Answer: 6
[tex]\sqrt{36}[/tex] = 6
Answer: 6
Step-by-step explanation: Divide the number by your guess. Now you have two numbers that multiply to get your original number. Take the average of these two numbers. This becomes your second guess for the square root.
PLS HELP Select all the expressions that represent the total area of this rectangle.
Answer:
E and D
Step-by-step explanation:
The area of a rectangle is length x width. In this case, that's (12+s) x 1/3
This can be re-written as 1/3(12+s)
D is 1/3s + 4 which is what happens when you multiply 1/3 by 12 which = 4 and multiply 1/3 by s which = 1/3s. So the answer is 1/3s+4.

Mr. Wright needs to buy a water tank for his classroom. The tank must fit inside a storage box that is shaped like a cube with side lengths of 20 feet. Water tanks are available in cylinders, cones, square pyramids, and spheres. Mr. Wright wants to buy the tank that has the largest capacity… What shape should he buy?
Answer:
square pyramids
Step-by-step explanation:
Square pyramids because they have corners and the storage box is shaped like a cube. If he gets things with rounded edges, then there will be empty space between each water tank.

f(x)=2x^3+ax^2-37x-60
The binomial x-4 is a factor of f(x). Find the value of a.
Given:
The function is
[tex]f(x)=2x^3+ax^2-37x-60[/tex]
The binomial [tex]x-4[/tex] is a factor of f(x).
To find:
The value of [tex]a[/tex].
Solution:
If [tex]x-c[/tex] is a factor of f(x), then [tex]f(c)=0[/tex].
It is given that, [tex]x-4[/tex] is a factor of f(x), then [tex]f(4)=0[/tex].
We have,
[tex]f(x)=2x^3+ax^2-37x-60[/tex]
Substituting x=4, we get
[tex]f(4)=2(4)^3+a(4)^2-37(4)-60[/tex]
[tex]f(4)=2(64)+a(16)-148-60[/tex]
[tex]f(4)=128+16a-208[/tex]
[tex]f(4)=16a-80[/tex]
Now,
[tex]f(4)=0[/tex]
[tex]16a-80=0[/tex]
[tex]16a=80[/tex]
[tex]a=\dfrac{80}{16}[/tex]
[tex]a=5[/tex]
Therefore, the value of a is 5.
A rhombus has side of length 60 units each and the lengths of its perpendicular diagonals are in the ratio of 2 to 1. What is the area of the rhombus, in square units?
Answer:
2880 square units
Step-by-step explanation:
Since the area of a rhombus, A = d₁ × d₂/2 where d₁ and d₂ are its diagonals. Given that d₁:d₂ = 2:1, d₁/d₂ = 2/1, so d₁ = 2d₂. Also, the length of side of the rhombus L = 60 units.
We find the length of the diagonal by Pythagoras' theorem since the diagonals are perpendicular to each other and bisect each other at their mid point.
The mid point of d₁ = d₁/2 and the midpoint of d₂ = d₂/2.
By Pythagoras' theorem,
L² = (d₁/2)² + (d₂/2)²
L² = d₁²/4 + d₂²/4
Now, d₁ = 2d₂
So, L² = (2d₂)²/4 + d₂²/4
L² = 4d₂²/4 + d₂²/4
L² = d₂² + d₂²/4
L² = 5d₂²/4
d₂² = 4L²/5
taking square root of both sides,
√d₂² = √(4L²/5)
d₂ = 2L/√5
Since L = 60 units, then
d₂ = 2L/√5
d₂ = 2(60)/√5
d₂ = 120/√5
rationalizing the denominator by multiplying the numerator and denominator by √5, we have
d₂ = 120/√5 × √5/√5
d₂ = 120√5/5
d₂ = 24√5 units
So, our area A = d₁ × d₂/2
Since d₁ = 2d₂, our area is
A = 2d₂ × d₂/2
A = d₂ × d₂
A = d₂²
substituting d₂ = 24√5, we have
A = d₂²
A = (24√5)²
A = (24)²(√5)²
A = 576 × 5
A = 2880 square units

Andrew is paid £250 a week. Each week, he shares his pay with his sister in the ratio 3 : 2 saves 12% of his share. How many weeks will it take Andrew to save £360?
Answer:
20 weeks
Step-by-step explanation:
The computation of The number of weeks it will take to save £360 is shown below:
Now $250 should be divided into a ratio of 3:2
He keeps = 150
ANd, he gives her = 100
As he saves 12% of his share
i.e.
= 12% of 150
= 18
Now the number of weeks would be
= 360 ÷ 18
= 20 weeks

2. A landscaper drew a scale drawing of a rectangular yard using the scale, , before beginning to work on the yard.(a) The landscaper plans to put a fence around the entire yard. How many meters of fencing does she need?
Complete question :
A landscaper drew a scale drawing of a rectangular yard using the scale, , before beginning to work on the yard.
(a) The landscaper plans to put a fence around the entire yard. How many meters of fencing does she need? Show your work.
(b) The landscaper plans to create a rectangular garden that is the size of the actual yard. What is the area of the garden?
Answer:
28cm ; 48cm²
Step-by-step explanation:
From the diagram :
Length = 8cm
Width = 6cm
Meters of fencing required :
Perimeter of rectangle :
P = 2(length + Width)
P = 2 (8cm + 6cm)
P= 2(14cm)
P = 28 cm
2.)
Area of rectangle :
Length * width
8cm * 6cm
= 48cm²
h(x) = x^2 + 2 - x
g(x) = 4x + 5
find (h - g) (x/3)
Answer:
x^2 - 15x - 27
---------------------- (Answer C)
9
Step-by-step explanation:
(h - g)(x) is the difference between funcions h and g. Subtract g(x) from h(x) as follows:
x^2 + 2 - x
-(4x + 5)
-------------------
x^2 - 5x - 3 = (h - g)(x)
To find (h - g)(x/3), substitute x/3 for x in x^2 - 5x - 3 = (h - g)(x), obtaining:
(x/3)^2 - 5(x/3) - 3
We must expand this and then combine like terms:
x^2/9 - (5/3)x - 3
The LCD of these three terms is 9. The first term stays as is. The second term becomes (15/9)x. The third term becomes 27/9.
Combining these three terms, all with denominator 9, we get:
x^2 - 15x - 27
----------------------
9
This matches Answer C.
Solve this inequality for x: - 3(x + 3) > 30
Answer:
x<-13
Step-by-step explanation:
−3(x+3)>30
Divide both sides by −3. Since −3 is negative, the inequality direction has changed.
x+3<30/-3
Divide 30 by −3 to get −10.
x+3<−10
Subtract 3 from both sides.
x<−10−3
Subtract 3 from −10 to get −13.
x<−13

Prove that the square of an odd number is always 1 more than a multiple of 4.
Input note: use 2n +1 as your odd number, and leave your answer in the form
4(...) +1
(4 marks)
Answer:
See explanation.
Step-by-step explanation:
If the odd number is 2n+1 note that n can be any number because any even number plus one will be odd. Let's start by squaring 2n+1 to get:
[tex]4n^2+4n+1[/tex]
Consider xy (x times y). xy is a multiple of both x and y because xy/x = y and xy/y = x. So it doesn't matter what n is it will be a multiple of 4. So now we know that 4n^2 and 4n are both multiples of 4. If we add them together, it will still be a multiple of 4. 2x + 4x = 6x and 6x is still divisible by x.
Now the plus 1 will always make it so it will be one more than a multiple of 4.

¿Me pueden ayudar con esta ecuación? 9 x + (x - 7) = (5 x + 4) - (8 - 3 x) Es que mi profe dice que es 3/2 pero me sale otra cosa... Gracias <3
Responder:
x = 3/2
Explicación paso a paso:
Dada la ecuación
9 x + (x - 7) = (5 x + 4) - (8 - 3 x)
Debemos encontrar el valor de x que satisface la ecuación

Answer and Step-by-step explanation:
A pair of segments that are perpendicular to each other are the line segments:
KI (the letter i) and MJ.
This is because we see that at the intersection T, there a right angle symbol, which means that those 4 angles at the intersection are 90 degrees. When a line meets another line, and it is perpendicular to that line, they form 90 degrees.
So, those line segments are perpendicular.

Kay's Dessert Shop bakes cookies. The ratio of chocolate chip to sugar cookies baked is always 5 to 2. If she bakes 210 cookies in one day, how many were sugar cookies? 50 points
Answer: 60
Step-by-step explanation:
Given
The ratio of chocolate chip to sugar cookies is 5:2
If she bakes 210 cookies in one day
Suppose she baked x amount of chocolate chips on that day
So, we can write
[tex]\Rightarrow x=\dfrac{2}{5+2}\times 210\\\\\Rightarrow x=\dfrac{2}{7}\times 210=60[/tex]
There were 60 sugar cookies on that day
