Answer: the perimeter of the rectangle is 30
Step-by-step explanation: so we know that the width of the rectangle is 5. Then it says that the length is two times more than the width....
5 times 2
Which is 10
Now all is left, you find the perimeter (all sides)
5+5+10+10
10+20
30
Therefore,
The perimeter of the rectangle is 30
Answer: 30
Step-by-step explanation: If the width is 5 and the length is twice the width then the length is going to be 10.
p=2(L+W)= 2(10+5)

A tin contains 20kg of ghee. Rao consumed 2⁄4 of it for preparing medicines. From the remaining ghee Rao used 2⁄5 and 1/2 of it for making laddu and burfi. How much ghee is left? *
Answer:
1kg ghee is left behind
Step-by-step explanation:
Here, we are to calculate the amount of ghee left.
Firstly, 2/4 was consumed for preparing medicine. This is same as 1/2
The amount used in preparing medicine is thus 1/2 * 20kg = 10kg
amount remaining = 20kg - 10kg = 10kg
She also use 2/5 and 1/2 of the remainder.
The total amount used is 2/5 + 1/2 = 9/10
The amount used is thus 9/10 * 10 = 9kg
what is left is thus 10kg -9kg = 1 kg
can any one put these from greatest to least plz help (more points) included

The students are doing a fundraiser to help out a friend. They are selling chocolate and cookies for $3 and $2.50 respectively. The cookies were presold to 60 people. At least how many of the chocolates must be sold to collect $255?
Answer:
At least 18 chocolates sold to collect $225
Step-by-step explanation:
~ Let's say x ⇒ the number of chocolates, y ⇒ the number of cookies ~
1. We can see that the number of chocolates/ cookies * the cost of chocolates/cookies = the total cost of chocolates/cookies. Provided this, it would be that 3x and 2.5y would represent the cost of chocolates and cookies.
2. It is given that there was $225 sold from chocolates and cookies, so we can say that 3x + 2.5y = 225 from this assumption.
3. That being said it is also known that the cookies were sold to 60 people, so we can assume that 60 cookies were sold out, 1 were person. With this information we can see that 3x ⇒ 3 * 60 = 180 ⇒ cost of cookies sold
4. Now we can substitute this value of 3x into the equation 3x + 2.5y = 225, as such: 3x + 2.5y = 225 ⇒ 180 + 2.5y = 225, and now we can solve for y ~
180 + 2.5y = 225,
2.5y = 225 - 180,
2.5y = 45,
y = 45/2.5,
y = At least 18 chocolates sold to collect $225

The triangle with a base of 4 and a height of 3 has an area of 6 square meters.
Based on the given information, we have a triangle with a base of 4 and a height of 3.
To calculate the area of the triangle, we use the formula:
Area = (base * height) / 2.
Substituting the values, we have
Area = (4 * 3) / 2

What is \text{P(not }3)P(not 3)start text, P, left parenthesis, n, o, t, space, end text, 3, right parenthesis? If necessary, round your answer to 222 decimal places.
Answer:
There is no enough information to determine probability of not having 3, P(not 3).
Suppose we were given the probability of having 3, P(3), we can easily find P(not 3).
The probability of success plus the probability of failure of an event is always equal to 1.
If p is the probation success, and q, of failure, then p + q = 1
So,
P(3) + P(not 3) = 1
That is
P(not 3) = 1 - P(3).

y = -9x - 14
x-intercept
y-intercept:
Answer: The x intercept is (-14/9,0) which means the x intercept is -14/9. The y intercept is -14.
Step-by-step explanation:
the x intercept is when y is 0 so using the equation we could solve for x by putting in 0 for y.
0=--9x - 14
+ 14 +14
14= -9x
x= -14/9
The y intercept is when x is zero so using the same method we will put in 0 for x in the equation and solve for y.
y= -9(0) - 14
y= 0-14
y= -14

A student wants to save at least $5000 for college. She begins with a savings account set up by her parents containing $2,500. Each month she deposits an additional $50 into the account. Fill in the first blank with the correct expressions that make the statement true.
(Attached is the statement and the choices)
Answer: She deposits 50 dollars per month right? But as known her parents deposited her 2,500. So, it will take her 50 months to complete the amount of 5000 dollars needed for college.
Step-by-step explanation: Im not good with equations but here we go.
First: AS we know the account already had 2,500, and every month she deposits 50$.
What we can do is to divide 2,500 divided by 50 which will be 50.
for a concert 1000 tickets are sold at either 1200shilling or 800 the total amount received is 928000 how many of each prize was sold
Answer:
320 tickets for 1200 shs and 680 tickets for 800 shs (multiply please)
Step-by-step explanation:
let; x - be the number of 1200 shs tickets.
y - number of 800 shs tickets.
x + y = 1000 tickets........................... eqtn 1
1200x + 800y = 928000 shs.........................eqtn 2
solve the simultaneous equation by elimination by multiplying eqtn 1 by 800 and eqtn 2 by 1 to be able to eliminate (y) when subtracting.
you will get ; -400x = -12800. Cancel out to get x as 320.
use any equation to get y
i used equation 1 ; 320 + y =1000.
subtract 320 from 1000 to get 680.
multiply the number of tickets by their corresponding amount to get the answer as;
1200 sh tickets = 384000 shs
800 sh tickets = 544000 shs.

Identify the center and radius of each. Photo attached.
Answer:
Center ~ ( -4, 3 ), Radius ~ 2; Option A
Step-by-step explanation:
~ We know that the standard circle equation ( x - a )^2 + ( y - b )^2 = r^2 provided r ⇒ radius of the circle, centered at ( a, b ) ~
1. If we are given the circle formula ( x + 4 )^2 + ( y - 3 )^2 = 4, it would be that the center points ( a, b ) would be the inverse of 4 and -3, provided the formula is -a and -b: center ( -4, 3 )
2. Now the radius in the formula ( x - a )^2 + ( y - b )^2 = r^2, is noted by r such that in ( x + 4 )^2 + ( y - 3 )^2 = 4, r^2 is 4 ⇒ r = √4 = 2
3. We now know that the center of this circle is ( -4, 3 ) with a radius of 2, and the only graph that represents that function is the first graph ~
Answer: Center ~ ( -4, 3 ), Radius ~ 2

Step-by-step explanation: In this problem, we're given that the height of a trapezoid is 10 and the bases has lengths of 9 and 24 and we're asked to find the area of the trapezoid. Since we're given the lengths of the bases, let's use our formula for the area of a trapezoid which involves the bases.
Area of a trapezoid is shown at the bottom your screen.
Now plug the information into the formula.
Simplify inside parentheses first.
Then multiply 1/2 by 10 to get 5.
Then you have (5)(13) which is 65.
So the area of the trapezoid is 65.

Answer:
Slope = 4
Step-by-step explanation:
Hi!
So, I can only see question a, so I will answer that.
This is asking for the slope given 2 points.
The line-slope formula states :
[tex]m = \frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}[/tex]
where m is the slope and the x and y values are the corresponding values from 2 coordinate points. The hard part of this is deciding which of your points is point 1 and which is point 2. It's arbitrary, so any selection is correct. We just have to stay consistent.
Let's let (3,12) be point 1 and (4,16) be point 2. Now we can write the corresponding x and y values into our formula:
[tex]m = \frac{({y_{2}-y_{1}})}{(x_{2}-x_{1})}\\m = \frac{(16-12)}{(4-3)}\\\\m = \frac{4}{1}\\\\m = 4[/tex]
So, the slope of the line through the 2 points (3, 12) and (3, 16) is 4
Svetlana has 1.2kg of apples and plenty of the other ingredients. She wants to make apple crumble for a maximum number of people. What is the maximum number of people she will be able to serve?
You must show your working
Answer: 12
Step-by-step explanation:
1200/750=1.6
1.6 X 8 = 12.8
12 number of maximum people she can serve.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Amount of Apples = 750 g
and, Svetlana has 1.2 Kg of apples
So, number of people she can serve
= 1200/750 x 8
= 1.6 x 8
= 12.8
= 12 people.
Hence, 12 number of maximum people she can serve.
