What Percentage Of This Grid Is Shaded?b)How Many More Squares Need To Be Shadedso That 80% Of The Grid

Answers

Answer 1

Answer:

52% of the grid is shaded. You would need 7 more squares in order to get 80%.

Step-by-step explanation:

There are 25 boxes. You want to figure out how much each box is worth.

So,

You divide 100 by 25. You will get an answer of 4.

So now you know how much each box is worth.

There are 13 boxes shaded in, so you multiply 13 by 4 to get 52.

Keep adding boxes in order to get 80%. For example, 52%, 56%, 60%, until you get to 80%. Then see how many boxes you added up to get 80%.

Answer 2

We would need 7 more squares in order to get 80%. Thus, 52% of the grid is shaded.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

There are 25 boxes. we want to figure out how much each box is worth.

So,

100 / 25 = 4

Now, we know how much each box is worth.

There are 13 boxes shaded in,

so 13 x 4 = 52.

Keep adding boxes in order to get 80%.

For example, 52%, 56%, 60%.

The library has 65400 art books and 9600 science books. What part of all the books are science books

Answers

Answer:

9,600/75,000, 16/125

Step-by-step explanation:

art+science=75000

9600

75000    =16/125

The part of all the books that are science books is 0.128 or 16/125.

Using this formula

Science books=Science books(Art books+Science books)

Where:

Science books=9600

Art books=65400

Let plug in the formula

Science books=9600/(65400+9600)

Science books=9600/75000

Science books=0.128 or 16/125

Inconclusion the part of all the books that are science books is 0.128 or 16/125.

A number cube is rolled 360 times and the results are recorded as follows: 52 ones, 59 twos, 67 threes, 73 fours, 42 fives, and 67 sixes. What is the experimental probability of rolling a two or a three?

Answers

Answer:

0.35

Step-by-step explanation:

Total rolled = 360 times

Two rolled = 59

Three rolled = 67

Two rolled probability = 59/360 = 0.164

Three rolled probability = 67/360 = 0.186

The experimental probability of rolling a two or a three

==> Two rolled probability + Three rolled probability

==> 0.164 + 0.186

==> 0.35

Answers

Answer:

Answer: A) -8

Step-by-step explanation:

The image shows the triangle where it can be noted that two of its sides are congruent (according to the tick marks). This forms an isosceles triangle that also has two congruent angles as shown in the image below.

The other angle (2) has a measure of x+88.

The sum of the internal angles of the triangle must be 180°, thus:

x + 88 + 50 + 50 = 180

Simplifying:

x + 188 = 180

x = 180 - 188 = -8

x = -8

Answer: A) -8

A baker made 9 cupcakes, each a different type. Four people want to share them equally. How many cupcakes will each person get? DIvide and use in fraction form.

Answers

Answer: 2 1/4

Step-by-step explanation:

From the question, we are informed that a baker made 9 cupcakes which are to be shared equally by four people.

To get the number of cupcakes that each person gets, we divide the total number of cupcakes by the total number of people. This would be:

= 9 ÷ 4

= 2 1/4 cupcakes

Therefore, each person gets 2 1/4 cupcakes.

Raphael purchases a new DVD at M-Mart. He
pays 8% in tax on the cost of the DVD. If the tax
amount is $1.20, how much does Raphael
spend on the DVD, including tax?

Answers

Answer:

The amount Raphael spend on DVD including tax is $16.2

Step-by-step explanation:

Tax on DVD = 8%

Amount of tax = $1.20

We need to find the amount Raphael spend on DVD including tax.

Let the cost of DVD = x

We can write the equation: [tex]8\%\:of\:x=1.20[/tex]

Because the tax amount is 8% of actual cost and is equal to 1.20

Now solving to find x:

[tex]8\%\:of\:x=1.20\\8\%\times\:x=1.20\\\frac{8}{100}\times x=1.20 \\x=1.20 \times \frac{100}{8}\\x= 15[/tex]

So, the cost of DVD = $15

Now, The amount Raphael spend on DVD including tax = Cost of DVD + Tax

The amount Raphael spend on DVD including tax = 15 + 1.2

                                                                                    = 16.2

So, The amount Raphael spend on DVD including tax is $16.2
