First place a 5 in the tens place, this means we are multiplying 5 by 50. This will subtract 250 from 280, leaving us with 30.
Next place a 6 in the ones place, this means we are multiplying 5 by 6. This will subtract 30 from 30, leaving us with 0.
This means we have found our answer of 56.
Answer:
See explanation
Step-by-step explanation:
Basically, division is just saying "how many numbers would go into this number this many times?" We can break this problem down into 200/5 and 80/5. 200/5 is 40, and 80/5 is 16. 40+16 is 56, so the answer is 56.

in a class of 32 students there are 8 girls who played basket ball and 5 boys who did not
Answers
(a) 12 boys play basketball
(b) See figure 2 below
==========================================================
Explanation:
Part (a)
You are on the right track so far when you wrote the partial table.
There are 15 girls in the class, and 8 girls that play basketball. That must mean 15-8 = 7 girls do not play basketball.
Focusing on the first row only, we'll have 7 go in the second column and 15 go in the third column. The first row is filled out entirely.
There are 32 students and 15 girls. This means there are 32-15 = 17 boys. We'll write 17 at the end of the second row.
The other missing value of this row is 17-5 = 12 to represent the number of boys who play basketball. This is because of the 5 boys that don't play basketball.
To fill out the missing items in the third row, add the columns straight down.
We have 8+12 = 20 basketball players and 7+5 = 12 people who do not play basketball. Notice how 20+12 = 32 along the bottom row to help confirm the correct values.
Check out figure 1 to see the entire two-way frequency table.
We see that there are 12 boys that play basketball.
------------------------------------------------
Part (b)
The previous part detailed how to set up the two-way frequency table.
For this part, we'll be creating the two-way relative frequency table. The keyword "relative" means that we'll divide each item by the grand total 32.
For instance, in the first row & first column we have 8/32 = 0.25; do the same with the other values. Do not round. The reason for this is because each decimal item is a terminal decimal, meaning the digits stop at some point. If your teacher instructs you to round, then be sure to follow those instructions of course.
Check out figure 2 so you can see the two-way relative frequency table.
A result like 0.25 in the first row & first column tells us that 25% of the class is a girl and plays basketball.

Answer:
[tex]A = 256[/tex]
Step-by-step explanation:
Since the hexagon is regular, we know that all of the side lengths are equal. We can find the length of the sides by solving for [tex]l[/tex] in the formula for the area of a hexagon:
[tex]A = \frac{3\sqrt{3}}{2}l^2\\384\sqrt{3} = \frac{3\sqrt{3}}{2}l^2\\384 = \frac{3}{2}l^2\\256 = l^2\\16 = l[/tex]
Now that we have the side length, we can find the area of the square:
[tex]A = l^2\\A = 16^2\\A = 256[/tex]
Answer:
256 in²
Step-by-step explanation:
Area of a Hexagon (To find side length)
A = 3√3 x l² x 1/2384√3 = 3√3 x 1/2 x l²256 = l²l = 16 inArea of square
Area = (Side length)²Area = (16)²Area = 256 in²If the first number is increased by 7 and the second number is reduced by 6 times, the sum of these numbers is 29.

A mouse climbs up a well of 86 meters. It advances 14 meters during the night, but during the day it retreats 2. The mouse will reach the surface on the day:
Answers
Step-by-step explanation:
we assume day and night are equally long.
and the mouse will start at night of day 1.
then, on day 2, it will first retreat 2 meters (during daylight) and then advance 14 meters (at night).
so, on every full day, the mouse will effectively advance 12 meters (-2 + 14 = 12).
with a starting value of 14 (the first night).
so, we are getting an arithmetic sequence
an = an-1 + c
c = 12 in our case.
a1 = 14
a2 = a1 + 12 = 14+12 = 26
a3 = a2 + 12 = a1 + 12 + 12 = 14 + 2×12 = 38
an = a1 + (n-1)×12 = 14 + 12(n-1)
at what n will it reach 86 ?
86 = 14 + 12(n-1) = 14 + 12n - 12 = 2 + 12n
84 = 12n
n = 7
so, on the 7th day the mouse will reach the surface (if we truly count the first starting night day 1 - this is up to your teacher, but I would).

A triangle has side lengths of 7 inches, 12 inches, and c inches. Enter values to write an inequality that describes the possible values for c, the length of the third side of the triangle.
Answers
Answer:
The inequality is: 5<c<19
Length of third side "c" can have values greater than 5 but less than 19
Solution:
Given that,
Length of two sides of triangle are 7 inches and 12 inches respectively
Let the length of third side be "c"
The Triangle Inequality Theorem, states that, the sum of the lengths of any two sides of a triangle is greater than the length of the third side
So we get a inequality as:
Case 1:
Sum of length of two sides of triangle > length of third side
Rewrite,
Case 2:
Let 12 inches be the length of third side
Sum of sides of length 7 and c > 12
Therefore from case 1 and case 2,
Which can be combined,
Therefore the possible values of "c" are:
"c" can have values greater than 5 but less than 19

The steps for the geometry sequence with the help of two terms of the sequence, make a system of equation and solve them to find common ratio and first term.
What is geometric sequence?
Geometric sequence is the sequence in which the next term is obtained by multiplying the previous term with the same number for the whole series.
It can be given as,
[tex]a_n=a_1r^{n-1}[/tex]
Here, a₁ is the first term of the sequence and r is the common ratio.
The fourth term and sixth term given in for the geometric sequence are 3 and 3/16. For the fourth term,
[tex]a_4=a_1r^{4-1}\\3=a_1r^3[/tex] ...1
For the sixth term,
[tex]a_6=a_1r^{6-1}\\\dfrac{3}{16}=a_1r^5[/tex] ....2
On solving, we get, a₁=192 and r=1/4. Thus, the geometric sequence can be given as,
[tex]a_n=a_1r^{n-1}\\a_n=192\times\dfrac{1}{4}^{n-1}[/tex]
Hence, the steps for the geometry sequence with the help of two terms of the sequence, make a system of equation and solve them to find common ratio and first term.

Augustus is trying to make chocolate milk. He has made a 10% chocolate milk solution (this means that the solution is 10% chocolate and 90% milk). He has also made a 25% chocolate milk solution. Unfortunately, the 10% solution is too weak, and the 25% solution is way too chocolaty. He has a whole lot of the 10% solution, but he has only 30 gallons of the 25% solution. How many gallons of 10% solution should he add to the 25% solution to make a mixture that is 15% chocolate?
Answers
Answer:
60 gallons
Step-by-step explanation:
The amount of 10% solution he should add can be found by writing an equation for the total amount of chocolate in the mix.
__
Let x represent the amount of 10% solution that Augustus needs to add to the 30 gallons of 25% solution. The amount of chocolate in the resulting 15% mix is ...
0.10x +0.25(30) = 0.15(x +30) . . . . gallons of chocolate in the mix
0.10(30) = 0.05x . . . . . . . . subtract 0.10x +0.15(30)
60 = x . . . . . . . . . . . . divide by 0.05
Augustus should add 60 gallons of the 10% solution to make a 15% mixture.

A rhombus is a quadrilateral whose all sides are of equal length. The measure of the ∠QPR is 42°.
What is a Rhombus?A rhombus is a quadrilateral whose all sides are of equal length, and the opposite are parallel to each other.
The diagonals of a rhombus intersect each other at 90°. Therefore, the measure of ∠QTR can be written as,
∠QTR = 90°
(6y+6) = 90°
6y = 90 - 6
6y = 84
y = 14
Also, the diagonals of the rhombus divide the angle into two equal angles, therefore,
∠QPR = ∠SPR
∠QPR = 3y
∠QPR = 3(14)
∠QPR = 42°
Hence, the measure of the ∠QPR is 42°.

What is the value of y on question 7
Answers
The value of y in the given question will be y = -2x + 26.
What is an equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
The value of y will be calculated as:-
Given the equation :-
4y - 2x = 12
y = x / 2 + 12
Now for two perpendicular lines, the product of the intercepts is -1
m₁ x m₂ = -1
So the new intercept will be
m₂ = -1 / m₁ = -1 / 1 / 2 = -2
So new equation will be
y = -2x + c
2 = -2 x 12 + c
c = 26
So the equation will be:-
y = -2x + 26
Therefore the value of y in the given question will be y = -2x + 26.

Answers
Answer:
new equation: 2x +1 = 6 -3x
solution: (x, y) = (1, 3)
Step-by-step explanation:
The Equal Values Method of solving a system of equations has you equate the two expressions that are equal to the same variable or expression. Here, we have two expressions that are equal to y.
equationThe next step is to set them equal to each other:
2x +1 = 6 -3x
__
solutionThis equation can be solved by adding 3x -1 to both sides to get ...
5x = 5
Then dividing both sides by 5 gives ...
x = 1
Substituting into either expression for y gives its value:
y = 2x +1 = 2(1) +1 = 3
The solution to the system is (x, y) = (1, 3).
