Answer:

17

Step-by-step explanation:

Let F be the number of fruit per acre  

F = (25 + x) × (41 - x)  

F=1025 -25x + 41x -x²

F=-x²+16x+1025

The maximum yield is at the maximum of that expression, which is at

[tex]x=-\frac{b}{2a} =>-\frac{16}{-2\times1}[/tex]

x=8

So apparently she currently has far too many trees per acre. To get the maximum yield, she needs to reduce the number of trees per acre by 8.

So the number of trees per acre for maximum yield is 25-8 = 17.

Answer:

7 + 2 + 5 = 143547

Step-by-step explanation:

This question needs to identify the pattern

the pattern

is

5 + 3 + 2 = 151022

First two digits: 5*3 = 15   multiple of first and second term

third and fourth digit: 5*2 = 10 multiple of first and third term

last two digit = First two digits + third and fourth digit - second term

                    = 15+10 - 3 = 22

similarly

9 + 2 + 4 = 183652

9*2 = 18

9*4 = 36

18+36 - 2 = 52

____________________________________

5 + 4 + 5 = 202541

5*4 = 20

5*5 = 25

20+25-4 = 41

_______________________

7 + 2 + 5 = ??????​

7*2 = 14

7*5 = 35

14+35-2 = 49-2 = 47

thus, 7 + 2 + 5 = 143547

Answer:

niamah : jack

2 : 5

2×3 : 5×3

6 : 15

niamah gets 6 pencils

jack gets 15 pencils

*6+15 = 21

Answer:

Step-by-step explanation:

If the ratio of Niamah to Jack is 2:5, that means that for every 2 pencils that N gets, J gets 5. If there are a total of 21 pencils, then

2x + 5x = 21 and

7x = 21 so

x = 3.

That means that N gets 2(3) which is 6, and J gets 5(3) which is 15. Notice that 6:15 is the same ratio as 2:5 when it is reduced.

Answer:

1.13 cm

Answer: $2294 should be invested in the simple interest account while $4588 should be invested in the certificate of deposit.

Step-by-step explanation:

Let x represent the amount that he would deposit in the simple interest account.

Let y represent the amount that he would deposit in the certificate of deposit.

she will deposit twice as much in the certificate of deposit. It means that

y = 2x

Interest from the simple interest account would be 7%. This mean that the interest would be 7/100 × x = $0.07x

Interest from the certificate of deposit account would be 5%. This mean that the interest would be 5/100 × y = $0.05y.

The total interest from both accounts would be $390. It means that

0.07x + 0.05y = 390- - - - - - - - - - 1

Substituting y = 2x into equation 1, it becomes

0.07x + 0.05 × 2x = 390

0.07x + 0.1x = 390

0.17x = 390

x = 390/0.17 = $2294

y = 2x = 2 × 2294

y = 4588

Answer:

Step-by-step explanation:

1/2*1/2*1/2 = 1/8 cubic units

2/(1/8) = 16

Answer:

16

Step-by-step explanation:

[tex](\frac{1}{2})^3 = \frac{1^3}{2^3} = \frac{1}{8}\\\frac{2}{\frac{1}{8}} = 2 \cdot 8 = 16[/tex]

Answer:

a, b, and d.

Step-by-step explanation:

They have a common angle = 25 deg.

The pair of sides created that common angle share the same ratio = 1/2

(6/12 = 3/6 = 8/16 = 1/2)

For this function, x can be any real value

Answer: [tex]-1\frac{1}{5}[/tex]

Step-by-step explanation:

[tex]2(P +1) + 3(P + 2 ) > 2[/tex]

Distribute 2 and 3

[tex]2P+2+3P+6>2[/tex]

Combine like terms;

[tex]5P+8>2[/tex]

Subtract 8

[tex]5P>2-8[/tex]

[tex]5P>-6[/tex]

Divide by 5

[tex]P>-\frac{6}{5}[/tex]

Convert to a mixed number by dividing. However, when we have the numerator greater than the denominator, we must find a way to make the numerator lower. We can achieve this by separating it into 2 fractions.

[tex]-\frac{6}{5}=-\frac{5}{5}-\frac{1}{5}[/tex]

When we do this, we can see that 5/5 = 1

[tex]-1-\frac{1}{5}=-1\frac{1}{5}[/tex]

What we do is to divide 1500 by 4 = $1500/4 = $375

Answer:375

Step-by-step explanation:

1500/4=375

Answer: x = 4

Step-by-step explanation:

You basically want to solve for the angle A. Do arcsin of 1/3, which is approximately 19.47 degrees. In this triangle, we are missing the adjacent and opposite, but we do have the angle luckily. Lets use SOH-CAH-TOA.

[tex]sin(theta) = \frac{opposite}{hypotenuse}[/tex]

We can see here that doing sine will give us the length of the opposite

[tex]sin19.47 = \frac{x}{12}[/tex]. Do sine of 19.47, then multiply by 12. I got 4

Answer:

Step-by-step explanation:

If the sum of a pair of angles is 90, then they are complementary angles.

25 + 65 = 90

So, 25 and 65 are complementary angles

Answer:

25 and 65

Step-by-step explanation:

complementary angle= either of two angles whose sum is 90°

25 and 65, sum = 90°

31 and 71, sum = 102°

60 and 40, sum = 100°

145 and 35, sum = 180°

Answer:

290

Step-by-step explanation:

The reason this is the answer is because if you divide 100% by 20% it will give you 5% so then you have to multiply 58 times 20 which will give you 290.

Answer:

Distance between 2 stations= 8.94 miles

Step-by-step explanation:

The coordinates of Symphony Station is given by:

Symphony Station: (x₁ , y₁) : (1,2)

The coordinates of Elm station is given by:

Elm Station: (x₂ ,y₂) : (-3,-6)

We know that the distance formula can be used to find distance between these 2 points. Distance formula is given as

d= √((x₂ - x₁)² + (y₂ - y₁) ²)

Substitute values

d= √((-3 - 1)² + (-6 - 2) ²)

d= √((-4)²+(-8)²)

d= √(16+64)

d=√80

d= 8.94 miles

Answer:

x = -1 or x = -7

Step-by-step explanation:

y = (x + 4)^2 - 9​

To find x-intercept, set y = 0

=>  (x + 4)^2 - 9​ = 0

=>  ( x + 1)( x + 7) = 0

=> x = -1 or x = -7

To find the x intercepts, plug in y = 0 and solve for x

y = (x+4)^2 - 9

0 = (x+4)^2 - 9 ... replace y with 0

9 = (x+4)^2

(x+4)^2 = 9

x+4 = plus/minus sqrt(9)

x+4 = sqrt(9)  or   x+4 = -sqrt(9)

x+4 = 3   or   x+4 = -3

x = 3-4    or   x = -3-4

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

Checking each answer:

Plug x = -1 into the original equation. You should get y = 0 as a result

y = (x+4)^2 - 9

y = (-1+4)^2 - 9

y = (3)^2 - 9

y = 9-9

y = 0 .... so this confirms x = -1 as a solution

The same should apply for the other potential solution x = -7

y = (x+4)^2 - 9

y = (-7+4)^2 - 9

y = (-3)^2 - 9

y = 9-9

y = 0 .... this confirms x = -7 as well
