Zielflug [23.3K]
Chrystelle bought 2/3 pound of ham. (given)
She bought 3/5 * 2/3 = 2/5 pound of cheese.

The cheese cost 4.95 per pound, so she paid 2/5*4.95 = 1.98 for the cheese.
The ham cost 5/3 * 4.95 = 8.25 per pound, so she paid 2/3*8.25 = 5.50 for the ham.

Her total purchase was 1.98 +5.50 = 7.48 for the ham and cheese.

Selections B, C, E are correct.

Help me with my math quiz from friday 4/1 <br> SHOW STEPS
malfutka [58]

Hie!! I will be solving the questions in the sequence of the attachments.

_______________________________________

4. As line SU and TV are intersecting each other at O.

A.T.Q, ∠UOV = (7x - 4)°

∠SOT = 87°

Then, ∠UOV = ∠SOT {Vertically Opposite Angles}

\rightarrow\sf{7x - 4=87}

\rightarrow\sf{7x =87+4}

\rightarrow\sf{7x =91}

\rightarrow\sf{x =\frac{91}{7}}

\rightarrow\boxed{\bf{x =13}}

_______________________________________

5. radius = 17ft

circumference of circle = 2πr

\rightarrow\sf{circumference=2\times\frac{22}{7}\times17}

\rightarrow\boxed{\bf{circumference=106.8ft}}

_______________________________________

3. ∠1 and ∠2 - add to 180 (linear pair)

∠1 and ∠3 - equal (Vertically Opposite Angles)

∠3 and ∠4 - add to 180 (linear pair)

∠2 and ∠4 - equal (Vertically Opposite Angles)

_______________________________________

2. 160° + (6x - 16)° = 180° (linear pair)

\rightarrow\sf{6x - 16 = 180-160}

\rightarrow\sf{6x - 16 = 20}

\rightarrow\sf{6x = 20+16}

\rightarrow\sf{6x =36}

\rightarrow\sf{x =\frac{36}{6}}

\rightarrow\boxed{\bf{x =6}}

Determine whether the variable is qualitative or quantitative.Favorite basketball played
wlad13 [49]

Answer:

\text{Qualitative}

Explanation:

Here, we want to get if the given variable is qualitative or quantitative

While qualitative describes the presence of a quality, quantitative speaks about count or number

Thus, what we have here is that we are talking about likeness and not about the count of basketball players. Thus, in this case, a certain basketball player is liked to be called a favorite because of some of the qualities he/she possesses

Thus, we can conclude that the variable is qualitative

The perimeter of a square is 4 times as great as the length of any of its sides. Determine if the perimeter of a square is propo
Angelina_Jolie [31]
The perimiter is 4 times as great as the lenght of any of its sides means that:

4 * a (perimiter) = 4 * a (4 times any of the sides)

It means that one side is 1/4 of the perimeter:

a = 1/4 * 4a
a = a

Answer: Perimeter is proportional to the side length by Perimeter = 4 * Sides or Side = 1/4 Perimeter.
