Answer:

84.4

Step-by-step explanation:

done

Volume of a right circular cone is  84.39 m³

The amount of space occupied by a three-dimensional figure as measured in cubic units.

Given:

height = 12.4 m. base diameter= 5.1 m, radius= 5.1/2 m

Volume of right circular cone= 1/3* π* r²*h

                                                = 1/3*3.14* 2.55*2.55*12.4

                                               = 84.39 m³

Hence, the volume of right circular cone is 84.39 m³

Answer:

Option B

Step-by-step explanation:

By applying Pythagoras theorem in the given right triangle,

(Hypotenuse)² = (leg 1)² + (leg 2)²

Now substitute the measures of each side in the formula,

(13)² = x² + (12)²

169 = x² + 144

x² = 169 - 144

x² = 25

x = √25

x = 5

Therefore, Option B will be the correct option.

Answer:

The ball reaches 44 ft above the ground after 4 sec.

Step-by-step explanation:

Set h(t)=-16t^2+300 equal to 44 feet and solve for time, t.  Indicate exponentiation with " ^ "

-16t^2 + 300 = 44 becomes

-16t^2 + 256 = 0, or 16t^2 = 256.  Then, taking the square root of both sides, we get:

4t = 16, or t = 4 sec.  The ball reaches 44 ft above the ground after 4 sec.

The ball will take 4 seconds.

A quadratic equation, or simply "quadratics," is a polynomial equation with a degree of two as its highest. This is how it is expressed:

a x² + b x + c = 0 where x is the unknown variable and the constant terms are a, b, and c.

Given equation of height h(t) = -16t² + 300...…..(1)

where h is height in feet and t is time in seconds,

and height at t = 0 is 300 feet

when ball is 44 feet above ground then time is,

put h = 44 in equation 1

44 = -16t² + 300

16t² = 300 - 44

t² = 256/16

t = √16

t = 4

Hence time taken by ball is 4 seconds.

Step-by-step explanation:

Given

See attachment for grid

Required

Which point is on Veronica's path

On the attached grid, I plotted each of the coordinate pair (i.e the given options, A to D) on the grid.

By observation. we can see that:

A is on the vertical line (y intercept)

B is on the second quadrant

C is just few points to the left of the given path

D represents Verlonda's house

Hence, the required coordinate pair is: (3.8)

Answer:

38

Step-by-step explanation:

The area of a kite is equal to half the product of the diagonals

To find the area we must first find the measures of the diagonals

short diagonal = 2 + 2 = 4

longer diagonal = 8 + 11 = 19

We then calculate the area by multiplying the two diagonals together and then dividing that by 2

A = 19 * 4 = 76

76 / 2 = 38

Hence, the area of the kite is 38m²

38m².

Answer:

Solution given;

diagonal 1=8+11=19m

diagonal 2=2+2=4m

the area of a kite =½*diagonal 1*diagonal 2

=½*4*19=38m²

The area of kite is 38m².

Answer:

b.area of one triangular faces =9m²

Answer:

0.5

Step-by-step explanation:

The formula is I= prt

I= 60

P= 2000

r= 1.5%

60= 2000×1.5/100×t

60= 30t

t= 30/60

= 0.5

Hence the time required is 0.5 years

Answer:

x≥−3

Step-by-step explanation:

Let's solve your inequality step-by-step.

2x+3/ −3 ≤1

Step 1: Simplify both sides of the inequality.

−2/ 3 x−1≤1

Step 2: Add 1 to both sides.

−2/ 3 x−1+1≤1+1

−2/ 3 x≤2

Step 3: Multiply both sides by 3/(-2).

( 3/ −2 )*( −2/ 3 x)≤( 3/ −2 )*(2)

x≥−3

Answer:

15

Step-by-step explanation:

The pertinent general formula for this arithmetic progression is

a(n) = a(1) + d(n - 1), where d is the common difference.  That difference is d = 4.

Here, a(n) = -5 + 4(n -1)

Therefore, a(6) = -5 + 4(5) = 15

Answer:

It is 15.

Step-by-step explanation:

Alright, first lets find the pattern. Since its a arithmetic sequence, it has something to do with adding/subtracting.

With the values, -5, -1, and 3. Notice something about them? -1 is 4 more than -5 & 3 is 4 more than -1. There's a pattern! The pattern is that for every new term, it is 4 more than the one before it.

With this, we can make a table to find the 6th term!

(Given)

1st Term: -5

2nd Term: -1

3rd Term: 3

Now, continue adding 4 to each term...

4th Term: 7

5th Term: 11

6th Term: 15

For the 6th term, it has been found that the answer's 15.
