Answer:

Volume of a cylinder, V = πr^2h

but r= d/2

therefore, Vol = π(d/2)^2h

from the parameters given,

Vol = π(18/2)^2h

=81πh

Answer:

He burrows 6 holes in 2 minutes which means that he can burrow 3 holes in 1 minute.

To determine how many he can burrow in 7 minutes, you would multiply the

unit rate of 3 holes in 1 minute by 7.

He would burrow 21 holes in 7 minutes.

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

(1/2)(6x-2) - 3(x-1)

take the (1/2) and distribute it to the 6x and the 2

(3x-1) - 3(x-1)

next, distribute the 3 to the x and the 1

(3x-1) - (3x-3)

then you simplify

3x-3x cancels

-1 - -3 is the same as -1 +3

so you get 2

Answer:

Step-by-step explanation:

h= 19 yards, r=7yards, v=?,Π= 3.14

Vol. Of a cone = 1/3×h×Π×r²

V= 1/3×19×3.14×7²

V= 2923.34/3

V=974.45

To the nearest hundredth

V=974cm³

Answer:

y=-2x+5; slope is -2

Step-by-step explanation:

slope is rise/run. we can see it rises 2 and goes left one which would give us rise/run=2/-1=-2. that is our slope.

using y=mx+b to write the equation, m is slope and b is the y-int.. we can see that the y-int. is (0,5). we can plug 5 into b.

plugging b and m in we can get the equation: y=-2x+5

Answer:

B.

Answer:Algebra Questions, for Grade 10, on simplifying, factoring, evaluating expressions and solving equations are presented along with their answers

Step-by-step explanation:

I do not know if this helps or not but here you go!

Step-by-step explanation:

The line A, the slope is +2

And line B the slope is n-1

Answer:

For A;

x1 = -2, y1 = -3, x2 = 3, y2 = 7

Gradient = (y2 - y1)/(x2 - x1)

= (7 - (-3))/(3 - (-2))

= 10/5 = 2.

For B;

x1 = 7, y1 = -2, x2 = -2, y2 = 7

Gradient = (y2 - y1)/(x2 - x1)

= (7 - (-2))/(-2 - 7)

= 9/-9 = -1.

Answer:

Y=4x-3

Explanation: If we look 2 = 5 We can do 4(2)= 8 -3 = 5 So that the answer and 4(4)= 16-3 = 13 so these are the Y so this is the answer!

Answer:

Step-by-step explanation:

All angles in a triangle add up to 180º, so we can make this equation.

7x-2+5x-10+4x=180

Combine like terms

16x-12=180

Add 12

16x=168

Divide

x=16.5

Answer:

Part B= (7.5 years, 2.25ish dollars) or about (7,2)

Step-by-step explanation:

im sorry i couldn't answer part b

Answer: m∠T = 48°

ΔMAT has MA = MT

=> ΔMAT is a isosceles triangle at M

=> ∠A = ∠T = (180° - ∠M)/2

=> x + 20  = (180 - 3x)/2

⇔ 2x + 40 = 180 - 3x

⇔ 5x = 140

⇔ x = 140/5

⇔ x = 28

=> ∠A = ∠T = 28 + 20 = 48°

Volume of pyramid with square base is 1057.54 m³

Step-by-step explanation:

We are given:

Length of base of pyramid = 14.4 m

Height of pyramid = 15.3 m

We need to find:

Volume of pyramid with square base

The formula used is: [tex]Volume=\frac{1}{3}\times a^2 \times h[/tex]

Where a = base of pyramid and h is height

Putting values and finding volume

[tex]Volume=\frac{1}{3}\times a^2 \times h\\Volume=\frac{1}{3}\times (14.4)^2 \times (15.3)\\Volume=\frac{1}{3}\times 207.36 \times 15.3\\Volume=1057.54 \ m^3[/tex]

So, Volume of pyramid with square base is 1057.54 m³

Answer:

1057.5

6x-6

Answer: a

Step-by-step explanation:

multiply each answer by 10

Answer:

I believe the answer would be 6

Step-by-step explanation:

Area = length x width

4 x 3 = 12

12/2= 6 because only half of the rectangle is shaded

Answer:

6x²- x -12

Step-by-step explanation:

(2x-3)(3x + 4)

or, 2x(3x + 4) - 3(3x + 4)

or, 6x² + 8x - 9x - 12

= 6x² - x - 12

Answer:

6x²-x-12 that is my answer but I dont know if it is correct

Answer: y=4x-2

Step-by-step explanation:

Since you are looking for y-intercept, the point has to be on the vertical line and the slope is 4 so it has to go up 4 to the right 1

3 to the power of 4 is 81 times 3 is 243

Answer:

3^5

Step-by-step explanation:

Answer:

Obtuse

Step-by-step explanation:

Answer: scalene, and obtuse

Step-by-step explanation: All of the sides are different lengths so that makes it a scalene triangle. On the picture it also shows that one of the angles is 107 degrees. Since 107 is larger than 90, it is an obtuse triangle.

Answer:

The x-intercept is (7,0), and the y-intercept is (0,-35).

Step-by-step explanation:

The x-intercept has a y-coordinate of 0, since it is only because of that can the x-intercept touch the x-axis. Hence, once we plug y = 0 into 5x - y = 35:

5x - 0 = 35

5x = 35

x = 7.

Hence, the x-intercept is (7, 0).

Consequently, the y-intercept can be found using the same methods. Knowing the y-intercept has a x-coordinate of 0, we can plug that in to find:

5(0) - y = 35

0 - y = 35

y = -35

Hence, the y-intercept is (0,-35).
