If Carrie has a string 9 inches long, what she will cut the piece into is mathematically given as

X=2.25pcs

<h3>What is the number of pieces?</h3>

Generally, the equation for the number of pieces is mathematically given as

X=Total number *ratio

Therefore

X=9*1/4

X=2.25

In conclusion, If Carrie has a string 9 inches long, she will get 2.25 pics at a 1/4 ratio

The difference between the lengths of a paddle boat and a pier is -6 1/2 feet. The pier is 15 3/4 feet long. How long is the pad

dmitriy555 [2]

Answer:Length of paddle boat=9 1/4

Step-by-step explanation:

Difference between lengths of a paddle boat and a pier i= -6 1/2 feet

Length of pier=15 3/4

Length of paddle boat=??

Length of paddle boat- Length of pier=-6 1/2

Length of paddle boat = -6 1/2 + 15 3/4

( Add whole numbers to whole numbers and fraction to fraction)

=9 -2+3 /4

=9 1/4

A copy machine can print 480 copies every 4 minutes. How many copies can it print in 10 minutes?

Irina-Kira [14]

Step-by-step explanation:

So you need to figure out how much it can print in 1 minute. You can find that out by dividing 480 by 4. You get 120 which you then multiple by 10.

So the answer is 1,200

Which correctly describes a cross section of the cube below? Check all that apply.

yarga [219]

A cross section parallel to the base is a square measuring 4 cm by 4 cm 

Step-by-step explanation:

Here we have to select the correct statement regarding a cross section of the cube :

A cross section parallel to the base is a square measuring 4 cm by 4 cm :

Since , every side of a cube is same . Any cross section of a cube must be parallel to a square base . Hence, correct statement .

A cross section parallel to the base is a rectangle measuring 4 cm by greater than 4 cm :

Since , every side of a cube is same . Any cross section of a cube must be parallel to a square base . Here, base is rectangle . We don't have a rectangle base in cube . Not correct statement.

A cross section perpendicular to the base through the midpoints of opposite sides is a rectangle measuring 2 cm by 4 cm:

Since , every side of a cube is same . Any cross section of a cube must be parallel to a square base . Here, base should be square not rectangle . So , Not correct statement.

Using the Law of Cosines, in triangle DEF, if e=18yd, d=10yd, f=22yd, find measurement of angle D

Ivahew [28]

Check the picture below.

$\bf \textit{Law of Cosines}\\ \quad \\
c^2 = {{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)\implies 
c = \sqrt{{{ a}}^2+{{ b}}^2-(2{{ a}}{{ b}})cos(C)}
\\\\\\
\cfrac{{{ a}}^2+{{ b}}^2-c^2}{2{{ a}}{{ b}}}=cos(C)\implies cos^{-1}\left(\cfrac{{{ a}}^2+{{ b}}^2-c^2}{2{{ a}}{{ b}}}\right)=\measuredangle C\\\\
-------------------------------\\\\
\begin{cases}
d=10\\
e=18\\
f=22
\end{cases}\implies cos^{-1}\left(\cfrac{{{ 18}}^2+{{ 22}}^2-10^2}{2(18)(22)}\right)=\measuredangle D$

$\bf \implies cos^{-1}\left(0.893\overline{93}\right)=\measuredangle D\implies 26.63^o\approx \measuredangle D$
