Answer:

27.625

Step-by-step explanation:

28.600

-0.975

_______

27.625

in words... 28.6-0.975. take away 1 from the 6 and make it five, carry it over to the zero in the hundredths place. Make that 10 a 9 and carry it over to the thousandths place and do 10-5 so in the answer, the thousandths place is 5. 9-7 in the hundredths place is 2 so your answer so far is __._25. take 1 away from 8 and that is now 7 so 15-9 is 6. So your answer so far is __.625. 27-0 is 27 so your answer is 27.625.

Simplify each expression by writing the expression without absolute value bars.
sertanlavr [38]

The expression of absolute value |m-11| id m is greater than equal 11 will be equivalent to (m-11).

The general function of absolute value is given as,

                  |a| = { a  ,  if  a≥0     and    -a    , if a<0 }

That is the absolute value will be positive if value of is greater than or equal to 0 and the absolute value will be negative if the value of a is less than 0.

As we have been given the absolute value which is | m – 11|. It can be formed as

             |m-11| = {   (m-11)   ,  if m≥11     and      -(m-11)    ,  if m<11}

So according to the question given the value of m is greater than equal to 11 that is m≥11.

Therefore,  when m≥11 then

                           |m-11| =  (m-11).

Hence if m is greater than equal to 11 then the expression |m-11| will be equivalent to (m-11).

Jim’s sleeping bag is 5 feet long.Jorge’ sleeping bag is 2 yards.Stevens sleeping bag is 68 inches,Whose sleeping bag is longer
Mariulka [41]

Well, we know 1 yard is 3 feet, so 2 yards is 6 feet. That makes Jorge's sleeping bag longer than Jim's. (6 feet is longer than 5 feet)

We also know that 1 yard is 36 inches, so 2 yards is 72 inches. That makes Jorge's sleeping bag longer than Steven's. (72 inches is longer than 68 inches)

Since Jorge's sleeping bag is longer than both Jim's and Steven's, Jorge's sleeping bag is longer.

Write each sum using summation notation<br> 12 + 22 + 32 + 42 + ⋯ + 10000^2
Murljashka [212]

Answer:

50,00,70,000

Step-by-step explanation:

The given sequence is Arithmetic Progression.

Arithmetic Progression is a sequence in which every two neighbor digits have equal distances.

Here first we will find the number of terms

For finding the nth term, we use formula

aₙ = a + (n - 1) d

where, aₙ = value of nth term

a = First term

n = number of term

d = difference

Now, In given sequence: 12, 22, 32, 42, ⋯ , 100002

a = 12, d = 10, n = ? and  aₙ= 100002

∴ 100002  = 12 + (n - 1) × (10)

⇒ 99990 = 10(n - 1)

⇒ n = 10000

Now using the formula of Sum of Arithmetic Sequence,

Sₙ = n÷2[2a + (n - 1)d]

⇒ Sₙ = (10000÷2)[2 × 12 + 9999 × 10]

⇒ Sₙ = 5000 [ 24 + 99990]

⇒ Sₙ = 5000 × 100014 = 50,00,70,000

21. For the following exercises, use the descriptions of each pair of lines given below to find the slopes of Line 1 and Line 2.
dybincka [34]

Answer:

The given lines are perpendicular.

Step-by-step explanation:

In the question, two lines are given as line 1 passes through (1,7) and (5,5). Whereas, line 2 passes through (-1,-3) and (1,1).

It is required to find the slope of given lines and figure out whether they are perpendicular, parallel or neither.

To solve this question, first find the slope of both lines. Check if their product is equal to -1, then they are perpendicular. If the slopes are equal the lines are parallel.

Step 1 of 2

Find the slope of first line.

$$\begin{aligned}m_{1} &=\frac{5-7}{5-1} \\m_{1} &=\frac{-2}{4} \\m_{1} &=-\frac{1}{2}\end{aligned}$$

Step 2 of 2

Find the slope of first line.

$$\begin{aligned}&m_{2}=\frac{1-(-3)}{1-(-1)} \\&m_{2}=\frac{4}{2} \\&m_{2}=2\end{aligned}$$

And

$$\begin{aligned}&m_{1} m_{2}=-\frac{1}{2}(2) \\&m_{1} m_{2}=-1\end{aligned}$$

Since, both slopes are reciprocal of each other.

Therefore, the lines are perpendicular.
