Answer:
To convert fraction to decimal, divide 3/10, which would give you . 3 which is already a decimal. To convert decimal to percent, multiply by 100 which would give you 30, hence 30%
Answer:
3 out of 10 is 30%
Step-by-step explanation:
3/10 x 100% = 30%

4X + 24 - X + 5 ≤ 62
Answer:
Combine like terms:
3x + 29 ≤ 62
-29 -29
3x = 33
Divide by 3 on both sides.
x = 11!
Answer:
x is 11
Step-by-step explanation:
4X + 24 - X + 5 ≤ 62
24 + 5
is 29
29-3x ≤ 62
-3x ≤ 33
-x ≤ 11
x ≥ 11

Answer:
[tex]2 - i[/tex]
Step-by-step explanation:
Substitute i for x. Remeber i means imaginart number.
[tex] {i}^{3} - 2 {i}^{2} [/tex]
Use the Imaginary number exponents rules
[tex] {i}^{2} = - 1[/tex]
[tex] {i}^{3} = - i[/tex]
[tex]i {}^{4} = 1[/tex]
Simplify the equation.
[tex] - i - ( - 2)[/tex]

A developer is building a scale model of the city. From the roof of an apartment complex, the developer points two lasers at the taller office building across the street. The first laser points to the base of the building and the second laser points to the top of the building. The first laser beam has an angle of depression of 36° and is 155.7 feet long. The second has an angle of elevation of 32° and is 148.6 feet long. How tall is the office building? How far apart are the apartment complex and the office building? Round your answers to the nearest foot.
Answer:
a. 170 ft b. 126 ft
Step-by-step explanation:
a. How tall is the office building?
The two laser lights with the length of the taller office building, L form a triangle with sides 155.7 feet, 148.6 feet and L with angle 36° + 32° = 68° facing the taller office building.
We use the cosine rule to find the length of taller office building.
So, L² = 155.7² + 148.6² - 2(155.7)(148.6)cos68°
L² = 24242.49 + 22081.96 - 46,274.04(0.3746)
L² = 46324.45 - 17334.56
L² = 28989.89
L = √28989.89
L = 170.26 ft
L ≅ 170 ft
b. How far apart are the apartment complex and the office building?
Using one of the lights, the distance between the buildings, d, the laser light(being the hypotenuse side) and the building (being the opposite side)form a right angled triangle.
So, using the 155.7 feet light at 36 angle,
cos36 = d/155.7
d = 155.7cos36
d = 155.7(0.8090)
d = 125.96 ft
d ≅ 126 ft

A pharmaceutical company is testing a new drug. For the study, the company enrolled 200 people who had previously been diagnosed with a specific condition. Half took the study drug and half took a placebo. Throughout the study, the participants were routinely asked to fill out a 50-question survey. After six months, the participants on the study drug showed positive improvements in their answers. What is the best way the company could improve this study to prove more thoroughly that its medications work
Answer:
The quantitative data must be collected and test statistics performed.
Step-by-step explanation:
The quantitative data must be collected by performong different test such blood test etc. Then the improvement in the medications work can be found out by applying different test statistics such as difference tests , etc.
The quantititave data will show how much there has been improvement by using drugs and placebo.
The test statistic will provide a basis for the quick decision without waiting for 6 months.

A rectangle has a width of 6 and a length of 2x+8. The area is 108 squared, what is the value of x?
Answer:
x = 5
Step-by-step explanation:
108 = 6(2x + 8)
108/6 = 18
18 = 2x + 8
18 - 8 = 10
10 = 2x
10/2 = 5
5 = x

Laura is bowling 5 games. Her first 4 scores were 103, 143, 101, and 110.
To end up with an average score of at least 126.8, what is the lowest score Laura will need in the fifth
game?
Answer:
The least 5th score is 177
Step-by-step explanation:
Given
[tex]First\ 4: 103, 143, 101, 110.[/tex]
[tex]Average = 126.8[/tex]
Required
The least 5th score
Represent the 5th score with x.
The average is calculated as:
[tex]Average = \frac{\sum x}{n}[/tex]
So, we have:
[tex]126.8 = \frac{103 + 143 + 101 + 110 + x}{5}[/tex]
[tex]126.8 = \frac{457 + x}{5}[/tex]
Multiply both sides by 5
[tex]634= 457 + x[/tex]
Solve for x
[tex]x = 634- 457[/tex]
[tex]x = 177[/tex]

Answer:
44m²
Step-by-step explanation:
GIVEN :-
Lengths of all the sides of the figure.TO FIND :-
Area of the figureSOLUTION :-
Divide the whole figure into 2 rectangles.
Dimension of 1st rectangle = 6m × 2mDimension of 2nd rectangle = 8m × 4mArea of 1st rectangle = 6 × 2 = 12m²
Area of 2nd rectangle = 8 × 4 = 32m²
∴ Area of the whole figure = 32 + 12 = 44m²

Solve for x. Enter the solutions from least to greatest. 5x^2 - 20x + 15 = 0
Answer:
x = {1, 3}Step-by-step explanation:
5x² - 20x + 15 = 0x² - 4x + 3 = 0x² - 4x + 4 = 1(x - 2)² = 1√(x - 2)² = √1x - 2 = ± 1x = 2 ± 1x = 1, x = 3x^2-3=0 solve for all real values of x
Step-by-step explanation:
x²-3=0
x²=3
x=√3
stay safe healthy and happy.Answer:
x = √3
x = - √3
Step-by-step explanation:
x^2 - 3 = 0 Add 3 to both sides
x^2 = 3 Take the square root of both sides.
sqrt(x^2) = sqrt(3)
x = +/- sqrt(3)
Remember that the - root is also a solution to the question. Also for this question don't put the - sign under the root sign. That is an entirely different question.
Maria has a bag with 6 red marbles, 6 blue marbles, and 4 green marbles looking Maria picks one . She does not replace it and she picks another oneOn the first pick, Maria gets a green marble. What is the probability that she gets a red marble on her second pick?
Answer: Hello there!
initially Maria has 6 red marbles, 6 blue marbles, and 4 green marbles.
You know that in the first pick, Maria gets a green marble ( this means that now there are 3 green marbles left)
Now we want to know the probability that she gets a red marble on the second pick.
Now there are 6 + 6 + 3 = 15 marbles in the bag, and 6 of them are red ones. Then the probability of getting one red is the number of red ones divided by the total amount ( which is the ratio of red marbles to total marbles)
this is 6/15.
now you can see that there is no 6/15 in the options, so we need to see which one is equivalent.
if we took the option C, 2/5, and multiply both denominator and numerator by 3, we get (3*2)/(3*5) = 6/15, then 2/5 and 6/15 are equivalents.
Then the correct answer is C.
