Triangle inequality
Answer:
DF
EF
DE
Step-by-step explanation:
First, we need to figure out the third angle.
Angles in a triangle add up to 180, so
180 = 61 + 59 + DEF
DEF = 180 - (61 + 59) = 180 - 120 = 60
In a triangle, the smallest angle is always opposite the shortest side, and the largest angle opposite the longest.
The three angles are 61, 60, and 59.
Since DEF(61) is the largest, DF is the longest.
Next is EDF(60), so EF is the next.
Finally, DFE(59) is the smallest angle, so DE is the shortest.
DF, EF, DE
What is the sum of x^2 - 3x + 7 and 3x^2 + 5x - 9
Hey there!
The answer to your question is [tex]4x^2+2x-2[/tex]
Given:
[tex]x^2-3x+7[/tex] [tex]and[/tex] [tex]3x^2 +5x-9[/tex]
First, we can start by adding like terms. The following are like terms:
[tex]x^2[/tex] [tex]and[/tex] [tex]3x^2[/tex]
[tex]-3x[/tex] [tex]and[/tex] [tex]5x[/tex]
[tex]7[/tex] [tex]and[/tex] [tex]-9[/tex]
Now, we can add these pairs together, giving us:
[tex]4x^2[/tex]
[tex]2x[/tex]
[tex]-2[/tex]
Now, add all this together, and we get our answer as:
[tex]4x^2 + 2x - 2[/tex]

The proportion is given by the equation c = pg where the value of p is
p = 0.75
What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as p
Now , the equation will be
Jaiden mixed 6 cups chocolate chips with 8 cups of granola to make trail mix
So , for 6 cups chocolate chips = p x 8 cups of granola
So , the proportion will be
Substituting the values in the equation , we get
6 = p x 8
Divide by 8 on both sides of the equation , we get
p = 6/8
On simplifying the equation , we get
p = 0.75
Therefore , the value of p is 0.75
Hence , the proportion equation is c = 0.75g

A farmer has just tilled her 51-yard by 68-yard field. To survey her field, the farmer begins in one corner and walks the length of the field. She then turns and walks the width before crossing diagonally across the field to the original corner. How far does the farmer walk?
Answer: l +w+ hypotenuse or 204
Step-by-step explanation: so the farmer walks the length then the width of the field then the diagonal which we don't know using pythagorean to find that last side then add the values 51^2+68^2=c^2 and 51+68+85= 204

Round to the nearest thousand. 6,159
Answer:
6,000
Step-by-step explanation:
To round to the nearest thousand, you keep the digit in the thousands and round up or down, clearing all other smaller units. You round up when the next largest digit, in this case, the hundreds, is 5 or larger. Meanwhile, you round down when it is 4 or smaller. Here it is 1, so you round down to 6,000. If it was 5 or larger, you would round up to 7,000.
6,000
To round a number we look at the number that is right of the one we are rounding. If the number to the left is 4 or under, you round down. If it's 5 or above, you round up.

(b) A square has an area of 9 cm? What is the length of each side?
Answer:
Each side would have the length of 3.
Step-by-step explanation:
In order to find the area of something you have to multiply the side length and 3 x 3 equals 9.
Answer: The length of each side is 3cm
Step-by-step explanation:
The formula for finding the area of a square is A=a²
-------------------------------------------------------------------------------
Given
The Area is 9 cm
Formula
A=a²
Substitute the value into the formula
A=a²
9=a²
a=√9
a=3
(The reason why it is not ±3 is that length cannot be negative)
