A teacher has 104 pieces of candy if there are 13 students in the candies divided evenly how many pieces will each student get
Every student will get 8 candies.
What is division?Division is a process of splitting a specific amount into equal parts.
Given that, A teacher has 104 pieces of candy, which she equally divides to her 13 students.
Therefore, for calculating how many candies each of them is getting, we will divide total number of candies to the total number of students,
Therefore, 104/13 = 8
Hence, we get that every student will get 8 candies.

Answer:
[tex]D)\ 25\%[/tex]
Step-by-step explanation:
The following equation can be used to relate the speed time and distance of an object in motion,
[tex](Speed)*(Time)=(Distance)[/tex]
One can also rewrite this equation in terms of time:
[tex](Speed)=\frac{(Distance)}{(Time)}[/tex]
Let this equation represent the relation between Mr.Wang's initial speed and travel time. However, in this problem, Mr.Wang faced a decrease in his speed, more specifically, a (20%) decrease. Subtract (0.2) from (1) to find Mr.Wang's speed in relation to his original speed. Let (x) represent the increase in time that Mr. Wang had to incur in order to reach his destination. Model this situation,
[tex](Speed)*(Time)=(Distance)[/tex]
[tex]0.8(Speed)*x(Time)=(Distance)[/tex]
Now use inverse operations to solve for the coefficient (x):
[tex]0.8(Speed)*x(Time)=(Distance)[/tex]
[tex]x(Time)=\frac{(Distance)}{0.8(Speed)}[/tex]
Using the relation state above: ([tex](Speed)=\frac{(Distance)}{(Time)}[/tex]) one can state the following:
[tex]x(Time)=\frac{(Distance)}{0.8(Speed)}[/tex]
[tex]x(Time)=\frac{1}{0.8}(Time)[/tex]
Thus, (Time) can be omitted from this equation, as it appear on both sides as a factor, hence one can then solve for (x):
[tex]x(Time)=\frac{1}{0.8}(Time)[/tex]
[tex]x=\frac{1}{0.8}[/tex]
Divide (1) by (0.8):
[tex]x=\frac{1}{0.8}\\x=0.25[/tex]
Multiply the decimal by (100) to put it into the percent form:
[tex]x=0.25\\x=25\%[/tex]

Solve each proportion
Answer:
[tex] \frac{11}{b - 1} = \frac{6}{b + 1} \\ 11(b + 1) = (b - 1).6 \\ 11b + 11 = 6b - 6 \\ 11b + 11 - 11 = 6b - 6 - 11 \\ 11b - 6b = 6b - 17 - 6b \\ 5b = - 17 \\ \frac{5b}{5} = \frac{ - 17}{5} \\ b = \frac{ - 17}{5} \\ b = - 3.4[/tex]
[tex]\boxed{\underline{\bf \: Answer}}[/tex]
[tex] \sf \frac{11}{b + 1} = \frac{6}{b + 1} \\ [/tex]
Multiply both sides of the equation by [tex]\left(b-1\right)\left(b+1\right)[/tex], the least common multiple of b-1,b+1.
[tex]\sf\left(b+1\right)\times 11=\left(b-1\right)\times 6 [/tex]
Use the distributive property to multiply b+1 by 11.
[tex]\sf11b+11=\left(b-1\right)\times 6 [/tex]
Subtract 6b from both sides.
[tex]\sf11b+11-6b=-6 [/tex]
Combine 11b and -6b to get 5b.
[tex]\sf5b+11=-6 [/tex]
Subtract 11 from both sides.
[tex]\sf5b=-6-11 [/tex]
Subtract 11 from -6 to get -17.
[tex]\sf5b=-17 [/tex]
Divide both sides by 5.
[tex]\sf \: b=\bf\frac{-17}{5} [/tex]
=> The correct answer is [tex]\bf \: b=\frac{-17}{5} [/tex] or [tex]\bf \: b= -3.4 [/tex] (✓).

Can someone please explain how to find a cofunction with the same value as the given expression. Please explain step by step.
Ex. How would you find the cofunction of sin 7°
Answer:
Step-by-step explanation:
-the angles need to add to 90° because they have to e complementary
- the cofunctions come in pairs (sin and cos, tan and cot, sec and csc)
for sin 7°
we know that function sin is paired with cos , and that the angles needs to add to 90° so we have 7° + 83° =90°
sin 7° = cos 83°, cos 83° is a cofunction of sin 7°

Answer: 86 ÷ x or 86 / x
Step-by-step explanation:
A quotient is a number that results when one number is divided by another.
Therefore, in order to get the quotient, numbers or terms should process division which the final answer would be quotient.
In the process, [÷ ] or [/] the division signs shall be applied.
The quotient of 86 and x represents 86 divided by x, which the final result would be [tex]\boxed {86/x}[/tex]

Step-by-step explanation:
8(b ÷ 2) - (c + 4)
(Putting values of b = 1/2 and c = 1/4)

[tex] = 8( \frac{1}{2} \times \frac{1}{2} ) - ( \frac{1 + 16}{4} )[/tex]
[tex] = 8 \times \frac{1}{4} - \frac{17}{4} [/tex]
[tex] = 2 - \frac{17}{4} [/tex]

Answer:
It is A). -9/4
Step-by-step explanation:
[tex]8(b \div 2) - (c + 4)[/tex]
when b is ½ and c is ¼ :
[tex] = 8( \frac{1}{2} \div 2) - ( \frac{1}{4} + 4) \\ \\ = 8( \frac{1}{4} ) - ( \frac{17}{4} )[/tex]
open brackets:
[tex] = \frac{8}{4} - \frac{17}{4} [/tex]
from LCM formular:
[tex] = \frac{8 - 17}{4} \\ \\ = \frac{ - 9}{4} [/tex]

f =
Answer:
f = - 3
Step-by-step explanation:
Given
- 9(- 2f - 8) = - 6f ← distribute left side
18f + 72 = - 6f ( add 6f to both sides )
24f + 72 = 0 ( subtract 72 from both sides )
24f = - 72 ( divide both sides by 24 )
f = - 3
