A.1 over 20

B.3 over 64

C.7 over 16

D.9 over 16

Answers

Answer 1

Answer: oranges+apples+pears = 4+9+3=16

oranges = 4/16
pears = 3/16
4/16 + 3/16 = 7/16

Two ways you can evaluate 15(90-3)

Answers

15 of 90 minis 3 15 times 90 minus 3

15(90-3)
first way
15 times 90 = 135
15 times 3 = 45
135 - 45 = 90
second way
90-3 = 87
15(87) = 1305

What is the advantage of using a bar graph over a pie chart?

Answers

Answer a bar chart can be used for a broader range of data types, not just for breaking down a whole into components.

Step-by-step explanation:

Final answer:

Bar graphs are advantageous over pie charts mainly because of their precision, scalability, and flexibility in data representation. They allow for clearer comparisons among different data categories, precise measurement of values, and flexibility in the choice of what is represented on the axes.

Explanation:

The advantage of using a bar graph over a pie chart revolves around the precision and scalability of data representation. In a bar graph, you can easily compare different data categories, make precise measurements of the values represented, and adjust the vertical axis to emphasize differences in quantities.

For instances with many small slices and one large one, a pie chart can create bias perceptions of the size distribution because the categorization of the slices can make some appear bigger than others. However, bar graphs can clearly represent data regardless of how many categories there are because each data point is displayed as an independent bar.

A bar graph is also more flexible in representing multiple data categories and longitudinal data since it can display both categorical and numerical values on its axes. For example, bars can represent countries or years, and the vertical axis can represent a numerical or a percentage value.

The circle graph shows the location of Oklahoma’s 77 counties in the state. Which three regions combined have 1/2 of the counties?
A.Northwest, Southwest, Southeast

B.Southwest, Northeast, Northwest

C.Northeast, Southwest, Tulsa Metro

D.Southeast, Northeast, Oklahoma City Metro

Answers

C) because if you add up percents, it adds to 50%, or 0.5 or 1/2:
Northeast 23%, Southwest 21%, Tulsa Metro 6%
23 + 21 + 6 = 50

C. Northeast, southeast,Tulsa metrois your answer

Solve the equation: 7x = 42.
A. x = – 7
B. x = – 6
C. x = 6
D. x = 7

Answers

7x=42
Divide both sides by 7
42÷7 =6
6 x 7 = 42
C. x = 6

7x = 42

7x/7 = 42/7
x = 42/7
x = 6

Answer: x = 6

A social worker earns $760 gross pay. If he is married and claims 1 dependent, his state tax rate is 7%, and FICA is 7.65%, what is his net
pay?

Answers

I believe the net pay is $648.66.
$760×.07 for sales tax rate =53.20
$760×0.0765 for FICA= 58.14
(7.65÷100=0.0765)
now 760-53.20-58.14= 648.66

Triangles L O N and L M N share common side L N. Angles O L N and N L M are congruent. What additional information would be needed to prove that the triangles are congruent using the ASA congruence theorem? ON ≅ MN ∠LON ≅ ∠LMN LN ≅ NM ∠LNO ≅ ∠LNM

Answers

The additional information required to prove that the triangles are congruent using the ASAcongruence theorem is; ∠LNO ≅ ∠LNM

We are given that;

△LON and △LMN share a common side LN.

This means that for both triangles LN = LN by reflexive property as LN is congruent to itself.

Secondly, we are told that;

∠OLN and ∠NLM are congruent.

We can see that L is an included angle of the congruent side LN.

Now, ASA congruency means Angle - Side - Angle. That means two congruent angles and the included side.

Thus, we need one more angle of the included side LN.

We already have for L, and so the remaining angles that will make△LON and △LMN congruent are;∠LNO and ∠LNM.

Answer:

The answer is " $\bold{\Delta LNO \cong \Delta LMN \ if\ \angle LNO = \angle LNM}$ "

Step-by-step explanation:

Two angles will be congruent to each other in order to show ASA congruence between all the triangles. Its angle $\angle LNO \cong \angle LNM$ is a common angle in both triangles As a result, we'll use the ASA congruence law to show that perhaps the triangles are congruent.

$In\ \Delta LON \ and \ \Delta LMN \n\n Side\ \ ON \cong Side\ \ MN \n\n\angle LNO \cong \angle LNM ( \because common ) \n\n \angle LON \cong \angle LMN (\because Given ) \n\n\to \Delta LON \cong \Delta LMN \text{( through the ASA congruence theorem)}\n$
