Answer:

Total Price is $410.75 and the tax rate is 0.0953

Step-by-step explanation:

Step 1:  Determine how much she paid

Initial Price of Dress + Tax on the Dress

$375.00 + $35.75

$410.75

Step 2:  Determine the tax rate

(Tax) / (Price Before Tax)

($35.75) / ($375.00)

0.0953

Answer:  Total Price is $410.75 and the tax rate is 0.0953

Answer:

question is incomplete. A complete question is ----> Diana is painting statues. She has 7/8 of a liter of paint remaining. Each statue requires 1/16 of a liter of paint. find the number of statues.

each statue requires 1/16th of a liter of paint.

so, in a liter , 16th statues can be painted by Diana.

but A/C to question,

she has 7/8 of a liter of paint remaining.

so, we have to find how many statues she can paint in 7/8 litres.

so, number of statues = 7/8 × 16 = 14

Answer:$51

Step-by-step explanation:

Answer:When two things are proportional, they always change together at the same rate. This relationship can be represented by an equation like y = kx, where k is a constant number that shows how the two things are related.

Step-by-step explanation:

Two quantities are proportional if they always change at the same rate. For example, if you travel at a constant speed, your distance is proportional to your time. If you double your time, you double your distance.

We can represent proportional relationships with an equation of the form y = kx, where y is one quantity, x is the other quantity, and k is a constant of proportionality.

The constant of proportionality k represents the factor by which one quantity changes for a given change in the other quantity. For example, if your speed is 60 mph when you travel 10 miles, the constant of proportionality is 6, which means your speed increases by 6 mph for each additional mile you travel.

To find the constant of proportionality k, you can divide any value of y by the corresponding value of x. For example, if you know that when x = 2, y = 8, then k = y/x = 8/2 = 4.

The equation y = kx can be used to predict one quantity if you know the other quantity. For example, if you know that y = 24 when x = 6, you can use the equation to find k = y/x = 24/6 = 4, and then predict that y = kx = 4*8 = 32 when x = 8.

Answer:

the third answer

Step-by-step explanation:

Answer:

-2/45

Step-by-step explanation:

First, make term a into an improper fraction:

\(a=1\frac{3}{5} =\frac{8}{5}\)

Now, plug in all terms to the equation:

\(\frac{-|\frac{8}{5}+(-2)|}{2-(-7)}\)

Simplify the Numerator:

\(\frac{-|-\frac{2}{5}| }{2-(-7)}\)

Note that the absolute value of a negative value is the same positive value:

\(\frac{-|\frac{2}{5}| }{2-(-7)}\)

Simplify the Denominator:

\(\frac{-|\frac{2}{5}| }{9}\)

Now Simplify: (You can remove the absolute value at this point)

\(\frac{-\frac{2}{5} }{\frac{9}{1} }\)

Simplify:

\(-\frac{2}{5}*\frac{1}{9}=\frac{-2}{45}\)

Therefore, your anwer is -2/45

Hey there!

The answer to your question is x = 45

To solve this, we want to get x with a coefficient of 1 by itself on one side of the equal sign, and right now it's coefficient is 1/3. We can get a coefficient of 1 by multiplying both sides of the equation by 3.

15(3) = 1/3x(3)

45 = x

Answer: The y-intercept is the initial amount Tammy earns.

Step-by-step explanation:

Always remember that for graphs, the y-intercept is the initial amount. In this case, it would be the initial amount or the very first amount Tammy earns. If the line goes through the origin (0,0), that means that Tammy earns $0.00 for 0 hours of working.

3/10

Step-by-step explanation:

60% is the same as 60/100

90% is the same as 90/100

90-60=30

30/100

30/100 is divided by 10 on each side to simplify it to 3/10

I’m pretty sure the answer should be 1,710 if not i’m sorry

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210     (This is because 15% of x is added in x to become    
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400


Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400     (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
                                                                               = 1710 fish

Answer:

∠ ABC = 87°

Step-by-step explanation:

∠ ABD and ∠ DBE are adjacent angles and are supplementary, sum to 180° , so

2x - 17 + x + 32 = 180 , that is

3x + 15 = 180 ( subtract 15 from both sides )

3x = 165 ( divide both sides by 3 )

x = 55

Then

∠ DBE = x + 32 = 55 + 32 = 87° , thus

∠ ABC = ∠ DBE ( vertical angles  )

∠ ABC = 87°

The total distances you traveled to reach your destination on each day of your three-day trip are as follows:

a) Day 1 = 40 miles

b) Day 2 = 30 miles

c) Day 3 = 11 miles.

The total distances are determined using proportions.

Proportion refers to the fractional value of the whole number or quantity.

a) Day 1:

The fractional distance traveled = ⁵/₈

The remaining distance to travel = 15 miles

15 miles = ³/₈ (1 - ⁵/₈)

Proportionately, the total distance = 40 miles (15 ÷ ³/₈)

b) Day 2:

The distance traveled = 18 miles

The remaining distance to travel = ²/₅

The distance traveled = ³/₅ (1 - ²/₅)

³/₅ = 18 miles

Proportionately, the total distance = 30 miles (18 ÷ ³/₅)

c) Day 3:

The distance traveled = ⁵/₁₁

The distance to travel = 6 miles

The distance to travel in fractions = ⁶/₁₁ (1 - ⁵/₁₁)

Proportionately, if 6 miles = ⁶/₁₁, the total distance = 11 miles (6 ÷ ⁶/₁₁)

Answer:

The total weight of the packages would be 43.875.

Step-by-step explanation:

The total weight of the packages would be 43.875 because all you have to do is add each amount to get the total. So, you would do 14.125 + 12.35 + 17.4 to equal 43.875.

Answer:

I think that is correct

Step-by-step explanation:

Answer:

1 1/5.

Step-by-step explanation:

To divide a fraction by another fraction you have to change the equation like "Keep, Switch, Flip".

For the problem 24/25 ÷ 4/5,

You KEEP the first fraction as is, so 24/25

Then, you SWITCH the sign from division to multiplication.

Finally, you FLIP the second fraction upside down, (the reciprocal). So it's 5/4.

The equation is now 24/25 * 5/4, which we can just multiply the numerators  and denominators. (or cross cancel first)

24 * 5 = 120

25 * 4 = 100

the fraction is 120/100. Simplified, it can be divided by 10 to make 12/10, and finally divided by 2 to make 6/5, or 1 1/5.

Answer:

Step-by-step explanation:

4.

a)

P = 2width + 2length

8x = 2x + 2 length; 8x-2x = 2 length; 6x=2 length

length = 3x

b)

sides= 1/4 of 3x = 3x/4

perimeter of square = 4* side = 4*3x/4 = 3x

c)

x= 4

P rectangle =8x= 8*4= 32

P square = 3x = 3*4 = 12

32-12 = 20 cm greater is the P rectangle than P of square

d)

A rectangle = 2x*x = 2*4*4 = 32

A square =(3x/4)² = (3*4/4)² = 9

32-9 = 23 cm² greater is the A rectangle than A of square
