Constance is saving money to buy a new bicycle that costs 195.75.she already 40 saved and plans to save 8 each week. how many weeks will take her to save enough money to purchase the bicycle?

20 Weeks

195.75-40=155.75

155.75÷8=19.46875

Answer

20 weeks

Step-by-step explanation:

given total is 195.75 that she needs.

she has 40

so you take 40 from the 195.7 = 155.70

you are then told she will save an additional 8 each week

and they want to know how many weeks it will take

155.70/8 a week = 19.46 weeks to gain enough money

i would imagine you will need to round up b/c it will take that 20th week to have the remaining balance

check work:

total needed 195.70

has 40

8 a week multiplied by nineteen weeks = 152.00

remaining needed is  3.70 meaning one more week

195.70

-40

-152

= 3.70

1 more week needed so 20 weeks total to save

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
