Answer:
2 months
Step-by-step explanation:
The selling price of the sweater = 0.5 x $20 = $30
For every month that the sweater doesn't sell, price is reduced by 20% = 0.2 x $30 = $6
After the first month, price is reduced by $30 - $6 = $24
After the second month, price is reduced by $24 - $6 = $18

Consider the rule y = 5x + 7.
a. How many tiles are in Figure 0?
b. Which figure has 37 tiles?
c. In the equation y = mx + b, what do the letters m and b represent?
Answer:
see below
Step-by-step explanation:
Consider the rule y = 5x + 7.
a. How many tiles are in Figure 0?
In figure 0, we let x=0
y = 5*0+7 = 0+7 = 7
b. Which figure has 37 tiles?
This means y = 37
37 = 5x+7
Subtract 7 from each side
37-7 = 5x+7-7
30 = 5x
Divide by 5
30/5 = 5x/5
6 =x
Figure 6 has 37 tiles
c. In the equation y = mx + b, what do the letters m and b represent?
m is the slope or how much it is increasing each time x increases by 1 and b is how much we start with when x =0

If a = 15 and c. 25 what is the length of leg b of a right triangle using the
pythagorean theorem?
Answer:
b=20
Step-by-step explanation:
[tex]b ^{2} + {a}^{2} = {c}^{2} \ \\ {b}^{2} = {c}^{2} - {a}^{2} \\ {b}^{2} = {25}^{2} - {15}^{2} = 625 - 225 = 400 \\ b = \sqrt{400} = 20[/tex]
Given : In a triangle ABC , a = 15 , c = 25 . Also the triangle is a right angled triangle .
To Find : The value of b using the Pythagoras Theorem.
Solution : The value of side a is 15 , c is 25 and we have to find b . The sides with be Pythagorean Triplet whose smallest member will be 15 . So the third member. will be 20 . And the largest member is 25 .
The Pythagoras Theorem is :
[tex]\boxed{\red{\bf hypontenuse^2=base^2+perpendicular^2}}[/tex]
⇒ c² = a² + b² .
⇒ b² = c² - a² .
⇒ b² = ( c + a ) ( c - a ) .
⇒ b² = ( 25 + 15 ) ( 25 - 15 ) .
⇒ b² = 40 × 10.
⇒ b² = 400.
⇒ b² = √400.
⇒ b = 20 .
Hence the value of c is 20 .
If f(x) = 10x + 3 what is the value of x when f(x) =19
Answer:
x = 1/ 10 y + −3 /10
Step-by-step explanation:
Let's solve for x.
y = 10x + 3
Step 1: Flip the equation.
10x + 3 = y
Step 2: Add -3 to both sides.
10x + 3 + −3 = y + −3
10x = y −3
Step 3: Divide both sides by 10.
10/10x = y −3/ 10
x = 1 /10 y + −3 /10
Therefore the answer is
x = 1/ 10 y + −3 /10

Angles R and S are complementary. The measure of angle R equals 35 degrees.
What is the measure of angle S ?
Answer:
55 degrees
Step-by-step explanation:
I hope this helps, all you need to do is subtract 90 from 35 and your answer is S in which 55 degrees.
Answer: 55°
Step-by-step explanation:
complementary means the angles make up an angle of 90°, therefore to find the missing angle you do, 90-35 which equals 55

100^(3-4x)/(2x+1) is less than or equal to 0.01^(5x-8)/(2x+1)
Answer:
domain: 2x+1 not equal to zero, then x not equal to -1/2
Set 2x+1>0
then x>-1/2
100^(3-4x)/(2x+1)<=0.01^(5x-8)/(2x+1)
100^(3-4x)<=0.01^(5x-8)
(10^2)^(3-4x)<=[10^(-2)]^(5x-8)
10^[2*(3-4x)]<=10^[(-2)*(5x-8)]
10^(6-8x)<=10^(16-10x)
6-8x<=16-10x
2x<=10
x<=5
combine x>-1/2 and x<=5
then - 1/2<x<=5
Set 2x+1<0
then x<-1/2
100^(3-4x)/(2x+1)<=0.01^(5x-8)/(2x+1)
100^(3-4x)>=0.01^(5x-8)
(10^2)^(3-4x)>=[10^(-2)]^(5x-8)
10^[2*(3-4x)]>=10^[(-2)*(5x-8)]
10^(6-8x)>=10^(16-10x)
6-8x>=16-10x
2x>=10
x>=5
combine x<-1/2 and x>=5
, then x does not exist while 2x+1<0
so answer is - 1/2<x<=5

7-5(x+6)= -7x-17 what value of x makes the equation true?
Answer:
x=3
Step-by-step explanation:
7-5(x+6)= -7x-17
Distribute
7 - 5x-30 = -7x-17
Combine like terms
-5x-23= -7x-17
Add 7x to each side
-5x-23+7x= -7x-17+7x
2x -23 = -17
Add 23 to each side
2x-23+23 = -17+23
2x= 6
Divide by 2
2x/2 = 6/2
x =3
Answer:
x = 3
Step-by-step explanation:
7 - 5(x + 6) = -7x - 17
~Simplify left side
7 - 5x - 30 = -7x - 17
~Combine like terms
-5x - 23 = -7x - 17
~Add 23 to both sides
-5x = -7x + 6
~Add 7x to both sides
2x = 6
~Divide 2 to both sides
x = 3

3 times Marie’s age is equal to 50 plz show work
Answer:
m = 16 2/3
Step-by-step explanation:
Let m = maries age
3m = 50
Divide by 3
3m/3 = 50/3
m = 16 2/3
Answer:
Marie's age is 16.7 years
Step-by-step explanation:
3 times Marie's age is equal to 50, so you divide 50 by 3.
50 ÷ 3 = 16.6666666 repeating, round it to 16.7
Marie's age is 16.7 years.
Check: 3 x 16.7 = 50.1 so you round it to 50.
Hope this helps!

Para recortar algumas figuras geométricas, um aluno utilizou uma cartolina com 1mx0,8m. Sabendo que ele recortou 2 triângulos, ambos com 20cm de base e 30 cm de altura, 2 trapézios ambos com bases de 10cm e 20cm e altura de 7cm. Determine em cm² quanto foi a área da cartolina que sobrou. * 1 ponto 7595cm² 0,7595m² 7190cm² 0.719m²
Answer:
7190 cm²
Step-by-step explanation:
Para recortar algumas figuras geométricas, um aluno utilizou uma cartolina de 1 m x 0,8m.
Passo 1
Determine a área de todo o papelão
= Temos dimensões = 1mx0,8m
Área = Comprimento × Largura
= 0,8m²
Nós convertemos para cm²
1 m² = 10.000 cm²
0,8m² = x cm²
Multiplicação cruzada
0,8m² × 10.000 cm² / 1 m²
= 8000 cm²
Passo 2
Sabendo que recortou 2 triângulos, ambos com 20cm de base e 30cm de altura
Encontramos a área de um triângulo
= 1/2 × base × altura
= 1/2 × 20 × 30
= 300cm²
Ele cortou 2 triângulos Portanto, o são dos dois triângulos = 300cm² × 2
= 600cm²
etapa 3
Ele também cortou 2 trapézios ambos com bases de 10cm e 20cm e altura de 7cm.
A área de um trapézio =
1/2 (a + b) h
= 1/2 (10cm + 20cm) × 7cm
= 1/2 × 30 × 7
= 105 cm²
Ele cortou dois trapézios, portanto
A área dos dois trapézios do corte = 105cm² × 2
= 210 cm²
Passo 4
A área total do papelão que foi cortado = 600cm² + 210cm²
= 810 cm²
Etapa 5
Determine em cm² quanto de papelão sobrou.
Isso é calculado como:
Área total do papelão - Área total que foi cortada
= 8000 cm² - 810 cm²
= 7190 cm²

Gemma makes a conjecture that the sum of an odd integer and itself is always an even integer. Which choice is the best proof of her conjecture?
A) Look at these different examples: 7 + 7 = 14, 13 + 13 = 26, 23 + 23 = 46. So the sum of an odd number and itself must be even
B) Let 2n + 1 be an odd number; (2n + 1) + (2n + 1) = 4n + 2. Because 4(n + 2) is divisible by 2, the sum of 2n + 1 and itself is even.
C) Let n represent an odd number, and let n + n be an even number. Therefore, n + n = n + n, which shows that the sum of an odd number and itself is even.
D) Every time you add an odd number and itself, the sum is an even number.Every time you add an odd number and itself, the sum is an even number.

On a map of Texas, one inch represents 75 miles. The distance between
San Antonio and Houston is 2.7 inches on the map. What is the distance
from San Antonio to Houston according to the map?
A 175 miles
B. 202.5 miles
C. 225.5 miles
D. 270 miles
Answer: B. 202.5 miles
Step-by-step explanation:
Multiply the scale ratio by the number of inches given on the map.
2.7 × 1 inch and 2.7 × 75 miles 2.7×75=202.5
2.7 inches represents 202.5 miles
