89. 70 is what percent of 350?​

Answer:

4/10

Step-by-step explanation:

Answer:

No, it will not be a right triangle

Step-by-step explanation:

Since E (-4, 5) and F (-1, 1) are both in-plane one and G (3, 4) in-plane two

The x's are wrong for E and F which would be a cause for not a right triangle

And the y for G is not either 5 or 1 which would help make the triangle a right triangle.

So the triangle ends up being an scalene triangle and not a right triangle

1.  solid and liquid

2. Evaporation changes liquid water to water vapour.

for #1: for example, it's raining, when it rains, the rain is water (liquid).

Or it's snowing, the snow is solid.

for #2: for example, when you are making tea, you need hot water, so you add heat, then the water lessens because it's transforming to gas, and sometimes you can see it.

Answer:

1. solid and liquid

2. water vapor (gas)

The term (xy)^7 means (xy) is a factor 7 times:

The commutative and associative properties of multiplication let us rearrange this to ...

  = (x·x·x·x·x·x·x)·(y·y·y·y·y·y·y)

  = (x^7)(y^7)

Under the assumption of uniform iron beam and definition of uniform density, the total mass of the iron beam is equal to 81931.2 grams.

Let suppose that the iron beam has an uniform density, the mass of the iron beam (m), in gram, is equal to the product of its density (ρ), in grams per cubic centimeter, and its volume (V), in cubic centimeters:

m = ρ · V     (1)

If we know that ρ = 10504 cm³ and V = 7.8 g/cm³, then the mass of the iron beam is:

m = (7.8 g/cm³) · (10504 cm³)

m = 81931.2 g

Under the assumption of uniform iron beam and definition of uniform density, the total mass of the iron beam is equal to 81931.2 grams.

Answer to 1:

[tex]\frac{x^3}{2y^25}[/tex]

First thing you want to do is combine like terms on the bottom. Since it's multiplication, all you have to do is add the exponents. So for x you'd get x raised to the -9 power and for y you'd get 2y raised to the power of 7

Second thing is the numerator of the fraction. Since this is raising what is inside the paranthesis to a power, you must multiply this power by the powers of x and y, respectively. You should get x raised to the power of -6 and y raised to the power of -18

Here's where it gets complicated. to rationalize the problem, you must add parts from the numerator and denominator or vice versa. You cannot have any negative exponents anywhere in the fraction.  So that means for x you have to add 9 to the x on the top to cancel out the -6 and rationalize the remaining x's. You should end up with x^3.

For y, you work the opposite way. Since the negatives are only on the top, you simply add 18 to the bottom y's and it remains rationalized.

If done correctly this should come out to x^3/2y^25

Answer to 2:

(x^20y^12)/256

First thing you can do on this one is to cancel out the x^0s. Anything to the power of 0 equals one so only the coefficients will remain. Multiply those together and you'll get 4.

Next you will rationalize the ys. Add the bottom 3 to the top to cancel out the denominator and you're left with y^-3. Leave it like this for now.

Now is the difficult part. You must take everything that is inside the parenthesis to the power of -4. That includes the coefficients and the exponents. 4^-4 = 1/256. This means that you now must move the coefficients to the bottom. You should currently have y^-3/(256x^5).

Now take the exponents to the power using the same rules as question 1. -3*-4 = 12 and 5*-4 = -20. You should now have y^12/(256x^-20)

Lastly, we must rationalize the denominator. To do so, move the x^-20 to the numerator and make the exponent positive. After doing this, you have the answer: (x^20y^12)/256

Answer:

C is 17.

Use Pythagorean theorem to find c (hypotenuse)

[We can use this theorem because it is a right triangle]

a^2 + b^2 = c^2

8^2 + 15^2 = c^2

c^2 = 289

c = sqrt(289) = 17

Answer: c = 17 cm

Step-by-step explanation:

     Since this is a right triangle, we will use the Pythagorean theorem to solve. The a and b variables are legs, the c variable is the hypotenuse. Here, we are solving for the hypotenuse.

a² + b² = c²

8² + 15² = c²

64 + 225 = c²

64 + 225 = c²

289 = c²

c = [tex]\sqrt{289}[/tex]

c = 17

           Side c has a length of 17 cm.

Answer: 10:58 a.m.

Step-by-step explanation:

To solve this problem, find how many hours will pass in the given timeframe. From this Monday to next Monday, a week will pass. A week is equal to 7 days. A day has 24 hours, so multiply 7 days by 24 hours. 7*24 = 168 hours.

Since the watch gains 10 seconds every hour, multiply 168 hours by 10 seconds. This means your watch will gain 1680 seconds over the week.

To find what time the watch will be at, first find how many minutes will pass. There are 60 seconds in a minute, so divide 1680 seconds by 60 seconds. 1680/60 = 28.

Add 28 minutes to 10:30 a.m. to get a final time of 10:58 a.m.

Answer: y=-1x+5

Step-by-step explanation:

1. Use slope-intercept formula (y = mx + b) to find the slope which is represented by the variable 'b'.

m = ∆y / ∆x

m = -1 / 1

m = -1

y= -1x + b

2. Use any cooresponding x and y values to substitute into the formula. Ex: (x,y) → (1,4)

y = mx + b

4 = -1(1) + b

4 = -1 + b

5 = b

3. Plug in the values found into the formula.

y = -1x + 5

Answer:

1/6

Step-by-step explanation:

Firstly the coin will have a probability of getting 1/2 for tails and also 1/2 for heads since it is fair.

A cube has 6 sides hence will have numbers 1-6 on each side. Numbers greater than 4 on a cube will be 5,6 and both of them have a 1/6 chance of getting drawn therefore in total it is a 2/6 chance.

Probability of getting tails is 1/2 and probability of getting number greater than 4 is 2/6.

Hence the total probability will be 1/2 x 2/6 = 1/6

Additional comment

Linear and quadratic equations are specific cases of polynomial equations, which involve sums of powers of the variables. The highest power involved is the degree of the equation: 1 for linear, 2 for quadratic.

  f(x) = x +2 . . . . has x to degree 1, so is a linear equation

  f(x) = 3x^2 -5 . . . . has x to degree 2, so is a quadratic equation

  f(x) = √(x -6) . . . . is "none of these"

(This is another vocabulary question. Linear, quadratic, exponential, degree, term, polynomial, ... are all words with specific definitions related to algebraic functions.)

The correct roots of this equation is:

x = 10

y = 6

– This equation is a value substitution system. To solve it, we will: add the terms equal to x, with the sums of the equality.

2x + y = 26

x - y = 4

2x + x = 26 + 4

3x = 30

x = 30/3

x = 10

– Now, let's "take" the first equation of the system, and we'll calculate it, replacing x with its value.

2x + y = 26

2 . 10 + y = 26

20 + y = 26

y = 26 - 20

y = 6

Therefore, the roots of this equation or system is:

x = 10

y = 6
