If 3x is the opposite of -5, what is the value of x? -3 5 5/3 -1/15

What is the range for this set of data? 7, 15, 12Mrs. Juarez graded ten English papers and recorded the scores. 92, 95, 100, 62,

Answer:

Following are the solution to the given question:

Step-by-step explanation:

Please find the complete question in the attached file.

Arrange the value into the ascending order:

$62, 88, 89, 90, 92, 95, 96, 98, 100, 100$

Calculating the Range:

$= Greatest - Lowest\\\\= 100 - 62\\\\ = 38$

Outlier = This might be the value "far" from other data values= 62

The range of scores would be, sans outlier,

$88, 89, 90, 92, 95, 96, 98, 100, 100$

Calculating the range without outlier $= 100 - 88 = 12$

Inter Quartile Range $= Q_3 - Q_1$

$IQR = 98 - 89 = 11$

Calculating the IQR without outlier $= 99 - 89.5 = 9.5$

Therefore,

Option a is "True".

Option b is "True".

Option c is "True".

Option d is "False".

Option e is "False".

Option f is "True".

The formula I = PRT is used to calculate the amount of simple Teresa earned. Solve this formula for T

Dmitrij [34]

To solve this formula for T, divide both sides of the original equation by PR:

I PRT

------ = --------- => T = I / (PR)

PR PR

Please note: Because the formula I = PRT involves neither addition nor subtraction, the final formula for T cannot involve either addition nor subtraction. That leaves:

T = I P/R

T= IPR

The second formula here is incorrect; we cannot solve I = PRT for T simply by rearranging the order of the variables. This leaves T = I P/R as a possible answer, but this answer does not agree with my T = I / (PR). Please double check to ensure that you have copied down the four possible answers correctly.

Are the figures below similar? Why or why not? Determine whether the triangles shown in the image are similar.

Vika [28.1K]

Answer:

B) no, because the corresponding angles are not congruent

Step-by-step explanation:

Similar triangles must have proportional sides, as well as congruent corresponding angles. In this instance, we can see that the angles are not congruent, and so there is no need to solve for proportion.

Sarah would like to make a 6 lb nut mixture that is 60% peanuts and 40% almonds. She has several pounds of a mixture that is 80%

weeeeeb [17]

Answer: a. The system that models this situation is,

x + y = 6 , 8 x + 5 y = 36.

b. Solution is x = 2lb and y = 4lb

where x is the quantity of 80% of peanuts mixture mix with y quantity of 50% of peanuts mixture for making 60% of peanuts mixture.

Step-by-step explanation:

Let x quantity of 80% of peanuts mixture mix with y quantity of 50% of peanuts mixture for making 60% of peanuts mixture.

Then According to the question,

x + y = 6 --------- (1)

And, 80 % of x + 50 % of y = 60 % of 6

⇒ 0.8 x + 0.5 y = 3.6

⇒ 8 x + 5 y = 36 --------- (2)

Where equation 1) and equation 2) are the required equation which models the given situation.

Now, 8 × equation 1)

We get, 8 x + 8 y = 48 ----------(3)

equation (3) - equation (2)

we get, 3 y = 12

⇒ y = 4

By putting the value of y in equation (2)

we get, x = 2

Thus, he mixed 2 lb of mixture 80/20 and 4 lb of mixture 50/50 for making 6 lb of 50/50 mixture.

Please help please e

dezoksy [38]

Answer:

a) 4410

b) 4189.5

Step-by-step explanation:

To find the volume of the pool, multiply the length, width, and depth:

21*35*6=4410ft^3

95% capacity would be equal to 0.95*4410=4189.5ft^3
