Laura has 160 pounds of green beans at her vegetable stand. If she sells 10 pounds of green beans every hour, what is the percent decrease in green beans after 3 hours?
Answer:We have,
Beans sold in 1 hour = 10 pounds
So, Beans sold in 3 hours = 30 pounds
Decrease in green beans after 3 hours is 30 pounds.
Now,
Step-by-step explanation:
Answer:
18,75%
Step-by-step explanation:
3 x 10 = 30
so, she sold 30 pounds in 3 hours
160/100=1.6
1% - 1.6 pounds
30/1.6=18,75
Lucy and JoJo need to make 140 cupcakes for the school dance. Lucy made 35 of the cupcakes JoJo made 42 cupcakes What fraction of the cupcakes do Lucy and JoJo still need to make? (Use / as a fraction bar.)
Answer:
16/35
Step-by-step explanation:
From the question we are given:
total number of cupcakes needed for the school dance = 140 cupcakes
Lucy made 35cupckes
JoJo made 42 cupcakes
Total cupcakes made by JoJo and Lucy = 35+42 = 76cupcakes
Remaining cupcakes still needed to be made = 140 - 76 = 64cupckes
Fraction of the cupcakes that Lucy and JoJo still need to make = 64/140
Fraction of the cupcakes that Lucy and JoJo still need to make = 16/35
Hence the fraction of the cupcakes that Lucy and JoJo still need to make is 16/35

f(X)= 3x^2- 30x+5
Step-by-step explanation:
f(X)= 3(x-5)^2-70
= 3(x^2-2.x.5+ 5^2) -70
= 3(x^2-10x+25)-70
= 3x^2-30x+75-70

evaluate 7p+6(p/q)2 q if p = 6 and q = 3. show your work and give an explanation for each step .
Answer:
63 is the required value.
Step-by-step explanation:
We need to find the value if p = 6 and q = 3 in the below expression i.e.
[tex]7p+6(\dfrac{p}{q})^2-q[/tex]
Put p = 6 and q = 3 in the above expression.
[tex]=7(6)+6(\dfrac{6}{3})^2-3\\\\=42+6(2)^2-3\\\\=42+24-3\\\\=63[/tex]
So, the value of the given expression is 63.

Answer:
X and y both equal 94 degrees
Step-by-step explanation:
Suplimentary angles equal 180 degrees so therefore a straight line equals 180 degree and 86 of those degrees are taken up so 180-86=94 and x and y are both the same angles so therefore x and y both equal 94 degrees

Use the interactive number line to help complete each exercise. Place points at -1 and -4. Complete the inequality: -1 -4. Place points at the opposites for each number. Which inequality statement is true?
Question might not be complete
Answer and explanation:
The signs -1 and -4 lie on the negative side of the number line, left of zero(positive right of zero).
The opposites for each number would be +1 and +4 which would all be on the right side of zero on the number line
Inequality signs or statements to represent greater and lesser number on the number line using the numbers above as examples would be:
-1<+1
-4<-1
+1>-1
+1<4
-1-4<1+4
Numbers that don't have signs attached to them are automatically positive numbers

Answer:
That is correct AS A DECIMAL but since it is asking for the exact form the correct answer would be 3 √ 5
Step-by-step explanation:
Two linear equations are represented by using the tables below.
A 2-column table with 4 rows is titled Equation A. Column 1 is labeled x with entries negative 5, negative 2, 0, 1. Column 2 is labeled y with entries negative 4, negative 1, 1, 2.
A 2-column table with 4 rows is titled Equation B. Column 1 is labeled x with entries negative 6, negative 3, 3, 6. Column 2 is labeled y with entries negative 4, negative 2, 2, 4.
The data points for equation A are plotted on the coordinate plane below and are connected by using a straight line.
On a coordinate plane, a line goes through points (negative 5, negative 4), (negative 2, negative 1), (0, 1), (1, 2).
What is the solution to the system of equations?
(–6, –4)
(–5, –4)
(–3, –2)
(0, 1)
Answer:
(–3, –2)
Step-by-step explanation:
A linear equation is an equation in the form y = mx + b, where m is the slope of the line and b is the y intercept.
Equation A is represented by the points:
x: -5 -2 0 1
y: -4 -1 1 2
Equation A can be gotten by picking any two pair of points. Let us use (-5, -4) and (0, 1). We use this formula:
[tex]y- y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-(-4)=\frac{1-(-4)}{0-(-5)} (x-(-5))\\\\y +4=x+5\\\\y=x+1[/tex]
Equation B is represented by the points:
x: -6 -3 3 6
y: -4 -2 2 4
Equation B can be gotten by picking any two pair of points. Let us use (-6, -4) and (3, 2). We use this formula:
[tex]y- y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-(-4)=\frac{2-(-4)}{3-(-5)} (x-(-6))\\\\y +4=\frac{2}{3}( x+6)\\\\y+4=\frac{2}{3} x+4\\\\y=\frac{2}{3}x[/tex]
The solution to the system of equations is gotten by solving y = x + 1 and y = (2/3)x simultaneously.
Substitute y = (2/3)x in y = x + 1:
(2/3)x = x + 1
2x = 3x + 3
x = -3
Put x = -3 in y = (2/3)x
y = (2/3) (-3) = -2
Hence (-3, -2) is the solution

Answer:
[tex]\frac{2}{k+2}[/tex]
Step-by-step explanation:
Given the expression:
[tex]\frac{4k+2}{k^2-4} * \frac{k-2}{2k+1}[/tex]
We are to find the product as shown:
[tex]= \frac{4k+2}{k^2-4} * \frac{k-2}{2k+1}\\\\= \frac{2(2k+1)}{k^2-2^2} * \frac{k-2}{2k+1}\\\\= \frac{2(2k+1)}{(k-2)(k+2)} * \frac{k-2}{2k+1}\\\\= \frac{2}{k+2} * 1\\\\= \frac{2}{k+2}[/tex]
Hence the required function is [tex]\frac{2}{k+2}[/tex]

A rectangle has a height of m + 8 and a width of 2m3 + m2 + 3m.
Answer:
A=2m⁴+17m³+11m²+24m
Step-by-step explanation:
The area of rectangle is length × width
A=LW
A=(m+8)(2m³+m²+3m)
A= 2m⁴+m³+3m²+16m³+8m²+24m
A=2m⁴+m³+16m³+3m²+8m²+24m
A=2m⁴+17m³+11m²+24m

The center of a circle is at (2, −5) and its radius is 12.
What is the equation of the circle?
(x−2)2+(y+5)2=144
(x+2)2+(y−5)2=24
(x−2)2+(y+5)2=24
(x+2)2+(y−5)2=144
Answer:
The equation of the circle is (x - 2)² + (y + 5)² = 144 ⇒ A
Step-by-step explanation:
The form of the equation of the circle is (x - h)² + (y - k)² = r², where
r is the radius of the circleh, k are the coordinates of the center of the circleLet us solve the question
∵ The center of the circle is at (2, -5)
→ From the rule above
∴ h = 2 and k = -5
∵ The radius of the circle is 12
∴ r = 12
→ Substitute the values of r, h, and k in the form of the equation above
∵ (x - 2)² + (y - -5)² = (12)²
∴ (x - 2)² + (y + 5)² = 144
∴ The equation of the circle is (x - 2)² + (y + 5)² = 144

7. Renting bowling shoes costs $5. Bowling costs $4
per game. Which equation can be used to find y, the
total cost of bowling, if x represents the number of
games played.
A. y = 5x + 4
B. y = 5 + 4x
C. y = 5x + 4x
D. y = 5x - 4
Answer:
B. y = 5 + 4x
Step-by-step explanation:
x represents the number of games played so its y = 5 + 4x because bowling costs $4 per game
3. What % of 100 is 13?
Answer:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 13 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 13 is 100%, so we can write it down as 13=100%.
4. We know, that x is 100% of the output value, so we can write it down as x=100%.
5. Now we have two simple equations:
1) 13=100%
2) x=100%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
13/x=100%/100%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 100% of 13
13/x=100/100
(13/x)*x=(100/100)*x - we multiply both sides of the equation by x
13=1*x - we divide both sides of the equation by (1) to get x
13/1=x
13=x
x=13
now we have:
100% of 13=13

Find the next three terms.
1,2,4,8,_,_,_,
Answer:
16, 32, 64
Step-by-step explanation:
There is a common ratio between consecutive terms, that is
2 ÷ 1 = 4 ÷ 2 = 8 ÷ 4 = 2
Thus to obtain any term in the sequence multiply the previous term by 2
a₅ = a₄ × 2 = 8 × 2 = 16
a₆ = a₅ × 2 = 16 × 2 = 32
a₇ = a₆ × 2 = 32 × 2 = 64
