2. Emmalyn has read 14 out of her 22 books. Write a proportion that you could use to find the percent of her books she has read. Then find the percent. 3. For small business Saturday, a store decides to markup products by 54%. If the store bought each item for $29.25, what is the resale price for each item?

4. Jack took a loan out for $8000 to buy a car. At the end of 5 years, he pays back the principal, plus $1200 simple interest. What was the interest rate?

5. Rachel and Zach go out to eat for lunch. If their food and beverage cost $22.50 and there is an 9% tax on the meal, how much is the bill? (what is the total for what they consumed and tax?)
If They left a 18% tip, how much did they spend for lunch? (tip and bill included)

6. Jamie found that about 80% of his 80 classmates at school like football. How many classmates like football?
He then found that 60% of his 150 relatives like football. Does he have more classmates or relatives that like football?

7.If airpods are normally $129.99 and are on sale for 20%off, how much are they on sale for?

8. Mrs. Collins is writing a paper that needs to be 4000 words. If she is 60% of the way done how many more words does she need to add to the paper?

9. Sally took out a loan for 4 years at an interest rate of 4%. If she borrowed $5000, how much in total does she have to pay back?

10.Write 4% as a decimal.

the answer is 24

step-by-step explanation:

la parábola es el lugar

geométrico en el cual los puntos tienen una distancia idéntica, equidistantes,

de un punto denominado foco, f, y una recta denominada directriz

el radio vector de una

parábola es el segmento que existe entre un punto cualquiera y el foco.

por la ecuación se observa

que la parábola abre hacia la derecha, por lo cual podemos usar las siguientes fórmulas

la ecuación ordinaria de la

parábola es y^2 = 4px, donde p es la longitud desde el vértice de la parábola al

foco.

la fórmula de la directriz

es x + p = 0

resolviendo:

y^2-9x = 0

y^2 = 9x

4p = 9, entonces p = 9/4

entonces el foco tendrá la

coordenada f(9/4,0)

la directriz vendrá

expresada por

x + p = 0

x = -p

x = -9/4

el problema indica que la

ordenada es igual a 6, entonces

(6)^2=9x

x = 36/9

x = 4

entonces el punto al cual

hay que obtener la distancia será p(4,6)

calculando se tendrá: pf = 

pf = 6,25 u

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
