I need to find the area of my shape

k0ka [10]

Answer:

Formula for area of triangle:

A = bh x 1/2

Formula for area of parallelogram:

A = bh

Now find the area of the figure above which is a triangle:

3(base) x 8(height) x 1/2 = 12

Let's find the area of the parallelogram;

6(height) x 9(base) = 54

Add the two areas together:

12 + 54 = 66 cm2

Suppose a basket of goods and services has been selected to calculate the cpi and 2014 has been selected as the base year. in 20

KATRIN_1 [288]

Consumer Price Index or also most commonly known as CPI is calculated through the equation,
CPI = (price at a certain year / price at base year) x 100
Since, we have chosen 2014 as the base year, the denominator of the fraction will be $86. Calculating the CPI for 2015,
CPI = ($90/$86) x 100
= 104.65

I’m thinking of a number. When you multiply it by 3 and subtract 10 you will get a number less than 5. Form an inequality and so

sweet-ann [11.9K]

Answer:

$3x-10$

Step-by-step explanation:

Let x be equal to the number.

We can use what the question gives us to directly form a mathematical statement. When you multiply it by 3 (3x) and then subtract 10 (3x-10) you will get a number less than 5 (<5). Using this, our mathematical statement would look like this:

$3x-10$

To find the range of possible values, we must solve the inequality and isolate x.

$3x-10$

Add 10 to both sides

$3x-10+10$

Divide both sides by 3

$\frac{3x}{3}$

I hope this helps!

How do you convert a mixed fraction to an improper fraction ?

maks197457 [2]

Answer:

see the explanation

Step-by-step explanation:

we know that

A mixed number is equal to sum a integer plus a fraction less than 1. The result is a fraction where the numerator will be always greater than the denominator (This fraction is called an improper fraction)

Example

$a\frac{b}{c}$ ----> a mixed number

a is a integer

b/c < 1

$a\frac{b}{c}=a+\frac{b}{c}$

Adds the integer plus the fraction

$\frac{ac+b}{c}$ ---> an improper fraction

$\frac{ac+b}{c} > 1$
