the figure shown is made up of a square and a triangle. Express the area of the figure in terms of y.
Answers
2. The area of the square (A1) is:
A1=(y)(y)
A1=y²
3. The area of the triangle (A2) is:
A2=(y)(4)/2
4. When you simplify it, you obtain:
A2=2y
5. Finally, you obtain the area of the figure (A) when you sum the area of the square and the area of the triangle:
A=A1+A2
A=y²+2y

if the legs of a right triangle are 8 and 10, find the length of the hypotenuse
Answers
You need to use the Pythagorean theorem.
a² + b² = c²
8² + 10² = c²
64 + 100 = c²
164 = c²
c = √164
c = 2√41
Decimal is 12.8
Thus, the length of the hypotenuse is 12
Let me know if you have any misunderstanding about the answer!
As always, I am here to help!
We can use Pythagoras' Theorem to solve this problem. The Pythagorean Theorem:
a² + b² = c², where c is the hypotenuse.
Your two legs measure 8 and 10; substitute them into the theorem:
a² + b² = c²
8² + 10² = c²
64 + 100 = c²
164 = c²
12.81 ≈ c
Answer:
The length of the hypotenuse is approximately 12.81 units.
Find the probability that when a couple has three children, at least one of them is a girl. (Assume that boys and girls are equally likely.)
Answers
1. Probability=1-[probability_all_boys].
for [probability_all_boys]=1/[all_possible_combinations];
for [all_combinations]=2³=8. It means that
Probability=1-(1/8)=7/8=0.875.
2. Probability=[needed_cases]\[all_possible_cases];
all possible combinations are:
bbb;ggg;bgg;bgb;bbg;gbg;gbb;ggb; - (where 'g' - girl, 'b' - boy) total 8.
needed cases: ggg;bgg;bgb;bbg;gbg;gbb;ggb, - total 7.
Probability=7/8=0.875
Final answer:
The probability of having at least one girl when a couple has three children can be found by calculating the probability of having all boys and subtracting it from 1.
Explanation:
Probability that at least one child is a girl:
Find the probability of having all boys: (1/2)³ = 1/8
Subtract this from 1 to get the probability of having at least one girl: 1 - 1/8 = 7/8
Which of the following is not a way to represent the solution of the inequality 2(x − 2) less than or equal to 2?
A number line with a closed circle on 3 and shading to the right
A number line with a closed circle on 3 and shading to the left
3 greater than or equal to x
x less than or equal to 3
Answers
Answer:
The correct option is 1.
Step-by-step explanation:
The given inequality is
[tex]2(x-2)\leq 2[/tex]
Divide both the sides by 2.
[tex]\frac{2(x-2)}{2}\leq \frac{2}{2}[/tex]
[tex](x-2)\leq 1[/tex]
Add 2 on both the sides.
[tex]x-2+2\leq 1+2[/tex]
[tex]x\leq 3[/tex]
The value of x is than or equal to 3. In other words 3 greater than or equal to x.
Since the sign of inequality is ≤, therefore a number line with a closed circle on 3 and shading to the left represent the above inequality.
Only the statement "A number line with a closed circle on 3 and shading to the right" is not is not a way to represent the solution of the given inequality.
Therefore the correct option is 1.

If John's car gets an average of 18 mpg and he fills his tank with 26.7 gallons of gas, how far can John travel on a tank of gas?
Answers
multiply 18 by 26.7 to get that answer
Answer:
480.6 miles.
Step-by-step explanation:
We have been given that John's car gets an average of 18 mpg. John fills his tank with 26.7 gallons of gas.
To find the distance traveled by John's car, we will multiply the distance covered per gallon by number of gallons in the tank.
[tex]\text{Total distance traveled by John's car}=\frac{18\text{ miles}}{\text{gallon}}\times \text{26.7 gallons}[/tex]
[tex]\text{Total distance traveled by John's car}=18\text{ miles}\times 26.7[/tex]
[tex]\text{Total distance traveled by John's car}=480.6\text{ miles}[/tex]
Therefore, John can travel 480.6 miles on a tank of gas.
What is the constant of proportionality in the equation 2y=6x
Answers
The constant of proportionality in the equation 2y = 6x is [tex]\( \frac{1}{3} \)[/tex].
In the equation (2y = 6x), the constant of proportionality represents the relationship between x and y. To isolate it, divide both sides of the equation by (6x):
[tex]\[\frac{2y}{6x} = \frac{6x}{6x}\][/tex]
This simplifies to:
[tex]\[\frac{1}{3} = \frac{y}{x}\][/tex]
So, the constant of proportionality is [tex]\(1/3\)[/tex], indicating that for every unit increase in x, y increases by [tex]\(1/3\)[/tex].

beth owes 17,000 on her car loan. The interest rate on her loan is 4.25% She will be paying this loan off for 4 years. How much will she pay altogether?
Answers
To find the total payment Beth will make on her car loan, calculate the total cost using the loan formula. Beth will pay a total of $19,890 in total.
Explanation:Beth owes $17,000 on her car loan with a 4.25% interest rate, to be paid off over 4 years. To calculate the total amount she will pay, you use the formula for calculating the total cost of a loan: Total Payment = Principal + (Principal x Interest Rate x Time).
Principal = $17,000Interest Rate = 4.25% = 0.0425Time = 4 years.Plugging in the values:
Total Payment = $17,000 + ($17,000 x 0.0425 x 4)
Beth will pay a total of $17,000 + ($17,000 x 0.0425 x 4) = $17,000 + $2890 = $19,890 altogether.

the sum of the real numbers x and y is 15. their difference is 3. what is the value of xy?
Answers
x-y=3
the easiest way is the find out x and y first:
add up the two equations: 2x=18, x=9
plug x=9 in either equation, you get y=6
so xy=6*9=54
Another way to do it:
(x+y)²=15²=225 =>x²+2xy+y²=225
(x-y)²=3²=9 =>x²-2xy+y²=9
subtract one equation from the other: 4xy=225-9=216, xy=54
The value of xy is such that the sum of the real numbers x and y is 15 and their difference is 3 is 54.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
Given that sum of the x and y is 15
So,
x + y = 15
And difference
x - y = 3
By adding both equations,
2x = 18
x = 9 and y = 6
So their product 9 × 6 = 54.
Hence "The value of xy is such that the sum of the real numbers x and y is 15 and their difference is 3 is 54".

Samantha works at a nursery where she pots plants. It takes her 1 1/2 hours to pot 12 plants. How many plants can Samantha pot in 1 hour? (Please give me the equation you used.)
Please help fast!
Answers
You can use cross products to solve for x. Please see the attached picture for the steps. The answer is 8 plants.
Final answer:
Samantha can pot 8 plants in 1 hour.
Explanation:
To find out how many plants Samantha can pot in 1 hour, we need to determine how many plants she can pot in 1 1/2 hours and then convert that to 1 hour.
If Samantha can pot 12 plants in 1 1/2 hours, we can set up a proportion to find out how many plants she can pot in 1 hour:
12 plants / 1.5 hours = x plants / 1 hour
To solve for x, we can cross multiply:
12 * 1 = 1.5 * x
12 = 1.5x
To isolate x, divide both sides of the equation by 1.5:
x = 12 / 1.5
Simplifying the equation, we get:
x = 8
Therefore, Samantha can pot 8 plants in 1 hour.
