Answer:
y = 3x + 1
Step-by-step explanation:
the slope of the line of the given equation can bé find in this way: -a/b, where a is the number that multiplies x and b is the number that multiplies y
m = -3/-1 = 3
two parallel lines have the same slope, so also the line that we are a searching has m=3
now we can use this formula
y-y1 = m(x-x1) where y1 and x1 indicate the coordinates of the given point
y-(-2) = 3 (x-(-1)
y+2 = 3x + 3
y = 3x + 3-2
y = 3x + 1
At the craft store, Janice bought a bag of green and yellow marbles. She received 14 green marbles and 11 yellow marbles. What percentage of the marbles were green?
Answer: 56%
Step-by-step explanation:
Since Janice bought a bag of green and yellow marbles and she received 14 green marbles and 11 yellow marbles, the total number of marbles will be:
= 14 + 11 = 25 marbles
Number of Yellow marbles = 11
Number of Green marbles = 14
Total number of marbles = 25
The percentage of the marbles that were green will be:
= Number of Green marbles / Total marbles × 100
= 14/25 × 100
= 14 × 4
= 56%
Which equation below can be used to determine the missing angle in the triangle?
Select one:
x+75+60=180
75x+60x=180
75+60=x
x+75+60=90
Answer:You can use this fact to solve for the missing angle of a triangle. ... Remember -- the sum of the degree measures of angles in any triangle equals 180 degrees. Below is a picture of triangle ABC, where angle A = 60 degrees, angle B = 50 degrees and angle C = 70 degrees. ... Let x = the degree measure of each angle.

Answer:
24
Step-by-step explanation:
360 degrees, so 2+6+5+2=15
360/15=24
n=24
In which 3 statements below will the number 24 correctly fill in the blank? A) 2 feet = ___ inches B) 24,000 grams = ___ kg C) 3 gallons = ___ pints D) ___ pints = 12 cups E) 240 mg = ___ grams
Answer:
A,B and C.
Step-by-step explanation:
(A) 1 feet = 12 inches
So, 2 feet = 2 × 12 inches = 24 inches
(B) 1,000 grams = 1kg
So, 24,000 grams = (24,000÷ 1,000) = 24kg
(C) 1 gallon = 8 pints
So, 3 gallons = 3 × 8 pints = 24 pints
(D) 1 pints = 2 cups
So, 12 cups = (12÷ 2) = 6 pints
(E) 1 gram = 1000 mg
So, 240 mg = (240 ÷ 1,000) = 0.24 gram
Hence, A,B and C correctly fill with 24.

Answer:
7 days
Step-by-step explanation:
(a) Filling in the given information will result in two equations in the two unknowns. Dividing one by the other will tell you the value of b.
n=2
1.8 = A₀·b²
n=3
2.4 = A₀·b³
Dividing the second equation by the first gives ...
2.4/1.8 = (A₀·b³)/(A₀·b²) = b
4/3 = b
__
(b) Substituting this into the first equation, we can find A₀.
1.8 = A₀·(4/3)²
1.8(9/16) = A₀ = 1.0125
A₀ is the value of A when n=0. It is the area of the patch at the beginning of observation, before any days passed.
__
(c) The area will be 7 cm when ...
1.0125·(4/3)^n = 7
(4/3)^n = 7/1.0125 . . . . . . . . . . . . divide by A₀
n·log(4/3) = log(7/1.0125) . . . . . . take logarithms
n = log(7/1.0125)/log(4/3) ≈ 6.72092
It will take about 7 days for the area of the patch to exceed 7 cm.

Brenda took a math quiz last week. She got 21 problems correct and 4 problems incorrect. What percentage did Brenda get correct?
Answer:
84%
Step-by-step explanation:
Add the total number of questions (21+4 = 25)
divide 25 by 21
25/21 = 0.84
Multiply 0.84 by 100 to change it to a fraction
0.84*100 = 84%
The percentage that Brenda got correct was 84 percent

The 5th graders want to raise money for their overnight camping trip by selling cornbread during the school Chili Cook-Off contest. All the pans of cornbread are square. A pan of cornbread costs $12. The customers can buy any fractional part of a pan of cornbread and pay that fraction of $12. For example, ½ of a full pan costs ½ of $12.
Answer:
1 / 12 ; $1
Step-by-step explanation:
Pan was 1/4 full and she buys 1/3 of the cornbread in the pan
The fraction of cornbread she buys is :
1/3 of 1/4
1/3 * 1/4 = 1/12
Hence, she bought 1/12 of cornbread
The amount she pays :
Cost of 1 pan = $12
Therefore, the cost of 1/12 of a pan will be :
1/12 * $12 = $1
Hence, she'll pay $1

in a test, a hybrid car drove 4952 yards on 1 cup of gasoline. What is this rate in miles per gallon ?
Answer:45
Step-by-step explanation: There’s 16 cups in a gallon and the car goes 4952 yards per cup. You have to multiply the equivalency of a gallon by the yards to get your total distance in yards. Then, you would have to divide your total in yards (79,232) by the yards in a mile (1760). Your ratio would be around 45 miles per gallon.
Lana bought a sports car for $75,700. If the value of her car decreases 4.3% annually.
When using the exponential DECAY formula, what would be the value of r?
Given:
The initial value of the car = $75,700
Decreasing rate = 4.3%
To find:
The value of r in the exponential DECAY formula.
Solution:
The exponential decay formula is:
[tex]y=a(1-r)^t[/tex]
Where, a is the initial value, r is the rate of decay on decimal and t is the time period.
The initial value of the car is $75,700 and its value decreases 4.3% annually. So,
[tex]a=75,700[/tex]
[tex]r=\dfrac{4.3}{100}[/tex]
[tex]r=0.043[/tex]
The required exponential decay formula is:
[tex]y=75,700(1-0.043)^t[/tex]
Therefore, the value of r in the exponential decay formula is 0.043.
