Answer:

x = 11.2 mi

Step-by-step explanation:

[tex]c^{2} = a^{2} + b^{2}\\(14.4)^{2} = (9)^{2} + b^{2}\\207.36 - 81 = b^{2} \\126.36 = b^{2}\\\sqrt{126.36} = b\\b = 11.2[/tex]

Alex's expanded form for the number 165.038 is not correct. The correct expanded form for the number 165.038 is 100 + 60 + 5 + 0.03 + 0.008.

The number 165.038 can be broken down into its individual place values:

Hundreds: 100

Tens: 60 (6 tens)

Ones: 5

Tenths: 0.03 (3 hundredths)

Hundredths: 0.008 (8 thousandths)

So, the correct expanded form for the number 165.038 is:

100 + 60 + 5 + 0.03 + 0.008

Hence, Alex's expanded form for the number 165.038 is incorrect. The correct expanded form is: 100 + 60 + 5 + 0.03 + 0.008.

Answer:

By the way that the line is facing.

Answer:  220

Step-by-step explanation:

A- 22.50 x 12 = 270

B- 12.50 x 12 = 150

C- 270 + 150 - 200 = 220

ANSWER- 220

Answer:

A :-) Given -

perimeter = 65 inches

Side ‘a’ = 2x

Side ‘b’ = 3 1 by 4x + 1

Solution -

Perimeter = 65

= a + b = 65

= 2x + 3 1 by 4x + 1 = 65

( 3 1 by 4 = 4 x 3 + 1 = 12 + 1 by 4

= 13 by 4 )

= 2x + 13 by 4x + 1 = 65

= 2x + 13 by 4x = 65 - 1

= 2x + 13 by 4x = 64

= 15 by 4 x = 64

= x = 64 x 4 by 15

= x = 256 by 15

= x = 17.06

.:. The value of x = 17.06.

Answer:

y = T(x) = 8 + (9/shirt)x

Step-by-step explanation:

Represent "total amount" by T(x).  Then:

y = T(x) = 8 + (9/shirt)x

Here the shipping cost ($8) is a fixed cost and the cost of the x shirts is ($9/shirt)(x), where x is the number of shirts bought.

Note that this is a linear equation, and that 8 represents the vertical intercept and (9/shirt) the slope of the line representing the total cost.

The equation that shows the relationship between the number of T-shirts Manuel buys, x, and the total amount he will pay, y is y = 9x + 8.

The total amount Manuel will pay consists of the cost of the T-shirts and the shipping cost.

The cost of the T-shirts is $9 each, and the shipping cost is a flat $8.

The equation that shows the relationship between the number of T-shirts Manuel buys (x) and the total amount he will pay (y) can be written as y = 9x + 8.

Hence, y = 9x + 8 is the equation that shows the relationship between the number of T-shirts Manuel buys, x, and the total amount he will pay, y.

(384.1 miles)/(14.2 gallons) = (384.1)/(14.2) mpg = 27.049 mpg approximately

mpg = miles per gallon

Answer:

27.05 miles per gallon

Step-by-step explanation:

384.1 miles = 14.2 gallons

x = 1 gallon

14.2x = 384.1

x = 384.1/14.2

Step-by-step explanation:

Men=5

Women=3

Available Strength:

Men=7

Women=6

Objective:Finding no of such committees where particular 2 women are never together.

So initially ,Total possible number of commitee=7c5×6c3=420.

Now we need to find total committes where two particular women say(Sita and Gita ) are never together.

Approach—->

As the commitee requires 5 men and 3 women.

Let us first find number of committees where Sita and Gita are always together.

Hence we reserve 2 women seats for them.

Now we need one women out of remaining 4 women.

So possible number of such commitees 7c5×4c1.

=84.

Hence number of committees where Sita and Gita are never together

=420–84

=336.

1. 3n - 5

Five less = -5

Than thrice (three times) a number = 3n

2. 7n + 3

The product of 7 and a number = 7n

Added to 3 = + 3

3. 1/2(3n - 4)

One-half = 1/2

The difference of thrice a number and 4 = 3n - 4

Answer:

y = 20x + 0.15s

Step-by-step explanation:

Shew makes $20 par hour, so for x hours, she makes 20x.

She makes 15% commission on the sales, s. 15% = 0.15,so for the sales, s, she makes 15% * s = 0.15s.

The total she makes is 20x + 0.15s

Answer: y = 20x + 0.15s

The equation in the form y = mx + cs models Emma’s situation is

y = 20x + 0.15s

Shew makes $20 par hour, so for x hours, she makes 20x.

The slope-intercept of the line y= mx+c

Where y co-ordinate

x-  x co-ordinate

m=slope of the given line

C-y intercept.

She makes 15% commission on the sales, s. 15% = 0.15,

So for the sales, she makes

15% * s = 0.15s.

The total she makes is 20x + 0.15s
