Answer:B; 4.35 • 10/4

Step-by-step explanation:

Answer:

It's volume

Volume = πr²h

[tex] \tt \: volume = \dfrac{22}{7} \times 3 {}^{2} \times 8[/tex]

[tex] \tt volume \: = \frac{22}{7} \times 9 \times 8[/tex]

[tex] \tt \: volume = \dfrac{22}{7} \times 72[/tex]

[tex] \tt \: volume \approx \: 226.194[/tex]

Answer:

given. require. solution

r=3. v=? v=πr²h

h=8. v=3.14×3²×8

3.14×9×8

Answer: C :79.5

Step-by-step explanation:

Since both triangles are congruent the angles are also congruent. P the measure we are trying to find is congruent to M since they’re equal it should look like this

5x-19 = 3x+20.4

5x = 3x+ 39.4

2x = 39.4

X= 19.7

to find the measure of angle P plug in X to its equation so

3x + 20.4

3 (19.7) + 20.4

= 79.5

Step-by-step explanation:

Answer:

-2 will be 2 times to the left of zero and -6 would be 6 spaces to the left of zero.

Step-by-step explanation:

Alex takes 15 min to travel 18km

=> 1 hour amd 45 min to travel 18 * 7 = 126km.

Hence Roy travel 126km * (5/4) = 157.50km.

Answer:

So first look at the symbol. It must be less than or equal to 17.

By elimination A is 20.5 which is wrong

B is -16.5 by abs =16.5

C is -17.5 by abs = 17.5

D is 12.5

So B and D are possible solutions..

Answer:

13

Step-by-step explanation:

The term is in an arithmetic progression.

That means there is 6 between each term and the next one.

Givens

a = -30

d = 6

last term an = 42

Formula

L = a + (n - 1)*d

Solution

42 = -30 + (n -1 )*6               Add 30 to both sides

42+30 = (n - 1) * 6                Combine the terms on the left.

72 = (n - 1)*6                        Divide both sides by 6

72/6 = n - 1

12     = n - 1                          Add 1 to both sides

12 + 1 = n

n = 13

I'm not quite 'out there in the real world' but whenever I'm limited on money and whatnot, instead of trying to go ahead and add it all up by the exact price I'll round it up to the nearest dollar. Sometimes I'll even round it up two dollars. If it's something like '$25.98', I'll figure $27.00. That always helps me not spend as much.

Making a list and strictly following the list helps as well. I wouldn't try to spend money on things unessential, or things that you really don't have the money for.

Answer:

The equation of the line is y = 3x - 11.

Step-by-step explanation:

We are given the equation of a line:

[tex]\bullet \ \ \ y = 3x -2[/tex]

We are also given a point at which the line passes through.

[tex]\bullet \ \ \ (4, 1)[/tex]

With parallel lines, it is important to note:

We can use the point-slope equation to find the equation of the line:

[tex]\displaystyle y-y_1 =m(x-x_1)\\\\y - 1 = 3(x - 4)\\\\y - 1 = 3x - 12\\\\y - 1 + 1 = 3x - 12 + 1\\\\y = 3x - 11[/tex]

Therefore, the line that is parallel to y = 3x - 2 and passes through the point (4, 1) is y = 3x - 11.

50(5)+100= B

 250+100=350

Answer:

B. x = -6

Step-by-step explanation:

A line with the equation, y = ¼, is a horizontal line. Therefore, the line that is perpendicular to it would be a vertical line, which can be represented by the equation, x = a. Where, a is the x-value or the point where the vertical line intersects the x-axis. This x-coordinate remains the same for every point on the vertical line.

Thus, since the perpendicular line passes through (-6, -9), therefore, the value of a = -6.

Thus, the equation of the perpendicular line would be:

x = -6
