Answer:
h = 13ft
Step-by-step explanation:
We can assume that the triangles are similar, so:
5 ft is to 26 ft as 2.5 ft is to h ft.
Which can be set up like this:
[tex]\frac{5}{2.5}=\frac{26}{h}[/tex]
We can cross multiply:
5h = (2.5) (26)
5h = 65
h = 13ft
a bag contains 4 blue and 6 green marbles. two marbles are selected at a random from the bag. if the first marble is not replaced before the second marble is drawn
Answers
Answer:
4 ÷ 10
Step-by-step explanation:
The computation of P is shown below:
If we add two marbles i.e.
= 4 + 6
= 10 marbles
Now if we draw the second marble
P(blue) = Blue marbles ÷ total marbles
= 4 ÷ 10
In the other case
P( blue second given a green first) = 4 ÷ 10

Step-by-step explanation:
Problem One
Perimeter is in meters not square meters. The equation is
2*(6.8+x) + 2*12.5= 47 Remove the brackets. Combine like terms
13.6 + 2x + 25 = 47
38.6 + 2x = 47 Subtract 38.5 from both sides
2x = 47 - 38.6
2x = 8.4 Divide by 2
x = 4.2
Answer D
Problem 2
This problem is asking that you calculate the perimeter of a swimming pool.
The two semicircles on the ends make a whole circle.
The diameter of the semicircles is obtained from the difference of the two given lengths.
The rectangle has a length of 12. The length of the rectangle and the 2 semicircles is 16. The difference is 4. You could divide this by 2 to get the radius. I would just leave it as the diameter.
So the perimeter is pi*d + 2 * 12 [there are 2 lengths]
Perimeter = 4*pi + 24
Perimeter = 12.56 + 24
Perimeter = 36.56
Answer A
Problem 3
This is the circle inside the square.
The radius of the circle = 9
The diameter of the circle and the length of square's side = 2*9 = 18
The area of the square = s^2 where s = 18
The area of the square = 18^2 = 324
The area of the circle = pi * 9^2 = 3.24 * 81 = 251.34
The area of the Shaded area = 324 - 251.34 = 69.66
Answer C
Problem 4
b1 = 5
b2 = 11.5
h = 4.5
Formula
Area = (b1 + b2 ) * 4.5/2
Area = (5 + 11.5) * 4.5 /2
Area = 16.5 * 4.5 / 2
Area = 74.25/2
Area = 37.125

Answer:
The solution of the first image is: b = √48
The solution of the second image is: c = √125
Step-by-step explanation:
Here we have two triangle rectangles, first, we need to remember the Pythagorean theorem.
For a triangle rectangle with cathetus A and B, and a hypotenuse H, we have the relationship:
A^2 + B^2 = H^2
Where H is the side that is opposite to the right angle (the angle of 90°)
In the first image, we can see that the hypotenuse is equal to 8, and one cathetus is equal to 4.
We want to find the value of b, that is the other cathetus.
Then we have:
4^2 + b^2 = 8^2
b^2 = 8^2 - 4^2
b^2 = 48
b = √48
Second image:
in this case, c is the hypotenuse, a and b are the cathetus.
We know that:
a = 5, b = 10
Then we have the equation:
a^2 + b^2 = c^2
Now we can replace the above values:
5^2 + 10^2 = c^2
25 + 100 = c^2
125 = c^2
√125 = c

You had $24 to spend on three notebooks. After buying them you had $12. How much did each notebook cost?

Answers
Answer:
Each notebook would cost around $4
Step-by-step explanation:
24-12=12
seeing how you spent $12 on buying 3 books you'd divide
12÷3=4
meaning each book would cost around $4
Answer:
Each notebook cost $
Step-by-step explanation:
Hi :)
If the three books in total cost $12, then that means she had $12 leftover.
The equation:
3x + 12 = 24
-12 on both sides
3x = 12
divide by three on both sides
x = 4

At the end of the season, 4 basketball teams in a league are having a pizza party at a restaurant.
Team Number of People
Sharks 17
Wolves 21
Tigers 20
Hawks 17
Coaches 9
The restaurant manager suggests that they order one pizza for every 6 people. How many pizzas
should they order?
Answers
First, add up the numbers of players on each team and the coachesto get the total number of people eating.
17 + 21 + 20 + 17 + 9 = 84
Then, you can divide 84 by 6 to see how many pizzas: 84/6 = 14
If you’re teacher wants you to set it up as a ratio, it’s 6/1 = 84/x
Then you cross-multiply:
6x = 84
Divide both sides by 6
x = 14

The temperate in Anchorage, Alaska at 9am was at -2°F. At 9pm the temperature decreased 7°F. Write an expression that represents the difference between the temperature from 9am to the resulting temperature at 9pm. How do I write the expression?
Answers
Im calling temperature T and time t for our equation but they can just as easily be Y and X
In 12 hours time the temp decreased 7 degrees so to get the slope we went down 7 and over 12 making it -7/12 (since we went down)
The at the starting point of t=0 it’s already -2 F making that our “y intercept” T intercept in this case
y=mx +b
In our case y=T x=t m=-7/12 and b= -2
Replace them to get
T=(-7/12)t-2
