The circular mirror hanging on Belle's wall has a diameter of 18 inches. What is the

just olya [345]

Answer:

56.52 inches

Step-by-step explanation:

The circumference of a circle can be found using:

$c=\pi d$

We know the diameter is 18, and $\pi$ is being rounded to 3.14, so we can substitute them in.

c=3.14*18 <em>Multiply</em>

c=56.52

So, the circumference is 56.52 inches

Erica earned a total of $15,450 last year from her two jobs. the amount she earned from her job at the store was $1250 more than

dimaraw [331]

If Erica earned a total of $15450 last year from both the jobs then he earns $2840 from college if she earned 1250 more than four times the amount from college from store.

Given Total amount earned=$15450,Amount earned from store is 1250 more than 4 times earned from college.

Amount from store forms an equation.

let the amount earned from college is x.

According to question:

Amount earned from store=4x+1250

Amount earned from college=x

Total amount earned=4x+1250+x

5x+1250=15450

5x=15450-1250

5x=14200

x=14200/5

x=2840

Put the value of x in 4x+1250 to get amount earned from store=4(2840)+1250=$12610.

Hence the amount earned by Erica from college is $2840.

19. Given that angle BFC = 58°. Angle BXG = 48° and angle CBF 22 Find () 2BGX (iv) BCG (i) 2BGF (iv) ZBFG (ii) BCF H EE 58 48° D

RoseWind [281]

The unknown angles in the cyclic quadrilateral is as follows:

∠BGX = 74° (sum of angles in a triangle)

∠BGF = 180° (opposite angles of cyclic quadrilateral are supplementary)

∠BCF = 100°(sum of angles in a triangle)

∠BCG = 26°

∠BFG = 22°

<h3>Cyclic Quadrilateral</h3>

A cyclic quadrilateral has all its angles equal to 360 degrees. The sum of angles in a cyclic quadrilateral is equals to 360 degrees.

Let's find the missing angles as follows:

∠BGX = 180 - 48 - 58 = 74° (sum of angles in a triangle)

∠BGF = 180 - 100 = 80° (opposite angles of cyclic quadrilateral are supplementary)

∠BCF = 180 - 22 - 58 = 100°(sum of angles in a triangle)

∠BCG = 100 - 74 = 26°

∠BFG ≅ CBF = 22°(alternate angles)

Assessment items Jackie deposited $315 into a bank account that earned 1.5% simple interest each year. If no money was deposited

Arturiano [62]

The interest would be $14.17 so the total in the account is $329.17.

you find this by using the formula:
I = P*R*T
I =300*.015*3
I = 14.17
