Answer:
A = 28.26 cm², P = 38 units, A = 20 units², C = 43.96 units
Step-by-step explanation:
1) Our area of a circle is πr². Since our r = 3 cm, we can just substitute for r.
A = πr²
A = (3.14)(3)²
A = (3.14)(9)
A = 28.26 cm², like in your work.
2) Our formula for perimeter is 2l + 2w. We substitute for l = 12 and w = 7.
P = 2l + 2w
P = 2(12) + 2(7)
P = 24 + 14
P = 38 units
3) The formula for a triangle's area is A = [tex]\frac{1}{2}[/tex]bh, so we substitute for b = 10 and h = 4.
A = [tex]\frac{1}{2}[/tex] bh
A = [tex]\frac{1}{2}[/tex] (10)(4)
A = [tex]\frac{1}{2}[/tex] (40)
A = 20 units²
4) Circumference is 2πr, and we substitute for r = 7.
C = 2πr
C = 2(3.14)(7)
C = (3.14)(14)
C = 43.96 units

Luis, que recibe $200 mensuales desde hace un año, el mes pasado le dijo a su papá que le aumentará su mesada; el monto deseado será suficiente si tres medios de la cantidad deseada más 4100 son mayores o iguales a $700. ¿Cuánto de más quiere recibir Luis?
Answer:
Luis quiere recibir 200$ de más por mes.
Step-by-step explanation:
Para podr calcular esto, necesitamos escribir la desigualdad dada, y para ello debemos transformar el lenguaje a lenguaje algebraico.
tres medios de la cantidad deseada: 3/2 x
mas 4100 (en este caso debería ser $100, y fue un error de tipeo): + 100
son mayor o igual a $700: ≥ 700
Inecuación: 3/2 x + 100 ≥ 700
Ahora solo nos queda resolver el valor de x de esta inecuación. El resultado nos dirá cuanto quiere recibir al mes, por lo que la resta de esta cantidad con la cantidad que recibía antes nos dirá cuanto de más desea recibir:
3/2 x + 100 ≥ 700
3/2 x ≥ 700 - 100
3/2 x ≥ 600
3x ≥ 600 * 2
x ≥ 1200 / 3
x ≥ 400
Por tanto, Luis desea recibir al mes $400, lo que se traduce en que quiere recibir de más
400 - 200 = 200
Luis desea recibir de mas $200.
Espero te ayude

Unit 4 Homework 2 Gina Wilson all things algebra,
Pls help!
Answer:
1. m∠1 = 48°
2. m∠1 = 129°
3. m∠1 = 37°
4. m∠1 = 88°
m∠2 = 42°
m∠3 = 113°
5. m∠1 = 72°
m∠2 = 35°
m∠3 = 24°
6. m∠1 = 128°
m∠2 = 52°
m∠3 = 47°
m∠4 = 133°
m∠5 = 81°
7. m∠1 = 41°
m∠2 = 85°
m∠3 = 95°
m∠4 = 85°
m∠5 = 36°
m∠6 = 49°
m∠7 = 106°
8. x = 12°
9. x = 9°
10. x = 5°
11. x = 7°
Step-by-step explanation:
1. 76° + 56° + m∠1 = 180°
∴ m∠1 = 180° - (76° + 56°) = 48°
m∠1 = 48°
2. m∠1 = 67° + 62° = 129°
m∠1 = 129°
3. m∠1 = 152° - 115° = 37°
m∠1 = 37°
4. m∠1 = 180° - (52° + 42°) = 88°
m∠1 = 88°
m∠2 = 42°
m∠3 = 180 - (42° + 25°) = 113°
m∠3 = 113°
5. m∠1 = 180° - 118° = 72°
m∠1 = 72°
m∠2 = 180° - 72° - 73° = 35°
m∠2 = 35°
m∠3 = 73° - 49° = 24°
m∠3 = 24°
6. m∠5 = 180° - m∠52° - m∠47° = 81°
m∠5 = 81°
m∠1 = 81° + 47° = 128°
m∠1 = 128°
m∠2 = 52°
m∠3 = 47°
m∠4 = 180° - 47° = 133°
m∠4 = 133°
7. m∠3 = 95°
m∠5 = 180° - 144° = 36°
m∠5 = 36°
m∠6 = 180° - 95° - 36° = 49°
m∠6 = 49°
m∠4 = 180° - 95° = 85°
m∠4 = 85°
m∠2 = 85°
m∠7 = 360° - (38° + 85° + (180° - 49°)) = 106°
m∠7 = 106°
m∠1 = 360° - (85° + 90° + 144°) = 41°
m∠1 = 41°
8. (10·x - 11)° + (3·x - 2)° + (3·x + 1)° = 16·x° - 12° = 180°
16·x = 180°+ 12° = 192°
x° = 192°/16 = 12°
x = 12°
9. (3·x - 5)° + (7·x + 5)° + 90 = 180°
10·x + 90° = 180°
10·x = 180°- 90° = 90°
10·x = 90°
x = 90°/10 = 9°
x = 9°
10. 180 - 151 = 29°
(11·x - 1)° + (20·x - 3)° + 29° = 180°
31·x° + 25° = 180°
31·x° = 180° - 25° = 155°
31·x° = 155°
x = 155/31 = 5°
x = 5°
12. (4·x + 13) + (6·x + 2) + 180 - (14·x - 13)
208° - 4·x° = 180°
208° - 180° = 4·x°
28° = 4·x°
4·x° = 28°
x = 28°/4 = 7°
x = 7°.

Why might algebra tiles not be a good tool to use to factor x2 + 18x + 80? Explain.
Step-by-step explanation:
Algebra tiles would not be a good tool to use to factor the trinomial because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles. That is a total of 99 tiles. It would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. You would also need to determine how to arrange all those tiles to make a rectangle. Since 80 is a multiple of 10, you might recognize that 10 and 8 are the factors that add to 18, which would give you the values to use in the X method.
There are a lot of tiles to drag onto the board.
You would need to create a rectangle from 99 tiles.
80 is a multiple of 10, so it has factors of 10 and 8, which add to 18.

Actually Welcome to the Concept of the Functions.
Since, the above function is a square root function, we must always keep it's domain as Positive Real numbers, such that it will not went to the imaginary axis, hence
D: R+
Range, for range we equate it to 0 ,
hence we get as,
R: x belong from 0 to positive Infinite
As, x---> infinite, f(x) ---> - infinite
As, x----> 0 , f(x) -----> 0
increasing interval, we have to differentiate it, we get as
-4 to 0
Decreasing interval is 0 to infinite
Solve two fifths minus one seventh equals blank.
Answer:
9/35.............,..........
Answer:
1/5
Step-by-step explanation:
2/5 - 1/7 = ???
find the least common denominator!
45 would be the least common demoninator!
so...
2 (7) / 5(7) - 1 (5) / 7 (5) = ?
14/ 45 - 5 /45 = ?
14 - 5 = 9
9/45. Simplify!
9/45 divide 9 from both sides
9/9 / 45/9
= 1/5, one fifths is your answer!

[tex]m= 14 \sqrt 2, \: n = 14[/tex]
Step-by-step explanation:
Hope it helps you in your learning process.
Given is a 45°-45°-90° triangle.
Measure of sides n and 14 are opposite to 45° degree angles.
Therefore, they are equal.
So, n = 14

can you please show work for 5x/9=x/6+7
Step-by-step explanation:
Please refer to the attachment
Answer:
x = 18
Step-by-step explanation:
5x/9 = x/6 + 7
multiply both sides by 9
5x = 9x/6 + 63
multiply both sides by 6
30x = 9x + 378
subtract 9x from each side
21x = 378
divide both sides by 21
x = 18
check by substituting 18 for x:
5(18)/9 = 18/6 + 7
5(2) = 3 + 7
10 = 10
