12(4x - 5) + 52 = 10 <em>|use distributive property</em>

(12)(4x) + (12)(-5) + 52 = 10

48x - 60 + 52 = 10

48x - 8 = 10 <em>|+8</em>

48x = 18 <em>|:48</em>

Chef Jess made a cake with an area of 93 1/2 inches if the width of the cake was 8 1/2 inches what was the length of the cake

dybincka [34]

Answer:

L= 11

Step-by-step explanation:

Formula to find the length when you know the area:

L = A/W

So the equation for this one is:

L = 93 1/2 ÷ 8 1/2

Simplify:

L = 11

To be sure of your answer you multiply the L x W = A

11 x 8 1/2 = 93 1/2

Hope this helped : D

Find the area of the circle to find the nearest whole number. Use 3.14 or 22/7 for ip

sertanlavr [38]

Answer:

You didn't provide the complete question as the radius or diameter of the circle isn't given. Please check the explanation below to see how to approach such questions.

Step-by-step explanation:

Area of a circle has a formula and it is given as:

Area = $\pi r^{2}$

where $\pi$ is a constant and has a value of 3.14 or 22/7,

r is the radius of the circle (i.e the line drawn from the center of the circle to any point on the circle).

radius, r = diameter/2.

Example 1: Find the area of a circle with radius 7meters (7m) and correct to the nearest whole number. Use 3.14 or 22/7 for pi.

Solution:

$Area = \pi r^{2} = \frac{22}{7} (7^{2})\\\\ Area = \frac{22}{7} (7)(7) = 22(7)\\\\ Area = 154squaremeters = 154m^{2}\\$

NB: The unit of area is always in square units. In our case square meters

Example 2: Find the area of a circle with diameter 7feet(7ft). Use 3.14 or 22/7 for pi.

Solution:

$Area = \pi r^{2}$

But we were given the diameter not the radius.

Remember that I earlier said that radius, r = diameter/2 = $\frac{7}{2}ft$

$Area = \frac{22}{7}(\frac{7}{2} )^{2} = \frac{22}{7} (\frac{7}{2} )(\frac{7}{2} )$

$Area = \frac{11(7)}{2} = \frac{77}{2} \\\\ Area = 36.5ft^{2}$

So, if you have questions that ask for area, ensure you have the radius and if the diameter is given instead of the radius, carry out the neccessary calculation i.e. Diameter/2 to obtain the radius and use the area formula.

The graph is showing the equation of circle x²+y²=4

<h3>What is a circle?</h3>

A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point.

The given graph in the question represents the equation of the circle cutting the points on the x-axis and y-axis at 4 which is the radius of the circle.

The equation will be as follows:-

x²+y²=4

Hence the graph is showing the equation of circle x²+y²=4
