Your answer will be ~ 611.

The third angle of the triangle will be ∠B = 71°.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

Given that:-

The third angle will be calculated as:-

∠A   + ∠C + ∠B = 180

42  +  67  +  ∠B = 180

∠B = 180 - 42 - 67

∠B =  71°

Therefore the third angle of the triangle will be ∠B = 71°.

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

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?"

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:

a) The difference between the temperatures is 5°c.

b) We will see that at midday, the temperature is 12°C.

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.

The solutions to the equation -2x² + y = -5 and y=-3x² +5 are  (√2,-1) and (-√2-1) option third is correct.

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

We have given expressions:

-2x² + y = -5 ..(1)

y=-3x² +5 ...(2)

From the equation (2) take the value of y and plug it in the equation (1)

-2x²-3x²+5 = -5

-5x² = -10

x = ±√2

Plug this value in the equation (2), we get value of y:

y = -1

Thus, the solutions to the equation -2x² + y = -5 and y=-3x² +5 are  (√2,-1) and (-√2-1) option third is correct.

The radius of the given cylinder of volume 847π yds³ and height of 7 yards is 11 yards

From 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.

We have :

Substituting the values :

>> V = 3.14 × (5)^2 × 6

>> V = 3.14 × (5 × 5) × 6

>> V = 3.14 × 25 × 6

>> V = 3.14 × 150

>> V = 471

Volume of cylinder = 471 units .
