Answer:
B. 4
Step-by-step explanation:
Hypotenuse (h) = 5
base (b) = 3
perpendicular (p) = a = ?
We know by using Pythagoras theorem we get
p = √( h² - b²)
= √ ( 5² - 3²)
= √ (25 - 9)
= √16
= 4

Math question highschool
Answer:
3589.85763 meters
Step-by-step explanation:
Essentially, we must have e^(-0.00012h) = 0.65 since 0.65 = 65%
Taking natural log of both sides, we get
-0.00012h = -0.430782916
0.00012h = 0.430782916
h = 3589.85763

A ticket to see your favorite baseball team costs $43.13. That price decreases by $0.45 for every game lost during the regular season. What equation could you use to find the cost C of a ticket after L losses? Represent the total change in the cost of a ticket after the team loses 39 games. What is the price of a ticket after the team loses 39 games?
Answer:
$25.58
Step-by-step explanation:
39 * 0.45= 17.55
43.13 - 17.55= $25.58

Solve for x. Then find the side lengths of the triangle. If needed, round to the nearest tenth of a foot.
40 ft
Bx ft
6x ft
side lengths =
ft and
Answer:
The side lengths are 17.9 feet and 35.8 feet
Step-by-step explanation:
Given lengths are;
40 feet, 3x feet and 6x feet
As the given triangle is right angled,
a = 3x, b = 6x and c = 40
Using Pythagorean theorem;
[tex]a^2+b^2=c^2\\(3x)^2+(6x)^2=(40)^2\\9x^2+36x^2=1600\\45x^2=1600\\[/tex]Dividing both sides by 45
[tex]\frac{45x^2}{45}=\frac{1600}{45}\\x^2=35.55[/tex]
Taking square root on both sides
[tex]\sqrt{x^2}=\sqrt{35.55}\\x=5.96[/tex]
Side lengths = 3x = 3(5.96) = 17.9 feet
and
6x = 6(5.96) = 35.8 feet
Hence,
The side lengths are 17.9 feet and 35.8 feet
Answer:
x=6

A baker regularly uses flour to make pastries for the bakery at the beginning of the month of the Baker has a 25 pound bag of flour. Each week she uses 5 3/5 pounds of flour write an expression to represent the change in weight of the bag of flour over four weeks
Answer:
At the beginning, she has 25lb of flour.
Each week, she ses (5 + 3/5) pounds of flour.
Then after the first week, she has a total of:
W(1) = 25lb - (5 + 3/5)lb
After another week, she has:
W(2) = 25lb - (5 + 3/5)lb - (5 + 3/5)lb = 25lb - 2*(5 + 3/5)lb
and so on.
if x represents the number of weeks, the equation is:
W(x) = 25lb - x*(5 + 3/5)lb
where x can be {0, 1, 2, 3, 4}
That is the equation that represents the change in the weight for the first four weeks.

the first player to the tenth player without spilling within the allotted time. After the task, the team captain measured
the water collected using a measuring cup. Team Narra collected 1.402 liters while Team Mahogany collected 1.045
liters of water. Which team got more water?
Solution:
Answer:
Team Nara collected more water
1.402 > 1.045
so team nara wins
Team Narra is collected more amount of water than Team Mahogany and this can be determined by using the given data.
Given :
Team Narra and Team Mahogany underwent a water challenge.Their task was to transfer the water in a cup from the first player to the tenth player without spilling within the allotted time.Team Narra collected 1.402 liters while Team Mahogany collected 1.045 liters of water.The following steps can be used to determine which team collected more amount of water in a cup:
Step 1 - Remember that the amount of water collected by Team Narra is 1.402 liters.
Step 2 - Also remember that the amount of water collected by Team Mahogany is 1.045 liters.
Step 3 - Now, compare both quantities of water.
1.045 < 1.402
So, according to the given data Team Narra is collected more amount of water than Team Mahogany.

Answer:
7= 2 4/5 8=2/21 9= 6 3/7 10= 1/6 11= 7/5 12=77/90
Step-by-step explanation:
3 1/5= 16/5-2/5=14/5 which equals to the same thing to 2 4/5
5/3= 35/21
11/7= 33/21
35/21-33/21= 2/21
3 3/4=15/4 times 12/7 straight ahead which is 180/28 equals to the same thing as 45/7 = 6 3/7
1/5 times 7/1 so u flip it over as u can see which is 7/5
2 1/5= 11/5 2 4/7= 18/7 11/5 times 7/18=77/90
Triangle K L J is cut by line segment N O. Line segment N O goes from side L K to side L J. The length of L N is (x minus 3) inches, the length of N K is (x + 2) inches, the length of L O is (x minus 4) inches, and the length of O J is x inches. Which value of x would make Line segment N O is parallel to line segment K J? 1 6 8 10
Answer: x= 8
Step-by-step explanation:
According to the converse of basic proportionality theorem,
If in ΔABC , DE is a line drawn from AB to AC such that [tex]\dfrac{AD}{DB}=\dfrac{AE}{EB}[/tex]
then, DE is parallel to the third side BC.
Applying converse of basic proportionality theorem, to get NO parallel to KJ, we must have
[tex]\dfrac{LO}{OJ}=\dfrac{LN}{NK}\\\\\Rightarrow \dfrac{x-4}{x}=\dfrac{x-3}{x+2}\\\\\Rightarrow\ (x-4)(x+2)=x(x-3)\\\\\Rightarrow\ x^2-2x-8=x^2-3x\\\\\Rightarrow\ -2x+3x=8\\\\\Rightarrow\ x=8[/tex]
Hence, the value of x should be 8, so that Line segment N O is parallel to line segment K J.
