Answer:

A, A, A, B, D

Step-by-step explanation:

1.

P(A) = 1/6, P(B) = 1/2

P(A and B) = 1/6*1/2 = 1/12

2.

P(A) = 1/6

P(B) = 1/6

P(A and B) = 1/6*1/6 = 1/36

3.

P(A) = 2/6 = 1/3

P(B) = 1/3

P(A and B) = 1/3*1/3 = 1/9

4.

P(gold) = 4/7 for each

P(2 golds) = 4/7*4/7 = 16/49

5.

Remaining marbles:

2 white, 1 orange and 2 green. Total 5 marbles

P(green) = 2/5

HELP PLZZ I FORGOT HOW TO DO THIS!!!! What is the surface area of the square pyramid represented by the net?



Enter your answer in the box.

Answers

Answer:

39[tex]ft^{2}[/tex]

Step-by-step explanation:

Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height

All four triangles are similar. So finding the area of one triangle, will be the area of the other triangles.

 [tex]\frac{1}{2}[/tex] × 3 × 5 = 7.5[tex]ft^{2}[/tex]

∴ The area of 4 triangles are 7.5 × 4 = 30[tex]ft^{2}[/tex]

Then the only shape remaining is the square.

Area of the square = [tex]length^{2}[/tex] (all the sides of a square are equal)

= [tex]3^{2}[/tex] = 9[tex]ft^{2}[/tex]

Total surface area = 30 + 9 = 39[tex]ft^{2}[/tex]

Robin made ribbons for school spirit day. Robin has 15 friends who
want ribbons. Her roll of ribbon was 30.8 feet long. For each individual
ribbon she needed 0.625 ft. How many ribbons could she make from
her roll?

Answers

Answer:

She can make 97 ribbons from her roll

Step-by-step explanation:

30.8 divided by 0.625 is 97.28, but the friends would like whole rolls, so I got 97

Answer:

Robin can make 49.28 ribbons. Or if you wish to round, 49 ribbons.

Step-by-step explanation:

Her roll of ribbon is 30.8 ft long.

She needs 0.625 ft for each ribbon.

Divide 30.8 by 0.625

30.8 ÷ 0.625 = 49.28

What is the perimeter of the figure on the coordinate plane below?


Answers

Answer:

26 units

Step-by-step explanation:

im not sure if this will help but i counted the spaces and added the halves

The perimeter of the given figure on the coordinate plane is 56 units.

What is perimeter?

A perimeter is the closed path that encompasses surrounds, or outlines either a two dimensional shape or a one-dimensional length.

Now from given figure, the following length of the sides is given,

9 units

4 units

4 units

8 units

11 units

3 units

2 units

15 units

Now since we know that,

Perimeter = Sum of lengths of all the sides

⇒ Perimeter = 9+4+4+8+11+3+2+15

⇒ Perimeter = 56 units

Thus, the perimeter of the given figure on the coordinate plane is 56 units.

The point (5, -1) is reflected over the
x-axis. What are the new coordinates?
A. (-5, 1)
B. (-5, -1)
C. (5, 1)
D. (-1,5)

Answers

Answer:

c

Step-by-step explanation:

when reflected across the x-axis the x becomes  negative and vise versa

when reflected across the y axis the y becomes negative and vise versa  

The new coordinates will be  [tex](5,1)[/tex] .

What are coordinates ?

Coordinates determine the position of the points or other geometric elements on graph.

We have,

Point [tex](5, -1)[/tex].

Reflected over x-axis,

So,

If a point [tex]( x,y)[/tex] under a reflection on the x-axis will be [tex](x,-y)[/tex] .

So,

according to the above mentioned statement,

Point [tex](5, -1)[/tex] reflected on the x-axis

We get ,

Reflected point [tex](5,1)[/tex] .

So, the new coordinates are  [tex](5,1)[/tex] .

Hence, we can say that the new coordinates will be  [tex](5,1)[/tex] .

The circle graph represents a family’s monthly budget. If the total monthly budget is $6,500.00, how much more does the family spend on housing than food?

Answers

Answer:

Use the percentages to help you.

Ask yourself, what is 25% of $6,500.00?

Turn your percent into a decimal which is 0.25

then multiply $6,500 by 0.25

you should get 1625.

Find the amount of money spent on the food and find the difference of the two.

C. $390.00

Explanation:

Housing: 6,500/.25= $1,625
Food: 6,500/.19= $1,235

Subtraction:
$1,625 - $1,235= $390

The family spends $390.00 more dollars in housing than food.
