The average person blink 15 to 20 times per minute how many times does the average person blink in an hour

Answer:

  KE = 100 J

Step-by-step explanation:

The question is asking you to use the formula with the values ...

  m = 8 kg . . . . . this 'm' stands for mass

  v = 5 m/s . . . .  this 'm' stands for meters

Putting these values into the formula, we have ...

  KE = 1/2(8 kg)(5 m/s)² = 100 kg·m²/s²

The units are equivalent to the derived SI unit "joules", abbreviated J.

The kinetic energy of the 8 kg mass is 100 J.

Answer:

x= 116/17

Step-by-step explanation:

5x+192−321+13=−12x

Step 1: Simplify both sides of the equation.

5x+192−321+13=−12x

5x+192+−321+13=−12x

(5x)+(192+−321+13)=−12x(Combine Like Terms)

5x+−116=−12x

5x−116=−12x

Step 2: Add 12x to both sides.

5x−116+12x=−12x+12x

17x−116=0

Step 3: Add 116 to both sides.

17x−116+116=0+116

17x=116

Step 4: Divide both sides by 17.

17x/17=116/17

x = 116/17

Answer:

W = 1.8 kg

Step-by-step explanation:

Zoé bought 3 cheeses, 3/5 each. How many Kilograms of cheese does he have in total?

Weight of each cheese is 3/5 kg. Zoe bought 3 cheeses. We need to find the weight of cheese in total.

To find weight of 3 cheeses, we will multiply 3 by 3/5 such that:

[tex]W=3\times \dfrac{3}{5}\\\\W=1.8\ kg[/tex]

So, the weight of cheese in total is 1.8 kg.

Step-by-step explanation:

Considering the given matrix, it is found that the number of solutions of the system of equations is given by:

B. 1.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

The matrix form of the system can also be written as:

[tex]\left[\begin{array}{cc}1&0\\0&1\end{array}\right]\left[\begin{array}{c}x\\y\end{array}\right] =  \left[\begin{array}{c}5\\6\end{array}\right][/tex]

Applying the multiplication of the matrices, we have that:

Step-by-step explanation:

Since ten cups of ice cream is made from .5 cups of sugar, lets first find out how many cups of ice cream can be made form one cup of sugar

.5*2=1

10*2=20

Since the ratio of sugar to ice scream is .5/10 if you do anything to the top you need to do it to the bottom

so now you have 1/20

for every one cup of sugar there are 20 cups of icecream

now you need to multiply both top and bottom by five

1*5=5

20*5=100

5/100

You can make 100 cups of ice cream

*don't forget to label your answer with cups of ice cream*

100 cups of ice cream can be made with 5 cups of sugar.

Comparing quantities is the qualitative relation between two quantities which reflects the relative size of both the quantities.

It is given that,

10 cups of ice cream requires = 0.5 cup of sugar

⇒ 1 cup of sugar = 10/0.5 cups of ice cream

⇒ 1 cup of sugar = 20 cups of ice cream

Hence we see that Maya's ice cream machine makes 20 cups of ice cream from 1 cup of sugar.

Similarly, 5 cups of sugar = 5 x 20 cups of ice cream

⇒ 5 cups of sugar = 100 cups of ice cream

Therefore,100 cups of ice cream can be made with 5 cups of sugar.

Given the following information:

First three hours of typhoon: rate of Rainfall. = 25mm per hour

Typhoon slows down for an hour : then Rainfall began again at a constant rate of 20 mm per hour for the next 2 hours

Piecewise function which models Rainfall ad a function of time

Amount of Rainfall as a function of time = f(t)

f(t) = 25t ; if t≤ 3

When typhoon slowed down for an hour :

f(t) = 0;

f(t) = 25*3 ; for t ∈ (3, 4)

Then Rainfall at a constant rate of 20mm for another 2 hours

f(t) = (25 *3) + 20(t - 4) ; for t ∈ (5, 6)

[tex]\frac{1}{3} x-\frac{2}{3} =-18[/tex]

Add [tex]\frac{2}{3}[/tex] to both sides of the equation:

[tex]\frac{1}{3} x=-18 +\frac{2}{3}[/tex]

Simplify [tex]-18+\frac{2}{3}[/tex] by multiplying [tex]-18[/tex] in fraction form [tex]-\frac{18}{1}[/tex] to get a common denominator so you can add the two fractions:

[tex]-\frac{18}{1}[/tex] × [tex]\frac{3}{3}=-\frac{54}{3}[/tex]

Now add the two fractions:

[tex]-\frac{54}{3} +\frac{2}{3} =-\frac{52}{3}[/tex]

Now write the simplified equation:

[tex]\frac{1}{3} x=-\frac{52}{3}[/tex]

Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]\frac{1}{3}[/tex]:

[tex]x=-\frac{52}{3}[/tex] ÷ [tex]\frac{1}{3}[/tex]

Use the reciprocal of the dividend ([tex]\frac{1}{3}[/tex]), and multiply by your divisor:

[tex]x=-\frac{52}{3}[/tex] × [tex]\frac{3}{1}[/tex]

[tex]x=-\frac{156}{3}[/tex]

Simplify the fraction by dividing [tex]-156[/tex] into [tex]3[/tex]:

[tex]x=-52[/tex]

The number of different license plates that can be made in Idaho with 4 numbers followed by 2 letters is 6,760,000, option a is correct.

To determine the number of different license plates that can be made in Idaho with 4 numbers followed by 2 letters, we need to consider the possibilities for each element.

For the numbers, we have 10 options (0-9) for each of the four positions, resulting in a total of [tex]10^4 = 10,000[/tex] combinations.

For the letters, we have 26 options (A-Z) for each of the two positions, resulting in a total of [tex]26^2 = 676[/tex] combinations.

To find the total number of different plates, we multiply the number of possibilities for each element:

[tex]10,000 \times 676 = 6,760,000[/tex].
