What is the value of x?

Answers

Answer 1
area of shaded region = area of outer circle - area of inner circle.

288pi  = pi * (2x)^2 - pi * 6^2

288  = 4x^2 - 36

the ratio of red circles to blue circles is 1:3 How many more red circles would need to be added to make the ratio of red to blue 3:1?

Answers

8 more red circles will be needed
The answer is 8 because since there are 3 blue circles, you would need to have 3 times as many red circles as there are blue. Therefore, you would need to balance the ratio from 3:1 to 9:3. These are equal, just simplified. So 8 would be your answer.

Luis skates 2/3 mile from his home to school. Isabella skates 2/4 mile to get to school. Who skates father?

Answers

In order to figure out whether Luis or Isabella skates farther to get to school, we have to create a common denominator between the two fractions that represent the distance that each person walks.

The least common denominator of 3 and 4 is 12.  This means that we have to change both fractions into equal fractions with denominators of 12.

To figure this out, we must set up a proportion.
2/3 = x/12
To solve this proportion, we must cross-multiply the fractions.  We get:
24 = 3x
If we divide both sides by the coefficient of x which is 3, to get the variable x alone, we get:
x = 8

Therefore, 2/3 = 8/12, so Luis skates 8/12 mile from his home to school.

If we do the same process for the 2/4 mile to get to school for Isabella, we get 6/12, because both fractions are equal to 1/2.

Therefore, we know that Luis skates 8/12 mile to school and Isabella skates 6/12 mile to get to school.  Because they have the same denominator, we can just compare the numerators.  We know that 8 is greater than 6, thus Luis skates farther to get to school.

Final answer:

Luis skates further to school than Isabella, as 2/3 mile is greater than Isabella's distance of 1/2 mile after simplification.

Explanation:

The question revolves around figuring out who skates further to school, Luis or Isabella. Luis skates 2/3 mile from his home to school whereas Isabella skates 2/4 mile (which can be simplified to 1/2 mile) to get to school. To determine who skates further, we look at the fraction representing the distance each person skates.

Luis's distance is 2/3 mile, and Isabella's distance, after simplification, is 1/2 mile. Since 2/3 is greater than 1/2, Luis skates further to get to school than Isabella.

Volume equals Length times Width times Height.
V=2.5*4*2.25
V=22.5
22.5 is already in decimal form, or if you'd rather have a mixed number, your answer is 22 [tex] \frac{1}{2} [/tex]

In general, a positive constant moves a function upwards and a negative value moves it downwards. Thus, g(x)=⌈x⌉+0.5 is 0.5 units above f(x)=⌈x⌉, as shown in attached picture.

To shift a function left, you add units to the independent variable.To shift it right, you subtract a constant from "x".

Step-by-step explanation:

Putri is searching for a secret cave that she knows is 3.72 kilometers from her home. Starting from her home, she walks 2.60 kilometers in a straight line before coming upon a large rock.
Climbing atop the rock, Putri spots the cave. She then turns 58 degrees to the right of her original path and walks to the cave. After exploring the cave, she looks back at the big rock and wonders how to get home.
Assuming Putri is facing the big rock, how many degrees to her left should she turn before walking home?

Answers

The Putri turned 36 degrees to her left should she turn before walking home if Putri is searching for a secret cave that she knows is 3.72 kilometers from her home. Starting from her home, she walks 2.60 kilometers in a straight line before coming upon a large rock.

What is the triangle?

The triangle can be defined as a three-sided polygon in geometry and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.

We have:

The total distance between cave to home AC = 3.72 km

The distance she walks AB = 2.60 km

The angle of turn = 58°

As we can see in the triangle ABC we can apply the sin law:

[tex]\rm \frac{AB}{sinx} = \frac{AC}{sin58\°}[/tex]

[tex]\rm \frac{2.6}{sinx} = \frac{3.72}{sin58\°}[/tex]

sinx = 0.5927

x = 36.35 ≈ 36°

Thus, the Putri turned 36 degrees to her left should she turn before walking home if Putri is searching for a secret cave that she knows is 3.72 kilometers from her home. Starting from her home, she walks 2.60 kilometers in a straight line before coming upon a large rock.

Putri should turn 122 degrees to her left when facing the big rock to head back to her home. This direction aligns her with the original path she took to reach the cave.

To determine the number of degrees to her left Putri should turn, we need to analyze her movements using the angles involved.

Putri starts by walking 2.60 kilometers in a straight line.She spots the cave after climbing the rock and turns 58 degrees to the right of her original path.This new path takes her directly to the cave, which is a straight-line distance of 3.72 kilometers from her home.

When Putri is in the cave facing the large rock, to get back to her home, she needs to turn in the opposite direction of her initial right turn:

Initially, she turned 58 degrees to the right.Facing the rock, she must turn 180 degrees - 58 degrees = 122 degrees to her left to be aligned with her starting path towards home.

Putri should turn 122 degrees to her left when facing the big rock to head back to her home.

Dominic is building a bench with a seat in the shape of a trapezoid. One base is 5 feet. The other base is 4 feet. The perpendicular distance between the bases is 2.5 feet. what is the area of the seat

Answers

By definition, the formula for finding the area of a trapezoid is
 A = [(b1 + b2) x h] / 2
 Where,
 b1: Base 1
 b2: Base 2
 h: height, or distance between bases.
 Substituting we have:
 A = ((5 + 4) * (2.5)) / 2
 A = 11.25 feet ^ 2

 Answer: 
 the area of the seat is:
 A = 11.25 feet ^ 2

The area of Dominic's trapezoid-shaped bench seat is 11.25 square feet. This is calculated using the trapezoid area formula with given bases of 5 and 4 feet and a height of 2.5 feet.

To find the area of the seat of Dominic's bench, which is in the shape of a trapezoid, we use the formula for the area of a trapezoid:

Area = 1/2 × (Base1 + Base2) × Height

In this case:

Base1 (b1) = 5 feetBase2 (b2) = 4 feetHeight (h) = 2.5 feet

Substitute these values into the formula:

Area = 1/2 × (5 + 4) × 2.5

Area = 1/2 × 9 × 2.5

Area = 4.5 × 2.5

Area = 11.25 square feet

Thus, the area of the trapezoid-shaped seat is 11.25 square feet.

Answers

Rewriting it as improper fractions if necessary:
25/6, 39/7

For the denominators (6, 7) the least common multiple (LCM) is 42.

Therefore, the least common denominator (LCD) is 42.

Rewriting the original as equivalent fractions with the LCD:
175/42, 234/42.


Here are the steps to follow:

Find the Least Common Multiple of the denominators (which is called the Least Common Denominator).

Change each fraction (using equivalent fractions) to make their denominators the same as the least common denominator

Then add (or subtract) the fractions, as we wish!

Hoped I helped!



The LCD of [tex]\( \frac{4}{6} \)[/tex] and [tex]\( \frac{5}{7} \)[/tex] is [tex]42[/tex]. This is because [tex]42[/tex] is the smallest number that both [tex]6[/tex] and [tex]7[/tex] divide into evenly, ensuring that [tex]\( \frac{25}{6} \)[/tex] and [tex]\( \frac{39}{7} \)[/tex] can be expressed with a common denominator of [tex]42.[/tex]

1. Convert [tex]\( 4 \frac{1}{6}[/tex]  to an improper fraction:

[tex]\[ 4 \frac{1}{6} = \frac{4 \times 6 + 1}{6} = \frac{24 + 1}{6} = \frac{25}{6} \][/tex]

2. Convert [tex]\( 5 \frac{4}{7} \)[/tex] to an improper fraction:

[tex]\[ 5 \frac{4}{7} = \frac{5 \times 7 + 4}{7} = \frac{35 + 4}{7} = \frac{39}{7} \][/tex]

Now, the fractions [tex]\( \frac{25}{6} \)[/tex] and [tex]\( \frac{39}{7} \)[/tex] need to have a common denominator to find the LCD.

Finding the Least Common Denominator (LCD)

To find the LCD, we need to determine the least common multiple (LCM) of the denominators [tex]6[/tex] and [tex]7[/tex]

The prime factorization of [tex]6[/tex] is [tex]\( 2 \times 3 \).[/tex]

The prime factorization of [tex]7[/tex] is [tex]\( 7 \).[/tex]

The LCM of [tex]6[/tex] and [tex]7[/tex] is [tex]\( 6 \times 7 = 42 \).[/tex]

Verify and Convert to Common Denominator:

Convert both fractions to have a denominator of [tex]42[/tex]

[tex]\[ \frac{25}{6} \times \frac{7}{7} = \frac{175}{42} \][/tex]

[tex]\[ \frac{39}{7} \times \frac{6}{6} = \frac{234}{42} \][/tex]

Now, [tex]\( \frac{25}{6} \) converts to \( \frac{175}{42} \) and \( \frac{39}{7} \) converts to \( \frac{234}{42} \).[/tex]

(a) Draw a diagram showing Janet and the kite.
(b) What is the length of the string of the kite?
Answer:

Answers

Hey there! :D

For this, you will need to draw your own diagram, but I think you can do this if I explain it. It should look like a triangle. Where the string is a vertex, and the kite is an upper vertex. The bottom is the distance. Look at the example. You can label the distances on it if you want to. 

c= length of the string (75m)

b= height of the kite (62m)

a will equal the distance between Janet and the spot on the ground beneath the kite. 

Now, we plug it into the Pythagorean theorem.

a^2+b^2= c^2

a^2+ 62^2= 75^2

Square the numbers.

a^2+3844= 5625

Subtract 3844 on both sides. 

a^2= 1781

Find the square root. 

√1781= 42.2 or 42.

Tim fisher received a 1200 discount loan to purchase a computer the loan was offered at 18% for 180 days find the interest in dollars and the proceeds for the following problem

Answers

The interest is $106.30 and the proceeds is approximately $1093.70

Calculating simple interest.

The simple interest is the amount of interest charges on the amount being borrowed and its paid by the borrower.

The simple interest can be determined by using the formula;
[tex]S. I = \dfrac{p\times r \times t}{100}[/tex]

[tex]S. I = \dfrac{1200\times 18 \times \dfrac{180}{365}}{100}[/tex]

Answer:

The correct answer is A).

Step-by-step explanation:

He have the quadratic functions f(x) = 16x²-240x+896. The first step should be to check if the coefficients 240 and 896 are divisible by 16, which is true. Then, extracting 16 as common factor we have

f(x) = 16(x²-15x+56).

Now we can use directly the formula to find the roots of a quadratic equation, or a more efficient way in terms of calculations. We must find to numbers such that their product is +56 and their addition or subtraction is -15. It is not difficult to check that -7 and -8 fulfill those conditions. Hence,

f(x) = 16(x²-15x+56)= 16(x-7)(x-8).

Therefore, the solutions are x=8 and x=7.

Final answer:

If buying a dozen bagels for $2.39 also gets an additional bagel for free, the cost per bagel when rounded to the nearest cent is $0.18.

Explanation:

The subject of your question is on the topic of unit cost. In this case, we will be calculating the cost per bagel when you buy a dozen bagels for $2.39 and get an additional bagel for free.

First, note that a dozen bagels means 12 bagels. But in this case, you get an extra bagel for free. So, you will have in total 13 bagels.Next, we divide the total cost by the total number of bagels to find the cost per bagel. That is, $2.39 divided by 13. When you do the calculation, you get approximately $0.184 per bagel.Since we need to round to the nearest cent, the final cost per bagel is $0.18 when rounded down.
