Find the value of X.

Answer:

d 125

Step-by-step explanation:

Supplementary angles add to 180 degrees

Let x be the supplement to the 55 degree angle

55+ x =180

Subtract 55 from each side

55+x-55 =180-55

x = 125

Answer:

$25

Step-by-step explanation:

Since it was originally $100, 80% off would mean he would only have to pay $20 for it. But sales tax, you would have to add 10% back of the sale price which was $20. so, 10% of 20 is $5. The sale price, $20, plus the $5 is 25 dollars he had to pay.

After waiting for a 80% off discount, Sam purchased the dresser for $20. Including a 10% sales tax, he paid a total of $22.

In this problem, we first need to figure out what 80% off of the original $100 price is. This can be done by converting the 80% discount to a decimal (0.8) and then multiplying it by the original cost ($100). This gives us $80.

However, since this is the amount discounted, we subtract it from the original price to get the sale price of the chest of drawers, so $100 - $80 = $20. This is how much Sam paid before sales tax.

Next, we need to calculate the sales tax amount. We first convert the 10% sales tax to a decimal (0.10), and then we multiply it by the sale price ($20). This gives us $2 in sales tax.

Finally, we add the sales tax to the sale price to get the total amount Sam paid for the chest of drawers: $20 + $2 = $22. So, Sam paid a total of $22 for the chest of drawers.

Answer:

The center of the circle is at: C=(−5,4).

The radius of the circle is r=3.

Step-by-step explanation:

The equation of the circle is (x + 5)² + (y − 4)² = 3². Then the center of the circle is at (−5, 4) and the radius of the circle is 3 units.

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

The equation of the circle is given as (x + 5)² + (y − 4)² = 9.

The equation can be written as

(x + 5)² + (y − 4)² = 3²

Then the center of the circle is at (−5, 4) and the radius of the circle is 3 units.

Answer:

Step-by-step explanation:

Answer:

The shape of the cross-section is a square. The plane is parallel to the base of the triangular pyramid and the base is a square.

Step-by-step explanation:

If you double the radius of a circle, the circumference also doubles; however, the number of radii that can fit around the circumference remains unchanged.

If you double the radius of a circle, the circumference of the circle also doubles because the formula for the circumference of a circle is 2πr (`r` being the radius). Thus if `r` becomes 2r, the circumference becomes 2(2πr) or 4πr, which is twice the original circumference.

Similarly, if you try to fit radii around the circle, you would find that exactly the same number of radii will fit around the circle as before. This is because the radius is the distance from the center of the circle to the circumference, and no matter how long the radius is, you can always fit exactly 2π radii around the circumference. Doubling the radius length therefore does not alter the number of radii that can fit around the circle.

Answer:

The correct answer is 2 pi d

Step-by-step explanation:

Without an actual box plot to reference, it's impossible to accurately determine which set of donation amounts correctly corresponds to the box plot in question.

The question seeks to identify the set of donation amounts that matches a given box plot. When analyzing sets of donation amounts to determine which one aligns with a box plot, we look for key features such as the minimum, the maximum, the median, and the quartiles. These features divide the data set into four parts of equal importance, helping us understand the distribution of the data.

Given that there isn't an actual box plot provided, we would typically compare the given options against the features one would expect to find in a box plot:

However, without the specific details of the box plot, such as the exact median or quartile values, we cannot accurately determine which set of donations matches the box plot. Typically, an analysis would involve calculating or identifying these characteristic numbers from each option and then seeing which one fits the description given by the box plot.

Answer: Total Volume =  15π + 18 π= 33π cubic mm

Step-by-step explanation:

What is the volume of the composite figure? Leave the answer in terms of π.

_33π mm3

We have a cone here conjoined to a semi-sphere.

so

Cone volume:  C = (1/3)*(πr^2) * h

semi-sphere volume :  V = (1/2)* (4/3) * (π * r^3)

r = 3 mm  and  h = 5mm

so   C = (1/3)*(π  (3)^2) * 5 =  15π  cubic mm

V = (1/2)* (4/3) * (π * 3^3) = 18 π cubic mm

Total Volume =  15π + 18 π= 33π cubic mm

Step-by-step explanation:

Combine like terms:

[tex]-3p^3+ 5p^2- 2p -p^3 - 8p^2-15p=-4p^3-3p^2-17p[/tex]

The (-3p³ + 5p² - 2p) +(-p³ - 8p² – 15p) can be simplified as -4p³ - 3p² - 17p

Polynomials are expression that can have constant, variables and exponents.

Therefore,

(-3p³ + 5p² - 2p) + (-p³ - 8p² – 15p)

we have to use the positive value outside to open the bracket.

-3p³ + 5p² - 2p - p³ - 8p² - 15p

-3p³ - p³ + 5p² - 8p² - 2p - 15p

-3p³ - p³ + 5p² - 8p² - 2p - 15p = -4p³ - 3p² - 17p

Answer:

28 years

Step-by-step explanation:

To find the number of years that the investment will reach $3500, we can use the formula of compound interest:

P = Po * (1+r)^t

where P is the final value, Po is the inicial value, r is the annual interest and t is the time in years.

In this question, P = 3500, Po = 1800 and r = 2.46% = 0.0246, so:

3500 = 1800 * (1+0.0246)^t

1.0246^t = 3500/1800

1.0246^t = 1.9444

Using logarithm in both sides:

log(1.0246^t) = log(1.9444)

t*log(1.0246) = 0.2888

t * 0.0106 = 0.2888

t = 0.2888 / 0.0106 = 27.2453 years

So the investment will reach $3500 after 28 years (rounding the result up, because after 27 years the investment will not reach $3500)

Final answer:

The number of ways 15 students can arrange themselves in 15 seats is calculated using permutations and is equal to 15 factorial (15!).

Explanation:

The question involves finding the number of different ways to arrange 15 students in 15 seats, which is a combinatorial problem in mathematics. This problem can be solved by using the concept of permutations. Indeed, if we have 15 distinct objects (students) and we want to arrange them in 15 distinct positions (seats), we need to calculate the number of permutations of 15 items taken 15 at a time.

The formula for the number of permutations of n objects taken r at a time is P(n, r) = n! / (n-r)!, where ! denotes the factorial of a number. For this case, since we are permuting all 15 students (n = 15), the number of ways they can arrange themselves in 15 seats is simply 15! (15 factorial).

Answer:

73.8 cubic mm.

Step-by-step explanation:

The volume of a square V is given by the formula:

[tex]V= \frac{4}{3}\pi r^{2}[/tex] where r is the radius of the sphere.

We also know that the diameter is two times the radius, so in this case if the diameter is 8.4 mm, then the radius is 4.2 mm.

Now we substitute the information in the formula, taking into account that we are going to use the value of 3.14 for [tex]\pi[/tex].

[tex]V= \frac{4}{3}\pi r^{2}\\ V= \frac{4}{3}(3.14)(4.2)^{2} \\V=\frac{(4)(3.14)(17.64)}{3} \\V=\frac{221.55}{3}=73.8528[/tex]

Which rounded to the nearest tenth is 73.8. Thus, the sphere's volume is 73.8 cubic mm.

Answer:

V = 310.2 mm³

Step-by-step explanation:

The formula for volume of a sphere is given as:

V = 4/3 * π * r³

where r is the radius of the sphere.

We are given the diameter in the question. Diameter is twice the radius. So, radius = diameter/2

     radius = 8.4/2

     radius = 4.2 mm

V = 4/3 * π * r³

  = 4/3 * 3.14 * (4.2)³

V = 310.181

V = 310.2 mm³

Answer:

x=250

Step-by-step explanation:

150= 3/5 x

50 = 1/5 x

x=50×5

x=250

Final answer:

To solve the equation 150 = 3/5 x for x, divide both sides by 3/5, which is equivalent to multiplying by its reciprocal (5/3), resulting in x being equal to 250.

Explanation:

To find the value of x in the equation 150 = 3/5 x, you first divide both sides of the equation by 3/5 to isolate x. This can be done by flipping the fraction and multiplying, as the division by a fraction is the same as multiplication by its reciprocal.

The process is as follows:

150 = (3/5) x

150 * (5/3) = x

50 * 5 = x

250 = x

Therefore, the value of x is 250.
