i need help asap plz
Answer:
A
Step-by-step explanation:
The constant of proportionality is the ratio between the two proportional variables in a directly proportional relationship. In this case, the variables are [tex]x[/tex] and [tex]y[/tex].
To find the constant of proportionality, all we have to do is divide any value of [tex]y[/tex] by its corresponding value of [tex]x[/tex]. Let's take the values in the first row of the table. We know that [tex]x=2[/tex] and [tex]y=12[/tex], so the constant of proportionality is [tex]\frac{y}{x}=\frac{12}{2} =6[/tex]. Hope this helps!
if a sweatshirt is $20 and the discount is 30% how much is the sweatshirt
Answer:
$14.00
Step-by-step explanation:
First take $20 and divide by 100. Then you multiply by 30 to get the reference which was $6. If the sweatshirt was $20 and the reference was $6, you would subtract $20 - $6 and get $14.
Answer: $14.00
Step-by-step explanation: First take $20 and divide by 100. Then you multiply by 30 to get the reference which was $6. If the sweatshirt was $20 and the reference was $6, you would subtract $20 - $6 and get $14.

What is the quotient?
The quotient is the number which is generated when we perform division operations on two numbers. Basically, it is the result of the division method.
There are four main terminologies used in the arithmetic division such as divisor, dividend, quotient and remainder.

n/9 + 2/3 = -2/3
Answer:
n = - 12
Step-by-step explanation:
n/9 + 2/3 = - 2/3
n/9 = - 2/3 - 2/3
n/9 = - 4/3
n = 9(- 4/3)
n = -36/3
n = - 12

Answer:
B and D are correct.
Step-by-step explanation:
To find the area of a rectangle, simply multiply its length by its width. In this case, the length of the rectangle is [tex]5[/tex] m and the width of the rectangle is [tex]3[/tex] m, so its area must be [tex]5*3=15[/tex] square meters.
To find the area of a triangle, divide the product of the triangle's base and height by [tex]2[/tex]. As an algebraic expression, that would be [tex]\frac{bh}{2}[/tex], where [tex]b[/tex] and [tex]h[/tex] are the triangle's base and height, respectively. In this case, [tex]b=6[/tex] and [tex]h=5[/tex], so the triangle's area is [tex]\frac{6*5}{2}=15[/tex] square meters.
Now, let's look at the statements.
A: The triangle's area is [tex]15[/tex] square meters, not [tex]30[/tex], so A is incorrect.
B: The rectangle's area is [tex]15[/tex] square meters and the triangle's area is also [tex]15[/tex] square meters. Because the two figures have the same areas, their areas are equal, so B is correct.
C: We've already established that the two figures have equal areas, so one can't have a greater area than the other. Therefore, C is incorrect.
D: The rectangle's area is indeed [tex]15[/tex] square meters, so D is correct.
Hope this helps!
Answer:
B is correct, and D is correct
if you multiply 3 times 5 you get 15 m which is the area for the rectangle, then you have to find the area for the triangle, which you would have to multiply 6 times 5 which you get 30, then divide 30 by 2, which would be 15!

Answer:

Step-by-step explanation:
Given
2t - [tex]\sqrt{2}[/tex] = 3t + [tex]\sqrt{2}[/tex] ( add [tex]\sqrt{2}[/tex] to both sides )
2t = 3t + 2[tex]\sqrt{2}[/tex] ( subtract 3t from both sides )
- t = 2[tex]\sqrt{2}[/tex] ( multiply both sides by - 1 )
t = - 2[tex]\sqrt{2}[/tex]

Equate each factor to zero and solve for x
- x + 2[tex]\sqrt{3}[/tex] = 0 ( subtract 2[tex]\sqrt{3}[/tex] from both sides )
- x = - 2[tex]\sqrt{3}[/tex] ( multiply both sides by - 1 )
x = 2[tex]\sqrt{3}[/tex]
- 3x - [tex]\sqrt{2}[/tex] = 0 ( add [tex]\sqrt{2}[/tex] to both sides )
- 3x = [tex]\sqrt{2}[/tex] ( divide both sides by - 3 )
x = - [tex]\frac{\sqrt{2} }{3}[/tex]

8 men can cut 3 kg of onions in 1 hour 40 minutes then how many people are required to cut the same amount of onions in 40 min
Answer:
3 men approx
Step-by-step explanation:
Given data
8 men can cut 3 kg of onions in 1 hour 40 minutes
let us convert the time to minutes
=1 hour 40min
=60+40
=100 minutes
We are told that
8 men will cut the 3kg onion in 100minutes
Hence x men will cut 3 kg onion in 40 minutes
cross multiply
100x= 40*8
100x=320
divide both sides by 100
x= 320/100
x=3.2men
Hence it will take 3 men approx to cut the onions

Bill needs to find the area of the ground covered by a conical tent. The tent is 12 feet tall and makes a 70° angle with the ground. Which expression can be used to find the area?
Answer:
Step-by-step explanation:
To get the area of the cone we need to find the radius first.
tan 70=r/12
r=12tan 70
area of a circle is given by:
A=πr²
thus the area of the ground covered by the tent will be:
A=π(12tan70)²
The answer is
A] A=π(12tan70°)²

Parallelogram FGHJ was dilated and translated to form similar parallelogram F'G'H'J'. What is the scale factor of the dilation?
Answer:
The scale factor is 4
Step-by-step explanation:
Given
See attachment for parallelograms
Required
Determine the scale factor (k)
Using sides FG and F'G' as a point of reference:
[tex]FG = 2\ units[/tex]
[tex]F'G' = 8\ units[/tex]
The scale factor (k) is calculated as:
[tex]k = \frac{New}{Original}[/tex]
[tex]k = \frac{F'G'}{FG}[/tex]
[tex]k = \frac{8\ units}{2\ units}[/tex]
[tex]k = 4[/tex]
The age of trees in a forest is known to be approximately normal with an average age of 40 years and a standard deviation of 10 years. About ____ of the trees have ages between 10 years and 70 years.
Answer:
Not 95%
Step-by-step explanation:
The normal distribution is also known as the Gaussian distribution. About 99.7% of the trees have ages between 10 years and 70 years.
What is Normal Distribution?The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.
Given that the age of the tree is normally distributed. Also, the following details are known,
Standard Deviation, σ = 10 years
Mean, μ = 40
Now, the z-score and the p-values for the value of 70 and 10 can be written as,
Z = (X-μ)/σ
Z = (70 - 40)/10
Z = 3
The p-value for z-score of 3 is 0.9987.
Z = (X-μ)/σ
Z = (10 - 40)/10
Z = -3
The p-value for z-score of -3 is 0.0013.
Further, the percentage of the trees have ages between 10 years and 70 years is,
Percentage = 0.9987 - 0.0013
= 0.9974
= 99.7%
Hence, About 99.7% of the trees have ages between 10 years and 70 years.
