Answer:
p = 13, q = 9
Step-by-step explanation:
Given the 2 equations
[tex]\frac{q}{2}[/tex] - [tex]\frac{p}{3}[/tex] = [tex]\frac{1}{6}[/tex] ( multiply through by 6 to clear the fractions )
3q - 2p = 1 → (1)
[tex]\frac{p}{2}[/tex] - [tex]\frac{q}{6}[/tex] = 5 ( multiply through by 6 to clear the fractions )
3p - q = 30 , that is
- q + 3p = 30 → (2)
Multiplying (2) by 3 and adding to (1) eliminates the term in q
- 3q + 9p = 90 → (3)
Add (1) and (3) term by term to eliminate q
7p = 91 ( divide both sides by 7 )
p = 13
Substitute p = 13 into (2) for corresponding value of q
- q + 3(13) = 30
- q + 39 = 30 ( subtract 39 from both sides )
- q = - 9 ( multiply both sides by - 1 )
q = 9
Thus p = 13 and q = 9

Which Correlation is most likely a causation?
A. The positive Correlation between the number of skiers and snowboarders on a mountain.
B. The positive Correlation between the number of typing classes a student takes and the number of words per minute the student can type.
C. The positive Correlation between the sales of cell phones and the sales of televisions in a store.
D. The positive Correlation between the number of shopping carts at a store and the number of cash registers in the store.
Answer:
C and B
Step-by-step explanation:
in x=5.9x-19.5 the y int is -19.5 (y=mx+b m = slope b =y int)
According to the information they earn 5.9 of something "every payday" and the y int is them starting out. The only logical answer is C for the first question because every other answer involves slope and not starting value.
For the second one it is B i think since causation means cause to effect or ratio. They are the only values that make since because they are related to eachother.
Sorry for the bad spelling if you need any more information please ask in comments :)
The answers of question 1 and question 2 are option C and B respectively.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction
Given equation,
y = 5.9x - 19.5
And we have the slope intercept form
y = mx + b,
where m is the slope and b is the y-intercept.
Comparing above of both the equation,
Here, the y intercept is -19.5 and the slope is 5.9
According to the information they earn 5.9 of something "every payday" and the y intercept is them starting out.
The answer is C for the first question because every other answer involves years that means slope and not starting value.
For the second one,
answer is B i think since causation means cause to effect or ratio.
The positive Correlation between the number of typing classes a student takes and the number of words per minute the student can type.
Relation is directly related to each other.
Therefore, the answers of question 1 and question 2 are option C and B respectively.

Sam read 6 chapters in 2 hours. If he continues to read at this same rate, how many chapters will he read in 1 day?
Answer:
He will read 72 chapters in 1 day
Step-by-step explanation:
Let us use the ratio method to solve this question
∵ Sam read 6 chapters in 2 hours
∵ He continues to read at this same rate for 1 day
→ We must change the day to hours
∵ 1 day = 24 hours
∴ We need to find how many chapters he will read in 24 hours
→ Chapter : Hour
→ 6 : 2
→ x : 24
→ By using cross multiplication
∵ x × 2 = 6 × 24
∴ 2x = 144
→ Divide both sides by 2
∵ [tex]\frac{2x}{2}[/tex] = [tex]\frac{144}{2}[/tex]
∴ x = 72
∴ He will read 72 chapters in 1 day

A number cube is tossed 50 times, and a 2 is rolled 14 times. Find the experimental probability of not rolling a 2. Enter your answer as a simplified fraction.
Answer:
18/25
Step-by-step explanation:
With regards to the above information, we can infer that since a 2 is rolled 14 times, then 36[50 - 14]rolls are not 2.
The experimental probability would then be;
= 36/50
= 18/25
The experimental probability of not rolling a 2 is 18/25.

Determine which of the lines, if any are perpendicular.
Line a passes through (2, 10) and (4, 13).
Line b passes through (4, 9) and (6, 12).
Line c passes through (2, 10) and (4, 9).
Given:
Line a passes through (2, 10) and (4, 13).
Line b passes through (4, 9) and (6, 12).
Line c passes through (2, 10) and (4, 9).
To find:
Which of the lines, if any are perpendicular.
Solution:
If a line passes through two points, then the slope of line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Line a passes through (2, 10) and (4, 13). So, slope of this line is
[tex]m_a=\dfrac{13-10}{4-2}=\dfrac{3}{2}[/tex]
Line b passes through (4, 9) and (6, 12). So, slope of this line is
[tex]m_b=\dfrac{12-9}{6-4}=\dfrac{3}{2}[/tex]
Line c passes through (2, 10) and (4,9). So, slope of this line is
[tex]m_c=\dfrac{9-10}{4-2}=\dfrac{-1}{2}[/tex]
Product of slopes of to perpendicular lines is -1.
[tex]m_a\cdot m_b=\dfrac{3}{2}\times \dfrac{3}{2}=\dfrac{9}{4}\neq -1[/tex]
[tex]m_b\cdot m_c=\dfrac{3}{2}\times \dfrac{-1}{2}=\dfrac{-3}{4}\neq -1[/tex]
[tex]m_a\cdot m_c=\dfrac{3}{2}\times \dfrac{-1}{2}=\dfrac{-3}{4}\neq -1[/tex]
Therefore, any of these lines are not perpendicular to each other.

4. X varies directly with the square of y, where x>0,
and y >0. If x= 3 when y = 5, then what is the value
ofy when x= 48?
Answer:
The value of y, when x = 48 is y = 12/5
Step-by-step explanation:
The given parameters are;
x is directly proportional to y
Where x > 0, y > 0
For x = 3. y = 5
Therefore, we have;
x ∝ a·y²
For ,x = 3, when y = 5, we have;
3 = a × 5² = 25·a
∴ a = 25/3
When x = 48, we have;
48 = 25/3×y²
y² = 3/25 × 48 = 144/25
y = √(144/25) = 12/5
y = 12/5
The value of y, when x = 48 is y = 12/5.

Answer:
4C, 5D, 6A, 7E, 8B, 9s
Step-by-step explanation:
This is a vocabulary question. The angles named by the relationships A-E are angles that have the transversal as a common side. "Interior" and "exterior" refers to the space between the crossing lines, or outside the crossing lines, respectively. "Alternate" means the angles are on opposite sides of the transversal; "consecutive" means they are on the same side of the transversal.
Angles are "corresponding" if they are in the same direction from the point of intersection where the transversal crosses the two lines. The angles will be "consecutive", but one will be interior and the other will be exterior.
4. angle 9 is left of q, above r; angle 16 is right of q and below s, so these are alternate exterior angles, C.
__
5. angle 3 is below r and left of p; angle 5 is above s and left of p, so these are consecutive interior angles, D.
__
6. angle 7 is below s and left of p; angle 15 is below s and left of q, so these are corresponding angles, A.
__
7. angle 1 is above r and left of p; angle 10 is above r and right of q, so these are consecutive exterior angles, E.
__
8. angle 2 is above r and right of p; angle 11 is below r and left of q, so these are alternate interior angles, B.
__
9. angles 6 and 13 are above transversal s.
the sum of the speeds of two trains is 721.6 miles per hour. if the speed of the first train is 8.4 mph faster than that of the second train find the speeds of each
Subtract the faster speed:
721.6 - 8.4 = 713.2
Divide by 2 trains:
713.2/2 = 356.6
The slower train is going 356.6 miles per hour.
The faster train is going 356.6 + 8.4 = 365 miles per hour.

☯ Question :Find the area of a circle that has a circumference of 175.84 inches.☯ Step - by - step explanation :☄ Given :
Circumference of a circle = 175.84 inches☄ To find :
Area of a circle = ?☄ First, we have to find :
Radius of a circle ( r )♨ Finding the radius of a circle :
[tex] \boxed{ \sf{Circumference \: of \: a \: circle = 2\pi \: r}}[/tex]
Substitute the value of circumference of a circle
[tex] \longrightarrow{ \sf{175.84 = 2\pi \: r}}[/tex]
Swap the sides of the equation
⟶ [tex] \sf{2\pi \: r \: = 175.84}[/tex]
Use [tex] \sf{ \pi \: ≈ \: 3.14}[/tex] , we obtain
[tex] \longrightarrow{ \sf{2 \times 3.14 \times r = 175.84}}[/tex]
Multiply : 2 by 3.14
[tex] \longrightarrow{ \sf{6.28 \: r = 175.84}}[/tex]
Divide both sides by 6.28
[tex] \longrightarrow{ \sf{ \frac{6.28 \: r}{6.28} = \frac{175.84}{6.28}}} [/tex]
[tex] \longrightarrow{ \sf{r \: = \: 28 \: inches}}[/tex]
☞ Now , we have :
Radius of a circle ( r ) = 28 inchesFinding the area of a circle having the radius of 28 inches :
[tex] \boxed{ \sf{Area \: of \: a \: circle = \pi \: {r}^{2} }}[/tex]
Substituting the radius , we get :
[tex] \longrightarrow{ \sf{Area \: of \: a \: circle = \pi \: {(28)}^{2} }}[/tex]
[tex] \longrightarrow{ \sf{Area \: of \: a \: circle = 784 \: \pi}}[/tex]
Using [tex] \sf{\pi \: ≈ \: 3.14}[/tex] , we obtain :
[tex] \longrightarrow{ \sf{Area \: of \: a \: circle = 784 \times 3.14 }}[/tex]
[tex] \longrightarrow{ \boxed{ \sf{Area \: of \: a \: circle = 2461.76 \: {inches}^{2} }}}[/tex]
Therefore , area of a circle is 2461.76 inches²

A triangle has sides with lengths of 26 meters, 39 meters, and 43 meters. Is it a right triangle?
Answer: No
Step-by-step explanation:
This triangle is not a right triangle because:
A right triangle must have one side that is exactly 90°.
A triangle with sides 26, 39, and 43 do not have any sides that total 90.
The answer to your question is no.
Best of Luck!
Answer:
No, the side don't equal 90
