Sonia noticed that during the summer an apple tree in their garden grew from 180 cm to 207 cm. What was the percent increase in height of the tree?

Answer:

x = -2

Step-by-step explanation:

The formula for the axis of symmetry is;

x = -b/2a

In this case;

b = 4 , a = 1

Therefore;

x = -4/2(1)

  = -2

Thus; the axis of symmetry is x = -2

Answer:

x = -2 is the axis of symmetry.

Step-by-step explanation:

We have given the function:

f(x)=x²+4x-19

We have to find the axis of symmetry.

We know that the formula for axis of symmetry is:

x = -b /2a

In this equation, b = 4 , a = 1

Putting these values we get,

x = -4/2(1)

x = -4/2

x = -2

x = -2 is the axis of symmetry of this function.

you would take 264+77+150=491in2

The answer is 491in squared

Answer:

A point represents a place/location.

Step-by-step explanation:

A point is used to locate a place in a map. It has no length, width and height.

The point is an undefined term. We use the point as undefined term and using the point we define line, line segment, angle and so on.

So a pointed represented location in a xy-coordinate plane.

x = 5

y = -4

4x + y = 16

multiply 2nd equation by 2

4x + 6y = -4

subtract equations

0 -5y = 20

-5y = 20

y = 20 ÷ -5

y = -4

substitute y = -4 to find the value of x

4x + (-4) = 16

4x - 4 = 16

4x = 20

x = 5

Answer:

The answer is negative nine

Step-by-step explanation:

When it comes to x = ?, divide the ANSWER by the mulitplicand. Example, -4x = 36 can be translated to 36 = -4 TIMES X, which here you have to use your head. Negatives cancel each other and the answer is positive, therefore -4 * -9 = 36.

Answer:

The value of b is, 8

Step-by-step explanation:

To determine the value of b:

Given:

[tex](152)_b = 0x6A[/tex]               ....[1]

Since, 0x6A represents the hexadecimal form.

To convert this hexadecimal form into decimal form:

[tex](6A)_{16}= (6 \times 16^1)+(A \times 16^0)=(6 \times 16)+(10 \times 1) =96+10 = 106[/tex]

⇒[tex]0x6A=106[/tex](decimal form)

Now we have to convert this decimal form into octal

8  |  106

8   |  13   | 2

    |   1    |  5

        1

Then, the octal form we get, [tex](152)_8[/tex]

Substitute this in [1] we have;

[tex](152)_b = (152)_8[/tex]

On comparing both sides we have;

b = 8

Therefore, the value of b is, 8

To evaluate the expression (6^7)(3^3)/(6^6)(3^4), simplify each term, resulting in 6^10 / 6^10, which equals 1.

To evaluate the expression (6^7)(3^3)/(6^6)(3^4), we can simplify each term first. The numerator can be simplified as (6^7)(3^3) = 6^(7+3) = 6^10. The denominator can be simplified as (6^6)(3^4) = 6^(6+4) = 6^10. Therefore, the expression simplifies to 6^10 / 6^10, which is equal to 1. So the value of the expression is 1.

I think it's 75 if wanting to add up to 180

Answer:

B

Step-by-step explanation:

30 ft = 360 in

8 ft = 64 in

360 in - 64 in = 296 in

296 / 8 = 33

It will take approximately 32.84 years for the tree to reach a height of 30 feet.

To determine the number of years it will take for the tree to reach a height of 30 feet, let's break down the growth process step by step.

Initially, the tree is 8 feet tall.

The tree grows 8 inches (0.67 feet) each year.

Let's assume it takes "x" years for the tree to reach a height of 30 feet.

So, the height of the tree after "x" years can be represented by the following equation:

Height after x years = Initial height + (Growth rate * x)

In this case, the initial height is 8 feet, and the growth rate is 0.67 feet (8 inches).

Height after x years = 8 + (0.67 * x)

Now, we need to solve for "x" when the height reaches 30 feet:

30 = 8 + (0.67 * x)

Subtract 8 from both sides of the equation:

22 = 0.67 * x

To isolate "x," divide both sides by 0.67:

x = 22 / 0.67

Now, calculate "x":

x ≈ 32.84 years

So, the Answer: B. 33 years

Final answer:

To convert liters to milliliters, multiply the number of liters by 1000. Therefore, 627 liters is equal to 627,000 milliliters.

Explanation:

To correctly complete the statement 627 L = ? mL, we need to convert liters to milliliters. Since there are 1000 milliliters (mL) in 1 liter, we multiply the number of liters by 1000 to find the number in milliliters.

Thus, the conversion is:

627 L × 1000 = 627,000 mL

Therefore, the statement 627 L = 627,000 mL is correct.

Answer:

First shape : 204cm^2

Second shape : 57in^2

Step-by-step explanation:

For the first shape :

The front and back triangles are 3 * 8 / 2 which gives us 12 on each side.

The side rectangles are 5 * 10 which is 50 on each side.

The bottom rectangle is 10 * 8 which is 80.

Add them all up and you get 204.

For the second shape :

The triangles are all congruent and the area is 3 * 8 / 2, so we get 12 on each side.

Then the bottom square is 3^2, which is 9.

Add them all up together and you get 57.

4.85×88=$426.80.

Answer:

TRANSFORMATION is a process by which one figure, expression, or function is converted into another one of similar value.

TRANSFORMATION is the induced or spontaneous change of one element into another by a nuclear process.

TRANSFORMATION is the genetic alteration of a cell by introduction of extraneous DNA, especially by a plasma.

Final answer:

In Biology, transformation involves the uptake of external DNA by a cell, leading to changes in its morphology and physiology. This process is commonly observed in bacteria, such as Streptococcus pneumoniae. It can result in the conversion of a non-virulent strain into a virulent one.

Explanation:

Transformation in Biology refers to the process in which external DNA is taken up by a cell, resulting in a change in its morphology and physiology. This genetic change through gene transfer is commonly observed in prokaryotes, such as bacteria. For example, in the case of Streptococcus pneumoniae, the bacterium that causes pneumonia, transformation can lead to the conversion of a non-virulent strain (rough) into a virulent one (smooth).

Answer:

x=6, y=63

Step-by-step explanation:

since both equal y, they equal each other-

8x+15=x+57

7x=42

x=6

then to solve for y-

y=(6)+57

y=63

The solution to the system of equations y = 8x + 15 and y = x + 57 is found via substitution, yielding x = 6 and y = 63 as the answer.

To solve the system of equations y = 8x + 15 and y = x + 57, we can use the method of substitution or elimination. However, since both equations are already solved for y ,, the most straightforward approach is substitution, implying that 8x + 15 = x + 57. To find the value of x, we subtract x from both sides and subtract 15 from both sides, yielding 7x = 42. Dividing both sides by 7, we find that x = 6. Substituting x = 6 into either of the original equations, for instance, y = 8(6) + 15, gives us y = 63. Therefore, the solution to the system of equations is x = 6 and y = 63.

Step-by-step explanation:

Answer:

y = 13x

Step-by-step explanation:

First we need to take the number miles the Johnson family drove and divide it to the number of gallons of gasoline used to find how many miles per gallon

Miles per gallon = 52/4

Miles per gallon = 13

Now that we know how many miles per gallon, let's make an equation to find how much they can travel on a full tank of 15 gallons.

Let y = number of miles traveled

Let x = number of gallons

y = 13x

Now let's see how much they can travel in 15 gallons.

y = 13x

y = 13(15)

y = 195 miles

So the Johnson family can drive 195 miles on a full tank of 15 gallons of gasoline.
