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.

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

Answer:

B. 45.23 cm

Step-by-step explanation:

perimeter of the figure

[tex] =\frac{1}{2}\pi d+d[/tex]

[tex] =\frac{1}{2}\times 3.14\times 17.6 +17.6[/tex]

[tex] =\frac{1}{2}\times 55.264 +17.6[/tex]

[tex] =27.632 +17.6[/tex]

[tex] =45.232[/tex]

[tex] =45.23\: cm[/tex]

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

Answer:

491.52

Step-by-step explanation:

1500×.80×.80×.80×.80×.80=491.52

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.

Answer:

The system of equations will be:

p(x) = 0.9x + 6.80

m(x) = 0.65x + 7.30

Hence, option D is correct.

Step-by-step explanation:

The slope-intercept form of the linear equation

f(x) = mx+b

where

Analyzing Papa's Pizzeria p function:

Given that A large pizza at Papa's Pizzeria cost $6.80 plus $0.90 for each topping.

As the fixed cost or initial cost of Papa's Pizzeria is $6.80.

As Papa's Pizzeria offers $0.90 for each topping.

We know that the slope-intercept form of the linear equation

f(x) = mx + b

In this case, the function is m.

now substituting m = 0.9 and b = 6.80 in the slope-intercept form of linear equation

p(x) = 0.9x + 6.80

Thus, the equation that represents the Papa's Pizzeria topping and cost model.

p(x) = 0.9x + 6.80

Analyzing Papa's Pizzeria p function:

Given that a large cheese pizza at Mama's Pizza costs $7.30 plus $0.65 for each topping.

As the fixed cost or initial cost of Mama's Pizza is $7.30.

As Mama's Pizza offers $0.65 for each topping.

We know that the slope-intercept form of the linear equation

f(x) = mx + b

In this case, the function is m.

now substituting m = 0.65 and b = 7.30 in the slope-intercept form of linear equation

m(x) = 0.65x + 7.30

Thus, the equation that represents the Mama's Pizza topping and cost model.

m(x) = 0.65x + 7.30

Conclusion:

The equation that represents the Papa's Pizzeria topping and cost model.

p(x) = 0.9x + 6.80

The equation that represents the Mama's Pizza topping and cost model.

m(x) = 0.65x + 7.30

Thus, the system of equations will be:

p(x) = 0.9x + 6.80

m(x) = 0.65x + 7.30

Hence, option D is correct.

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.

Answer:

$0.45

Step-by-step explanation:

Discount is 15% so that means you only need to pay (100 - 15)% = 85% of the total cost of the eraser.

Cost with discount = $0.50 × 85% = $0.50 × 0.85 = $0.43.

Sales tax is 6.25% so you will pay 6.25% × $0.43 = $0.03 for sales tax.

Total cost with sales tax = $0.43 + $0.03 = $0.45.

It is said that a pitcher pitches a ball to a hitter. The ball is hit towards center field, hits the center field fence, then drops to the ground.

When the pitcher throws the ball, it advances towards the batter. The ball has a particular height during its action, and its height remains constant. The red line depicts this motion.

After the batter strikes the ball, it swiftly ascends to its maximum height. The blue line depicts this motion.

When the ball attains its maximum height, it strikes the fencing and loses elevation. The height is reduced to zero. The green line in the graph depicts this.
