Anne Richards purchased two slippers at one price and three pajamas at another price. Let s = the price of each slipper and p = the price of each pajama. Each slipper
cost $12. How much did each pajama cost if the total purchase price was $120?
Each pajama cost $. (Simplify your answer.)

Answers

Answer:

[tex]E[/tex]ach pajama costs $32

Step-by-step explanation:

So, the said person bought:

2 slippers at a price, 3 pajamas at another price. (The prices are unknowns, s, and p)

Each slippers cost $12

We are to find the cost of each pajama, where the total purchase price is $120

With the given conditions, we formulate an equation: 2s + 3p = 120

Since s = 12, we replace for the value of s in the equation. s becomes 2 × 12 = 24.

The new equation is then: 24 + 3p = 120, where we are to find the value of p.

Collect like terms: 3p = 120 - 24 3p = 96

Divide both sides of the equation by 3 to find the value of p: 3p/3 = 96/3 p = 32

Therefore, the price of each pajama is $32

Thankyou!!

Answers

Answer:

AB = 45.688 metres

Step-by-step explanation:

* i used a scientific calculator for my working. i am not sure if calculators are permitted for your exam on Wednesday *

AB = AD + DB

⭐AB = 16.5 + DB

Thus, we need to find DB in order to solve for AB.

First, I utilized the triangle sum theorem to find ∠BDC:

[tex]< BDC + < DCB + < B = 180\\ < BDC + 59 + 90 = 180\\ < BDC + 149 = 180\\ < BDC = 31[/tex]

Then, I utilized the linear pair sum to find ∠ADC:

[tex]< ADC + < BDC = 180\\ < ADC + 31 = 180\\ < ADC = 149[/tex]

Next, I utilized the triangle sum theorem to find ∠DAC:

[tex]< DAC + < ADC + < ACD = 180[/tex]

[tex]< DAC + 149 + 10 = 180[/tex]

[tex]< DAC + 159 = 180[/tex]

[tex]< DAC = 21[/tex]

After, I utilized the law of sines to find DC:

[tex]\frac{sin10}{16.5} = \frac{sin21}{DC}[/tex]

[tex]DCsin10 = 16.5sin21[/tex]

[tex]DC = \frac{16.5sin21}{sin10}[/tex]

[tex]DC = 34.052[/tex]

Then, I utilized the sine function to find DB for ΔBDC:

[tex]sin(59) = \frac{DB}{34.052}[/tex]

[tex]34.052sin(59) = DB[/tex]

[tex]29.188 = DB[/tex]

Finally, I substituted DB into our original equation for AB:

[tex]AB = AD + DB[/tex]

[tex]AB = 16.5 + 29.188[/tex]

[tex]AB = 45.688 metres[/tex]

Good luck on your exam on Wednesday! :-)

What are trigonometric identities?

Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are numerous distinctive trigonometric identities that relate to a triangle's side length and angle.

Given that the angle BCD is 59 and the angle BCA is 69. The height will be calculated as,

tan(59) = BD / BC

BC = BD / tan(59)

BC = 0.6BD

tan(69) = AB / BC

tan(69) = ( 16.5 + BD ) / BC

BC = 0.38( 16.5 + BD )

Equate the values of BC,

0.6BD = 0.38 ( 16.5 + BD )

0.6BD = 6.27 + 0.38BD

0.22BD =6.27

BD = 28.5 meters

The height of the pole is,

AB = AD + DB

AB = 16.5 + 28.5

AB = 45 meters

E. 0.8 (0.2)^7

Answers

The probability of needing to catch 8 fish to get the first salmon is D) 0.2 (0.8)^7.

How to calculate probability of needing to catch 8 fish to get the first salmon?

Given that he probability of fishing a salmon in a certain river is 20% i.e. 0.2. Now, the probability of not getting a salmon will be

1 - probability of not getting salmon  = 1 - 0.2 = 0.8.

So, the first fish should be salmon and the others should not be salmon. So, the required probability of independent events can be calculated as,

P =0.2×0.8×0.8×0.8×0.8×0.8×0.8×0.8×0.8

P = 0.2× (0.8)^7

Some values of f(x, y) are given below. Write out the terms of a Riemann Sum (using four squares) that gives an upper estimate of r 4 0 r 4 0 f dx dy.

Answers

To find a Riemann sum that gives an upper estimate of the double integral, we need to divide the region of integration into small subregions (in this case, squares) and take the maximum value of f(x, y) over each subregion.

The Riemann sum will then be the sum of the areas of the subregions times the maximum value of f(x, y) over each subregion.

For example, if we divide the region of integration into four squares, the Riemann sum would be given by:

Riemann sum = (area of first square) * (maximum value of f(x, y) in first

                           square) + (area of second square) * (maximum value of

Martha has a $200 deductible and 20% co-payment on her health
insurance. Last year she had $6,500 in medical bills. What was
Martha's out-of-pocket expense?

Answers

Answer:

Step-by-step explanation:

To solve this problem, we need to calculate Martha's out-of-pocket expenses, and the total amount of money she had to pay for her medical bills.

First, we need to calculate the amount of money Martha had to pay toward her deductible. Since her deductible is $200, this is the amount she had to pay out of pocket.

Next, we need to calculate the amount of money Martha had to pay toward her co-payment. Since her co-payment is 20%, we can calculate this by multiplying her medical bills by the co-payment rate: $6,500 x 0.2 = $1,300.

To find Martha's total out-of-pocket expense, we can add the amount she paid towards her deductible ($200) and the amount she paid towards her co-payment ($1,300):

$200 + $1,300 = $1,500

Therefore, Martha's out-of-pocket expense was $1,500.

Final answer:

Martha's insurance required her to pay a $200 deductible and a 20% co-payment on the remaining balance of her medical bills. After paying the deductible, she pays 20% of the remaining $6,300 which is $1,260. So, Martha's total out-of-pocket expense was $1,460.

Explanation:

Martha's health insurance plan includes a $200 deductible and a 20% co-payment. The deductible is the amount Martha has to pay before the insurance company starts to pay. In this case, Martha first pays a $200 deductible from her $6,500 medical bills, which leaves her with $6,300 to be covered by insurance and her co-payment. The 20% co-payment means Martha is responsible for paying 20% of the remaining $6,300. To calculate this, we multiply $6,300 by 0.20 (20%), which equals $1,260. Therefore, Martha's total out-of-pocket expense for her medical bills last year was the $200 deductible plus the $1,260 co-payment, equalling $1,460.

If the opposite corners of the rectangle ABCD are A (5, 3) and C (10, 1) and the equation of side BC is x-2y=8, find the equations of the other three sides. You must show your work and explain why you are doing it. (Note: opposite side of a rectangle are parallel and consecutive sides are
perpendicular)

Answers

Answer:

Equation of side AB:

We know the coordinates of A and B, so we can use the point-slope form to create the equation of the line:

y - 3 = (3/5)(x - 5)

y - 3 = 3/5x - 15/5

5/3y - 15/3 = x - 5

5/3y - x = -15/3 + 5

5/3y - x + 15/3 = 5

5/3y - x + 15/3 = 0

Equation of side AB: 5/3y - x + 15/3 = 0

Equation of side DC:

We know the coordinates of C and D, so we can use the point-slope form to create the equation of the line:

y - 1 = (2/5)(x - 10)

y - 1 = 2/5x - 20/5

5/2y - 10 = x - 10

5/2y - x = -10

5/2y - x - 10 = 0

Equation of side DC: 5/2y - x - 10 = 0

Equation of side BD:

We know the equation of side BC (x - 2y = 8) and that consecutive sides are perpendicular, so we can use the slope-intercept form to find the equation of line BD:

Slope of BC = -2/1

Slope of BD = -1/-2 = 1/2

y = (1/2)x + b

We can use the coordinates of B to find b:

1 = (1/2)(8) + b

2 = 4 + b

b = -2

Equation of side BD: y = (1/2)x - 2

A total of $28000 is invested in 2 municipal bonds that pay 5.75% and 7.25% simple interest. The investor wants an annual interest income of $1790 from the investments. What amount should be invested in the 5.75% bond?

Answers

Answer:

$16,000

Step-by-step explanation:

Simple Interest Formula

I = Prt

where:

I = Interest accruedP = Principal amountr = Interest rate (in decimal form)t = Time (in years)

Let investment 1 be the bond that pays 5.75% simple interest.

Let investment 2 be the bond that pays 7.25% simple interest.

Given:

P₁ + P₂ = $28,000r₁ = 5.75% = 0.0575r₂ = 7.25% = 0.0725t = 1 year

Create two equations for the interest from both investments.

Interest from Investment 1

[tex]\implies \sf I_1=P_1 \cdot 0.0575 \cdot 1[/tex]

[tex]\implies \sf I_1=0.0575\:P_1[/tex]

Interest from Investment 2

[tex]\implies \sf I_2=P_2 \cdot 0.0725 \cdot 1[/tex]

[tex]\implies \sf I_2=(28000-P_1)0.0725[/tex]

[tex]\implies \sf I_2=2030-0.0725\:P_1[/tex]

Given that the sum of the interest from both investments is $1,790:

[tex]\implies \sf I_1+I_2=1790[/tex]

[tex]\implies \sf 0.0575\:P_1+2030-0.0725\:P_1=1790[/tex]

[tex]\implies \sf -0.015\:P_1=-240[/tex]

[tex]\implies \sf P_1=16000[/tex]

Therefore, $16,000 should be invested in the 5.75% bond.

Check:

[tex]\implies \sf I_1=16000 \cdot 0.0575 \cdot 1 = 920[/tex]

[tex]\implies \sf I_2=12000 \cdot 0.0725 \cdot 1 = 870[/tex]

What is the equation in slope-intercept form of the line that crosses the x-axis at 14 and is parallel to the line represented by y= -2/3x+6

Answers

The equation in slope intercept for the given line is  y = -2/3x - 28/3.

What is Slope ?

The slope or gradient of a line in mathematics is a number that indicates the line's steepness and direction.

Given,  the line crosses the x-axis at 14 and is parallel to the line represented by y= -2/3x+6.

We know that two parallel lines always have the same slope.

We can say that the line has coordinate as (14,0) and slope (m) as -2/3.

We know that the slope-intercept form of the line is,

                    y= mx + b

Now, We put x=14, y=0 and m=-2/3 in equation above,

We get, 0 = -2/3 × 14 + b

             b = -28/3

So, the slope intercept form will be :

Leila works mowing lawns and babysitting.She earns $8.20 an hour for mowing and $7.90 and hour and babysitting.How much will she earn for 7 hours of mowing and 4 hours of babysitting?

Answers

Answer: 89

Step-by-step explanation:

1 hr of mowing = 8.20 dollars

1 hr of babysitting = 7.90 dollars

7 hrs of mowing = 8.20 x 7 = 57.4 dollars earned

4 hrs of babysitting = 7.90 x 4 = 31.6 dollars earned

Total amount she has earned = 57.4 + 31.6 + = 89 dollars

What is the 95% confidence interval for this population proportion? Answer choices are rounded to the hundredths place.

Answers

The 95% confidence interval for this population proportion is (0.10, 0.23).

What is a confidence interval?

A confidence interval is a range of values that are constrained by the statistic's mean and that are likely to include an unidentified population parameter. The proportion of likelihood, or certainty, that the confidence interval would include the real population parameter when a random sample is drawn several times is referred to as the confidence level.

Sample size n = 125

number of people who planned to take an extended vacation = 21

sample proportion p = 21/125 = 0.168

Confidence level = 0.95

significance level α = 1-0.95 = 0.05

Z score =[tex]Z_{\alpha 2}[/tex] = Z(0.05) = 1.96, from Z table.

The confidence interval for population proportion is-

p±[tex]Z_{\alpha 2}[/tex] x √{p(1-p)}/n =0.168±1.96 x 0.168 x √{(1-0.168)}/125

                        =0.168±1.96 x 0.0334

                        =0.168±0.0655

                        =(0.1025, 0.2335)

                        =(0.10, 0.23)

Therefore, the confidence interval is (0.10, 0.23).

Lines PQ and BC are parallel.
What is the value of x ?

Answers

Answer:

x = 40

Step-by-step explanation:

since lines PQ and BC are parallel , then

∠ BCQ and ∠ AQP are corresponding angle and are congruent , that is

∠ BCQ = 80°

the sum of the 3 angles in Δ ABC = 180° , then

x + 80 + 60 = 180

x + 140 = 180 ( subtract 140 from both sides )

x = 40
