A gum ball machine has 6 red gum balls, 3 green gum balls, and 5 blue gum balls. What is the probability that the next gum ball that comes out will be red?
Answer:
Step-by-step explanation:
P(red gum ball)= 6/14=3/7
6/14 can be simplified to 3/7 by dividing by 2. 6/2=3. 14/2=7.
P(red gum ball)=3/7

Tell whether the triangle with the given side lengths is a right triangle. 36, 77, 85, true or false
Answer:
True the triangle is a right triangle.
Step-by-step explanation:
the Pythagorean Theorem states that [tex]a^{2} +b^{2} =c^{2}[/tex]
so,
[tex]85^{2} =7225\\77^{2} =5929\\36^{2} =1296\\5929+1296=7225[/tex]
1. Find the value of x to the nearest tenth
A. 19.2
B. 20.8
C. 21.3
D. 19.7
Answer:
20.8
Step-by-step explanation:
Use the Pythagoras's Theorem
12²-36²=[tex]\frac{x}{2}[/tex]²
144-36=[tex]\frac{x}{2}[/tex]²
108=[tex]\frac{x}{2}[/tex]²
Root both sides
√108=√[tex]\frac{x}{2}[/tex]²
[tex]\frac{x}{2}[/tex]≈10.4
[tex]\frac{x}{2}[/tex]·2=10.4·2
x=20.8
The length of a box is 6 inches, the width is 4 inches and the height is 2/8 inches. What is the volume of the box?
Answer:
6 cubic inches
Step-by-step explanation:
To find the volume of a box you do Length * Width * Height
So we can do:
6*4*2/8
=24*2/8
=6
The volume of the box is 6 cubic inches

I don't know Spanish/what laugnange you speak sorry.
what is b
−2.9+ b/0.1 = − 39.9
Answer:
b = - 1.09
Step-by-step explanation:
- 2.9 + b ÷ 0.1 = - 39.9
- 2.9 + b ÷ 0.1 × 0.1 = - 39.9 × 0.1
- 2.9 + b = - 3.99
- 2.9 + 2.9 + b = - 3.99 + 2.9
b = - 1.09
Answer:
Exact form
b=-37/10
Decimal form
b=-3.7
Mixed Number form
b+-3 7/10
Step-by-step explanation:
-2.9+b/1/10+-39.9
-2.9+10b+-39.9
10b=-39.9+2.9
10b=-37
b=-37/10

hi, i know this is basic math and stuff but I still need some help
Answer:
the answer is :
20 for the first figure
12 for the second figure
30 for the last figure
Answers:
Perimeter = 22 cmPerimeter = 22 cmPerimeter = 30 cm==============================================
Explanation:
The perimeter is the total distance around the outer edge of the figure. It's the total amount of fence you need to enclose the region.
So we simply add up all the side lengths. Refer to the diagram to see any missing sides that aren't labeled (shown in blue).
For instance, the perimeter for problem 1 is 5+2+2.5+4+2.5+6 = 22 cm. Problems 2 and 3 are handled the same way.
It's not a typo that the perimeters of problems 1 and 2 are the same value. This is because both figures can be surrounded by a rectangle that is 6 cm across and 5 cm tall. The perimeter of the surrounding rectangle is exactly the same as the perimeter of the inner fenced region. We're effectively just moving fence around but not changing the perimeter.

Which input value produces the same output value for the two functions on the graph
X = 1
Because where the two lines intersect, they have the same x value, one
Answer:
x = 1
Step-by-step explanation:
Look at the graph to see where the lines intersect.
f(1) = 1
g(1) = 1
When x = 1, the output value of both functions is 1.
Answer: x = 1

Step-by-step explanation:
Jacqui likes to travel to the beach on weekends. She starts at her house, drives d miles, and then spends t hours walking the remaining w miles to get to the beach. Jacqui drives three times as long as she walks during the trip. The equation below represents Jacqui's average speed, a, in miles per hour, when traveling to the beach. a=d+w/3t+t What is the meaning of 3t + t3t+t in the equation above? -The total time that Jacqui spends traveling to the beach -The time that Jacqui spends driving to the beach -The total distance that Jacqui travels to the beach -Jacqui's maximum speed during her trip Jacqui's average speed during one trip to the beach was 3636 miles per hour. If Jacqui drove 70 miles and the entire trip to the beach took her 22 hours, how many miles did she walk to get to the beach?
Answer:
The answer is below
Step-by-step explanation:
1) Average speed is the ratio of the total distance travelled to the total time taken. Hence it is given by:
Average speed = total distance / total time
Total distance = d miles + w miles
Jacqui drives three times as long as she walks during the trip, hence:
time spent driving = 3t
Total time = 3t + t
Average speed = total distance / total time
a = (d + w) / (3t + t)
2) (3t + t) represents the total time that Jacqui spends traveling to the beach.
3) Given that a = 36 miles per hour, total time = 2 hours
a = total distance / total time
36 miles per hour = total distance / 2 hours
total distance = 72 miles
Total distance = distance walk + distance drove
72 = distance walk + 70
Distance walk = 2 miles

in a group of 120 students,90 students study mathematics and 72 study science. if 10 of the student does not study any subject
1)find the no.of students who study atleast 1 subject
2)number of students studying both subjects
3)how many students will study mathematics only?
4)how many students will study science only?
Answer:
Step-by-step explanation:
Total students = 120
Number of students studying Mathematics P(A) = 90
Number of students studying Science P(B) = 72
Number of students who doesn't study both subjects P(AUB)'= 10
1) Number of students studying atleast on subject = 120 -10 = 110
2) Number of students studying both math and science = (90 +72) -110
= 162 -110 = 52
3) Number of students studying only mathematics = 90 -52 = 38
4) Number of students studying only science = 72 -52 = 20

Ron invested $700 for 9 years at 3.4% compounded semi-annually. How many compounding periods are there over the term of the investment?
Answer:
financial equations use the formula
[tex]A=P (1 + \frac{r}n)} ^{nt}[/tex]
where
A is accrued amount
P = principal
r= interest rate
t = number of periods (NOTE: NOT NUMBER OF YEARS !!!)
r = interest rate (NOTE: APR the whole years interest NOT the period)
So in your question the compounding is being done "Semi-annually:
NOTE:
Annual = 1
semi-annual = 2
Quarterly = 4
monthly = 12
So your number of periods is ..... number of years (9) times the number of periods in a year (2 - for semi-annual)
9 * 2 = 18 there are 18 periods
[tex]A=P (1 + \frac{.034}2)} ^{18}[/tex]

Dada a função fx=0,15.X+900 , determine a) f(80) b) f(120) c) f(200) d) f(56)
Answer:
See answers below
Step-by-step explanation:
Given the function:
f(x) = 0.15x + 900
a) f(80) = 0.15(80) + 900
f(80) = 12 + 900
f(80) = 912
b) f(120) = 0.15(120) + 900
f(120) = 18 + 900
f(120) = 918
c) f(200) = 0.15(200) + 900
f(200) = 30 + 900
f(200) = 930
d) f(56) = 0.15(56) + 900
f(56) = 8.4 + 900
f(56) = 908.4
5. The property depicted in the expression 2/( 3) ×(1/3+ 4/5)=(2/3 × 1/3)+(2/3 × 4/5) is *
associative property of addition
associative property of multiplication
distributive property of multiplication
closure property of multiplication
Answer:
distributive property of multiplication over addition
Step-by-step explanation:
a(b + c) = ab + ac
The a to the left of the parentheses multiplies both numbers inside the parentheses. The you add the products.
This is the distributive property of multiplication over addition.
2/3 × (1/3 + 4/5) = (2/3 × 1/3) + (2/3 × 4/5)
The 2/3 to the left of the parentheses multiplies both numbers inside the parentheses. The you add the products.
This is the distributive property of multiplication over addition.
