Step-by-step explanation:
I think you have to use the product rule for counting- which is where you multiply the two numbers. I'm not sure if this is right but I hope I helped
Answer:
5 shirts
Step-by-step explanation:
Think of this question like this, where each shirt option (5 options) has a number:
Shirt #1, Shirt #2, Shirt #3, Shirt #4, and lastly Shirt #5
Without using much math, the answer is 5 shirts because every possible outcome (of the 4 shirts Michael must pick to bring on vacation) will leave exactly one shirt that he will not be able to pack. The only possible outcomes that would fit this question would be:
1) Shirt #1, Shirt #2, Shirt #3, and Shirt #4
2) Shirt #2, Shirt #3, Shirt #4, and Shirt #5
3) Shirt #3, Shirt #4, Shirt #5, and Shirt #1
4) Shirt #4, Shirt #5, Shirt #1, and Shirt #2
5) Shirt #5, Shirt #1, Shirt #2, and Shirt #3

The first class has a kids in it, the second has b kids in it, and the third class has c kids in it. The kids from all three classes are divided equally between two buses. How many kids are in each bus?
Answer:
[tex]\dfrac{a+b+c}{2}[/tex]
Step-by-step explanation:
Number of kids in the first class =aNumber of kids in the second class =bNumber of kids in the third class =cThe sum of the kids in the three classes =a+b+c
If they are divided equally between two buses, then we have:
[tex]\text{Number of kids in each of the bus}=\dfrac{a+b+c}{2}[/tex]
There are 20 children in the cast of a class play, and 8 of the children are boys. Of the boys, 4 have a speaking part in the play, and of the girls, 8
do not have a speaking part in the play. If a child from the cast of the play is chosen at random, what is the probability that the child has a
speaking part?
A: 2/5
B: 1/2
C: 3/5
D: 3/4
Taking into account the definition of probability, the correct option is option A.: The probability that the child has a speaking part is [tex]\frac{2}{5}[/tex].
There are 20 children in the cast of a class play, and 8 of the children are boys. Then, realizing the difference between the number of children and the number of boys you get that 12 of the children are girls.
On the other side, of the boys, 4 have a speaking part in the play, and of the girls, 8 do not have a speaking part in the play. Then, calculating the difference between the number of girls there are and the number of them that they do not have a speaking part in the play is obtained: 12 girls - 8= 4 girls. So, of the girls, 4 do not have a speaking part in the play.
Therefore, 4 + 4 = 8 of the children have a speaking part.
Probability is the greater or lesser possibility of a certain event occurring. In other words, probability establishes a relationship between the number of favorable events and the total number of possible events. Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.
[tex]P(A)=\frac{number of favorable cases}{number of possible cases}[/tex]
In this case:
number of favorable cases= 8 of the children have a speaking part.number of possible cases= 20 childrenReplacing in the definition of probability:
[tex]P(A)= \frac{8}{20}[/tex]
Simplifying the fraction:
[tex]P(A)= \frac{2}{5}[/tex]
Then, the correct option is option A.: The probability that the child has a speaking part is [tex]\frac{2}{5}[/tex].

a) 3 ÷ 1/4=12 b) 3 × 1/4 = 3/4 c) 1/4 ÷ 3 = 1/12 d) 3 + 1/4 3 1/4
Answer:
d) 3 1/4
Step-by-step explanation:
The equation for the total distance traveled per day is 1/4 ÷ 3 = 1/12 of the total distance
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total distance traveled per day be represented as A
Now , the equation will be
The distance traveled for the last 3 days = 1/4 of the total distance
So ,
Total distance traveled per day = distance traveled for the last 3 days / 3
Substituting the values in the equation , we get
Total distance traveled per day A = ( 1/4 ) / 3
On simplifying the equation , we get
Total distance traveled per day A = 1/12 of the total distance
Hence , the equation is 1/4 ÷ 3 = 1/12

Find the measure of Angle A
Answer:
49°
Step-by-step explanation:
Lines k and n seem to be parallel, so that means that 7x = 2x + 35 (corresponding angles are congruent), and x = 7. That means that angle A = 2x + 35 = 14 + 35 = 49° (because they are vertical angles).
The measure of <A is 49 degree.

find the value of x in the picture
Answer:
x = 38
Step-by-step explanation:
A straight line is 180°. We are given 134 and 84. We can find the value of ∠QLM and ∠QML by taking the given numbers and subtract it from 180:
180 - 134 = 46
180 - 84 = 96
All triangles add up to 180. And we already have two of the angles in the triangle. So to find x, we take 46 and 96, add, and subtract from 180:
46 + 96 = 142
180 - 142 = 38
Answer:
x = 38
Step-by-step explanation:
∠ KLO and ∠ MLO are adjacent and supplementary, thus
∠ MLO = 180° - 134° = 46°
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ NMO is an external angle of the triangle, thus
x + 46 = 84 ( subtract 46 from both sides )
x = 38

The correct option is Option C: the point (24,8) shows different ratios of gallons of water and plants from other points.
What is the ratio?The ratio is the representation of the fraction where this fraction is represented by the : symbol.
Given in the question number of plants that he watered every day is represented on the x-axis in the coordinate grid.
The number of gallons that he waters every day is represented on the y-axis in the coordinate grid.
We have to check the ratio of the y coordinate and the x coordinate is different from other options.
By checking all the options
Option A: (16,4) ratio of gallons of water and plants that are watered is 4/16= 1/4= 1:4
Option B: (8,2) ratio of gallons of water and plants that are watered is 2/8= 1/4= 1:4
Option C: (24,8) ratio of gallons of water and plants that are watered is 8/24= 1/3= 1:3
Option D: (48,12) ratio of gallons of water and plants that are watered is 12/48= 1/4= 1:4
By analyzing all options, Option A, B, D has a ratio 1:4. and Option C has a ratio 1:3.

There are 1265 students at Cypress Middle School. 42% of the students are enrolled in PE. Which equation could be used to represent the number of students enrolled in PE?
Answer:
0.42* 1265=x
Step-by-step explanation:
There are 1265 students in Cypress Middle School. So we already know one part of the equation. 42% of these students are in PE. So we know that 42% of these 1265 students are in PE. Of these means you probably have to multiply 42% and 1265. 42% = 0.42. So to write an equation we take the 0.42 and 1265 and put it together. Therefore, 0.42 times 1265=x.

Step-by-step explanation:
the ratio for a 3-6-9 triangle is x, 2x, x√3
if x=8, then 2x=16, and x√3 =8√3
it's not A because it is a right angle triangle.
it's not B because the ratio for an isoceles triangle is x:x:x√2. since a and b are not the same value, it can be assumed that it is not the answer
Answer:
c
Step-by-step explanation:
The longest side is hypotenuse.
Using Pythagorean theorem:
c² = a² + b²
16² = 8² + (8√3)²
256 = 256 True, so it is a right triangle.
Short leg = 8, long leg = 8√3
For 30-60-90 right triangle:
short leg = hypotenuse/2 = 16/2 = 8 , true:
long leg = short leg*√3 = 8√3, true.

Answer:
The bench cost $229 and the garden table costs 229 + 96 = $325
Step-by-step explanation:
let the cost of the bench = x
the cost of the garden table = x + 96
x + (x + 96) = 554
