Split the figure into 4 triangles

Area 1 triangle = 1/2 x base x height
Area 1 triangle = 1/2 x 7.5 x 6
Area 1 triangle = 22.5 in²

Area of 4 triangles = 22.5 x 4
Area of 4 triangles = 90 in²

Answer: 90 in²

There are 10 sweets in a bag.

Valentin [98]

Answer:

See Explanation Below

Step-by-step explanation:

Given

Total Sweets = 10

Red = 4

Green = 2

Yellow = 3

Purple = 1

Required

a & b

The question is not properly presented; however the solution is as follows;

Let P(Yellow) represent the probability of selecting a yellow sweet and n(Yellow) represent the number of Yellow sweets;

$P(Yellow) = \frac{n(Yellow)}{Total}$

$P(Yellow) = \frac{4}{10}$

$P(Yellow) = 0.4$

So, whichever letter that shows $0.4$ or $\frac{4}{10}$ is the probability of choosing a yellow sweet

Let P(Orange) represent the probability of selecting an orange sweet and n(Orange) represent the number of orange sweets;

Since, there's no orange sweet in the bag;

$n(Orange) = 0$

$P(Orange) = \frac{n(Orange)}{Total}$

$P(Orange) = \frac{0}{10}$

$P(Orange) = 0$

In probability; opposite probabilities add up to 1;

Let P(Not\ Orange) represent the probability of choosing a sweet that is not orange

$P(Not\ Orange) + P(Orange) = 1$

Substitute $P(Orange) = 0$

$P(Not\ Orange) + 0 = 1$

$P(Not\ Orange) = 1$

So, whichever letter that shows 0 is the probability of choosing a sweet that is not orange

Torri had $20 to buy a birthday present for her dad. She decided to buy a DVD for $18. The sales tax is 7 percent. Does she have

vesna_86 [32]

First, we need to calculate the cost of the sale tax. To do it, we are going to convert the sale tax from percentage to fraction by dividing it by 100, and then we are going to multiply the cost of the DVD by the sale tax:

$Sale.Tax=\frac{7}{100}$

Now, we can multiply the cost of the DVD by the sale tax to find the cost of the sale tax:

$Cost.Sale.Tax=18(\frac{7}{100)} )=9(\frac{7}{50} )=\frac{63}{50} =1.26$

Now that we know that the sale tax is $1.26, we are going to add the cost of the sale tax to the cost of the DVD and check if that sum is less or equal than Torri's money (20$):

$Total.Cost=18+1.26=19.26$

Since $19.26 $\leq$ $20, we can conclude that Torri has enough money to buy the DVD. In fact, Torri will end with a change of $0.74 after buying the DVD.
