Answer:

your perimeter will be 40cm

The 4 sides of a square are the same length. Find the length of a side by taking the square root of the area.

Side = sqrt(100) = 10 cm

Perimeter = side length x 4

Perimeter = 10 x 4 = 40 cm

Answer:

y  = 3

Step-by-step explanation:

P ( 1 , 3)    and  Q ( 3 , 3 )

The straight line is parallel to the x-axis since the two points have the same y.

The intercept with the y-axis is 3.

The slope-point equation for a line is:

y  = m*x + b             (1)

m is the slope and  b is the intercept with the y-axis

To calculate the slope

m =  (  y₂ -  y₁ ) /  ( x₂  -  x₁ )

m =  3 - 3 / 3 - 1          m   = 0 / 2      m  = 0

therefore, equatio (1) becomes

y  =  0*x + 3

y  = 3

Answer:   The height is 3  units.

Step-by-step explanation:

By using the give figure we can form right angle out of the whole figure  with a base of  4  and an hypotenuse of 5.

By using this information we can use the Pythagorean Formula to find the height

a^2 + b^2 =c^2     a= base, b = height and c will be the hypotenuse.

4^2 + b^2 = 5^2     Solve for B

16  + B^2 = 25  

-16               -16

    b^2 = 9    

    b = [tex]\sqrt{9}[/tex]  

  b  = 3

The height, h, of the triangular prism is 3 units.

Isosceles triangles are those triangles that have at least two sides of equal measure and two base angles are equal.

Given that, vertical cross-section of the triangular prism shown in the given figure is an isosceles triangle.

Here, equal sides of an isosceles triangle is 5 units and base of the isosceles triangle is 8 units.

By using Pythagoras theorem,

5²=h²+4²

25=h²+16

h²=9

h=3

Therefore, the height, h, of the triangular prism is 3 units.

Answer:

y = 12

Step-by-step explanation:

proportions can be solved by cross-multiplying

to work with smaller numbers, you can simplify [tex]\frac{14}{10}[/tex] to be [tex]\frac{7}{5}[/tex]

[tex]\frac{7}{5}[/tex] = [tex]\frac{y+9}{15}[/tex]

7(15) = 5(y + 9)

105 = 5y + 45

60 = 5y

Answer: x = 5

Step-by-step explanation:

Hey there! If you have any questions, feel free to let me know in the comments.

Step 1: Simplify  20 - 4x - 15 - 4x  to  5 - 8x.

5 - 8x = -6x - 45 + 8x

Step 2: Simplify -6x - 45 + 8x to 2x - 45.

5 - 8x = 2x-44

Step 3: Add 8x to both sides.

5 = 2x - 45 + 8x

Step 4: Simplify 2x - 45 + 8x to 10x - 45.

5 = 10x - 45

Step 5: Add 45 to both sides.

5 + 45 = 10x

Step 6: Simplify 5 + 45 to 50.

50 = 10x

Step 7: Divide both sides by 10.

50/10 = 10x/10

Step 8: Simplify 50/10 to 5.

step 1

20-4x-15-4x=-6x-45+8x  equation

step 2

20-4x-15-4x=-6x-45+8x  simplify for x

20+(-4x)+(-15)+(-4x)=(-6x)+(-45)+8x

step 3

(-4x+-4x)+(20+(-15)=(-6x+8x)+(-45)  add brackets to seperate the equations

step 4

-8x+5=2x+-45  combine the terms that are alike

step 5

-8x+5(-2x)=2x-45(-2x)  subtract -2x(the ones in the brackets)

Answer:

10 feet

Step-by-step explanation:

You use the pythagorean theorem to find the missing side of a right triangle.

side^2 + side^2 = hypotenuse ^2

6^2 + 8^2 = X^2

36 + 64 = 100

square root of 100 = 10

Answer:

18.852:50.272

Step-by-step explanation:

Step one:

given

The radii of two right circular cylinders are in the ratio 3 : 4

r1= 3

r2= 4

Their heights are in the ratio 1 : 2

h1= 1

h2= 2

Step two:

The expression for the curve surface area is

CSA= 2πrh

CAS1=  2πr1h1

CAS1=  2*3.142*3*1

CAS1=  18.852

CAS2=  2πr2h2

CAS2=  2*3.142*4*2

CAS1=  50.272

The ratio of their curved surface areas

=18.852:50.272

Answer:

The correct option is;

B

Step-by-step explanation:

The given system of inequalities are;

5·x - 4·y > 4...(1)

x + y < 2...(2)

Representing both inequalities as a function of "y", gives;

For, 5·x - 4·y > 4...(1), we have;

-4·y > 4 - 5·x

y < 4/(-4) - 5·x/(-4)

∴ y < 5·x/4 - 1

For x + y < 2...(2), we have;

y < 2 - x

Therefore, y is less than the values given by the equation of the straight line equalities, and the feasible region is given by the common region under both dashed lines representing both inequalities as shown in the attached diagram created using Microsoft Excel

The correct option is therefore, B.

Answer:

Answer:

(1,6)

Step-by-step explanation:

In order to reflect a point over a horizontal line, you need to count how many units it takes to reach that line (going vertically). Once you have that number, count that many units starting from that point on the line (again, going vertically), then that is your reflected point.

Counting from point Q to the line y = 2, it takes 4 units. So starting from that point on the line where I left off, I would count another 4 units, taking me to (1,6). The picture below explains it better visually.

Answer:

96 pizzas

Step-by-step explanation:

Allan can make 8 pizzas in 15 minutes at the pizza restaurant where he works.

We are told that;

If the number of pizzas varies directly with minutes,

P ∝ M

P = kM

Hence:

8 = 15k

k = 8/15

How many pizzas can Allan make in 3 hours?

Convert 3 hours to minutes

1 hour = 60 minutes

3 hours = x

x = 3 × 60

x = 180 minutes

Hence,

M = 180 minutes

k = 8/15

P = kM

P = 8/15 × 180

P = 96 pizzas

Therefore, Allan can make 96 pizzas in 3 hours

Answer:

lemon cookies = 70 calories

fudge cookies = 95 calories

Step-by-step explanation:

Lemon cookies = "x"

Fudge cookies = "y"

As per what is given;

3x + 2y = 400

2x + 3y = 425

Multiply the first equation by (-3), and the second by (2)

-9x - 6y = -1200

4x + 6y = 850

________________

-5x = - 350

Inverse operations;

-5x = -350

/-5      /-5

x = 70

Subsitute back in;

3x + 2y = 400

3(70) + 2y = 400

Simplify, inverse operations;

210 + 2y = 400

-210           -210

2y = 190

y = 95
