Answer:

[tex]<174\frac{4}{9}[/tex] hopes this helps :D

Step-by-step explanation:

The solution is s > 174 4/9

The inequality equation is s > 174 4/9 and it will take 174 4/9 seconds for the hot air balloon to reach below 215 feet

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is given by

Let the total altitude of the hot air balloon be = 1000 feet

Now , the hot air to reach below 215 feet , the hot air balloon should descend a total of = 1000 - 215 feet

So , the value of hot air balloon should descend = 785 feet

And ,

The rate at which the hot air balloon descends = 4 1/2 feet per seconds

So , the number of seconds s for the hot air balloon to reach an altitude more than 785 feet is given by the inequality equation A

where ( 4 1/2 ) x s > 785

On simplifying the equation , we get

( 4 1/2 )s > 785

( 9/2 ) s > 785

Multiply by 2 on both sides of the equation , we get

9s > 1570

Divide by 9 on both sides of the equation , we get

s > 174 4/9

Therefore , the value of A is s > 174 4/9

Hence ,

The inequality equation is s > 174 4/9 where s is the number of seconds

Answer:

ok, but i can't even see nothing, though ;-;

Answer:

6x - 18

Step-by-step explanation:

2x - 6 + 4x - 12 = 6x - 18

First, distribute the 4 and then combine the like terms to get 6x - 18.

Answer:

x=-2

Step-by-step explanation: First we can multiply 4 times anything in the parenthesis to get rid of it.

(2x-6)+4(x-3)

(2x-6)+4x-12

Then we combine like terms.

(2x-6)+4x-12

6x-6-12

6x-18

Finally we divide both sides by 6.

6x-18

6x/6-18/6

x=-2

Step-by-step explanation:

a. to find the amount of canada covered in fresh water, multiply 9970000 by 0.08 to get 797600km

b. the amount not covered by fresh water is 9970000-797600 which equals 9172400 km

c. multiply area of canada by 0.23 which is 2293100 km

just in case you might want to double check the zeros to make sure i did it right

Answer:

a. 797,600 km²

b. 9,172,400 km²

c. 2,293,100 km²

Step-by-step explanation:

To find a percent of a number, multiply the percent by the number. First, change the percent into a decimal number by moving the decimal point of the percent 2 places to the left. For example, 42% = 0.42; 7% = 0.07

Part a.

8% of 9,970,000 km²

Step 1. Multiply the percent by the number

8% of 9,970,000 km² = 8% × 9,970,000 km²

Step 2. Change the percent into a decimal number by moving the decimal point of the percent 2 places left.

8% of 9,970,000 km² = 8% × 9,970,000 km² = 0.08 × 9,970,000 km²

Step 3. Use a calculator or long division to do the multiplication.

0.08 × 9,970,000 km² = 797,600 km²

Answer: a. area covered in fresh water is 797,600 km²

Part b.

Subtract the area of part a. from the total area of Canada.

9,970,000 km² - 797,600 km² = 9,172,400 km²

Answer: b. area not covered in fresh water is 9,172,400 km²

Part c.

Tundra is 23% of total area.

23% of 9,970,000 km²

Step 1. Multiply the percent by the number

23% of 9,970,000 km² = 23% × 9,970,000 km²

Step 2. Change the percent into a decimal number by moving the decimal point of the percent 2 places left.

23% of 9,970,000 km² = 23% × 9,970,000 km² = 0.23 × 9,970,000 km²

Step 3. Use a calculator or long division to do the multiplication.

0.23 × 9,970,000 km² = 2,293,100 km²

Answer: a. area covered in tundra is 2,293,100 km²

Answer:

ll available yellow and red flowers at the two businesses

Population: all available flowers at the two businesses

Step-by-step explanation:

The sample and population should be sample represents all yellow and red flowers while the population represents all flowers.

The entire group about whom you want to make conclusions is referred to as a population. The particular group from which you will gather data is known as a sample. The sample size is always smaller than the population as a whole. A population in research doesn't usually refer to humans.

An entire group from which a conclusion should be derived is referred to as a population. The sample, on the other hand, refers to the population from which the data is drawn.

So based on this, we can say that the sample represents all yellow and red flowers while the population represents all flowers.

Answer:

Step-by-step explanation:

-1 to 0 is divided in four parts.

similarly 0 to 1 is divided in four parts

so each fraction on either side is 1/4 onthe right of 0 and -1/4 on the left of 0.

A is 2 parts on the right of 0,A=2×1/4=1/2=0.5

Step-by-step explanation:

Functions must have only one y-value for an x-value.

The special right triangle is the right triangle that have acute angle values

that simplify the process of finding its dimensions.

The correct values are;

1. The angle the ladder makes with the ground, is approximately 66.93°

2. The length of YZ is approximately 19.18 ft.

3. CB = 7 ft. and AB = 7·√3 ft.

Reasons:

1. The length of the ladder = 15 ft.

Height of the ladder above the ground, h = 13.8 ft.

Required:

The angle the ladder makes with the ground.

Solution:

The angle the ladder makes with the ground is given by the equation;

[tex]sin(\theta) = \dfrac{Length \ of \ the \ ladder}{Height\ of \ the \ ladder \ above the \ ground} = \dfrac{13.8}{15} = 0.92[/tex]

[tex]\theta = arcsin\left(0.92 \right) \approx 66.93^{\circ}[/tex]

2. The given parameters are;

XY = 11

∠Z = 35°

YZ = Required

In a right triangle, the side facing the acute angle is a leg of the triangle.

Therefore;

XY is the opposite side to ∠Z

[tex]sin(\angle Z) = \dfrac{XY}{YZ}[/tex]

Which gives;

[tex]sin(35^{\circ}) = \dfrac{11}{YZ}[/tex]

[tex]YZ= \dfrac{11}{sin(35^{\circ}) } \approx 19.18[/tex]

YZ ≈ 19.18 ft.

3. AC = 14 ft.

∠A = 30

Required:

The length of the other two sides

Solution:

Where by AC is the hypotenuse side, we have;

CB = AC × sin(∠A)

Therefore;

CB = 14 × sin(30°) = 7

CB = 7 ft.

AB =  AC × cos(∠A) = 14 × cos(30°) = 7·√3

Answer:

58

Step-by-step explanation:

You would have to turn 7 1/4 into a whole fraction.

Do,

7 * 4 = 28

28 + 1 = 29

Your new fraction would be,

29/4

Now you have to make them equal denominators with 1/8.

Lets see,

Now multiply 4 * 2 is 8.

So multiply 29 times 2.

Which is 58.

Your new fraction is,

58/8

So therefore you would have 58 pieces.

Answer: 150 m, 5.305*10^-5 kW/m^2, No

Step-by-step explanation:

See attachment, hope this helps

Using the radiation intensity formula we will have to:

a) [tex]150 m[/tex]

b) [tex]5.305*10^{-5} kW/m^2[/tex]

c)No

From the data informed, we have:

[tex]h=150m\\P=40KW[/tex]

Using the given formula and performing some mathematical operations:

[tex]I=\frac{12Psin^2(\theta)}{32(\pi)r^2} \\I= \frac{12(40)(R/r)^2}{32(\pi)r^2} \\= \frac{15R^2}{r^2\pi } \\= \frac{15R^2}{(R^2+150^2)^2\pi} \\[/tex]

deriving the given equation, we will have:

[tex]=\frac{(R^2+150^2)^22R-R^2(2(R^2+150^2))2R}{(R^2+150^2)^2}[/tex]

So from this equation we have that the answer of the letter A corresponds:

[tex]R=150[/tex]

For letter B we will have to develop this equation:

[tex]I= 5.30X10^{-5}[/tex]

As for the letter C, when converting the value found, it should give 200 microwatts, which is false.
