Answer:

Tree C

Step-by-step explanation:

each of the charts/tables/paragraphs are talking about a different tree.

Tree A started with 5 inches, as it says.

Tree B started with 3 inches, as you can see under the 0 months.

Tree C, at the month 0 mark, has a height of 10 inches, so it started with 10.

10>5 and 10>4, so Tree C is the biggest

Answer:

44

Step-by-step explanation:

substitute the 7 into the equation for x

f(x) = [tex]x^{2}[/tex] - 5

f(7)  = [tex]7^{2}[/tex] - 5

f(7) = 49 - 5

f(7) = 44

Answer:

f(7) = 44

Step-by-step explanation:

To evaluate the function f(x)=x^2-5 at x = 7, replace each instance of 'x' in this function by 7:

f(7) = 7^2 - 5 = 49 - 5 = 44

So:  f(7) = 44

Answer:

The diagonal is 6.7082 ≈ 6.71

Step-by-step explanation:

Let the diagonal be x :

To find the diagonal of a 3 by 6 rectangle

We can use the Pythagorean Theorem:

[tex]x^{2} = 3^{2} + 6^{2}[/tex]

⇒ [tex]x^{2} = 9 +36[/tex]

⇒ [tex]x^{2} = 45[/tex]

⇒ [tex]x=\sqrt{45}[/tex]

∴ [tex]x =6.7082[/tex] ≈ [tex]6.71[/tex] (corrected to 2 d.p.)

Answer:

Part A

x + y ≤ 460...(1)

2.5·x + 1.25·y ≥ 600...(2)

Part B

The number of bottles of water the student must sell ≥ 192 bottles of water

Step-by-step explanation:

The given parameters are;

The selling price of each can of lemonade = $2.50

The selling price of each bottle of water = $1.25

The amount of money the club needs to raise = $600

The maximum number of cans and bottles the students can accept = 460

Part A

Let 'x' represent the number of cans of lemonade the students accept, and let 'y' represent the number of bottles the student accept, the system of inequalities that can be used to represent the situation can be presented as follows;

x + y ≤ 460...(1)

2.5·x + 1.25·y ≥ 600...(2)

Part B

The number of cans of lemonade the club sells, x = 144

The number of bottles of water the student must sell to cover the cost of costumes, 'y', is given from the second inequality as follows;

2.5 × 144 + 1.25·y ≥ 600

1.25·y ≥ 600 - 2.5 × 144 = 240

1.25·y ≥ 240

y ≥ 240/1.25 = 192

y ≥ 192

The number of bottles of water the student must sell = 192 bottles of water

Answer:

35

Step-by-step explanation:

Perimeter of LMK = 14 + 11 + 17

Perimeter of LMK = 42

Perimeter GHJ/ Perimeter LMK = 5/6

Perimeter GHJ / 42 = 5/ 6                      Cross Multiply

6*Perimeter GHJ = 42 * 5

6*Perimeter GHJ = 210                           Divide by 6

Perimeter GHJ = 210/6

Perimeter GHJ = 35

Step-by-step explanation:

Answer:

This is the answer48 cm²

Answer:

A = 44 cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

We require to find the missing segment of b₁

Using the tangent ratio in the right triangle

tan45° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{4}{adjacent}[/tex] = 1 , so

adjacent = 4

Then

b₁ = 4 + 8 + 2 = 14 , b₂ = 8 and h = 4 , then

A = [tex]\frac{1}{2}[/tex] × 4 × (14 + 8) = 2 × 22 = 44 cm²

Answer:  Most 1997 pennies in circulated condition are only worth their face value of $0.01. These coins can only sell for a premium in uncirculated condition. The 1997 penny with no mint mark and the 1997 D penny are each worth around $0.30 in uncirculated condition with an MS 65 grade. unless you have an very rare 1997 penny thats then when it would become worth 20$

Answer:

  (a) The function that is represented by the equation y=-10x+6 has a steeper slope and a greater y-intercept

Step-by-step explanation:

If we take the "steepness" of the slope to be the absolute value of the slope, then the line y=-10x +6 has a slope with a steepness of 10.

The line y -36 - 8(x -4) has a slope with a steepness of 8, so the first line is steeper.

The line y=-10x+6 has a y-intercept of 6. The line y-36 =8(x -4) has a y-intercept of 4, so the first line has a higher y-intercept.

The appropriate description of the two lines is ...

Answer:

Q19 - x = 7

Q20 - x = 24

Step-by-step explanation:

Q19.

75 + x + 8 = 90°

83 + x = 90°

x = 90 - 83

x = 7

{CHECK: 75 + 7 + 8 = 90°}

Q20.

3x - 6 + x = 90°

4x - 6 = 90°

4x = 96

x = 96 / 4

x = 24

{CHECK: 3(24) - 6 + 24 = 90°}

hope this helps...

Step-by-step explanation:

the answer is in the above image

please give me brainliest

Answer:

Width = w

Length = 4w + 6

Area = 130 in2

Area = W X L = 130

So, w X (4w + 6) = 130

4w2 + 6w = 130  by distributing

-130           -130

4w2 + 6w - 130 = 0

Step-by-step explanation:

Answer:

Area = 6L² - 4L

Step-by-step explanation:

Let length be L

Given Width, w is 4 less than 6 times length :

That is ,

6 times length = 6 L

4 less than 6 times length means = 6L - 4

Therefore Length  =  L

               Width = 6L - 4

Area = Length x Width

       = L x ( 6L - 4)

       = 6L² - 4L

Answer:

Step-by-step explanation:

We need a system of equations to help us solve this. One of the equations in the system is about the number of cultures bought, and the other one is about the money spent on the cultures. They are 2 very different things!

The #'s equation says that the number of cultures (c) plus the number of vials (v) totaled 57. The equation that puts that together is

c + v = 57

Now for the money part. Each culture costs $8, so the expression for that is 8c; each vial costs $1, so the expression for that is 1v; we know the amount of money spent in total was $106. The equation for that is

8c + 1v = 106

There's our system. 2 unknowns need 2 equations. Go back to the first one and solve it for either c or v. I'll solve for c, just because:

c = 57 - v. Now sub that value for c into the money equation:

8(57 - v) + v = 106 and

456 - 8v + v = 106 and

-7v = -350 so

v = 50. There are 50 vials of fruit flies. To find c, plug that into the first equation:

c + 50 = 57 so

c = 7.

Answer:

Answer:

x = 10 / 7 (or) 1.43 <rounded to 2 decimal place>

y = - 54 / 7 (or) -7.71 <rounded to 2 decimal place>

Step-by-step explanation:

Another way to rewrite (5x-3y, 3x-y) = (16, 12),

5x - 3y = 16 -- (1)

3x - y = 12 -- (2)

Rewriting (1), y = -5/3x - 16/3 -- (1)'

Substituting (1)' into (2),

3x + 5/3x + 16/3 = 12

14/3x = 20/3

x = 10 / 7 -- (3)

Substituting (3) into (2),

3(10/7) - y = 12

30/7 - y = 12

-y = 54 / 7

y = - 54/7-- (4)

Therefore,

x = 10 / 7 (or) 1.43 <rounded to 2 decimal place>

y = - 54 / 7 (or) -7.71 <rounded to 2 decimal place>

Answer:

The answer is height=7

Step-by-step explanation:

Formula needed for this problem is Area= Base times Height divided by 2.

The first step to solving this problem is to do the exact opposite of this formula. since we already know the area we will multiply that by two to get 84. Then 84 will be divided by 12 to get 7. If anything confuses you on this problem please feel free to ask!

Answer:

B. -9

Step-by-step explanation:

X² + 14x +45=0

(x+9)(x+5)=0

x = -9 or x = -5

x = -9 is the answer

Answer:

B. -9

Step-by-step explanation:

X^2 + 14x +45=0

Factor

What two numbers multiply to 45 and add to 14

5*9 = 45

5+9 = 14

(x+5)(x+9) = 0

Using the zero product property

x+5 =0  x+9=0

x+5-5 =0-5    x+9-9 = 0-9

x = -5            x=-9
