Answer:

137 ft²

Step-by-step explanation:

The shop is rectangular in shape. The area of a rectangle is given by:

Area = length * width

Since the length of the shop = 20 ft and the width = 10 ft, therefore:

Area of the shop = length * width = 20 ft * 10 ft = 200 ft²

The part that would not be tiled is of triangular shape. The area of a triangle is given as:

Area = (1/2) * base * height

The base of the triangle = 18 ft, the height = 7 ft. Hence:

Area of non tiled part = (1/2) * base * height = (1/2) * 18 ft * 7 ft = 63 ft²

The total square feet of tile needed to complete the job = Area of shop - Area of non tiled part

The total square feet of tile needed to complete the job = 200 ft² - 63 ft² = 137 ft²

the first box and the last box

Answer:

18 pounds = 48 pizzas

18 pounds = 48 pizzas 22.5 pounds = 60 pizzas

18 pounds = 48 pizzas 22.5 pounds = 60 pizzas 27 pounds = 72 pizzas

Step-by-step explanation:

1) because they are ratios you multiply 18 and 8 (18 × 8 = 144) then you divide 144 by 3 (144÷3 =48)

2) now you do the same thing multiply 22.5 and 48 (22.5 × 48= 1,080) and divide 1,080 by 18 (1,080 ÷ 18= 60)

3) multiply 27 times 60 (27 × 60= 1,620) now divide 1,620 by 22.5 (1,620 ÷ 22.5= 72)

The table is:

Cheese   Number of Pizzas

3 pounds          8

18 pounds        48

22.5 pounds    60

27 pounds        72

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

3 pounds bag of cheese makes 8 pizzas.

This means,

3 pounds = 8 pizzas

1 pound = 8/3 pizzas

Now,

1 pound = 8/3 pizzas

Multiply 18 on both sides.

18 pounds = 18 x 8/3

18 pounds = 48 pizzas

1 pound = 8/3 pizzas

Multiply 22.5 on both sides.

22.5 pounds = 22.5 x 8/3

22.5 pounds = 60 pizzas

1 pound = 8/3 pizzas

Multiply 27 on both sides.

27 pounds = 27 x 8/3

27 pounds = 72 pizzas

Thus,

The number of Pizzas for 3 pounds is 8.

The number of Pizzas for 18 pounds is 48.

The number of Pizzas for 22.5 pounds is 60.

The number of Pizzas for 27 pounds is 71.

x = 118 degrees approximately

Step-by-step explanation:

Here, we want to get the measure of the angle marked x

We shall use the side facing it and apply the cosine rule

The side facing the angle measures 90

Thus, we have it that;

90^2 = 55^2 + 50^2 - 2(50)(55) cos X

2575 = - -5,500 cos X

X = cos^-1(-2575/5,500)

X = 118 degrees approximately

y=32.7

I am taking 7I+x to  mean 71+ x.

Answer:  y=1.837

Step-by-step explanation:

Step 1

Let y is inversely proportional to 7I+x be  mathematically be written as

y ∝ 1/7I+x

Introducing our proportionality of constant , K we have that

y ∝ 1/7I+x

y =K 1/7I+x

y= K/ 7I+xh

Step 2

so when x= 8, and y =2,  k becomes

y= K/ 7I+x

k=  y x (7I+x)

=2 x (71 + 8)

2x 79

=158

 when x= 15, y =?

y= K/ 7I+x

y= 158/  71 + 15

y=158/86

y=1.837

Answer:

47.5°

Step-by-step explanation:

(2x+10)°+75°= 180°------ sum of angles of a triangle

or, (2x+10°)=180°-75°

or, (2x+10°)=105°

or, 2x=105°-10°

or,2x=95°

or, x= 95÷2

therefore, x=47.5°

Answer:

x=21.25

Step-by-step explanation:

The lower two angles will be equal in an isosceles triangle and all angles in a triangle add up to 180 degrees so:

75+(2x+10)+(2x+10)=180

75+4x+20=180

4x=85

x=21.25

(both lower angles=52.5 degrees)

Answer:

The new function is g(x) = x² +1

Step-by-step explanation:

Explanation:-

Given that the function f(x) = x²

From graph ,

The parabola  y = x² is shifting to up with '1' units

                    y = x² +1

The new function is g(x) = x² +1

Verification:-

    y = x²+1

Put x=0 ⇒ y =1

The point (0,1) lies on the parabola y = x²+1

similarly put x =1 and y = 2

The Point (1,2) lies on the Parabola y = x²+1

∴ The new graph  y = x²+1

Step-by-step explanation:

Area of Shaded part

= 2 * Area of Quarter-circle - Area of Square

= 0.5π(8)² - 8²

= 32(π - 2)cm².

Perimeter of Shaded part

= 0.5 * 2π(8)

= 8πcm.

The perimeter of the shaded part is 8πcm and the area of the shaded part is 8πcm and 0.5π(8)² - 8² respectively

Radius, r = 8 cm

= 1/2πr

Perimeter of Shaded part = 1/2 * 2πr

= 1/2 × 2 × π × 8

Step-by-step explanation:

Answer:

No

Step-by-step explanation:

To have a triangle you have to add up the two shorter sides and it should be greater than or equal to the longest side.

12 + 14 = 26

26 is less than 27

Given :

Two equations :

-8x + 3y = -17  ....1)

3x - y = 7        ....2)

To Find :

The solution of the system.

Solution :

Multiplying equation 2) by 3 and adding with equation 1), we get :

(-8x + 3y) + 3(3x - y) = -17 + 21

x = 4

Putting above value of x equation 2) we get :

12 - y = 7

y = 5

Therefore, solution of system is ( 4,5 ).

Using the Pythagorean theorem:

6^2 = 5^2 + x^2

Simplify:

36 = 25 +x^2

Subtract 25 from both sides:

11 = x^2

Square root of both sides:

x = sqrt(11) (exact) or 3.316625 as a decimal

Answer:

J(0,2)

Step-by-step explanation:

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.

The new coordinate of the point j' will be (-8, 12).

A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.

It is the image of the point which is located in the opposite direction of a given point.

Point j (-8, -12) is reflected over the x-axis. Then the coordinate of the reflected point j' will be  

If the coordinate of a point is (x, y) and it is reflected across the x-axis. Then the coordinate of the reflected point will be (x, -y).

Then the new coordinate of the point j' will be (-8, 12).
