Answer 1

If you add 8x and 14x it will give you 22x

If you subtract 11-1 you have 10.

so the answer is 22x -10

Answer 2

[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]

Find the measure of JL.

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

Given, K is the midpoint of JL. So, JK = KL.

KL = 14x - 1JK = 8x + 11JL = ?

________

JL = JK + KL (given that K is the midpoint of JL)

JL = (8x + 11) + (14x - 1)

________

[tex] \large \boxed{\mathfrak{Steps} \downarrow}[/tex]

[tex] \sf( 8 x + 11 ) + ( 14 x - 1 )[/tex]

Combine 8x and 14x to get 22x.

[tex] \sf \: 22x+11-1 [/tex]

Subtract 1 from 11 to get 10.

[tex] \boxed{ \boxed{ \bf22x+10 }}[/tex]

________

Also given that, JK = KL.

So, (8x + 11) = (14x - 1)

⇨ (8x + 11) = (14x - 1)

⇨ 8x + 11 = 14x - 1

⇨ 11 + 1 = 14x - 8x

⇨ 12 = 6x

⇨ x = 12 / 6

⇨ [tex] \boxed{ \boxed{ \bf \: x= 2 }}[/tex]

________

Now, value of JL will be,

JL = 22x + 10

Substitute the value of x.

JL = 22(2) + 10

JL = 44 + 10

[tex] \boxed{ \boxed{ \bf\: JL = 50 }}[/tex]

⇨ So, the value of JL will be 50 units.

The beginning mean wage in a certain Industry is $70,480.00. If the mean wage grows by 4.125%, what is the new mean wage? (2 points)
O $67,572.70
O $73,387.30
O $75,567.98
O $77,456.90

Answers

The new wage is $73,387.30

What is a percentage?

A percentage can be defined as a ratio or number expressed as a fraction of hundred ( 100).

From the information given, we have;

Initial mean wage is $70,480.00The wage grows by 4.125%

To determine the new age, we need to multiply the initial mean wage by the percentage of increase, we have;

= $70,480.00 × 4. 125 / 100

Multiply through

= $ 290, 730/ 100

= $ 2, 907. 3

The new wage = $70,480.00 + $ 2, 907. 3

The new wage = $73,387.30

Thus, the new wage is $73,387.30

What is the approximate value of this square root? ✓139 Enter your answer, rounded to the nearest tenth, in the box.

Answers

Answer:

The square root of 139 is expressed as √139 in the radical form and as (139)½ or (139)0.5 in the exponent form. The square root of 139 rounded up to 6 decimal places is 11.789826.

Step-by-step explanation:

The rounding off ✓139 to the nearest tenth will be 11.79

What is rounding off ?

Rounding off means a number is made into simpler form by keeping its value fixed but closer to the next number.

To round off the number to the nearest tenth we need to look at the hundredths place digit. If the digit is 1, 2, 3, 4 then we don't have to do anything, if the digit is 5, 6, 7, 8, 9 we must round up.

here, The value of number ✓139 is 11.7898 and value at tenth place is 8 so round up the hundredths place digit, hence the rounded off to the nearest tenth will be 11.79

Therefore, the rounding off ✓139 to the nearest tenth will be 11.79

stone have fallen after 10 seconds?
A.35
B.29
C.21
D.32

Answers

Answer:

Step-by-step explanation:

The stone have fallen 29 meter after 10 seconds.

We have,

a₁= 2

a₅₀= 149

a₁₀ = ?

Now, using the formula

aₙ = a₁ + (n-1)d

So, 149 = 2 + (50-1)d

149 - 2 = 49d

147 = 49d

147/49= d

d= 3

Now, the stone would fall after 10 second is

=2 +(10-1)3

= 2 + 9(3)

= 2+ 27

= 29 m

The sum of three consecutive odd integers is 75. Find the integers.

Answers

Answer:

23, 25, and 27.

Step-by-step explanation:

Let the first odd integer be k.

Since the three numbers are consecutive odd integers, the second is given by (k + 2) and the third by (k + 4).

Their sum is 75. Hence:

[tex]k + (k + 2) + (k + 4) = 75[/tex]

Solve for k. Combine like terms:

[tex]3k + 6 = 75[/tex]

Subtract:

[tex]3k = 69[/tex]

And divide:

[tex]k = 23[/tex]

Therefore, the first number is 23.

In conclusion, the three consecutive, odd integers are 23, 25, and 27.

All the three integers are, 23, 25, 27

We have to given that,

The sum of three consecutive odd integers is 75.

Now, Let the first odd integer be x.

Since, the three numbers are consecutive odd integers,

Hence, the second is, (x + 2) and the third is, (x + 4).

Here, The sum of three consecutive odd integers is 75.

Hence, We get;

x + (x + 2) + (x + 4) = 75

3x + 6 = 75

3x = 75 - 6

3x = 69

x = 69/3

x = 23

Thus, All the three integers are,

x = 23

x + 2 = 23 + 2 = 25

x + 4 = 23 + 4 = 27
