Answer:
P5000pesos
Step-by-step explanation:
Given data
Cost of 4 tires is P10,000 pesos
we want to find the cost of two tires
Hence if 4 tires cost P10,000 pesos.
2 tires will cost x
cross multiply we have
4x= 10,000*2
4x= 20000
x= 20000/4
x= P5000pesos
Hence two tires will cost P5000pesos

Answer:
[tex]\displaystyle \frac{dS}{dt}=\frac{3}{50r}[/tex]
Step-by-step explanation:
Water is being pumped into an inflated rubber sphere at a constant rate of 0.03 cubic meters per second.
So, dV/dt = 0.03.
We want to show that dS/dt is directly proportional to 1/r.
In other words, we want to establish the relationship that dS/dt = k(1/r), where k is some constant.
First, the volume of a sphere V is given by:
[tex]\displaystyle V=\frac{4}{3}\pi r^3[/tex]
Therefore:
[tex]\displaystyle \frac{dV}{dt}=4\pi r^2\frac{dr}{dt}[/tex]
Next, the surface area of a sphere S is given by:
[tex]\displaystyle S=4\pi r^2[/tex]
Therefore:
[tex]\displaystyle \frac{dS}{dt}=8\pi r\frac{dr}{dt}[/tex]
We can divide both sides by 2:
[tex]\displaystyle \frac{1}{2}\frac{dS}{dt}=4\pi r\frac{dr}{dt}[/tex]
We can substitute this into dV/dt. Rewriting:
[tex]\displaystyle \frac{dV}{dt}=r\Big(4\pi r\frac{dr}{dt}\Big)[/tex]
So:
[tex]\displaystyle \frac{dV}{dt}=\frac{1}{2}r\frac{dS}{dt}[/tex]
Since dV/dt = 0.03 or 3/100:
[tex]\displaystyle \frac{3}{100}=\frac{1}{2}r\frac{dS}{dt}[/tex]
Therefore:
[tex]\displaystyle \frac{dS}{dt}=\frac{3}{50r}=\frac{3}{50}\Big(\frac{1}{r}\Big)[/tex]
Where k = 3/50.
And we have shown that dS/dt is directly proportional to 1/r.

What is the sticker price?
60% gross margin means they increase by the price by 60%
Multiply the purchase price by 1 + the gross margin:
16 x (1 + 0.60) = 16 x 1.60 = 25.60
The sticker price is $25.60

Which graph represents the solution to the compound inequality?
–6 < 3x – 12 ≤ 9
Answer:
second graph
Step-by-step explanation:
Solving the inequality
- 6 < 3x - 12 ≤ 9 ( add 12 to all 3 intervals )
6 < 3x ≤ 21 ( divide the intervals by 3 )
2 < x ≤ 7
The graph has an open circle at 2 and a closed circle at 7
This is represented on the second graph

The ratio of the number of boys to the number of girls at school is 4:5. If there are 120 boys, how many total students are there? (Write the number only) *
Answer:
150
Step-by-step explanation:
So first you divide 120 by 4 so you know how much times 4 was increased, 4 was increased by 30 times
Next you multiply 5 by 30 because 4 was multiplied by that much
The answer is 150 girls

Select the equation and solution for the problem. Let x represent the unknown number.
A total of 15 people on a sports team are riding in 3 vans. How many people are riding in each van if each van is carrying the same number of people?
Answer:
C
Step-by-step explanation:
So your total is 15. There are 3 vans, and we want to know how many are on each van.
3 (number of people on each van)=15
Number of people are unknown
3x=15
Divide both sides by 3 to solve for x
x=5
A rectangular glass window is divided into two equivalent right triangles by a diagonal brace. What is the length of the diagonal brace?
A. 9 inches

Step-by-step explanation: 9 square plus 12 squared equal 225 and then find the square root of 225 which equals 15
Which sequence is an example of an arithmetic sequence
Answer:
Only the third sequence is arithmetic
Step-by-step explanation:
If the sequence has a common difference, then it is arithmetic. To find the common difference, substract a term from the next term.
First sequence:
10 - 20 = -10 5 - 10 = -5 The differences are not the same, so the sequence is NOT arithmetic
Second sequence:
-6 - (-3) = -3 -18 - (-6) = -12 The differences are not the same, so the sequence is NOT arithmetic
Third sequence:
10 - 5 = 5 15 - 10 = 5 20 - 15 = 5 The differences are the same, so the sequence is arithmetic
Fourth sequence:
10 - 5 = 5 20 - 10 = 10 The differences are not the same, so the sequence is NOT arithmetic

Kristin's credit rating was lowered, and the credit card company raised her APR from 14% to 15.2%. If her average daily balance this month is x dollars, express algebraically the increase in this month's finance charge due to the higher APR. Fill in the blank 1
Answer:
0.0022x
Step-by-step explanation:
Given that,
The credit card company raised her APR from 14% to 15.2%.
Her average daily balance this month is x dollars.
We need to find the algebraically the increase in this month's finance charge due to the higher APR. It can be calculated as follows :
[tex]y=x\times \dfrac{12\%}{14}-x\times \dfrac{15.2\%}{14}\\\\=x\times \dfrac{12}{1400}-x\times \dfrac{15.2}{1400}\\\\=-0.0022x[/tex]
So, the required increase in the month's finance is 0.0022x.

0.001x
