior angles. Knowing this, we can set up the following equation:
(8x-11)=(5x)+(2x+6)
Open up the parentheses
8x-11=5x+2x+6
8x-11=7x+6
Add 11 to both sides
8x-11+11=7x+6+11
8x=7x+17
Subtract both sides by 7x
8x-7x=7x+17-7x
x=17
I hope this helps!

The product of a number and 2 is 3 less than the quotient of a number and 5 .
Answer:
The sentence you have can be expressed in algebra (using x as 'the number'):
2x + 5 = x / 3. (We add 5 to the left side because that product is less than the right side.)
Now all you have to do is to combine the x terms on one side of equation, putting the constant on the other side of the equation, and solve for x.
or
Let the unknown number that we are solving for be x.
The product of a number and 2 means 2*x
5 less than the quotient of a number and 3 means x/3 - 5.
So,
2*x = x/3 - 5 subtract x/3 from both sides of the equation
2x - x/3 = -5 , now find the least common denominator for the left side of the equation
6x/3 - x/3 = -5
(6x - x)/3 = -5
5x/3 = -5, now multiply both sides of the equation by 3
5x = -15 now divide both sides of the equation by 5
x = - 3. So the number is -3.
Step-by-step explanation:
Building an equation and solving for the number, it is found that the number is [tex]x = -\frac{3}{2}[/tex]
----------------------
The number can be called x.Product of a number and 2 is [tex]2x[/tex]3 less than the quotient of a number and 5 is: [tex]\frac{x}{5} - 3[/tex]Equal, thus:
[tex]2x = \frac{x}{5} - 3[/tex]
Multiplying everything by 5:
[tex]10x = x - 15[/tex]
[tex]9x = -15[/tex]
[tex]x = -\frac{15}{9}[/tex]
[tex]x = -\frac{3}{2}[/tex]

In a sample of 528 customers, 237 say they are happy with the service. If you select three customers without replacement for a commercial, what is the probability they will all say they are happy with the service
Answer: 0.0898
Step-by-step explanation:
Probability = [tex]\dfrac{favorable\ outcomes}{Total\ outcomes}[/tex]
Given : Sample size : 528
Number pf customers say they are happy = 237
Probability of getting one happy customer= [tex]\dfrac{237}{528}[/tex]
Probability of getting second happy customer= [tex]\dfrac{236}{527}[/tex] [subtract 1 from both numbers]
Probability of getting third happy customer= [tex]\dfrac{235}{526}[/tex]
If 3 customers are elected without replacement
The probability they will all say they are happy with the service = [tex]\dfrac{237}{528}\times\dfrac{236}{527}\times\dfrac{235}{526}[/tex]
[tex]\approx0.0898[/tex]
Hence, the required probability = 0.0898

B. Ramp with a length of 200 feet and a height of 50 feet.
Step-by-step explanation:
When it comes to slope, y is on top and x is on the bottom. The fraction gives us a ratio. In this case, the x is 4 times bigger than the y. In this instance, the length of the ramp is 4 times bigger than the height of the ramp.
You check by seeing if they reduce to 1/4:
50/200 = 1/4
