Given that (3.14*18)*17.5=3.14*(3p*17.5).Find the value of p
Answer:
The value of p = 6.
Step-by-step explanation:
Given the expression
[tex]\left(3.14\cdot \:18\right)\cdot \:17.5=3.14\left(3p\cdot \:17.5\right)[/tex]
Solving for p
[tex]\left(3.14\cdot \:18\right)\cdot \:17.5=3.14\left(3p\cdot \:17.5\right)[/tex]
switch sides
[tex]3.14\left(3p\cdot \:17.5\right)=\left(3.14\cdot \:18\right)\cdot \:17.5[/tex]
Remove parentheses: (a) = a
[tex]3.14\left(3p\cdot \:17.5\right)=3.14\cdot \:18\cdot \:17.5[/tex]
Multiply the numbers: [tex]3.14\cdot \:18\cdot \:17.5=989.1[/tex]
[tex]3.14\left(3p\cdot \:17.5\right)=989.1[/tex]
Multiply both sides by 100
[tex]3.14\cdot \:3p\cdot \:17.5\cdot \:100=989.1\cdot \:100[/tex]
Refine
[tex]16485p=98910[/tex]
Divide both sides by 16485
[tex]\frac{16485p}{16485}=\frac{98910}{16485}[/tex]
Simplify
[tex]p=6[/tex]
Therefore, the value of p = 6.

At a swim meet 20 medals were a warded. Four were gold metals 45% of the metals were silver the rest were bronze. What percent of the medals awarded were bronze
Answer:
35%
Step-by-step explanation:
To figure out the percentage of bronze medals, we must figure out the percentages of the gold and silver medals first.
We already know that 45% of the medals were silver.
We know that 4 of the 20 medals were gold.
4/20 as a percentage would be 20/100, or 20%.
So, 20% of the medals were gold, and 45% of them were silver.
45% + 20% = 65%
100% - 65% = 35%
So, 35% of the medals awarded were bronze.

The area of a rectangular fence is 500 square feet. If the width of the
fence is 20 feet, then find its length.
Answer
Here the area and the width of the rectangular fence are given. We have to find length of the fence.
( diagram )
The area A of a rectangle is given by the formula A=lw where l is the length and w is the width.
Given that area is 500 square feet and width is 20 feet.
Substituting values in formula,
⇒500=l×20
⇒20/500
= 20/1×20
[ Dividing both sides by 20 ]
⇒l=25 feet
∴ length of rectangular fence is 25 feet.
Hence, the answer is 25.

the end of 8 months?
Answer:
The baby weighed 14.5 pounds at the end of 8 months
Step-by-step explanation:
Proportions
We know a baby weighed 7.25 pounds at birth.
It's given at the end of 8 months, the baby weighed twice its birth weight.
This means the baby weighed 2*7.25 = 14.5 pounds at the end of 8 months.
The baby weighed 14.5 pounds at the end of 8 months

Write an inequality for the situation. Use x as your variable.
Mrs. Treble charges her music students $25 per lesson plus a recital fee of $30. How many lessons can Melinda take if she wants to pay less than $155?
Answer:
Inequality: 25x + 30 < 155
Step-by-step explanation:
25x is the cost per lesson. 30 is the recital fee. 155 is the total cost. We used the < sign because she has to pay LESS than $155.
Solve...
25x + 30 < 155
Subtract 30 on both sides...
25x < 125
Divide 25 on both sides...
x < 5
THATS NOT YOUR ANSWER YET Always make sure to plug in the answer you got BEFORE inputting it.
Plug in 5 for x...
25 ( 5 ) + 30 < 155
125 + 30 < 155
155 < 155
You know that she wants to spend LESS than $155, when she takes 5 lessons, as shown above, she spends exactly $155, your answer would be 4 because she spends less than $155 when taking 4 classes, but exactly $155 when taking five.
Really hope this helps! :)

The length of a rectangular birthday party invitation is 1 inch less than twice its width. The area of the invitation is 15 square inches.
The length of a rectangular birthday party invitation is 9 inch.
The length of a rectangular birthday party invitation is 1 inch less than twice its width.
Area of the invitation 15 square inches.
what is the area of the rectangle?
A=length× width
That is,the area of a rectangle is length times width.
let x be the width rectangle
width = x
length = 2x - 1
[tex]Area= 15 square inches[/tex]
Using these variables, set up the equation for area.
x(2x - 1) = 15
Solve the equation for x.
[tex]2x^{2} - x = 15[/tex]
Subtract 21 on both sides of the equation.
[tex]2x^{2} - x - 15=0[/tex]
Which method we use to factor the polynomial?
FOIL method
Factor using FOIL, if possible.
(2x +5)(x - 5) = 0
Set the factors equal to zero and solve for x.
2x = -5 and x - 5 = 0
x =- 5/2 or x = 5
x =- 2.5 or x=5
Since we cannot accept a negative value for dimensions, we accept the positive value of x:
x = 5
Therefore,
Length = 2(5) - 1
Length = 10-1
Length = 9
Therefore we get the length is 9 inch
