Answer:
1) q = (sq rt 15 - 2) / 3
2) d = (sq rt 3 - 1) / 4
3) m = 15 * sq rt 3
Step-by-step explanation:
1.√3q + 2 = √5
we bring to the power of 2 each element
(√3q)^2+2^2=√5^2
3q+4=5
3q=4-5
q=1/3
2.
4d+1=√3
we do the same thing
16d^2+1=3
16d^2=2
d^2=2/16
d^2=1/8
d=√1/√8
3.
m/√3 -11=4
first we rationalise by multiplying the first fraction with √3
m√3 /3-11=4
now we can bring to the power of 2
3m^2/9-121=16
3m^2/9=137
m^2/3=137
m^2=411
m=√411

I need help to understand before my test today
Answer:
75 degrees
Step-by-step explanation:
All the angles within a triangle added together equals 180 degrees, so:
x + 25 + 2x - 5 + x = 180
add like terms
4x + 20 = 180
subtract 20 from both sides
4x = 160
divide by 4
x = 40
Now input 4 into the equation for C
2(40) - 5 = 80 - 5 = 75
Six students collect buttons for a project. The students have 10, 14, 15, 12, 13, and 14 buttons. They divide the buttons evenly so that each student receives the same number of buttons. How many buttons does each student receive?
Answer:
13 buttons
Step-by-step explanation:
The first step is to add the buttons received by the 6 students.
= 10 + 14 + 15 + 12 + 13 + 14
= 78 buttons
Therefore the number of buttons received by each students can be calculated as follows
= 78/6
= 13 buttons
Hence each student will receive 13 buttons

Which of the sets of ordered pairs represents a function? (1 point)
P = {(6, −7), (3, −2), (−9, 2), (−5, −7)}
Q = {(−7, 8), (4, −6), (−3, 1), (1, 5)}
Answer:
Conclusion:
Both sets represent the function.
Step-by-step explanation:
We know that a function relates an input to an output.For example, a certain plant grows 10 cm each year. Thus, the height of the plant is associated with its age using the function
h (age) = age × 10
Thus, if the age of the plant is 2 years, the height is:
h(10) = 2 × 10 = 20 cm
Set P
P = {(6, −7), (3, −2), (−9, 2), (−5, −7)}
The set P represents the function because the function relates an input to an output. In other words, here each input is related to exactly one output.
The x-values are 6, 3, -9, and -5.
Thus, there are no duplicated inputs or x-values.
Therefore, the set P of ordered pairs represents a function.Set Q
Q = {(−7, 8), (4, −6), (−3, 1), (1, 5)}
The set P represents the function because the function relates an input to an output. In other words, here each input is related to exactly one output.
The x-values are -7, 4, -3, and 1.
Thus, there are no duplicated inputs or x-values.
Therefore, the set Q of ordered pairs also represents a function.Conclusion:
Both sets represent the function.

To completely cover a cube,Joey uses a total area of 486 square inches of material. To the nearest whole cubic inch, what is the maximum volume the box could have? Pls help me and fast
Answer:
The maximum volume the cube could have is 729 cubic inches
Step-by-step explanation:
The total surface area of the cube equals the total area of material used.
Let A = total surface area of cube = 6L² where L = length of side of cube
Since A = total area of material used, A = 486 in²
So 486 in² = 6L²
L = √(486 in²/6)
= √81 in²
= 9 in
The volume of the cube V = L³ where L = length of side of cube
So, V = (9 in)³
= 729 in³
So the maximum volume the cube could have is 729 cubic inches.
The maximum volume that the box could have will be 729inches³.
Based on the information given, the first thing to do is to find the length of the shape. This will be:
Length = ✓(486/6)
Length = ✓81
Length = 9
Therefore, the volume of the cube will be:
= 9³
= 9 × 9 × 9
= 729 in³.

John runs the same amount each day (r). If he runs for 4 days this week write an expression to represent the amount he ran this week.
Answer:
[tex]r \cdot 4 = z[/tex]
Step-by-step explanation:
An expression means that we don't know enough to create an equation. So, this means we will mostly be using variables.
John runs r amount every day. We need to create an expression for if he runs r amount for 4 days.
[tex]r \cdot 4 = z[/tex]
r = how much he runs per day
4 = how many days he runs
z = how much he runs this week
This is your expression!
Answer:
r * 4 = a
Step-by-step explanation:
If John runs the same amount everyday (r) for the past four days, we can multiply 4 by r
r * 4
We don't have enough information to write the answer to the expression so in its place we can put a variable. (In this case, I chose a)
r * 4 = a
So a possible expression for this problem is r *4 = a
Hope this helps! Have a great day! :)

Each of three colored cups covers one of three objects. 1) The red cup is somewhere to the left of the white cup. 2) The coin is somewhere to the left of the bean. 3) The gray cup is somewhere to the right of the shell. 4) The bean is somewhere to the right of the gray cup. Under which color cup is the shell?
Answer:
Shell is under Red color cup
Step-by-step explanation:
We have 3 cups and 3 objects which they cover under them.
Taking into consideration (4) and (2) as they both describe the position related to bean
(4) Gray cup →Bean (right) (2) coin ← bean (left)
that means coin can either under Gray cup or left to gray cup.
Now
(1) Red ← White (left) (3) Shell → Gray (right)
This means if we consider coin to be left of gray cup then we can't place shell to the left of gray cup as required in (3)
so coin will be under gray cup
on forming the Color of cups and the coin below them
C1 C2 C3
Red Gray White

Shell coin Bean
So Shell is under Red color cup

Eric bought a ruler for $1.29 and an eraser for $0.39. He paid with $2.00. What is the correct amount of change he should get back?
Answer:
$0.32, so a quarter a nickel and 2 pennies
Step-by-step explanation:
Answer:
$0.32
Step-by-step explanation:
First, add $1.29+$0.39 to get the total amount of the transaction.
$1.29+$0.39 = 1.68
Then, subtract that from the amount paid.
$2.00-$1.68
= $0.32

find the length of sides in an isosceles triangle whose sides are 3x-0.4 & x+1.4 (equal sides) and not equal side is x+0.1
Answer:
The length of the sides are;
2.3, 2.3 and 1
Step-by-step explanation:
If the equal sides are 3x-0.4 and x + 1.4
This means these two are equal to one another
Thus;
3x-0.4 = x + 1.4
3x-x = 1.4 + 0.4
2x = 1.8
x = 1.8/2
x = 0.9
So the length of the sides are as follows;
3x - 0.4
3(0.9)-0.4 = 2.3
x + 1.4
= 0.9 + 1.4 = 2.3
And lastly
x + 0.1
0.9 + 0.1 = 1
