Seven and thirty twp hundreths plus two and one tenth times two and seven tenths minus 18a

Answers

Answer 1

Answer: Answer: Write the expression as:

" 70 $(32)/(100)$ +
2 $(1)/(10)$ * 2 $\frac{7}{10$ − 18a " ;
______________________________________________________
or; write as:
______________________________________________________
" 70.32 + (2.1) * (2.7) − 18a " ;
______________________________________________________

To simplify:
______________________________________________________

Using "PEDMAS" (the "order of operations") ;

the "multiplication" comes first;

So: → "(2.1) * (2.7) = 5.67 " .

And rewrite:
______________________________________________________
" 70.32 + 5.67 − 18a " .

Now: " 70.32 + 5.67 = 75.99 " ;

So, we can the final simplified expression as:
______________________________________________________
" 75.99 − 18a " ;

or; write as: " 75 $(99)/(100)$ − 18a " .
______________________________________________________

PLS HELP!!!

Answers

Answer:

y=7x+1

Step-by-step explanation:

Linear modeling

Consists of finding a linear equation that represents a situation in real life.

Jenny starts her stamps collection with only 1 stamp.

Then she collects 7 stamps per day.

Let's call

y=total amount of stamps in Jenny's collection

x=number of days

Knowing Jenny collects 7 stamps per day, then in x days, she collects 7x stamps. The total amount can be obtained by adding the first stamp she had. Thus, the model is:

y=7x+1

Answer:

Was it correct??? y=7x+1 is that correct or wrong?

What is the volume of the cone below

Answers

Answer:

263.99Pi or 264Pi units by approximation

Step-by-step explanation:

Volume of cone is 1/3 x Pi x radius ^2 x height

Radius is given as 6, height as 22

Hence volume of cone= 1/3 x Pi x (6)^2 x 22

=1/3 x PI x36x 22

= 263.99 PI

=264PI units

Gregg has 12 cards. Half are black, and half are red. He picks two cards out of the deck. What is the probability that both cards are red

Answers

The solution is, the probability that both cards are red is 5/22.

What is probability?

Probability can be defined as the ratio of the number of favorableoutcomes to the total number of outcomes of an event.

here, we have,

given that,

Gregg has 12 cards.

Half are black, and half are red.

i.e. red = 6 & black = 6.

He picks two cards out of the deck.

now, we have,

Probability of a red card out of 12 cards = 6/12 = 1/2

Now, probability of a red card of 11 cards = 5/11

so, we get,

Combined probability = 1/2 * 5/11 = 5/22

Hence, The solution is, the probability that both cards are red is 5/22.

Probability of a red card out of 12 cards = 6/12 = 1/2
Now, probability of a red card of 11 cards = 5/11

Combined probability = 1/2 * 5/11 = 5/22

In short, Your Answer would be 5/22

I enter the garden. There are 34 people. You hug 30. How many people are in the garden.

Answers

There are 34 people in the garden prior to the time I joined them.

So when I entered the garden, the total number of people in the garden will be:

34 + 1 = 35 people

Let assume, you as the reader was part of the people in the garden and you hugged 30 people. That doesn't add up or increase the number of people in the garden.

At the end of the day, the number of people you did not hug is:

35 - 30 - 1(you)

= 35 - 31

= 4 people

Therefore, we can conclude that there are 35 peoplepresent in the garden.

Step-by-step explanation:

The area of a trapezoid is given by the formula A=h/2(a+b) .

Solve the formula for b.

Answers

Answer:

(2A)/h -a =b

Step-by-step explanation:

A= [h(a+b)]/2 I rewrote the formula, because h and a+b are in the numerator.

2A=h(a+b) Multiply both sides of equation by 2

(2A)/h= a+b Divide both side by h

(2A)/h -a= b Subtract a from both sides
