To find the width of the image on the tablet, set up a proportion using the diagonals of the computer monitor and the tablet. Solve for the unknown width using cross multiplication.So,on tablet it would be 0.84mm.

Explanation:

To determine the width of the image on the tablet, we can use a proportion based on the diagonals of the computer monitor and the tablet. The proportion can be set up as follows:

Computer Diagonal / Tablet Diagonal = Computer Width / Tablet Width

Substituting the given values, we have:

21 inches / 9.1 inches = 19 centimeters / x

Cross multiplying and solving for x, we get:

x = (9.1 inches * 19 centimeters) / 21 inches

Converting the units, the width of the image on the tablet should be approximately 8.43 centimeters=0.84mm

Answer:

5127079.21 cubic feet

Step-by-step explanation:

The silo is in the shape of a cylinder and a cone.

The volume of the silo will be the sum of the volumes of the cylinder and the cone.

Therefore, its volume is:

[tex]V = \pi r^2h + \frac{1}{3} \pi rH[/tex]

where r = radius of cylinder and cone

h = height of cylinder

H = height of cone

The radius of the base is 120 feet, the height of the roof (cone) is 25 feet. The height of the entire silo is 130 feet. This means that the height of the cylinder is:

130 - 25 = 105 feet

Therefore, the volume of the silo is:

[tex]V = (\pi * 120^2 * 105) + (\frac{1}{3} * 120^2 * 25)\\\\V = 4750088.09 + 376991.12\\\\V = 5127079.21 ft^3[/tex]

The volume of the silo is 5127079.21 cubic feet.

Answer: 0.15km/min and 0.3km in 2 mins

Step-by-step explanation:

Given Data:

Cyclists speed = 9km/hr

1. Some traveling 60 km/h is traveling one km/min

60/60= 1 km/min

Rate in km/min

= 9km/hr / 60min

= 3/20 km/min

= 0.15 km/min

Kilometers travelled in 2mins

= 2 / 60

= 1 / 30

= 9km/hr * 1 / 30

= 9 / 30

= 0.3 km in 2mins

Answer:

Rate(in km/min) = 0.15 km/min

Distance traveled in 2 mins = 0.3 km

Step-by-step explanation:

Rate = 9 km/hr

1 hr = 60 mins

In 60 minutes, the cyclist rides 9 km

in 1 minute, the cyclist will ride 9/60 km

Therefore, the rate in km/min = 9/60 km/min

Rate(in km/min) = 0.15 km/min

Since the cyclist rides 0.15 km in 1 min,

In 2 mins, the cyclist will ride 0.15 * 2 km = 0.3 km

Distance traveled in 2 mins = 0.3 km

Answer:

k=10°

Step-by-step explanation:

<ZYX

<ZYM + <ZYX = 180° ( angle on straight line)

115° + <ZYX = 180°

<ZYX = 180° - 115°

<ZYX = 65°

k

<YZX + <ZXY + <ZYX = 180° ( sum of interior angles of a triangle)

(4k + 5)° + (6k + 10)° + 65° = 180°

10k + 80° = 180°

10k = 180° - 80°

10k = 100°

Multiplying both sides by 10

k = 100°

10

k = 10°

Answer:

1. h = h₀ + u×t - 1/2×g×t²

2. 2.95 s

3. 152.14 ft

4. 3.07 s

Step-by-step explanation:

The given parameters are;

Vertical velocity of the balloon = 95 ft/s

Height from which the balloon is released = 12 feet

The function is h = h₀ + u×t - 1/2×g×t²

Where:

h = Height of the balloon at time t

h₀ = Initial height of the balloon = 12 feet

u = Initial upward velocity of the balloon = 95 ft/s

t = Time duration of motion

g = Acceleration due to gravity = 32.2 ft/s²

2. The time to maximum height is found from;

v = u - g·t

Where:

v = Final velocity = 0 m/s at maximum height

∴ 0 = 95 - 32.2 × t

32.2·t = 95

t = 95/32.2 = 2.95 s

Therefore, the time it will take to reach maximum height = 2.95 s

3. From h = h₀ + u×t - 1/2×g×t², we have;

h = 12 + 95×2.95 - 1/2×32.2×2.95² = 152.14 ft

4. Therefore;

152.14 = 0×t + 1/2 × 32.2 × t²

t² = 152.14/16.1 = 9.45 s

t = √9.45 = 3.07 s

Answer:

The function is: y(t) = 12 + 95*t - 16.085*t²

The time it'll take to reach the maximum height is: 2.95 s

The maximum height is: 152.27 ft

The time it'll take to hit the ground is: 12 s

Step-by-step explanation:

The water ballon is under the constant acceleration of gravity, therefore it's movement can be modelled by the equations that describe constant acceleration movement, as shown below:

y(t) = y(0) + v(0)*t - 0.5*g*t²

The acceleration is negative, because they are contrary to the movement. Applying the data form the problem, we have:

y(t) = 12 + 95*t - 0.5*32.17*t²

y(t) = 12 + 95*t - 16.085*t²

This equation describes a parabolla, therefore the time at which it achieves the maximum height is the "x" coordinate for the vertex, which can be found by using the formula below:

t = (-b)/[2*a]

t = (-95)/[2*(-16.085)] = -95/(-32.17) = 2.95 s

And the maximum height is:

y(2.95) = 12 + 95*2.95 - 16.085*(2.95)² = 152.27 ft

The time it'll take to reach the ground  is:

y(0) = 12 + 95*0 - 16.085*(0)² = 12 s

A bag contains 8 white balls and 3 yellow balls. Two balls are selected from the bag without replacement.

Step-by-step explanation:

The outcome of an independent variable is not affected by previous outcomes or actions, while the outcome of dependent variables is affected by previous outcomes or actions.

The outcome from independent variable is not affected by old outcomes or actions, while the outcome of dependent variables is affected by old outcomes or actions.

An independent variable is exactly when it sounds like. It is a variable that stands alone, changed by the other variables you are trying to measure.

A spinner is divided into three sections. The spinner is spun three times.

a. independent, since the outcome is not affected by previous spins. A number cube is rolled twice.

b. independent, since the outcome is not affected by previous rolling.

c. not  independent, since the new outcome depends on the balls that were drawn before.

Thus, the outcome will be an independent variable which is not affected by previous outcomes.

Answer:

82 students

Step-by-step explanation:

The total number of students who attended the dance can be found by subtracting the initial rental cost from the total cost, and then dividing this amount by the cost per student. The number of students who attended the dance was 82.

This problem can be solved with a little bit of algebra. The initial cost of the building was $120, and there was an additional cost of $2.50 for each student who attended. The total cost was $325. Therefore, in order to determine how many students attended the dance, you would first need to subtract the initial cost of the building from the total cost. This leaves us with $325 - $120 = $205.

Next, you would divide this amount by the cost per student. $205 ÷ $2.50 = 82.

Therefore, the number of students who attended the dance was 82.

C. Parabola

Step-by-step explanation:

A line parallel will cut only one cone (upper or lower cone, not both) making it a parabola

Answer:

The radius has an increase of 41.4%

Step-by-step explanation:

We have that the surface area formula is equal to:

a = 4 * pi * r ^ 2

in this case if you assume an area of 100 and we calculate the radius it would be:

100 = 4 * pi * r ^ 2

we solve for r:

r ^ 2 = 100/4 * pi

r ^ 2 = 100 / (4 * 3.14)

r ^ 2 = 7.9617

r = 2,822

now if we double the area, that is 200:

r ^ 2 = 200 / (4 * 3.14)

r ^ 2 = 15.9236

r = 3,990

So the change of the radius would be:

3.99 / 2,822 = 1,414

That is to say that the radius has an increase of 41.4%

Answer:

they use 212 gallons

Step-by-step explanation:

(68.9/32.5)*100

the division by 32.5 is to determine the amount of water one percent would be, so multiplying it by 100 will give you the total amount

Final answer:

To find the total daily water usage of a family using 68.9 gallons per day for drinking, which is 32.5% of their total usage, you divide the amount of water for drinking by 0.325. The calculation shows the family uses about 212 gallons of water per day.

Explanation:

The question asks us to calculate the total daily water usage of a family if they use 68.9 gallons per day for drinking, which represents 32.5% of their total daily use. To find the total water use, we divide the amount of water used for drinking by the percentage that represents drinking water.

Step-by-step Calculation:

Convert the percentage to a decimal by dividing 32.5 by 100, giving us 0.325.

Divide the gallons used for drinking by this decimal: 68.9 gallons / 0.325 = 212 gallons (rounded to the nearest whole gallon).

Therefore, the family uses approximately 212 gallons of water every day for all purposes.

Answer:

Bradley practice 109500 more  minutes than Jonas over the course of 2 years.

Step-by-step explanation:

Jonas practices guitar 1 hour a day for 2 years.

1 year = 365 days

2 years = [tex]365 \times 2 = 730 days[/tex]

1 hour = 60 minutes

So, Jonas practice for 60 minutes in 1 day

Jonas practice for minutes in 365 days =[tex]365 \times 60 =21900 minutes[/tex]

Bradley practices the guitar 2 hours a day more than Jonas.

So, Bradley practice the guitar for hours per day = 2+1=3 hours

3 hours = 3 \times 60 = 180 minutes

Bardley practice for minutes per day = 180 minutes

Bardley practice for minutes for 730 days = [tex]180 \times 730 =131400 minutes[/tex]

Difference in minutes in 2 years = 131400-21900=109500  minutes

Hence Bradley practice 109500 more  minutes than Jonas over the course of 2 years.

2cis33° = 2(cos33°+isin33°)

3cis22° =  3(cos22°+isin22°)

Taking tthe product of both complex numbers;

[2cis 33˚][3cis 22˚] = [2(cos33°+isin33°)][3(cos22°+isin22°)]

= 6{cos33cos22+icos33sin22+isin33cos22+i²sin33sin22}

since i² = 1

= 6{cos33cos22+icos33sin22+isin33cos22-sin33sin22}

= 6{(cos33cos22-sin33sin22)+i(cos33sin22+sin33cos22)}

Applying the trigonometric identity as shown;

cos(A+B)= cosAcosB-sinAsinB and;

sin(A+B)= sinAcosB + cosAsinB

[2cis 33˚][3cis 22˚] = 6{(cos(33+22)+ i(sin(33+22)}

[2cis 33˚][3cis 22˚] = 6(cos55°+isin55°)

[2cis 33˚][3cis 22˚] = 6cis55°

The product of the complex numbers is 6cis55°

Gimmie brainliest plzzz <3

Each pizza slice has an area of approximately 12.82 square inches, rounded to the nearest hundredth.

To find the area of each pizza slice, we first need to find the total area of the pizza and then divide it by the number of slices.

The formula for the area of a circle is [tex]\( A = \pi r^2 \)[/tex], where [tex]\( \pi \)[/tex] is approximately 3.14 and r is the radius of the circle.

Given that the radius of the pizza is 7 inches, we can calculate the total area of the pizza:

[tex]\[ A_{\text{total}} = \pi \times (7)^2 \]\[ A_{\text{total}} = 3.14 \times 49 \]\[ A_{\text{total}} \approx 153.86 \text{ square inches} \][/tex]

Now, to find the area of each pizza slice, we divide the total area by the number of slices (12):

[tex]\[ A_{\text{each slice}} = \frac{A_{\text{total}}}{12} \]\[ A_{\text{each slice}} \approx \frac{153.86}{12} \]\[ A_{\text{each slice}} \approx 12.82 \][/tex]

So, the area of each pizza slice is approximately 12.82 square inches.
