A rectangular dining room has an area of 20 square meters. It's perimeter is 18 meters. What are the dimensions of the dining room?
Answers
Answer:
The dimensions are:
Length = 5m and Width = 4m
Or
Length = 4m and Width = 5m
Step-by-step explanation:
A rectangular dining room has an area of 20 square meters. It's perimeter is 18 meters. What are the dimensions of the dining room?
Area of a rectangle = Length × Width
= LW = 20 m²
Perimeter of a rectangle =
2L + 2W = 18 m
Hence:
LW = 20...... Equation 1
L = 20/W
2L + 2W = 18 ...... Equation 2
We substitute
20/W for L in Equation 2
2(20/W) + 2W = 18
40/W + 2W = 18
Multiply through by W
40 + 2W² = 18W
2W² - 18W + 40 = 0
2W² - 10W - 8W + 40 = 0
(2W - 8 )(W - 5) = 0
2W - 8 = 0
2W = 8 , W = 8/2 = 4m
W - 5 = 0
W = 5m
W = 4m or 5 m
Solving for L
When W = 5 m
L = 20/W
L = 20/5
L = 4m
When W = 4m
L = 20/W
L = 20/4
L = 5m
Therefore, the dimensions are:
Length = 5m and Width = 4m
Or
Length = 4m and Width = 5m
Alicia purchased h half gallons of ice cream for 3.50 each p packages of ice cream cones for 2.50 each she purchased 14 items and spent 43$ which system of equations could be used to determine how many of each item Alicia purchased
Answers
Answer:
H + P = 14
3.50H + 2.50P = 43
Step-by-step explanation:
Given that
H denotes half gallons of ice cream
P denotes packages of ice cream cones
Now
H + P = 14
And,
3.50H + 2.50P = 43
So, the systems of equations would be
H + P = 14
3.50H + 2.50P = 43

Step-by-step explanation:
# carry on learning
The solution is, A. y = 5x, the equation represents the relationship between x and y.
What is equation?An equation can be stated as a mathematical statement that is made up of two expressions connected by an equal sign. In its normal form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
Direct proportion equation:
y = kx, where k is the coefficient of proportionality
We have:
x = 3 and y = 15
Using the equation to find the value of k:
15 = 3k
k = 15/3
k = 5
The equation of the line:
y = 5x
Correct choice is A
Hence, The solution is, A. y = 5x, the equation represents the relationship between x and y.

Angles 1 and 2 are supplementary.
• The measure of angle 1 is (2x - 3) ◦
• The measure of angle 2 is (-5x + 423) ◦
What is the measure of angle 2?
Answers
Answer:
1 = 157°
2 = 23°
Step-by-step explanation:
because the angles are supplementary, their angles will add up to 180°set up the equation (2x-3)+(-5x+423)=180combine like terms to get -3x+420=180subtract 420 from 180 to get -3x=-240divide by three and get x=80now plug in 80 for x in both equationsJim makes $5 an hour at the surf shop. His boss gives him a one-time bonus of $50. Sarah makes $8 an hour at the clothes store. Her boss givers her a one-time bonus of $14. If they both work 15 hours, who will have a bigger paycheck?
Answers
Answer:
Sarah had the bigger paycheck of $134
Step-by-step explanation:
First we would need to find the total amount of money each one of them made in those 15 hours. We do this by multiplying their hourly rate by the hours worked and then adding the bonus
Jim: (5*15) + 50 = x
75 + 50 = x
125 = x
Sarah: (8 * 15) + 14 = x
120 + 14 = x
134 = x
Finally, we can say that Sarah had the bigger paycheck of $134 which is $9 more than Jim's

a sphere has a volume of 905cm. what is the radius of the sphere rounded to the nearest whole number ?
Answers
Answer:
r = 6
Step-by-step explanation:
The value of radius of the sphere rounded to the nearest whole number is,
⇒ r = 6 cm
We have to given that,
Volume of a sphere = 905 cm
Since, We know that,
Volume of sphere = 4/3 (πr³)
Where, 'r' is radius of sphere.
Now, Substitute the given value, we get;
⇒ 905 = 4/3 (πr³)
⇒ 905 × 3 = 4 × 3.14 × r³
⇒ 2,715 = 12.56 × r³
⇒ r³ = 216.16
⇒ r = ∛216.16
⇒ r = 6 cm
Thus, The value of radius of the sphere rounded to the nearest whole number is,
⇒ r = 6 cm

Use the GCF and the distributive property to find the sum of 22+33
Answers
Answer:
22 + 33 = 55 the GCF of 22 and 33 is 11
Step-by-step explanation:
The sum of 22 and 33 by using distributive property will be; 55.
How to find Greatest common factor?The greatest common factor, as the name implies, is the greatest among all common factors among the quantities given.
We can factorize the quantities in the smallest relative factors possible (one level of factors over which all quantities can form themselves), and collect as many common factors as we could.
Factors:
22: 1 ,2, 11, 22
33: 1, 3, 11, 33
Both the numbers have a GCF of 11. Then by removing 11 from both numbers you end up with:
22 = 2 x 11
33 = 3 x 11
Now replace the values on the right of the equals sign into the original equation then;
(2 x 11) + ( 3 x 11)
The distributive property allows us to remove the common values and rewrite them;
11(2 + 3)
11(5)
55
The sum of 22 and 33 by using distributive property will be; 55.
