Answer:

50.4 cookies (50 cookies)

Step-by-step explanation:

Make 42% into a decimal = 0.42

0.42x120=50.4

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.

Answer:

y - 7 =  [tex]-\frac{1}{4}[/tex] (x - 4)

Step-by-step explanation:

Find Slope: m = [tex]\frac{y_{2-}y_{1} }{x_{2-}x_{1} }[/tex]

m = [tex]\frac{6-(7)}{8-(4)}[/tex]

m = [tex]\frac{-1}{4}[/tex]

Point Slope Form: y - [tex]y_{1}[/tex] = m ( x - [tex]x_{1}[/tex] )

y - 7 = [tex]-\frac{1}{4}[/tex] (x - 4)

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.

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.

1 × 1 ÷ 2 = 1/2 yd^2 or 0.5 y^2

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.

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

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

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

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.
