Answer:

Step-by-step explanation:

The pumpkin gained 372 -141 = 231 pounds in 7 weeks, or an average of ...

  (231 lb)/(7 wk) = 33 lb/wk

The pumpkin gained 33 pounds per week.

__

In the 3 weeks after the pumpkin plant was chosen, it would have gained 3×33 = 99 pounds. It weighed 141 pounds at that point, so must have had an initial weight of 141 -99 = 42 pounds at t=0. The weight of the pumpkin can be modeled as ...

  W = 33t +42

Answer:

x = 14/3

Step-by-step explanation:

3(x+4)=26

Distribute

3x+12 =26

Subtract 12 from each side

3x+12-12 = 26-12

3x = 14

Divide each side by 3

3x/3 =14/3

x = 14/3

Step-by-step explanation:

x+4= 26/3

x= 26/3 _4

x=26_12/3

x=14/3

Answer:

the answer is 40%.

Step-by-step explanation:

probability= total number of juniors all over total number.

that is , 8

rounding it the nearest whole percent is

2 × 100

40%.

The probability that the selected student is a junior is 27%.

The probability of an event is the ratio of the number of outcomes favorable to the event to the total number of outcomes for the event. This represents the chance for the event to take place.

If A is the event, n is the number of outcomes favorable to the event and S is the total number of outcomes, then the probability of the event A is given as:

P(A) = n/S.

We are given a two-way table showing the number of freshmen, sophomores, juniors, and seniors in the class with respect to their gender.

We are asked to find the probability of selecting a junior student while picking a random student from the class.

Let the event of selecting a junior student from the class be A.

Number of favorable outcomes to event A (n) = 2 + 6 = 8 (junior males + junior females)

Total number of outcomes (students in the class) (S) = 4 + 6 + 2 + 2 + 3 + 4 + 6 + 3 = 30.

∴ The probability that the selected student is a junior is given by:

P(A) = n/S = 8/30

or, P(A) = (8/30)*100% = 26.67% = 27% (rounding to the nearest whole percent).

∴ The probability that the selected student is a junior is 27%.

Answer:

p = 72

q = 18

Step-by-step explanation:

Complementary means they add to  90o

p + q = 90

p = 4*q

Substitute 4q for p

4q + q = 90            Combine

5q = 90                  Divide by 5

5q/5 =90/5

q = 18

p = 4q

Number 4 is addition

Answer:

A. 17°

Step-by-step explanation:

Recall: measure of an inscribed angle = ½(intercepted arc)

Inscribed angle = m<MTH

Intercepted arc = arc MH = 34°

Therefore,

m<MTH = ½(Arc MH)

Substitute

m<MTH = ½(34)

m<MTH = 17°

Answer:

3

Step-by-step explanation:

5(11x-2) = 155

⇔ 55x - 10 = 155

⇔ 55x = 155 + 10

⇔ 55x = 165

⇔ x = [tex]\frac{165}{55}[/tex]

⇔ x = 3

Answer:

x=3

Step-by-step explanation:

5(11x - 2) = 155

Divide each side by 5

5/5(11x - 2) = 155/5

11x-2 = 31

Add 2 to each side

11x-2+2 = 31+2

11x=33

Divide by 11

11x/11 = 33/11

Answer:

A, D, & F

Step-by-step explanation:

When you distribute, you get 6a + 5a + 5 - 3a + 21.

After combining like terms, you get 8a + 26.

Lastly, all you have to do is figure out which expressions are equivalent to

8a + 26.

A) 8a + 26 = 8a + 26

D) 6a + 5a + 5 - 3a + 21 (combine like terms) = 8a + 26

F) 2(4a + 13) - Simple distribution

2 x 4a = 8a

2 x 13 = 26

2(4a + 13) = 8a + 26

Step-by-step explanation:

a) The problem requires maximizing the total value from sandwich fruits and drink, therefore the objective function is associated to the sum of the values of each value.

We have three variables xi  ( x₁, x₂, x₃ ) the values of sandwich, fruits and drink, and we have to maximize such quantities subject to the constraint of size (the capacity of the basket)

b) z  = 6*x₁  +  4*x₂  + 6*x₃      Objective Function

Constraint :

basket capacity  17

9*x₁  +  3*x₂  +  4*x₃  ≤  17

General constraints:

x₁   ≥  0     x₂    ≥  0     x₃  ≥  0    all integers

e) z (max) = 24

x₁  =  x₂  = 0     x₃  = 4

Answer:

[tex]x = 24[/tex] ---- Hao Sheng

[tex]y =51[/tex] --- His father

[tex]z = 84[/tex] ---- His grandfather

Step-by-step explanation:

Given

[tex]x \to Hao\ Sheng[/tex]

[tex]y \to his\ father[/tex]

[tex]z \to his\ grandfather[/tex]

From the question, we have:

[tex]\frac{x + y + z}{3} = 53[/tex] --- The average of their age

[tex]\frac{z}{2} + \frac{y}{3} +\frac{x}{4}= 65[/tex]

[tex]z - 4 = 4(x - 4)[/tex] --- 4 years ago

Required

Their current age

[tex]z - 4 = 4(x - 4)[/tex]

Open bracket

[tex]z -4 = 4x-16[/tex]

Make z the subject

[tex]z = 4x-16+4[/tex]

[tex]z = 4x-12[/tex]

Multiply [tex]\frac{z}{2} + \frac{y}{3} +\frac{x}{4}= 65[/tex] by 12

[tex]6z + 4y + 3x = 780[/tex]

Substitute [tex]z = 4x-12[/tex] in [tex]6z + 4y + 3x = 780[/tex]

[tex]6(4x - 12) + 4y + 3x = 780[/tex]

[tex]24x - 72 + 4y + 3x = 780[/tex]

Collect like terms

[tex]24x + 3x + 4y = 780+ 72[/tex]

[tex]27x + 4y = 852[/tex]

Substitute [tex]z = 4x-12[/tex] in [tex]\frac{x + y + z}{3} = 53[/tex]

[tex]\frac{x + y + 4x - 12}{3} = 53\\[/tex]

Multiply through by 3

[tex]x + y + 4x - 12 = 159[/tex]

Collect like terms

[tex]x + 4x + y = 159+12[/tex]

[tex]5x + y = 171[/tex]

Make y the subject

[tex]y = 171 - 5x[/tex]

Substitute [tex]y = 171 - 5x[/tex] in [tex]27x + 4y = 852[/tex]

[tex]27x + 4(171 - 5x) = 852[/tex]

[tex]27x + 684 - 20x = 852[/tex]

Collect like terms

[tex]27x - 20x = 852-684[/tex]

[tex]7x = 168[/tex]

Divide by 7

[tex]x = 24[/tex]

Solve for y in [tex]y = 171 - 5x[/tex]

[tex]y =171 -5*24[/tex]

[tex]y =171 -120[/tex]

[tex]y =51[/tex]

Solve for z in [tex]z = 4x-12[/tex]

[tex]z = 4 * 24- 12[/tex]

[tex]z = 96- 12[/tex]

[tex]z = 84[/tex]
