Answer:

172 m^2.

So you already have it on the correct answer.

Step-by-step explanation:

For you to find the surface area, you need to find out the areas of all the different colored sections.

There are 6 sections.

2 green, 2 purple, and 2 red.

Green section: (length x width) 7 x 8 = 56

Purple section: (length x width) 2 x 8 = 16

Red section: ( length x width) 7 x 2 = 14

Total: 56 + 16 +56 + 16 + 14 + 14 = 172 cm².

Answer:

a) The best deal was in Japan

b) The difference is £38

Step-by-step explanation:

First, find out the cost in pounds for both of the purchases.

Japan:

          39856 / 188 = 212.

          the Japanese phone cost £212.

Spain:

          352.50 / 1.41 = 250.

          the Spanish phone cost £250.

Then, subtract the costs to find the difference:

          250 - 212 = 38

The Identical phone in Japan is €28163.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Price of the phone in Spain = €352.50

Price of the phone in Japan = ¥39856

Now,

€1 = ¥141.52

Multiply 39856/141.52 on both sides.

39856/141.52 x 1€ = 39856/141.52 x ¥141.52

€28163 = ¥141.52

Thus,

The cost of a phone in Japan is €28163.

Answer:

y = 1/4x - 3.

Step-by-step explanation:

We see that the line passes through the points (4, -2) and (0, -3) so the slope is (-3 - (-2) / (0-4)

= -1 / -4

= 1/4 = the slope of the line.

The slope-intercept form of a straight line is y = mx + b where m = slope and b = y-intercept. Here the y-intercept is at (0, -3) so b = -3.

So the equation of the line is y = 1/4x - 3.

Answer:

Option B.

Step-by-step explanation:

The given vertices of triangle ABC are (-1, -1), (-1, -5) and (0.5, -5).

We need to find the coordinates of triangle when it is translated two units left.

So, the rule of translation is

[tex](x,y)\rightarrow (x-2,y)[/tex]

Using this rule, we get

[tex]A(-1,-1)\rightarrow A'(-1-2,-1)=A'(-3,-1)[/tex]

[tex]B(-1,-5)\rightarrow B'(-1-2,-5)=B'(-3,-5)[/tex]

[tex]C(0.5,-5)\rightarrow C'(0.5-2,-5)=C'(-1.5,-5)[/tex]

The vertices of triangle A'B'C' are A'(-3,-1), B'(-3,-5) and C'(-1.5,-5).

Therefore, the correct option is B.

Answer:

the answer is B

Step-by-step explanation:

Answer:

Option D

Step-by-step explanation:

Hope this helps! :)

The coordinates of the preimage will be at A(-2.5, 5.5), B(-2.5, 2.5) and C (-6.5, 2.5)

Translation is a transformation technique for changing the size and position of an object on the x-y plane.

From the given diagram, the coordinate A'B'C' is given as:

A' = (-1, 2)

B' = (-1, -1)

C' = (-5, -1)

If the triangle ABC was translated according to the rule (x, y) = (x + 1.5, y-3.5) to create the image A'B'C'

A (x + 1.5, y-3.5) = (-1, 2)

x + 1.5 = -1

x = -2.5

y - 3.5 = 2

y = 5.5

Hence A = (-2.5, 5.5)

B = (x + 1.5, y-3.5) = (-1, -1)

x + 1.5 = -1

x = -2.5

y - 3.5 = -1

y = 2.5

Hence B = (-2.5, 2.5)

C (x + 1.5, y-3.5) = (-5, -1)

x + 1.5 = -5

x = -6.5

y - 3.5 = -1

y = 2.5

Hence C = (-6.5, 2.5)

Hence the graph that shows the pre image ABC is attached below

Answer: 201 square feet

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a cylinder: π x radius² x height (in our case the length of the pipe)

Since:

Diameter = radius x 2

In our case D =4

4 = 2radius

Radius= 4/2 = 2 ft

Now that we have the radius, we can use the volume formula replacing with the values given:

V = 3.14x 2² x 16 = 3.14 x 4 x16 =200.96 = 201 square feet

Answer:

Step-by-step explanation:

Assuming you want to factor, then you would use the factor by grouping method

x^2+4x + xy+4y

(x^2+4x) + (xy+4y)

x(x+4) + y(x+4)

(x+y)(x+4)

Therefore, x^2+4x + xy+4y factors to (x+y)(x+4)

Answer:

The radius is 14 with a circumference of 28

The radius of the circle with circumference 28π is given by r = 14 inches

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The circumference of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle.

The equation of circle is ( x - h )² + ( y - k )² = r²

For a unit circle , the radius r = 1

x² + y² = r² be equation (1)

Now , for a unit circle , the terminal side of angle θ is ( cos θ , sin θ )

Given data ,

Let the radius of the circle be represented as r

Now , the equation will be

The circumference of the circle C = 28π inches

And , circumference of circle = 2πr

On simplifying , we get

2πr = 28π

Divide by π on both sides , we get

2r = 28

Divide by 2 on both sides , we get

r = 14 inches

Hence , the radius of the circle is 14 inches

John's speed is 6.67 miles per hour. Therefore, it would take him approximately 0.15 hours or 9 minutes to run 1 mile at the same pace.

The subject of this problem is rate. We can calculate John's speed by dividing the distance he covers by the time it takes. In this case, John ran 5 miles in 3/4 of an hour. So, his speed is 5 miles divided by 3/4 hour, which equates to 6.67 miles per hour. This means he runs 6.67 miles in 1 hour.

Given that speed is constant, if John wants to run only 1 mile, we simply divide this distance by his speed. So, 1 mile divided by 6.67 miles per hour gives 0.15 hours, or approximately 9 minutes. So, it would take John about 0.15 hours or 9 minutes to run 1 mile at the same pace.
