What is the length of BC in the right triangle below?
Answer:
Option A
Step-by-step explanation:
Use the Pythagoras Theorem
Hypotaneous² = base² + height²
BC² = AB² + AC²
BC = √ (AB² + AC²)
BC = √ (12² + 16²)
BC = 20
Answer:
20
Step-by-step explanation:
Here's your solution
=> in a right angle traingle
BC^2 = AB^2 + AC^2
=> BC^2 = 16^2 + 12^2
=> BC ^2 = 256 + 144
=> BC^2 = 400
=> BC = √400
=> BC = 20

find the area of the shaded part
Answer:
Step-by-step explanation:
the easiest thing to do is to make the half squares which you have 4 into 2 whole squares then base times height
4x3=12
Answer:
26cm²
Step-by-step explanation:
Alrighty, let's go count squares:
On the top row, there's 4 (adding the halves together), on the second row there's 5, and on the bottom row there's also 4, so we add that all together to get:
4 + 5 + 4 = 13
But, because each square is 2 cm, we have to multiply:
13 x 2 = 26
So, the area of the shaded section is 26cm²
hope this helps:)

A spinner is divided into equal sections, each labeled with a number between 1 and 5? Over the course of 150 spins, what is the best estimate of how many times you would expect that the hand of the spinner will stop on a 3? Need it kinda fast but take your time.
Answer:
30 times
Step-by-step explanation:
The computation of the number of times that expected to stop on 3 is as follows:
Since there are 150 spins
And, each labeled with a number that lies between 1 and 5
So the number of times should be
= 150 ÷ 5
= 30 times
Hence, the number of times would be 30

Raul uses a credit card to take out a 3-year loan of $4500 at a rate of 15% to purchase
carpeting for his house. What will be the total amount he will repay for this loan?
Answer:
Amount of loan pay = $6.840 (Approx.)
Step-by-step explanation:
Given:
Amount of loan borrow = $4,500
Rate of interest = 15% = 0.15
Number of year = 3 year
Find:
Amount of loan pay
Computation:
Future value = Present value[1+r]ⁿ
Amount of loan pay = Amount of loan borrow[1+r]ⁿ
Amount of loan pay = 4,500[1+0.15]³
Amount of loan pay = 4,500[1.15]³
Amount of loan pay = 4,500[1.52]
Amount of loan pay = $6.840 (Approx.)

Step-by-step explanation:
a packing box is 3.5 feet by 1.4 feet by 1.8 a box that is 3.1 feet by 1.1 feet by 1.4 feet is placed inside the first box the rest of the box is filled with packing foam how many cubic feet does the packing foam take up
The packing foam takes up approximately 4.606 cubic feet of space in the larger box.
To calculate the volume of the packing foam, we need to determine the volume of the larger box and subtract the volume of the smaller box.
The volume of the larger box is given by length × width × height, which is 3.5 feet × 1.4 feet × 1.8 feet = 8.82 cubic feet.
Similarly, the volume of the smaller box is calculated as 3.1 feet × 1.1 feet × 1.4 feet = 4.214 cubic feet.
To find the volume of the packing foam, we subtract the volume of the smaller box from the volume of the larger box:
8.82 cubic feet - 4.214 cubic feet = 4.606 cubic feet.

The equation is A = - ( 1/2) [ x - 12 ]
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be A
Now , the value of A is A = - ( 1/2 )x + 6
Now , on factorizing the given expression , we get
On taking the common term as - ( 1/2 )
A = - ( 1/2 )x + 6
A = - ( 1/2 ) [x - ( 2 x 6 ) ]
On simplifying the equation , we get
A = - ( 1/2 ) [ x - 12 ]
Therefore , the value of A is A = - ( 1/2 ) [ x - 12 ]
Hence ,The equation is A = - ( 1/2) [ x - 12 ]

Dr. Garica is twice as old as his son. Twenty years ago he was 4 times as old as his son was then. How old are they now?
Answer:
Let's let g = Dr. Garcia's age and s = his son's age.
g = 2s, right?
20 years ago, Dr. Garcia was g - 20 years old. He was also 4(s - 20), 4 times his son's age 7 years ago.
g - 20 = 4(s - 20)
g - 20 = 4s - 80
In the first equation, we have g = 2s. We are going to substitute this g into the second equation.
2s - 20 = 4s - 80
60 = 2s
s = 30
So, his son is 30 and Mr. Garcia is 60. 30 x 2 = 60.
20 years ago, his son would have been 10 and Mr. Garcia would have been 40. 10 x 4 = 40.
Step-by-step explanation:
Brainliest?
Answer:
Dr. Garcia's age is 60, and his son's age is 30.
Step-by-step explanation:
Let x be Dr. Garcia's age, and y his son's age.
1. Dr. Garcia is twice as old as his son
x = 2 y
2. Twenty years ago, he was 4 times as old as his son was then
x - 20 = 4 (y - 20)
Substitute x in 2 and solve for y:
2 y - 20 = 4 (y - 20)
2 y - 20 = 4 y - 80
- 20 = 2 y - 80
60 = 2 y
y = 30
Put y back into 1:
x = 2 (30)
x = 60
So Dr. Garcia's age is 60, and his son's age is 30.
