The Hoffman family has bought one pizza on Friday night every week for the last 10 years. How many pizzas have they bought on Friday nights? Enter your answer in the box.

520 pizzas

Step-by-step explanation:

1 year = 52 weeks

Meaning the number of Fridays in a week = 52 Fridays

We are told that: The Hoffman family has bought one pizza on Friday night every week for the last 10 years.

Hence, the number of pizzas they bought in 1 year

= 52 Friday × 1 pizza

= 52 pizzas

For the last 10 years

= 52 pizzas × 10

= 520 pizzas

Hence, they have bought 520 pizzas in the last 10 years

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

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
