Priya is buying raisins and almonds to make trial mix. Almonds cost $5.20 per pound and raisins cost $2.75 per pound. Priya spent $11.70 buying almonds and raisins. The relationship between pounds of almonds,a,pounds of rasins,r,and the total coast is represented by the equation 5.20a+2.75r=11.70 How many pounds of rasins did Priya buy if she bought 1.5 pounds of rasins

Answer:

To answer this u need the formula v=pi r^2h. Since r=9 and h= 2, we could solve the equation by plugging in the variables. v= (3.14)(9)^2(2) is equal to 508.94

Answer: 29.7 pounds

Step-by-step explanation:

The expression in question is w/6.

If the weight of an object on earth is w, the weight of the object on the moon is w/2.

The weight of the space suit is therefore:

= 178.2/6

= 29.7 pounds

Answer:

Equation of line passing through (3,2) and parallel to line [tex]y = \frac{1}{3}x-3[/tex] is:

[tex]y = \frac{1}{3}x+1[/tex]

Step-by-step explanation:

Given equation of line is:

[tex]y = \frac{1}{3}x-3[/tex]

Slope-intercept form of a line is given by:

[tex]y = mx+b[/tex]

Comparing the given equation of line with general form we get

m = 1/3

Let m1 be the slope of line parallel to given line

Then the equation of line will be:

[tex]y = m_1x+b[/tex]

We know, "Slopes of two parallel lines are equal"

Which means

[tex]m_1 = m\\m_1 = \frac{1}{3}[/tex]

Putting the value of slope

[tex]y = \frac{1}{3}x+b[/tex]

Putting the point (3,2) in the equation

[tex]2 = \frac{1}{3}(3)+b\\2 = 1+b\\b = 2-1\\b = 1[/tex]

Final equation of line is:

[tex]y = \frac{1}{3}x+1[/tex]

Hence,

Equation of line passing through (3,2) and parallel to line [tex]y = \frac{1}{3}x-3[/tex] is:

[tex]y = \frac{1}{3}x+1[/tex]

Answer:

[tex]P(flight \: will \: be \: on \: time) = 94\% \\ = \frac{94}{100} \\ 0.94[/tex]

(94-100)%= 6%

6% is the probability of a flight not arriving on time.

Answer:

Option C

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Given

x² + 6x

To complete the square

add ( half the coefficient of the x- term )² to x² + 6x

x² + 6x + (3)²

= x² + 6x + 9

= (x + 3)²

Answer:

[tex]-3, -2, -0.8, -\frac{1}{10} ,\frac{1}{2}, 0.8, 7[/tex]

Step-by-step explanation:

Given

[tex]7, -3, \frac{1}{2}, -0.8, 0.8, -\frac{1}{10}, -2[/tex]

Required

Order from least to greatest

[tex]7, -3, \frac{1}{2}, -0.8, 0.8, -\frac{1}{10}, -2[/tex]

Convert 1/2 and -1/10 to decimals

[tex]7, -3, 0.5, -0.8, 0.8, -0.1, -2[/tex]

Negative numbers are always the least of all numbers.

In the given list, the negative numbers are:

[tex]-3, -0.8, -0.1, -2[/tex]

The higher the magnitude of a negative number, the smaller it is.

--------------------------------------------------------------------------------------------

Take for instance: -7 and -8.

-8 has a magnitude of 8 and -7 has a magnitude of 7.

Because 8 > 7 (the magnitudes), then

-8 < -7

--------------------------------------------------------------------------------------------

Using the above analysis:

[tex]-3, -0.8, -0.1, -2[/tex] from least to greatest is:

[tex]-3, -2, -0.8, -0.1[/tex]

Considering the positive numbers:

[tex]7, 0.5, 0.8[/tex]

From least to greatest, it is:

[tex]0.5, 0.8, 7[/tex]

Merge the negative and the positive numbers:

[tex]-3, -2, -0.8, -0.1,0.5, 0.8, 7[/tex]

Convert 0.5 and -0.1 back to fractions

[tex]-3, -2, -0.8, -\frac{1}{10} ,\frac{1}{2}, 0.8, 7[/tex]

notice that the 841 and the 400 don't go squared because they already squared!

Answer:

a. The maximum revenue Luci can make selling cookies in one day is $2,000.

b. The price she should sell the cookies for her to make the maximum revenue is $1.

Step-by-step explanation:

Note: This question is not complete. The complete question is therefore provided before answering the question as follows:

Luci Lulu opened a cookie store in the mall. She found that the relationship between the price of a cookie, p, and the number of cookies sold, x, is given by the linear relationship x = −2000 p + 4000. Find the maximum revenue Luci can make selling cookies in one day. Find the price she should sell the cookies for to make the maximum revenue.

The explanation of the answer is now provided as follows:

Given;

x = −2000p + 4000 …………………………. (1)

The revenue function is obtained as follows:

R = px ……………………….. (2)

Substitute equation (1) into (2), we have:

R = p(−2000p + 4000)

R = −2000p^2 + 4000p ……………… (3)

Obtain the derivative of equation (3), set to zero and solve for p, we have:

−4000p + 4000 = 0

4000 = 4000p

p = 4000 / 4000

p = 1

From the above, p = 1 implies that the price that ensure maximum revenue is $1.

We can now answer as follows:

a. Find the maximum revenue Luci can make selling cookies in one day.

Since p = 1 implies that the price that ensure maximum revenue is $1, we then substitute p = 1 into equation (3) as follows:

R = (−2000 * 1^2) + (4000 * 1)

R = (−2000 * 1) + (4000 * 1)

R = −2000 + 4000

R = 2000

Therefore, the maximum revenue Luci can make selling cookies in one day is $2,000.

b. Find the price she should sell the cookies for to make the maximum revenue.

Since p = 1 implies that the price that ensure maximum revenue is $1 as obtained above, it therefore implies that the price she should sell the cookies for her to make the maximum revenue is $1.

Answer:

Please check the explanation.

Step-by-step explanation:

Show that 4x - x² - 7 is always negative.

Given

4x - x² - 7

4x - x² - 7 is always negative because:

Hence, 4x - x² - 7 is always negative

For example,

let suppose we enter x = 1

[tex]4(1)-1^{2} -7\\=4-1-7\\=4-8\\=-4[/tex]

let suppose we enter x = -1

[tex]4(-1)-(-1)^{2} - 7\\= -4 - 1 - 7\\= -12[/tex]

Answer:

C

Step-by-step explanation:

Given

[tex]\frac{2}{3}[/tex] m + 5 = 17 ( subtract 5 from both sides )

[tex]\frac{2}{3}[/tex] m = 12 ( multiply both sides by 3 to clear the fraction )

2m = 36 ( divide both sides by 2 )

m = 18 → C

Answer:

Answer:

A,C,E

Step-by-step explanation:

Answer:

B. n ≥ -24.

D. The circle is closed.

E. The arrow points right.

Step-by-step explanation:

Step 1: Multiply both sides by -3/2, the reciprocal of -2/3. Since -2/3 is negative, the inequality direction changes.

(-2/3 * -3/2)n ≤ 16(-3/2)

n ≥ 16(-3/2)

Step 2: Express 16(-3/2) as a single fraction.

n ≥ 16(-3)/2

Step 3: Multiply 16 by -3 to get -48.

n ≥ -48/2

Final Step: Divide -48 by 2 to get -24.

n ≥ -24 is the final answer.

With inequalities that have this (≥), the circle should be closed (D) and the arrow goes right (E).

Answer:

51

Step-by-step explanation:

Answer: 51

Step-by-step explanation:

Use PEMDAS. First solve inside the parentheses. You will get 43 + (4) x 2. Then, do the multiplication (4x2). You will have 43+8. And that can be simplified to 51. Hope this helps!

Answer:

Depends. If you were asking 2+-9/2, according to the rules of PEMDAS it would be -2.5 but by the way you wrote that, I'm assuming you meant (2+-9)/2 which is -3.5.
