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:

x = 8.4

Step-by-step explanation:

For the 51° angle, 5.3 is the adjacent leg.

x is the hypotenuse.

cos 51° = adj/hyp

cos 51° = 5.3/x

x = 5.3/cos 51°

x = 8.4

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

50% of 60 minutes is 30 minutes

0.50 * 60 = 30

10% of 60 minutes is 6 minutes

0.10 * 60 = 6

0.75 * 60 = 45

the order is, 65% of 80, 170% of 30, 82% of 50

0.65 * 80 = 52

0.82 * 50 = 41

Answer:

18

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:

  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.

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:

[tex]y\leq \dfrac12x+3[/tex]

Step-by-step explanation:

[tex]\sf slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{0-3}{-6-0}=\dfrac12[/tex]

point-slope form of linear equation:  [tex]\sf y-y_1=m(x-x_1)[/tex]

[tex]\implies \sf y-0=\dfrac12(x-(-6))[/tex]

[tex]\implies \sf y=\dfrac12x+3[/tex]

Solid line : ≤ or ≥

Dashed line: < or >

Therefore as the line is solid, and the shading is below the line,

[tex]\implies \sf y\leq \dfrac12x+3[/tex]

Slope:-

[tex]\\ \tt\Rrightarrow m=\dfrac{4-3}{2}=1/2[/tex]

Equation of line in point slope form

[tex]\\ \tt\Rrightarrow y=1/2x+3[/tex]

Equation of shaded region

Answer:  x = 5

Step-by-step explanation:

(3x + 22) and (3x + 128) are supplementary angles, which means that they add up to 180, so we can write our equation.

(3x + 22) + (3x + 128) = 180

   3x + 22 + 3x + 128 = 180

                   6x + 150 = 180

                             6x = 30

                                x = 5
