The sides of a rectangle are in the ratio 5 : 4. If the perimeter of the rectangle is 360 cm , find its area
Answer:
Step-by-step explanation:
let, the length is z
thus the ratio will be 5z : 4z
perimeter = 2 (a + b)
360 = 2 ( 5z + 4z )
180 = 9z
z = 20 cm
length = 100 cm and width = 80cm
area = length * width
area = 100*80
area = 8000cm²

Which shows the list of numbers in order from least to greatest?
Answer: -2, |-4/5|, |-1|, |3.5|, |-4.2| (option A)
Step-by-step explanation:
Absolute value bars make all numbers the positive version of themselves, so you can make |-4.2| into 4.2, |-4/5| into 4/5, and so on.
Once you do that, you just order 4.2, 4/5 (which is also 0.8), 1, -2, and 3.5 in order to get:
-2, 4/5, 1, 3.5, 4.2
Finally, you choose the option that contains those numbers in order with the absolute value bars added. That is how you get A as the answer.

There are two extra credit questions on the Biology test, and 27 questions overall [including the afore-mentioned two]. If Jo answers all questions [including the extra credits] correctly, and each is worth the same amount, what score does she earn?
Answer: 108%
27 − 2 = 25. 100 / 25 = 4. So, each question is worth 4%. 2 x 4% = 8% That’s how much the extra credit is worth. 100% (main test) + 8% (extra credit) = 108% (best score possible).

Answer:
2, 2, undefined, -6
Step-by-step explanation:
There is a solid dot at g(-5) = 2.
There is an open circle at g(-4), but to the left of that, we have ...
g(-4.0001) = 2
As we said, there is an open circle at g(-4), so ...
g(-4) = undefined
To the right of -4, g(x) is defined again:
g(-3.999) = -6
Write the equation −x+3y=6 in slope-intercept form. Then graph the line described by the equation.
Please help fast ?
Answer:
y=x/3+2
Step-by-step explanation:
Slope-intercept form is y=mx+b where m is the slope and b is the y-intercept.
3y=x+6
We need y so we divide both sides by 3 and we get
y=x/3+2
Answer:
y=1/3 + 2
Step-by-step explanation:
-x+3y=6
add x to both sides (if you add the same amount to both sides, the equation is still equal)
3y=-x+6
divide the whole thing by 3
y=1/3 + 2
so basically your slope is 1/3. That means you rise one, over three.
Plot a point at 2 on the y axis, which is the vertical line on the graph.
Go up one box, and then go right 3 and plot another point.
Keep doing the rise 1 over 3 until you have enough points for a line. 2 points should do, but more points on a graph = a better line.
By the way, slope-intercept form is y=mx+b.
m = slope (steepness of line, 1/3) b = y-axis intercept (the place that the line touches the y axis)
If you're still stuck with linear equations, take your equation and put it into Desmos graphing calculator, which can be found with a simple search.

Find the value of x when 6 - 3x = 5x - 10x + 18.
The value of x is
x
Answer:
x = 6
Step-by-step explanation:
First, simplify both sides:
6 - 3x = -5x + 18
Move like terms to one side. Note that when you move a term from one side to another, the sign is changed (+ --> -)
6 - 18 = -5x + 3x
-12 = -2x
x = 6

B. 78% of the women who said yes
C. 80% of the people who said yes
D. 252 men who said yes, If a large group of 300 men
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
A survey was done of men's and women's hands to see if the ring finger appeared longer than the index finger or not.
(A) There are the total number of men is 34 (28+6)
The percentage of the men who said yes = (28/34)×100
The percentage of the men who said yes = 82.3529 %
82.3529% rounded to the nearest one is 82
The percentage of the men who said yes = 82 %
(B) There are the total number of women is 45 (35+10)
The percentage of the women who said yes = (35/45)×100
The percentage of the women who said yes = 77.7778 %
77.7778%. rounded to the nearest one is 78
The percentage of the women who said yes = 78 %
(C) There are the total number of people is 79 (28+6+35+10)
The percentage of the people who said yes = (63/79)×100
The percentage of the people who said yes = 79.746 %
The percentage of the people who said yes = 80 %
(D) 82 % of men who said yes in this sample
If a large group of 300 men had the same rate of response as men in this sample
So 82 % of 300 men = 82 % of 300 = (82/100)300 = 246

Mrs.Thomas bought a blanket shaped like an equilateral triangle that measures 3 feet on each side . She wants to put a ribbon around the edge . How long should the ribbon be ?
Answer: 9 feet long
3 sides that are 3 feet each, simply multiply 3 by 3
The length of ribbon should be 9 feet.
What is equilateral triangle?An equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°. It is also a regular polygon, so it is also referred to as a regular triangle.
Given
shape of blanket is equilateral triangle,
and length of each side = 3 feet
to put a ribbon around the edge, we need to calculate the perimeter of triangle,
perimeter of equilateral triangle = 3a
where a is side of triangle,
P = 3a = 3 x 3
p = 9 feet
Hence the length of ribbon should be 9 feet.

if a boat travels 408 miles in 6 hours how many miles can it travel in 1 hour
Answer:
Simple answer is 68
Step-by-step explanation:
In the equation, you can already tell that there is 408 miles traveled in 6 hours. Now since you are trying to only get the answer for how far it would go in one hour, you would have to divide 408 into 6 equal numbers, which would be 68. To prove it is correct, multiply 68 6 times and you will be back to 408.
Answer:

made? Express your ratio as a fraction or with a colon.
The ratio of non-winners in group A to non-winners in group B is; 85:212
Ratios and ProportionsGroup A contains 255 people;
Since two-thirds of the people in group A are winners;
2/3 × 255 = 170Hence, the number of non-winners in group A is; 255 -170 = 85.
Also, since there are 170 winners in Group B also, the number of non-winners in group B is;

What two requirements do you need to perform a dilation?
Answer:
Explanation:
There are several ways that dilation is used in real life. Here are several:
In graphic design. I actually do some graphic design, and I use dilation a lot. It is common to dilate photos to fit the space that you want it to fit.
In police work and crime investigation. Detectives and police dilate photos to see smaller details and evidence.
In architecture. It is normal for architects to make a prototype of their design or building. In order to make the building true to the prototype, they must dilate the scale and measurements.
In the doctor's office. Dilation is used in eye exams so that the eye doctor can view the patient's eye better. After a while it will slowly reduce in size and return back to normal.
