People in building ---- x (men, women and children)
children --- y
men + women + children = x
(3/7)x + (5/8)(4/7)x + y = x
3x/7 + 5x/14 + y = x
times 14
6x + 5x + 14y = 14x
14y = 3x
y + 220 =x
sub into the other one
14y = 3(y+220)
11y = 660
y = 60
then 14(60) = 3x ---> x = 280
So we have 280 people in the building.
check: 3/7 of 280 are men = 120
leaving 160 women and children
5/8 of these ot 100 are women
so we have 120 men, 100 women and 60 children!
hope this is right! have a great. day
Answer:
No. It is not an Exponential Equation.
Step-by-step explanation:
Given
By the Definition of Exponential Equation which states.
"The equation is said to be an exponential equation when it has a variable occurred in the exponent and which have the same base."
For Example:
All given below are said to be exponential equations.
which can be rewritten as
Now in the given equation it doesn't have same base neither any means the base can be made same,hence the given equation is not an exponential equation
Well there’s 24 hours in a rotation.. and one rotation is approximately 40075km
40075km to miles is 24901.451 miles
And we need miles per hour
So divide 24901.451 by 24
= 1037.56 mph (rounded to nearest tenth)
-The polynomial has 5 terms.
-The leading coefficient is -2.
-The degree of the polynomial is 7.
-The constant term is 4.
Step-by-step explanation:
A polynomial is an expression which has many terms. Each term is separated by addition or subtraction. The standard form of a polynomial is and is written in descending order by exponent. The highest exponent is known as the degree of the polynomial. The leading term at the beginning has a leading coefficient.
Using the information above, select what applies for -2xy^5+3x^7-10x^3y^6+8x^6+4.
-The polynomial has 5 terms.
-The leading coefficient is -2.
-The degree of the polynomial is 7.
-The constant term is 4.
-The polynomial is in decreasing degree order.
Answer:
.224 / 7 = .032
Step-by-step explanation:
.224 / 7
7 goes into 2 0 times with 2 left over
7 goes into 22 3 times with 1 left over
7 goes into 14 2 times with 0 left over
.224 / 7 = .032
