the length of each side of a square increases by 40%. by what percent does the area of the square increase?
Answer:
96%
Step-by-step explanation:
If you substitue values for the sides of the square, you can easily solve this problem.
If the side of each square was 10, then the area of the square would be 100. A 40% increase in side length would mean 10×.4 = 4 --> 10+4= 14.
14 would be your new side length meaning that the area would be 196.
From this, you can see that there is an increase by 96 from the original to the 40% increase. Since the value was initially 10, we can turn the 96 increase into 96 percent.
Answer:
40% iincrease
Step-by-step explanation:
A=l^2 (area of a square) let the unknown dimensions be x Area of the original square without change=(x^2) Area of the square undergoing change =(1.4x^2) thus,% change=new-old/old*100% 1.4-1.0=0.4*100=40%

Step-by-step explanation:
2 sides of the parallelogram are 13cm and the other 2 sides are 16cm
Perimeter of the parallelogram
= 2 * 13cm + 2 * 16cm
= 26cm + 32cm
= 58cm.

Miguel and three of his friends went to the movies. They originally had a total of $40. Each boy had the same amount of money and spent $7.50 on a ticket. How much money did each boy have left after buying his ticket? Write and solve an equation that represents he situatio.
Answer:
x = (40/4)-7.50
x= (10)-7.50
x = 2.50
Step-by-step explanation:
each boy had 2.50 left after the movie because miguel went with 3 other boys, which makes four of them all together. If they had forty dollars all together and all had the same amount of money, you can determine that amount by dividing forty(total money) by 4(number of boys). Which gets you to the answer of ten dollars each. Then you subtract the ticket cost(7.50) from 10 dollars, which gets you to 2.50 left over.

The baseball team has a double-header on Saturday. The probability that they will win both games is 42%. The probability that they will win the first game is 60%, What is the probability that the team will win the second game given that they have already won the first game?
The probability that the team will win the second game given that they have already won the first game is 7/10
Event win in the 1st game is represented with A
Event win in the 2nd game is represented with B
In the question
i. The probability that they will win both games is P(AnB) = 42%
ii. The probability that they will win the first game is P(A) = 60%
The probability that the team will win the second game given that they have already won the first game is:
P(B/A) = P(BnA) / P(A)
P(B/A) = P(AnB) / P(A)
From the question
P(B/A) = 42% / 60%
P(B/A) = 0.42 / 0.60
P(B/A) = 7/10
In conclusion: The probability that the team will win the second game given that they have already won the first game is 7/10

Answer:
x = 25
Step-by-step explanation:
From the picture attached,
ΔABC and ΔADE are the similar triangles.
Therefore, their corresponding sides will be in the same ratio.
[tex]\frac{\text{AB}}{\text{AD}}=\frac{\text{AC}}{\text{AE}}=\frac{\text{BC}}{\text{DE}}[/tex]
[tex]\frac{\text{AB}}{\text{AD}}=\frac{\text{BC}}{\text{DE}}[/tex]
And AB = AD + DB
= 2(AD) [Since, AD = DB]
By substituting these values,
[tex]\frac{\text{2AD}}{\text{AD}}=\frac{\text{34}}{\text{(x-8)}}[/tex]
2 = [tex]\frac{34}{x-8}[/tex]
x - 8 = [tex]\frac{34}{2}[/tex]
x - 8 = 17
x = 17 + 8
x = 25

Lin found the area of a rectangle with a of length 5 in and a width of 3 inches, to be 15 square inches. Lin creates another rectangle that is a scaled copy with a scale factor of 2. What is the area of the new rectangle? How did you find it?
Answer:
60in^2Step-by-step explanation:
Step one:
given data
lenght L= 5in
width W= 3 in
area= L*W
area= 5*3= 15in^2
Step two:
The rectangle was scaled by 2, this means that the dimensions were doubled
therefore the lenght and width will be
L=5*2= 10
W=3*2= 6
hence the area is
Area= 10*6= 60in^2

Three vertices of parallelogram DEFG are
D(0, 2), E(-1, 5), and G (4, 0). Find
the coordinates of F.
Answer:
F(3,3)
Step-by-step explanation:
The coordinate of F is (3, 3).
GivenThree vertices of parallelogram DEFG are D(0, 2), E(-1, 5), and G (4, 0).
What is the formula to find the midpoints?Diagonals of a parallelogram bisect each other, meaning they divide each other into equal parts.
The formula is used to find the midpoints are as follows;
[tex]\rm \dfrac{x_1+x_2}{2} , \ \dfrac{y_1+y_2}{2}[/tex]
Let (x, y) = coordinates of vertex F.
DF and EG are diagonals of parallelogram DEFG, therefore:
The midpoint of DF = midpoint of EG
Then,
The midpoint of D(0, 2) and F(x, y) is;
[tex]\rm \dfrac{x_1+x_2}{2} , \ \dfrac{y_1+y_2}{2}\\\\\dfrac{0+x}{2}, \ \dfrac{2+y}{2}[/tex]
The midpoint of E(-1, 5) and G(4, 0) is;
[tex]\rm \dfrac{x_1+x_2}{2} , \ \dfrac{y_1+y_2}{2}\\\\\rm \dfrac{-1+4}{2} , \ \dfrac{5+0}{2}\\\\\dfrac{3}{2}, \dfrac{5}{2}[/tex]
Comparing the equation;
[tex]\rm \dfrac{0+x}{2} = \dfrac{3}{2}\\\\\dfrac{x}{2} = \dfrac{3}{2}\\\\x=3[/tex]
[tex]\rm \dfrac{2+y}{2} =\dfrac{5}{2}\\\\2+y =5\\\\y = 5-2\\\\y =3[/tex]
Hence, the coordinate of F is (3, 3).
