A grocer mixes two kinds of n ur s. One kind costs $5.00/kg and the other $5.80/kg. How many kilograms of each type are needed to make 40kg of a blend worth $5.50/kg?
Answers
15 kilograms of the first type should be mixed with 25 kilograms of the other kind
How to determine the kilograms of each type needed to make 40kg?If the blend costs $5.50/kg, then:
on each kg at $5.00/kg, gain = $0.50 ($5.50 - $5.00)
on each kg at $5.80/kg, loss = $0.30 ($5.50 - $5.80)
Hence 3kg of the first kind must be mixed with 5kg of the second so that the gain on the first (3 x $0.50) is exactly the same as the loss on the second (5 x $0.30)
The required proportion is 3:5
In order to find how many kilograms of each type are needed to make 40kg, we will use the proportion obtained:
We have 3:5, total share = 3+5 = 8
First kind share = 3/8 x 40 kg = 15 kg
Second kind share = 5/8 x 40 kg = 25kg
Therefore, 15 kilograms of the first type is needed and 25 kilograms of the other kind is needed

Find the equation (in slope-intercept form) of the line with the given slope that passes through the point with the given coordinates.
slope: −43, ordered pair: (0,−25)
Answers
Answer:
[tex] \huge{ \bold{y = - 43x - 25}}[/tex]
Step-by-step explanation:
Equation of a line in slope-intercept form is given by
[tex]y = mx + c[/tex]
where
m is the slope
c is the y intercept
From the question
m = - 43
In order to find c we substitute the point (0,−25) into the equation y = mx + c
That's
[tex] - 25 = - 43(0) + c \\ - 25 = 0 + c \\ c = - 25[/tex]
We now substitute m and c into the equation
We have the final answer as
[tex] \bold{y = - 43x - 25}[/tex]

x^2+32+116=12x
Answers
Answer:
Below
Step-by-step explanation:
x^2 + 32 + 116 = 12x 1st intermediate step: put everything on one side
x^2 -12x + 148 = 0 2nd intermediate step : re-arrange with constant on R
x^2 -12x = -148 3 rd intermediate step : take 1/2 of the 'x' coefficient
square it and add to both sides
x^2 -12x + 36 = -148 + 36 4th intermediate step : simplify

Which pair of lines are perpendicular?
A. y = -8 and y = 2
B. x = 4 and y = -1
C. x-y = 7 and y = x + 3
D. y = -4x + 1 and 8x + 2y = -10
Answers
Applying the slope-intercept form for perpendicular lines, we find out that no given pair of lines are perpendicular.
There are 4 different pairs of lines given to us.
We have to find out the pair of lines that are perpendicular to each other.
We know that the general equation of a line in slope-intercept form is represented as -
y = mx + c --- (1)
where
(x, y) = coordinates of the lines
m = slope of the line
c = y-intercept
It is also known to us that for two lines to be perpendicular the product of their slope must be equal to -1.
A. y = -8 and y = 2
Comparing these two lines to the general equation of a line in equation (1), we see that the slope of both these lines is equal to 0.
So, these two pair of lines are not perpendicular.
B. x = 4 and y = -1
Comparing these two lines to the general equation of a line in equation (1), we see that the slope of both these lines is equal to 0.
So, these two pair of lines are not perpendicular.
C. x - y = 7 and y = x + 3
Now, x - y = 7
=> -y = 7 - x
=> y = x - 7
Comparing this to the equation (1), we have slope of the line, m = 1.
Also, y = x + 3
Comparing this to the equation (1), we have slope of the line, m = 1.
We see that the product of the slope of these pair of lines is not equal to -1.
So, these two pair of lines are not perpendicular.
D. y = -4x + 1 and 8x + 2y = -10
Now, y = -4x +1
Comparing this to the equation (1), we have slope of the line, m = -4.
Also, 8x + 2y = -10
=> 2y = -8x - 10
=> y = -4x - 10
Comparing this to the equation (1), we have slope of the line, m = -4.
We see that the product of the slope of these pair of lines is not equal to -1.
So, these two pair of lines are not perpendicular.
Thus, according to the slope-intercept form for perpendicular lines, we find out that no given pair of lines are perpendicular.

How many cubic inches are in an aluminum can with a 2 3/5 diameter and 5 1/4 in height?
Answers
According to the volume of cylinder formula, an aluminum can with a 2 3/5 diameter and 5 1/4 in height are in 27.86 cubic inches.
Volume of Cylinder
The formula to calculate the volume of the cylinder is
Volume of a cylinder = πr²h cubic units.
where
r refers the radius
h refers the height.
Given,
Here we have an aluminum can with a 2 3/5 diameter and 5 1/4 in height and now we have to find the volume in cubic inches.
While we looking into the given question, we know the following values,
Diameter = 2 3/5
When we simplify it, then we get the value of diameter as
d = 13/5 or 2.6
Similarly, the value of height is rewritten as,
h = 5.25
So, based on the formula of volume of cylinder,
We get the value as,
=> V = π x (2.6/2)² x 5.25
Apply the value of π as 3.14, then we get,
=> V = 3.14 x (1.3)² x 5.25
=> V = 16.485 x 1.69
Therefore, the volume in cubic inches is 27.86 cubic inches.

This image shows two triangles which have 2 congruent sides and one congruent angle.
Is it ASA?
There is only one congruent angle, so this cannot be congruent by ASA
Is it AAS?
By the same reasoning, it cannot be congruent by AAS.
Is it HL?
Although there are 2 congruent sides, neither one is the hypotenuse. Is is not congruent by HL.
There is no such thing as SSA congruence, because it is actually possible to have 2 non-congruent triangles who have 2 congruent sides and 1 congruent angle. Therefore, these are NOT CONGRUENT

Answers
The simple interest owned for the use of the money is $2625.
What is Simple Interest?
Simple interest is a quick and simple way to figure out how much money has accrued interest. Interest is always applied to the original principal amount and is calculated at the same rate for each period of time. Any bank where we deposit money will pay us interest on that amount. Simple interest is one of many forms of interest that banks charge. Now, let's first clarify what a loan is before delving further into the idea of simple interest. A loan is a sum of money that someone borrows from a bank or other financial institution to cover expenses. Home loans, auto loans, student loans, and personal loans are a few instances of loans.
In the given question we have:
Principal amount = 7000$,
Rate of interest r = 7.5%,
Time t = 15 months;
So, applying the formula to calculate simple Interest:
S.I = [tex]\frac{PRT}{100}[/tex]
S.I = [tex]\frac{7000 \times 7.5 \times 15}{ 12 \times 100}[/tex]
