Suppose that y varies inversely with x. Given x=-3 when y=-105. Find y when x=15
Answer:
21
Step-by-step explanation:
It is given that y varies inversely with x.
[tex]y\propto \dfrac{1}{x}[/tex]
[tex]y=\dfrac{k}{x}[/tex] ...(i)
where, k is constant of proportionality.
It is given that x=-3 when y=-105. Substitute these values in equation (i), to find the value of k.
[tex]-105=\dfrac{k}{-3}[/tex]
[tex]-105\times (-3)=k[/tex]
[tex]315=k[/tex]
Now,
[tex]y=\dfrac{315}{x}[/tex]
Substitute x=15 in the above equation.
[tex]y=\dfrac{315}{15}[/tex]
[tex]y=21[/tex]
Therefore, the value of y is 21 when x=15.

Answer:
a) Turned around and went back to their starting point
b) 8km/h
Step-by-step explanation:
a) the numbers on the left running vertically show the distance covered. When the line goes down again, it shows that Jo was taking away from the distance covered. After 10 minutes, Jo turned and went back to their starting point.
b) from 30 mins to 60 mins is half an hour. In that time, Jo covered 4km and therefore, if they continued at the same speed, in 1 hour (30 mins x 2), Jo would have covered 8km (4km x 2).
∴ Jo is travelling at 8km/h for the last half hour.

The product of (x+p)(x+q) can be written as x^2+(p+q)x+pq.
An intermediate step in this multiplication is
x^2+px+qx+pq=x^2+(p+q)x+pq.
Explain why px+qx=(p+q)x.
I'm Really confused please help!
Answer:
[tex]px+qx=(p+q)x[/tex] by taking out the common factors.
Step-by-step explanation:
It is given that the product of [tex](x+p)(x+q)[/tex] is [tex]x^2+(p+q)x+pq[/tex].
Given expression is
[tex](x+p)(x+q)[/tex]
Using distributive property, we get
[tex]x(x+q)+p(x+q)[/tex]
[tex]x(x)+q(x)+p(x)+p(q)[/tex]
[tex]x^2+qx+px+pq[/tex]
In middle terms px and qx the highest common factor is x. So taking out common factor from middle terms we get
[tex]x^2+x(q+p)+pq[/tex]
It can be written as
[tex]x^2+x(p+q)+pq[/tex]
Therefore, [tex]px+qx=(p+q)x[/tex] by taking out the common factors.

Solve for x.
-30 = 5(x+1)
Answer:
−30=5(x+1)
Step 1: Simplify both sides of the equation.
−30=5(x+1)
−30=(5)(x)+(5)(1)(Distribute)
−30=5x+5
Step 2: Flip the equation.
5x+5=−30
Step 3: Subtract 5 from both sides.
5x+5−5=−30−5
5x=−35
Step 4: Divide both sides by 5.
5x5=−355
x=−7
Answer:
x=−7
Answer:
x = -7
Step-by-step explanation:
Since this problem has the distributive property, we can simplify the problem.
-30 = 5x + 5
Now we have to subtract 5 from both sides because of the +5.
-35 = 5x
To find the answer, we have to move all the real numbers to one side, the variable on the other. To do this, we can simply divide both sides by 5.
-7 = x
x = -7

Answer:
2. 120 cm^2
3. 3,750 cm^2
Step-by-step explanation:
To find the surface area of a rectangular prism, find the surface area of each side, then add them together.
2. There are two different shapes of faces on this prism (as with all rectangular prisms). One face's surface area has a measure of 4 cm by 6m. To find the surface area of that face, multiply each side length. 4 * 6 = 24. Let's call this length A.
Then, find the surface area of the other face. The other face has a measurement of 4 cm by 3 cm. 4 * 3 = 12. Let's call this length B.
Now, find the amount of each face on the prism. Length A appears 4 times: the front, back, top, and bottom are all the same shape. Length B appears 2 times: the left and right sides. Therefore, multiply length A's surface area by 4 and length B's surface area by 2.
24 * 4 = 96
12 * 2 = 24
Lastly, add both numbers together.
96 + 24 = 120
Adding the label, we get the final answer: 120 cm^2.
3. Now, apply the same steps to problem #3.
One face has a measurement of 45 cm by 25 cm. This means that the surface area of that face is 1,125 cm. Let's call this length A.
The other face has a measurement of 15 by 25. This means that the surface are of that face is 375 cm. Let's call this length B.
Length B appears 4 times, and length A appears twice. Evaluating 375 * 4, we get 1,500. Evaluating 1,125 by 2, we get 2,250.
Lastly, adding 2,250 to 1,500 and adding the label, we get the final answer: 3,750 cm^2.

Kelly rolls two number cubes 50 times. After each roll, she records whether the number on
each cube is even (E) or odd (O). Her results are shown in the graph. Based on Kelly's results,
which is the most reasonable prediction for the number of times two odd numbers will occur
when two number cubes are rolled 2,000 times?
Answer:
480
Step-by-step explanation:
First add the numbers in the table together and put the total as a denominator in a fraction then the amount of times 2 odd numbers appeared as the numerator then put another fraction with 2,000 as the denominator and divide 2,000 by the total then multiply the numerator by that answer to get the correct answer.
Hope this helped!
Using fraction, When two number cubes are rolled 2,000 times , the number of times two odd numbers will occur is 480.
What is fraction?A fraction is " a number is expressed as a quotient in which numerator is divided by denominator".
According to the question,
Kelly rolls two number cubes 50 times, each cube is even (E) or odd (O).
The graph shows frequency of two numbered cube roll. The frequency of getting EO is 14, frequency of getting OE is 8, frequency of getting EE is 16 , frequency of getting OO is 12.
Total number of frequency = 14 + 8 + 16 + 12
= 50
The fraction of getting two odd numbers when cube is rolled 50 times
= [tex]\frac{12}{50}[/tex]. →(1)
In order to find, when two number cubes are rolled 2,000 times the number of times two odd numbers will occur.
= [tex]\frac{x}{2000}[/tex]. →(2)
Equating two fraction, to get value of 'x'.
[tex]\frac{12}{50} = \frac{x}{2000}[/tex]
[tex]\frac{12*2000}{50}[/tex] = x
x = 12 × 40
x = 480.
Hence, using fraction, When two number cubes are rolled 2,000 times , the number of times two odd numbers will occur is 480.

Katie has a cube with an edge length of
3 inches. Malea has a cube whose volume is 8
times greater than the volume of Katie's cube.
What is the length of Malea's cube?
Answer:
216 inches^3
Step-by-step explanation:
Volume= Length x Width x Height
Volume of Katie's cube is 3x3x3 (27 inches^3)
Malea's cube is 8x the volume of Katie's cube, so Malea's cube is 8 x 27, which is 216 inches^3
