Answer:
Solving the equation [tex]15 = 3n + 6p[/tex] for variable n we get [tex]\mathbf{n=5-2p}[/tex]
Step-by-step explanation:
We need to solve the equation [tex]15 = 3n + 6p[/tex] for variable n
Solving:
[tex]15 = 3n + 6p[/tex]
Subtract both sides by 6p
[tex]15-6p = 3n +6p -6p\\15-6p=3n[/tex]
Switch sides of equality
[tex]3n=15-6p[/tex]
Divide both sides by 3
[tex]\frac{3n}{3} =\frac{15-6p}{3}\\n=\frac{3(5-2p)}{3}\\n=5-2p[/tex]
So, solving the equation [tex]15 = 3n + 6p[/tex] for variable n we get [tex]\mathbf{n=5-2p}[/tex]
A basket contains 40 mangoes out of which 22 are good . Find the percentage of the mangoes that are bad
Answer:
45% of the mangoes are bad.
Step-by-step explanation:
Given that:
Number of mangoes in basket = 40
Number of good mangoes = 22
Number of bad mangoes = Total mangoes - Good mangoes
Number of bad mangoes = 40-22
Number of bad mangoes = 18
Percent of bad mangoes = [tex]\frac{bad\ mangoes}{total\ mangoes}*100[/tex]
Percent of bad mangoes = [tex]\frac{18}{40}*100[/tex]
Percent of bad mangoes = 0.45*100 = 45%
Hence,
45% of the mangoes are bad.
Escribe la ecuación: Un balón de baloncesto cuesta 10€ menos que uno de fútbol. Si 10 balones de fútbol y 4 de baloncesto cuestan 310€.
Responder:
14x - 40 = 310
Explicación paso a paso:
Dado que:
El baloncesto cuesta 10 € menos que un balón de fútbol
10 balones de fútbol y 4 de baloncesto cuestan 310 €
Para formar una ecuación:
Deje que el costo de:
Balón de fútbol = x
Costo del baloncesto = x - 10
Por lo tanto,
Costo de 10 balones de fútbol = 10 * x = 10x
Costo de 4 pelotas de baloncesto = 4 * (x - 10) = 4x - 40
Coste total :
Coste del balón de fútbol + coste del baloncesto = 310 €
10x + 4x - 40 = 310 €
14x - 40 = 310
14x = 310 + 40
14 veces = 350
x = 25 € = coste del balón de fútbol
Coste del baloncesto = 25 € - 10 € = 15 €

When will Peter's baseball hit the ground? Use mathematical evidence to explain your answer.
Question:
The height of Peter’s baseball is given by the graph below (See attachment)
When will Peter’s baseball reach the highest height? What is the height? When will Peter’s baseball hit the ground? Use mathematical evidence to explain your answer.
Answer:
Peter's baseball reached the maximum height at 1.5 secondsPeter's baseball hit the ground at 4 secondsStep-by-step explanation:
The (a) & (b) will be answered by making reference to the attachment.
Solving (a): Time to reach maximum height
The height is plotted at the vertical axis while the time taken is at the horizontal axis.
From the attachment; the following details can be observed
The maximum height is at 90ftWhen the maximum height is traced to the horizontal axis, the corresponding time is 1.5sUsing function notations, this can be represented as:
[tex]f(1.5) = 90[/tex]
And the interpretation is that:
Peter's baseball reached the maximum height at 1.5 seconds
Solving (b): Time to hit the ground
The interpretation of this question is to solve for the x intercept of the graph.
From the attachment; the following details can be observed
The ground is at 0 feetThe corresponding time at 0 feet is 4sUsing function notations, this can be represented as:
[tex]f(4) = 0[/tex]
And the interpretation is that:
Peter's baseball hit the ground at 4 seconds

If the product of the extremes is 8,then the geometric mean is
~2
~4
~2(square root sign)2
The geometric mean of two numbers is the square root of their product:
[tex]GM(a,b)=\sqrt{ab}[/tex]
So, if the product is 8, the geometric mean is [tex]\sqrt{8}=2\sqrt{2}[/tex]
What are two numbers that multiply to the value on top and add to the value on bottom
is this correct?
a * b = -70
a + b = -9......a = -9 - b
b(-9 - b) = -70
-b^2 - 9b + 70 = 0
(-b + 5)(b + 14) = 0
-b + 5 = 0
5 = b
b + 14 = 0
b = -14
ur numbers are -14 and 5
-14 * 5 = -70
-14 + 5 = -9
Antwan Campbell earns $494 per week. He is married and claims 1 child as a dependent. The state tax rate is 2.25% of taxable income. What amount is withheld from his weekly pay for state income tax?
Answer:
$12.35
Step-by-step explanation:
Amount earned by Campbell per week = $494
Tax rate = 2.25 %
Amount withheld = 2.25% of his earning;
Amount withheld = 2.25 % of 494
Amount withheld = 0.025 * 494
Amount withheld = $12.35
Hence the amount withheld from his weekly pay for state income tax is $12.35
A triangle has three vertices located at A(-1, 2), B(-1, 5), and C(-4, 2). List the ordered pairs of the triangle after it has been translated four units to the right, reflected over the x-axis, and then rotated 90oclockwise about the origin.
Answer:
A’ is (-2,-3)
B’ is (-5,-3)
C’ is (2,0)
Step-by-step explanation:
We have three operations to perform;
a) translate 4 units right
means that we add 4 to the x-coordinate
b) Reflect over x-axis
If we reflect over x-axis;
(x,y) becomes (x,-y)
c) Rotate 90 degrees clockwise
(x,y) becomes (y,-x)
We have the following as the solution;
A( - 1,2)
Add 4 to x-coordinate
(3,2)
Reflect over x-axis
(3,-2)
Rotate 90 degrees clockwise
(-2,-3)
for B (-1,5)
Add 4 to x-coordinate
(3,5)
Reflect over x-axis
(3,-5)
Rotate
(-5,-3)
C; (-4,2)
Add 4 units to x-axis
(0,2)
Reflect
(0,-2)
Rotate
(2.0)

Manuel bought a 3/5 of a pound of clay for the students in his pottery class. He then divided the clay into 6 equal pieces for his students to use for making vases and pots. How much did each piece weigh?
Group of answer choices
Answer:
Each piece weighed 1/10 of a pound.
Step-by-step explanation:
We have 3/5 of a pound and we want to divide it by 6 equal pieces for each student. 6 equal pieces is the same as 6/1.
In order to divide 3/5 by 6/1 we need to invert the 6/1 and multiply. So, it becomes 3/5 x 1/6. First, we multiply the numerators: 3x1=3 then we multiply the denominators: 5x6=30. The result is 3/30, which can be reduced by dividing both the numerator and denominator by 3. 3/3=1 and 30/3=10. So, the result is 1/10.
