Grapes cost $2.39 per pound and bananas cost $0.59 per pound. You have $15 to spend on g pounds of grapes and b pounds of bananas. Make an input-output table, graph the table, write the equation: y=mx+b, and give 5 possible combinations.
Answer:
2.39g + 0.59b = 15
Step-by-step explanation:
Algebraic Expressions
Let:
g = pounds of grapes
b = pounds of bananas
Since grapes cost $2.39 per pound, g pounds of grapes cost 2.39g dollars.
Since bananas cost $0.59 per pound, b pounds of bananas cost 0.59b dollars.
The total cost of fruits is:
C = 2.39g + 0.59b
And this cost is equal to $15:
2.39g + 0.59b = 15
This is the equation that relates the costs of the fruits. If another condition was given, then we could find how many pounds of each fruit is to be purchased.
if a fish swims 7/8 of a depth of a 32 ft deep lake how many feet down did the fish swim

As Venus revolves around the sun, it travels at a rate of approximately 22 miles per second. Convert this rate to kilometers per second. At this
rate, how many kilometers will Venus travel in 10 seconds? In your computations, assume that 1 mile is equal to 1.6 kilometers. Do not
round
your answers.
Answer:
13.75 m/sec
Step-by-step explanation:
Since the 'per second' part stays the same, simply multiply 22 kilometers by the reciprocal of 1.6:
[tex]22(\frac{1}{1.6})[/tex]
then simplify the fraction:
[tex]= 22(\frac{10}{16})[/tex]
[tex]= 22(\frac{5}{8})[/tex]
and solve to get
[tex]= 13 \frac{3}{4}[/tex] miles per second as the answer.

The figure shows a triangle with 2 congruent sides. The angle between the congruent sides measures x degrees and a different angle measures 70 degrees. The angles opposite the congruent sides of an isosceles triangle are congruent. Find the value of x in the triangle.
Answer:
40°Step-by-step explanation:
Since the triangle is isosceles and the angle between the congruent sides is x, the other two angles measure the same value.
Sum of the interior angles is 180°:
x + 2*70° = 180°x + 140° = 180°x = 40°Put the following equation of a line into slope-intercept form, simplifying all fractions. 15x - 3y = 15

A quadrant is the area that is divided into the x and y axes
The quadrants in which tan [tex]\theta[/tex] and cot [tex]\theta[/tex] are positive are I and III
How to determine the quadrantsThe tangent of an angle is calculated as:
[tex]\tan(\theta) = \frac{sin(\theta)}{\cos(\theta)}[/tex]
While the cotangent of the angle is calculated as:
[tex]\cot(\theta) = \frac{cos(\theta)}{\sin(\theta)}[/tex]
The above equations mean that:
For the tangent and cotangent of an angle to be positive, then the sine and the cosine of the angle must have the same sign.
In the first quadrant, the sine and the cosine angles are positive.In the third quadrant, the sine and the cosine angles are negative.Hence, the quadrants in which tan [tex]\theta[/tex] and cot [tex]\theta[/tex] are positive are I and III

A researcher is comparing the effectiveness of three devices designed to help people who snore. There are 120 people who snore participating in the experiment. Using a table of random digits, the researcher will randomly place the participants into three equally sized treatment groups suitable for comparison.
How many unique random numbers need to be selected from the table of random digits?
3
40
80
120
Answer:
40
Step-by-step explanation:
Divide 120 by 3
Meaning you are taking the total nuber by the nuber which is going to be divided
The total number of unique random numbers needed is 120 numbers.
What is Statistic?A statistic is a piece of data derived from a subset of a population. It's the inverse of a parameter — census data, which polls everyone.
To randomly assign 120 people into three equally sized treatment groups, the researcher needs to select 120 unique random numbers from the table of random digits.
Each number will correspond to one of the 120 participants and determine which treatment group they will be assigned to.
Since there are three equally sized groups, each group should have 40 participants. Therefore, the researcher needs to select 40 unique random numbers for each group.
So, the total number of unique random numbers needed is:
3 groups x 40 numbers per group = 120 numbers
Therefore, the correct answer would be option (D) 120.

The slope of the red line is -3/7.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
We have two lines one is red and other is green.
As, the slope of green line is -3/7 and the red line is parallel to green line.
We know that the parallel lines have same slope.
Then, the slope of red line is -3/7.

According to the Internal Revenue Service (IRS), a single taxpayer with a tacable income between $63,550 and $132.600 in 2000 paid $14,382 plus 31% of the amount over $63.550. If Azim paid $23,665 in federal
income tax for 2000, then what was his total taxable income for the year?
Answer:
$93,495
Step-by-step explanation:
The tax amount is described as ...
t(x) = 14,382 +0.31(x -63550)
This can be simplified a bit to ...
t(x) = 0.31x -5318.50
Using 23,665 for the amount paid, we find the income to be ...
23665 = 0.31x -5318.50
28983.50 = 0.31x . . . . . . . . add 5318.50
93495.16 = x . . . . . . . . . . . divide by 0.31
Azim's total taxable income for the year was about $93,495.

If you were to sketch a circle graph for the data shown in the table below, about what fraction of the circle would represent dogs?
Answer:
A
Step-by-step explanation:
To find the fraction of how many would choose dogs, we would have to add all of it together to find the sample size, then divide the number of people who would choose dogs to find the percentage of people who would represent dogs.
Using that percentage, we can then find the fraction close to it.
Let's find the sample size, 43+35+62=140
People who choose dogs: 35
Let's divide to find the fraction: [tex]\frac{35}{140} =\frac{1}{4}[/tex]
(we can simplify this fraction by seeing that four '35's fit into 140.

2. y = 55.(1 – 0.02)'
A. Does this function represent exponential
growth or exponential decay?
the tale-tell part of an exponential expression will be the "rate" or namely the part inside the parentheses, if the rate is less than 1, is Decay, if it's more than 1 is Growth.
(1 - 0.02) => 0.98, and 0.98 is less than 1, thus is Decay.
The given exponential function represent exponential decay.
The given function is [tex]y=55(1-0.02)^t[/tex].
The quantity decreases slowly after which the rate of change and the rate of growth decreases over a period of time rapidly. This decrease in growth is calculated by using the exponential decay formula.
