What is the probability of choosing a red chip from a bag containing 3 red, 2 blue, and 5 yellow chips?

Answer:

solution given:

Area of triangle ABC=½b×h=½×18×21=189km²

Area of square DEFG=l²=9²=81km²

Area of rectangle DHIJ=l×b=4×13=52km²

Total area =189+81+52=322 square kilometers.

Answer:

[tex] \rm\displaystyle A _{ \text{total}} = 322 {km}^{2} [/tex]

Step-by-step explanation:

refer the attachment

we have a triangle,a rectangle and a square

in order to figure out the area of the total figure we need to figure out the area the attached figure first

the triangle has a base of 18 km and a height of 13+6+2=21km

thus,

the area of the triangle is

[tex] \displaystyle \frac{1}{2} \times 18 km\times 21km[/tex]

reduce fraction:

[tex] \displaystyle 9 km\times 21km[/tex]

simplify multiplication:

[tex] \displaystyle 189 km ^{2} [/tex]

the rectangle has a length of 13km and a width of 4km

thus,

the area of the rectangle is

[tex] \displaystyle 13km \times 4km[/tex]

simplify multiplication:

[tex] \displaystyle {52km}^{2} [/tex]

the length of every sides of the square is 9km

thus,

the area of the square is

[tex] \displaystyle {(9km)}^{2} [/tex]

simplify square:

[tex] \displaystyle {81km}^{2} [/tex]

[tex] \rm\displaystyle A _{ \text{total}} = A_{ \text{triangle}} + A_{ \text{rectangle}} + A_{ \text{square}}[/tex]

substitute:

[tex] \rm\displaystyle A _{ \text{total}} = 189 {km}^{2} + 52 {km}^{2} + 81 {km}^{2} [/tex]

simplify addition:

[tex] \rm\displaystyle A _{ \text{total}} = 322 {km}^{2} [/tex]

The required expression for the given property is 8(9 + 3).

The distributive property for the product of a sum of numbers to other numbers states that it is equivalent to the sum of individual products. It can be written as a(b + c) = ab + ac.

The given expression is 72 + 24

In distributive form it can be written as,

GCF of 72 and 24 is 8.

Then, 72 = 8 × 9 and 24 = 8 × 3

Now, the given expression can be rewritten as below,

8 × 9 + 8 × 3

Take 8 as common to get,

8(9 + 3)

Hence, the expression that represents the distributive property is 8(9 + 3).

Answer:

d. How many animals weigh at least 15 pounds?

Step-by-step explanation:

The histogram displayed holds information about the number of animals who have a certain certain weight interval. Hence, answering questions about a point weight such as the number of animals whose weight is 4.9. This is a point value and such information given by the histogram.

Similarly, number of animals for intervals which aren't Cleary and explicly stated on the horizontal x - axis of the histogram cannot be determined by the histogram such as ; number of animals weighing less than 8 pounds and number of animals weighing between 5 and 10 pounds.

However, the number of animals weight less Than 15 pounds can be obtained from the histogram. This includes the sum give by the first, second and third bar. This is about (8 + 17 + 10) = 35 animals.

Answer:

x = 25.

Step-by-step explanation:

Original cost per person:: 2000/x

Changed cost per person:: 2000/(x-5)

---------------------------

Equation:: changed - original = 20

2000/(x-5) - 2000/x = 20

2000x - 2000x + 2000*5 = 20x(x-5)

10000 = 20x^2-100

----

500 = x^2 - 5x

------------------

x^2 - 5x - 500 = 0

(x+20)*(x-25) = 0

-----

Only positive root makes sense ====> x = 25.

A. 0.15c B. 0.85c C. 1.15c D. 1.85c

Given:

c + 0.85c

c standing alone has a coefficients of 1

The coefficients of 0.85c is 0.85

The two terms have the same variable c

Add both terms together

Given

[tex]Allen = \frac{3}{4}hr[/tex] less than the most hour

Required

Hours read by Miss Allen

The question is incomplete, as the hours read by each student is not given.

To solve this, I will assume that the longest hours read by a student is x.

So, the expression for Miss Allen will be:

[tex]Allen = x - \frac{3}{4}hr[/tex]

Assume that [tex]x = 1hr[/tex]

The expression becomes

[tex]Allen = 1hr - \frac{3}{4}hr[/tex]

Take LCM and solve

[tex]Allen =\frac{4 - 3}{4}hr[/tex]

[tex]Allen =\frac{1}{4}hr[/tex]
