Sunil need to score 93% on the 6th test to be able to get 90% as the average in her Chemistry class.
What is the average?In Mathematics, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. In statistics, the mean is the average of the given sample or data set. It is equal to the total of observations divided by the number of observations. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.
In this case, let x be the missing value.
Now, we have:
Average = 90%
Total all values = 74% + 92% + 83% + 98% + 100% + x = 447% + x
Number of values = 6
Average = Total all values / Number of values
90% = (447% + x) / 6
447% + x = 540%
x = 540% – 447%
x = 93%
Hence, the missing value is 93%, which means Sunil need to score 93% on the 6th test to be able to get 90% as the average in her Chemistry class.
Although part of your question is missing, you might be referring to this full question: Sunil wants to earn a 90% in her Chemistry class. On the first 5 test, she received a 74%, 92%, 83%, 98%, 100%. What must she score on the 6th test to get the 90% she wants?

In the beginning, there was little or no private ownership. Cucumbers are a pretty interesting example. We had an exchange student who said all the cucumbers were raised on one collective the size of 10 sections. He didn't know how many people were on that farm but it employed many people. The farm was located near a very large city so transportation was not a problem. The state owned the farm.
The second one is a result of the first one. Collectives are not meant to benefit the individual. They benefit everyone.

Parker needs to buy bouquets for table centerpieces. Her client has a budget of $250. If the bouquets cost $14.95 each, which direct variation equation can you use to determine the number of flower bouquets Parker can purchase?
A. x=14.95y
B. y=250x
C.250=14.95x
D. y=250(14.95)
Answer:
C
Step-by-step explanation:
as stated by the questions, the client has a budget of $250, which means we can't exceed $250. This will be our y (dependent variable, as the cost for y depends on how many bouquets we will purchase).
the bouquets cost 14.95 each, so if we have x bouquets , that means that the cost will be 14.95x (independent variable, as this gives the value of y).
therefore, the equation is 250=14.95x, which is C
but let's do process of eliminiation to double check:
if we look at the options, B and D are out (the cost of the bouquets isn't $250 each and also we can't have 250 bouquets , that would be too expensive for the client).
that leaves A and C
A isn't the correct answer. At first glance, it looks like we just switched x and y around. However, it cannot work because x is always the independent variable while y is the dependent variable (the value of y depends on the value of x, while the value of x doesn't depend on y).
Also, there's no mention of the $250 budget in A
by process of elimination and by the explanation above C is the correct answer.
Hope this helps!

5. Find the missing reference angle using arcsin, arccos, or arc tangent. (Round to
the nearest whole number)
14

50
Your answer
Answer:
16°
Step-by-step explanation:
Reference angle = [tex] \theta [/tex]
Side Opposite to reference angle = 14
Adjacent side = 48
Hypotenuse = 50
Let's apply arcsin:
Thus:
[tex] \theta = sin^{-1}(\frac{Opp}{Hyp}) [/tex] (recall: SOHCAHTOA)
Plug in the values
[tex] \theta = sin^{-1}(\frac{14}{50}) [/tex]
[tex] \theta [/tex] = 16.2602047° = 16°
The measure of central angle LOP is °. The length of LP is units. The length of MP is units.
Answer:
2.87units
Step-by-step explanation:
Find the diagram attached
The length of MP can be gotten using the pythagoras theorem
LP² = LM² + MP²
8.5² = 8² + MP²
72.25 = 64 + MP²
MP² = 72.25 - 64
MP² = 8.25
MP = √8.25
MP = 2.87units
Hence the length of MP is 2.87units
The measure of central angle LOP is 180°. The length of LP = 17 units. The length of MP = 15 units.
What is Pythagoras's theorem?Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
The given is given in the question, as shown.
As per the question, we can see that
The measure of central angle LOP is 180°.
LM = 8 units
LP = 2OP
LP = 2(8.5)
LP = 17 units
So the length of LP = 17 units.
As we know that the Pythagorean Theorem,
LP² = LM² + MP²
17² = 8² + MP²
289 = 64 + MP²
MP² = 289 - 64
MP² = 225
MP = 15 units
Thus, the length of MP = 15 units.

Roxanne set a goal o drinking 2.5 liters of water each day.By 10:00 a.M., she drank 3/4 liter, and at lunch she had another 600 ml. In the afternoon. She purchased a ottle of water of water that contained 1.1 liters
Answer:
She has to drink 0.05 liters more
Step-by-step explanation:
She has to drink 2.5 liters of water each day.
The total amount of water she drank is
3/4 liters + 0.6 liters + 1.1 liters + x liters = 2.5 liters
0.75 liters + 0.6 liters + 1.1 liters + x liters = 2.5 liters
2.45 liters + x liters = 2.5 liters
x liters = 2.5 liters - 2.45 liters
x liters = 0.05 liters
She has to drink 0.05 liters more or has not drunk 0.05 liters.
If she drinks 0.05 liters more she will reach her set goal.
3/4 liters
1 liter= 1000ml
3/4 liters= 3* 1000/4 ml
3/4 liters= 3000/4 ml
3/4 liters= 750 ml
750 ml/ 1000ml = 0.75 liters

Step-by-step explanation:
the parallelogram will have equal distances from center to along each diagonal. It is hard to explain with words and not being able to draw it.
So 2a+ 14 = 5a - 4 and a = 2b
solve the frist equation for a then the second equation for b
2a+ 14 = 5a - 4
18 = 3a
6 = a a = 2b 6 = 2b

PT=y,TR=x+3,QT=2y,TS=3x-1 I'm confused and u really need help. My teacher isn't the greatest and wasn't much help.
Answer:
y=10, x=7
Step-by-step explanation:
Since the diagonals of a parallelogram bisect each other, PT should be equal to TR and QT should be equal to TS. So, y=x+3 and 2y=3x-1. Multiplying the first equation by 3 gives you 3y=3x+9. Using elimination to subtract these two equations gives you y=10. And since y=x+3, substitute y=10 there. 10=x+3, x=7.
find the measures of the missing angles in the parallelogram.

The value of the machinery after 5 years is $236.20
Step-by-step explanation:
Generally, we have the depreciation exponential expression as;
V(t) = I (1 - r)^t
V(t) is the value of the machinery at a point in time
I is the initial value or the cost of the machinery when bought which is $400
r is the rate of decrease which is 10% and is same as 10/100 = 0.1
t is the time which is 5 years
Substituting these values;
V(5) = 400( 1 - 0.1)^5
V(5) = 236.196
to the nearest vent, this is $236.20

Molly's family traveled 5/8 of the distance to her uncle's house on Saturday. They traveled 1/3 of the remaining distance on Sunday. What fraction of the total distance to her uncle's house was traveled on Sunday?
Answer: [tex]\dfrac{1}{8}[/tex]
Step-by-step explanation:
Given
On Saturday, Molly's family traveled [tex]\frac{5}{8}[/tex] of the total distance
On Sunday, they traveled one-third of the remaining distance.
Suppose the total distance is x
Distance traveled on Saturday is [tex]\dfrac{5x}{8}[/tex]
Remaining distance is
[tex]x-\dfrac{5x}{8}=\dfrac{3x}{8}[/tex]
On Sunday, they travel
[tex]\dfrac{1}{3}\times \dfrac{3x}{8}=\dfrac{x}{8}[/tex]
fraction of total distance traveled on Sunday is [tex]\dfrac{1}{8}[/tex]
Alfredo tiene 36 cromos más que Iván, y si comprará 10 más , tendría el triple . ¿Cuantos cromos tiene cada uno?
Respuesta:
Alfredo = 59 pegatinas
Ivan = 23 pegatinas
Explicación paso a paso:
Dejar :
Pegatinas de Alfred = a
Pegatinas de Ivan = b
a = b + 36 - - - (1)
a + 10 = 3b- - - (11)
De 1)
a = b + 36
Ponga a = b + 36 en (11)
b + 36 + 10 = 3b
b + 46 = 3b
46 = 3b - b
46 = 2b
b = 23
a = b + 36
a = 23 + 36
a = 59
Alfredo = 59 pegatinas
Ivan = 23 pegatinas
