Lincoln and Hunter work at a dry cleaners ironing shirts. Lincoln can iron 30 shirts
per hour, and Hunter can iron 20 shirts per hour. Lincoln and Hunter worked a
combined 15 hours and ironed 350 shirts. Determine the number of hours Lincoln
worked and the number of hours Hunter worked.

Answers

Answer 1
L=hours Lincoln worked
H=hours Hunter worked

Two unknowns , two equations


30L+20H=350

L+H=15

Solve

L=15-H


30(15-H)+20H=350

450-30H+20H=350

-10H=-100

10H=100

H=10

L=15-10=5

Lincoln worked 10 hours

Hunter worked 5 hours

Check


30*5+20*10=350

150+200=350

350=350

Answer:

9%

Step-by-step explanation:

Given data

Principal= 400

time= 4 months

r= 12%

SI= 12

SImeple interest

12=PRT/100

susbstitute

12= (400*r*4/12)/100

12SI= 400*r*0.333/100

12=133.2r/100

Determine if the following ratios form proportions.

1.) 1 to 3 and 7 to 21

2.) 3 to 4 and 24 to 18

3.)1:5 and 6:30

for brainiest:)

Answers

Answer:

1. Proportional

2. Not proportional

3. Proportional

Step-by-step explanation:

We have three questions with 2 ratios and are asked if they are proportional or not.

To define proportionality, basically its if the two ratios equal the same value when put in a certain way.

And that way is :

[tex]\frac{x}{y} =\frac{x}{y}[/tex]

You will substitute the numbers with the letters, in which you will cross multiply :

[tex]\frac{x * y}{x*y}[/tex]

So subtitute :

1.

[tex]\frac{1}{3} *\frac{7}{21}[/tex]

[tex]\frac{1*21}{7*3}[/tex]

[tex]21=21[/tex]

Therefore 1. is proportional.

2.

[tex]\frac{3}{4} *\frac{24}{18}[/tex]

[tex]\frac{4*24}{3*18}[/tex]

[tex]\frac{96}{54}[/tex]

96 = 54

Therefore 2. is not proportional.

3.

[tex]\frac{1}{5} *\frac{6}{30}[/tex]

[tex]\frac{1*30}{5*6}[/tex]

[tex]\frac{30}{30}[/tex]

30 = 30

Therefore 3. is proportional.

the price of a ring was decreased by 25% to £390. what was the price before the decrease?

Answers

Answer:

The original price was 520

Step-by-step explanation:

To find this, we first need to note that we paid 75% of the price. This is because we took 25% off from the original. Now we take the price we paid and divide it by the percentage of it which we paid. This will give us the original price.

390/75% = Total

390/.75 = Total

520 = Total

Monday

The sale price of the items was $41.40

Mrs. Bolden paid $2.48 in sales tax on her purchase.

Altogether, Mrs. Bolden paid $43.88 for the shirts and flip flops.

Tuesday

The price decreased by approximately 8%

3.44 ÷ 3.75 = 0.917

0.917 × 100 = 91.7

91.7 ≈ 92

100 - 92 = 8

8% of 3.75 is 0.3

3.75 - 0.3 = 3.45

3.45 ≈ 3.44

Wednesday

22 ¹/₂ yrs or 22 yrs if that's easier

0.085 × 100 = 8.5

100 - 8.5 = 91.5

4 1/4 = 4.25

91.5 ÷ 4.25 = 21.5294117647

21.5294117647 × 4.25 = 91.5

21.5294117647 ≈ 21 ¹/₂ yrs

If she marked up the price by 40%, that means $15 is 60% the original/selling price.

60% of x = 15

x = 25

The selling price is $25

If you wanted to confirm, 0.6 × 25 = 15

5 shirts for $27 each

5 shirts for $135

126 + 135 = 261

6.5% of 261

0.065 × 261 = 16.965

16.965 to the nearest cent is 16.97

She would have to pay $16.97 for tax.

261 + 16.97 = 277.97

She won't have enough money to buy everything she wants since the total price would be over $275.

Houa's family took a road trip to the Grand Canyon. Houa fell asleep 29% of the way
through the trip. If the total length of the trip was 800 miles, how many miles had
they travelled when Houa fell asleep?

Answers

Answer:

232 miles had travelled when Houa fell asleep.

Step-by-step explanation:

1. .29 x 800 = 232

If the total length of the trip was 800 miles then 232 miles had they travelled when Houa fell asleep.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given that Houa's family took a road trip to the Grand Canyon.

Houa fell asleep 29% of the way through the trip.

If the total length of the trip was 800 mile we need to find the number of miles they travelled when Houa fell asleep.

29% can be converted to decimal by dividing with 100

29/100=0.29

Now multiply 0.29 with 800

0.29×800

232 miles

Hence, 232 miles had they travelled when Houa fell asleep.

How do you find exact values?

Answers

Answer:

Using trigonometric identities: A trigonometric identity is a relationship between trigonometric functions that we can use to find an exact value of a trigonmetric function.Using the unit circle: The unit circle is a circle with its center at the origin and a radius of 1 unit. If we place an angle, θ, with its initial side along the positive x-axis, then the point where the angle's terminal side intersects the unit circle is (cos(θ), sin(θ)).Using reference angles: Reference angles are the smallest angle that the terminal side of an angle makes with the x-axis. As it turns out, trigonometric functions of an angle and its reference angle have the same value, except that they may have different signs.

For example, suppose we want to find the exact value of tan(405°). First, we take a look at the angle 405° on a graph with the unit circle:

in this that the reference angle of 405° is 45°. We can use the fact that tangent is positive in the first quadrant and the rule for reference angles to deduce that tan(405°) = tan(45°). Then we can use the well-known fact that tan(45°) = 1 to get that tan(405°) = 1.
