Answer:

This is a math problem. To solve it, you need to use algebra. Let me show you how.

Let x be the number of badges Katya sold. Then we can write an equation using the given information:

46 × 1.40 + 32 × 1.50 + 0.90 × x = 134

Simplifying the equation, we get:

64.4 + 48 + 0.9x = 134

Subtracting 64.4 and 48 from both sides, we get:

0.9x = 21.6

Dividing both sides by 0.9, we get:

x = 24

Therefore, Katya sold 24 badges.

Step-by-step explanation:

Angle A = 68 degrees

Angle B = 22 degrees

Side AB = 2.9 cm

The three values are approximate

=========================================================

Explanation:

a = BC = 2.7 and b = AC = 1.1 are the two legs of the right triangle.

Use the pythagorean theorem to find the length of the hypotenuse

a^2 + b^2 = c^2

2.7^2 + 1.1^2 = c^2

8.5 = c^2

c^2 = 8.5

c = sqrt(8.5)

c = 2.91547594742266

c = 2.9

The hypotenuse is c = AB = 2.9

--------------------

We then use trig ratios to find the two missing angles.

Let's say we ignore the hypotenuse and focus on the two legs of the triangle.

With respect to reference angle A, side BC is opposite and AC is adjacent

Use the tangent ratio to get

tan(angle) = opposite/adjacent

tan(A) = BC/AC

tan(A) = 2.7/1.1

tan(A) = 2.45454545454546

A = arctan(2.45454545454546)

A = 67.8336541779176

A = 68

Note: arctan is the same as inverse tangent or \(\tan^{-1}\). Make sure your calculator is in degree mode.

-------------------

Similarly,

tan(angle) = opposite/adjacent

tan(B) = AC/BC

tan(B) = 1.1/2.7

tan(B) = 0.4074074074074

B = arctan(0.4074074074074)

B = 22.166345822082

B = 22

Or you could use the value of A to get B = 90-A = 90-68 = 22. This works because A+B = 90 as we're working with a right triangle. In other words, A and B are complementary angles.

-------------------

In summary we found

A = 68

B = 22

AB = 2.9

The required position of the -2.25 lies above the -2.25 on the vertical number line.

Given that,
If -2.5 < -2.25, how are the positions of the two numbers related on the vertical number line is to be determined.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
Since -2.5 is 0.25 lower than -2.25, and also the -2.25 is greater than -2.5.
So on the vertical number line, -2.25 lies 0.25 units above the number -2.5.

Thus, the required position of the -2.25 lies above the -2.25 on the vertical number line.

At the same time, a vertical post measuring 8 inches casts an 18-inch shadow, while a nearby flower casts a 50-inch shadow. we can set up a proportion based on the shadow lengths and solve for the flower's height. the height of the flower is approximately 22.22 inches

Let's set up the proportion using the shadow lengths and the respective heights of the post and the flower. Since the shadow lengths are directly proportional to the heights, we have:
(Post height) / (Post shadow length) = (Flower height) / (Flower shadow length)
Plugging in the given values:
8 / 18 = (Flower height) / 50
To find the height of the flower, we can cross-multiply and solve for (Flower height):
8 * 50 = 18 * (Flower height)
400 = 18 * (Flower height)
Dividing both sides of the equation by 18:
(Flower height) = 400 / 18
(Flower height) ≈ 22.22 inches
Therefore, the height of the flower is approximately 22.22 inches when rounded to the nearest hundredth.

The diameter of the sphere is 1.2 meters.

We know that for a sphere of radius R, the surface area is given by the formula:

S = 4πR²

Where π = 3.14

Here we know that the surface area is 4.5216m²

Then we can replace that and find the radius:

4.5216m² = 4*3.14*R²

Solving for R:

R = √(4.5216m²/(4*3.14))

R = 0.6m

Then the diameter, two times the radius, is:

D = 2*0.6m

Step-by-step explanation:

Answer:

The choice C.

Step-by-step explanation:

\( {( \frac{ {2}^{ - 10} }{ {4}^{2} } )}^{7} = \frac{ {(2}^{ - 10}) ^{7} }{ {( {4}^{2}) }^{7} } = \frac{ {2}^{ - 10 \times 7} }{ {4}^{2 \times 7} } = \frac{ {2}^{ - 70} }{ {4}^{14} } \\ \\ = \frac{1}{ {2}^{70} \times {4}^{14} } \)

The formula for the given sequence is 1/(1x2)+1/(2x3)+1/(3x4)+...+1/(n(n+1)) = (n+1) [1/1! + (-1)^(n)/(n+1)!]

To find a formula for the given sequence, we can use the method of partial fractions. First, we can write each term as a fraction with a common denominator of (n+1):

1/(1x2) = (n+1)/(n+1)x1x2 = (n+1)/2!x(n+1)
1/(2x3) = (n+1)/(n+1)x2x3 = (n+1)/3!x(n+1)
1/(3x4) = (n+1)/(n+1)x3x4 = (n+1)/4!x(n+1)
...
1/(n(n+1)) = (n+1)/(n+1)xn(n+1) = (n+1)/(n+1)!x(n+1)

Then, we can add all the terms together:

1/(1x2)+1/(2x3)+1/(3x4)+...+1/(n(n+1)) = [(n+1)/2!x(n+1)] + [(n+1)/3!x(n+1)] + [(n+1)/4!x(n+1)] + ... + [(n+1)/(n+1)!x(n+1)]
= (n+1) [1/2! + 1/3! + 1/4! + ... + 1/(n+1)!]
= (n+1) [1/1! - 1/2! + 1/2! - 1/3! + 1/3! - ... + (-1)^(n)/(n+1)!]
= (n+1) [1/1! + (-1/2! + 1/2!) + (-1/3! + 1/3!) + ... + (-1)^(n)/(n+1)!]

We can simplify the terms in the brackets by noticing that every pair of adjacent terms cancels out, leaving only the first and last terms:

= (n+1) [1/1! + (-1)^(n)/(n+1)!]

Thus, the formula for the given sequence is:

1/(1x2)+1/(2x3)+1/(3x4)+...+1/(n(n+1)) = (n+1) [1/1! + (-1)^(n)/(n+1)!]

According to Hunt et al., young people have agency, or the ability to choose whether or not to use drugs.

Agency refers to the capacity of individuals to make choices and take actions based on their own free will and personal autonomy. It implies that individuals, including young people, have the ability to exercise control over their decisions and behaviors, including the choice to engage in drug use or abstain from it.

According to Hunt et al., young people have agency, or the ability to choose whether or not to use drugs.

Hunt et al. suggest that young people possess agency in the context of drug use. This means that they have the cognitive and emotional ability to make decisions regarding drug use based on their own values, beliefs, and circumstances. It recognizes that young people are not passive recipients of external influences but rather active participants in shaping their own behaviors.

Acknowledging young people's agency regarding drug use is important for promoting a comprehensive and empowering approach to drug prevention and education. It emphasizes the significance of providing accurate information, fostering critical thinking skills, and promoting self-efficacy in young individuals. By recognizing their agency, interventions can focus on empowering young people to make informed and responsible choices about drug use, considering potential risks and consequences.

It is important to note that while agency acknowledges individuals' ability to make choices, it does not exist in isolation from other factors that can influence decision-making. Social, environmental, and systemic factors, such as peer pressure, socioeconomic conditions, and access to drugs, can shape and influence the choices available to young people. Recognizing agency does not negate the need for supportive environments, education, and effective prevention strategies to help young people navigate the complex landscape of drug use decisions.

Answer:

it is D rectangle i just did the quiz on Edmentum and got it right

Step-by-step explanation:

The given problem is about finding the linear speed of a vehicle when each of its tire has a diameter of 32 inches and is moving at 800 revolutions per minute. In order to solve this problem, we will use the formula `linear speed = (pi) (diameter) (revolutions per minute) / (1 mile per minute)`.

Since the diameter of each tire is 32 inches, the radius of each tire can be calculated by dividing 32 by 2 which is equal to 16 inches. To convert the units of revolutions per minute and inches to miles and hours, we will use the following conversion factors: 1 mile = 63,360 inches and 1 hour = 60 minutes.

Now we can substitute the given values in the formula, which gives us:

linear speed = (pi) (32 inches) (800 revolutions per minute) / (1 mile per 63360 inches) x (60 minutes per hour)

Simplifying the above expression, we get:

linear speed = 107200 pi / 63360

After evaluating this expression, we get the linear speed of the vehicle as 5.36 miles per hour. Rounding this answer to the nearest tenth gives us the required linear speed of the vehicle which is 5.4 miles per hour.

Therefore, the linear speed of the vehicle is 5.4 miles per hour.
