i think
Can you help me with these two thank you
Answer:
2. 19.47 in
3. 153.86 square centimeters
Step-by-step explanation:
2. The circumference of a circle is π times the diameter, so in this case it is 6.2 * 3.14 = 19.47 in (rounding to nearest hunderdth).
3. The area of a circle is π/4 times the diameter squared, so in this case it is 14^2 * 3.14 / 4 = 153.86 square centimeters.
Find the value of x. Write your answer in simplest form. need help quick pls
Answer:
The value of x is approximately 5
Step-by-step explanation:
Answer:
x=6.36
Step-by-step explanation:
In a right triangle where the angles are 45, 45 and 90, the hypotenuse is equal to [tex]\sqrt{2}[/tex] multiplied by the length of the legs. Knowing this, we can set up the following equation:
[tex]9=x\sqrt{2}[/tex]
Multiply both sides by [tex]\sqrt{2}[/tex]
[tex]9\sqrt{2} =x\sqrt{2}*\sqrt{2}\\9\sqrt{2} =2x[/tex]
Divide both sides by 2
[tex]\frac{9\sqrt{2}}{2}=\frac{2x}{2}\\\frac{9\sqrt{2}}{2}=x[/tex]
[tex]x=6.36[/tex] (this answer is approximate)
Therefore, x is equal to 6.36.
I hope this helps!

Can you answer number 6 please
Answer:
No, the triangles are not similar.
Step-by-step explanation:
For ΔNOP, since all triangles' angles equal 180°, to find the missing angle you subtract the given angles from 180
180-70=110, 110-58=52 ∠N = 52°
since ΔQRS does not have any angle measures of 58° or 52°, the triangles are not similar becasue similar triangles have congruent angles.

A video rental store charges a $20 membership fee and $2.50 for each video rented.
Write a linear equation to model this situation.
Tell what each variable represents.
Answer:
2.5x + 20 = y
Step-by-step explanation:
first, assign a variable to each unknown:
since we don't know how many videos were rented, that can be x, and we don't know the person's total cost, which can be y
x = number of videos rented
y = total cost
so there's always a $20 that's added on as a membership fee, which means that theres going to be a + 20 somewhere.
So, the equation is 2.5x + 20 = y

What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
To find square feet of flooring are needed to cover the entire floor of Bedroom 1.
Here, We have;
1 in = 4 feet
Hence, Length of bedroom 1 = 8 feet
Width = 4 feet
Thus, The area of Bedroom 1 is,
⇒ 8 x 4 = 32 feet²
Hence, The area of Bedroom 1 is,
⇒ 32 feet²

The triangular prism above has been created with two equilateral triangles and three congruent rectangles the height of the triangle is 3.5 inches find the surface area of the triangular prism
Answer:
108 inches square.
Step-by-step explanation:
Here
base= b= 4 inches
height = h=w= 3.5 inches
and length = l= 9 inches
The surface area is the total area of all the sides of the prism. So the area of the 2 triangles is given by
Area of the 2 Δs= b* h= 4*3.5= 13.5 inches square
Area of the 3 rectangles = l*w(3)= 3( 9*3.5)= 94.5 inches square.
Total area = 13.5 + 94.5 = 108 inches square
This can be found by applying another formula.
Surface area of the triangular prism = bh + ( s1+s2+s3) H
= 4*3.5 + (9+9+9)3.5
= 13.5 + 94.5= 108 inches square.
where H is the width of the recatngles which is equal to the height of the triangles.

Solve: 3n - 6 = -8(6 +5n)
and explain how to solve it
Answer:
Step-by-step explanation:
First use distributive property: a(b + c) = a*b + a*c
3n - 6 = -8(6 + 5n)
3n - 6 = 6 * (-8) + 5n *(-8)
3n - 6 = -48 - 40n
Now add 40n to both sides
3n - 6 + 40n = -48 - 40n + 40n
43n - 6 = -48
Now add 6 to both sides
43n - 6 + 6 = -48 + 6
43n = -42
n = -42 /43
Answer:
0.98
Step-by-step explanation:
3n-6=-8(6+5n)
3n-6=-48-40n
3n=-48-40n+6
40n+3n=-42
43n=-42
n=0.98 (I rounded it)

Reggie is deciding when to go bowling with his friends. Friday night is glow-bowling night,
with 5 glow-bowling games for $22.50. But the early-bird special on Saturday morning offers
8 games for $30. How much more does glow-bowling cost per game?
Answer:
glow bowling costs $0.75 more per game
Step-by-step explanation:
1. divide $22.50 by 5 games to find the price per game for glow-bowling, which comes out to $4.50
2. divide $30.00 by 8 games to find the price per game for the early-bird special, which comes out to $3.75
3. subtract $3.75 (early-bird bowling) from $4.50 (glow-bowling) and it = $0.75
4.50-3.75=0.75
Answer: The answer is 0.75
