help! what is the meaning of math. what math is useful to us and why? why do we learn math we don’t need to know?
Step-by-step explanation:
We learn math to expand the memory and learn it just in case you need it later on. You will not always have your phone on you so you can't always have a calculator. We learn math that we don't need because it helps us learn other problems just in cause and open you up to new jobs.

in the circle below, the sum of which arcs is equivalent to arc CG?
arc CG = arc CD + arc FG
arc CG = arc CF + arc EG
arc CG = arc CE + arc DG
arc CG = arc CE + arc EG
Answer: arc CG=arc CE+ arc EG
Step-by-step explanation:
The arc CG is the sum of arc CE and arc EG option fourth arc CG = arc CE + arc EG is correct.
What is a circle?
It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have a circle shown in the picture.
As we can see the arc CG is marked on a circle.
CG is the sum of CE and EG.
or
arc CG = arc CE + arc EG
Thus, the arc CG is the sum of arc CE and arc EG option fourth arc CG = arc CE + arc EG is correct.

how to find the area of a generic quadrilateral
Answer:
Area = base × height, or A = b × h for short. Example: If the base of a rectangle has a length of 10 inches and the height has a length of 5 inches, then the area of the rectangle is simply 10 × 5 (b × h) = 50 square inches.

Hi! I believe your answer is C- 2.1 because the number 2 is in the whole number spot and the first number after the decimal is the tenth. So, it's 2 and one-tenth, because there's a one. I hope this helps you! Good luck and have a great day. ❤️
find all the zeros of the polynomial function
x^3-2x^2 +5x-10
Answer: x = [tex]\sqrt{5} , -\sqrt{5}[/tex] , and 2
Step-by-step explanation:
in the first two monomials you can factor out x^2, and on the last pair of two monomials you can factor out 5
so, x^2(x-2)+5(x-2)
some rule out there says you can simplify this to
(x^2+5)(x-2)
to find the zeroes, set it equal to zero
(x^2+5)(x-2) = 0
you can split up the pairs of parenthesis to equal 0
(x^2+5) = 0
(x-2)=0
find x for both equation and you end up with [tex]\sqrt{5} , -\sqrt{5} , and 2[/tex]

A car can travel 476 miles on 14 gallons of gas. Write a proportion relating the distance to the number of gallons. How many miles can the car travel on 17 gallons?
Answer:
578 miles
Step-by-step explanation:
In order to solve this problem, we need to first calculate how many miles the car can travel on a single gallon of gas. To do this we simply divide the 476 miles that the car travelled by the 14 gallons it used to do so.
476 miles / 14 gallons = 34 miles per gallon
Now, we can see that car can travel 34 miles for every gallon of gas it uses. Therefore, in order to calculate the distance, it can travel on 17 gallons, we simply multiply 34 miles by the 17 gallons we will use like so...
34 miles * 17 gallons = 578 miles

two salads for 5.10 each, so 10.20 for both;
now add 10.20 and 4.47 together: you get 14.67
the bill comes to 14.67, but he pays 20.00;
so subtract 14.67 from 20; you get 5.33

The range of g(x)= [[x/2]] is:
A. All real numbers
B. All odd integers
C. All integers
D. All negative numbers
E. All even numbers
The requried range of the given greatest integer function is all integers. Option C is correct.
What are functions?Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Given expression g(x)= [[x/2]],
Since the given expression is the greatest integer function so the range of the function will be all integers as given as,
For example,
x = 3
g(x) = [[x / 2]]
g(3) = [[3 / 2]]
= [1.5]
= 2 [since for greatest integer function [x] = x + 1 or = x]
Thus, the requried range of the given greatest integer function is all integers. Option C is correct.

2 over 9 minus 1 over 3 in simplest form
Answer:
2/9 - 1/3 (If you want to solved: -1/9)
Step-by-step explanation:
2 over 9 is 2/9 minus is just - and 1 over 3 is 1/3 so the equation looks like this: 2/9-1/3
To solve this you need to multiply the 1/3 by 3 on both the denominator and numerator: 2/9-3/9
simplify: -1/9

If it took eight men ten hours to build a wall, how long will it take four men?
Answer:
I want to say 20
Step-by-step explanation:
4 is half of 8, so double the time and its 20.........
Since it took 10 hours for 8 men to build a wall. If you had 4 men build a wall it would most likely take twice as long than if there were 8 men due to less people.
So it would take 20 hours for 4 men to build a wall.

What is the length of each leg of the triangle below?
45
26
90°
45
A. 132
B. V13
C. 1
D. 18
E. 13
OF /26
Answer:
Option (A)
Step-by-step explanation:
From the triangle ABC given in the picture,
Since, ∠BAC and ∠BCA are equal in measure, opposite sides of these angles will be equal.
AB = BC
Therefore, ΔABC is an isosceles triangle.
By applying Pythagoras theorem in ΔABC,
AB² + BC² = AC²
AB² + AB² = AC² [Since, AB = BC]
2(AB)² = AC²
2(AB)² = (26)²
AB² = [tex]\frac{676}{2}=338[/tex]
AB = [tex]\sqrt{338}[/tex]
AB = [tex]\sqrt{169\times 2}[/tex]
= [tex]13\sqrt{2}[/tex] units
Therefore, Option (A) will be the answer.

Yoshio has three peices of fabirc. Each piece of fabric has the same length. The total length of the fabric is 2 1/4 yards. What is the legth of each pice of fabric?
Answer:3/4
Step-by-step explanation:2 1/4/3=3/4
Length of each piece of fabric is [tex]\boldsymbol{\frac{3}{4}}[/tex] yards.
Define length.The term "length" involves the measurement of distance. Length is a variable with the value distance in the International System of Quantities.

A number has a 6 in the tenths place. The number also has a digit whose value is 1/10 the value of the 6 in the tenths place. Which could be the expanded form of the number?
Answer:
The expanded form of the number is
= 6 × 1/10 + 6 × 1/100
= 6/10 + 6/100
= 0.6 + 0.06
The number is = 0.66
Step-by-step explanation:
A number has a 6 in the tenths place. The number also has a digit whose value is 1/10 the value of the 6 in the tenths place. Which could be the expanded form of the number?
We are told that a number has 6 in its tenth place
This means
6/10 = 0.6
The number also has a digit whose value is 1/10 the value of the 6 in the tenths place.
This means
= 6/10 × 1/10 = 6/100
0.6 × 1/10
= 0.06
Hence, the expanded form
= 6 × 1/10 + 6 × 1/100
= 6/10 + 6/100
= 0.6 + 0.06
= 0.66
