Answer:
12900
Step-by-step explanation:
umm first you write down the number of zeros (but only the zeros at last if a zero comes in middle or between other numbers, then you must have to multiply it) and then multiply the remaining numbers. I am not good at explaining. ;)
Study the equation from part c. What operation must you preform to both sides of the equation to get x by itself on the right side?
Answer:
To isolate x on the right side of the equation, multiply both sides of the equation by 24, or 24/1
Step-by-step explanation:
(24/1) 9/2 = x/24 (24/1)

Write a function rule for the table.
OC= 220 + 12
Oc= 220
Oc= 220 + 22
O c = 120 + 22
Answer:
c = 22o + 12
Step-by-step explanation:
As input values increase by 1, output values increase by 56-34=22. The output value for o=1 is 12 more than 22o, so the function rule seems to be
c = 22o +12
__
Based on answer choices, we assume that input is o, and output is c. '0' is not a variable.

A solution is prepared by dissolving
24 milliliters of saline in 150 milliliters of pure
solution. What is the percent of saline in the pure
solution?
Answer:
13.79%
Step-by-step explanation:
A solution is made by dissolving 24 millimeters of saline in 150 millimeters of pure solution
Therefore percent of saline in the pure solution can be calculated as follows
= 24/24+150 × 100
= 24/174 ×100
= 0.1379 ×100
= 13.79%
Hence the percent of saline in the pure solution is 13.79%

A biologist measured the length and mass of 20 reptiles. the equation
y = 0.3x - 2 is the line of the best fit for data, where x is the length, in centimeters, and y is the mass in grams.
Based on the equation, what is the approximate length of a reptile that has a mass of 20.5 grams?
a. 62 cm
b. 66 cm
c. 70 cm
d. 75 cm
Please answer quickly!!
D. 75 cm
Step-by-step explanation:
fill in the y with 20.5, so you get 20.5=0.3x-2. Add the 2 to the 20.5 so you get 22.5=0.3x. Divide both by 0.3 to get 75=x.

The following equation defines f(x)=-3x-5 . If (-5,n) is an ordered pair of the function rule, what is the value of n?
Given:
The function is
[tex]f(x)=-3x-5[/tex]
(-5,n) is an ordered pair of the function rule.
To find:
The value of n.
Solution:
If (-5,n) is an ordered pair of the function rule, then the function must be satisfied by the point (-5,n). It means f(-5)=n.
Substitute x=-5 in the given function.
[tex]f(-5)=-3(-5)-5[/tex]
[tex]f(-5)=15-5[/tex]
[tex]f(-5)=10[/tex]
We know that, [tex]f(-5)=n[/tex]. So,
[tex]n=10[/tex]
Therefore, the value of n is 10.
a car rental company charges $30 per day to rent a car plus $0.02 per mile driven. which equation represents c, the total cost to rent a car for 5 days, when m is the total number of miles driven?
Answer:
c=0.02(m)+30(5)
or
c= 150+0.02(m)
or
c=0.02(m)+150
or
c=30(5)+0.02(m)
Step-by-step explanation:
This is because c, or cost is equal to 30 dollars a day as a base fee or 150 total for five days plus 0.02 per mile. So, if you multiple the mileage driven by 0.02 and add 150 for the 30$ per day at 5 days. This is your equation
These are just different ways you could write that since it is clear you have a multiple choice question

In a city with three high schools, all the ninth graders took a Standardized Test, with these results:High Scool Mean Score test Number of ninth gradeGlenwood 79 285Central city 94 336Lincoln High 72 191The city's PR manager, who never took statistics, claimed the mean score of all ninth graders in the city was 81.7 . Of course, that is incorrect. What is the mean score for all ninth graders in the city? USE EXCEL. Round your answer to one decimal place.
Answer: 83.56
Step-by-step explanation:
To calculate the mean score for all ninth graders in the city, we multiply the mean score test for each school by the number of months grade students and then add all together and divide by the total ninth grade students. This is solved below.
Mean = [(79 × 285) + (94 × 336) + (72 × 191)]/285+336+191
= (22515+31584+13752)/812
= 67851/812
= 83.56

Answer:
Robert is 10 and his dad is 40 years old
Step-by-step explanation:
We have (4x+5)=3(x+5)
4x+5=3x+15
x=10.
Roberts is 10 years old and his father is 40 years old.
Answer:
Step-by-step explanation:
Roberts's father=4x
Robert=x
After 5 years, the ages will be
4x+5 and x+5 because we just simply add 5 years to their ages
It says that the father will be 3x older. So,
3(x+5)=4x+5. --this is the equation
3x+15=4x+5
-5 -5
3x+10=4x
-3x -3x
x=10
