What kind of number is 92 and why? if you know the others that'd be great!!

Answer:

The correct answer is 113.5

Step-by-step explanation:

33.5+80

Answer:

Angle 1: 34°

Angle 2: 146°

Angle 3: 146°

Angle 4: 34°

Angle 5: 34°

Angle 6: 146°

Angle 7: 146°

Angle 8: 34°

Step-by-step explanation:

Angle 1: because angle 1 and 5 are corresponding, we know that angle 1 is 34°.

Angle 2: because a line is 180°, we can set angle 1 and 2 equal to 180° ( 34+x+15=180) which when solved, x = 131. but you need to plug it back into the equation of angle 2 to find out how many degrees it is. ( 131+15=146 ) So angle 2 is 146°

Angle 3: angles 2 and 3 are vertical angles, so angle 3 is 146°

Angle 4: angles 1 and 4 are vertical, so angle 4 is 146°

Angle 5: is given

Angle 6: angles 2 and 6 are corresponding so they are equal, angle 6 is 146°

Angle 7: angles 6 and 7 are vertical so angle 7 is 146°

Angle 8: angles 5 and 8 are vertical of each other so they are equal, angle 8 is 34°

Step-by-step explanation:

1x2x3=6

Answer:

x = -1

Step-by-step explanation:

Step 1: Write equation

-4(-5x + 2) - 3x - 5 = -30

Step 2: Solve for x

Distribute -4: 20x - 8 - 3x - 5 = -30

Combine like terms: 17x - 13 = -30

Add 13 on both sides: 17x = -17

Divide both sides by 17: x = -1

Answer:

x = -1

Step-by-step explanation:

invere operation

−4(−5x+2)−3x−5= -30

20x - 8 -3x - 5 = -30

17x -13 = -30

17x = -17

x = -1

is this a real question?

Answer:

The rate of survival without brain damage

Step-by-step explanation:

The response variable (or dependent variable) is the variable that is measured and which depends on other variables. In this experiment, the researchers are investigating the impact of reducing body temperature on rate of survival without brain damage. The variable that they were 'measuring' was the rate of survival without brain damage, which depended on the variable of reducing body temperature, therefore the response variable here is the 'rate of survival without brain damage.'

Answer:

length = 10ft

breadth = 5ft

Step-by-step explanation:

Given,

Let breadth be x.

According to the question,

length = 2x

Area = 50ft^2

we know that,

Area of rectangle ( A) = l × b

or, x × 2x = 50 ft^2

or, 2x^2 = 50ft^2

or, x^2 = 50ft^2/2

or, x^2 = 25ft^2

or, x = 5 ft

Now,

2x = 2×5ft =10ft

Therefore, length is 10ft and breadth is 5ft.

Answer: c

Step-by-step explanation:

Answer:

(h°h)(10) = 10

Step-by-step explanation:

(h°h) = 6-(6-x) = x

h(10) = x

x = 10

Answer:

He started climbing 9 feet up into the tree, so we can assume that the initial position is 9ft above the ground.

Then if he wants to get back into the ground, he must "descend" or climb down 9 ft again.

Then the integer is -9 (because he is climbing down now).

In this case, the 0 represents that he does not move.

So the integer 0 is related to: +0ft or -0ft

This means that he climbs up 0ft or down -0ft, which is the same as not moving at all.

Answer:

B) point estimation

Step-by-step explanation:

Sample mean is an example of point estimation. It is a point estimation of the population mean.

A point estimate of a population parameter is defined as one value of a statistic. The sample mean is regarded as the best point estimate of the population mean

Step-by-step explanation:

Divide 3/4 into 2. Got it right on iready

Answer:

[tex]x=\sqrt{3}-2\\x=-\sqrt{3}-2\\x=\frac{1}{2}[/tex]

Step-by-step explanation:

This is a hard one

We have to use the rational root theorem

[tex]2x^3+7x^2-2x-1[/tex] = 0

We have to find all the factors of a and d and put them in a fraction

[tex]a=2\\d=-1\\\frac{1}{1,2}[/tex]

We then plug them into the equation to see if any of them work

The equation isn't true when plugging 1, but is true when plugging in 1/2

factored form of 1/2 is (2x-1)

Then we divide the original equation by (2x-1) (you can use synthetic division or long division, it would be hard to type out the process for that) to get [tex]x^2+4x+1[/tex]

So now the equation is [tex](2x-1)(x^2+4x+1)[/tex]

Solve the second half of this equation using the quadratic formula to get

[tex]\sqrt{3}-2[/tex] and [tex]-\sqrt{3}-2[/tex]

We already know the solution for the first half of the equation (1/2)

So the final answers are:

[tex]x=\sqrt{3}-2, -\sqrt{3}-2, \frac{1}{2}[/tex]

Answer:

8653 × 8975= 77660675.

Step-by-step explanation:

Answer:

It depends on the initial guess Xo

Step-by-step explanation:

The number of iterations required to find the root at r = R  depends on the initial guess Xo, this is because when using Newton's method for finding roots, you will need to pick an initial guess and this will be followed by an iterative process which would converge to a solution. The number of roots before the converging will take place depends on the initial guess Xo made

Answer:

24

Step-by-step explanation:

-12 x -2 = 24

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{24}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{ - 12( - 2)}[/tex]

[tex] \dashrightarrow{ \sf{( - 12) \times ( - 2)}}[/tex]

Multiplying or dividing a negative integer by a negative integer gives a positive integer

i.e ( - ) × ( - ) = ( + )

( - ) ÷ ( - ) = ( + )

[tex] \dashrightarrow{ \boxed{ \sf{24}}}[/tex]

Answer:

21n=

n-number and since its a number (n) and 21 you would put 21n

Answer:

[tex]\boxed {\tt 21n}[/tex]

Step-by-step explanation:

We want to write the product of a number and 21 as an algebraic expression.  Let's define "a number" as the variable n.

We know that "product" means multiplication. The product of a number, n, and 21 is equal to multiplying n and 21.

[tex]n*21[/tex]

21 and n can be flipped due to the commutative property of multiplication.

[tex]21*n[/tex]

[tex]21n[/tex]

The product of a number and 21 is 21n.

Answer:

The value for the original mean = 32

Step-by-step explanation:

Here, we want to calculate the original value of the mean.

Let the number of samples be n

Mathematically;

mean = Total value/n

Now, we added 8 to each of values; total value added = 8 * n = 8n

Now, for the new mean of 40; we have

(Total value + 8n)/n = 40

Total value + 8n = 40n

Total value = 40n -8n

Total value = 32n

kindly recall from the beginning of the solution;

mean = Total value/n

mean = 32n/n

mean = 32

So the original value of the mean is 32
