Answer:

[tex]\Large \boxed{\sf x=-\frac{3}{2}}[/tex]

Step-by-step explanation:

We're looking for the value of x that satisfies the following equation :

[tex]\sf 3 (2x+1) = 4x[/tex]

We need to isolate x.

First, let's expand left side :

[tex]\sf 3\times 2x+3\times1=4x\\6x+3=4x[/tex]

Now let's substract 4x from both sides :

[tex]\sf 6x+3-4x=4x-4x\\2x+3=0[/tex]

Substract 3 from both sides :

[tex]\sf 2x+3-3=0-3\\2x=-3[/tex]

Finally, let's divide both sides by 2 :

[tex]\sf \frac{2x}{2} =-\frac{3}{2} \\\boxed{\sf x=-\frac{3}{2}}[/tex]

Anna's monthly Salary in June was $3600 as she received a 20% rate and her monthly Salary in July was $2880 as she received a 20% pay cut from June.

It is given to us that: Ana's salary in May =3000$

in June she received 20% raise

the amount she received in June after 20% raise = 3000 x 20/100

= 30 x 20 = 600

we have to first find Ana's salary at the end of June month with 20% raise. and then her salary after the end of July month with the pay cut of 20%.

Ana's salary after June month when she got 20% raise in his salary after May:

= 3000 + (20% x 3000)

= 3000 + (20/100 x 3000)

= $3600

her new salary after June will be 3600$.

therefore, she received 3600 in June.

in July she received 20% pay cut.

To find Ana's monthly salary after the two changes in June and July.

Ana's salary after June month when she got 20% raise in his salary after May = $3600

now she got a pay cut of 20% on his new salary from July month,

= 3600 - (20% x 3600)

= 3600 + (20/100 x 3600)

= 3600 - 720

= $2880

so, her salary after that would be equal to $2880.

Answer: To solve this problem, we can start by drawing a diagram of the two triangles and the line connecting their hypotenuses. Let's label the height of the first triangle as h1, the width of the second triangle as w2, and the slope of the line as m.

We know that the hypotenuse of a right triangle is always longer than either of its legs, so we can conclude that h1 < w2. We also know that the height of the second triangle is 12 units, so we can label that as h2 = 12.

Using the Pythagorean theorem, we can express the lengths of the hypotenuses in terms of their legs:

h1^2 + 3^2 = L^2, where L is the length of the first hypotenuse

w2^2 + 12^2 = L^2, where L is the length of the second hypotenuse

Setting these two expressions equal to each other, we can solve for h1 in terms of w2:

h1^2 + 3^2 = w2^2 + 12^2

h1^2 = w2^2 + 12^2 - 3^2

h1^2 = w2^2 + 141

h1 = sqrt(w2^2 + 141)

Now, we can use the fact that the hypotenuses lie on the same line to write an equation for that line:

y = mx + b

where b is the y-intercept of the line. Since the hypotenuses intersect the y-axis at the points (0,h1) and (0,12), we know that b = (h1 + 12)/2. Therefore, our equation becomes:

y = mx + (h1 + 12)/2

To find the slope of the line, we can use the fact that the rise (change in y) over run (change in x) is the same for both triangles. We can express this as:

(h1 - 12) / 3 = 12 / w2

Solving for h1 in terms of w2 and simplifying, we get:

h1 = (36/w2) + 12

Substituting this expression for h1 into our equation for the line, we get:

y = mx + ((36/w2) + 24)/2

y = mx + (18/w2) + 12

Comparing this to the general form of the equation for a line, y = mx + b, we see that the slope is simply:

m = 18/w2

Substituting w2 = 3 (since we were given that the width of the second triangle is 3 units), we get:

m = 18/3 = 6

Therefore, the slope of the line is 6.

To find the lower bound and upper bound of the difference m-n, we need to first find the possible range of values for m and n.

• For m rounded to 1 decimal place, the actual value could be anywhere between 48.15 and 48.25 (since the digit in the second decimal place could be anything from 0 to 9, and we round to the nearest 0.1).

• For n rounded to 1 decimal place, the actual value could be anywhere between 6.65 and 6.75.

Now, we can calculate the lower bound and upper bound of m-n:

Lower bound of m-n = (48.15 - 6.75) = 41.4

Upper bound of m-n = (48.25 - 6.65) = 41.6

Therefore, the lower and upper bounds of m-n are 41.4 and 41.6, respectively.

AE and CD intersect at point B then angle ABD = 152°

A straight angle in mathematics is one with a degree value of 180. Because it resembles a straight line, it is called straight. Essentially, two rays linked end to end create an angle according to the definition of angles in mathematics. As a result, where the rays are linked at endpoints, the two 180-degree angle rays are subtended in the opposite direction.

AE and CD intersect at point B,

angle DBE = 48,

and AE is a straight line,

So the sum of angles on a straight line is 180,

We have to find the angle ABD,

Answer:

(6,45)

Step-by-step explanation:

To graph each ratio relationship in the coordinate plane, we can plot the ordered pairs (time, distance) for each leg of the trip. For the first leg from Chicago to Los Angeles, the plane travels 15 miles every 2 minutes. So we can plot the following points:

(0, 0) - starting point

(2, 15) - after 2 minutes, the plane has traveled 15 miles

(4, 30) - after 4 minutes, the plane has traveled 30 miles

(6, 45) - after 6 minutes, the plane has traveled 45 miles

(8, 60) - after 8 minutes, the plane has traveled 60 miles

We can plot these points on a coordinate plane, with time on the x-axis and distance on the y-axis. The resulting graph would show a straight line with a slope of 7.5 (rise of 15/2 and run of 1).

For the second leg from Los Angeles to Chicago, the plane travels 25 miles every 3 minutes. So we can plot the following points:

(0, 0) - starting point

(3, 25) - after 3 minutes, the plane has traveled 25 miles

(6, 50) - after 6 minutes, the plane has traveled 50 miles

(9, 75) - after 9 minutes, the plane has traveled 75 miles

(12, 100) - after 12 minutes, the plane has traveled 100 miles

We can plot these points on the same coordinate plane as the first leg. The resulting graph would also show a straight line with a slope of 8.33 (rise of 25/3 and run of 1).

The two graphs would intersect at the point (6, 45), which represents the halfway point of the round trip.

Answer:

(-2/5, 11/5)

Step-by-step explanation:

We can use the formula for finding a point that divides a line segment into a given ratio. Let P be the point on the line segment QR that partitions it in the ratio 2:3. Then we have:

P = ( (3x2 + 2x1)/(3+2), (3y2 + 2y1)/(3+2) )

where (x1, y1) = (-8, -8) is the coordinates of Q and (x2, y2) = (2, 7) is the coordinates of R.

Substituting the values, we get:

P = ( (32 + 2(-8))/(3+2), (37 + 2(-8))/(3+2) )

P = ( (-2/5), (11/5) )

Therefore, the coordinates of the point P on the directed line segment QR that partitions it in the ratio 2:3 are (-2/5, 11/5).

The probability that each of you orders a different type of sandwich is 72%.

To find the probability that each of you orders a different type of sandwich, we can use the counting principle.
Step 1: Determine the total number of ways you and your friends can order sandwiches.

Since there are 10 types and each of you can choose any type, there are 10 * 10 * 10 = 1000 possible ways to order.
Step 2: Calculate the number of ways you can order different types of sandwiches.

For the first person, there are 10 choices.

For the second person, there are 9 remaining choices (since their sandwich must be different from the first person's). For the third person, there are 8 remaining choices (different from both the first and second person's choices). So there are 10 * 9 * 8 = 720 ways to order different types of sandwiches.
Step 3: Calculate the probability of ordering different types of sandwiches.

Divide the number of ways to order different sandwiches by the total number of ways to order:
Probability = (Number of ways to order different sandwiches) / (Total number of ways to order)
Probability = 720 / 1000 = 0.72 or 72%.

Answer: 59.02 square inches

Step-by-step explanation:

We can use the formulas for the volume and surface area of a sphere to solve this problem.

The formula for the volume of a sphere is:

V = (4/3)πr^3

Where V is the volume, r is the radius, and π is pi (approximately equal to 3.14159).

We know that the volume of the sphere is 33.51 cubic inches, so we can plug that in and solve for the radius:

33.51 = (4/3)πr^3

r^3 = (3/4) * (33.51/π)

r^3 = 10.56

r ≈ 2.17

Now that we know the radius is approximately 2.17 inches, we can use the formula for the surface area of a sphere to find the surface area:

A = 4πr^2

A = 4π(2.17)^2

A ≈ 59.02 square inches

Therefore, the surface area of the sphere is approximately 59.02 square inches.

The average speed of NFL players varies by position and other factors, and while the forty-yard dash is a common measure of speed, it's important to consider other factors and potential biases when comparing average times between different years.

The average speed of NFL players can vary depending on their position and other factors such as age, height, and weight. The forty-yard dash is a common measure of speed and agility for NFL players.

Regarding the question about whether NFL players were significantly faster between 2012-2014 compared to previous years, we would need to compare the average forty-yard dash times for running backs and wide receivers from 2012-2014 to the average times from prior years to determine if there was a significant difference.

However, it's worth noting that the average forty-yard dash time can be influenced by a variety of factors, including changes in the testing conditions, differences in the player population being tested, and changes in training and coaching techniques. Therefore, we cannot make any definitive conclusions about changes in player speed based solely on this one measure.

y = - [tex]\frac{1}{2}[/tex] (x + 3)² + 4

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

here (h, k ) = (- 3, 4 ) , then

y = a(x - (- 3) )² + 4 , that is

y = a(x + 3)² + 4

to ind a substitute the point (1, - 4 ) into the equation

- 4 = a(1 + 3)² + 4

- 4 = a(4)² + 4 ( subtract 4 from both sides )

- 8 = 16a ( divide both sides by 16 )

- [tex]\frac{8}{16}[/tex] = a , that is

a = - [tex]\frac{1}{2}[/tex]
