Answer: A
Step-by-step explanation:
The equation [tex]y=\frac{2}{3}x-1[/tex] is in slope-intercept form([tex]y=mx+b[/tex]). For a line to be parallel to another, it must have the same slope. The slope of the line given is 2/3. Thus, simply plug in 2/3 for the slope to get: [tex]y=\frac{2}{3} x+b[/tex]. Then, because the line passes through -6, 6, plug those values in for x and y, respectively. [tex]6=\frac{2}{3} *-6+b[/tex]
[tex]6=-4+b[/tex]
[tex]10=b[/tex]
Thus, the equation of the line is [tex]y = \frac{2}{3} x+10[/tex], or A

Al, Bert, and Rob determined that the sum of their ages is 62. Bert is twice as old as Rob, who is 10 years older than Al. How old is each?
Answer: AI is 8, Rob is 18, and Bert is 36
Step-by-step explanation:
Ok, so the sum of their age is 62. Bert is x2 of Rob. Also someone is 10 years older than AI, lets assume Rob is the guy that is 10 years older. x+y+10+(z times 2)=62. So lets solve it. 62-10=52. 52=x+y+(z times 2). Now if you think about it x and y is the same, because the 10 is already minused. So it's now x*2+z*2=52, if you assume it now, z is x+10. So now it is 52=x*2+(x+10)x2. Now we break out the brackets so its x*2+x*2+20=52. Lets simplify it. x*4+20=52, lets swift the 20 the the other side. x*4=52-20, x*4=32. 32/4=8 so 8 is x. Now we know AI is 8, Rob is 18, and Bert is 36!
If you could help I would really appreciate it, but if not that’s fine. Thank you.

b) 44.6%
c) 69.1
d) 125.0%
Answer:
c = 69.1
Step-by-step explanation:
because if you already have 280 rooms and it will increase to 405 rooms essentially all you have to do is 280/405 and that gives you about 69.1%

While back-to-school shopping, you find two pairs of jeans that cost $29 each, three shirts that cost $16 each, and a pair of shoes for $21. What is the total cost of these items, if the store is offering a 30% discount?
Answer:
$88.9
Step-by-step explanation:
First, you have to calculate the total cost of the items by adding up the results of multiplying the price of each item for its quantity:
Total cost=(29*2)+(16*3)+21
Total cost=58+48+21
Total cost=127
Now, you have to calculate 30% of that total and subtract that amount from the total cost:
127*30%=$38.1
127-38.1=$88.9
According to this, the answer is that the total cost of these items is $88.9 if the store is offering a 30% discount.

Haley sells apples from her apple orchard. Last week, she sold 516 apples. Of those apples, 107 or green apples and the rest were red apples. On Monday, Harry's sells 100 apples. Based on last week sales, white how many of the 100 apples she sells on Monday could be expecting to be green.
Answer: About 21 apples
Step-by-step explanation:
Number of apples sold last week = 516
Number of green apples = 107
Number of red apples = 516 - 107 = 409
Number of apples sold on Monday = 100
Number of apples expected to be green will be:
= 107/516 × 100
= 20.7
= 21 Approximately
Una fábrica de bolígrafos fabrica sus propios productos en tres colores distintos. 25 de su fabricación son bolígrafos azules, 13 son bolígrafos negros y el resto son bolígrafos rojos. a.- ¿Qué fracción de bolígrafos son bolígrafos rojos? b.- Si en total en un día se han fabricado 2250 bolígrafos ¿ Cuántos se han fabricado de cada color?
Answer:
a) 4/15
b) 900 bolígrafos azules
750 bolígrafos negros
600 bolígrafos rojos
Step-by-step explanation:
Una fábrica de bolígrafos fabrica sus propios productos en tres colores diferentes. 2/5 de su fabricación son bolígrafos azules, 1/3 son bolígrafos negros y el resto son bolígrafos rojos.
a) ¿Qué fracción de bolígrafos son bolígrafos rojos?
Deje que el número total de bolígrafos se represente como 1
La fracción de bolígrafos rojos =
1 - (Fracción de bolígrafos azules + Fracción de bolígrafos negros)
= 1 - (2/5 + 1/3)
El mínimo común denominador es 15
= 1 - (6 + 5/15)
= 1 - 15/11
= 4/15
Por lo tanto, la fracción de bolígrafos rojos = 4/15
b) Si se han fabricado un total de 2250 bolígrafos en un día, ¿cuántos se han fabricado de cada color?
Para bolígrafos azules
2/5 de su fabricación son bolígrafos azules,
= 2/5 × 2250 bolígrafos
= 900 bolígrafos azules
Para bolígrafos negros
1/3 son bolígrafos negros
= 1/3 × 2250 bolígrafos
= 750 bolígrafos negros
Para bolígrafos rojos
4/15 son bolígrafos rojos
= 4/15 × 2250 bolígrafos
= 600 bolígrafos rojos

-10(-1/2y+(-7/2)+7y=-25
Answer:
y = -5
Step-by-step explanation:
-10(-1/2y + (-7/2)) + 7y = -25
Let's first of all expand the bracket to get;
5y + 35 + 7y = -25
12y + 35 = -25
12y = -25 - 35
12y = -60
y = -60/12
y = -5

Hi there!
This looks like a diagnostic. I had to take one last week and it was horrible!
Anyway, the numerator is the product of 5 and the sum of x and y, which can be written as 5(x+y)
The denominator is the product of negative 8 and x, which can be written as -8x.

Cathy is making bows from a ribbon that is 11 1/5 yards long. She needs to cut the ribbon into equal pieces that measure 2/5 yard to make each bow. How many bows can Cathy make? Sam solved the problem below but got it incorrect. Explain Sam's error.
Answer:
28 bows
Step-by-step explanation:
Each bow is an equal piece.
1 bow = 2/5 yard
Total yard of ribbon = 11 1/5 yards
Hence:
2/5 yard = 1 bow
11 1/5 yards = x
2/5x = 11 1/5
x = 11 1/5 ÷ 2/5
x = 56/5 ÷ 2/5
x = 56/5 × 5/2
x = 28 bows
Therefore, Cathy can make 28 bows

The value of p and q in the right triangle are as follows:
p ≈ 30.6 units
q ≈ 14.9 units
How to find the side of a right triangle?A right triangle is a triangle that has one of its angles as 90 degrees. The sum of angles in a triangle is 180 degrees.
Therefore, the side of a right triangle can be found using trigonometric ratios as follows:
Let's find p and q using the trigonometric ratios.
Hence,
sin 64 = opposite / hypotenuse
opposite side = p
hypotenuse = 34
Therefore,
sin 64 = p / 34
cross multiply
p = 34 sin 64
p = 30.5589975742
p ≈ 30.6 units
Hence,
cos 64 = adjacent / hypotenuse
cos 64 = q / 34
cross multiply
q = 34 cos 64
q = 14.9046189908
q = 14.9 units
Therefore,
p ≈ 30.6 units
q ≈ 14.9 units

9 mugs for $45
What is the rate?
And what is the unit rate?
Answer: The unit rate is $5 per mug.
Step-by-step explanation:
To find the the unit rate, you will find the amount one mug will cost.
If there are 9 mugs then to get it to one, you will have to divide 9 by 9, and the same way you will have to divide 45 by 9.
45 / 9 = 5

Step-by-step explanation:
f(n) = 3(2)^n = 3 * 2^n.
We can see here that 3 is a constant term.
When n = 0, f(0) = 3 * 2^0 = 3.
Hence, on the 1st day 3 leaves fell. (A)
When n = 1, f(1) = 3 * 2^1 = 6.
When n = 2, f(2) = 3 * 2^2 = 12.
Notice that the number of leaves that fell keep doubling.
Therefore the number of leaves that fell on a given day is 2 times the number of leaves that fell on the previous day. (D)

Answer:
C) y = 2x + 3
Step-by-step explanation:
In slope intercept form(y = mx + b), b is the y intercept and m is the slope. The y intercept is y variable when the x variable is 0. In the chart, the y-intercept(b) is 3. Slope is identified by the different in y by the difference in x. In this chart the slope is 2. Now plug in the number into slope intercept form( y = 2x + 3).
