Answer:

3h³k² + 18h³k + 27h³

Step-by-step explanation:

Given

3h³(k + 3)² ← expand factor using FOIL

= 3h³(k² + 6k + 9) ← distribute parenthesis

= 3h³k² + 18h³k + 27h³

2.45 N

weight = mass x 9.8 m/s^2

Answer:

Here,

Mass ( m ) = 250g = (250/1000) kg =0.25 kg

g =9.8 m/s^2

Weight ( W ) = ?

We know that,

Weight ( W ) = m*g [Where g is acceleration due to gravity]

                   = (0.25*9.8) N

                    = 2.45 N

Answer:

8:6

Step-by-step explanation:

If 8 out of 14 students are boys then the remaining number of students must be girls

So

14-8= 6

There are 6 girls out of the 14

So as a ratio of boys to girls

8:6

Answer:

8 : 6 <or> 4 : 3

Step-by-step explanation:

8 : 6 <or> 4 : 3

Since there are 8 boys out of 14, if you minus them , the answer will be the number of girls out of 14.

Answer:

The distance to the top of the balloon is approximately 33.977 meters

Step-by-step explanation:

The (horizontal) distance from the hot air balloon from the observer, l = 30 m

The angle of elevation to the top of the balloon, θ = 28°

With the balloon standing upright, the distance to the top of the balloon, d, the height of the balloon, h and the horizontal distance to the balloon, l, form a right triangle, where;

d = The hypotenuse side

l = The leg adjacent to the reference (given) angle,

h = The leg opposite to the given angle, θ

By trigonometric ratios, we have;

[tex]cos\angle X = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}[/tex]

From which we get;

[tex]cos\angle \theta = \dfrac{l}{d}[/tex]

[tex]cos(28^{\circ}) = \dfrac{30 \ m}{d}[/tex]

[tex]d = \dfrac{30 \ m}{cos(28^{\circ}) } \approx 33.977 \, m[/tex]

The distance to the top of the balloon, d ≈ 33.977 m

Answer:

p=1

Step-by-step explanation:

2/5 + p = 4/5 + 3/5p

Multiply each side by 5 to clear the fractions

5(2/5 + p) = 5(4/5 + 3/5p)

2 +5p = 4 + 3p

Subtract 3p from each side

2+5p-3p = 4+3p-3p

2+2p = 4

Subtract 2 from each side

2+2p -2 = 4-2

2p =2

Divide by 2

2p/2 = 2/2

p=1

Answer:

[tex]-180^{\circ}[/tex]

Step-by-step explanation:

Lines form 180 degrees on either side. The negative sign simply implies direction (clockwise instead of counter-clockwise), which is negligible as 180 is exactly half of 360 so you'd form the same line.

Answer:

-180 because its through 0

Answer:

ans: x= 1/(a-b)

Step-by-step explanation:

given equation is

ax = bx + 1

to isolate x , take bx to left side

or,

subtract bx on both sides , I.e

ax - bx = 1

x( a- b) = 1

x = 1/(a- b)

Given:

The area of a flower garden is 60 m².

One third of it was used for growing roses and the remaining area was divided into two equal parts.

To find:

The area of each remaining part.

Solution:

It is given that the area of a flower garden is 60 m² and one third of it was used for growing roses. So, the remaining part is:

[tex]\text{Remaining}=60-\dfrac{1}{3}\times 60[/tex]

[tex]\text{Remaining}=60-20[/tex]

[tex]\text{Remaining}=40[/tex]

The remaining area was divided into two equal parts. So, the area of each remaining part is:

[tex]\text{Area of each remaining part}=\dfrac{40}{2}[/tex]

[tex]\text{Area of each remaining part}=20[/tex]

Therefore, the area of each remaining part is 20 m².

The solution is:

48.6 quart of fertilizer is the total fertilizer will Alan need for his two fields.

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

The directions say to use 4/5 of a quart of fertilizer for each acre of land.

Alan has two fields,

Field 1

22 1/2 acre of land

1 acre of land = 4/5 quart

22 1/2 acre of land = x

Cross Multiply

x = 22 1/2 × 4/5

x = 45/2 × 4/5

x = 18 quart of fertilizer

Field 2

38 1/4 acres of land

1 acre of land = 4/5 quart

38 1/4 acre of land = x

Cross Multiply

x = 38 1/4 × 4/5

x = 153/4 × 4/5

x = 30.6 quart of fertilizer

The total fertilizer that Alan will need for his two fields is calculated as:

18 quart of fertilizer + 30.6 quart of fertilizer

= 48.6 quart of fertilizer

Hence, 48.6 quart of fertilizer is the total fertilizer will Alan need for his two fields.

Step-by-step explanation:

wall 25×12=300

2 walls = 600

wall2 20×12=240

2 wall2= 480

600+480= 1080 sq ft

The number of gallons that must be bought to cover a room with two 25' by 12' walls and two 20' by 12' walls is 3.6 gallon

"Area of rectangle is the region occupied by a rectangle within its four sides or boundaries. The area of a rectangle depends on its sides."

Given,

A gallon of paints covers 300 square feet.

Area of the first two walls is [tex]2*25*12[/tex] = 600 square feet

Area of the second two walls is [tex]2*20*12[/tex] = 480 square feet

Total area of the room is = 480+600 = 1080 square feet

The paint required for 1 feet is = 1/300

So, the paint required for 1080 feet is = 1080/300 =3.6

Hence, the paint required to cover the entire room is = 3.6 gallon

Answer:

(a). We are 98% confident that the proportion of adults in the United States who believe it is more enjoyable to be married than single is between 0.7250 and 0.7770.

Step-by-step explanation:

According To the Question,

Answer:

w = 5.2

Step-by-step explanation:

4(2.25w + 3.1) - 2.75w = 44.9

9w + 12.4 - 2.75w = 44.9

6.25w + 12.4 = 44.9

6.25w = 32.5

w = 5.2

4(2.25w+3.1)-2.75w=44.9

9w+12.4-2.75w=44.9

9w-2.75w+12.4=44.9

44.9-12.4=32.5

9w-2.75w=32.5

6.3w/6.3=32.5/6.3
