Hey there!

[tex]\large\boxed{25\%}[/tex]

Assuming that all the sections are the same size, there are four sections of equal size.

Blue would be one out of those four sections, so the probability is 1/4. In decimal form this is .25, and as a percent this is 25%.

Hope this helps!

The theoretical probability of landing on blue on a single spin of a spinner with 1 purple, 1 blue , 1 red , and 1 orange section is 1/4.

The theoretical probability of landing on blue on a single spin of a spinner with 1 purple, 1 blue, 1 red, and 1 orange section is 1/4 or 25%.

Total = 1+1+1+1 = 4

Number of blue =1

Therefore, probability =1/4

Length of the rectangle is 8m and width is 6m

Step-by-step explanation:

48 = x (x - 2)

48 = x² - 2x

x² - 2x - 48 = 0

x² - 8x + 6x - 48 = 0

x(x - 8) + 6(x - 8) = 0

(x + 6)(x - 8) = 0

x = -6, 8 (neglecting the negative value)

∴ Length of the rectangle = 8m

∴ Width of the rectangle = 8 - 2 = 6m

[tex]a_{n+1}[/tex] = [tex]a_{n}[/tex] - 7

Step-by-step explanation:

Note the common difference d between consecutive terms in the sequence, that is

d = - 35 - (- 28) = - 42 - (- 35) = - 49 - (- 42) = - 7

Thus to obtain a term in the sequence subtract 7 from the previous term

Elle experienced a 22.22% decrease in earnings from babysitting, from $45 to $35. This is calculated by finding the difference between the two amounts, dividing by the original amount, and then multiplying by 100 to convert to a percentage.

Elle's decrease in earnings can be calculated using the formula for calculating the percentage decrease, which is [(Original value - New value)/(Original value)] * 100.

In Elle's case, the original value is $45 (the amount she earned last month), and the new value is $35 (the amount she earned this month). So, follow the formula:

So, Elle experienced a 22.22% decrease in her earnings from babysitting.

Step-by-step explanation:

Step 1:  Distribute

7 (5x +  10) - 10x

35x + 70 - 10x

Answer:  25x + 70

In isosceles triangle ABC with AB=AC=4, and AH=3HC, the length of BC is [tex]\( \frac{4\sqrt{5}}{5} \)[/tex] units, determined using the Pythagorean Theorem and the given relationship between AH and HC.

In isosceles triangle ABC, let BH be the altitude from B to side AC. Given AB = AC = 4 and AH = [tex]3 \cdot[/tex] HC, we can use the Pythagorean Theorem in right triangle ABH:

[tex]\[ BH^2 + AH^2 = AB^2 \][/tex]

Substitute the given values:

[tex]\[ BH^2 + (3HC)^2 = 4^2 \][/tex]

Simplify:

[tex]\[ BH^2 + 9HC^2 = 16 \][/tex]

Since BH = HC in an isosceles triangle, substitute BH with HC:

[tex]\[ HC^2 + 9HC^2 = 16 \][/tex]

Combine like terms:

[tex]\[ 10HC^2 = 16 \][/tex]

Solve for HC :

[tex]\[ HC^2 = \frac{8}{5} \][/tex]

Now, use the Pythagorean Theorem in right triangle BHC:

[tex]\[ BC^2 = BH^2 + HC^2 \][/tex]

Substitute the known values:

[tex]\[ BC^2 = HC^2 + HC^2 \]\[ BC^2 = 2HC^2 \]\[ BC^2 = 2 \cdot \frac{8}{5} \]\[ BC^2 = \frac{16}{5} \][/tex]

Therefore, BC is the square root of [tex]\( \frac{16}{5} \)[/tex], which simplifies to [tex]\( \frac{4}{\sqrt{5}} \)[/tex] or [tex]\( \frac{4\sqrt{5}}{5} \)[/tex].

The length of BC in an isosceles triangle with sides AB=AC=4 and altitude BH, where AH=3(HC), is 2√2 units.

To determine the length of BC in an isosceles triangle ABC with sides AB=AC=4 and altitude BH, where AH=3(HC), we can use the properties of similar triangles and the Pythagorean theorem.

Since the triangle is isosceles, the altitude BH will bisect the base AC at H, creating two right triangles ABH and CBH. We know that AH=3(HC), which can be expressed as AH=3x and HC=x for some value x. Therefore, AC = AH + HC = 3x + x = 4x.

Using the Pythagorean theorem (a² + b² = c²), in triangle ABH, we get:

And in triangle HBC, we have:

Since we want to find BC, we first solve for BH from the first right triangle:

Substitute BH² into the second equation:

To find x, we use AC = 4x = 4, thus x = 1. Substituting x into the equation for BC, we get:

1. Recall the vertical line equation.

2. Plug in the x that we know.

3. Write down the final equation

Step-by-step explanation:

After the translation, rotation and reflection position of the image may differ but the side lengths, angle, orientation remains the same, so that the congruence is maintained, but in dilation the size of the image may get enlarged or reduced, so that congruence is not there.

Parallelograms are congruent when

Reflect across the y- axis and then translate 1 unit left.

Reflect across the y- axis then rotate 45° counterclockwise.

Translate 4 units up then rotate 180° counterclockwise

Parallelograms are non-congruent when

Translate 5 units right then dilate by a factor of 2

Rotate 90° clockwise then dilate by a factor of 6

Dilate by a factor of 3 then reflect across the x- axis

[tex]\large \boxed{\text{D. 126.2 cm}^{2}}[/tex]

Step-by-step explanation:

The area left over for scrap is the area of the circle minus the area of the hexagon.

1. Area of circle

The formula for the area of a circle is

A = πr²

A = π(6)² =  36π = 113.1 in²

2. Area of hexagon

A hexagon consists of six equilateral triangles, each of side a, and we can divide each of them into two right triangles.

So, we can calculate the area of one right triangle and multiply by 12.

The formula for the area of one triangle is

A = ½bh

(a) Height of a small triangle

Per the Pythagorean Theorem,

[tex]\begin{array}{rcr}h^{2} + 3^{2} & = & 6^{2}\\h^{2} + 9 & = & 36\\h^{2} & = & 27\\& = & 3\sqrt{3}\\\end{array}\\[/tex]

(b) Area of a small triangle

A = ½ bh = ½ × 3 × 3√3 = 4.5√3 in²

(c) Area of the hexagon

The hexagon contains 12 small triangles.

A = 12 × 4.5√ 3 = 54√3 ≈ 93.53 in²

3. Area of scrap

A ≈ 113.1 in² - 93.53 in² = 19.6 in²

[tex]A = \text{19.6 in}^{2} \times \left(\dfrac{\text{2.54 cm}}{\text{1 in}}\right )^{2} = \text{126.2 cm}^{2}\\\\\text{The area of the scrap is $\large \boxed{\textbf{126.2 cm}^{\mathbf{2}}}$}[/tex]

Answer:

(c)t=p+5

Step-by-step explanation:

total price= item price + gift wrapping cost (given)

gift wrapping cost is constant/unchanged= 5

total price= t

item price=p

therefore by derivation t=p+5 (option c)

Final answer:

The correct equation to represent the store's $5 gift wrapping fee added to the price of an item is C. t = p + 5, where p is the price of the item and t is the total cost with gift wrapping.

Explanation:

The question is asking to find an equation that shows the relationship between the price of an item, represented by p, and its total cost with gift wrapping, represented by t. Given that the store adds a $5 fee for gift wrapping, the correct equation needs to include the original price of the item and the additional gift wrapping fee. Therefore, the total cost t is equal to the price of the item p plus the $5 wrapping fee.

The correct equation representing this situation is C. t = p + 5.

This is because when you start with the initial price of an item p and add a fixed gift wrapping fee of $5, you get the total cost t. It is the sum of the two values: the price of the item plus the additional fixed fee for gift wrapping.

-14>-1 2/3

Step-by-step explanation:

Answer:

-14>-1 2/3

Step-by-step explanation:

The solution to the system of equations is (7, 13/3).

We have Equations,

y= 1/3x + 2,

y= 4/3 x - 5

Solving above two equations we get

1/3 x + 2 = 4/ 3 x - 5

1/3 x - 4/3 x = -5 - 2

-3/3 x = -7

-x = -7

x = 7

and, y = 4/3(7) - 5 = 28/3-5 = 13/3

Thus, the solution of equation is (7, 13/3).

84% probability of a meerkat living less than 14.6.

A similar problem is given at https://brainly.com/question/13503878

To estimate the probability of a meerkat living less than 14.6 years, we can use the empirical rule which states that approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.

To estimate the probability of a meerkat living less than 14.6 years, we can use the empirical rule which states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations.

Given that the average lifespan is 13.1 years and the standard deviation is 1.5 years, we can calculate the z-score for 14.6 years using the formula:

z = (x - μ) / σ

where x is the value we want to find the probability for (14.6 years), μ is the mean (13.1 years), and σ is the standard deviation (1.5 years).

Substituting the values, we get:

z = (14.6 - 13.1) / 1.5 = 1.0

Now we can look up the probability corresponding to a z-score of 1.0 in a standard normal distribution table, which is approximately 0.8413. This means that the probability of a meerkat living less than 14.6 years is about 0.8413 or 84.13%.
