Answer:
[tex] \sf \large{m=−3}[/tex]
Step-by-step explanation:
Let's solve your equation step-by-step.
10=7−m
Step 1: Simplify both sides of the equation.
10=7−m
10=7+−m
10=−m+7
Step 2: Flip the equation.
−m+7=10
Step 3: Subtract 7 from both sides.
−m+7−7=10−7
−m=3
Step 4: Divide both sides by -1.
−m/−1= 3/−1
m=−3

an angle measures 85.2 less than the measure of its supplementary angle. what is the measure of each angle? it should be 2 angles or answers. please answer quick. i will mark brainliest. thank you
Answer:
47.4°, 132.6°
Step-by-step explanation:
Given the difference of two angles is 85.2° and their sum is 180°, you want to find their measures.
SetupLet the smaller angle be represented by x. Then the larger angle is (x +85.2). Their sum is ...
x +(x +85.2) = 180
SolutionSimplifying the equation, we get ...
2x +85.2 = 180
2x = 94.8 . . . . . . . . subtract 82.5
x = 47.4 . . . . . . . divide by 2
x +85.2 = 132.6
The two angles are 47.4° and 132.6°.

Sample size =
Based on the histogram above, the class width is equal to 4.
Based on the histogram above, the sample size is equal to 37.
What is a class width?In a frequency distribution table, a class width can be defined as the difference between the upper (maximum) and lower (minimum) boundaries of any class in a data set. This ultimately implies that, all classes must all have the same width in a frequency distribution table.
Mathematically, the class width of a data set can be calculated by using this formula:
Class width = (max - min)/n
Where:
max represents the maximum value in a data setmin represents the minimum value in a data set.n represents the number of desired classes.In this context, the class width of this histogram can be calculated as follows;
Class width = max - min
Class width = 5 - 1
Class width = 4.
Furthermore, the sample size can be computed by adding all the frequencies of the corresponding rectangular bars of the histogram as follows;
Sample size = 6 + 10 + 4 + 2 + 7 + 8
Sample size = 37.

Answer:
A irrational
B real
Step-by-step explanation:
Given the value π/7, you want to classify it as whole, integer, real, and/or irrational.
Number classificationAny number that does not have an imaginary part is a real number. Real numbers include integers, whole numbers, and natural numbers, none of which have any fractional part.
Any ratio of integers (with a non-zero denominator) is a rational number. All other real numbers are irrational numbers. Pi (π) is an irrational number.
When rational numbers are written as decimal numbers, their fractional part will either terminate or repeat. When the fractional part of a decimal number does not terminate or repeat, but continues indefinitely, the number is irrational.
Pi/7As we said, pi is an irrational number. Multiplying it by a rational number (1/7) does not change its classification.
π/7 is irrational and real
5. Daunte's favorite video game store is running a clearance sale. Every week until
everything is sold, the store's owner is going to reduce the price of the remaining
merchandise by 25%. Duante figures that he should wait 4 weeks to go to the
store because then the merchandise will be 100% off! Construct a mathematical
argument involving an exponential function to explain whether Daunte is correct
or incorrect.
Daunte is incorrect. After 4 weeks, the price would be 68.5 percent off.
Is Daunte correct?An exponential function is a mathematical function that has the form : f(x) = a^x
Where:
a = constant x = variableAn exponential function indicates that the quantity is either increasing at a faster rate or reducing at a faster rate. This is true because an exponential increase or decrease is faster than a linear increase or decrease. In a linear increase or decrease, the function is either increasing or decreasing at a constant value.
The price of the video games would reduce by 25% of the previous weeks' price. Thus, the function that would represent this is an exponential function.
The form of the exponential equation would be:
Price after 4 weeks = Initial price x (1 - percentage decrease)^number of years
Let's assume that the initial price is 100
100 x (1 - 0.25)^4
100 x (0.75)^4 = 31.64
The total percentage decrease in the price of the good: (current price initial price) - 1
(31.64 / 100) - 1 = 0.684 = 68.4%

a rectangle with a diagonal of length x is twice as long as it is wide. what is the area of the rectangle?
The area of the rectangle whose diagonal is twice its width is (x²√3)/4 square units.
What is the Area of Rectangle?The area of rectangle is defined by the product of its length and width. Mathematically-
Area [A] = Length [L] x Width [W]
Given is a rectangle whose diagonal is twice as long as it's width. From this, we can write -
Width = w
Length of diagonal = x = 2w
Assume that the length of the rectangle is L. Using the Pythagoras theorem in the triangle ΔABC, we get -
AC² = AB² + BC²
x² = L² + w²
(2w)² = L² + w²
4w² = L² + w²
L² = 3w²
L = w√3
Now, the width of rectangle is 'w' and its length is 'w√3'. Its area will be-
Area = length x width
A = w√3 × w
A = w²√3
Now, length of diagonal → x = 2w. So, we can write -
w = x/2
Therefore, the area will be -
A = (x/2)²√3 = (x²√3)/4
Therefore, the area of the rectangle whose diagonal is twice its width is (x²√3)/4 square units.
