If BC = 15 and DA = 4, what is the length of DE
Answer:
Step-by-step explanation:
{y2+8y−128=0x=34⋅(y+4) ... The two right triangle are similar, so: BDAB=DEAC. From this, I obtain: ... AC=3x AB=4x (3x)²+(4x)²=225 x=3 BD=8 AB/AC=BD/DE 12/9=8/DE DE=6.
The length of segment DE in the given triangle is 6 units.
What are trigonometric ratios?Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle.
Given that, a right-angled triangle ABC, with a segment DE, where tan B = 3/4, BC = 15 and DA = 4
Since, tan B = 3/4
Cos B = 4/5
Cos B = AB / BC
therefore,
4/5 = AB / 15
AB = 12
BD = AB - AD = 12-4
BD = 8
Now, Tan B = 3/4
DE / BD = 3/4
DE / 8 = 3/4
DE = 6 units
Hence, the length of segment DE in the given triangle is 6 units.

i need help plz : Look at the representations shown in the Math Notes box for this lesson (“Representations of Portions”). Write a fraction and a percent for the shaded portion of each one.
plz help will give brainliest
Step-by-step explanation:
Hey there!!!!
Your required answer is option A.
The reason is.
When we solve it through elimination method we need to multiply second equation by "2" and then subtract to get "-4y" in 1st equation and "+4y" in 2nd equation cancelled.(As when we multiply equation 2 by 2 and subtract we get "-2y" as "+4y".)
So, it the equation seems like,
[tex]12 {x}^{2} + 4 {y}^{2} = 22[/tex]
Now, this equation is made after multiplying it by 2 and subtracting the 1st and 2nd equation to solve the equation s.
So, the answer is option A.

10. A movie theater sells 3 different sizes of popcorn: small, medium, and large. An order of popcorn comes with 4 different topping choices: butter, cheese, caramel, or salt. [4 points] How many unique ways can you order a bag of popcorn? (You can only select one topping.) Ans:_ What is the probability that a randomly selected popcorn is large with either butter or salt?
Answer: 12
Step-by-step explanation:
The answer is 12 because:
sizes are 3
toppings are 4
Using the Fundamental Counting Principal you multiple the selections
( 3 x 4=12)
So just learn the fundamental counting principal and it'll be easier. :)
The number of unique ways that you can order a bag of popcorn if you can only select one topping is 12 ways.
How do solve probability combinations?Combinations in probability refer to sequences of outcomes where the order does not matter.
Combinations are a way to calculate the total outcomes of an event where the order of the outcomes does not matter. To calculate combinations, we will use the formula nCr = n! / r! × (n - r)! where n represents the total number of items, and r represents the number of items being chosen at a time.
We are given the 3 different sizes of popcorn as;
Small
Medium
Large
Now, we are told that an order of popcorn comes with 4 different topping choices. Thus;
A number of unique ways that you can order a bag of popcorn are;
N = 3×4 = 12 unique ways

Woodley Stadium has nine gates with two ticket booths at each gate. If each ticket booth can process 600 fans per hour, what is the stadium's maximum ingress throughput?
Answer:
10,800
Step-by-step explanation:
9*2= 18
18*600=10,800
10,800 is the stadium's maximum ingress throughput.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
Given, Woodley Stadium has nine gates with two ticket booths at each gate.
So, the total number of booth's at Woodley stadium = 9*2
the total number of booth's at Woodley stadium = 18
Since each ticket booth can process 600 fans per hour
Thus,
the stadium's maximum ingress throughput = 18 *600
the stadium's maximum ingress throughput = 10,800
Therefore, 10,800 is the stadium's maximum ingress throughput.

represents the commission and P represents the purchase price of the car.
Jack sold two cars last weekend, one for $115,075 and the other for $21,640. Find his total commission.
Jack's commission=
Answer:
for first car
c = 250 + 0.02*$115,075 = 2551.5
for second car
c= 250 + 0.02*$21,640 = 682.8
total commission= 2551.5 +682.8 = 3234.3

Area of the smaller square = s²
Now, The area of the frame
= Area of the larger square - Area of the smaller square
= 12² - s²
Hence, the expression represents the area of the frame in square inches is 12² - s².
