Answer:

78.5

Step-by-step explanation:

Add the two scores, and then divide this sum by 2 to obtain the average score:

$\frac{100 + 57}{2} = \frac{157}{2} = 78.5$

Answer:

78.5

Step-by-step explanation:

To calculate the average of the assignments, you must find the mean of the assignments.

Mean = sum of the items divided by the number of items

$\frac{100+57}{2}$

$=\frac{157}{2}$

$=78.5$

Pani would pay $59 if she gets a discount of $3 on each shirt and $3 on each jeans

Step-by-step explanation:

Given

Price of shirt = $12

Price of jeans = $19

Price of shirt after $3 discount = 12-3 = $9

Price of jeans after 3 discount = 19-3 = $16

The total money Pani has to pay will be:

$9(3)+16(2)\\=27+32\\=\$59$

Pani would pay $59 if she gets a discount of $3 on each shirt and $3 on each jeans

Given the following information, determine if one of the brands is a better buy. Brand A: 14 ounces for $44. 66 Brand B: 20 ounc

Division is one of the basic mathematical operations. The cost of Brand A and B is the same.

<h3>What is division?</h3>

The division is one of the most basic arithmetic operations. It is used to find the number of times a number is been added to itself.

Given to us

Brand A: 14 ounces for $44.66

Brand B: 20 ounces for $63.80

To compare the two brands we will find the cost of one ounce for each brand.

For Brand A,

The cost of 14 ounces is $44.66, therefore,

$\text{Cost of one ounce} = \dfrac{\$44.66}{14}\\\\\text{Cost of one ounce} = \$3.19$

For Brand B,

The cost of 20 ounces is $63.80, therefore,

$\text{Cost of one ounce} = \dfrac{\$63.80}{20}\\\\\text{Cost of one ounce} = \$3.19$

From the above two values, we can conclude that the cost of Brand A and B is the same.

I don’t really get this question can someone help me out

Inessa [10]

angles EFH and GFH are congruents

for the second equivalence criterion two triangles are equivalents if they have respectively 2 angles and 1 side congruents

the two triangles have congruents the angle right angle (HGF and HEF) and the 55 degrees angles (EFH and GFH); then they have in common the HF side.

so the triangles are congruent and so all the sides are respectively congruent,for example EH with HG:

EH=HG

s+36=7s

s+36-7s=0

s-7s=-36

-6s=-36

6s=36

s=6
