Answer:30, because 12 divide by 2 is 6 then, 5 times 6 is 30

Answer:

Sarah sold 30 pairs of sneakers in 12 hours.

Step-by-step explanation:

2 hours = 5 pairs of sneakers

2 x 6 = 12

5 x 6 = 30

12 hours = 30 pairs of sneakers

At the beginning of Jack's diet, he was 257 pounds. If he lost 3 pounds per week, find his weight after
12 weeks.

Answers

Answer:

A loss of weight means we subtract from Jack's current weight.

Step-by-step explanation:

A loss of weight means we subtract from Jack's current weight. New Weight = Current Weight - Weight Loss per week * number of weeksNew Weight =257 - 3*12New Weight =257 - 36New Weight = 221

[times 12] 3 pounds= 1 week. {times 12}
36 pounds = 12 weeks

Then:

257-26=221

Answer: Jack will be 221 pounds

The terminal ray of ∠A passes through the point (−4,−6). ∠A is drawn in standard position. What is the value of cscA?

Answers

The terminal ray of an angle A passes through the origin

The value of csc(A) is -1.2

How to determine the cosine of angle A

The coordinates of the terminal ray is given as:

(x,y) = (-4,-6)

Start by calculating the length (L) of the hypotenuse

[tex]L = \sqrt{x^2 + y^2}[/tex]

So, we have:

[tex]L = \sqrt{(-4)^2 + (-6)^2}[/tex]

Evaluate the exponent

[tex]L = \sqrt{52}[/tex]

Evaluate the root

[tex]L = 7.2[/tex]

The sine of the angle A is then calculated as:

[tex]\sin(A) = \frac{-6}{7.2}[/tex]

The csc of the angle A is then calculated as:

[tex]\csc(A) = \frac{1}{\sin(A)}[/tex]

So, we have:

[tex]\csc(A) = \frac{7.2}{-6}[/tex]

[tex]\csc(A) = -1.2[/tex]

Hence, the value of csc(A) is -1.2

y=4x-8

Step-by-step explanation:

Y=mx+c

4=4(3)+c

C=-8

y=4x-8

Step-by-step explanation:

given that gradient i.e. m= dy/dx = 4.

equation passes through point (3,4)...

(Y - y1) = m (X-x1)

Y-4 = 4(X-3)

Y-4 = 4X-12

or Y = 4X-8

The initial investment is compounded annually 3.25%

That means the equation will look like this:

[tex]500(1 + 0.0325) = 500 + 500 * 0.0325[/tex]

500(1 + 0.0325) is the initial investment plus the initial investment times the percentage which in the end will give you the total amount after the investment is compounded

However, we want it compounded yearly for every year after the first initial investment

---> [tex]500(1+0.0325)^t[/tex]

Therefore the equation is the amount of money in the account after 't' year or the second choice.

Hope it helps!

p.s. the diagram I attached will help you understand where I got my equations from

Compare to the compound interest formula

[tex]\\ \rm\longmapsto P(1+r)^nt[/tex]

nt is number of years

now

P(t)=500(1+0.0325)^t

t years is correct

A pizza parlor cuts their pizzas into six pieces

c) How many slices are left over? Pls explain! :)

I will give you 50 POINTS:D

Answers

Answer:

Hi im not sure but if I was doing this this is what i would say

Step-by-step explanation:

a) since the pizza is split in 6th then the pizza would be 6/6th

b) 7/4 is equal to 1 2/4 ( not 100% simplified ) but 1 2/4 also equals to 6/6ths because 1 2/4 = 4+2=6 (not the best accurate explanation )

c) no slices are left over if joan ate 7/4th of the pizza XD

She realized that the way she treated the role of first lady would set precedents for future women. Martha had to figure out how to create an atmosphere that reflected democracy and commanded respect from the rest of the world. To accomplish this, she held a reception once a week where different people could enjoy refreshments and exchange ideas. Unlike other events, Martha's reception was representative of democracy, as it was open to different groups of people, including both men and women. Overwhelming respect for Martha led to others calling her "Lady Washington." Despite praise for her work, Martha disliked the restrictions put on her as the first lady and missed her son. In spite of these concerns, Martha did her duty and remained to support the president and her country. Her role in defining America's first ladythe figurative "Mother of America"was invaluable.Indeed, Martha Washington's roles as first lady and general's wife revealed her nurturing nature and her promotion of democratic values, making her a prime candidate for the honorable title "Mother of America."What reason does the author use to support the point that Martha Washington should be considered the "Mother of America"?
