Raina runs each lap in 8 minutes. She will run more than 9 laps today. What are the possible numbers of minutes she will run today? Use t for the number of minutes she will run today. Write your answer as an inequality solved for t.
Considering the definition of an inequality, the number of minutes she will run today will be more than 72 minutes.
Definition of inequalityAn inequality is the existing inequality between two algebraic expressions, connected through the signs:
greater than >.less than <.less than or equal to ≤.greater than or equal to ≥.An inequality contains one or more unknown values called unknowns.
Solving an inequality consists of finding all the values of the unknown for which the inequality relation holds.
Inequality in this caseIn this case, you know that:
Raina runs each lap in 8 minutes. She will run more than 9 laps today.Being "t" the number of minutes Raina will run today, the inequality is
t÷ 8> 9
Solving:
t > 9×8
t > 72 minutes
Finally, the number of minutes she will run today will be more than 72 minutes.

$2.25. How much does the pen cost?
| Total = $2.25
Answer:1.05
Step-by-step explanation:
total = 2.25
pen = x
notebook = x+0.15
2x+0.15=2.25
2x=2.10
x=1.05
pen = 1.05
The distance, d, traveled by a particle is directly proportional to the square of the time, t, taken. when t = 40, d = 30. find a formula for d in terms of t.
If the distance,d, traveled by a particle is directly proportional to the square of the time,t, taken, when t = 40, d = 30, then the formula for d in terms of t will be d = 0.01875(t²).
Proportionality can be described as the property of being in a proper correlation in terms of size or quantity. In this problem, the distance is directly proportional to the square of the time which means that the distance increases as the square of the time is increased and vice versa.
Therefore,
d ∝ t²
d = kt² ( when t = 40 and d = 30 )
Here k is the constant
The value of k can be found by rearranging the equation,
d = kt²
30 = k(40²)
30 = k(1600)
k = 30 / 1600
k = 0.01875
As k = 0.01875, the formula for d in terms of t can be given as,
d = kt²
d = 0.01875(t²)

[tex]u_{2} = 2 \: \: \: \: \: \: u_{6} = - 14 \\ u_{1} + (2 - 1)d = 2 \\ u_{1} + (6 - 1)d = - 14[/tex]

Answer: a₁=6 a₉=-26
Step-by-step explanation:
a₂=2 a₆=-14 a₁=? a₉=?
a₂=a₁+(2-1)d
a₆=a₁+(6-1)d
a₁+d=2 (1)
a₁+5d=-14 (2)
Subtract equation (1) from equation (2):

Divide both parts of the equation by 4:
d=-4
Hence,
a₁+(-4)=2
a₁-4+4=2+4
a₁=6

i
The unknown angles on the straight line are as follows:
m∠RQS = 109° m∠TQS = 71°How to find angles?∠RQT is a straight angle.
Therefore,
∠RQT = 180 degrees(angle on a straight line)
Therefore, let's find m∠RQS and m∠TQS
∠RQT = m∠RQS + m∠TQS
where,
m∠RQS = 10x + 9
m∠TQS = 7x + 1
Therefore,
∠RQT = 10x + 9 + 7x + 1
∠RQT = 17x + 10
180 - 10 = 17x
170 = 17x
divide both sides by 17
x = 170 / 17
x = 10
Therefore,
m∠RQS = 10(10) + 9 = 109°
m∠TQS = 7(10) + 1 = 71°

x/3.5 = 20/1.4 get it to be equal
Answer:
x is 50.
Explanation:
3.5 and 1.4 are both at the bottom of the fraction (denominators), so divide 3.5 by 1.4 to get 2.5.
Then, multiply 20 by 2.5.
This makes sense because 3.5 is greater than 1.4, and the final answer (50) is greater than 20.
We can always check by dividing 50 by 3.5 and 20 by 1.4. See if it is the same number.

Given in the picture that [tex]D=b^{2} -4ac[/tex]. and the value of Quadratic equation is [tex]b=\sqrt{65}[/tex].
(a) Express b in terms of a, c and D.
[tex]b=\sqrt{D-4ac}[/tex]
(b) Find the values of b when a=2, c=-2 and D=81.
[tex]b=\sqrt{65}[/tex]
By seeing the question we can say that the [tex]b^{2} -4ac[/tex] is in the quadratic formula.
We know the general Quadratic Equation is [tex]ax^{2}+bx+c=0[/tex].
The solution to find the root of the Quadratic Equation is Quadratic Formula: [tex]\frac{-b\pm\sqrt{b^{2}-4ac } }{2a}[/tex].
The whole solution is depend on [tex]b^{2} -4ac[/tex]. The team is called discriminant.
(a) Given that,
[tex]D=b^{2} -4ac[/tex]
[tex]b^{2}=D +4ac\\[/tex]
Taking square root on both sides.
[tex]\sqrt{b^{2} } =\sqrt{D+4ac}\\ b=\sqrt{D+4ac}\\[/tex]
Therefore, [tex]b=\sqrt{D-4ac}[/tex]
(b) Given that,
a=2,c=-2 and D=81
[tex]b=\sqrt{D+4ac}\\[/tex]
[tex]b=\sqrt{81+4(2)(-2)}\\[/tex]
[tex]b=\sqrt{81-16}[/tex]
[tex]b=\sqrt{65}[/tex]
Therefore, [tex]b=\sqrt{65}[/tex]
A quadratic equation is a second-degree algebraic equation in x. In its usual form, the quadratic equation is a[tex]x^2[/tex] + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant factor.

suppose you are conducting a survey regarding illicit drug use among teenagers in the baltimore school district. you obtain a cluster sample of 12 schools within the district and sample all sophomore students in the randomly selected schools. the survey is administered by the teachers.
Response bias results from the possibility that not all sophomore students provided accurate information about their drug use, which will immediately result in the response bias because of false data.
What is response bias?
Response bias is a catch-all phrase for a variety of inclinations for participants to give misleading or inaccurate answers to queries. These biases are common in studies involving participant self-report, such as structured interviews or surveys. The validity of questionnaires or surveys can be significantly impacted by response biases.
The idea that human subjects do not passively respond to stimuli but rather actively integrate several sources of information to develop a response in a specific scenario is central to the concept that response bias can be induced or caused by a variety of causes. As a result, practically every element of an experimental condition has the ability to sway a respondent.
Explanation:
The remedy is to conduct a survey by licensed social workers since licensed social workers didn't explicitly ask sophomore students about drug use; instead, they interacted with the students as their friends before gathering the data.

the phosphorus levels are low. In 10% of the samples both the nitrogen and the phosphorus
levels are low. What percentage of the samples have nitrogen levels or phosphorus levels
that are low?
In linear equations, 64% of samples have nitrogen levels and phosphorus levels that are low.
What is linear equations?
A linear equation with one variable is one that contains just one variable. It has the formula Ax + B = 0, with A and B being any two real numbers and x being an ambiguous variable with only one possible value. One such linear equation in one variable is 9x + 78 = 18.P(low nitrogen) = 46% = 0.46
P(low phosphorus) = 28% = 0.28
P(low nitrogen and low phosphorus) = 10% = 0.10
P(low nitrogen or low phosphorus) = P(low nitrogen) + P(low phosphorus) - P(low nitrogen and low phosphorus)
= 0.46 + 0.28 - 0.10
= 0.64 = 64%
Hence , 64% of samples have nitrogen levels and phosphorus levels that are low.

Step-by-step explanation:

Ori : part is right, but part is not
Kaori : incorrect
Daniela would not even have to say, that the lines are distinct. in any case, yes if you don't change anything about the appearance of the lines, but can move them on top of each other. and they completely blend in with each other, then yes they are parallel.
Ori is wrong about the part that they have to be close together. the second line could be in another galaxy, but if they are in the same plane and never intersect each other, then they are parallel.
Kaori is wrong by understanding that parallel means to opposite of perpendicular. perpendicular just means that the 2 lines are intersecting each other at a right angle (90°). but they can intersect at any other angle. that makes them not perpendicular, but they still intersect each other. so, they are not parallel.

Answer:
∠ TVW = 65°
Step-by-step explanation:
∠ UVW = ∠ TVW + ∠ UVT ( substitute values )
21x + 6 = 8x + 9 + 88
21x + 6 = 8x + 97 ( subtract 8x from both sides )
13x + 6 = 97 ( subtract 6 from both sides )
13x = 91 ( divide both sides by 13 )
x = 7
Then
∠ TVW = 8x + 9 = 8(7) + 9 = 56 + 9 = 65°
