Answer:

Option C

Step-by-step explanation:

ΔABC and ΔDEF are similar triangles.

By the property of similar triangles, corresponding sides of the similar triangle are proportional.

\frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}

\frac{6}{DE}=\frac{6}{3}=\frac{10}{5}

\frac{6}{DE}=\frac{6}{3}

DE = 3

Perimeter of ΔDEF = Sum of measures of the sides of the triangle

                                = DE + EF + DF

                                = 3 + 3 + 5

                                = 11

Therefore, Option C will be the correct option.

What is the equation of a line with a slope of 7 and a point (1, 8) on the line?
Arturiano [62]
Y = mx + b
slope(m) = 7
(1,8)...x = 1 and y = 8
now we sub into the formula and find b, the y int
8 = 7(1) + b
8 = 7 + b
8 - 7 = b
1 = b
so ur equation is : y = 7x + 1 <===

The account balance on April 1st is $102.33. On April 15th a payment of $25.00 is made. On April 25th a purchase of $11.27 is ma
Mademuasel [1]

Answer:

Finance Charge = $1.42

New Account Balance = $90.02

Step-by-step explanation:

<em>APR (Annual Percentage Rate) = 22%</em>

Periodic Rate = 1.83% (APR/12)

<em>Beginning Balance = $102.33 </em>

<em>Payment made on 15th day = $25.00 </em>

<em>Purchase made on 25th day = $11.27 </em>

Finance Charge = (Beginning Balance - Payment made on 15th day) x Periodic Rate

Finance Charge = ($102.33 - $25.00) x 0.0183

Finance Charge = $77.33 x 0.0183

Finance Charge = $1.42

New Account Balance = Beginning Balance - Payment made on 15th day + Purchase made on 25th day + Finance Charge

New Account Balance = $102.33 - $25.00 + $11.27 + $1.42

New Account Balance = $90.02
