Two sides of a triangle are equal in length. The third side of the triangle is 3 more than the equal sides. If the perimeter of the triangle is 48, what is the length of the longest side?
Show work
Answer:
18
Step-by-step explanation:
The two smaller sides are 15 and the larger one is 18
Answer:
18Step-by-step explanation:
Let the length of equal sides be x, then the perimeter is:
2x + (x + 3) = 483x + 3 = 483x = 45x = 15The longest side is:
15 + 3 = 18Would the circled area be an interior or exterior angle? Pls help!!!
Answer:
interior angle

What is the standard deviation of the following data set?
{14, 26, 40,52}
Your answer:
N
11.12
13.78
15.6
14.32
Answer:
D. 14.32
Step-by-step explanation:
The formula for standard deviation is:
[tex]SD = \sqrt{\frac{\sum | x-\mu|^2}{N}}[/tex]
The mean μ is 33.
The (x minus μ) squared are 361, 49, 49, 361 respectively.
So that the SD = [tex]\sqrt{\frac{820}{4}} \approx 14.31782...[/tex]
3 lemons cost $0.99. At this rate, how much would 8 lemons cost?
Step-by-step explanation:
3 lemons = $0.99
=> 8 lemons = $0.99 * (8/3) = $2.64.
8 lemons cost $2.64.
Answer:
2.64$ for 8 lemons.
Step-by-step explanation:
3 lemons = 0.99$
1 lemon = 0.99/3
= 0.33
Cost for 8 lemons = 0.33 x 8
= 2.64$

25-[20-{10-(7-5-3)}]=
Answer:
16
Step-by-step explanation:
When there are more than 1 brackets , there is a specific order of opening those brackets. First we open the bar , then round brackets , then curly brackets & then square brackets.
Using the order , let's solve this.
25-[20-{10-(7-5-3)}]
=> 25-[20-{10-(7 - 8)}]
=> 25-[20-{10 - (-1)}]
=> 25-[20- {10 + 1} ]
=> 25-[20 - {11}]
=> 25 - [ 20 - 11 ]
=> 25 - [9]
=> 25 - 9
=> 16
Consider the intersecting lines shown. Which of the following statements is true?
Question 10 options:
A)
∠y ≅ ∠z
B)
∠x ≅ ∠y
C)
m∠x + m∠y = 180°
D)
m∠x + m∠y = 90°
Answer:
C. m∠x + m∠y = 180
Step-by-step explanation:
The two straight line in the diagram intersect each other to form two pairs of vertical angles. These are <x and <z, and <y and w.
The only statement from the given options that is true is m∠x + m∠y = 180.
This is because they are angles in a straight line. The sun of angles in a straight line is 180°.

Rachel drew the two graphs below. Graph R On a coordinate plane, a line goes through points (0, 0) and (2, 1). Graph S On a coordinate plane, a line goes through points (0, 0) and (1, 2). Rachel says that Graph R has a greater constant of variation than Graph S. Which statement explains whether Rachel is correct? Rachel is correct; Graph S is nonproportional. Rachel is correct; Graph R goes farther along the x-axis. Rachel is not correct; both graphs go through the origin and have the same constant of variation. Rachel is not correct; Graph S is steeper than Graph R.

What is Exterior angles theorem?
Answer:
Exterior Angle Theorem
Step-by-step explanation:
An exterior angle of a triangle is formed by any side of a triangle and the extension of its adjacent side. The Exterior Angle Theorem states that An exterior angle of a triangle is equal to the sum of the two opposite interior angles.

Answer:
slope = 4/1 or 4
Step-by-step explanation:
Answer: 4
Step-by-step explanation:
Use the slope formula. change in y/change in x. The change in y is 4 because if your subtract the y coordinate 4 from the y coordinate 8, you get 4. The change in x is 1 because if you subtract the x coordinate 2 from the x coordinate 3, you get 1. 4 (change in y)/1 (change in x) is 4. Hope this helps!

Answer:
5) x = 21, y = -13
6) x = 20, y = -2
I don't know how to get #7, I'm sorry.
Step-by-step explanation:
5) 4x - 3(8 - x) = -3
4x - 24 - 3x = -3
+24 +24
4x - 3x = 21
x = 21
y = 8 - 21
y = -13
6) x + 3y = 14
-3y -3y
x = -3y + 14
-5(-3y + 14) + 6y = -28
15y + 14 +6y = -28
21y + 14 = -28
-14 -14
21y = -42
÷21 ÷21
y = -2
x + 3(-2) = 14
x + -6 = 14
+6 +6
x = 20

The weight of body is 420N. calculate its mass.
Answer:
mass = 42 kg
Step-by-step explanation:
We know that we have the formula that
W = m * g
Then
given
weight (w) = 420
g = 10 m/s²
then
W = m* g
420 = m * 10
m = 420/10
m = 42 kg
Hope it helps :)
Answer:
Step-by-step explanation: weight = 420N
mass= ?
we know,
weight = mass . acceleration due to gravity
or, 420 = mass . 9.8
therefore mass = 42.85 kg

Answer:
30.8, 37
Step-by-step explanation:
First, we know that the angles in a triangle add up to 180, so 180-75-48= m∠G=57°. Then, using sohcahtoa, we have tan(G) = DF/FG = DF/20. tan(G) ≈ 1.54, so 20(1.54)=DF≈ 30.8
Next, using sohcahtoa, we have cos(G) = FG/DG = 20/DG. cos(G)≈0.54, and 20/0.54=DG ≈ 37
