How can you find 100% of Carmen's earnings using
the ratio of her earnings to 10%? What is 100% of
Carmen's earnings?
Carmen's total earning will be 10x when 10% earning is assumed to be x.
What is proportion ?
A proportion is an equation based on the equality of two ratios.
Let x be the earning of Carmen's that is equals to 10% of total earning.
Then total earning that is 100% will be equals to the multiplication 10% and x both with 10 :
10%( total earning of Carmen's ) = x
100%( total earning of Carmen's ) = 10x
Therefore, Carmen's total earning will be 10x when 10% earning is assumed to be x.

Oscar is building a fence and purchases three boards that each measure
2.91 meters long. How many meters of fence board did Oscar purchase?
Oscar bought 8.73 meters of fence board to build the fence.
The metric system and the International Systems of Units both use the metre (m), also spelt as meter, as the basic unit of length (SI). In the British Imperial and American Customary systems, it is equivalent to roughly 39.37 inches.
A fence is a building used to enclose a space, usually outdoors. It is often made of posts joined by boards, wire, rails, or nets.
Oscar purchases three boards that measure 2.91 meters long each to build a fence.
Let say the length of one board be x = 2.91 meters.
Then the total length of fence board Oscar purchases is:
= 3x = 3 × 2.91 meters = 8.73 meters
Hence Oscar purchased 8.73 meters of fence board.

in a class of 25 students, 15 of them have a cat, 16 of them have a dog and 3 of them have neither
Answer: The probability that a student chosen at random has a cat and a dog is; P(cat and dog) = 9/25.
Step-by-step explanation:
According to the question, the total number of students is; 25.
15 of them have a cat
16 of them have a dog
while, 3 of them have neither
The information above are drawn in a Venn diagram in the attached image.
where, x = number if students who own a cat and a dog.
Consequently, the total number of students who own a cat, a dog, both or neither is as follows;
15-x + x + 16-x + 3 = 25.
-x = 25 - 34
In essence, x = 9
Therefore, the number of students who own a cat and a dog is 9.
The probability that a student chosen at random has a cat and a dog is therefore;
P(cat and dog) = 9/25.

A car rental agency rent 190 cars per day at a rate of $40 per day for each one dollar increase in rate five fewer cars are rented at what rate should the cars be rented to produce the maximum income?
The rate that the cars should be rented to produce the maximum income is: 41 Dollars/Day, Maximum income 7615.
Rate and maximum incomeLet y represent the income
Let x represent the increase in rental price after increasing the rental price is 40+x.
Let 190-5x represent the number of cars rental after a rental price increase
Income expression
y=(190-5x) (40+x)
Let differentiate y with respect to x and set y' =0 to determine the maximum income
Hence,
y=(190-5x) (40+x)
=(190) (40) + 190 (x) -5x(40) -5x-(x)
=7600 +190x-200x-5x²
y= -5x² +10x+7600
Differentiate with respect to x
y'=d/dx ( -5x² +10x+7600)
y'=-10x+10x
set y'=0
-10x+10=0
10x=10
x=10/10
x=1
Maximum Rate =40+x
=40+1
=41 Dollars/Day
Maximum Income is
y= ( -5x² +10x+7600)
=(−5(1)²+10(1)+7600)
=−5(1)+10+7600
=5+10+7600
=7615
Therefore the rate that the cars should be rented to produce the maximum income is: 41 Dollars/Day, Maximum income 7615.

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

Given the distance covered and the time elapsed, Ryashkina's average walking rate is approximately 3.97 meters per second.
What was Ryashkina's average walking rate?Rate or speed is expressed as distance walked or traveled per unit time.
R = s/t
Given the data in the question;
Distance covered s = 10,000mTime elapsed t = 41 minutes 56.23 secondsRate r = ?First convert 41 minutes to seconds.
⇒ 41min = ( 41 × 60 )s = 2460sec
Now, Elapsed time t = 2460s + 56.23s = 2516.23 second
Next, we determine the rate.
R = s / t
R = 10000m / 2516.23 s
R = 3.97m/s
Given the distance covered and the time elapsed, Ryashkina's average walking rate is approximately 3.97 meters per second.

One of the legs of a right triangle measures 2 cm and its hypotenuse measures 4 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answer: 3.5
Step-by-step explanation:
To find the length of the missing leg, we need to use the Pythagorean Theorem (a^2 + b^2 = c^2 where c is the hypotenuse)
1) Plug in numbers
2^2 + b^2 = 4^2
2) Square
4 + b^2 = 16
3) Flip Equation and Subtract
16 - 4 = b^2
16 - 4 = 12
4) Square Root of 12
The square root of 12 is ~3.46, so you need to round to the nearest tenth, which is 3.5

The simplified value of the given expression is -11 - 2x.
BODMAS stands for Brackets of Division, Multiplication, Addition and Subtraction.
Here, we are given an expression as follows-
(3 * -8) + (2x+5) - (4x-8)
According to the rules of BODMAS, brackets must be solved first. Hence, we simplify the terms in brackets first as given below-
(-24) + (2x + 5) - (4x - 8)
Opening up the brackets we get-
-24 + 2x + 5 - 4x + 8
= -24 + 5 + 8 + 2x - 4x

What is −10 + |−4| − |−12|?
Answer:
-18
Step-by-step explanation:
-10 + |-4| - |-12| Since there are the | |, then any negative number inside would become a positive as it will become its absolute value, which for -4, would be 4, because it is 4 spots away from the 0 on a number line and vice versa.
-10 + 4 - 12 Answering from left to right,
-10 + 4, if you would rather make it so they are both equal, you change the + to the opposite which would be - and change the 4 back to a negative because that is what it would be if you changed the equation to be subtraction instead to be easier as they would both be negatives now, so you would subtract -10 - -4 and get -6.
-6 - 12. Again, switch the - to the opposite, which is +, and then make 12 the opposite that it was before so they both share the same symbol, making it
-6 + -12, which would be -18.
