3. In ΔABC, AB = 5 inches and BC = 3 inches. Which of the choices represents all possible values for AC, in inches?
Answer:
2< AC<8
Step-by-step explanation:
For a triangle to exits sum of two sides must always be greater than the the third side
⇒ AC< AB+ BC =5+3=8 in
⇒AC<8 in
Also, the difference of the two sides must be smaller than the length of third side
⇒ AC> | AB-BC| = |5-3| =2
AC> 2 in
therefore, we can say 2< AC<8. Hence, AC can takes 3,4,5,6 values

Corey spent $17.00, inculding sales tax, on 2 sanwiches cost $5.25 each and the total sales tax was $0.92. What was the cost of each drink.
Answer:
Well to start you already know the sandwich cost 5.25 and the total sales tax .92.
To find the cost of each drink
5.25 x 2= 10.50
10.50+.92=11.42
17.00-11.42= 5.58
5.58/3= 1.86
So the cost per Drink is $1.86

What is the solution to the equation −4(2y − 4) − 4y = 4? (put number answer only)
Answer:
y=1
Step-by-step explanation:
Let's solve your equation step by step.
Step 1: Simplify both sides of the equation.
−4(2y−4)−4y=4
(−4)(2y)+(−4)(−4)+−4y=4(Distribute)
−8y+16+−4y=4
(−8y+−4y)+(16)=4(Combine Like Terms)
−12y+16=4
−12y+16=4
Step 2: Subtract 16 from both sides.
−12y+16−16=4−16
−12y=−12
Step 3: Divide both sides by -12.
y=1

PLSS HELP the length of a rectangle is 3 meters greater than 2 times the width the perimeter of a rectangle is 30 m what is the length of the rectangle
Answer:
Width: 4 meters. Length: 11 meters
Step-by-step explanation:
If you do it correctly, the length should be 3 more greater than 4*2. 4*2= 8 +3= 11. Your perimeter= 30 meters. 11+11 accounting for both long sides of the rectangle= 22. Accounting for both sides of the width, so 4*2=8 + our 22= 30 meters. Yw.
The length of the rectangle width 4 meters and length 11 meters.
If you do it correctly,
The length should be 3 more greater than

f(4) is just asking what the y value is when x=4 which is 1
f(-3) = -4
This has no minimum or maximum because the range is all real numbers (the y value goes to infintiy and negative infinity)
f(3)=6
f(0)= 3
This has a minimum because the lowest y value possible is not infinity (it's 2)

Question A:
The formula to find the hypotenuse is c²=a²+b²
So you would insert the numbers into the formula which would be c²=8²+6²
8²=64
6²=36
36+64=100
So c²=100
Then you want to find c on its own so you have to square root 100.
The square root of 100 is 10.
You have to use this method for the rest of the triangles.
The hypotenuse of the triangles are solved
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the measure of sides of the triangle are
a)
a = 8
b = 6
Now , From the Pythagoras Theorem , The hypotenuse² = base² + height²
c = √ ( 8 )² + ( 6 )²
c = √100 ≈ 10
b)
a = 11
b = 7
c = √170 ≈ 13.0
c)
a = 13
b = 6
c = √205 ≈ 14.3
Hence , the hypotenuse of the triangles are solved
