The computation shows that Michael will take 22.5 hours to paint a similar sized house working
How to compute the value?Based on the information given, the appropriate equation to use will be:
= 1/15 + 1/18 + 1/Michael = 1/6
Add the two fractions on the left
11/90 + 1/Michael = 1/6
1/Michael = 1/6 - 11/90
Take the reciprocal
Michael = 45/2
Michael= 22.5
Michael will take 22.5 hours.

Find the circumference and area of circle X if each unit on the graph measures 1 centimeter. Round answers to the
nearest tenth, if necessary.
The circumference and area of the circle are 13cm and 13cm^2 respectively
How to determine the valuesThe formula for circumference of a circle is expressed as:
Circumference = 2πr
From the graph shown, we have the radius of the circle as 2 cm
Substitute the value into the formula
Circumference = 2 × 3. 142 × 2
Multiply through
Circumference = 12. 568
Circumference = 13cm
The formula for area of a circle is expressed as:
Area = πr^2
Substitute the value into the formula
Area = 3. 142 × (2)^2
Area = 3. 142 × 4
Area = 12. 568
Area = 13cm^2
Thus, the circumference and area of the circle are 13cm and 13cm^2 respectively.

Anna is analyzing her greeting card business's profits. She wants
more than 40% of the price pof her greeting cards to be profit.
If crepresents Anna's cost to make a greeting card, which inequality
represents the desired relationship between price and cost?
The relationship between the price and cost is p > c.
The cost of manufacturing a product has a direct bearing on its price and the revenue generated by each sale. The cost of a product or service is determined by the customer's willingness to pay. Profit is the sum of the price paid less the costs incurred.
The price of Anna's greeting cards is p.
The cost of making a single greeting card is c.
Anna wants the profit to be 40% of the price of her greeting cards.
Profit = 40% of p
Profit = 40% × p = 0.4p
Now, we know
Price = Profit + Cost
p = 0.4p + c

A traffic cone with a height of 20 in. is ideal for traffic control. Find the lateral area of a cone with a height of 20 in. and a diameter of 12 in. Round the answer to the nearest whole number.
The lateral area of the cone is 394 square inches
How to determine the lateral areaThe formula for lateral area of a cone is expressed as;
Lateral area = πr √h² + r²
Given that;
height = 20 inDiameter = 12 in, radius = 12/ 2 = 6 inSubstitute the values into the formula
Lateral area = 3. 142(6) √20² + 6²
Lateral area = 18. 85 √436

If Samuel cuts [tex]\frac{4}{7}[/tex] inches discs of metal, then he can make 7 discs from a metal post that measures [tex]\frac{1}{3}[/tex] foot in length
Given,
The total length of metal post= [tex]\frac{1}{3}[/tex] foot
Convert foot to inches
1 foot = 12 inches
[tex]\frac{1}{3}[/tex] foot= 4 inches
The length of each disc of metal = [tex]\frac{4}{7}[/tex] inches
Number of metal post that he can cut = Total length of metal post / The length of each disc of metal
[tex]=\frac{4}{\frac{4}{7} } \\=4(\frac{7}{4})\\ =7[/tex]

A. The probability of his character casting a spell will be 1/6.
B. The odds against choosing a green block is 2/9.
How to calculate the probability?A. It should be noted that probability has to do with the chance of a particular thing happening.
In this case, the odds in favor of his character casting a spell are 1/6, therefore the probability of his character casting a spell is 1/6.
B. When a child has a box full of colored building blocks and he chooses one block without looking, the probability of choosing a green block is 7/9, therefore, the odds against choosing a green block will be:
= 1 - P(green block)
