Find the surface area. Please help!! I need it quick

Answers

Answer 1

Answer:

This is a right trapezoidal prism.

To find the total surface area,

First we have to find the area of the 2 trapezoids.

Let us find now.

[tex]Area=2*\frac{1}{2} (a+b)*h[/tex]

[tex]Area=2*\frac{1}{2} (1.4+2.3)*1.9\\[/tex]

[tex]Area=3.7*1.9[/tex]

[tex]Area = 7.03m^{2}[/tex]

Now you have to find the areas of the 3 rectrangles.

Let us find now.

(4.8 × 2.1) + ( 4.8 × 2.3)+ ( 1.9 × 4.8)

10.08 m² + 11.04 m² + 9.12 m²

= 30.24 m²

Now let us find the total surface area of this solid.

7.03 m² + 30.24 m²

= 37.27 m²

If the height of a cone is 7.5 cm and the radius is 2 cm, find the approximate volume of the cone.

Answers

Volume: h • pi r^2

Volume: (7.5) • pi (2)^2

Volume: 94.247796

Just round to your teacher’s liking

Answer:

The volume of the cone is approximately 31.43 cm³

Step-by-step explanation:

We know that:

Volume of cone: πr²h/3h = 7.5r = 2

Work:

πr²h/3=> π x r² x h/3=> 22/7 x 2² x 7.5/3=> 22/7 x 4 x 2.5=> 22/7 x 10=> 220/7=> 31.43 (Rounded to nearest hundredth.)

Hence, the volume of the cone is approximately 31.43 cm³

ABC is a straight line.

The length AB is five times the length BC .

AC =90 cm.

Work out the length AB .

(3 marks)

Answers

Answer:

75 cm

Step-by-step explanation:

According to segment addition postulate we have:

AC = AB + BC

We are given:

AB = 5 BC

Then substitute values into the first equation:

AC = 5 BC + BC90 = 6 BCBC = 90/6 = 15 cm

Find the length of AB:

AB = 5*15 cm = 75 cm

What is the distance between −93 and 114 on a number line?

Answers

Answer:

207

Step-by-step explanation:

By counting the amount of numbers to get from -93 to 114, you count a total of 207. This means it takes 207 steps to get from -93 to 114.

When finding the distance between negative and positive numbers you can also add the numbers together to get the total distance between the numbers.

Answer:

y = (-1/2)x + 2

Step-by-step explanation:

The black line slopes down as we move from left to right, so we conclude that the slope is negative. From (0, 2) to (4, 0), y drops by 2 units (the rise) and x increases by 4 units (run).

Thus the slope is m = rise / run = -2/4, or m = -1/2.

The y-intercept is (0, 2), so the value of b in the equation y = mx + b is 2.

Thus the equation of this line is y = mx + b => y = (-1/2)x + 2

Answer:

y < 5

Step-by-step explanation:

Subtract 22 from both sides.

7y < 5y + 12 - 2

7y < 5y + 12 − 2

2 Simplify 5y + 12 - 25y + 12 − 2 to 5y + 105y + 10.

7y < 5y + 10

3 Subtract 5y5y from both sides.

7y - 5y < 10

4 Simplify 7y - 5y7y − 5y to 2y.

2y<10

Divide both sides by 22.

y < 10/2

Then Simplify 10/2 to 5

y < 5

knife is 3 times cost of spoon
9 spoons and 12 knifes is £82.80
what is 1 knife

Answers

Answer:

The cost of spoon is £1.84 and therefore the cost of one knife is £5.52.

Given :

A knife is 3 times the cost of the spoon. 9 spoons and 12 knives costs £82.80.

Solution :

This question is solve by creating a linear equation and linear equations are nothing but yet another subset of "equations". Linear calculations that requires more than one variable can be done with the help of linear equations. The standard form of a linear equation in one variable is ax + b = 0.

Now let x be the cost of spoon. Than the cost knife is 3x. It is given that 9 spoons and 12 knives costs £82.80.

[tex]9x + 12 x (3x) = 82.809x + 36x = 82.8045x = 82.80x = 1.84[/tex]

Therefore the cost of 1 knife = 5.52

Step-by-step explanation: [tex]1.84 x 3 = 5.52[/tex]

What is the area of this figure?

Answers

Given :-

A figure is given to us .

To Find :-

The area of the figure .

Solution :-

As we can see that the given figure is made up of a parallelogram and a ∆ . As we know that the opposite sides of a parallelogram are equal . So that the base of the ∆ would be 9cm . Now ,

[tex]\longrightarrow[/tex] Area = ar(||gm ) + ar(∆)

[tex]\longrightarrow[/tex] Area = (9*5 + 1/2*8*9)cm²

[tex]\longrightarrow[/tex] Area =( 45 + 45 ) cm²

[tex]\longrightarrow[/tex] Area = 90cm²

Hence the area of the given figure is 90cm² .
