Answer:

a. 1 dag

Step-by-step explanation:

The list of SI prefixes is attached. Each has an abbreviation that can be used with the abbreviation for the SI unit of interest.

<h3>Application</h3>

A factor of 10 is signified by the prefix deka-, abbreviated "da". Then 10 grams is 1 dekagram, or 1 dag.

Solve y – 7 > 3 + 2y A) y -10 D) y > -10

Anika [276]

Answer:

D. $-y > 10$

Step-by-step explanation:

First, move the variable (+ 2y) to the left-hand side and change its sign.

$y - 2y - 7 > 3$

Then, move the constant (+ 7) to the right-hand side and change its sign.

$y - 2y > 3 + 7$

Then, collect the like terms (y - 2y)

$-y > 3 + 7$

Finally, add the numbers (3 + 7). That will get you your final answer.

$-y > 10$

the NACI cafeteria wants to sell two 25 cm diameter medium size pizzas for the same price as one large pizza. what should the di

Alex777 [14]

Answer:

35.34 centimeters

Step-by-step explanation:

The amount of pizza is same as the area. The pizza is in a shape of a circle. The area of a circle is:

$A=\pi r^2$

Where

r is the radius (half of diameter)

Area of one medium size pizza is (diameter 25 means radius is 25/2 = 12.5):

$A=\pi r^2\\A=\pi (12.5)^2\\A=490.87$

So, area of two of these medium size pizzas is:

490.87 * 2 = 981.74

This should be the area of the large pizza. We can find the radius of that by substituting into formula. Shown below:

$A=\pi r^2\\981.75=\pi r^2\\r=\sqrt{\frac{981.74}{\pi}} \\r=17.67$

Hence, the diameter would be around:

17.67 * 2 = 35.34 centimeters

Suppose the variable x is represented by a standard normal distribution. What is the probability of x > 0.3 ? Please specify

uysha [10]

Answer: 0.38

Step-by-step explanation:

Since the variable x is represented by a standard normal distribution, the probability of x > 0.3 will be calculated thus:

P(x > 0.3)

Then, we will use a standard normal table

P(z > 0.3)

= 1 - p(z < 0.3)

= 1 - 0.62

= 0.38

Therefore, p(x > 0.3) = 0.38

The probability of x > 0.3 is 0.38.

How do you get why by itself in this equation? 4x+5y=5

Alja [10]

Answer:

first we get y on one side by itself.

4x+5y=5

we'll move x to the other side.

4x-4x+5y=5-4x

simplify.

5y=5-4x

now we get rid of the coefficient on y.

5y/5=(5-4x)/5

simplify.

y=5/5-4x/5

y=1- $\frac{4}{5}x$

The answer is $y=1-\frac{4}{5}x$
