Happy Paws charges $16.00 plus $2.50 per hour to keep a dog during the day. Woof Watchers charges $11.00 plus $3.75 per hour. Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the variable h to represent the number of hours.
Answers
Answer:
Equation: 2.5x + 16 = 3.75x + 11
Hours: 4
Step-by-step explanation:
Hi,
The equation would be...
2.5x + 16 = 3.75x + 11
(To find the solution, you have to set the equations equal to each other)
2.5x is the cost per hour at Happy Paws and the 16 is the charge. For Woof Watchers, the 3.75x is the cost per hour and the 11 is the charge.
Now solve...
2.5x + 16 = 3.75x + 11
Subtract 16 on both sides...
2.5x = 3.75x - 5
Subtract 3.75x on both sides...
-1.25x = -5
Divide by -1.25 on both sides...
x = 4
So at 4 hours, both services will have an equal total of cost.
Hope this helps :)

Step-by-step explanation:
Andy used to charge $20, now he charged $24. $24, (The new price) / $20, (The old price) = 1.2, now multiply 1.2 * 100 = 120%. Then, 120% from the 100% initial value leaves you with a 20% increase.

2. After investing for 4 years at 5.60% interest, your $1,200 investment will have grown to $1,492
3. Solving our equation:
r = (1/18)((218/200) - 1) = 0.005
r = 0.005
Converting r decimal to R a percentage
R = 0.005 * 100 = 0.5%/month
Calculating the annual rate
0.5%/month × 12 months/year = 6%/year.
The interest rate required to get a total amount, principal plus interest, of $218.00 from simple interest on a principal of $200.00 over 1.5 years (18 months) is 0.5% per month.
4. Solving our equation:
r = (1/5)((1310/1000) - 1) = 0.062
r = 0.062
Converting r decimal to R a percentage
R = 0.062 * 100 = 6.2%/year
The interest rate required to get a total amount, principal plus interest, of $1,310.00 from simple interest on a principal of $1,000.00 over 5 years is 6.2% per year.
5. Calculation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation
t = (1/0.04)((810/750) - 1) = 2
t = 2 years
The time required to get a total amount, principal plus interest, of $810.00 from simple interest on a principal of $750.00 at an interest rate of 4% per year is 2 years.
6. First, converting R percent to r a decimal
r = R/100 = 5.5%/100 = 0.055 per year,
then, solving our equation
t = (1/0.055)((3325/2500) - 1) = 6
t = 6 years
The time required to get a total amount, principal plus interest, of $3,325.00 from simple interest on a principal of $2,500.00 at an interest rate of 5.5% per year is 6 years.
7. Solving our equation:
r = (1/6)((515.75/500) - 1) = 0.00525
r = 0.00525
Converting r decimal to R a percentage
R = 0.00525 * 100 = 0.525%/month
Calculating the annual rate
0.525%/month × 12 months/year = 6.3%/year.
The interest rate required to get a total amount, principal plus interest, of $515.75 from simple interest on a principal of $500.00 over 0.5 years (6 months) is 0.525% per month.

Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 5(m∠Y) − 150°. Find m∠Y.
Answers
Answer:
∠s + ∠y are complementary
∴ ∠s + ∠y = 90°
∠s = 4(∠y ) -100
s + y = 90
4y - 100 + y = 90
5y = 90 + 100
5y = 190
y = 38
Ans: y = 38°

In the figure, angle ABC and angle ADB are each right angles. Additionally, AC = 17.8 units and AD = 5 units. What is the length of segment DB?
Answers
Answer:
DB = 8
Step-by-step explanation:
Δ ADB and Δ BDC are similar so ratios of corresponding sides are equal, that is
[tex]\frac{DB}{DC}[/tex] = [tex]\frac{AD}{BD}[/tex] , substitute values
[tex]\frac{DB}{17.8-5}[/tex] = [tex]\frac{5}{BD}[/tex]
[tex]\frac{DB}{12.8}[/tex] = [tex]\frac{5}{BD}[/tex] ( cross- multiply )
DB² = 64 ( take the square root of both sides )
DB = [tex]\sqrt{64}[/tex] = 8
The length of segment DB is 8 units.
From the given right triangle we can deduce the following;
triangle ABD and triangle DBC are similar triangleslength AC = 17.8 unitslength AD = 5 unitsFrom the corresponding triangle rules, we can calculate the length of DB by considering the following ratios;
[tex]\frac{DB}{DC} = \frac{AD}{DB} \\\\DB^2 = AD\times DC\\\\DB^2 = 5 \times (17.8-5)\\\\DB^2 = 5 \times 12.8\\\\DB^2 = 64\\\\DB = \sqrt{64} \\\\DB = 8 \ units[/tex]
Thus, the length of segment DB is 8 units.
