I don’t even know how to answer this lol it’s too early for me. So confused plz help

The gardener's expression correctly calculates the area of the entire garden after extension, not just the extension itself. The error was in misinterpreting the question and focusing solely on the extension, leading to the incorrect answer of 13 square feet.

Expanding the expression: 6(x + 7) = 6x + 42. This represents the total area of the garden after extending its length by 7 feet.

Error analysis: The gardener likely assumed they needed to calculate the area added by the extension. This could be due to:

Misunderstanding the question and focusing on the 7-foot extension instead of the total area change.

Mistakenly interpreting "area of the extension" as the area of the rectangle formed only by the additional 7-foot length and the original width.

Therefore, while the expression itself is correct, the gardener misinterpreted the question and made an error in interpreting what "area of the extension" referred to.

r=0.2

Step-by-step explanation:

Given the quantities x and y

[tex]\left|\begin{array}{c|c}x&y\\---&---\\8&1.6\\15&3\\2&4.4\end{array}\right|[/tex]

When x=8, y=1.6

On Substitution into y=rx

1.6=8r

r=1.6/8=0.2

When x=15, y=3

On Substitution into y=rx

3=15r

r=3/15=0.2

When x=2, y=0.4

On Substitution into y=rx

0.4=2r

r=0.4/2=0.2

Therefore, the constant of proportionality, r=0.2

NOTE: One set of values is enough to determine this. Others are done for verification.

Answer:

width: 2

length: 10

Step-by-step explanation:

L = 3W + 4

A = LW = (3W + 4) x W

  = 3w² +4w

3w² + 4w = 20

3w² + 4w -20 = 0

(w - 2) (3w + 10) = 0

w = 2 or w = - 10/3     (width is positive)  ∴ width = 2

length = 3 x 2 + 4 = 10

The scale factor from figure a to figure b would be 1/16 i believe.

Correct me if im wrong

The scale factor of figure A to figure B is 5/9.

In the given figure, A and B are similar triangles.

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

The basic formula to find the scale factor of a figure is expressed as,

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Here, 20/36

= 5/9

= 14/25.2

= 2/3.6

= 5/9

Hence, the scale factor of figure A to figure B is 5/9.

Step-by-step explanation:

the number that comes after the hundreth place(4) is less than 5 so you keep all of the other numbers the same

Answer:

460 ft

Step-by-step explanation:

2 more than triple the number can be expressed as 3x + 2. We want this expression to equal 10, so we can set up the equation as 3x + 2 = 10.

To solve the equation, '2 more than triple a number is 10', we can first translate the sentence into an equation.

Let's assume the number is represented by x.

Triple the number would be 3x. And 2 more than triple the number can be expressed as 3x + 2.

We want this expression to equal 10, so we can set up the equation as follows:

3x + 2 = 10

Now, we can solve for x by isolating it on one side of the equation.

Subtracting 2 from both sides, we get:

3x = 8

Finally, divide both sides by 3 to solve for x:

x = 8/3

Comparing a hatchling turtle's shell of 1-inch diameter to a 4-inch diameter shell reveals that the volume increases by a factor of about 64, while the surface area only increases by about 16. This difference is due to the way volume and surface area are calculated, with the radius being cubed in the volume formula and squared in the surface area formula.

The volume of a sphere (like the turtle's shell) is given by the formula: V = (4/3) * π * r³, and the surface area by A = 4 * π * r², where r is its radius. If a hatchling turtle's shell has a 1-inch diameter, it has a radius of 0.5-inches. If as the turtle grows, its diameter expands to 4-inches, then the radius will be 2-inches. As the radius in each formula is cubed in the volume formula and squared in the surface area formula, the volume will increase far more rapidly than the surface area.

For the smaller turtle, V = (4/3)*π*(0.5)³ = 0.52 cubic inches and A = 4*π*(0.5)² = 3.14 square inches. For the larger turtle, V = (4/3)*π*(2)³ = 33.51 cubic inches and A = 4*π*(2)² = 50.27 square inches. Comparing, the volume increases by a factor of 64 (33.51/0.52) whereas the surface area increases by a factor of roughly 16 (50.27/3.14). This shows that although the turtle's shell maintains the same shape as it grows, the volume increases significantly more than the surface area.

Final answer:

The Great Wall of China was approximately 3,000 miles long.

Explanation:

The Great Wall of China was 10,000 li long. In this case, li is a unit of measure. We are told that 2 li is approximately equal to 0.6 miles. To find how many miles the Great Wall is, we can set up a proportion:

2 li = 0.6 miles
10,000 li = x miles

To solve for x, we can cross multiply and divide:

10,000 li * 0.6 miles = 2 li * x miles
6,000 miles = 2x
x = 6,000 / 2
x = 3,000 miles

Therefore, Shih Huangdi's Great Wall of China was approximately 3,000 miles long.

Answer:

C= 2M + 10

Step-by-step explanation:

In this equation, we will calculate the total cost. So, we'll start off with "C =" Then, we know tat the charge is $2 per mile so we'll add it and make C = 2M. Then, it states that the flat fee is 10 dollars which makes the equation

C = 2M +10.

Answer:

C = 2M + 10

Step-by-step explanation:

To write this equation, we will use slope-intercept form: y = mx+b

In this problem, C is y and M is x, so: C = mM + b

m is the slope, or the rate of change, and b is the y-intercept.

The y-intercept in this problem is the $10 flat fee.

The rate of change is the additional $2 per mile.

Let's input these values into our equation:

C = 2M + 10

(x - 1) and (x + 4)

Step-by-step explanation:

Given the zeros of a polynomial, say x = a, x = b then the factors are

(x - a), (x - b) and the polynomial is the product of the factors, that is

f(x) = (x - a)(x - b)

Here the zeros are x = 1 and x = - 4, thus the factors are

(x - 1) and (x - (- 4)), that is (x - 1) and (x + 4)

The volume of the part of silo filled with corn is 3391.2 cubic foot.

Step-by-step explanation:

Diameter of the silo = 12ft.

Radius = 6 ft.

Height = 60ft.

Volume = π(r x r) h

= (3.14) (36) 60

= 6782.4 cubic foot

The corn is 50% filled. So,

Volume of corn filled = (50/100) (6782.4)

= 3391.2 cubic foot

The volume of the part of silo filled with corn is 3391.2 cubic foot.

a) [tex]X<67.1[/tex]

b) 0.1539

c) 0.1539

d) 0.6922

Step-by-step explanation:

a)

In this problem, the score on the exam is normally distributed with the following parameters:

[tex]\mu=78.1[/tex] (mean)

[tex]\sigma = 10.8[/tex] (standard deviation)

We call X the name of the variable (the score obtained in the exam).

Therefore, the event "a student obtains a score less than 67.1) means that the variable X has a value less than 67.1. Mathematically, this means that we are asking for:

[tex]X<67.1[/tex]

And the probability for this to occur can be written as:

[tex]p(X<67.1)[/tex]

b)

To find the probability of X to be less than 67.1, we have to calculate the area under the standardized normal distribution (so, with mean 0 and standard deviation 1) between [tex]z=-\infty[/tex] and [tex]z=Z[/tex], where Z is the z-score corresponding to X = 67.1 on the s tandardized normal distribution.

The z-score corresponding to 67.1 is:

[tex]Z=\frac{67.1-\mu}{\sigma}=\frac{67.1-78.1}{10.8}=-1.02[/tex]

Therefore, the probability that X < 67.1 is equal to the probability that z < -1.02 on the standardized normal distribution:

[tex]p(X<67.1)=p(z<-1.02)[/tex]

And by looking at the z-score tables, we find that this probability is:

[tex]p(z<-1.02)=0.1539[/tex]

And so,

[tex]p(X<67.1)=0.1539[/tex]

c)

Here we want to find the probability that a randomly chosen score is greater than 89.1, so

[tex]p(X>89.1)[/tex]

First of all, we have to calculate the z-score corresponding to this value of X, which is:

[tex]Z=\frac{89.1-\mu}{\sigma}=\frac{89.1-78.1}{10.8}=1.02[/tex]

Then we notice that the z-score tables give only the area on the left of the values on the left of the mean (0), so we have to use the following symmetry property:

[tex]p(z>1.02) =p(z<-1.02)[/tex]

Because the normal distribution is symmetric.

But from part b) we know that

[tex]p(z<-1.02)=0.1539[/tex]

Therefore:

[tex]p(X>89.1)=p(z>1.02)=0.1539[/tex]

d)

Here we want to find the probability that the randomly chosen score is between 67.1 and 89.1, which can be written as

[tex]p(67.1<X<89.1)[/tex]

Or also as

[tex]p(67.1<X<89.1)=1-p(X<67.1)-p(X>89.1)[/tex]

Since the overall probability under the whole distribution must be 1.

From part b) and c) we know that:

[tex]p(X<67.1)=0.1539[/tex]

[tex]p(X>89.1)=0.1539[/tex]

Therefore, here we find immediately than:

[tex]p(67.1<X<89.1)=1-0.1539-0.1539=0.6922[/tex]

Answer:

16 cm,7cm, start root 12.

Answer:

? = 24, AB = 8.66 (square root of 75, 5 times the square root of 3)

Step-by-step explanation:

Since the whole length equals 27, we can subtract 3 to get 24. The proportion is a setup for geometric mean. This means cross-multiplying. X x X = X^2, 3 x 24 = 72. Square root both sides to get X by itself. [tex]3\sqrt{8} \\[/tex]. Use Pythagoreans to solve the rest. You are left with the square root of 75, or 5 times the square root of 3.
