rewrite the fraction as a decimal 69/4
Answer:
17.25
Step-by-step explanation:
69 ÷ 4 = 17.25I hope this helps!
The solution is: the fraction 69/4 as a decimal is 17.25.
we have,
the fraction is 69/4
now, we get,
69 ÷ 4 = 17.25
i.e. we get,
we have to find how many times 4 would go into 69 by dividing
The quotient is 17 and 4 x 17= 68
Left is 1 which still has to be divided by 4 1/4= 0.25
so, we get,
17+0.25
=17.25
Hence, The solution is: the fraction 69/4 as a decimal is 17.25.

Sending text messages from Katrina's cell phone costs $0.18 per text message . From last monthshe has a credit on her bil for $9.00How much more money will she need to pay for text messages this month if she has sent 204 messages?
A. $ 29.22
B. $25.72
C.$36.72
D. $27.72
Answer:
D. $27.72
Step-by-step explanation:
Calculation for How much more money will she need to pay for text messages
First step is to the Total cost of sending 204 messages
Total cost=204 messages* $0.18 per text message
Total cost =$36.72
Last step is to compute for How much more money will she need to pay for text messages
Amount to be paid =$36.72-$9.00
Amount to be paid=$27.72
Therefore How much more money will she need to pay for text messages will be $27.72

The distance here varies directly with time. What is the constant of variation? (It is the hikers’ rate .)
Answer:
this is for you RSM people.
1 hour=13.5
2 hours=27
3 hours=40.5
3.5 hours=47.25
Step-by-step explanation:
The constant variation of the biker is the speed of the biker, Hence, the constant variation is 13.5 mph
Giveb the Parameters :
Distance biked = 9 miles Time taken = 2/3 hoursRecall :
Speed = distance / timeSpeed = 9 ÷ 2/3
Speed = 9 × 3/2
Speed = 27/2 = 13.5 miles per hour.

Big chickens: The weights of broilers (commercially raised chickens) are approximately normally distributed with mean 1387 grams and standard deviation 192 grams. Use the TI-84 Plus calculator to answer the following. (a) What proportion of broilers weigh between 1150 and 1308 grams? (b) What is the probability that a randomly selected broiler weighs more than 1510 grams? (c) Is it unusual for a broiler to weigh more than 1610 grams? Round the answers to at least four decimal places.
Answer:
a) 0.2318
b) 0.2609
c) No it is not unusual for a broiler to weigh more than 1610 grams
Step-by-step explanation:
We solve using z score formula
z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Mean 1387 grams and standard deviation 192 grams. Use the TI-84 Plus calculator to answer the following.
(a) What proportion of broilers weigh between 1150 and 1308 grams?
For 1150 grams
z = 1150 - 1387/192
= -1.23438
Probability value from Z-Table:
P(x = 1150) = 0.10853
For 1308 grams
z = 1308 - 1387/192
= -0.41146
Probability value from Z-Table:
P(x = 1308) = 0.34037
Proportion of broilers weigh between 1150 and 1308 grams is:
P(x = 1308) - P(x = 1150)
0.34037 - 0.10853
= 0.23184
≈ 0.2318
(b) What is the probability that a randomly selected broiler weighs more than 1510 grams?
1510 - 1387/192
= 0.64063
Probabilty value from Z-Table:
P(x<1510) = 0.73912
P(x>1510) = 1 - P(x<1510) = 0.26088
≈ 0.2609
(c) Is it unusual for a broiler to weigh more than 1610 grams?
1610- 1387/192
= 1.16146
Probability value from Z-Table:
P(x<1610) = 0.87727
P(x>1610) = 1 - P(x<1610) = 0.12273
≈ 0.1227
No it is not unusual for a broiler to weigh more than 1610 grams

Point P partitions directed segment AB in the ratio of 3:4.
What is the total number of congruent sections/parts? (what
is the k value?)
how many congruent sections are there
Answer:
Total number of congruent sections/parts = 7
[tex] k = \frac{3}{7} [/tex]
Step-by-step explanation:
Given that partitions directed segment AB such that AP : PB = 3 : 4, this implies that:
There are 7 parts/congruent sections that AB has been divided into.
Also, point P, partitions AB in the ratio 3:4.
Therefore, there are a total of 7 congruent sections/parts.
Value of k:
Value of k = numerator of the original ratio ÷ sum of numerator and denominator of the original ratio
[tex] k = \frac{3}{3 + 4} [/tex]
[tex] k = \frac{3}{7} [/tex]

How many grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% w/w of salicylic acid?
Answer:
4.79 g
Step-by-step explanation:
mass of salicylic acid = ??
Mass of polyethylene = 75 g
% w/w concentration = 6% w/w
Let the mass of salicylic acid be x
Let the mass of solution = 75 + x
from
% w/w = mass of solute/ mass of solution * 100
Hence concentration of salicylic is;
6 = (x/75 + x) * 100
6/100 = x/75 + x
0.06 (75 + x) = x
4.5 + 0.06x =x
4.5 = x-0.06x
x = 4.5/0.94
x= 4.79 g
4.79 grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% of salicylic acid.
To determine how many grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% of salicylic acid, the following calculation must be performed:
100 - 6 = 94 94 = 75 6 = X 6 x 75/94 = X 450/94 = X 4.7872 = X
Therefore, 4.79 grams of salicylic acid should be added to 75 g of a polyethylene glycol ointment to prepare an ointment containing 6% of salicylic acid.

Round to the nearest cent.
Timed test
Answer:
profit = revenue - cost
10 = 20x - (4.5 + 2.5)
10 = 20x - 7
10 + 7 = 20x
17 = 20x
17/20 = x
0.85 = x
check...
profit = revenue - cost
10 = 20(0.85) - 7
10 = 17 - 7
10 = 10 (correct)

You will use the GeoGebra geometry tool to divide a line segment in a given ratio. Go to line segment ratios, and complete each step below. If you need help, follow these instructions for using GeoGebra.
Question 1
Any line segment that is not horizontal or vertical can be represented as the hypotenuse of a right triangle whose legs are aligned with the x- and y-axes. In GeoGebra, is shown as the hypotenuse of such a triangle. You will divide in the ratio 2 : 3 using the ideas you’ve seen so far in the lesson:
Find and record the lengths of the horizontal and vertical sides of the right triangle.
Find and record the x-coordinate of a point that divides the horizontal side in the ratio 2 : 3. Use the formula from the lesson to guide you:
.
Find and record the y-coordinate of a point that divides the vertical side in the ratio 2 : 3. Use the formula from the lesson to guide you:
Consider a point C that has the x-coordinate of the point that divides the horizontal side in the ratio 2 : 3 and the y-coordinate of the point that divides the vertical side in the ratio 2 : 3. Write down the coordinates of point C. This is the point that divides in the ratio of 2 : 3.
Answer:
(2.6,1.8)
Step-by-step explanation:
length of horizontal side = (xB − xA) = 4 units
length of vertical side = (yB − yA) = 2 units
To find the x-coordinate of the point that divides the horizontal side in the ratio 2 : 3, first convert the ratio between the parts into the fraction of the sum that the first part is equal to: a/a+b= 2/2+3= 2/5
Multiply the length of the horizontal side by the fraction, and then add the result to the x-coordinate of point A: Xc= Xa + (a/a+b) (Xb - Xa) = 1+ (2/5 x 4) = 2.6
Multiply the length of the vertical side by the fraction, and then add the result to the y-coordinate of point A: Yc= Ya + (a/a+b) (Yb - Ya) = 1+ (2/5 x 2) = 1.8
It follows that point C is located at (2.6, 1.8).
Answer:
The coordinates of point C is (2.6,1.8)

Answer: $
A single lottery ticket costs $2. Compute the Expected Value, to you, if you purchase 10,000 lottery tickets. Round your answer to the nearest dollar.
Answer: $
Step-by-step explanation:
The order of the numbers doesn't matter, so we'll use combinations instead of permutations. The number of combinations is:
₄₅C₈ = 215,553,195
So the probability of a ticket having the winning combination is 1 / 215,553,195.
The expected value to the state is:
E(X) = 10,000 (1) ($2) + 10,000 (1 / 215,553,195) (-$1,000,000)
E(X) = $19954
The expected value to you is:
E(X) = 10,000 (1) (-$2) + 10,000 (1 / 215,553,195) ($1,000,000)
E(X) = -$19954
