Answer:8

Step-by-step explanation:

Answer:

(10/3, 1)

Step-by-step explanation:

Give the coordinates of the point that would divide AB into a ratio of 2:1. A(4,4) B(2,-5)

The formula for calculating the coordinate of a point divided in the ratio a:b is expressed as;

X = ax1+bx2/a+b

Y = ay1+by2/a+b

Given the coordinates A(4,4) B(2,-5) divided in the ratio 2:1

X = 2(4)+1(2)/2+1

X = 8+2/3

X = 10/3

Similarly;

Y = 2(4)+1(-5)/2+1

Y = 8-5/3

Y = 3/3

Y = 1

Hence the required coordinate is (10/3, 1)

Answer:

2/10 20%

Step-by-step explanation:

The line that is parallel to this line will have the same slope of this line, as the two will never intersect. They will run side by side. The line y = 2x - 5 is written in slope-intercept form, which is y = mx + b. The value of m represents the slope, and in this equation m = 2. Therefore, the line we are looking for will have a slope of 2 also.

That line should also be in slope-intercept form. We now know the value of m, but we also know the value of x and y. The ordered pair (8, 10) is a point on the line, and every ordered pair is in the form (x, y). Therefore, x = 8 and y = 10. We can plug those values into y = mx + b, along with m = 2. That gives us:

10 = 2(8) + b We need to solve for b.

10 = 16 + b

b = -6

Answer:

16√3 cm³

Step-by-step explanation:

The volume of a triangular prism is given as:

V = (1/3)B*h

Where B is the area of the base and h is the height of the prism.

Given that B = 12√3. The height fro the diagram is BC.

Since ∠BAC = 30° and ∠BCA = 90°, we can find BC using trigonometric identity.

tan(30) = BC / AC

but AC = 4√3, hence:

tan(30) = BC / (4√3)

BC = 4√3(tan 30)

BC = 4

V = (1/3)B*h = (1/3)B* BC = (1/3) * 12√3 * 4 = 16√3 cm³

Answer:V= 1526.8m3

Step-by-step explanation: pi (9)2(6)

A cylinder is a three-dimensional structure formed by two parallel circular bases. The volume of a cylinder, in cubic m, with a height of 6m and a base diameter of 18m is 1526.814.

A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centres overlap each other to form a right cylinder.

Given the height of the cylinder is 6m, while the base diameter is 18m. Therefore, the volume of the cylinder can be written as,

Volume of cylinder = (π/4)×d²×h = (π/4)×18²×6 = 1526.814m³

Hence, the volume of a cylinder, in cubic m, with a height of 6m and a base diameter of 18m is 1526.814.

Answer:

No it is Not Equivalent

Step-by-step explanation:

5x and x + 5 are NOT equivalent because 5x would be 5 times x or 5(x) but for x + 5 it is just 5 + x they will not be the same value either.

Answer:

B. function 13 meters per second

Step-by-step explanation:

Answer:

B) Function A; 14 mps

Step-by-step explanation:

Function B has a speed of 13/s

If you look at Function A and divide the right column by the corresponding values in the left column, you get 14 every time. That is the rate of Function A.

14>13.. so Function A is faster

=6.8+0.85

=$7.65

Answer:

246 cm

Step-by-step explanation:

So I solved for the two triangles, 6x8=48/2=24, since there are 2, I multiplied by 2 to get 48 (Could've kept it just as 48 but it's good to keep the habit of dividing by 2 to get area of a triangle).  Then I did 6x9 for the front rectangle to get 54, and then solved for the right and back rectangle by doing 9x8 to get 72, 72x2=144

144+48+54= 246
