Answer:

$25

Step-by-step explanation:

An = 10 + An-1

At the end of 4th week ; amount repaid = $55

A4 = 10 +

An = a + (n - 1)d

n = 4

A4 = 10 + (4 - 1)d

55 = 10 + 3d

55 - 10 = 3d

45 = 3d

d = 15

Hence, at the end of first week :

A1 = a + d

$10 + $15

= $25

Karina and Perry are cleaning up litter in the park for community service hours. Karina and Perry both claim they have covered t

alexgriva [62]

Answer:

Perry's claim is correct while Karina is incorrect

Step-by-step explanation:

Question is incomplete (See Attachment)

First, we need to determine the area covered by Karina and Perry

For Karina, there are 9 square boxes each of which has an area of 1 unit sq

So:

$Karina = 9 * 1\ unit^2$

$Karina = 9\ unit^2$

For Perry:

There are 18 square boxes, each of which has an area of 1 unit sq.

So:

$Perry = 18 * 1\ unit^2$

$Perry = 18\ unit^2$

Comparing both areas, we can conclude that Perry's claim is correct while Karina is incorrect

As given

Jeff and Darius are trying to gain weight for the football team.

Jeff weighs 120 pounds and is gaining ten pounds per month.

Darius weighs 150 pounds and is gaining 4 pounds per month.

m = represented the number of months will taken by the Jeff to weigh the same as Darius .

Than the equation become in the form

120 + 10m = 150 +4m

150 - 120 = 10m - 4m

30 = 6m

$m = \frac{30}{6}$

m = 5 months

Therefore in 5 months will it take for Jeff to weigh the same as Darius.

Geometry question on finding x.

Dmitrij [34]

Answer:

$x =63^o$

Step-by-step explanation:

Given :-

$\text{ $\overline{MN} $ and $\overline{ML}$ are tangents .}$

We know that the tangents are perpendicular to the radius at the point of contact . And here OLMN is a quadrilateral. Also we know that , the angle sum property a triangle is 360° .

According to question :-

$\implies x + 117^o + 90^o +90^o = 360^o \\\\\implies x + 297^o = 360^o \\\\\implies x = 360^o - 297^o \\\\\implies x = 63^o$
