Answer:
28.32
Step-by-step explanation:
using the formula [tex]a^{2} +b^{2} =c^{2}[/tex], you get [tex]21^{2} +19^{2} =c^{2}[/tex].
then you get [tex]441+361=802[/tex]
your answer needs to be the square root of 802.
the square root of 802 is 28.319604517
Which rounded to the nearest tenths is 28.32

Dillon pays x dollars to get a haircut. He gives the stylist a
25% tip. The expression representing his total cost is
x + 0.25x
Which expression is equivalent and why?
A. 1.025x because adding 25% to the cost of the haircut is the same
as multiplying the cost by 1.025.
B. 1.25x because adding 25% to the cost of the haircut is the same
as multiplying the cost by 1.25.
C. 1.25x because adding $25 to the haircut is the same as
multiplying the cost by 1.25.
D. x(0.25) because the cost of the haircut can be factored out.
Answer:
B
Step-by-step explanation:
the percentage of money to be paid is 125% which is equivalent to 1.25 in fraction
The equivalent expression is" 1.25x because adding 25% to the cost of the haircut is the same as multiplying the cost by 1.25. Option B is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that, Dillon pays x dollars to get a haircut. He gives the stylist a 25% tip. The expression representing his total cost is,x + 0.25x
Expressions that function identically while having distinct appearances are called equivalent expressions. If two algebraic expressions are equivalent, then they both have the same result when the same value of the variable is entered.
=x + 0.25x
=1.25x
Thus, the equivalent expression is" 1.25x because adding 25% to the cost of the haircut is the same as multiplying the cost by 1.25. Option B is correct.

what is the sum of three consecutive even numbers is 30?
Answer:
here:
you can make an equation
x + ( x + 2) + (x + 4) = 30
then by combining like items you get
3x + 6 = 30
then solve
3x = 30 - 6 ; then 3x = 24 , and x = 8
so the three numbers are 8 ; 10 and 12.

A city has 12,575 residents the number of residents grows by 1.6% every year to the nearest whole resident what will the city's population be in 2 years
Answer:
12981
Step-by-step explanation:
Given that :
Initial number of residents = 12575
Yearly growth rate (r) = 1.6%
Population in 2 years :
Using the relation :
Population in t years P(t) :
P(t) = initial population * (1 + growth rate)^t
t = time
Population in 2 years :
P(2) = 12575 * (1 + 0.016)^2
P(2) = 12575(1.016)^2
= 12575 * 1.032256
= 12980.6192
= 12981

Answer:
Step-by-step explanation:
Given equation is,
y = 3x² - 6x + 11
a). y = 3x² - 6x + 11
= 3(x² - 2x) + 11
= 3(x² -2x + 1 - 1) + 11
= 3(x² - 2x + 1) - 3 + 11
= 3(x - 1)² + 8
Comparing this equation with y = a(x - b)² + c
a = 3, b = 1 and c = 8
b). For minimum value of x,
Since, vertex of the graph is given by (b, c),
Minimum value of x will be,
x = b
x = 1
c). Vertex of the parabola → (b, c)
→ (1, 8)
For y-intercept,
By substituting x = 0 in the equation,
y = 3(0 - 1)² + 8
y = 11
Now we can sketch the graph by using the table of input - output values.
x -2 -1 0 1 2 3
y 35 20 11 8 11 20

Question 8 of 8
Find the slope-intercept equation of the line.
Plz help last question
I need the equation plz
Answer:
[tex]y = 2x + 2[/tex]
Step-by-step explanation:
To find the slope you look at how much the line rises after going 1 unit to the right. In this equation it rises 2 after going over, or running, 1 unit to the right. So the rise over run is 2 over 1. It can be represented in a fraction 2/1. The slope is the rise over run, being 2.
The constant in the equation, or the y-intercept, is the point where the line intersects the y axis, the dark vertical line. You can count how many units it is from the origin where the 2 black lines intersect. The y-intercept in this is 2.
The slope is the number bedfore the x and the y intervept is the constant after the x.
Answer:
y = -2x + 2
Step-by-step explanation:
y=mx+b
find slope(m) first:
choose two points: (1,0), (0,2)
(y2-y1)/(x2-x1)
= (2-0)/(0-1)
= 2/-1
= -2

Answer:
The change should Sara receive from the $10 bill is $3.56.
Step-by-step explanation:
Given:
The table shows the prices of some breakfast items at a restaurant.
Item Price
One egg $1.69
Slice of bacon $1.49
Glass of orange juice $1.09
Sara ordered 2 eggs, a slice of bacon, and a glass of orange juice for breakfast.
The sales tax for the order was $0.48.
She paid for her breakfast with a $10 bill.
Now, to find the change should Sara receive from the $10 bill.
Bill for the Sara's breakfast:
2 eggs = 2 x 1.69 = 3.38
A slice of bacon = $1.49.
A glass of orange = $1.09.
The sales tax = $0.48.
Total bill = 3.38 + 1.49 + 1.09 + 0.48 = 6.44
Sara paid for the breakfast bill = $10.
Now, to get the change Sara should receive we subtract the amount of bill from the money Sara paid for the bill:
sara paid for the breakfast bill - total bill
=10 - 6.44
=3.56
Therefore, the change should Sara receive from the $10 bill is $3.56.
hope it helps!
Clare estimates that her brother is 4 feet tall. When they get measured at the doctor’s office, her brother’s actual height is 4 feet, 2 inches.
1.What was the error, expressed in inches?
2.What was the error, expressed as a percentage of the actual height?
Percentage of error by Clare is estimated as 4.1667 %
Height measured by Clare = 4 feet
Height measured by Doctor = 4 feet, 2 inches
Percentage error = ?
Percentage error = Difference/ Actual height *100
Percentage error = (2/ (4*12))*100
Percentage error = 4.1667 %
The accurate height is measured by Doctor, as he have more accurate measurement system.
