The base of a square measures 7 cm, and its height measures 6 centimeters. How tall is your area?
Alexxandr [17]

Answer:

42cm^{2}

Step-by-step explanation:

In order to find the area of a square you take the base and multiply it by the height.

Base x Height = Area

In this case you have 7cm as the base and 6cm as the height.

All you have to do after that is multiply the two together.

Make sure that you remember to put the unit (cm) and make sure that it is cm^{2} because some teachers are uptight about that stuff.

Hope this helped!

Two friends went to a restaurant and ordered one plain pizza and two sodas. Their bill totaled $15.95. Later that day, five frie
Sliva [168]

Step-by-step explanation:

Given

One plain pizza and two sodas cost $15.95

Similarly, 3 plain pizzas and 5 sodas cost $45.90

Suppose the cost of single pizza and soda be x and y

In linear equation format, it can be written as

\Rightarrow x+2y=15.95\\\Rightarrow 3x+5y=45.90

Therefore, the above two equations represents the given situation.

2+6i/2-4i = a + bi What is the value of a? What is the value of b?
Talja [164]

\dfrac{2+6i}{2-4i}\\\\\\=\dfrac{2(1+3i)}{2(1-2i)}\\\\\\=\dfrac{1+3i}{1-2i}\\\\\\=\dfrac{(1+3i)(1+2i)}{(1-2i)(1+2i)}\\\\\\=\dfrac{1+2i+3i+6i^2}{1-(2i)^2}\\\\\\=\dfrac{1+5i-6}{1+4}~~~~;[i^2=-1]\\\\\\=\dfrac{5i-5}{5}\\\\\\=\dfrac{5(i-1)}5\\\\=i-1\\\\=-1+i\\\\\text{It is in a form of a +bi so,}~ a = -1~ \text{and}~ b = 1

2. You are creating a cone-shaped hat for a kid’s costume. You measure the circumference of the child’s head and find it to be 2
Monica [59]
Just draw a triangle(front view) and the slant/inclined sides of it are known to be 8 and you found out radius as 3.26. so mark the diameter by doubling radius.

so the material required would be a slice(like pizza slice) of a circle of radius= 8 and arc length = circumference given ,that is 20.5

now using this find the area of sector/slice. its the answer to the last bit.

now coming to next question, go to the kitchen and take any can and measure its dia and height by using a scale. and you might already know the formula to find the suface area of cylinder.
