A bag contains. 7 red, 8 blue, 2 green, 5 black, and 3 yellow marbles. A marbles will be drawn from the bag and replaced 175 times. what is the reasonable prediction for the number of times a yellow or green marble be drawn?
A. 35
B. 25
C. 5
D. 7
Answer:
A. 35
Step-by-step explanation:
The total number of marbles is 25
The number of green & yellow marble is 5
The probability of getting a yellow or green marble (if drawn once) = 5/25
So, if drawn 175 times, 5×175/25 = 35
Ashleys Shoe Store buys shoes for $35 and then sells them for
$85.
What is the percent of increase on the price of the shoes?
Round to the nearest whole number
Step-by-step explanation:
% Increase = ((New value - Old Value) / Old Value) * 100
Given New value = $85
and Old Value = $35
% Increase =
[tex] (\frac{85 - 35}{35} ) \times 100 \\ = ( \frac{50}{35} ) \times 100 \\ = 143percent(nearest \: whole \: number)[/tex]
explain how to isolate the variable in the equation -2/3+7=15
Answer:
n= -12
Step-by-step explanation:
- 2n/3 + 7=15 Subtract 7 from both sides and move all terms containing
-7 = -7 n to the right
- 2n/3 = 8 multiply both sides of equation by - 3/2
-3/2 x (-2n/3) = -3/2 x 8
n= -3/2 x 8 cancel the common factor of 3
n= -12
how to solve 7x+(-3)=18
Answer:
x=3
Step-by-step explanation:
7x(-3)=18
add 3 to both sides
7x=21
divide by 7 on both sides
x=3
Answer:
7x+(-3)=18
7x-3=18
7x-3+3=18+3
7x=18+3
7x=21
7x/7=21/7
x=21/7
x=3

Answer:
A. 117.2 cubic feet
Step-by-step explanation:
Volume of the cone = ⅓πr²h
Where,
r = 4 ft
h = 7 ft
π = 3.14
Substitute
Volume = ⅓*3.14*4²*7
Volume = 117.226667 ≈ 117.2 cubic feet

Costas has an after school job. He budgets his money, allowing 0.31 of his earnings for food and 0.58 of his earnings for entertainment. The rest of the money he saves. If he earns $67.50 per week, which is the best estimate of the amount of money he saves each week ?
Answer: the amount of money he saves a week is $19.56
Step-by-step explanation: I am assuming that you mean percent so you subtract the percentages ($67.50 - 58%) - 31% This should give you a remaining amount of $19.56

Find the base of a parallelogram with a hight of 10.5 feet and an area of 189 square feet?
Base=18
Step-by-step explanation:
I have used area equals to base times height that's the formula of a parallelogram and I've gotten that base equals to 18 hope this helps.
Need help asap !!!! It also said round to the nearest tenth
Answer:
4524.9
Step-by-step explanation:
Area of a parallelogram:
A = bh
A = 63 x 90
A = 5670
Area of half-circle:
A = (πr²)/2
A = (π x 27²)/2
A = (π x 729)/2
A = 729/2π
Combined:
5670 - 729/2π
4524.9

Prove: The opposite sides of a parallelogram are equal.
Answer:
A=(0,0), B=(b,0), C=(b+c,d), D=(c,d) Then Using the distance formula
DC=√(c-[b+c])2+(d-d)2 DC=√b2 DC=b AB=√(0-b)2+(0-0)2 AB=√(-b)2 AB=√b2 AB=b then DC=AB DA=√(c-0)2+(d-0)2 DA=√c2+d2 CB=√(b+c-b)2+(d-0)2 CB=√c2+d2 then DA=CB

find the perimeter of the figure
Answer:
(19x+10)/2
Step-by-step explanation:
Perimeter of the figure is the sum of all the sides
Perimeter of the figure = 4x+3 + x+2+2x+2 + x/10 -1 + 2x/5 + 2x-1
Perimeter of the figure = 4x+x+2x+2x+x/10+2x/5 + 3 + 2 + 2 -1-1
Perimeter of the figure = 9x + (x+4x)/10 + 5
Perimeter of the figure = 9x + 5x/10 + 5
Perimeter of the figure = 9x + x/2 + 5
Perimeter of the figure = (18x+x)/2 + 5
Perimeter of the figure = 19x/2 + 5
Perimeter of the figure = (19x+10)/2

PLEASE HELP ME FIND THE DISTANCE OF THE DIAGONAL
Step-by-step explanation:
Let x be the diagonal distance,
by pythagoras' theorem,
[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]
where c is the diagonal
a and b are the 2nd and 3rd longest side, interchangeable.
given a = 50m, b = 25m,
[tex] {c}^{2} = {50}^{2} + {25}^{2} \\ {c}^{2} = 2500 + 625 \\ {c}^{2} = 3125 \\ c = \sqrt{3125} \\ = 55.9m \: (nearest \: tenth)[/tex]
