Alexis is drawing jolly ranchers from two bags the fist bag has 4 red 2 green and one blue the second bag has 4 red and 2 orange what is the probability that he would choose a purple jolly rancher from the first bag and a red jolly rancher from the second
Answer and explanation:
The two events of choosing jolly ranchers from each bag, first and second are independent events so the probability of first event AND second event will be multiplied
First bag has 4 red 2 green and one blue
Second bag has 4 red and 2 orange
what is the probability that he would choose a purple jolly rancher from the first bag and a red jolly rancher from the second
Probability = number of favourable outcomes /total number of favourable outcomes
The first bag does not have a purple jolly rancher and so probability is zero
the second bag's probability of choosing a red jolly rancher =4/6
probability of choosing a purple jolly rancher from first bag and red jolly rancher from second bag
=0*4/6=0

Step-by-step explanation:
A car dealership paid $9,000 for a car. The sticker price is $10,395 for a customer to buy the car. a. What’s the markup in dollars? b. By what percent is the markup?
Answer:
1) To determine how much the change of $9,000 to $10,395, we must subtract 9,000 from 10,395;
10,395 - 9,000 = $1,395 is the change in price (an increase).
Formula to find percentage of change;
Change in price/original amount x 100% (100/100)
Replace those values:
1,935 (change in price/increase) 100
_____ x _____ = %0.215
9,000(original amount) 100
Find the area of a square with sides of length 1/3 yard. please help fast!
A. 1/3 sq yd
B. 14 sq yd
C. 1/9 sq yd
D. 2/9 sq yd
Answer:
The answer is 1/9 square yard. I hope this helps!
Answer: C. 1/9 sq yd
Step-by-step explanation:
To find the area of a square, you do the side length squared. (1/3)^2 is the same as (1/3) * (1/3). Multiply the numerators together to get 1 * 1 = 1 and the denominators to get 3 * 3 = 9. This gives you 1/9.
This isosceles triangle has two sides of equal length, a, that are longer than the length of the base, b. The perimeter of the triangle is 15.7 centimeters. The equation 2a + b = 15.7 models this information. If one of the longer sides is 6.3 centimeters, which equation can be used to find the length of the base?

A high school choir had a car wash to raise money. The number of trucks washed was 2 fewer than half the total number of cars and SUVs washed. They washed twice as many cars as trucks. They washed a total of 28 trucks and cars and SUVs. Let T = the number of trucks, C = the number of cars, and S = the number of SUVs washed. Which ordered triple, (T, C, S) represents the solution to the system below? Verify your answer fully in the box provided.
Answer:
Number of trucks = 28
Number of cars = 14
Number of SUVs = 46
Total number of vehicles = 88
Step-by-step explanation:
Let T = the number of trucks, C = the number of cars, and S = the number of SUVs washed.
We are told :
They washed twice as many cars as trucks.
Hence: T = 2C
They washed a total of 28 trucks and cars and SUVs
Number of trucks = 28
Number of Cars =
T= 2 C
C = T/2
C = 28/2
C = 14
The number of trucks washed was 2 fewer than half the total number of cars and SUVs washed.
T = 1/2(C + S) - 2
T = 28
C = 14
Hence:
28 = 1/2(14 + S) - 2
28 = 1/2(14) + 1/2(S) - 2
28 = 7 - 2 +S/2
28 - 7 + 2 = S/2
30 - 7 = S/2
23 = S/2
S = 23 × 2
S = 46
Hence, number of SUVs = 46
Total number of vehicles = 28 + 14 + 46
= 88

Suppose y varies directly as x, and y = 10 when x = 25. Find y when x = 18.
Answer:
y = 7.2
Step-by-step explanation:
Given that y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 10 when x = 25, then
10 = 25k ( divide both sides by 25 )
[tex]\frac{10}{25}[/tex] = 0.4 = k
y = 0.4x ← equation of variation
When x = 18, then
y = 0.4 × 18 = 7.2
The prism shown has a volume of 35cm³
Work out h, the height of the triangular cross section.
Answer:
h = 2.5 cm
Step-by-step explanation:
the volume (V) of a prism is calculated as
V = Al ( A is the area of triangular base and l the length )
A = [tex]\frac{1}{2}[/tex] bh = [tex]\frac{1}{2}[/tex] × 4 × h = 2h and l = 7
given V = 35 , then
2h × 7 = 35
14h = 35 ( divide both sides by 14 )
h = 2.5 cm

Trina is saving to buy a new phone. She has two options. The first option is to put $400 away initially and save $20 every month. The second option is to put $100 away initially and save $40 every month. After how many months, m, would Trina save the same amount using either option? How much would she save with either option? Write and solve an equation to show your work.
Total amount saved in 1st case :
[tex]S_1=400+20t_1[/tex]
Total amount saved in 2nd case :
[tex]S_2=100+40t_2[/tex]
( Here [tex]t_1 \ and\ t_2[/tex] are number of months )
Let, after x months the amount saved in both cases is same.
So,
[tex]S_2=S_1\\\\100+40x=400+20x\\\\20x = 300\\\\x = 15\ months[/tex]
Amount saved :
[tex]S_1=400+20(15) =\$ 700[/tex]

Dilate the figure below with a scale factor of 1.5 centered at the origin and then rotate the figure 90° clockwise about the origin.
Answer:
Step-by-step explanation:
Vertices of the quadrilateral are (-4, 1), (-3, 2), (-1, 2) and (-2, 1).
If the given quadrilateral is dilated by ta scale factor of 1.5 about the origin.
Rule for the dilation,
(x, y) → (kx, ky) [k = scale factor]
New vertices of the quadrilateral after the transformation will be,
(-4, 1) → (1.5×4, 1.5×1)
→ (-6, 1.5)
(-3, 2) → (-4.5, 3)
(-1, 2) → (-1.5, 3)
(-2, 1) → (-3, 1.5)
Now the new points are rotated by 90° clockwise about the origin,
Rule for the rotation of the points,
(x, y) → (y, -x)
So the new vertices will be,
(-6, 1.5) → (1.5, 6)
(-4.5, 3) → (3, 4.5)
(-1.5, 3) → (3, 1.5)
(-3, 1.5) → (1.5, 3)
We can plot these points on the graph to form a new (image) quadrilateral.
Use the long division method to find the result when 6x^2 + 26x^2 + 23x + 5 is divided by 3x + 1. explain all steps
Dividing 6x^2 + 26x^2 + 23x + 5 by 3x + 1 using the long division involves the use of groups or parts
The result when 6x^2 + 26x^2 + 23x + 5 is divided by 3x + 1 is 2x^2 + 8x + 5 with no remainder
How to carry out the long division?The dividend is given as:
6x^2 + 26x^2 + 23x + 5
And the divisor is 3x + 1
Step 1:Divide 6x^3 by 3x:
Result = 2x^2
Multiply 2x^2 by 3x + 1
=> 6x^3 + 2x^2
Subtract 6x^3 + 2x^2 from 6x^3 + 26x^2 + 23x + 5
=> 24x^2 + 23x + 5
Step 2:Divide 24x^2 by 3x:
Result = 8x
Multiply 8x by 3x + 1
=> 24x^2 + 8x
Subtract 24x^2 + 8x from 24x^2 + 23x + 5
=> 15x + 5
Step 3:Divide 15x by 3x:
Result = 5
Multiply 5 by 3x + 1
=> 15x + 5
Subtract 15x + 5 from 15x + 5
=> 0
Write out the sum of the results
Result = 2x^2 + 8x + 5
Hence, the result when 6x^2 + 26x^2 + 23x + 5 is divided by 3x + 1 is 2x^2 + 8x + 5 with no remainder

Sarah hit the ball 3 times out of the 8 times. What is the experimental probability (as a percent) that she will hit the ball next? A 22.5% B 37.5% 45% 3% asap
Answer:
B
Step-by-step explanation:
3/8 is equal to 0.375, also known as 37.5%.
The experimental probability (as a percent) that she will hit the ball next is 37.5%. Hence, option B is the right choice.
What do we mean by the experimental probability of an event?The experimental probability of an event occurring is the number of times it happened during the experiment as a ratio to the number of times the experiment was run.
How do we solve the given question?In the question, we are given that Sarah hit the ball 3 times out of the 8 times.
We are asked to find the experimental probability (as a percent) that she will hit the ball next.
As we know, the experimental probability of an event occurring is the number of times it happened during the experiment as a ratio to the number of times the experiment was run.
∴ The experimental probability = The number of times Sarah hit the ball/The number of times she experimented = 3/8
or, The experimental probability = (3/8)*100 % = (3*25)/2 % = 75/2 % = 37.5%.
∴ The experimental probability (as a percent) that she will hit the ball next is 37.5%. Hence, option B is the right choice.
