a) If side a measures 90 feet and side b measures 120 feet, how many feet of flowers will be planted along side c, the hypotenuse of the triangle? Show your work and explain your reasoning.
(image below)
Answer:
90 squared is 8,100, and 120 squared is 14,400. So to figure out what c is you do 90^2 + 120^2 = Square Root of 22,500 which is 150.
So c = 150
Step-by-step explanation:
So C=150
hope this helps :D
By using the Pythagorean theorem, we will see that side C measures 150ft.
How to get the length of side C?
We can see that side C is the hypotenuse of a right triangle. We know both catheti of said triangle, then we can use the Pythagorean theorem.
It says that the sum of the squares of the cathetus is equal to the square of the hypotenuse. Then we have:
A^2 + B^2 = C^2
We know that:
A = 90ft
B = 120ft
Replacing that we get:
√((90ft)^2 + (120ft)^2) = C = 150ft
Then we conclude that side C measures 150ft.

A new laptop computer costs $800. The sales tax on the computer is $48. What is the PERCENT of the sales tax?
Answer:
6% sales tax
Step-by-step explanation:
48 / 800 = x / 100
What did you do to turn 800 into 100? Divide by 8.
Since we divided the denominator by 8, we also divide the numerator by 8.
48 / 8 = 6
6% sales tax
Final answer:
The percent of the sales tax on an $800 laptop computer with a $48 sales tax is 6%. This is found by dividing the sales tax by the cost of the computer and then multiplying by 100.
Explanation:
To calculate the percent of the sales tax for the laptop computer, you need to follow these steps:
Convert the sales tax amount to a decimal by dividing the sales tax by the cost of the item before tax.
For example: $48 (sales tax) ÷ $800 (cost of the laptop) = 0.06.
Then, convert the decimal to a percentage by multiplying it by 100.
Continuing the example: 0.06 × 100 = 6%.
Therefore, the sales tax rate for the laptop computer is 6%.

Step-by-step explanation:
First, let's find the price for a ticket with the markup.
Normally, you pay for 100% of the ticket price, but now you also have to pay an extra 20% of the ticket price.
100%+20%=120%
So, you are basically paying for 120% of the normal ticket price, $16
Multiply 120% and $16
120%*16
Convert 120% to a decimal by dividing by 100, or moving the decimal place 2 spots to the left
120%/100=1.20
120.0-->12.0-->1.20
1.20*16=19.2
Now, each adult ticket costs $19.20
Next, find how much 5 tickets will cost.
Multiply 5 and $19.20
5*19.20=96
5 adults will pay $96 with the ticket markup

Answer:
See below.
Step-by-step explanation:
ABC is an isosceles triangle with BA = BC.
That makes angles A and C congruent.
ABD is an isosceles triangle with AB = AD.
That makes angles ABD and ADB congruent.
Since m<ABD = 72 deg, then m<ADB = 72 deg.
Angles ADB and CDB are a linear pair which makes them supplementary.
m<ADB + m<BDC = 180 deg
72 deg + m<BDC = 180 deg
m<CDB = 108 deg
In triangle ABD, the sum of the measures of the angles is 180 deg.
m<A + m<ADB + m<ABD = 180 deg
m<A + 72 deg + 72 deg = 180 deg
m<A = 36 deg
m<C = 36 deg
In triangle BCD, the sum of the measures of the angles is 180 deg.
m<CBD + m<C + m<BDC = 180 deg
m<CBD + 36 deg + 108 deg = 180 deg
m<CBD = 36 deg
In triangle CBD, angles C and CBD measure 36 deg making them congruent.
Opposite sides DB and DC are congruent making triangle BCD isosceles.

[tex]h^2=324[/tex]
[tex]\sqrt{h^2}=\sqrt{324}[/tex]
[tex]h=18[/tex]
[tex]\text{Area of base triangle}=\frac{1}{2}\times24\times 18[/tex]
[tex]\text{Area of base triangle}=12\times 18[/tex]
[tex]\text{Area of base triangle}=216[/tex]
[tex]\text{Volume of triangular prism}=\frac{1}{3}b\cdot h[/tex]

Simplify the expression. −5x + 8y + 2x − 3y
Final answer:
To simplify the expression −5x + 8y + 2x − 3y, combine like terms, resulting in −3x + 5y.
Explanation:
To simplify the expression −5x + 8y + 2x − 3y, you want to combine like terms. The like terms are those with the same variable raised to the same power. In this expression, −5x and 2x are like terms, as are 8y and −3y.
Combine −5x and 2x: (−5 + 2)x = −3x
Combine 8y and −3y: (8 − 3)y = 5y
After combining like terms, the simplified expression is −3x + 5y.

A water tank holds 621 gallons but is leaking at a rate of 4 gallons per week. A second water tank holds 828 gallons but is leaking at a rate of 7 gallons per week. After how many weeks will the amount of water in the two tanks be the same?
Answer:
69 weeks
Step-by-step explanation:
Let the number of weeks be x.
The first tank holds 621 gallons is leaking at a rate of 4 gallons per week. This means that after x weeks, the amount of water in the tank is:
621 - 4x
The second tank holds 828 gallons is leaking at a rate of 7 gallons per week. This means that after x weeks, the amount of water in the tank is:
828 - 7x
After a certain amount of weeks, the amount of water in both tanks is the same. That means that:
621 - 4x = 828 - 7x
=> 7x - 4x = 828 - 621
3x = 207
x = 207 / 3 = 69
This means that the amount of water in the tank will be the same after 69 weeks.
