How many times in the 30 minutes graphed is the temperature exactly 40 degrees? (Brainlist!!)

Answer:

336 cm²

Step-by-step explanation:

1 rectangle 24 cm by 12 cm

1 triangle with base 12 cm and height 8 cm (combining the two small triangles into 1 larger triangle)

SA = 24 cm * 12 cm + 12 cm * 8 cm / 2

SA = 288 cm² + 48 cm²

SA = 336 cm²

Answer:

The radius of the cylinder is 3 inches.

Step-by-step explanation:

For any given cylinder, the volume can be expressed as:

volume = [tex]\pi[/tex][tex]r^{2}[/tex]h

where r is the radius of its circular surface, and h is its height.

Given that: volume = 54π cubic inches, and the height = 6 inches.

then,

54[tex]\pi[/tex] = [tex]\pi[/tex] x [tex]r^{2}[/tex] x 6

54[tex]\pi[/tex]  = 6[tex]\pi[/tex][tex]r^{2}[/tex]

[tex]r^{2}[/tex] = [tex]\frac{54\pi }{6\pi }[/tex]

   = 9

r = [tex]\sqrt{9}[/tex]

r = 3

The radius of the cylinder is 3 inches.

Answer:

52/6 = 8 and 2/3

Step-by-step explanation:

52 divided by 6 is 8 and 2/3

6 multiplied by 8 is 48

52-48 is 4

so 52/6 is 8 remainder 4

or you can divide 4 by 6

4/6 = 2/3

so it can also be 8 and 2/3

52 divided by 6 as a fraction in its simplest form is 8 2/3.

To express 52 divided by 6 as a fraction, you simply write it as:

52 / 6

To simplify the fraction, find the greatest common divisor (GCD) of the numerator (52) and the denominator (6), and then divide both the numerator and denominator by the GCD.

The GCD of 52 and 6 is 2.

Divide both the numerator and denominator by 2:

(52 / 2) / (6 / 2)

This simplifies to:

26 / 3

now, we have,

Divide 26 by 3:

26 ÷ 3 = 8 with a remainder of 2

The whole number part is 8, and the remainder (2) becomes the new numerator.

The denominator remains the same.

So, 26/3 as a simplified mixed number is: 8 2/3

So, 52 divided by 6 as a fraction in its simplest form is 8 2/3.

Answer:

[tex]F'G' = 7[/tex]

Step-by-step explanation:

Given

[tex]F = (-2,4)[/tex]

[tex]G = (-2,-3)[/tex]

Required

Distance of F'G'

The transformation that give rise to F'G' from FG are:

The above transformations are referred to as rigid transformation, and as such the side lengths remain unchanged.

i.e.

[tex]F'G' = FG[/tex]

Calculating FG, we have:

[tex]FG = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

Where:

[tex]F = (-2,4)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]G = (-2,-3)[/tex] --- [tex](x_2,y_2)[/tex]

[tex]FG = \sqrt{(-2 - -2)^2 + (4 - -3)^2}[/tex]

[tex]FG = \sqrt{(0)^2 + (7)^2}[/tex]

[tex]FG = \sqrt{0 + 49}[/tex]

[tex]FG = \sqrt{49}[/tex]

Take positive square root

[tex]FG = 7[/tex]

Recall that:

[tex]F'G' = FG[/tex]

[tex]F'G' = 7[/tex]

Answer:

f(-1)= 4

Step-by-step explanation:

Just plug -1 into all Xs

and split it into 2 seperate problems for the time being

[9 times (-1)^2] + [2(-1)-3]

-1 squared is positive 1  times the 9 is just 9

Plus  2 times -1 is -2 minus 3 is -5

combine the two seperate problems you have

9-5 the subtract and

f(-1)= 4

You are trying to find the cube root of a number. Because the number is being multiplied by itself 3 times over, only a negative number could be a cube root of another negative number

Answer:

3:00

Step-by-step explanation:

If the minute hand is pointing straight up, it means that the time is at an exact hour (ex. 1:00, 2:00, not 1:30, etc.).

If the angle between the hour and the minute hand is 90 degrees, then we know that the time is either 3:00 or 9:00.

However, because the time must be between 1:00 and 5:30, it must be 3:00.

Step-by-step explanation:

Answer:

Z= 180 X = 95   y= 147

Step-by-step explanation:

Z=180 because it is a line and when it is a line it = 180 degrees

for X you want to first find the angle of the other triangle and when you do you subtract that # from 180 because those 2 angles make a line

to find that angle next to X is...

180- (the other 2 angles in the triangle)

180- 45- 50

180-95

85 degrees

now do

180-85

95 degrees   -- this is what X =

now you want to find the angle that is left in one triangle

so do

180- 95- 52

180- 147

33 degrees -- the angle that was missing

to find Y do...

180- 33

147 degrees -- this is what Y =

Answer:

Step-by-step explanation:

Ok so first, we must figure out what 1 once costs. This can be done by divideing 4.48(cost) by 14(weight).

You should get 0.32.

Now just multiply by 8 and you should get your answer. This answer is 2.56.

Answer:

2.56

Another way this can be done is dividing 8(second weight) by 14(first weight) which will get you the difference. This is 0.5714 blah blah blah goes on for a long time. Now, take this number and multiply it by the 4.48(first cost). This should get you 2.56.

2.56

Answer:

- The neighbor that has the most amount of fence to put up is: Neighbor A.

- The neighbor that has the least amount of fence to put up is: Neighbor C.

Step-by-step explanation:

To calculate the amount of fence that Neighbor A has to put up, you need to add the following distances:

Convert yards to feet (Remember that :

To calculate the amount of fence that Neighbor B has to put up, you need to use the formula for calculate the circumference of a circle:

Where r is the radius.

In this case, the radius is:

Substituting, you get:

To calculate the amount of fence that Neighbor C has to put up, you need to add the following distances:

Therefore, the neighbor that has the most amount of fence to put up is: Neighbor A.

The neighbor that has the least amount of fence to put up is: Neighbor C.
