A specific shade of red nail polish requires 7 parts red to 2 parts yellow. A mixture contains 35 quarts or red and 8 quarts of yellow. How can you fix the mixture to make the correct shade of red?

Answers

Answer: add 2 more yellow

Step-by-step explanation:

use the ratio 7 to 2 to solve for 35 to x

[tex]\frac{7}{2} =\frac{35}{x} \\70=7x\\x=10[/tex]

for 35 quarts of red, you will need 10 quarts of yellow to keep the ration proportional. Since it has 8 parts yellow, you need to add 2 more yellow

You can fix the mixture to the correct shade of red by adding 2 more quarts of yellow since the ratio of red to yellow should be 7:2 when you times that ratio by 5 the correct amount to make the specific shade of red would be 35:10

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 units

From 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.

1. After investing for 3 years at 7% interest, your $400 investment will have grown to $490.02
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.

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 :)

Answers

Answer:

[tex]\Huge\boxed{x=29}[/tex]

Step-by-step explanation:

Hello There!

Once again the angles shown are supplementary angles meaning that the sum of the measure is equal to 180

so we use this equation to solve for x

180 = x + 4x + 35

step 1 combine like terms

x + 4x = 5x

now we have 180=5x+35

step 2 subtract 35 from each side

180 - 35 = 145

35 -35 cancels out

now we have 145 = 5x

step 3 divide each side by 5

5x/5=x

145/5=29

we're left with x = 29

Answer:

(×+35)+4×=180°[sum of angles in a str. line ]

5×=180-35

5×=145

5x/5=145/5

x=29
