Max is designing a bedroom. The bedroom needs to be 30 cubic meters when finished. What might the dimensions be? Give two answers
Answer:
3.10 m
Step-by-step explanation:
The bedroom needs to be 30 cubic meters when finished.
We need to find the dimensions of the room.
The volume of a cube is given by :
[tex]V=a^3[/tex]
Where
a is the side of the cube
So,
[tex]a=(V)^{1/3}\\\\a=(30)^{1/3}\\\\a=3.10\ m[/tex]
So, the dimension of the room is 3.10 m.

(divide both sides by 3.14)
1296=r^2
(find sqr root of 1296)
36=r
to find the diameter with the radius, multiply radius by 2... 36*2= 72

What are the values of T and U?
Answer:
u+133°=180
u=180-133
u=47°
Answer:
U = 47
T = 86
Step-by-step explanation:
133 + U = 180 ( straight line)
or, U = 180 - 133
or, U = 47
Being isosceles triangle
47 + 47 +T = 180
or, 94 + T = 180
or, T = 180 - 94
or, T = 86

What is the equation of the line perpendicular to 3x+y=6 that passes through the
point (-6, -1)?
Answer: y = -1/3x - 3
Step-by-step explanation:
First, convert this equation into slope intercept form (y = mx + b where m is the slope and b is the y-intercept)
To convert this equation into slope-intercept form, all you have to do is subtract 3x from both sides to give you the equation y = 3x + 6Next, you need to find the slope of your new equation. The slope of a perpendicular line will have a slope that is the opposite reciprocal of the first slope, which means it will have the opposite sign and the fraction will be flipped (even whole numbers are a fraction - they are divided by 1)
Since the slope of the first equation is positive 3, you are going to change the sign to a negative and flip the fraction from 3/1 to 1/3, which gives you a slop of -1/3Now that you have your slop, you need to find your y-intercept. To do this, you use the point that you are given. In the previous step, you figured out the slope, so now you can enter that into your new equation. Then, plug the x-coordinate in for x and the y-coordinate in for y in the equation.
At this point, your equation is y = -1/3x + b. You can plug -6 in for x and -1 in for y to give you the equation -1 = -1/3(-6) + bThe next step is to solve the equation like you would any other equation.
Multiply -6 by -1/3 to get 2, then subtract 2 from -1 to get b = -3Lastly, create your new equation in slope-intercept form with the values you have found.

A survey was conducted to see how many phone calls people made daily. The results are displayed in the table below:
From the given frequency table,
Frequency represents the number of people who made the calls.
Total number of people who made the calls = 16 + 11 + 5 + 3 + 1
= 36
Number of people who made less than 13 calls = 16 + 11 + 5
= 32
Number of people who made at least 9 calls = 5 + 3 + 1
= 9
Percentage of people who made at least 9 calls = [tex]\frac{\text{Number of people who made at least 9 calls}}{\text{Number of people who made the calls}}\times 100[/tex]
= [tex]\frac{9}{36}\times 100[/tex]
= 25%
Difference in the number of people who made the calls between 5-8 calls than 13-16 calls = 11 - 3 = 8

The expressions a(8[tex]x[/tex] + 7) and 4x + 3.5 are equivalent What is the value of a? 50pts mark brainiest if right
Answer:
The expressions a(8x+7) and 4x + 3.5 are equivalent
Therefore, according to the above problem the equation is :---
[tex]a(8x + 7) = (4x + 3.5) \\ 8ax + 7a = 4x + 3.5[/tex]
By comparing the term, we get
[tex]8ax = 4x \\ 8a = 4 \\ a = \frac{4}{8} \\ \boxed{a = \frac{1}{2} }[/tex]
and,
[tex]7a = 3.5 \\ a = \frac{3.5}{7} \\ \boxed{a = \frac{1}{2} }[/tex]
The value of "a" is 1/2.Answer:
The expressions a(8[tex]x[/tex] + 7) and 4x + 3.5 are equivalent
Step-by-step explanation:
a(8x+7)=4x+3.5
8ax+7a=4x+3.5
let keep a=1/2
8/2x+7/2=4x+3.5
4x+3.5=4x+3.5

The amount of money, y, pizzeria K makes by selling x pizzas can be modeled by the equation y = 13x. The relationship of the amount of money pizzeria L makes is shown in the following graph. Which pizzeria makes more money per pizza?
Answer:
Step-by-step explanation:
Complete Question:
The amount of money, y, pizzeria W makes by selling x pizzas can be modeled by the equation y = 15x. The relationship of the amount of money pizzeria L makes is shown in the following graph.
Which pizzeria makes more money per pizza?
A. Pizzeria L makes more money per pizza.
B. Pizzeria W makes more money per pizza.
C. They make the same amount per pizza.
Answer:
B. Pizzeria W makes more money per pizza.
Step-by-step explanation:
The proportional relationship showing how amount of money made(y) is related to the amount of pizzas sold (x) for pizzeria W is given by the equation y = 15x.
the constant of proportionality/unit rate, k = 15.
This represents the amount in dollars, made per pizza.
So, Pizzeria W makes $15 per pizza.
For Pizzeria L, using any point on the line, say, (2, 24),
k = y/x = 24/2 = 12.
This represents the unit rate, which is the amount Pizzeria L makes per pizza.
Thus, Pizzeria L makes $12 per pizza.
We can conclude that, Pizzeria W makes more money per pizza.
