help please urgent!!!! 10 points
Answer:
[See Below]
Step-by-step explanation:
✦ First you need to know the area of a triangle:
✧ ½ x b x h
✦ Now write you formula out:
✧ ½ x 5 x 4
✦ Now just solve:
✧ 5 x 4 = 20
✧ 20 / ½ = 10
So it'd be 10 m²

What is the solution to this linear system? Enter a value in each box to create an ordered pair.
Answer:
Solution of the system will be (-3, 6).
Step-by-step explanation:
If a system of linear equations have been given in the question then we can find the solution of the linear equations by solving these equation algebraically.
But when a graph of the system of equation have been given solution of the system is the point of intersections Or common points lying on both the lines.
From the given graph,
Coordinates of the common point of both the lines is (-3, 6).
Therefore, solution of the system will be (-3, 6).
Answer: (-3, 6)
Step-by-step explanation:
you can see where the lines met

and why is it?
Answer:
4
Step-by-step explanation:
10=z+6 <subtract six to each side
4=z
Answer:
4
Step-by-step explanation:
well you got 10 = Z+6 right.. so subract 6 from 10 what do you get, you get 4 so that is th reason Z is 4

lou thinks the expression 27x^3-64 factors to (3x-4) (9x^2+12x+16). is he correct? How can you check his work? Show all work to justify your thinking.
Answer:
Step-by-step explanation:
(a³ - b³) = (a - b) (a² + ab + b²)
27x³ - 64 = 3³x³ - 4³
= (3x)³ - 4³ {a = 3x & b= 4)
Substitute in the above formula.
= (3x -4)([3x]² + 3x*4 + 4²)
= (3x - 4)(9x² + 12x + 16)
The expression 27x^3-64 factors to (3x-4) (9x^2+12x+16).

Convert 4,700,000,000 from standard form to scientific notation. 470 × 107 47 × 108 4.7 × 109 478
Answer:
4.7 * 10 ^9
Step-by-step explanation:
4,700,000,000
Scientific notation is of the form
a * 10 ^b where a is a number between 1 and less than 10
Move the decimal so that it is a number between 1 and less than 10
4,700,000,000 becomes 4.700000000 and we moved the decimal 9 places to the left b is +9 ( positive because we moved to the left) We can drop the extraneous zeros
4.7 * 10 ^9

10x + 2=32 solve for x
Answer:
X=3
Step-by-step explanation:
10x+2= 32
10x=32-2
10x=30
X=30÷10
X= 3
Answer:
x=3
Step-by-step explanation:
10x + 2 = 32
- 2 -2 (2's cancel each other out )
10x = 30 divide each side by 10 and 10s cancel out so all your left with x =3
[tex]x = 3[/tex]
Solve the right triangle. Side AB is 2.9, but I don't know how to find two missing angles with three sides and a 90-degree angle. Please explain your answer.
Angle A = 68 degrees
Angle B = 22 degrees
Side AB = 2.9 cm
The three values are approximate
=========================================================
Explanation:
a = BC = 2.7 and b = AC = 1.1 are the two legs of the right triangle.
Use the pythagorean theorem to find the length of the hypotenuse
a^2 + b^2 = c^2
2.7^2 + 1.1^2 = c^2
8.5 = c^2
c^2 = 8.5
c = sqrt(8.5)
c = 2.91547594742266
c = 2.9
The hypotenuse is c = AB = 2.9
--------------------
We then use trig ratios to find the two missing angles.
Let's say we ignore the hypotenuse and focus on the two legs of the triangle.
With respect to reference angle A, side BC is opposite and AC is adjacent
Use the tangent ratio to get
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = 2.7/1.1
tan(A) = 2.45454545454546
A = arctan(2.45454545454546)
A = 67.8336541779176
A = 68
Note: arctan is the same as inverse tangent or [tex]\tan^{-1}[/tex]. Make sure your calculator is in degree mode.
-------------------
Similarly,
tan(angle) = opposite/adjacent
tan(B) = AC/BC
tan(B) = 1.1/2.7
tan(B) = 0.4074074074074
B = arctan(0.4074074074074)
B = 22.166345822082
B = 22
Or you could use the value of A to get B = 90-A = 90-68 = 22. This works because A+B = 90 as we're working with a right triangle. In other words, A and B are complementary angles.
-------------------
In summary we found
A = 68
B = 22
AB = 2.9
BC has one endpoint
B(3,2) and a midpoint
T(6,-2). Find the
coordinates of the
other endpoint, C.
Thank you in advance!!
Answer:
Step-by-step explanation:
(3 + x)/2 = 6
3 + x = 12
x = 9
(2 + y)/2 = -2
2 + y = -4
y = -6
(9, -6) the other endpoint C
Tara is 2 years older than Ryan. The sum of their
ages is greater than 58. Describe Ryan’s age.
Ryan = 28 years
Tara = 30 years
Ryan is over 28 years old.
Step-by-step explanation:T = R + 2
T + R = 58
Replace T
(R + 2) + R = 58
2R = 56
R = 56 : 2
R = 28 years
T = 30 years

If you change the denominator for all 4 fractions, then you will get that denominator. After that you will multiply how you got that denominator from the beggining denominator. And that’s how i did it.
if a number is negative, then its opposite will be:
Answer:
the opposite of a negative number is positive.
Step-by-step explanation:
Negative numbers are numbers that are less than 0. The opposite of a positive number is negative, and the opposite of a negative number is positive. Since the opposite of 0 is 0 (which is neither positive nor negative), then 0 = 0.

Shelby purchases DVDs from a website. Each DVD costs $11, and the shipping and handling fees are $6.95. Shelby is charged a total of $50.95. How many DVDs did she purchase?
DVD cost , $11 .
Shipping and handling fees , $6.95 .
Total money charged , $50.95 .
Let , total money is T .
So,
[tex]11x+6.95=T[/tex] ( Here x is number of DVD )
[tex]11x+6.95=50.95\\\\11x=44\\\\x=4[/tex]
Therefore , total number of DVD purchased is 4 .
Hence , this is the required solution .
