Apples cost $2/lb but 15 apples cost $4. How many pounds does an apple weigh?
A 2/15
B 15/2
C 1/15
D 1/30
E 15
Answers
Well, you start out by recognizing that 4/5ths of an ounce equals 1/5 of the apples weight. Therefore, you must multiply 4/5 by 5 to get the whole of the Apple. (1/5*5).
So, this is the lines,
4/5*5= 20/5, or 4 ounce
Another way, is with decimals, so
0.8*5=4.0

Answers
Answer:
The answer to your problem is, A and C
4x² + 16x = 0
(x+4)(x−12)=0
Step-by-step explanation:
The first and the third equation can be solved by using the zero product property. Let us examine each equation.
4x²+16x=0
4x(x+4)=0
4x=0 and x+4=0
Where x1=0 and x2=-4
Answer 2:
(x+4)(x-12)=0
x1=-4 and x2=12
Thus the answer to your problem is, A and C
4x² + 16x = 0
(x+4)(x−12)=0
A car travels a distance of 112km at an average Speed of 70km/h. It then Travells Further for 60km at an average Speed of 50 km/hr. Calculate for the entire Journey of the total time taken.
Answers
The total time taken for the entire journey is 2.8 hours.
To calculate the total time taken for the entire journey, we can use the formula:
Time = Distance / Speed
For the first part of the journey, the car travels a distance of 112 km at an average speed of 70 km/h. Using the formula, the time taken for this part is:
Time1 = 112 km / 70 km/h = 1.6 hours
For the second part of the journey, the car travels a further distance of 60 km at an average speed of 50 km/h. Again, using the formula, the time taken for this part is:
Time2 = 60 km / 50 km/h = 1.2 hours
To find the total time for the entire journey, we sum up the times for both parts:
Total Time = Time1 + Time2 = 1.6 hours + 1.2 hours = 2.8 hours

plus commission on his sales. He receives 10% for the first $5000 in sales and 15%
anything over $5000.
Last week, he sold $17000 in computer equipment. Find his gross pay.
Round to the nearest whole dollar.
For your answer, do NOT include symbols, commas, words, etc.
HELP PLS
Answers
Chris' gross pay for the week after selling computer equipment worth $17,000 is $2,600.
How is the gross pay determined?The gross pay is the addition of the base pay and the sales commission.
The sales commission is graduated and computed as follows:
Chris' base pay = $300
Sales Commissions:
First $5,000 = 10%
Above $5,000 = 15%
Last week's sales = $17,000
10% Commission = $500 ($5,000 x 10%)
15% Commission = $1,800 ($17,000 - $5,000 x 15%)
Total Commission = $2,300
Gross pay = Base Pay + Commission
= $2,600 ($300 + $2,300)

If there is no solution, enter "no"; if there are infinitely many solutions, enter "inf."
Answers
The solution to the system of equations is (x, y) = (-261/47, 44/47) as an ordered pair.
To solve the given system of equations:
Equation 1: 8x + 9y = -36
Equation 2: x + 7y = 1
We can use the method of substitution or elimination to find the values of x and y. Let's use the method of substitution:
From Equation 2, we can solve for x:
x = 1 - 7y
Substituting this value of x into Equation 1:
8(1 - 7y) + 9y = -36
8 - 56y + 9y = -36
-47y = -44
y = 44/47
Substituting the value of y back into Equation 2 to find x:
x + 7(44/47) = 1
x + 308/47 = 1
x = 1 - 308/47
x = (47 - 308)/47
x = -261/47
Therefore, as an ordered pair, the solution to the system of equations is (x, y) = (-261/47, 44/47).

Answers
∠X = 89°, ∠Y = 90°, ∠Z = 40° ∠X+∠Z=180---------> ∠X=180-∠Z-----> ∠X=180-40°----> ∠X=140°
→ (2b+6)+(3b-1)=90----> 5b+5=90----> 5b=85----> b=17°
→ ∠Z=2b+6---- 2*17+6-----> ∠Z=40°
→ ∠Y=3b-1---> ∠Y=3*17-1---> ∠Y=50°
angle Y and W are supplementary angles
so
→ ∠Y+∠W=180---------> ∠W=180-∠Y------> ∠W=180-50----> ∠W=130°
angle X and Z are supplementary angles
so

Therefore, the answer is
∠Z=40°
write 4y-3x=2 in slope intercept form
Answers
Answer:
y = \(\frac{3}{4}\) x + \(\frac{1}{2}\)
Step-by-step explanation:
To change the equation to slope intercept form, you have to isolate the y on one side and put the slope and x on the other side.
4y - 3x = 2
*Add 3x to both sides
4y = 2 + 3x
*Divide both sides by 4
y = 2/4 + 3/4x
*Simplify the equation
y = 1/2 + 3/4x

Answers
False
The median car price is the one right in the middle of the price list. To find the median, we first need to rank the prices from lowest to highest.
The ordered price list looks like this:
$3,999; $4,500; $4,999; $5,000; The median price is $4,999, which is the median price. The average price is not $4,799.60.
Median is a measure of the central tendency of a dataset. The value that separates the top and bottom halves of the record. To find the median, we need to enter the values in the dataset in order from lowest to highest. If the dataset has an odd number of values, the median is the mean.
For example, given the following five values: For 3, 5, 7, 9, 11, the median is the median, so the median is 7. If the dataset has an even number of values, the median is the average of the two middle values. For example, given the following 6 values:
For 3, 5, 7, 9, 11, 13, the median is (7 + 9)/2 = 8. In this case, there are 5 values, which are odd, so the median is the median. , which is $4,999.

Answer:
78.5%
Step-by-step explanation:
the percent of time the point will land in the square can be determined by dividing the area of the square by the area of the circle
A(circle) = 3.14(1)²
A(circle) = 3.14

Find the equation of the straight line which passes through the point (-1,3) and make intercept on x - axis as thrice that on y - axis .
Answers
Answer:
\(y = -\frac{1}{3}x + \frac{8}{3}\)
Step-by-step explanation:
Given
\((x_1,y_1) = (-1,3)\)
\(Intercept\ on\ x-axis = Intercept\ on\ y-axis.\)
Required
Determine the equation
First, we calculate the intercepts using:
\(\frac{x}{a} + \frac{y}{b} = 1\)
Where
b = Intercept on y axis.
a = Intercept on x axis.
From the question:
\(a = 3b\)
The equation becomes:
\(\frac{x}{3b} + \frac{y}{b} = 1\)
Multiply through by 3b
\(x + 3y = 3b\)
We have: \((x_1,y_1) = (-1,3)\)
So:
\(-1 + 3 * 3 = 3b\)
\(8 = 3b\)
Make b the subject
\(b = \frac{8}{3}\)
Substitute \(b = \frac{8}{3}\) in \(x + 3y = 3b\) to get the equation
\(x + 3y = 3 * \frac{8}{3}\)
\(x + 3y = 8\)
Make 3y the subject
\(3y = -x + 8\)
Make y the subject
\(y = -\frac{1}{3}x + \frac{8}{3}\)
You sailed 0.055 units to the left and found treasure at 0.085 units find where the ship started
Answers
Starting position = Treasure location + distance sailed to the left
Since we know going in the left direction typically is a means of subtraction, we can use inverse operations to solve this. We can set up an addition problem to solve this:
Starting position = 0.085 + 0.055
Starting position = 0.03 units
Therefore, the ship started at 0.03 units.
Determine the equation of the parabola that opens to the right, has focus (13,-6),
and a focal diameter of 28.
Answers
The equation of the parabola is\((y + 6)^2 = 4(x - 13)\), where the vertex is (13, -6) and the distance between the directrix and focus is 14.
To determine the equation of the parabola, we need to use the standard form for a parabola with a horizontal axis:
\((x - h)^2 = 4p(y - k)\)
Where (h, k) represents the vertex of the parabola, and p is the distance from the vertex to the focus (and also from the vertex to the directrix).
Given that the parabola opens to the right, the vertex will be on the left side. Let's assume the vertex is (h, k).
We know that the focus of the parabola is at (13, -6), so the distance from the vertex to the focus is p = 13 - h.
We are also given that the focal diameter is 28, which means the distance between the directrix and the focus is twice the distance from the vertex to the focus.
Therefore, the distance from the vertex to the directrix is d = 28/2 = 14.
