Answer:
6; 22; 20 (ft.)
Step-by-step explanation:
1) if the length of the each side are: n; 4n-2 and 4n-4, then the expression of the perimeter can be written: P=n+4n-2+4n-4 or P=9n-6.
2) if according to the condition perimeter is 48 (ft.), then
9n-6=P; ⇔ 9n-6=48; n=6.
3) if n=6, then the required lengths of the sides are:
n=6 (ft.);
4n-2=22 (ft.);
4n-4=20 (ft.)
work out the percentage change when a price of £70 is decreased to £49
Answer:
30% decrease in price
Step-by-step explanation:
Since 70-49=21, we know that the price decreased by 30 pounds. The formula to find a percentage decrease is that you should then divide the original number(70) by 21(that equals 0.3!) 0.3 as a percentage would then be 30%, so the answer is there is a 30% decrease in price.
Question is based on Fraction
A man intended to distribute a certain amount of money he had, by giving 2/5 to his wife and the remaining amount equally to his three sons. However, he had to give 1/6 of this amount to his brother before he distributed it as intended. He distributed the remaining amount as originally intended.
Q1. The amount a son received was 40000 rupees less than the amount he was to receive originally. Find the amount the man had intially ?
9514 1404 393
Answer:
12,00,000 rupees
Step-by-step explanation:
The fraction originally intended for each son was ...
(1/3)(1 -2/5) = 1/3(3/5) = 1/5
The fraction each son actually received was ...
(1 -1/6)(1/5) = (5/6)(1/5) = 1/6
The difference in these amounts as a fraction of the original distribution is ...
1/5 - 1/6 = (6/30) -(5/30) = 1/30
Then the original distribution is 30 times this difference:
30×40000 rupees = 12,00,000 rupees
_____
Additional comment
Originally-intended distribution (rupees):
wife: 4,80,000each son: 2,40,000Actual distribution:
brother: 2,00,000wife: 4,00,000each son: 2,00,0001,00,000 = 1 lakh

Which of the following number sentences is an example of the Distributive Property?
7 × (10 + 9) = (7 × 10) + (10 × 9)
7 × (10 + 9) = (7 + 10) x 9
7 × (10 + 9) = (7 × 10) + 9
7 × (10 + 9) = (7 × 10) + (7 × 9)
Answer:
d. 7 × (10 + 9) = (7 × 10) + (7 × 9)
Step-by-step explanation:
The format of writing numbers in distributive property is a(b+c) = (a×b)+(a×c)
We can see that in choice d. 7 × (10 + 9) = (7 × 10) + (7 × 9) it is in correct format of writing numbers in distributive property. Thus, choice d. is correct.
Verification:-
a(b+c) = (a×b)+(a×c)
7 × (10 + 9) = (7 × 10) + (7 × 9)

Answer:
7
Step-by-step explanation:
To solve this, we have to solve for h.
We can use order of operations to figure this one out.
[tex]18h-9h-7h+3=17\\18h-9h-7h=14[/tex]
Now that every variable on the left side of the equation has an h, we can factor.
[tex]h(18-9-7)=14\\h=\frac{14}{18-9-7} \\h=\frac{14}{2} \\h=7[/tex]

The driving distance from Los Angeles to a Chicago is 2,054 mi. The distance from Chicago to Boston is 983 mi. About how many miles is the drive from Los Angeles to Boston though Chicago?
Step-by-step explanation:
given :
The driving distance from Los Angeles to a Chicago is 2,054 mi. The distance from Chicago to Boston is 983 mi.
so, the numbers of mile driving from Los Angeles to Boston though Chicago =
2,054 + 983 = 3.037 mi
Which conic's equation has 2 squares with the same signs and different leading coefficients?
We want to see which is the conic equation that has 2 squares with the same sign and different leading coefficients.
We will see that it is the equation of the ellipse.
Now let's see why that is the correct answer.
The general conic equation is of the form:
[tex]A*(x - a)^2 + B*(x - b)^2 = R^2[/tex]
Where A and B are the leading coefficients, (a, b) is the center of the figure, and R is the average radius of the figure.
For example, if A = B, this would be the equation of a circle, but we must have two different leading coefficients.
If we write:
A = 1/C
B = 1/K
(both are positive, because "it has two squares with the same signs").
Then we get the equation:
[tex]\frac{ (x - a)^2}{C} + \frac{(x - b)^2}{K} = R^2[/tex]
We get the equation we wanted.
The same sign in both square parts and different leading coefficients.
The above equation is the general equation of an ellipse.

Ben is a waiter at a restaurant. on Saturday, Ben got up at 6:30am, started work at X.am and finished work at X.pm. how long in hours did Ben work that Saturday
Answer:
12 hours
Step-by-step explanation:
X = 6:30
From 6:30 am to 6:30 pm = 12 hr
The number of hours that Ben worked at the restaurant can be calculated by the expression, Xpm - Xam.
The number of hours that Ben worked can be represented as:
= Time he finished working - Time he started working
= X pm - X am
If for instance, he started work at 7 am and finished at 12 pm, he would have worked:
= 12 - 7
= 5 hours
The expression that shows the length of time he worked can therefore be concluded to Xpm - Xam.

Twice the larger of two consecutive integers is equal to fifteen less than three times the smaller. Find the
two integers.
Answer:
Step-by-step explanation:
2*x = 3(x - 1)-15 Remove the brackets
The larger of two consecutive integers is x
The smaller of two consecutive integers is x - 1
2x = 3x - 3 - 15 Combine the right
2x = 3x - 18 Subtract 3x from both sides
2x - 3x = 3x-3x - 18 Combine
-x = - 18 Multiply by - 1
x = 18
x - 1 = 17
What is the area of this shape?
Answer:
235 cm^2
Step-by-step explanation:
First you should divide this shape into to rectangles or squares. Then you can easily find the area.
20-11=9
We have a rectangle and a square.
(11*14) + (9*9)
Answer:
A = 235 cm²
Step-by-step explanation:
The figure is composed of 2 rectangles.
main rectangle has dimensions length = 20 cm , breadth = 9 cm
The attached rectangle , on top has dimensions
length = 11 cm , breadth = 14 - 9 = 5 cm
Total area (A) is the sum of the areas of the 2 rectangles
A = (20 × 9) + (11 × 5) = 180 + 55 = 235 cm²
