Answer:
Percent decrease in population = 12%
Step-by-step explanation:
Given that:
Population of city = 160,000
Population of city after several years = 140,800
Difference= 160000 - 140800 = 19200
Percent decrease = [tex]\frac{Difference}{Population} * 100[/tex]
Percent decrease = [tex]\frac{19200}{160000}*100[/tex]
Percent decrease = 0.12 * 100
Percent decrease = 12%
Hence,
Percent decrease in population = 12%

The question is incomplete. Here is the complete question.
m∠J and m∠Kare base angles of an isosceles trapezoid JKLM.
If m∠J = 18x + 8, and m∠M = 11x + 15 , find m∠K.
A. 1
B. 154
C. 77
D. 26
Answer: B. m∠K = 154
Step-by-step explanation: Isosceles trapezoid is a parallelogram with two parallel sides, called Base, and two non-parallel sides that have the same measure.
Related to internal angles, angles of the base are equal and opposite angles are supplementary.
In trapezoid JKLM, m∠J and m∠M are base angles, so they are equal:
18x + 8 = 11x + 15
7x = 7
x = 1
Now, m∠K is opposite so, they are supplementary, which means their sum results in 180°:
m∠J = 18(1) + 8
m∠J = 26
m∠K + m∠J = 180
m∠K + 26 = 180
m∠K = 154
The angle m∠K is 154°

In Game 1, Eli struck out 25 times in 75 times at bat.
In Game 2, he struck out 30 times in 100 times at bat.
In Game 3, he struck out 37 times in 120 times at bat.
struck out
'at bat
What proportion represents the percent of
strike outs per at bats?
Answer:
p = 31.19%
Step-by-step explanation:
Proportions and Percentages
A proportion is calculated as a division between two numbers. The result can be given as a decimal or as a percentage.
If we want to calculate the percent of a number N with respect to another number M, the formula is:
[tex]\displaystyle p=\frac{N}{M}*100\%[/tex]
Eli had some performances when playing baseball. Struck out 25 times in 75 times at bat, 30 times in 100 at-bats, and 37 times in 120 at-bats.
The total struck outs were: N= 25+30+37=92 and the total at-bats were: 75+100+120=295. The proportion of strikeout ber at-bats is:
[tex]\displaystyle p=\frac{92}{295}*100\%[/tex]
p = 31.19%

The function y= x2 - 10x+ 31 has a
value of
Answer:
y = 6 at x = 5Step-by-step explanation:
It is assumed the question is about finding the minimum value as the given function has no maximum value, it is + ∞ as the coefficient of x² is positive
The minimum/maximum value of a quadratic function is the vertex, which is at:
x = -b/2aFor the given function y = x² -10x + 31, the vertex is:
x = - (-10)/2*1 = 10/2 = 5The value of y at this point is:
y = 5² - 10*5 + 31 = 25 - 50 + 31 = 6The point is
(5, 6)Cheryl is buying lace for her dance costume. One foot of lace costs 3 dollars. How much does each amount cost?
3/4 of a foot?
Answer:
3/4 of a foot will cost $2.25.
Step-by-step explanation:
This question is solved by rule of three, due to proportions.
One foot of lace costs 3 dollars. How much is 3/4 of a foot going to cost?
1 foot - 3 dollars
3/4 foot - x dollars
[tex]x = 3 \times \frac{3}{4} = \frac{9}{4} = 2.25[/tex]
So
3/4 of a foot will cost $2.25.
Calculate the volume, in cubic centimeters, of a box which is 125 cm long, 37 cm wide, and 68 cm high. Report your answer with correct significant figures in cubic centimeters.
Answer:
[tex]Volume = 314500cm^3[/tex]
Step-by-step explanation:
Given
[tex]Length = 125cm[/tex]
[tex]Width = 37cm[/tex]
[tex]Height = 68cm[/tex]
Required
Determine the volume
Volume is calculated as:
[tex]Volume = Length * Width * Height[/tex]
Substitute values for Length, Width and Height
[tex]Volume = 125cm * 37cm * 68cm[/tex]
[tex]Volume = 314500cm^3[/tex]
Hence, the volume of the box is [tex]314500cm^3[/tex]

Solve by elimination:
2x + 4y = 34
x+4y = 27
A (7,-5)
B (6,6)
(7,5)
(5,7)
Answer:
(7,5)
Step-by-step explanation:
{2x + 4y = 34
{4y = 27 - x
2x + 27 - x = 34
x=7
4y = 27 - 7
y = 5 so the answer is ( 7,5)
What is the solution to the system of equations below?

O (6,3)
O (3,6).
O (7,-6)
O (-6, 7)
Answer:
6,3
Step-by-step explanation:
given equtions are
x+3y=15______(1)
4x+2y=30______(2)
multiplying (1) by 4
on solving, 4x+12y=60_____(3)
substracting eqution (3) and (2)
4x+12y-(4x+2y)=60-30
⇒10y=30
on solving,
y=3

The system of equations y=-2x+3 and y=x is graohed. What is the solution to the system of equations
Answer:
The solution to this system of equations is y = 1, x = 1
Step-by-step explanation:
We know that...
(1) y = - 2x + 3
(2) y = x
Then we just substitute the value of x that we are given in equation (2).
And so we get....
y = -2x + 3
x = - 2x + 3
3x = 3
x = 1
From equation (2) we know that y = x, so since x equals 1 y is also 1. There for the solution to this system of equations is (1,1)
