Answer:
Step-by-step explanation:
I'll assume that all the angles are 90°, and there is no bottom to the box.
To determine the wood needed, calculate the surface area of the bed. Since there is no bottom or top to the box, the amount of wood is 2(45 in × 21 in) + 2(22 in × 21 in) = 1890 in² + 924 in² = 2814 in²
To determine the soil needed, calculate the volume of the box.
volume = 45 in × 21 in × 22 in = 20,790 in³

What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
We have to given that;
You leaned the ladder against your house at a 30° angle of elevation.
And, The foot of the ladder is 7 feet from the foot of the house.
Now,
Let the length of ladder = x
Hence, We can formulate;
⇒ cos 30° = 7 / x
⇒ √3 / 2 = 7 / x
⇒ x = 14 / √3 feet
Thus, The length of ladder would be,
⇒ 14/√3 feet

A new treatment for depression involves a one month stay on a Caribbean island and daily therapy sessions with a team of 8 professionals. A researcher knows that people with untreated depression miss an average of μ = 4.30 days of work per month (σ = 1.1). It was found that a random sample of 121 depressed individuals who underwent the new treatment missed an average of M = 4.08 days of work per month following treatment. Thus, the research question is: what is the impact of this treatment on absenteeism (i.e., days missed from work)?

A scientist is investigating whether percent concentration can be used to predict density in apple juice. A scientist selected a random sample of 12 apple juice varieties and recorded the density, in pounds per cubic inch, and the percent concentration of each apple juice variety. The scientist wants to estimate the mean change in the density, in pounds per cubic inch, for each increase of 1 percent concentration of apple juice. Assuming the conditions for inference have been met, which of the following inference procedures is most appropriate for this investigation?
a. A linear regression t-interval for slope.
b. A matched-pairs t-interval for a mean difference.
c. A two-sample t-interval for a difference between means.
d. A one-sample t-test for means.
e. A two-sample z-interval for a difference between proportions
Answers
Answer:
The most appropriate inference procedure for the investigation is;
a. A linear regression t-interval for the slope
Step-by-step explanation:
Given that the slope of an horizontal line is zero, we have that there is no change in the y (dependent) variable when there is a change in the x-variable, therefore, it is important to find the true relationship between the two variables, 'x', and 'y'
The confidence interval of the slope is calculated and analyzed to determine if it excludes or includes, 0, such that, if the confidence interval exclude 0, then, it is unlikely that the slope is 0, therefore, there the relationship between the variables, 'x', and 'y' is significant
Therefore, a linear regression t-interval for the slope is most appropriate.

A house has increased in value by 35% since it was purchased. If the current value is $297,000, what was the value when it was purchased?
Answers
Answer:
Answer:
$260,000
Step-by-step explanation:
Explanation:
Given the problem above, we solve for original value
Hence, in this case, we are given
percentage (35%) and the New Value ($351,000).
We can substitute this into the formula and solve for X
Let X be the original price, Hence, X = 100%
Therefore, $351000 = 135%
Divide both sides by 135
351000÷ 135 = 135÷135
2600 = 1%
Multiply both sides by 100
2600 * 100 = 1% * 100
$260000 = 100% = X
Hence, final answer is $260000

A person is looking from a car to the top of a building. The angle of elevation to the top of the building from the car is 32°. The building is 200 feet away. How tall is the building? Round to the nearest foot.
Answers
Answer:
132.2 ft
Step-by-step explanation:
This is a right angle problem where 32 is the angle and 200 feet is the leg unederneath. To solve for the height we use tangent since we have the adjacent side and we are solving for the opposite side.
Steps:
1. tan32 = x/200

Which expression is equal to x + (f+g)? (1 point)
Answers
Answer:
x + f(x) + g(x)
Step-by-step explanation:
(f+g) = f(x) + g(x)
Therefore, x + (f+g) = x + f(x) + g(x)
If you are given equations to go with f(x) and g(x), you would plug in those equations to the above expression then combine like terms to find the fully simplified expression equal to x + (f+g).
James has collected 3985 stamps so far. He had 787 stamps from countries other than the United States. What percent of the stamps are from countries other than the United States?
Answers
Answer:
divide 787 by 3985 then multiply that by 100
Step-by-step explanation:
if it were 100 stamps total and 50 from non US countries, you could pretty easily tell it was half, or 50% to ge that you need to divide the number in question by the total so 50/100. which gets .5. to get the percent you multiply it by 100
so given the numbers we divide 787 by 3985 then multiply that by 100

Solve: (x −6)−(4.5−x )= −1.5
PLZ HELP
Answers
Answer:
x=9/2 Hope this helps!
Step-by-step explanation:
Let's solve your equation step-by-step.
x−6−(4.5−x)=−1.5
Step 1: Simplify both sides of the equation.
x−6−(4.5−x)=−1.5
x−6+−1(4.5−x)=−1.5(Distribute the Negative Sign)
x+−6+(−1)(4.5)+−1(−x)=−1.5
x+−6+−4.5+x=−1.5
(x+x)+(−6+−4.5)=−1.5(Combine Like Terms)
2x+−10.5=−1.5
2x−10.5=−1.5
Step 2: Add 10.5 to both sides.
2x−10.5+10.5=−1.5+10.5
2x=9
Step 3: Divide both sides by 2.
2x/2=9/2
x=9/2
Answer is 9/2.

Shaun is 1.88 m tall.
David is 6 cm taller than Shaun.
How tall is David
Answers
David is 1.94 meters tall.
Given that,
Shaun is 1.88 meters tall.
David is stated to be 6 centimeters taller than Shaun.
To determine David's height, we need to add the additional height to Shaun's height.
Since there are 100 centimeters in a meter, we can convert the 6 centimeters to meters by dividing it by 100: 6 cm / 100 = 0.06 meters.
Now, we can add this height to Shaun's height to find David's height:
1.88 meters + 0.06 meters = 1.94 meters.
Therefore, David is 1.94 meters tall.
