Beginning of diet, 13 stone 12 pounds
13(14) + 12 = 194
Three months later, 12 stone 10 pounds
12(14) + 10 = 178
He lost 16 pounds in 3 months
I'm not really sure what the percentage would be, but it might be 16%

Step-by-step explanation:
A triangle has two sides that have lengths of 37 cm and 19 cm. Which could represent the possible length of the third side?
Answer:
[tex]18cm<X<56cm[/tex]
Step-by-step explanation:
From the question we are told that
First side 37 cm
Second side 19 cm
Generally considering the triangle inequality theorem we have
[tex]37+19>X\\X+37>19\\X+19>37[/tex]
Solving equations we have
[tex]X<56\\X>18\\X>-18[/tex]
Generally from the inequalities the range of X is mathematically given as
[tex]X>18\\X<56[/tex]
[tex]18cm<X<56cm[/tex]
Therefore the range of the Third side is
[tex]18cm<X<56cm[/tex]
Jim has gotten scores of 79 and 70 on his first two test. What score must he get on his third test to keep an average of 96 or greater?
Answer:
he must get at least 139... which isn't really possible lol
Step-by-step explanation:
(79+70+x)/3 > 96
149+x > 288
x > 139
drake has nickels, dimes, and quarters in his pocket. The 18 coins have a value of $2.30. If there are three times as many dimes as quarters, how many nickels are there
Answer:
4 quarters=1.00
12 dimes=1.20
+2 nickles=0.10
18 coins=2.30
Step-by-step explanation:
So there are 4 quarters, 12 dimes, and 2 nickels.

A movie store sells DVDs for $16 each. What is the cost, "C", of "n" DVDs? Is the data Continuous or Discrete?
A. C = 16n; Continuous
B. C = 16 + n; Discrete
C. C = 16n; Discrete
D. C = 16 + n; Continuous
Answer: C = 16n; Discrete
Step-by-step explanation:
From the question, a movie store sells DVDs for $16 each. The cost, "C", of "n" DVDs will be calculated by multiplying $16 by n. This will be:
C = 16 × n
C = 16n
This is dicrete as the valuea that'll be gotten will take some particular values.

A scientist studying water quality measures the lead level in parts per billion (ppb) at each of 49 randomly chosen locations along a water line. Suppose that the lead levels across all the locations on this line are strongly skewed to the right with a mean of ppb17 and a standard deviation of 14ppb. Assume that the measurements in the sample are independent.
Required:
What is the probability that the mean lead level from the sample of 49 measurements T is less than 15 ppb?
Answer:
The probability that the mean lead level from the sample of 49 measurements T is less than 15 ppb
P(x⁻< 15) = 0.1587
Step-by-step explanation:
Step(i):-
Given that the size of the sample 'n' =49
Mean of the Population = 17ppb
The standard deviation of the population = 14ppb
Let 'X' be the random variable in a normal distribution
[tex]Z = \frac{x-mean}{\frac{S.D}{\sqrt{n} } } = \frac{15-17}{\frac{14}{\sqrt{49} } } = -1[/tex]
Step(ii):-
The probability that the mean lead level from the sample of 49 measurements T is less than 15 ppb
P(x⁻< 15) = P(Z<-1) = 1-P(Z>-1)
= 1-(0.5+A(-1))
= 0.5 - A(1)
= 0.5-0.3413
= 0.1587
Final answer:-
The probability that the mean lead level from the sample of 49 measurements T is less than 15 ppb
P(x⁻< 15) = 0.1587

f(3)= 5x^2 - 4x + 9
evaluate this quadratic function
Answer:
[tex]f(3) = 38[/tex]
Step-by-step explanation:
Given the quadratic function
[tex]f\left(x\right)=\:5x^2\:-\:4x\:+\:9[/tex]
Evaluating the quadratic function
[tex]f\left(x\right)=\:5x^2\:-\:4x\:+\:9[/tex]
substitute x = 3
[tex]f\left(3\right)=\:5\left(3\right)^2\:-\:4\left(4\right)\:+\:9[/tex]
[tex]f(3) = 45-16+9[/tex]
[tex]f(3) = 38[/tex]
Therefore,

Answer:
z=15
Step-by-step explanation:
45 = 3z Because there are three z's, equal to one 45.
45 = 3z
z = 15
Answer:
B. 45 = 3x
x = 15
Step-by-step explanation:
3 triangles worth "z" value each, is equal to 1 square equivalent to 45 in value. This means that 3z = 45. This means that z = 15, becuase, 3 * 15 = 45.

Name each level of measurement for which data can be quantitative. Select all the levels of measurement for which data can be quantitative.
Answer: Interval, Ratio, ordinal
Step-by-step explanation:
Quantitative data refers to data with numerical variables and have numerical meaning for which mathematical inferences can be made. The interval scale is used are used only for quantitative variables. They provide an fixed and ordered arrangement on their scale and also provide useful and reasonable differences in values.
The ratio scale is another quantitative scale which is very similar to the interval scale, providing meaningful difference between the values. The ratio scale gives a true zero (zero here means none) value which is different from interval whose zero value does not mean real zero.
The ordinal scale can be applied to both Qualitative and quantitative variables, the scale gives a rank and ordered meaning to measurement. However, the numbers or scale values cannot be used for mathematical computation as they'll provide no useful meaning.

6x−5>−29
x −4
x>4
Answer:
x>4
Step-by-step explanation:
Answer: x>-4
Step-by-step explanation:
1. Add five to both sides [ this will cancel out the five ]
6x - 5 > -29
+5 +5
----------------------
6x > -24
2. Divide by six on both sides
6x > -24
---- ------

Consumable resources are used up as you build goods or deliver services in your business. If your business uses on average 6 ounces of milk in a shake and serves 86 shakes per day, how many gallons of milk do you need to order each week? (1 gallon = 128 ounces)
a) 25
b) 27
c) 29
d) 32
Note: I think it is either 27 or 29 because when you do the math, you get 28.21875. I took 6 × 86 = 516, 516 ÷ 128 = 4.02125 × 7 = 28.21875
Complete Question
Answer:
28.21875 gallons
Step-by-step explanation:
Step 1
From the above question:
1 shake = 6 ounces of milk
86 shakes = x
Cross Multiply
x = 86 × 6 ounces of milk
x = 516 ounces of milk
Step 2
1 gallon = 128 ounces
Hence:
For 1 day
128 ounces of milk = 1 gallon
516 ounces of milks = x gallon
Cross Multiply
128 ounces × x = 516 ounces × 1
x = 516 ounces /128 ounces
x = 4.03125 gallons
For 1 week = 7 days
1 days = 4.03125 gallons
7 days = x
Cross Multiply
x = 7 × 4.03125
x = 28.21875 gallons
Therefore, she needs to order 28.21875 gallons of milk each week

13 points!! Mikes bikes charges an initial fee of $10 to rent a bike plus $5 per hour (h) of use. If the total cost (t) can be determined using the equation t=10+5h, what is the greatest number of hours someone can rent a bike for $25
Answer:
Greatest number of hours = 3
Step-by-step explanation:
Given that:
Initial charges = $10
Per hour charges = $5
Number of hours = h
Equation;
t = 10 + 5h
For finding the hours for $25, we will put t=25 in the equation
25 = 10 + 5h
25 - 10 = 5h
5h = 15
Dividing both sides by 5
[tex]\frac{5h}{5}=\frac{15}{5}\\h=3[/tex]
Hence,
Greatest number of hours = 3
Answer:
3
