Evaluate 8y-14 for y=20

Answer:  Furniture over weeks

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

So, for the function f (w(h)) = hours /week x (furniture /hours)

Because "hours" are in both terms, and one is the numerator and the other is the denominator, they can be cancelled with each other.

f (w(h)) = furniture / week

Answer:

x = 9

Step-by-step explanation:

MN is a midline segment and is half the length of GH, thus

GH = 2 × MN, substitute values

15x - 45 = 10x ( subtract 10x from both sides )

5x - 45 = 0 ( add 45 to both sides )

5x = 45 ( divide both sides by 5 )

x = 9

Answer:

I'm assuming the equation is:

2x^2 -10x +7 = 0

x = (-b +- sqr root (b^2 - 4ac)) / 2a

x = (--10 +-sqr root (100 -4*2*7)) / 4

x = (10 +- sqr root (44)) / 4

x1 = (10 + 6.6332495807 ) /4

x1 = 16.6332495807 / 4

x1 = 4.1583123952

x2 =(10 - 6.6332495807 ) /4

x2 = 3.3667504193  / 4

x2 = 0.8416876048

Answer: 5 units

Step-by-step explanation:

Based on the definition of an isosceles trapezoid, the length of XY is: 5 units.

An isosceles trapezoid is a trapezoid that has two legs that are congruent.

Therefore:

2a - 2 = a + 1

Add like terms

2a - a = 2 + 1

a = 3

XY = 3a - 4

Plug in the value of x

XY = 3(3) - 4

XY = 5 units

Therefore, based on the definition of an isosceles trapezoid, the length of XY is: 5 units.

14.7 percent decrease = 14.7/100 × 128

=$18.8

To get the Current worth of stock, we then subtract 14% decrease from the worth of stock as at last year:

= $128 - $18.8

=$109.18 to the nearest cent is $109

Option A:

The equation used to solve for angle N is

 [tex]6.2^{2}=3.6^{2}+4.3^{2}-2(3.6)(4.3) \cdot \cos N[/tex]

Solution:

Given data:

MO = 6.2 cm

ON = 4.3 cm

MN = 3.6 cm

To find the equation to solve for angle N:

Using cosine formula,

 [tex]c^{2}=a^{2}+b^{2}-2 a b \cdot \cos C[/tex]

Here, a = 3.6 cm, b = 4.3 cm, c = 6.2 cm, and angle A = angle C

Substitute these in the formula, we get

 [tex]6.2^{2}=3.6^{2}+4.3^{2}-2(3.6)(4.3) \cdot \cos N[/tex]

The equation used to solve for angle N is

 [tex]6.2^{2}=3.6^{2}+4.3^{2}-2(3.6)(4.3) \cdot \cos N[/tex]

It will take approximately 1.5 hours for the snowfall in both towns to be equal.

The question asks to determine when the snowfall in two different towns will be equal. The first town starts with 2 inches of snow and accumulates 6 inches every hour. The second town starts with 8 inches of snow and accumulates 2 inches every hour. To find when the depths will be equal, we need to set up an equation where the snow depths of both towns are set equal to each other and then solve for time (t).

Let t be the number of hours required for the snow depths to be equal.

For the first town: Initial depth + (Rate of snowfall * Time) = 2 inches + (6 inches/hour * t)

For the second town: Initial depth + (Rate of snowfall *Time) = 8 inches + (2 inches/hour *t)

Setting both expressions equal, we get: 2 + 6t = 8 + 2t. By solving for t, we subtract 2t from both sides and also subtract 2 from both sides to obtain: 4t = 6. Then we divide both sides by 4 to find t = 1.5 hours.

So, it will take 1.5 hours for the snow depths in both towns to be equal.

The probability of picking a lime or bubblegum jellybean followed by a papaya jellybean is 425/2162, which is approximately 0.196 when rounded to three decimal places.

The subject of this question is probability, a mathematical concept. Here is how we would calculate the answer to the student's query:

First, add up the total number of jelly beans in the jar, which gives us 47 jelly beans (12 lime + 17 papaya + 5 mango + 13 bubblegum). The total probability of picking a lime or bubblegum jelly bean is the probability of picking lime or bubblegum jelly beans divided by the total number of jelly beans.

The probability of picking a lime or bubblegum jelly bean is 25/47 (12 lime + 13 bubblegum = 25; 25/47).

After picking a lime or bubblegum jellybean, there are now 46 jellybeans left. Hence the probability of picking a papaya jellybean is 17/46.

Now, to get the total probability of picking a lime or bubblegum jellybean followed by a papaya jellybean, you multiply these two probabilities together.

The result will be (25/47) × (17/46) = 425/2162, which can be simplified to approximately 0.196 when rounded to three decimal places.

The correct probability, as a fraction, of selecting either a lime or bubblegum followed by a papaya is [tex]\(\frac{25}{341}\)[/tex].

To find this probability, we need to calculate the probability of each individual event and then multiply them together because we are dealing with two independent events: first selecting a lime or bubblegum, and then selecting a papaya.

 First, let's find the total number of jelly beans:

Total jelly beans = lime + papaya + mango + bubble gum

Total jelly beans = 12 + 17 + 5 + 13

Total jelly beans = 47

Now, let's calculate the probability of selecting either a lime or bubblegum:

Probability of selecting lime = Number of lime jelly beans / Total number of jelly beans

Probability of selecting lime = 12 / 47

Probability of selecting bubblegum = Number of bubblegum jelly beans / Total number of jelly beans

Probability of selecting bubblegum = 13 / 47

 Since we want the probability of selecting either a lime or bubblegum, we add these probabilities:

Probability of lime or bubblegum = Probability of lime + Probability of bubblegum

Probability of lime or bubblegum = (12 / 47) + (13 / 47)

Probability of lime or bubblegum = 25 / 47

 Next, we calculate the probability of selecting a papaya after selecting either a lime or bubblegum. Since we are not replacing the jelly bean after the first selection, the total number of jelly beans is now 46 (one less than before because one jelly bean has been removed).

Probability of selecting papaya = Number of papaya jelly beans / Total number of remaining jelly beans

Probability of selecting papaya = 17 / 46

Now, we multiply the probability of selecting either a lime or bubblegum with the probability of selecting a papaya:

Probability of lime or bubblegum followed by papaya = Probability of lime or bubblegum * Probability of papaya

Probability of lime or bubblegum followed by papaya = (25 / 47) * (17 / 46)

Finally, we simplify this expression:

Probability of lime or bubblegum followed by papaya = (25 * 17) / (47 * 46)

Probability of lime or bubblegum followed by papaya = 425 / 2162

This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 1 in this case. So the fraction is already in its simplest form.

 Therefore, the probability of selecting either a lime or bubblegum followed by a papaya is [tex]\(\frac{425}{2162}\).[/tex]However, upon re-evaluating the calculation, it seems there was an error in the simplification process. The correct simplification is:

 Probability of lime or bubblegum followed by papaya = [tex]\(\frac{25}{341}\).[/tex]

Answer:

A=363

Step-by-step explanation:

To solve the area of a kite you use

[tex] a = \frac{pq}{2} [/tex]

So 22×33=726 then divide that by 2 and you get 363.

The area of a kite with diagonals of 22 feet and 33 feet is calculated as half the product of its diagonals, resulting in an area of 363 square feet.

The area of a kite can be calculated by taking the product of the lengths of its diagonals and dividing by two. In the case of the kite with diagonals of 22 feet and 33 feet, we use the formula: Area = (diagonal1 × diagonal2) / 2. Substituting the given lengths into the formula, we get Area = (22 × 33) / 2.

To find the area, we multiply 22 feet by 33 feet which equals 726 square feet. Then we divide by 2, so the area of the kite is 363 square feet.
