A pair of sunglasses is on sale for $17. Last week, the sunglasses were marked at a regular price of $20. What was the percent of change?

Answers

Answer 1

Answer:

15%

Step-by-step explanation:

17/20 the 17 is the part, and the 20 is the whole

17/20 = x/100

cross multiply

17*100= 1,700 divide by 20

=85

The price reduced to 85% the original price, but to find out how much it changed, you have to subtract the part from the whole meaning

100% - 85% = 15%

find constants p and q such that x^4-2x^3-x^2+2x+10=(x^2+px+5)(x^2+qx+2)

Answers

Answer:

p = -4 q = 2

Step-by-step explanation:

Expand the brackets ( yes the entire thing).group together the values with same co-effiecients; like (q+p)x^3 etc etc.equate the co-effiecients on the left hand side to the now grouped ones on the right, for example [x^3]: -2x^3= (q+p)x^3, the x^3 cancels and ull get an equation only in terms of p and q. do the same for [x] and ull get an equation with only q, solve this and get the value for q [q = 2].sub in this value for the [x^3] equation and ull get an answer for p [p= -4].

Simplify the following using BODMAS
3p + [5 − (2p + 7q)]

Answers

Hopes this helps if it don’t than sorry:

Answer: p + 5 - 7q

Answer:

So frist thing is frist, since we are using the BODMAS. We should start with the numbers in the brackets, simplify the small bracket frist.

3p + [ 5 - (2p + 7q)]

= 3p + (5 - 2p - 7q)

= 3p - 2p - 7q + 5

= p - 7q + 5

Quadrilateral ABCD is inscribed in this circle.
What is the measure of angle A?
Enter your answer in the box

Answers

Answer:

m∠A = 116°

Step-by-step explanation:

For better understanding of the solution, see the attached figure of the problem :

The quadrilateral ABCD is inscribed in a circle, Thus the quadrilateral ABCD is a cyclic quadrilateral.

Also, Sum of opposite angles of a cyclic quadrilateral is supplementary.

Now, m∠A = (x - 36)°, m∠B = 28° and m∠D = x°

But, since the sum of opposite angles is 180°

⇒ 28° + x° = 180°

⇒ x = 180 - 28

⇒ x = 152

So, m∠A = (x - 36)°

⇒ m∠A = (152 - 36)°

⇒ m∠A = 116°

Candice drives a total of 48 miles each day to work and get back home. She works five days a week. Her car gets 21 miles per gallon of gas. About how many gallons of gas does she need to drive to work and back home each week

Answers

Answer:

Total gallon of fuel used = [tex]11.428[/tex] gallons

Step-by-step explanation:

Given -

The total distance travelled by car in one gallon of gas = 21 miles

Total distance travelled each day = 48 miles

Number of days days in a week in which Candice drive is 5 days

Total miles travelled per week = [tex]48*5[/tex] = 240 miles

Total gallon of fuel used = [tex]\frac{240}{21} = 11.428[/tex] gallons

In January Todd was able to lift 127 1/2 lb. In February he could lift 135 lb, and in March he could lift 142 1/2 lb. If he continues at this rate what will Todd be able to lift in July?

Answers

Answer:

172 1/2 lb

Step-by-step explanation:

Determine the rate of change per month = lifts lifted in march - lift lifted in February

142 1/2 - 135 = 7 1/2

Determine the number of months from march to July = 4

increase in weight he would be able to carry in 4 months = 7.5 x 4 = 30 lb

weight he would be able to carry in april = 30 + 142 1/2 = 172 1/2
