Answer:

5* 10^(-5)m is the scientific notation of 0.00005m.

Answer:

We have two consecutive even integers:

a and b.

We know that we can write a even integer as:

a = 2*n

where n is an integer.

Then the consecutive integer to a, b, will be:

b = 2*n + 2.

Then the sum of a and b is:

a + b = 2n + 2n + 2 = 4*n + 2 = 2*(2n + 1) = k.

The next two consecutive integers greater than b will be:

c = 2n + 4

d = 2n + 6

then:

c + d = (2n + 4) + (2n + 6) = 4n + 10 = k + 4.

Answer:

c

Answer:

−5m² + 7m + 8

Explanation:

−m² + 6 − 4m² + 7m + 2

= −m² + 6 + −4m² + 7m + 2

[ Combine Like Terms ]

= −m² + 6 + −4m² + 7m + 2

= ( −m² + −4m²) + (7m) + (6 + 2)

= −5m² + 7m + 8

64-10

54

Answer:

Here's how to solve this.

Step-by-step explanation:

a=5 b=5 c=8

so

3*8 + 5*8 - 2*5

Well 3*8=24

5*8= 40

2*5=10

Therefore 24 + 40 - 10.

24 + 40= 64

64 - 10= 54

would be your answer.

Answer:

Cases of congruence of triangles: The two triangles coincide if the length of each side in the first triangle is equal to its counterpart in the second triangle (three sides)...... The two triangles coincide if the lengths of two symmetrical sides are equal, and the two corresponding angles intertwined between these two sides are equal in each triangle. .. Two sides and a bounded angle between them.....

Answer:

see below

Step-by-step explanation:

x - 2/5= 7

Add 2/5 to each side

x - 2/5 + 2/5 = 7+2/5

x = 7 2/5

or if

( x-2) /5 = 7

Multiply each side by 5

(x-2) /5 *5 = 7*5

x-2 = 35

Add 2 to each side

x-2+2 = 35+2

x = 37

Answer:

or

Step-by-step explanation:

x - 2/5= 7

find out what x is

x - 2/5 = 7

x - 2 = 7 (5)

x - 2 = 35

x = 35 + 2

x = 37

--------

or

x - 2/5 = 7

x = 7 + 2/5

Answer: 3266.528

Step-by-step explanation:

The number 531.775197122 is rounded to the nearest ten thousandth place by 531.7752

What is rounding up numbers?

There are basically two rules while rounding up numbers

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

Given data ,

Let the number be = A

Let the rounded number be = B

The value of A is given by

A = 531.775197122

Now , the number A can be rounded of to the nearest ten thousandth place by rounding to the nearest 0.0001 or the Ten Thousandths Place

So , the number will be

The 1 in the ten thousandths place rounds up to 2 because the digit to the right in the hundred thousandths place is 9

When the digit to the right is 5 or greater we round away from 0

Therefore , the number 531.775197122 is rounded to 531.7752

Therefore , the value of B is 531.7752 after rounding up

Hence , The number 531.775197122 is rounded to the nearest ten thousandth place by 531.7752

Step-by-step explanation:

x represents the number of hats.

Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.

Given, Company A sells hats for $11 per hat plus a fixed $7 shipping and handling fee. Company B sells hats for $8 per hat plus a fixed $16 shipping and handling fee.

Let x be the number of hats and y be the total cost for x hats

For Company A:

per hat charges = 11

charge for x hats = 11 * x

Since, shipping charges = 7

Thus,

Total cost for x hats, y = 11x + 7

For Company B:

per hat charges = 8

charge for x hats = 8 * x

Since shipping charges = 16

Thus,

Total cost for x hats, y = 8x + 16

If the Cost is the same,

11x + 7 = 8x + 16

3x = 9

x = 3

therefore, If we order 3 hats then the cost from both companies will be the same. and x represents the number of hats.

Answer:

The 95% confidence interval estimate for the population mean force is (1691, 1755).

Step-by-step explanation:

According to the Central Limit Theorem if we have an unknown population with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from the population with replacement, then the distribution of the sample mean will be approximately normally.

The sample selected here is n = 30.

Thus, the sampling distribution of the sample mean will be normal.

Compute the sample mean and standard deviation as follows:

[tex]\bar x=\frac{1}{n}\sum x=\frac{1}{30}\times 51702=1723.4\\\\s=\sqrt{\frac{1}{n-1}\sum (x-\bar x)^{2}}=\sqrt{\frac{1}{30-1}\times 232561.2}=89.55[/tex]

Construct a 95% confidence interval estimate for the population mean force as follows:

[tex]CI=\bar x\pm z_{\alpha /2}\times\frac{s}{\sqrt{n}}[/tex]

    [tex]=1723.4\pm 1.96\times\frac{89.55}{\sqrt{30}}\\\\=1723.4\pm 32.045\\\\=(1691.355, 1755.445)\\\\\approx (1691, 1755)[/tex]

Thus, the 95% confidence interval estimate for the population mean force is (1691, 1755).
