The lenght of one side rectangle is x cm the length of longer side is (X+4) cm if the rectangle has the peimeter of 48 cm find the area?
Answer: 140cm²
Step-by-step explanation:
Perimeter of a rectangle is calculated as: = 2(length + width)
where,
Length = x+4
Width = x
Therefore, perimeter = 2(length + width)
2(x + x+4) = 48
2(2x + 4) = 48
4x + 8 = 48
4x = 48 - 8.
4x = 40
x = 40/4
x = 10cm
The other side = x+4 = 10+4 = 14cm
Area = length × width
Area = 10cm × 14cm
Area = 140cm²
Events A and B are mutually exclusive. Suppose event A occurs with probability 0.36 and event B occurs with probability 0.31. Compute the following. (If necessary, consult a list of formulas.) (a) Compute the probability that A does not occur or B does not occur (or both). 0. x 5 ? (b) Compute the probability that either A occurs without B occurring or A and B both occur. 0.36
Answer:
Events A and B are dependent
Step-by-step explanation:
If A and B are two events such as A and B are dependent then
P(A∩B) P(A) P(B)
An event A will occur with probability 0.4 that is
An event B will occur with probability 0.6 that is
The probability that both A and B will occur is 0.20 that is P(A∩B) = 0.20
Therefore,
P(A∩B) P(A) P(B)
So,
events A and B are dependent

Segment FG begins at point F(-2, 4) and ends at point G(-2, -3). The segment is translated 3 units left and 2 units up, then reflected across the y-axis to form segment F'G'.How many units long is segment F'G'?
Answer:
[tex]F'G' = 7[/tex]
Step-by-step explanation:
Given
[tex]F = (-2,4)[/tex]
[tex]G = (-2,-3)[/tex]
Required
Distance of F'G'
The transformation that give rise to F'G' from FG are:
TranslationReflectionThe above transformations are referred to as rigid transformation, and as such the side lengths remain unchanged.
i.e.
[tex]F'G' = FG[/tex]
Calculating FG, we have:
[tex]FG = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
Where:
[tex]F = (-2,4)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]G = (-2,-3)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]FG = \sqrt{(-2 - -2)^2 + (4 - -3)^2}[/tex]
[tex]FG = \sqrt{(0)^2 + (7)^2}[/tex]
[tex]FG = \sqrt{0 + 49}[/tex]
[tex]FG = \sqrt{49}[/tex]
Take positive square root
[tex]FG = 7[/tex]
Recall that:
[tex]F'G' = FG[/tex]
[tex]F'G' = 7[/tex]
1-point free throw 2-point field goal he made 35 shots he scored 62 points how many of each shot does he make in 1 minute write the two equations for the problem
Answer:
x + y = 35 equation 1
x + 2y = 62 equation 2
He made 8 1 point free throw
He made 27 2 point field goal
Step-by-step explanation:
let x = 1 point free throw
y = 2 point field goal
two equations can be derived from the question
x + y = 35 equation 1
x + 2y = 62 equation 2
Subtract equation 1 from 2
y = 27
Substitute for x in equation 1
x = 35 - 27 = 8
He made 8 1 point free throw
He made 27 2 point field goal

Stella needed to get her computer fixed. She took it to the repair store. The technician
at the store worked on the computer for 3.25 hours and charged her $75 for parts.
The total was $188.75. What was the cost of labor, per hour?
9514 1404 393
Answer:
$35 per hour
Step-by-step explanation:
The total charge is the sum of costs of parts and labor. If h is the cost of a labor hour, then we have ...
188.75 = 75 + 3.25h
113.75 = 3.25h . . . . . . . . subtract 75
113.75/3.25 = h = 35 . . . divide by the coefficient of h
The cost of labor, per hour, is $35.

You want to create a scale model for a building that will be 120feet tall and 40 feet wide. If you make the model 6 feet tall, how wide should it be?
Given:
Length of the building = 120 feet
Width of the building = 40 feet
Length of the model = 6 feet
To find:
Width of the model.
Solution:
The scale model similar to the original figure and the corresponding sides of the similar figures are proportional.
Let x be the width of the building.
[tex]\dfrac{\text{Length of the building}}{\text{Length of the model}}=\dfrac{\text{Width of the building}}{\text{Width of the model}}[/tex]
[tex]\dfrac{120}{6}=\dfrac{40}{x}[/tex]
[tex]20=\dfrac{40}{x}[/tex]
[tex]x=\dfrac{40}{20}[/tex]
[tex]x=2[/tex]
Therefore, the width of the model is 2 feet.

In right triangle ABC, m∠ B ≠ m∠ C. Let sin B = r and cos B = s.
What is sin C – cos C?
Draw and label a diagram.
sin A = CB / AB
cos B = CB / AB
sin A = cos B
2x - 1.3 = 5x
Can you solve for x and answer?
The value of expression sin C - cos C is,
⇒ r - s
What is mean by Triangle?Triangle is a three sided polygon, which has three vertices and three angles and which has sum 180 degrees.
Given that;
In right triangle ABC,
⇒ m∠ B ≠ m∠ C.
Let us assume that,
⇒ sin B = r
And, cos B = s.
Now, We get;
sin B = rh / h
= r
And, cos B = sh / h
= s
Hence, We can formulate;
sin C = sh / h = s
cos C = rh / h = r
Thus, We get;
⇒ sin C - cos C
⇒ r - s
Therefore, The value of expression sin C - cos C is,
⇒ r - s

She made eight 2 pointers
She made four 3 pointers
Step-by-step explanation:
2x + 3y = 28
x + y = 12 Multiply this equation by 2
2x + 2y =24
Write the first and third equations underneath each other,
2x + 3y = 28
2x + 2y = 24 Subtract.
y = 4
x + y = 12
x + 4 = 12 Subtract 4 from each side
- 4 -4
