Answer:
[tex]\frac{10}{49}[/tex]
Step-by-step explanation:
There are 23 red candies, 16 blue candies and 10 yellow candies.
Which means altogether we have..
23 + 16 + 10= 49
49 candies.
To find the probability of picking a yellow piece, we know that there are 10 yellow candies out of 49 candies.
So the chances of getting a yellow piece is [tex]\frac{10}{49}[/tex]
10 YELLOW CANDIES
49 CANDIES

Answer:
7/3
Step-by-step explanation:
5 - 3(2a+1) = -4 + 10
=> 5 - 6a + 3 = 6
=> 5 - 6 + 3 = 6a
=> 2 = 6a
=> 6a = 2
=> a = 2/6
=> a = 1/3
a + 2
1/3 + 2
=> 1/3 + 6/3
=> 7/3

The trick is to let the letters = points of a clock that keeps time this way.
l = 9 oclock
C = 3 oclock
-H= -8
Formula
(x - l) / C = -H
Solution
Substitute the givens into the equation
(x - 9) / 3 = -8 Multiply both sides of the equation by 3
3*(x - 9)/3 = -8*3 Simplify
(x - 9) = - 24 Remove the brackets
x - 9 = - 24 Add 9 to both sides.
x-9+9 = -24+9 Combine
x = - 15

If a gas tank can hold 30 gallons, how many gallons does it contain when it is three-fifths full?
Answer:
3/5 of 30 = (3/5)*30
3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/5
3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/5
3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18
3/5 of 30 = (3/5)*303/5 of 30 = (3*30)/53/5 of 30 = 90/53/5 of 30 = 18So when the tank is 3/5 full, there are 18 gallons in the tank.

Bradley $15 painting a fence for two hours and 30 dollars for pressure washing the patio and deck for 4 hours. Did he learn the same amount per hour for. Both jobs? Explain
Yes, he earns the same amount per hour for the fence because in two hours he earned 15. The pressure washing and deck was 4 hours and every 2 hours he got 15.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that, Bradley $15 for painting a fence for two hours and 30 dollars for pressure washing the patio and deck for 4 hours.
Bradley $15 painting a fence for two hours, its unit rate is
=$15 / 2 hours
=$ 7.5 per hour
If 30 dollars for pressure washing the patio and deck for 4 hours, the unit rate is
=$ 30 /4 hours
=$ 7.5 / hour
Thus, he earns the same amount per hour for the fence because in two hours he earned 15. The pressure washing and deck was 4 hours and every 2 hours he got 15.

A pool charges $7 for 2 daily pool passes.
Which table could represent the situation?
Answer:
Therefore, membership of the pool will be less expensive until number of visits to the pool is one fourth of the membership.
Option B is the table which could represent the given situation.
What is a linear equation?A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.
According to the question
A pool charges $7 for 2 daily pool passes.
Using the linear equation y = mx + b
Substitute x = 2, y = 7
[tex]7 = 2m + b[/tex].....(1)
Substitute x = 4, y = 14
[tex]14 = 4m + b[/tex] .....(2)
Using elimination method
Subtract equation 1 from 2
[tex]14 - 7 = 4m - 2m + b - b[/tex]
[tex]7 = 2m[/tex]
[tex]m=\frac{7}{2}[/tex]
Substitute m = [tex]\frac{7}{2}[/tex] in equation 1
[tex]7=2(\frac{7}{2} )+b[/tex]
b = 7 - 7
b = 0
Substitute b = 0 in equation 1
7 = 2m
Similarly
14 = 4m
21 = 6m
28 = 8m
Hence, Option B is the table which could represent the given situation.

Amy uses 48-cent stamps and 7-cent stamps to mail a gift card to a friend. If the postage is $2.07, how many of each stamp did Amy use?
9514 1404 393
Answer:
3 48-cent stamps
9 7-cent stamps
Step-by-step explanation:
The number of 48-cent stamps Amy can use is less than 207/48 ≈ 4.3, so we can find the numbers by trial and error. We want ...
48a +7b = 207 . . . . . . postage in cents, where a, b are the numbers of stamps
b = (207 -48a)/7 = 29 4/7 -a(7 -1/7) = (29 -7a) +(a+4)/7
In order for b to be an integer, we must have (a+4) a multiple of 7. The least value of 'a' that will make this true is a=3. That value gives ...
b = (29 -7·3) +(3+4)/7 = 8 +1 = 9
Amy used 3 48-cent stamps and 9 7-cent stamps.

Express the edge length of a cube as a function of the cube's diagonal length d. Then express the surface area and volume of the cube as a function of the diagonal length.
a. A function for the edge length of a cube is L(d) = _________________
b. A function for the surface area of a cube is Ald) = _____________
c. A function for the volume of a cube is V(d) = ________________
Answer:
Step-by-step explanation:
If L is the length of a side, the longest diagonal in the cube is
d = √(L² + L² + L²) = √(3L²) = L√3
meaning
a) L(d) = d/√3 = ⅓d√3
b) A(d) = 6(L(d))² = 6(⅓d√3)² = 6(⅟₉d²(3)) = 2d²
c) V(d) = (L(d))³ = (⅓d√3)³ = ⅟₂₇d³3√3 = ⅟₉d³√3
