Answer:

This means the store room is 19.15ft up

Step-by-step explanation:

The set up of the question will form a right angle triangle.

The length of the ladder will be the hypotenuse of the triangle and the angle the ladder forms will be the angle of elevation. This angle of elevation will face the opposite side of the triangle which is the height of the storeroom directly.

Using the SOH CAH TOA trigonometry identity,

According to SOH;

Sin∅ = opposite/hypotenuse

∅ is the angle the ladder forms

sin50° = x/25

x = 25sin50°

x = 19.15ft

This means the store room is 19.15ft up

Answer:

Step-by-step explanation:

You have a 10 gallon jug and a 3 gallon jug and need exactly 5 gallons of water.

This what you do:

- Fill the 3 gallons jug full and pour into the 10 gallons keg

- Repeat the above a second time making a total of 6 gallons of water in the 10 gallons jug.

- Fill the 3 gallons jug a third time and pour into the 10 gallons jug making 9 gallons

- Fill the 3 gallons jug the fourth time and pour into the 10 gallons jug till full leaving 2 gallons of water remaining in the 3 gallons jug.

- Then empty out the 10 gallons jug and pour the 2 gallons of water in the 3 gallons jug into the 10 gallons jug.

- Then, fill the 3 gallons jug again and pour into the 10 gallons jug holding the 2 gallons of water making a total of 5 gallons of water in the 10 gallons jug.

Hope, that helps!!!

$1,440; Possible work: Since 300 4 5 5 60, Kendra gets paid $60 per day: 60 3 24 5 1,440. So, she gets paid $1,440 for working 24 daysStep-by-step explanation:

HOPE THIS HELPS

Answer:

1440 = x

Step-by-step explanation:

We can use a ratio to solve

300 dollars      x dollars

----------------- = ------------

  5 days               24 days

Using cross products

300*24 = 5x

Divide each side by 5

300*24/5 = 5x/5

1440 = x

Answer:The length of the third side 2.5.

Step-by-step explanation:

We already know the length of two side but we don’t know the length of one side so we will represent it by b and we know they three lengths add up to 12b+5.

4b + 3b+15 +b =12b + 5

Solve for b.

8b +15=12b +5

-8b -8b

15+4b +5

-5 -5

4b/4=10/4

B=2.5

So the length of the third side is 2.5

4(2.5) + 3(2.5)+15+2.5=12(2.5)+5

35=35

Answer:

0.84

Step-by-step explanation:

You got number 38 wrong. It should be 0.625

So number 39's answer should be the code.

0.84

Answer:

The given inequality is

[tex]23m + 4 > 96[/tex]

Where [tex]m[/tex] represents minutes.

A problem that can be modeled by this inequality is:

Lucy earn $23 per minute, with an extra $4 due to punctuality, which must give more than $96 a day so she can make a living with that job. How many minutes does she need to work?

To solve the problem, we just solve the expression for [tex]m[/tex]

[tex]23m +4 > 96\\23m > 96-4\\23m > 92\\m > \frac{92}{23}\\ m > 4[/tex]

Therefore, Lucy needs to work more than 4 minutes in order to make a living with that job.

Answer:

125 students participated

Step-by-step explanation:

66% + 30% = 96%

100% - 96% = 4%

4% = 5 students

100% ÷ 4% = 25

25 × 5 = 125

125 students participated

Answer:

125 students

Step-by-step explanation:

30+66=96

100-96=4

5 students make up 4%.

100/4=25

25x5=125 students

Answer: 1. Not always accurate.

2. A football game.

3. By using the data from the winning percentage against number of games played.

Step-by-step explanation:

Meteorologists are responsible for making weather predictions, but their predictions are always not accurate because they use datas and theory to predict the scenarios of the weather or what it might be. Their predictions are not accurate because of changes in weather or data being used unexpectedly.

A scenario where I would use data to make a prediction could be in a football match or game where you i have a percentage of winning, which depends on how many times the game is played.

The winning percentage gives us the data on the probability of winning the game which would help predict how many times you'll win a game by how many times the game is played.

Answer:

64

Step-by-step explanation:

To get the answer, just perform the reverse operation of what the question said. In this case, you would want to multiply by the reciprocal, which is (8/3). So the answer is found by just solving 24*(8/3).

Answer:

The number is 64

Step-by-step explanation:

Let the number be x

3/8 of x = 24

x = 24 ÷ (3/8)

[tex]x=24*\frac{8}{3}\\\\x=8*8[/tex]

x = 64

Answer:

21, 22 and 26

Step-by-step explanation:

To answer this question first we need to know which are the factors of 12:

[tex]12= 2^2(3)[/tex]

So, now, we need 3 numbers that are between 20 and 30 and that only have one common factor with 12, in other words, they need to have just a 2 or a 3 in their factorization.

Let's take number 21:

[tex]21= (7)(3)[/tex], we can see that 21 only has a 3 and a prime so therefore it has only one common factor with 12

Now, let's take the number 22,

[tex]22=11 (2)[/tex], thus since 22 has a 2 and a prime, it has only one common factor with 12.

Now, let's take the number 26

[tex]26= 13 (2)[/tex], thus, since 26 has a 2 and a prime, it has only one common factor with 12.

Thus, the three possible answers are 21, 22 and 26

Answer: 37.64

Step-by-step explanation:

Given data:

Height of the cone = 4feet

Radius of the cone = 3feet

Therefore:

Perimeter of a cone = 1/3 * π * r*h

= 1/3 * 22/7 * 3² * 4

= 0.333 * 3.14 * 9 * 4

= 37.64 feet

The perimeter of the The cone and plane is 37.64feet

Answer:

A population that overshoots the carrying capacity can only do so for a limited amount of time because: since the ecosystem already has the maximum number it can take for a given specie, overshooting the ecosystem will not last long as:

1. Competitions for the limited available space and resources will result to increase death rate and emigration from the environment.

2. Birth rate would be controlled as the rate resources are used is greater than they are replenished. This limits productivity among species.

Step-by-step explanation:

The carrying capacity of an environment, in simple terms is the amount of a given specie that the environment can sustain without depleting or degrading the available resources. Population size of an environment increases if birth rate increases and death rate decreases, and if the environment also experience an increase in species coming to live there than they are leaving the environment. In other words, when resources are limited it affects the population size of an environment.

Step-by-step explanation:

6|x/3| < 18

Divide by 6

6/6|x/3| < 18/6

|x/3| < 3

Now we get two equations, one positive and one negative, remembering to flip the inequality

x/3 < 3   x/3 > -3

Multiply by 3 to isolate x

x/3 *3 < 3*3  and  x/3*3 > -3*3

x < 9          and      x > -9

Answer:

I'm gonna rewrite each sentence in a way that lines up a little more with the Algebraic expression you would end up with. Just keep in mind that either way of saying it is correct.

1. "8 times some number (a variable) minus 5"

8x-5

2. "13 plus some number"

13+x

3. "Some number over 7"

x/7 or x÷7

4. "d number of drinks times 3.50 plus 12 equals how much John spent (we'll call it J)"

12+3.50d = J

5. "Stacey bowled x number of games times the cost of one game (call it B) plus the cost of the shoes (call it P) which equals how much they spent (call it S)"

xB+P = S

6. "675.95 dollars was spent at the mall by a number of players (call it P) to equal the total cost per player)"

$675.95÷p (players) = 675.95/p (dollars/player)

Essentially you're making expressions or equations out of numbers you know and putting in variables as place holders for numbers you don't know. The variables can be whatever letters you like, but you'll want to write what each variable represents down nearby. Otherwise the reader/your teacher won't know what's what.

To find the slope of thine that passes through these points, use the slope formula. It can be read as “slope equals the second y-coordinate minus the first y-coordinate over the second x-coordinate minus the first x-coordinate.”

So we have [tex]\frac{-4 - 5}{-3 - 2}[/tex] and this simplifies to -9/-5 or 9/5.

Remember, a negative divided by a negative is a positive.
