Answer:

Javier estimates the square root of 18 in the following way: √18=2√9=2*3=6 Explain why her reasoning is incorrect. Without using a calculator, the square root of 18 will be between what two values (remember to look for perfect squares/perfect square roots)? Show your reasoning. You do not need to find the decimal equivalent of the root.

Answer:

Solution given:

Answer:

x<15

Step-by-step explanation:

39in³ is a required volume.

Solution given:

for upper one

length[l]=8in

breadth[b] =3in

height[h]=1in

now

volume [V1]=l×b×h=8×3×1=24in³

again for lower one:

length[l]=6-1=5in

breadth[b] =3in

height[h]=1in

volume [V2]=l×b×h=5×3×1=15in³

Again

total volume =V1+V2=24in³+15in³=39in³

Answer:

the answer is 64

Step-by-step explanation:

becasue 4 time 4 is 16 and 16 times 4 is 64. You have to multiply 4 against itself 3 times.

Answer:

64

Step-by-step explanation:

4³ = 4 · 4 · 4 = 64

Answer:

For width W and length L, we have:

W = L = √(75ft^2) = 8.66ft

Step-by-step explanation:

For a rectangle of length L and width W, the area is:

A = L*W

and the perimeter is:

P = 2*L + 2*W

First, we know that the area of our rectangle is:

A = 75ft^2 = L*W

And we want to minimize the perimeter of our rectangle, then we need to minimize:

P = 2*L + 2*W

From the equation:

75ft^2 = L*W

We can isolate one of the variables, let's isolate L

L = (75ft^2)/W

We could replace this in the perimeter equation:

P(W) = 2*( (75ft^2)/W) + 2*W

P(W) = (150 ft^2)/W + 2*W

To find the minimum of the perimeter we need to look at the zero of the first derivative of P(W).

P'(W) = dP(W)/dW = -(150ft^2)/W^2 + 2

Now we need to find the value of W such that:

P'(W) = 0

0 =  -(150ft^2)/W^2 + 2

(150 ft^2)/W^2 = 2

(150ft^2) = 2*W^2

(150ft^2)/2 = W^2

75 ft^2 = W^2

√(75ft^2) = W = 8.66ft

And remember that:

L =  (75ft^2)/W

replacing with W = √(75ft^2)

L =  (75ft^2)/√(75ft^2) = √(75ft^2)

Then:

W = L = √(75ft^2) = 8.66ft

Answer:

x=26

Step-by-step explanation:

the angle is a right angle so

90-37= 53

53-1=51

52/2= 26 thats x?

if you dont understand i can still describe more

Answer:

i can't see it was blur

i can't answer can you pic it again

Answer: 200 in squared

Step-by-step explanation:

Each of the triangles in this picture are the same. You can tell because it's a square, and because of the dotted line.

Take the white triangle and substitute it for one of the black ones. Now, you have this.

Now, just do 10 * 20

= 200

Answer:

Step-by-step explanation:

2 in/16mi = 19 in/x mi

152 mi

Answer:

16 miles = x miles

(1/2) inch 2 3/4 inches

x = (11/4) * 16 = (11/4) * 2 * 16 = 88 miles

(1/2)

Step-by-step explanation:

As was the case in your previous question, this problem involves setting two ratios equal to each other. We call such an equation a proportion.

Answer:

14 inches

Step-by-step explanation:

She measures along the outer edge of the crust from one piece and finds it to be 5.5 inches.

We need to find the diameter of the pizza. A pizza is divided into 8 equal parts.

The circumference of one part = [tex]\dfrac{2\pi r}{8}=\dfrac{\pi r}{4}[/tex]

So,

[tex]\dfrac{\pi r}{4}=5.5\\\\2r=D=14\ inch[/tex]

So, the diameter of the pizza is 14 inches.

Answer:

1. The right triangles pass the AA similarity congruence theorem.

2. s/q

Step-by-step explanation:

They are similar since they pass the AA( Angle-Angle) similarity theorem.

Similar triangles have corresponding proportional sides so side z corresponds with side s and side x corresponds with q so we would represent that as

s/q

Answer:

Length: 10

Surface Area: 20

Step-by-step explanation:

Length:

2*12=24

240/24=10

Surface Area:

2*10=20

Answer:

1) B. similar

2) D. (4, 2)

Step-by-step explanation:

1)

When a figure is dilated, the shapes will be similar. Reflected is another transformation so that's wrong. Same size and congruent is wrong since that would have to make the dilated size equal which can't since it's contradicting.

2)

B: (4, -2)

Reflection across the x-axis:

(x, y) → (x, -y)

(4, -2) → (x, -y)

(4, 2)

Answer:

the numbers are 4,8,16,64 and 4096 using laws of indices

Answer:80017

Step-by-step explanation:

80017

Answer:

Step-by-step explanation:

You would first have to plug in for x, (which is already given). After plugging in for x, you would need to solve the equation to get y.

Once you have both x and y, you will have your (x,y)

For example: (given x value = -5)

[tex]f(x) = -|x - 5| -4\\f(-5) = -|(-5) - 5| - 4\\f(-5) = -|-10| - 4\\f(-5) = -10 - 4\\f(-5) = -14\\f(-5) = y = -14\\\\[/tex]

so:

x = -5

y = -14

( -5, -14)

Answer:

$12,960.00

Step-by-step explanation:

Use the formula A = P (1+rt)

A = (12000)(1+(0.04x2))

A = $12,960.00

Answer:

if the initial amount is 1200 then the answer is 1296

if the initial amount is 12000 then the answer is 12960

Answer:

3.60 dollars

Step-by-step explanation:

0.20 times 18 equals 3.60

as given in the diagram this is equalatral triangle where all the side and angle are same

the sum of the three angle in a triangle is always 180 degrees

as in this triangle all of the angles are the same its

[tex]5x+5x+5x= 180\\15x=180\\x= 12[/tex]
