Answer:

10 more seed packets.

Step-by-step explanation:

36/9=4 so there are 4 seeds in each packet. If she already has 36 plants, she only need 40 more to get the 76 she wants. 40/4=10 so she needs 10 more seed packets.

Answer: 42.9%

Step-by-step explanation:

The percentage increase of the fat content will be calculated as:

= Fat increase / Previous fat content × 100

= (30 - 21) / 21 × 100.

= 9/21 × 100

= 42.9%

x^2 + 8x

Answer:

cost to make paper signs = $1

cost to make laminated signs = $2

Step-by-step explanation:

Let

x = cost to make paper signs

y = cost to make laminated signs

8x + 2y = 12 (1)

10x + 10y = 30 (2)

Multiply (1) by 5

40x + 10y = 60 (3)

10x + 10y = 30 (2)

Subtract (2) from (3) to solve for x

40x - 10x = 60 - 30

30x = 30

x = 30/30

x = $1

Substitute x = 1 into (1)

8x + 2y = 12

8(1) + 2y = 12

8 + 2y = 12

2y = 12 - 8

2y = 4

y = 4/2

y = $2

cost to make paper signs = $1

cost to make laminated signs = $2

Answer:

Yesterday I squeezed 2 kilos of apples in a barrel.

Today I have picked 5 extra kilos of apples and save them in a basket.

By the end of the day, I want to squeeze some of them and add to the barrel.

Apple juice from the barrel is valued 3 times the same amount of raw apples.

I want to find how many apples I can squeeze today (x) such that the value of the remaining raw apples is equivalent to the total value of produced apple juice.

Step-by-step explanation:

The equation is 5-x = 3 * (x + 2).

If x is the amount of apple to squeeze (in kilos) then 5-x is the remaining raw apples and x+2 is the total quantity of juice.

Since that juice is valued 3 times the raw apples we obtain the equivalence defined in the equation above.

Answer:

16

Step-by-step explanation:

To solve plugin -3 for n

[tex]-3^2+7[/tex]

Then, solve using PEMDAS. First, do exponents

Answer:

[tex]\frac{4}{15}+\:\frac{1}{2}[/tex] in the simplest term is:

[tex]\frac{4}{15}+\frac{1}{2}=\frac{23}{30}[/tex]

Step-by-step explanation:

Given the expression

[tex]\frac{4}{15}+\:\frac{1}{2}[/tex]

Thus, solving to reduce to the simplest term

[tex]\frac{4}{15}+\frac{1}{2}[/tex]

LCM of 15, 2: 30

Adjusting fraction based on the LCM

so the expression becomes

[tex]\frac{4}{15}+\:\frac{1}{2}=\frac{8}{30}+\frac{15}{30}[/tex]

Apply the fraction rule:      [tex]\frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}[/tex]

            [tex]=\frac{8+15}{30}[/tex]

Add the numbers: 8+15 = 23

            [tex]=\frac{23}{30}[/tex]

Therefore, [tex]\frac{4}{15}+\:\frac{1}{2}[/tex] in the simplest term is:

[tex]\frac{4}{15}+\frac{1}{2}=\frac{23}{30}[/tex]

Answer:

The robot can clean the room without recharging.

Step-by-step explanation:

Given:

After a robot vacuum is fully charged, it can run for [tex]15[/tex] minutes.

The robot cleans [tex]\frac{1}{2}[/tex] square foot every second.

To find: If the charged robot can clean a room that is [tex]400[/tex] square feet without recharging.

Solution:

Area cleaned by the robot in [tex]1[/tex] second [tex]=\frac{1}{2}[/tex] square foot.

We know that, [tex]1[/tex] minute [tex]=60[/tex] seconds.

So, [tex]15[/tex] minutes [tex]=15\times 60=900[/tex] seconds.

Now, area cleaned by the robot in [tex]900[/tex] seconds [tex]=\frac{1}{2} \times 900=450[/tex] square feet.

The area to be cleaned is [tex]400[/tex] square feet.

Hence, the robot can clean the room without recharging.

Step-by-step explanation:

The unit rate of the snail's movement is 3 inches per minute.

Important information:

We need to find the unit rate.

Divide the distance by time to find the unit rate.

[tex]\text{Rate}=\dfrac{24}{8}[/tex]

[tex]\text{Rate}=3[/tex]

Therefore, the unit rate of the snail's movement is 3 inches per minute.

Step-by-step explanation:

Simplify : 7r/ 2 ÷ 14r²/3

7r/ 2 ÷ 14r²/3

Changing the ÷ sign to multiplication :

Multiply 7r/2 by the reciprocal of the denominator :

7r/ 2 * 3/14r²

((7 * r) / 2) * (3) / 14 * r * r

= 3 / 4r

Answer:

Kristen bought 2 fancy shirts and 5 plain t-shirts.

Step-by-step explanation:

Given that,

Kristen spent $131 on 7 shirts.

Cost of one fancy shirt = $28

Cost of one plain t-shirt = $15

Let,

x be the number of fancy shirts

y be the number of plain t-shirts

x+y = 7       Eqn 1

28x+15y=131    Eqn 2

Multiplying Eqn 1 by 15

15(x+y=7)

15x+15y=105    Eqn 3

Subtracting Eqn 3 from Eqn 2

(28x+15y)-(15x+15y)=131-105

28x+15y-15x+15y=26

13x=26

Dividing both sides by 13

[tex]\frac{13x}{13}=\frac{26}{13}\\x=2[/tex]

Putting x=2 in Eqn 1

2+y=7

y=7-2

y=5

Hence,

Kristen bought 2 fancy shirts and 5 plain t-shirts.
