Answer:

a. The equation is s =  [tex]\frac{1}{3}[/tex]  w

b. [tex]1\frac{5}{12}[/tex]  cups of sugar will be needed to follow the recipe

Step-by-step explanation:

The equation of the direct proportional relation is y = k x, where

We can find the value of k by using the initial values of x and y

Let us use this rule to solve the question

∵ In the recipe for 1/2 cup of sugar for every 1 1/2 cups of water

→ That means the number of cups of sugar is in proportion to the

   number of cups of water

∵ s represents the number of cups of sugar

∵ w represents the number of cups of water

∴ s ∝ w ⇒ (∝ a sign of proportion)

∴ s = k w ⇒ k is the constant of proportionality

∵ s = [tex]\frac{1}{2}[/tex] and w = [tex]1\frac{1}{2}=\frac{3}{2}[/tex]

Substitute the values of s and w in the equation above to find k

∵ [tex]\frac{1}{2}[/tex] = k × [tex]\frac{3}{2}[/tex]

→ Multiply both sides by 2 to cancel the denominators

∴ 1 = 3 k

→ Divide both sides by 3 to find k

∴ [tex]\frac{1}{3}[/tex] = k

∴ The equation is s =  [tex]\frac{1}{3}[/tex]  w ⇒ a.

→ We need to find the number of sugar cups for 4 1/4 cups of water

∵ w = [tex]4\frac{1}{4}=\frac{17}{4}[/tex]

∵ s =  [tex]\frac{1}{3}[/tex]  w

→ Substitute w by 5/4

∴ s = [tex]\frac{1}{3}[/tex] × [tex]\frac{17}{4}[/tex]

∴ s = [tex]\frac{17}{12}=1\frac{5}{12}[/tex]

∴  [tex]1\frac{5}{12}[/tex]  cups of sugar will be needed to follow the recipe ⇒ b.

Answer:13/15

Step-by-step explanation:

Add 7/9 and 2/3 the answer is 13/9 then divide it by 5/3 in order for you to divide get the reciprocal of 5/3 which is 3/5 then multiply it and you well get 13/15

Answer:

13/15

Step-by-step explanation:

The answer is 13/15 because:

1) In order to figure out what 7/9 + 2/3 is, we need to find the common denominator. The common denominator is 9 because 3 contains the factor 9.

7/9 + 6/9 = 13/9

We need to multiply the denominator to get to 9: 3 x 3 = 9. We have to multiply the numerator as well: 2 x 3 = 6.

2) Next, we have to divide 13/9 and 5/3. In order to divide we have to find the reciprocal of the second number. Reciprocal means to flip the fraction. The reciprocal of 5/3 is 3/5.

3) Finally, we just have to multiply 13/9 and 3/5 which is 39/45. 39/45 in simplest form is 13/15.

Hope this helps! :D

Answer:

Yes, 9

Step-by-step explanation:

Melvin would have mowed 12/25 of the lawn of the when he takes his first break.

An equation is an expression that shows the relationship between two or more numbers and variables.

The total number of squares in the lawn = 100, 3/10 of the lawn = (3/10) * 100 = 30 squares

The number of squares already mowed = 18

Hence:

Fraction of the lawn Melvin have mowed when he takes his first break = (18 + 30) / 100 = 48/100 = 12/25

Melvin would have mowed 12/25 of the lawn of the when he takes his first break.

x = 180 - 118 ( linear angles)

x = 62

62+62+y = 180

y = 56

Answer:

Step-by-step explanation:

Angle of a straight line = 180 degrees :)

So to find x you would do:

x = 180 - 118 = 62

Also the angle sum of a triangle = 180 degrees.

Since it is an isosceles triangle, the bottom two angles would be equal:

Angle sum of triangle = 180

x + x + y = 180

Since we know x = 62, substitute it into the above equation:

62 + 62 + y = 180

124 + y = 180

Subtract 124 from both sides to solve for y.

y = 180 - 124

y = 56

Answer:

The original price is $7926.83

Step-by-step explanation:

Step 1: Subtract the percent of the discount from the percent of the original cost:

100% - 18% = 82%

Step 2: Convert the percent to a decimal.

82% = 0.82

Step 3: Solve for the original price.

[tex]\frac{0.82x}{0.82} = \frac{6500}{0.82}[/tex]

Answer:

144 fluid ounces

Step-by-step explanation:

Let's solve for x

9(2x+1) < 9x - 18

18x+9 < 9x-18

18x-9x < -18-9

9x < -27

x < -27/9

x < -3

Any value smaller than -3 is in the solution set

That means we have {-4, -5, -6, ...} as our solution set if x was only allowed to be an integer.

We can rule out choices B through D because of this. Only choice A remains, which I'm assuming you meant to say -4 instead of simply 4. If choice A says -4, then this is the answer.

If it doesn't say -4, then that isn't the answer and none of the answer choices work.

Note: if your original inequality is [tex]9(2x+1) \le 9x-18[/tex] then it solves to [tex]x \le -3[/tex] allowing x = -3 to be part of the solution set now. If you have an "or equal to" then that means B) -3 is the answer.

It seems like there might be a typo somewhere so I would double check.

Answer:

Step-by-step explanation:

f(x) = y = x² + 2x = x(x + 2)

the y-intercept (the point with the y value where x = 0) is

y = 0² + 2×0 = 0

yes, the y-intercept is (0, 0).

yes, the graph opens upward, as x² is the most powerful and therefore driving term in the expression. so, it behaves basically like x².

no, the x-intercepts are the points, where y = 0.

and while (0, 0) is correct, but (2, 0) is not.

x = 2 gives us 2² + 2×2 = 4 + 4 = 8 as y value.

the second correct x-intercept would be (-2, 0).

x = -2 gives us (-2)² + 2×-2 = 4 - 4 = 0

no (see last point)

yes, the vertex is (-1, -1).

we get the extreme value (in this case the minimum, as the curve opens upward) by finding the zero of the first derivative :

f'(x) = 2x + 2 = 0

2x = -2

x = -1

y = (-1)² + 2×-1 = 1 - 2 = -1

Answer:

  a. $4307.96

  b. 4.76 years

  c. $0.99

Step-by-step explanation:

These questions can be answered using the relevant formulas for future value of an investment.

For compound interest, the account balance is given by ...

  A = P(1 +r/n)^(nt) . . . . principal P at annual rate r compounded n times per year for t years

$4000 at 2.48% compounded quarterly for 3 years will give an account balance of ...

  A = $4000(1 +0.0248/4)^(4·3) = $4000×1.0062^12 ≈ $4307.96

After 3 years, there will be $4307.96 in the account.

__

After earning $500 in interest, the account balance will be $4500. That means we need to solve for t such that ...

  4500 = 4000(1.0062^(4t))

  log(4500/4000)/(4×log(1.0062)) = t ≈ 4.764

It will take about 4.76 years to earn $500 interest.

__

The future value of an account with continuous compounding is given by ...

  A = Pe^(rt)

  A = $4000e^(0.0248·3) ≈ $4308.95

Then the additional interest is ...

  $4308.95 -4307.96 = $0.99

If the money is compounded continuously, there will be $0.99 more in the account after 3 years.
