Why do you think triangles and math are important and bridges you must use proper math terms and provide your reason as wide tri

Makovka662 [10]

Well, from triangles we derive trigonometry which can be use to construct bridges, for example, if we want to construct a bridge using some kind of support belief it, it’ll probably be a triangular structure cause it supports more stability

How to write the algebraic expression (2)(t) in words

Jlenok [28]

Answer:

"The number 8 multiplied by a number. "

"The product of 8 and a number"

"A number times the number 8"

Step-by-step explanation:

This is a long one,

You are going to write the expression using "key words"

Addition: sum, more than, plus, increase, add, older than.

Examples: 4+7

"The sum of 4 and 7"

"7 more than the number 4"

"The number 4 increased by 7"

Etc....

Subtraction: minus, less, subtract, decrease, younger than, and lowered.

Example: 9 - 2

"The number 9 decreased by 2"

"The number 2 younger than 7"

"The number 7 minus 2"

Etc....

Multiplication: times, product, twice, doubled, multiplied, and of.

Example: 4 × 5

"The number 4 multiplied by 5"

"The product of the numbers 4 and 5"

"5 times the number 4"

Etc...

Division: divided by and divided into and Quotient. Pay close attention to the order in which it is written.

Examples: 6 / 3

"The number 6 divided by 3"

"3 divided into the number 6"

Or

"The quotient of the numbers 3 into 6"

Ect...

Expressions with More Than One Operation example:

8y + 14 ...

You could say:

The sum of 8 times a number and 14.

When referring to unknown number i.e. x, y, n, v... you may refer to it a "a number"

Hmmm, best way I can describe it. :)

A turkey costs $1.05 per pound. There are going to be fifteen people at Thanksgiving dinner. Plan for each person to eat two, 3/

valina [46]

Answer:

<em>I will need to buy 22.5 pounds of turkey and pay $23.63</em>

Step-by-step explanation:

<u>Proportions</u>

Each person is planned to eat 2 x 3/8 pound servings of turkey for thanksgiving dinner. This means each person will eat

$2\cdot\frac{3}{4}=\frac{3}{2}$

pounds of turkey.

There are going to be 15 people at the dinner, thus the total turkey needed is:

$15\cdot\frac{3}{2}=22.5~pounds$

The turkey costs $1.05 per pound, thus the total cost is

22.5*$1.05 = $23.63

I will need to buy 22.5 pounds of turkey and pay $23.63

Factor quadratic trinomials

ad-work [718]

1. (x - 9) + (x + 5)
You split the x^2 into two xs
The one with an x (-4x) is what the two numbers should equal
-9 + 5 = 4
The one without an x (-45) is what the two numbers product should be
-9 times 5 = -45
*so remember the x is the sum of the two
*no x is the product of the two
Theres no quick trick to find the answer u just have to plug it in
*start with all the numbers that multiply for the no x (-45)
-3 and 15 or 3 and -15 is obviously not it as the sum does not equal -4
Those sums equal 12 or -12
I’ll do one more and ur on ur own comrade (ok and ill do number 4)
3. (x - 8) + (x - 9)
ok this time both the answers have a negative
*if it has only one negative in the problem there are going to be TWO negatives in the answer
-8 and -9 sum is -17
-8 and -9 sum is 72
If there was only one negative in the answer it would make the 72 negative and there is no -72 in the problem
So this one is
(x - 8) + (x - 9) (u dont have to have it like this u can put the (x - 9) in the front doesn’t matter which way it’s just the signs (- & +) that matter
OK now 4.
4. This one is very easy as all u need to do is find the two numbers for the product
(X - 6) (X + 6)
(Again it doesn’t matter which () is in front just the SIGNS INSIDE THE PARENTHESES ( + & - )
