Answers
Answer:
2.5x=26-1
x=25/2.5
x=10
Step-by-step explanation:
Answer:
I assume you're solving for x, so the answer is 10
Step-by-step explanation:
First you isolate the x, so you need to subtract one from both sides, which results in the equation 2.5x = 25, and then you divide 25 by 2.5, which gives you x = 10

the price p of an aluminum tube is jointly proportional to its radius r and the length l. if a 12-foot pipe with 5-inch radius costs 5250 pesos, how much will be the cost of a 9-foot pipe with a 6-inch radius?
Answers
Answer:
4725 pesos
Step-by-step explanation:
The price p of an aluminum tube is jointly proportional to its radius r and the length l.
For joint variation, we have the expression:
p ∝rl
Hence
p = krl
Step 1
Solving for k
if a 12-foot pipe with 5-inch radius costs 5250 pesos,
5250 = k × 12 × 5
5250 = 60k
k = 5250/60
k = 87.5
Step 2
how much will be the cost of a 9-foot pipe with a 6-inch radius
We make use of the expression:
p = krl
p = 87.5 × 9 × 6
p = 4725 pesos
Therefore, the cost is = 4725 pesos

A fair die is rolled once. Let A be the event of rolling an even number, and let B be the event of rolling a number greater than 3. Find A ∩ B
Answers
Answer:
A ∩ B = {4, 6}
Step-by-step explanation:
A die had 6 faces
S = {1, 2, 3, 4, 5, 6}
If A be the event of rolling an even number, then;
A = {2, 4, 6}
If B be the event of rolling a number greater than 3, then;
B = {4, 5, 6}
A ∩ B are the values that are common to both sets
A ∩ B = {4, 6}

What is an equation of the line that passes through the points ( 3 , 1 ) and ( − 3 , − 7 ) ?
Answers
Answer:
y = 4/3x - 3
Step-by-step explanation:
Use this formula to find the slope first.
(y2 - y1) / (x2 - x1)
(x2, y2) --> (-3, -7)
(x1, y1) ---> (3, 1)
Now plug in:
(-7 - 1) / (-3 - 3) = -8 / -6 = 4/3
Now find the y intercept by plugging any points to y= 4/3x + b
I will use (3, 1).
1 = 4/3(3) + b
1 = 4 + b (subtract 4 on both sides)
-3 = b
So the formula is
y = 4/3x - 3

Edna has $900 in a savings account that earns 5% interest per year. The interest is not compounded. How much interest will she earn in1 a year?
Answers
Answer:
I= $45
Step-by-step explanation:
Giving the following information:
Edna has $900 in a savings account that earns 5% interest per year.
To calculate the interest earned, we need to use the simple interest formula:
I= P*r*t
P= principal= $900
r= interest = 0.05
t= time= 1
I= 900*0.05*1
I= $45

B Profits increased by an average of $21,600 per year
from Year 2 to Year 4.
C Profits decreased by an average of $21,600 per year
from Year 2 to Year 4.
D Profits decreased by an average of $10,600 per year
from Year 2 to Year 4.
Answers
Answer:
Step-by-step explanation:
Hi, Emily. The average rate of change can be calculated by adding all the profits together and dividing by the different profits (4 profits all together A to D) so 10,600+21,600+-21,600+-10,600= 0
0/4= 0
So we can best describe this as 0 or nothing at all as it hasnt changed from year 2 to 4.
