Answer:

Step-by-step explanation:

First, you must find the actual decrease in temperature.

Decrease = Yesterday's temperature - Today's temperature

Decrease = 80 - 75

Decrease = 5 degrees

Now, find the percentage decrease.

% Decrease = Actual decrease / Yesterday's temperature x 100

% Decrease = 5/80 x 100

% Decrease = 0.0625 x 100

% Decrease = 6.25 %

So, the percent decrease in high temperature from yesterday to today is 6.25%

Each pair of polygons is similar. Find each missing side measure. two polygons 12 on top 5 on bottom second polygon 48 on top x

Firlakuza [10]

Answer:

$x = 20$

Step-by-step explanation:

Given

First Polygon:

$Top = 12$

$Bottom =5$

Second Polygon

$Top = 48$

$Bottom =x$

Required

Find x

Since both polygons are similar, then:

$Ratio = Top:Bottom$

For the first:

$Ratio = 12:5$

For the second

$Ratio = 48:x$

Equate both ratios

$12:5 = 48:x$

Express as fraction

$\frac{12}{5} = \frac{48}{x}$

Cross Multiply

$12 * x = 48 * 5$

Solve for x

$x = \frac{48 * 5}{12}$

$x = \frac{240}{12}$

$x = 20$

9. Suppose you take out a car loan for $9999 for 4 years at a 7.5% interest rate. What is your

Alekssandra [29.7K]

Answer:

The monthly payment is $241.76.

Step-by-step explanation:

Given : Suppose you take out a car loan for $9999 for 4 years at a 7.5% interest rate.

To find : What is your monthly payment ?

Solution :

The formula to find monthly payment is

$M=\frac{\text{Amount}}{\text{Discount factor}}$

Discount factor is $D=\frac{1-(1+i)^{-n}}{i}$

Substitute in the formula,

$M=\frac{A}{\frac{1-(1+i)^{-n}}{i}}$

$M=\frac{A\times i}{1-(1+i)^{-n}}$

where, A is the amount A=$9999

r is the rate =7.5%=0.075

$i=\frac{r}{12}=\frac{0.075}{12}=0.00625$

time t=4 years

Time in months $n=t\times 12=4\times 12=48$

Substitute all the values in the formula,

$M=\frac{9999\times 0.00625}{1-(1+0.00625)^{-48}}$

$M=\frac{62.49375}{1-(1.00625)^{-48}}$

$M=\frac{62.49375}{1-0.7415101}$

$M=\frac{62.49375}{0.25848}$

$M=241.76$

Therefore, the monthly payment is $241.76.
