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.

seth runs every day he jogs 6 miles a day onday through friday every saturday he jogs 8 miles and every sunday 5 miles how many miles in all will seth run in three weeks.
Show your work
Answers
Answer:129
Step-by-step explanation:You have 6 miles a day Monday through Friday,add that up to get 30 and multiply by 3 to get 90. Saturday is 8 so multiply that by 3 to get 24. Sunday is 5 miles so do times 3 to get 15 and add them all up
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The total miles covered in three weeks by Seth is 129 miles.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that Seth jogs 6 miles a day from Monday to Friday. Therefore, the total of miles for which Seth runs on weekdays is,
Total miles in weekdays = 6 miles × 5 days
= 30 miles
Also, Seth jogs 8 miles on every Saturday and 5 miles in every Sunday. Therefore, the total miles covered on week off days is,
Total miles on Saturday and Sunday = 8 miles + 5 miles
= 13 miles
Now, the total miles covered in a week is,
Total miles in a week = 30 miles + 13 miles = 43 miles
Further, the total miles covered in 3 weeks is,
Total miles in three weeks = 3 × 43 miles = 129 miles
Hence, the total miles covered in three weeks by Seth is 129 miles.

A. C = 16n; Continuous
B. C = 16 + n; Discrete
C. C = 16n; Discrete
D. C = 16 + n; Continuous
Answers
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.
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
Answers
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

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
Answers
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

Name each level of measurement for which data can be quantitative. Select all the levels of measurement for which data can be quantitative.
Answers
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.
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?
Answers
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
