What is the volume of a rock if it has a density of 1.25g/ml if it has a mass of 7525g?
Answer:
[tex]\boxed{\tt v= 6,020 \ mL}[/tex]
Step-by-step explanation:
The density formula is
[tex]d=\frac{m}{v}[/tex]
Rearrange the formula for v. Multiply both sides of the formula by v, then divide both sides by d.
[tex]d*v=\frac{m}{v}*v[/tex]
[tex]d*v=m[/tex]
[tex]\frac{dv}{d}=\frac{m}{d}[/tex]
[tex]v=\frac{m}{d}[/tex]
The volume can be found by dividing the mass by the density. The mass is 7525 grams and the density is 1.25 grams per milliliter.
[tex]m= 7525 \ g\\d=1.25 \ g/mL[/tex]
[tex]v=\frac{m}{d}[/tex]
[tex]v=\frac{7525\ g}{1.25\ g/mL}[/tex]
Divide. Note that the grams, or "g" will cancel each other out.
[tex]v=\frac{7525 \ }{1.25\ mL}[/tex]
[tex]v=6020 \ mL[/tex]
The volume of the rock is 6,020 milliliters.
Answer:
V = 6020
Step-by-step explanation:
will make it sure and simple
formula of density d = mass / volume
where d = 1.25 g/mL
and mass = 7525 g
plugin values into the formula
1.25 = 7525 / Vol
Vol = 7525 / 1.25
Vol = 6020

Starting with the number 10, build a sequence of 5 numbers.
Answer:
10, 26, 74, 218, 650
Step-by-step explanation:
n * 3 - 4
Answer:
The sequence of 5 terms is: 10, 26, 74, 218, 650
Step-by-step explanation:
By following the instructions, we can build the sequence by doing:
[tex]a_n= 3\,a_{n-1}-4[/tex]
So, using this formula and starting with 10 we get
[tex]a_1=10\\a_2=3\,(10)-4=26\\a_3=3\,(26)-4= 74\\a_4=3\,(74)-4=218\\a_5=3\,(218)-4=650[/tex]

Which of the following is a quadratic equation that has the roots x = 3 and x = −4?
Answer:
x^2 + x = 12
Step-by-step explanation:
(x - 3)(x + 4) = 0
x^2 + 4x - 3x - 12 = 0
x^2 + x - 12 = 0
x^2 + x = 12
The quadratic equation that has the roots x = 3 and x = −4 will be x²+x-12=0.
Any equation using the formula ax² + bx + c = 0 When x is a variable and a, b, and c are any real values; a quadratic equation is one where a≠0.
It is given that the quadratic equation that has the roots x = 3 and x = −4.
We know that one such equation is provided by x²-(a+b)x+ab=0 if a and b are the roots of a quadratic equation.
x²-(a+b)x+ab=0
Substitute the value of an as 3 and b as -4.
x²-(3-4)x+(3)(-4)=0
x²-(-1)x-12=0
x²+x-12=0
Thus, the obtained quadratic equation will be x²+x-12=0.

How much will a person pay for 1.4 pounds of bananas at a price of $2.34 per pound
Answer:
$3.276
Step-by-step explanation:
From the question, we are told that the price of banana is
1 pound = $2.34
1.4 pounds = $ y
Cross Multiply
1 pounds × $y = 1.4 pounds × $2.34
$y = 1.4 pounds × $2.34/1 pounds
$y = $3.276
Therefore, a person will pay $3.276 for 1.4 pounds of banana

It is said that a student’s college GPA (grade point index) can be predicted by his/her HOCS (higher- order cognitive skills) such as problem identification, analytical reasoning, and content integration skills. What other potential predictor variables, numerical and categorical, would you want to use that might lead to the development of a multiple regression model for predicting a student’s college GPA? Briefly describe the direction of the slope that each of these variables should have.
Answer:
apart from using the hoc to predict the college students gpa, some other variables can be used
1. the students intelligent quotient
2. ability to remember
3. study time
4. gym practice
Step-by-step explanation:
1. the students intelligent quotient
gpa has a positive relationship with iq. they are both directly related. The more the iq of a a student, the greater is his ability to understand and have a good gpa. the slope will therefore be positive and be in an upward direction.
2. ability to remember
the gpa of students who have a good ability to remember but do not have a good grasp of the subject may not be high. the slope would be in a slightly upward direction
3. study time
gpa and practice have a positive relationship. the more a student studies, the more likelihood exists of having a better gpa. the slope would be upward bound.
4. gym practice
gpa and gym practice are not related so the slope would be in a downward direction.
when interpreting the direction of relationship after carrying out such an analysis, it is useful to watch out for the accompanying signs of the variables. if the sign of the beta coefficient is positive then a positive relationship with the dependent variable exists.

Point B is the midpoint of point C and D. If CB is 14in, what is CD and BD?
Answer:
[tex]BD = 14\ in[/tex]
[tex]CD = 28\ in[/tex]
Step-by-step explanation:
Given
CB = 14in
B as midpoint
Required
Determine CD and BD
Since B is the midpoint, then the two line segments (CB and BD), we have the following relationships:
[tex]CB = BD[/tex]
[tex]CD = CB + BD[/tex]
Reorder the first equation
[tex]BD = CB[/tex]
Substitute 14 for CB
[tex]BD = 14\ in[/tex]
Taking the second equation into consideration
[tex]CD = CB + BD[/tex]
[tex]CD = 14 + 14[/tex]
[tex]CD = 28\ in[/tex]
