After addressing the issue at hand, we can state that Javier's model equation predicts that there are 30 fifths in 6 wholes.
What is equation?A mathematical statement known as an equation demonstrates the equivalence of two expressions when they are joined by the equals sign ('='). As an illustration, 2x - 5 = 13. 2x-5 and 13 are examples of expressions. The letter '=' joins the two expressions together. An equation is a mathematical formula with two algebraic expressions on either side of the equal sign (=). It shows how the left and right formulas have an equivalent relationship. In any formula, L.H.S. = R.H.S. (left side = right side).
To describe Javier's work, one division equation with a fraction might be written as follows:

144 is 90% what is the other 10 percent
Answer:
the missing 10% of 144 is 16. The whole amount would be 144 + 16 = 160.
Step-by-step explanation:
To find the missing 10%, you can use the fact that 100% is equal to the whole amount, and set up a proportion:
90/100 = 144/x
Simplifying this proportion, you can cross-multiply:
90x = 100 * 144
Then, you can solve for x:
x = (100 * 144) / 90
x = 160
Therefore, the missing 10% of 144 is 16. The whole amount would be 144 + 16 = 160.
You deposit $6000 in an account earning 6% interest compounded quarterly. How much will you have in the account in 15 years? Round your answer to the nearest cent.
Step-by-step explanation:
The formula to calculate the future value of a present value deposit with compounding interest is:
FV = PV × (1 + r/n)^(n*t)
Where:
PV = Present Value (the initial deposit)
r = Annual interest rate (as a decimal)
n = Number of compounding periods per year
t = Number of years
Using this formula, we can calculate the future value of the $6000 deposit after 15 years:
PV = $6000
r = 6% = 0.06
n = 4 (compounded quarterly, i.e. 4 times per year)
t = 15 years
FV = $6000 × (1 + 0.06/4)^(4*15)
FV = $6000 × 1.458^60
FV = $6000 × 6.2565
FV = $37,539.00
Therefore, the future value of the $6000 deposit after 15 years with quarterly compounding at 6% interest rate is $37,539.00.

What is surface area
Given that three factors are given and the surface area is required, this means that we are dealing with a three-dimensional shape. Where the above is a rectangular prism, the surface area = 118 In².
What is the explanation for the above response?
Surface area is the measure of the total area that the surface of a three-dimensional object occupies.
To calculate the surface area of an object, you need to add up the areas of all its faces. The formula for finding the surface area of a rectangular prism, which has three pairs of congruent rectangular faces, is:
Surface area = 2(lw + lh + wh)
where l, w, and h are the length, width, and height of the rectangular prism, respectively.
So, if we have a rectangular prism with the following dimensions:
Length (l) = 3.5 inches
Width (w) = 4 inches
Height (h) = 6 inches
The surface area can be calculated as follows:
Surface area = 2(lw + lh + wh)
= 2(3.5 x 4 + 3.5 x 6 + 4 x 6)
= 2(14 + 21 + 24)
= 2(59)
= 118In²
Therefore, the surface area of this rectangular prism is 118 In².

y=2/5+2 how to get the x intercept
Answer:
Step-by-step explanation:
The equation you provided, y = 2/5 + 2, appears to be missing the variable x. Assuming you meant y = 2/5x + 2, here's how you can find the x-intercept:
To find the x-intercept, we need to find the value of x when y = 0. This is because the x-intercept is the point on the graph where the line crosses the x-axis, and at that point, the y-coordinate is always 0.
So, we can set y = 0 in the equation:
0 = 2/5x + 2
Subtracting 2 from both sides:
-2 = 2/5x
Multiplying both sides by 5/2:
-5/2 = x
Therefore, the x-intercept is at the point (-5/2, 0).
what is the anwser to finding the radius
The radius of the circle is r = 3.75
What is the radius of a circle?The radius of a circle is the distance from its center to its circumference.
To find the radius of the circle, we see that there is a right-angle triangle there. So, using Pythagoras' theorem, we have that
AC² = AB² + BC²
(6 + r)² = 9² + r²
Expanding the brackets, we have that
36 + 12r + r² = 81 + r²
Cancelling out r², we have that
36 + 12r = 81
Subtracting 36 from both sides, we have that
12r = 81 - 36
12r = 45
r = 45/12
r = 15/4
r = 3.75
So, the radius is r = 3.75

Ingrum Corporation produces and sells two products. In the most recent month, Product R38T had sales of $33,000 and variable expenses of $8,840. Product X08S had sales of $54,000 and variable expenses of $32,050. The fixed expenses of the entire company were $36,130. The break-even point for the entire company is closest to:
Answer:
Therefore, the break-even point for the entire company is approximately 0.784 or 78.4%.
Step-by-step explanation:
To calculate the break-even point, we need to find the total contribution margin, which is the difference between the total sales revenue and total variable expenses.
For Product R38T, the contribution margin is $33,000 - $8,840 = $24,160.
For Product X08S, the contribution margin is $54,000 - $32,050 = $21,950.
The total contribution margin for both products is $24,160 + $21,950 = $46,110.
To calculate the break-even point, we divide the total fixed expenses by the total contribution margin:
Break-even point = Total fixed expenses / Total contribution margin
= $36,130 / $46,110
= 0.784
Therefore, the break-even point for the entire company is approximately 0.784 or 78.4%.

about blood types and Rhesus factor to solve this situation.
Two friends, Mike and Jake were returning late at night from a club in the same car. Suddenly, Mike, who was driving, lost control of
the car and they crashed into a big tree. Mike ended up with only a few bruises and scratches, but Jake got hurt.
Jake had internal bleeding and was taken to a hospital, but he lost a lot of blood and needed a blood transfusion. Mike, feeling
responsible for his friend's condition, wanted to donate blood to his friend. Both Mike and Jake had blood type O. So, in the ER, Mike
gave 2 pints of blood to Jake.
Two weeks later, Jake became anemic. So, Mike, being a good friend, decided to give blood again. However, after the second
transfusion, Jake went into an anaphylactic shock (severe immune response) and almost died.
What, do you think, was the problem here? Your answer should have two parts:
1. Explain, what happened in Jake's body after the first blood transfusion - why did he become anemic so soon after the transfusion?
(hint: it's not from bleeding)
2. Explain, what happened after the second blood transfusion - why did Jake go into an anaphylactic shock?
1.Jake became anemic after the first blood transfusion because his body reacted to the foreign antigens.
2.He went into an anaphylactic shock after the second transfusion due to an even stronger allergic reaction.
1. After the first blood transfusion, Jake became anemic because he was given type O blood, which is not compatible with his own blood type. Incompatible blood transfusions occur when a person is given blood that carries a different antigen than the one they have. In this case, Jake was given type O blood, which carries both the A and B antigens, while Jake’s own blood carries the Rh antigen. Therefore, Jake’s body reacted to the foreign antigens and created antibodies to fight against them. This reaction caused Jake to become equation anemic, as his body was not able to absorb the oxygen from the transfused blood.
2. After the second blood transfusion, Jake went into an anaphylactic shock because he was given type O blood, which carries both the A and B antigens, while Jake’s own blood carries the Rh antigen. Since Jake’s body had already created antibodies to fight against the foreign antigens, when it was exposed to the same foreign antigens a second time, his body reacted with an even stronger immune response. This reaction caused Jake to go into an anaphylactic shock. In other words, the second transfusion caused an allergic reaction in Jake’s body, which was much more severe than the allergic reaction caused by the first transfusion.

You may choose more than one correct answer. m 4 + m 5 + m 6 = 180. 1 and 4 are alternate interior angles. m 5 = m 3 + m 2. m 5 + m 1 = 180.
m4 + m5 + m6 = 2m4 + m5 = 180, which proves that the interior angles of a triangle have a sum of 180 degrees.
What is interior angles of a triangle?Interior angles of a triangle are the angles formed inside a triangle at each of its vertices. The sum of these angles is always 180 degrees in a Euclidean plane.
This statement can be used because lines l and m are parallel, which means that m4 and m6 are corresponding angles and are congruent. This means that m4 = m6. Also, m5 and m4 are alternate interior angles, which means that they are congruent as well.
we can substitute m6 with m4 in the first equation to get:
m4 + m5 + m4 = 180
2m4 + m5 = 180
Therefore, the equation simplifies to:
2(180 - m5) + m5 = 180
360 - 2m5 + m5 = 180
m5 = 180 - 360 + 2m5
m5 = 2m5 - 180
m5 = 180

The two tangent with common external point theorem indicates that the relationships between the lengths of the segments are;
5·x - 8 = 8·x - 35
8·x - 35 = 5·x - 8
8·x - 5·x = 35 - 8 = 27
3·x = 27
x = 27/3 = 9
x = 97·y - 9 = 2·y + 11

5·y = 20
y = 20/5 = 4
y = 4LO = 32 - (2·y + 11)
Therefore; LO = 32 - (2 × 4 + 11) = 13
LO = 13The two tangents theorem, indicates that we get;

The opposite sides of a parallelogram are equal in length, and its diagonals bisect each other. The area of a parallelogram is equal to the product of its base (one of its sides) and its height (the perpendicular distance between the base and the opposite side).

ngozi is twice as old as Ada and Agnes 13 1/3 of ada if sum of their age is 30 how old is ngozi
The age of Ngozi if ngozi is twice as old as Ada and Agnes 13 1/3 of ada if sum of their age is 30 is 3.68 years.
How old is Ngozi?Let
Ada age = x
Agnes age = 13 1/3x
Ngozi age = 2x
30 = x + 13 1/3x + 2x
30 = 3x + 40/3x
30 = 49/3x
divide both sides by 49/3
x = 30 ÷ 49/3
multiply by the reciprocal of 49/3
x = 30 × 3/49
x = 1.84 years
Ngozi age = 2x
= 2(1.84)
= 3.68 years
Therefore, Ngozi is 3.68 years old

1. If each interior angle of a regular polygon is five times the exterior angle, how many sides has the polygon? x° зх°6x° 4xº 4x° 2x⁰ 2. Find the value of X in the polygon drawn above.
1. The number of sides of the polygon is 8
2. The value of x is 36
What is a polygon?A polygon can be defined as a flat or plane. The sum of a regular polygon is expressed as (n-2)180. The sum of exterior angle of a polygon is 360.
Therefore the sum of the interior is 5 times the exterior.
(n-2)180 = 5×360
180n - 360 = 1800
180n = 1800-360
180n = 1440
divide both sides by 180
n = 1440/180
n = 8
therefore the number of sides of the polygon is 8
2. The number of sides of the polygon is 6
Therefore the sum of angle in the polygon = 6-2)180 = 4× 180
= 720°
x+3x+6x+4x+4x+2x = 720
20x = 720
x = 720/20
x = 36
therefore the value of x is 36
