Answer:
20
Step-by-step explanation:
20 is the least common denominator
2/5, 1/2, and 3/4 fractions have a Least Common Denominator of 20.
What is Least Common Denominator?The lowest common denominator is defined as the set of fraction denominators with the lowest common multiple. The lowest positive integer with more than one denominator in the set is LCD.
What is the fraction?A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
We have to determine the Least Common Denominator of fractions 2/5, 1/2, and 3/4
We need to calculate the factors of the denominators 5, 2, and 4.
⇒ 5 = 5 × 1
⇒ 2 = 2 × 1
⇒ 4 = 2 ×2 × 1
The LCD would be:
⇒ 5 × 2 ×2 × 1 = 20
Hence, 2/5, 1/2, and 3/4 fractions have a Least Common Denominator of 20.

Step-by-step explanation:
Since QS is an angle bisector then PQs and SQR are similar. Using the similarity theorem;
PQ/PS = QR/SR
45/20 = x/18
Cross multiply
20x = 45 * 18
20x = 810
x = 810/20
x = 40.5
Hence the value of x is 40.5
Which expression is equal to x + (f+g)? (1 point)
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?
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

Shaun is 1.88 m tall.
David is 6 cm taller than Shaun.
How tall is David
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.

Solve: (x −6)−(4.5−x )= −1.5
PLZ HELP
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.

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
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 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.
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
2. (tan32)200=x
3. x=132.2 ft

Samir and Christian had a total of 360 marbles Samir lost 28 marbles while Christian brought 18 more marbles both of them had an equal number of marbles in the end how many marbles did Samir have at the beginning
Step-by-step explanation:
Marbles altogether = 360
Marbles Samir Lost = 28
360 - 28 = 332
Marbles Christian bought 18
332 + 18 = 350
Marbles both had in the end = 350 ÷ 2 = 175
Marbles Samir have at the beginning = 175 + 28 = 203

Tegan had 13 cups of strawberries. She wants to divide the strawberries into small daily servings. How many 13cup servings are in the 13 cups of strawberries?
Answer:
I would assume you meant that each cup serving = 1 cup.
So the answer would be 13 cup servings.
If it is a different number, such as cup serving = 1/2 cup, then 26 cup servings would be the answer.
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?
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

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
