option D

Step-by-step explanation:

the correct answer is option D

A precise measurement is one in which we can measure the smallest of the value.

In 17.775 we can measure the smallest value of 0.001

In 18.55 we can measure smallest value up to 0.01

In 17.5 we can measure smallest value up to 0.1

In 18 we can measure smallest value of 1.

hence, the correct answer will be option D which will be 17.775 in which we can measure 0.001 value.

Find the length of diagonal XU in the hexagon below. Round your solution to 2 decimal points

SpyIntel [72]

Answer:

The length of diagonal XU is 6.40 units

Step-by-step explanation:

* Lets explain how to find the distance between two points

- The rule of the distance between two points $(x_{1},y_{1})$

and $(x_{2},y_{2})$ is:

$d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

* Lets solve the problem

-From the attached figure:

- The coordinates of the vertex X are (2 , 2)

- The coordinates of the vertex U are (-2 , 7)

∴ The point $(x_{1},y_{1})$ = (2 , 2)

∴ The point $(x_{2},y_{2})$ = (-2 , 7)

∴ $x_{1}=2,x_{2}=-2$

∴ $y_{1}=2,y_{2}=7$

∵ $d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

∴ $d=\sqrt{(-2-2)^{2}+(7-2)^{2}}=\sqrt{(-4)^{2}+(5)^{2}}=\sqrt{16+25}=\sqrt{41}$

∵ $\sqrt{41}=6.403124$

∴ d = 6.40

* The length of diagonal XU is 6.40 units

You purchase a laptop for $399.99, a carrying case for $24.99 and some cleaner for $5.00. The sales tax rate on your purchase is

Lynna [10]

Answer:

$461.15

Step-by-step explanation:

Total amount of items:

Add all the prices together

399.99+24.99+5=429.98

Sales tax:

Convert 7.25% to a decimal

7.25/100=0.0725

Multiply the total by the decimal

429.98*0.0725=31.17355

Final cost:

Add the sales tax and total amount

429.98+31.17355=461.15355

Round to the nearest cent/hundreth

$461.15

Hope this helps! :)

Members of a lacrosse team raised $2331.50 to go to a tournament. They rented a bus for $1224.50 and budgeted $61.50 per player

LiRa [457]

Answer: x=18

Step-by-step explanation:Based on the given conditions, formulate: 122.5+61.5 times x =2331.5

Rearrange unknown terms to the left side of the equation:

Calculate the sum or difference:61.5x=1107

Divide both sides of the equation by the coefficient of variable: x=1107 divided by 61.5

Calculate the product or quotient:x=18

get the result:x=18
