Expand the expression 3(5p+1) using the distribution property




PLEASE HELP

Answers

Answer:

15p + 3

Step-by-step explanation:

Multiply 3 by each number in the parentheses and keep the variable

Using the distribution property 3(5p + 1) is  15p + 3.

What are the basic properties of arithmetic laws of operations?

There are three types of basic arithmetic laws of operation.

Commutative law for addition and multiplication states,

a + b = b + a.

a×b = b×a.

Distributive law states,

a(b ± c) = ab ± ac.

Associative law states,

a + (b + c) = (a + b) + c.

Given, An expression 3(5p + 1).

=  3×5p + 3×1.

= 15p + 3.

How are convection currents in the mantle (geosphere) and in the oceans (hydrosphere) similar? Or how are they different. Explain one of the two or how their similar and different. Thanks :)
I give brainliest to whichever makes the most sense

Answers

Answer:

They are different because in the mantle, the magma is heated, it becomes less dense and rises. It give off it's thermal energy and cools down, becoming more dense and descend to be heated again.

In the ocean, the tropics warm the water and it travels to the poles to cool down, then returns to the tropics to heat up again.

they are similar in the ways that they move and create energy.

Hello!

A function will be increasing if the y values are increasing (since this is a function, this will pass the vertical line test, meaning that it is increasing if the y values are increasing).

On interval 1, the function is not increasing since the y value stays constant.

On interval 2, the function is increasing because the y values are increasing.

On interval 3, the function decreases because the y values are decreasing.

On interval 4, the function increases again.

On interval 5, the function stays the same because of its constant y value.

To reiterate, on intervals 2 and 4, the function is increasing.

A rectangular barn measuring 14 feet b 10 feet is located in one corder of a fenced area. Robert ties his cow to the corner of the barn so the animal can graze anywhere within the circular area outside the barn and fence. If the cow is tied with a 24 ft rope, approximately how much grazing area does the cow have?

Answers

For this problem you would be solving for the area of 3/4 of a circle with the radius being 24ft. So area of a circle is a= PI R squared so plug in 3.14(24)squared order of operations says to square first so 24 squared is 576. Then PI or 3.14 times 576 equals 1808.64
Now because it is only 3/4 of a circle you wil multiply the answer by 3/4 which is 1,356.48 ft. So the Cow has 1,356.48 Ft of grazing area.

If when the cow is tied with a 24 ft rope, So approximately, The Cow has 1,356.48 Ft of grazing area.

Calculation of Circular area

For this situation, you would be translating for the area of 3/4 of a circle with the radius being 24ft.

So the area of a circle is a is = PI R squared so plugin 3.14(24) squared order of functions says to square first so 24 squared is 576.

Then PI or 3.14 times 576 equals 1808.64

Now because it is exclusively 3/4 of a circle you will reproduce the response by 3/4 which is 1,356.48 ft.

Therefore, The Cow has 1,356.48 Ft of grazing area.

Consider the data below.

2, 2, 2, 3, 5, 6, 8, 30

The mean decreases by ? when the outlier is removed.

Answers

Answer:

It is decreased by 3.25

Step-by-step explanation:

When you add all 8 numbers you'll get 58 then you divide them by 8 you will get 7.25 which is the mean. To find out what is the decrease we need to take out the 30 and add all the other numbers and we get 28. After that you divide 28 by 7 and you get 4. Subtract 4 from 7.25 and you get 3.25.

2+2+2+3+5+6+8+30=58

58/8=7.25

2+2+2+3+5+6+8=28

28/7 = 4

7.25-4=3.25
