Answer:378

Step-by-step explanation:32 times 4=178 +250=378

Alice Jones's gross pay for the week is the sum of her hourly earnings ($128 from working 32 hours at $4.00 per hour) and her tips ($250), totalling $378.

To calculate Alice Jones's gross pay, we need to consider both her hourly wage and her tips. Alice worked 32 hours this week and was paid $4.00 per hour. This means her earnings from her hourly wage are:

32 hours times $4.00/hour = $128

Alice also earned $250 in tips. To find her gross pay for the week, we add her hourly earnings to her tips:

$128 + $250 = $378

Therefore, Alice's gross pay for the week is $378.

Answer:

49998 pennies left

Step-by-step explanation:

50000 - 2 = 49998

Answer:

50000-2=49998

Step-by-step explanation:

x = dimes

y = quarters

We also know:

Dimes: 0.10

Quarters: 0.25

100 = x + y

So, 0.10x + 0.25y = 100

And, y = 100 - x

Let’s use substitution:

0.10x + 0.25( 100 - x ) = 100

= 0.10x + 25 - 0.25x = 100

= 25 - 100 = 0.25x - 0.10x

= (-75) = 0.15x

x = (-75) divide by 0.15

x = (-500)

Answer:

The factored form of the polynomial is 11*(x+2)*(x-5/11). The root found was r = -2

Step-by-step explanation:

If you take a positive value of x, you will most likely obtain positive results, since 11x² + 17x ≥ 11 + 17 = 28 for x ≥1, which means that 11x²+17x-10 ≥ 28-10 = 18 > 0.

Therefore, we prove with negative values.

Therefore, -2 is a root. We can find the other knowing that

p(x) = 11*(x-r₁)*(x-r₂) = 11*(x-(-2)) * (x-r₂) = 11*(x+2)*(x-r₂)

The independent term is 11*2*(-r₂) = -22r₂ = -10

thus, r₂ = -10/-22 = 5/11.

Therefore, p(x) = 11*(x+2)*(x-5/11)

To write 11x2+17x−10 in factored form we find two numbers whose sum is 17 and product is -110. The correct pair is 2 and -55 which leads to the factored form (11x - 55)(x + 2).

The question involves factoring a quadratic expression, 11x2+17x−10. To re-write this expression in factored form, one needs to find two numbers, such that their sum equals to the coefficient of x, 17, and their product equals to the product of the coefficient of x² and the constant term (11*(-10)=-110). Diego started by listing all pairs of factors of the constant term, -10. The correct pair here, considering the product and the sum, are 2 and -55, because 2*(-55)=-110 and 2+(-55)=17. Therefore, our factored form will be: (11x - 55)(x + 2).

Answer:

(3n + 4) (n-2)

Step-by-step explanation:

Are you asking to factor this 3n^2 - 2n -8 ?

If so the best way to do this problem  is with the X method.

                                     top:    3*(-8)

    left:  factor of 3*-8                             right:  factor of 3*-8

                                   bottom:  -2

try the factors  4 and -6  because   4*-6 =  3 *-8 = -24

Because   notice that  4 + -6 = -2

so:

    3n^2 -2n - 8  can be rewritten as    3n^2  -6n + 4n  - 8

We should first use Distributive property to factor:  3n^2  -6n + 4n  - 8

3n^2  -6n + 4n  - 8  =   3n (n - 2)  +  4(n - 2)

Now we factor by grouping here :   (3n + 4) (n-2)  

I factored out the group  (n-2)

Therefore:  (3n + 4) (n-2) = 3n^2 -2n - 8

Answer:

The correct answer is 25.

Step-by-step explanation:

A cooking magazine shows a photo of a main dish on the front cover of 5 out of the 12 issues it publishes each year.

Number of publications by the magazine every year = 12.

Number of publications in 5 years = 12 × 5 = 60.

Out of these 12 magazines in a year, the photo of a main dish is on 5 magazines.

Therefore in 60 magazines, the photo of a main dish would be 5 × 5 = 25 magazines.

Thus in five years there would be 25 publications in which the front page will have a poster of a main dish.

Based on the number of times the photo appears per year, in 5 years it will appear 25 times.

Every year, the photo in question appears 5 out of 12 times.

If there were 5 years therefore, it would appear:

= Number of times per year x Number of years

= 5 x 5

= 25 times

In conclusion, the photo of a main dish will appear 25 times in 5 years.

Answer:

a. (√3)/2

b. 60 degrees.

Step-by-step explanation:

Please kindly check the attached files for explanation.

The sine of the angle is √3 / 2, and the measure of the angle is 60°.

Finding the Angle Between a Cable and the Ground

To determine the sine of the angle ( heta) between the cable and the ground, we need to use the horizontal and vertical forces exerted by the cable. We have a horizontal pull of 800 Newtons and a vertical pull of 800√3 Newtons.

First, we calculate the sine of the angle using the formula:

Sine ( heta) = Opposite / Hypotenuse

Here,
Opposite = Vertical Pull = 800√3 N
Hypotenuse = Resultant Force = √[(Horizontal Pull)^2 + (Vertical Pull)^2] = √[(800)^2 + (800√3)^2] = 1600 N

Thus,

Sine ( heta) = 800√3 / 1600 = √3 / 2

We know that the angle  heta with a sine value of √3 / 2 is 60 degrees (or  heta = 60°).

In conclusion, sine of the angle is √3 / 2, and the measure of the angle is 60°.

Final answer:

Three segments with lengths 4 cm, 6 cm, and 11 cm cannot form a triangle because the sum of the lengths of the two shorter sides is not greater than the length of the longest side, violating the Triangle Inequality Theorem.

Explanation:

To determine whether three segments with lengths 4 cm, 6 cm, and 11 cm can form a triangle, we must consider the Triangle Inequality Theorem. This theorem states that for any triangle, the sum of the lengths of any two sides must be greater than the length of the third side. If we attempt to apply this to the given lengths:

4 cm + 6 cm > 11 cm (False)

4 cm + 11 cm > 6 cm (True)

6 cm + 11 cm > 4 cm (True)

Since the sum of the lengths of the two shorter sides (4 cm + 6 cm) is not greater than the length of the longest side (11 cm), these three segments cannot form a triangle, whether it is an acute triangle, right triangle, or obtuse triangle.

If they were able to form a triangle, to classify the type of triangle, we would use the Converse of the Pythagorean Theorem. This theorem helps us understand if a triangle is acute, right, or obtuse:

In a right triangle, the square of the length of the longest side (hypotenuse) is equal to the sum of the squares of the lengths of the other two sides.

If the square of the longest side is greater than the sum of the squares of the other two sides, the triangle is obtuse.

If the square of the longest side is less than the sum of the squares of the other two sides, the triangle is acute.

However, since a triangle cannot be formed with these segments, we do not need to apply these rules here

Russia obtained [tex]\( 5\% \)[/tex]of the total gold medals for the top 8 countries.

Let's denote the total number of gold medals obtained by Russia as [tex]\( x \)[/tex]. Since we know Russia got 3 gold medals, we have [tex]\( x = 3 \)[/tex].

Now, let's denote the total number of gold medals obtained by the top 8 countries (including Russia) as T. We're told that the total number of gold medals obtained by all top 8 countries combined is 60. Since Russia got 3 gold medals, the gold medals obtained by the other top 7 countries is [tex]\( T - 3 \)[/tex].

So, the percentage of gold medals obtained by Russia can be calculated as:

Percentage of gold medals obtained by Russia = [tex]\frac{\text{Number of gold medals obtained by Russia}}{\text{Total number of gold medals obtained by the top 8 countries}} \times 100\%\][/tex]

Substituting the known values:

[tex]\[\text{Percentage of gold medals obtained by Russia} = \frac{3}{T} \times 100\%\][/tex]

We know that the total number of gold medals obtained by the top 8 countries is 60, so [tex]\( T = 60 \).[/tex] Substituting this into the equation:

[tex]\[\text{Percentage of gold medals obtained by Russia} = \frac{3}{60} \times 100\%\][/tex]

Solving this equation:

[tex]\[\text{Percentage of gold medals obtained by Russia} = \frac{1}{20} \times 100\% = 5\%\][/tex]

So, Russia obtained [tex]\( 5\% \)[/tex]of the total gold medals for the top 8 countries.

Answer:

get the brainliest duck

Step-by-step explanation:

The volume of the new building is 11,726,069,760 cubic inches, and its surface area is 51,555,840 square inches.

To find the volume and surface area of the new building, we first need to calculate the dimensions of the new building by scaling up the dimensions of the model by a factor of 144.

1. Dimensions of the new building:

  -[tex]Width: \(10 \times 144 = 1440\) inches[/tex]

  - [tex]Length: \(18 \times 144 = 2592\) inches[/tex]

  - [tex]Height: \(28 \times 144 = 4032\) inches[/tex]

2. Volume of the new building:

  The volume of a rectangular prism (building) is calculated by multiplying its length, width, and height.

[tex]\[Volume = \text{Length} \times \text{Width} \times \text{Height}\][/tex]

  Substituting the given dimensions:

 [tex]\[Volume = 2592 \times 1440 \times 4032\][/tex]

 [tex]\[Volume = 11,726,069,760 \text{ cubic inches}\][/tex]

3. Surface area of the new building:

  The surface area of a rectangular prism (building) is calculated by adding the areas of all six sides.

[tex]\[Surface\,Area = 2(\text{Length} \times \text{Width} + \text{Length} \times \text{Height} + \text{Width} \times \text{Height})\][/tex]

  Substituting the given dimensions:

[tex]\[Surface\,Area = 2(2592 \times 1440 + 2592 \times 4032 + 1440 \times 4032)\][/tex]

 [tex]\[Surface\,Area = 51,555,840 \text{ square inches}\][/tex]

So, when the new building is completed:

- The volume will be [tex]\(11,726,069,760 \text{ cubic inches}\).[/tex]

- The surface area will be [tex]\(51,555,840 \text{ square inches}\).[/tex]

Answer:

Step-by-step explanation:

-The diagrams can be said to be mathematically similar if the dimensions of their corresponding sides enlarge or reduce by the same factor.

-We therefore determine the enlargement factor for both the radius and height as below:

-Let k be the scale factor

[tex]k_r=\frac{R}{r}\\\\=\frac{3.64}{2.6}\\\\=1.4\\\\k_h=\frac{H}{h}\\\\=\frac{10.192}{8.32}\\\\=1.225\\\\k_r\neq k_h[/tex]

Hence, the cylinders are not mathematically similar since the enlargment factors for the radius and height are not equal.
