A class is having a water balloon tossing contest. There is a large tub of water. Gavin uses 3 1/5 quarts of water to fill some balloons, and Quinley uses 6 1/2 quarts to fill more balloons. Find the total change of volume of water in the tub​

Answers

Answer 1

We want to find the total change in the volume of water of a tub, given that we know how much water is used.

The change in volume is: -(9 + 7/10) quarts.

To find the change in volume, we need to find the total volume of water used.

We do know that:

Gavin uses (3 + 1/5) quarts of waterQuinley uses (6 + 1/2) quarts of water.

The total amount used is the sum of the two quantities above, we get:

(3 + 1/5) quarts + (6 + 1/2) quarts

(3 + 6 + 1/2 + 1/5) quarts

(9 + 7/10) quarts.

So the change in volume is related to this, and we should write:

Final Volume - Initial Volume = -(9 + 7/10) quarts.

Where the negative sign is because at the end we have less volume than at the beginning.

What changes happened when rotate 90° counter clockwise ?

If we rotate a triangle 90° counter clockwise about the origin,

Then if one of its vertices be (x, y), it will be changed to (-y, x).

What is the required rotated vertex ?

After rotating the given triangle 90° counter-clockwise about the origin,

The vertex (-1, -1) becomes (1, -1)

The vertex (2, -1) becomes (1, 2)

So, the vertex (2, 3) will be (-3, 2)

∴ The required rotated vertices are  [tex]\left[\begin{array}{ccc}1&1&-3\\-1&2&2\end{array}\right][/tex]

What is the length of the arc by a central angle of 85 degrees and a radius of 8cm to the nearest tenth of a cm?

Answers

9514 1404 393

Answer:

  11.9 cm

Step-by-step explanation:

Arc length is given by ...

  s = rθ . . . . . . θ is the central angle in radians

Your central angle is 85°, so is (85/180)π radians = 17/36π radians.

Then the arc length is ...

  s = (8 cm)(17/36π) ≈ 11.9 cm

The length of the 85° arc is about 11.9 cm.

There are 48 students in a class and 6 of them are girls. What percent are boys

Answers

Answer:

87.5%

Step-by-step explanation:

If there are 48 students in total and 6 girls, then the remaining students are  boys

The number of boys = 48 - 6 = 42

Now, calculate the %

42/48 x 100 = 7/8 x 100 = 87.5%

Hope this helps

If there are 48 students in a class and 6 of them are girls then the percentage of boys in the class is 87.5%,

Use the concept of percentage defined as:

A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.

The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

Given that,

Number of students = 48

Number of girls = 6

Then number of boys = 48 - 6

The number of boys = 42

Therefore,

The percentage of boys in the class is,

[tex]\dfrac{42}{48}\times 100= 87.5 \text{ percent}[/tex]

Hence,

There are 87.5 percent of boys in the class.

Find the maximum walking speed of a coyote with legs 0.46 m long. How much faster can a giraffe walk than a coyote?

Answers

Answer:

7.03 ft/s

Step-by-step explanation:

To obtain speed using the model :

Speed = sqrt(gL)

L = Length of leg, g = acceleration due to gravity

Length of leg of a giraffe = 6.03

g = 9.8 m/s or 32 ft/s²

Speed of giraffe in ft/s = sqrt(32 * 6.03) = 13.89 ft/ s

Speed of coyote ; L = 0.46 m

L in feets = 0.46 * 3.23 = 1.4858 feets

s = sqrt(1.4858 * 32) = 6.895 ft/s = 6.86 ft/s

Difference in speed :

13.89 - 6.86 = 7.03 ft/s

Giraffe has 7.03ft/s more speed Than a coyote

Crumple zones in the engine compartment and air bags are two examples of safety technology designed to protect driver and passengers involved in a collision. How do these design features impact the formula above and the force of impact? They decrease the force of impact by providing a cushion during the impact. Smaller force = lower momentum. They decrease the force of impact by extending the time it takes to stop the driver and passenger. Longer time = less force. It takes a longer time for the velocity of the vehicle to decrease, therefore the force is less. Decrease in velocity = less force. When a car rebounds it undergoes a greater change in velocity and the force is decreased. Lower force = greater change in velocity. What is the length of HE PLS HELP URGENT!!!!!!
