Step-by-step explanation:
You and your brother are reading the same novel. You want to get ahead of him in the book, so you decide to read 30 minutes longer than your brother reads.
For this case we have the following notation:
y= the number of minutes that you read
x = the number of minutes that your brother read
And we have that you decide to read 30 minutes longer than your brother, so the equation would be:
y = x+30
And for the other part of the question if x =15 we got:
y = 15+30 = 45
Step-by-step explanation:Assuming this complete question: "You and your brother are reading the same novel. You want to get ahead of him in the book, so you decide to read 30 minutes longer than your brother reads. Write an equation for the number of minutes you read, y, when your brother reads x number of minutes.
How many minutes will you read if your brother reads for 15 minutes?"
Solution to the problemFor this case we have the following notation:
y= the number of minutes that you read
x = the number of minutes that your brother read
And we have that you decide to read 30 minutes longer than your brother, so the equation would be:
y = x+30
And for the other part of the question if x =15 we got:
y = 15+30 = 45

What is a perpendicular bisector?A perpendicular bisector of a line segment is a line segment that is perpendicular to and passes through the middle of the line segment (left figure). A line segment's perpendicular bisector can be drawn using a compass by drawing circles centred at and with radius and connecting their two intersections.

suppose y is directly proportional to x and y=40 when x=10 find y if x=16
Answer:
64
Step-by-step explanation:
16/10=1.6 and 1.6x40=64
Answer: y = 64
Step-by-step explanation:
[tex]$$Given, \\$y$ is directly proportional to $x$ \\$\Rightarrow y \propto x$ (Note: ' $\alpha$ ' be proportion/various sign) \\$\Rightarrow y=k x$ ( $k$ be the constant) \\$\therefore y=k x-$ (1)[/tex]
[tex]$$Given $y=40$ when $x=10$.So, substitute $y=40 \ \& \ x=10$ in (1) we get,$$\begin{aligned}&\Rightarrow 40=k(10) \\&\Rightarrow 10 k=40 \\&\Rightarrow k=\frac{40}{10} \text { (divide '10' both sides) } \\&\Rightarrow k=4\end{aligned}$$[/tex]
[tex]$$Put $k=4$ in (1) we get,$$y=4 x$$We substitute $x=16$ in (2) we get$$\begin{aligned}y &=4(16) \\\Rightarrow y &=64 \\\end{aligned}$$[/tex]

The temperature at midnight was -8°C. The temperature at 5 am was -3°C. (a) Work out the difference between the two temperatures. (b) The temperature at midday was 9°C higher than the temperature at 5 am.. Work out the temperature at midday.
a) The difference between the temperatures is 5°c.
b) We will see that at midday, the temperature is 12°C.
How to find the differences between the temperatures?
We know that at midnight the temperature was T = -8°C, and at 5am the temperature was T' = -3°C.
a) First we want to find the difference between the temperatures, we can compute that directly:
T' - T = -3°C - (-8°C) = 5°C
This means that the temperature increased 5°C in that time interval.
b) At midday, the temperature was 9°C higher than at 5am, this means that:
T'' - T' = 9°C
T'' - 3°C = 9°C
Now we can solve this for T''
T'' = 9°C + 3°C = 12°C
At midday, the temperature is 12°C.

1. Are the side lengths congruent?
2. Are the opposite sides parallel?
3. Are the adjacent sides perpendicular?
Answer:
1:If three pairs of sides of two triangles are equal in length, then the triangles are congruent. ASA (angle-side-angle): If two pairs of angles of two triangles are equal in measurement, and the included sides are equal in length, then the triangles are congruent. 2:All sides are equal in length. Diagonals bisect each other at a 90-degree angle. The sum of any two adjacent interior angles is 180 degrees. Opposite sides are equal and parallel to each other.3:Each pair of opposite sides is parallel, and adjacent sides are perpendicular. This means that every angle in a rectangle is a right (90∘) angle.

If the volume of a cylinder is 847pi yds^3 and the height is 7 yards, what is the radius?
The radius of the given cylinder of volume 847π yds³ and height of 7 yards is 11 yards
Calculating the volume of a cylinderFrom the question, we are to calculate the radius of the cylinder
The volume of a cylinder is given by the formula,
[tex]V = \pi r^{2}h[/tex]
Where V is the volume
r is the radius
and h is the height
From the given information,
V = 847π yds³
h = 7 yds
Putting the parameters into the equation, we get
[tex]847\pi = \pi r^{2} \times 7[/tex]
[tex]7r^{2} = 847[/tex]
[tex]r^{2} = \frac{847}{7}[/tex]
[tex]r^{2} = 121[/tex]
[tex]r =\sqrt{121}[/tex]
r = 11 yards
Hence, the radius of the given cylinder is 11 yards.
