The perimeter of rectangle ABCD is 72. The ratio of the lengths of the sides
is 1:2. What are the lengths of the sides?
a. 12 and 18
b. 12 and 24
c. 4.5 and 9
d. 6 and 12
Answer:
Step-by-step explanation:
The two lengths of the rectangle ABCD will be 12 and 24
What will be the length of the rectangle?It is given that
The perimeter of the rectangle
P=72 units
The ratio of the length
[tex]\dfrac{a}{b}=\dfrac{1}{2}[/tex]
Now from the formula of the perimeter of the rectangle
[tex]P= 2(a+b)[/tex]
[tex]\dfrac{a}{b}=\dfrac{1}{2}[/tex]
[tex]b=2a[/tex]
[tex]2(a+2a)=72[/tex]
[tex]6a=72[/tex]
[tex]a=12[/tex]
[tex]b=2\times 12=24[/tex]
Thus the two lengths of the rectangle ABCD will be 12 and 24

Oliver deposits $1,000 in his Interest-bearing bank account. The balance increases by %15 each month
Step-by-step explanation:
Oliver deposits P= $1,000
Then total amount A after n months given that the balance increases by %15 each month can be calculated as
[tex]A= 1000(1+15/100)^n[/tex]
Assuming the increase in amount is compounded monthly.
Point D is in the interior of ∠ABC. What is m∠DBC?
37.5 degrees
we know angled like this always have 180 degrees total between the 2. which means we can set up a little equation to solve for x. The equation is (3x+22)+(x-4)= 180. Initially we can take the solid numbers (22 and -4) and get rid of them by taking them to the 180. 180- 22 is 158. 158 + 4 is 162. now we have 3x + x = 162. we combine like terms. means we end up with 4x =162. We now divide by 4 which means we get 40.5. Now we know x is 40.5. Now dbc is just 40.5- 4 which is 37.5.
The measure of angle ∠DBC is,
⇒ ∠DBC = 35.5°
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Point D is in the interior of ∠ABC.
And, ∠ABD = (3x + 22)°
⇒ ∠DBC = (x - 4)°
Clearly, Both angle make a linear pair.
Hence, We get;
⇒ ∠ ABD + ∠DBC = 180°
⇒ (3x + 22) + (x - 4) = 180°
⇒ 3x + 22 + x - 4 = 180
⇒ 4x + 18 = 180
⇒ 4x = 180 - 18
⇒ 4x = 162
⇒ x = 162/4
⇒ x = 40.5
Hence, The measure of angle ∠DBC is,
⇒ ∠DBC = (x - 4)°
⇒ ∠DBC = (40.5 - 4)°
⇒ ∠DBC = 35.5°

What is the value of x
Answer:
x = 9
y = 5
Step-by-step explanation:
<N and < M are opposite equal sides. So they are equal as well. In addition, the base is equal to the other 2 sides. That means you are dealing with an equilateral triangle. All the angles are equal to 60 degrees.
7x - 3 = 60 degrees Add 3 to both sides
3 3
7x = 63 Divide by 7
x = 63/7
x = 9
Just for the sake of completeness, we'll find y
11y + 5 = 60 Subtract 5 from both sides
-5 -5
11y = 55 Divide by 11
y = 55 /11
y = 5

1)Mean < Standard Deviation
2)First Quartile < Standard Deviation
3)Median > Mean
4)Mean > Standard Deviation
The correct answer will be option (3) Median > Mean
ConceptFirst we will find the mean, median and standard deviation of given dataAfter finding mean, median and standard deviation we will compare them to find the correct answerHow to solve this problem?The steps are as follow:
The runs scored by youth baseball team over the course of a season is : 4, 8, 5, 12, 3, 9, 5, 2Mean is given as follow:[tex]x \: = \frac{4 + 8 + 5 + 12 + 3 + 9 + 5 + 2}{8} \\ x = 6[/tex]

Which ordered pair is NOT a solution to the inequality in the graph?
A. (0,0)
B.(-2,-4)
C.(0,2)
D.(-3,4)
Given:
The inequality is
[tex]y\leq 3x+2[/tex]
To find:
The ordered pair that is NOT a solution to the inequality in the graph.
Solution:
We have,
[tex]y\leq 3x+2[/tex]
Checking the inequality for (0,0), we get
[tex]0\leq 3(0)+2[/tex]
[tex]0\leq 2[/tex]
So, the equality is true for (0,0). it means (0,0) is a solution of given inequality.
Checking the inequality for (-2,-4), we get
[tex]-4\leq 3(-2)+2[/tex]
[tex]-4\leq -6+2[/tex]
[tex]-4\leq -4[/tex]
So, the equality is true for (-2,-4). It means (-2,4) is a solution of given inequality.
Checking the inequality for (0,2), we get
[tex]2\leq 3(0)+2[/tex]
[tex]2\leq 2[/tex]
So, the equality is true for (0,2). It means (0,2) is a solution of given inequality.
Checking the inequality for (-3,4), we get
[tex]4\leq 3(-3)+2[/tex]
[tex]4\leq -9+2[/tex]
[tex]4\leq -7[/tex]
This statement is not true. So, the equality is false for (-3,4). It means (-3,4) is not a solution of given inequality.
Therefore, the correct option is D.

A shipping container will be used to transport several 40-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 23000 kilograms. Other shipments weighing 7800 kilograms have already been loaded into the container.
The question is incomplete. The complete question is :
A shipping container will be used to transport several 40-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 23000 kilograms. Other shipments weighing 7800 kilograms have already been loaded into the container. Which inequality can be used to determine cc, the greatest number of 80-kilogram crates that can be loaded onto the shipping container?
Solution :
Given data :
Weight of the crate = 40 kg
Greatest weight that the container can load = 23000 kg
Weight of the other shipments on the container = 7800 kg
So the greatest number of 40 kg crates = c
Therefore, the weight of the other shipment + weight of crate x number of crates ≤ greatest weight of the container
7800 + (40 x c) ≤ 23000
7800 + 40c ≤ 23000
40c ≤ 23000 - 7800
40c ≤ 15200
c ≤ 380
Hence, the maximum number of 40 kg crate is 380.

The value of the variable 'x' in the arithmetic sequence 6, 9, 12, 15, x, .... will be 18.
What is an arithmetic sequence?A series of integers called an arithmetic succession or arithmetic chain of events has a fixed difference between the terms.
Let a₁ be the first term and d be a common difference.
Then the nth term of the arithmetic sequence is given as,
aₙ = a₁ + (n - 1)d
The sequence is given as,
6, 9, 12, 15, x, .....
The common difference between the succession term remains constant. Then the equation is given as,
15 - 12 = x - 15
Simplify the equation, then we have
15 - 12 = x - 15
3 = x - 15
x = 15 + 3
x = 18
