Carlos wrote a check for $44.92 to pay his gas bill. he’ll use the check register to record his transaction. what will be his new balance? a check register has a balance of 415 dollars and 1 cent. $345.09 $370.09 $434.93 $459.93
Answers
His new balance after the check is deducted will be $370.09
How to determine his new balance?From the question, we have the following parameters:
Initial Balance = $415.01 Check amount = $44.92The new balance is then calculated using:
New balance = Initial Balance - Check
So, we have:
New balance = 415.01 - 44.92
Evaluate
New balance = 370.09
Hence, his new balance will be $370.09

solve for x:2x^2-5x-3=0
Answers
Answer:
The value of x = 3 or -1/2
Step-by-step explanation:
2x²-5x-3=0
=> 2x² - 6x + x - 3 =0
=> 2x ( x - 3) + 1 ( x -3) =0
=> (2x+1) ( x-3) =0
x = 3 or x = -1/2
65. show that of all the isosceles triangles with a given perimeter, the one with the greatest area is equilateral.
Answers
Answer:
Below.
Step-by-step explanation:
I can do this using calculus but the algebra will be a bit messy.
Let the 2 equal sides of isosceles triangle be x and the base be y units long.
Then perimeter p = 2x + y.
Area A = 0.5yh where h is the altitude of the triangle.
h = sqrt [x^2 - (0.5y)^2]
= [x^2 - (0.5y)^2]^0.5
So A = 0.5y * [x^2 - (0.5y)^2]^0.5
From the perimeter formula y = p - 2x so:
A = 0.5(p-2x) * [x^2 - (0.5(p-2x)^2]^0.5
A = 0.5(p-2x) * [x^2 - 0.25(p^2 - 4xp + 4x^2)]^0.5
A = 0.5(p-2x) * [x^2 - 0.25p^2 + xp - x^2]^0.5
A = (0.5p-x) * [xp - 0.25p^2]^0.5
We now find the derivative and equate it to zero to find the value of x which corresponds to a maximum area.
We use the product rule:
dA/dx = (0.5p-x)* 0.5(xp - 0.25p^2)^(-0.5) * p - 1(xp - 0.25p^2)^0.5 = 0
p(0.5p - x) / (2((xp - 0.25p^2)^0.5 - (xp - 0.25p^2)^0.5 = 0
p(0.5p - x) / (2((xp - 0.25p^2)^0.5 = (xp - 0.25p^2)^0.5
Now multiplying though by (2((xp - 0.25p^2)^0.5 :-
p(0.5p - x) = 2 (xp - 0.25p^2)
0.5p^2 - px = 2px - 0.5p^2
p^2 = 3px
x = p^2/3p = p/3
So for a maximum value of the area x = p/3.
But y = p - 2x
= p - 2(p/3)
= p - 2/3p
= p/3
- but we've just shown that x = p/3
That means that x = y and the triangle is Equilateral.

Solution
(1) Find the rate of the cube's edge length with respect to time at s=30:
[tex]\displaystyle V=s^3\\\\\frac{dV}{dt}=3s^2\frac{ds}{dt}\\ \\10=3(30)^2\frac{ds}{dt}\\ \\10=3(900)\frac{ds}{dt}\\\\10=2700\frac{ds}{dt}\\\\\frac{10}{2700}=\frac{ds}{dt}\\\\\frac{ds}{dt}=\frac{1}{270}\text{cm}/\text{min}[/tex]
(2) Find the rate of the cube's surface area with respect to time at s=30:
[tex]\displaystyle SA=6s^2\\\\\frac{d(SA)}{dt}=12s\frac{ds}{dt}\\ \\\frac{d(SA)}{dt}=12(30)\biggr(\frac{1}{270}\biggr)\\\\\frac{d(SA)}{dt}=\frac{360}{270}\biggr\\\\\frac{d(SA)}{dt}=\frac{4}{3}\text{cm}^2/\text{min}[/tex]
Therefore, the surface area increases when the length of an edge is 30 cm at a rate of [tex]\displaystyle \frac{4}{3}\text{cm}^2/\text{min}[/tex].
Mike paid $\$1.25$ for a stamp three years ago. He was just offered double that amount for the stamp. Assuming the stamp's offer price doubles every three years, how many dollars will he be offered in 12 more years
Answers
Answer: $40
Step-by-step explanation:
If the worth of the stamp is double that of its original price 3 years ago ($1.25), the current price of the stamp should be $2.50. If that doubles every 3 years the answer should look something like this:
3 years: $5 (2.50X2=5)
6 years: $10 (5X2=10)
9 years: $20 (10X2=20)
12 years $40 (20X2=40)
In 12 years the stamp will be worth $40.

a) 475.2
b) 52.8
c) 480
d) 580.8
e) 475
Answers
Answer:
c) 480
Step-by-step explanation:
Any percentage can be converted to a number ratio by dividing by 100%.
E.g. 100%/100% = 1
Following this concept, we can find the equivalent of 110% :
110%/100% = 1.1
Since 528 is 1.1 times the number we are looking for, we just need to divide 528 by 1.1 to find our number. This is because 1.1/1.1 = 1
528/1.1 = 480

write the equation of a line:
a) parallel to the line 3x+5y=-10
b) parallel to the line 2y-4x=5 and which goes through the point (3,7)
c) perpendicular to the line 8x+6y=-1 and which goes through the point (-2,1)
THANKS!!
Answers
a) Line parallel to the line 3x+5y=-10 is -6x-10y=9
b) Line parallel to the line 2y-4x=5 and which goes through the point
(3,7) is y= 2x-1.
c) Line perpendicular to the line 8x+6y=-1 and which goes through the
point (-2,1) is 4y= 3x+ 10
The standard form of equation of a line is ax + by + c = 0. Here a, b, are the coefficients, x, y are the variables, and c is the constant term. It is an equation of degree one, with variables x and y.
a) Equation parallel to 3x+5y=-10 is
-6x-10y=9
So, it satisfies: [tex]\frac{a_1}{a_2} = \frac{b_1}{b_2} \neq \frac{c_1}{c_2}[/tex]
b)given equation into the form of y=mx+c,
2y-4x=5
we can find the gradient of the line.
2y= 5+4x
y= [tex]\frac{5}{2}[/tex] + 2x
Hence, the gradient is 2.
As, Parallel lines have the same gradient
Thus the line would also have a gradient of 2.
Substitute m=2 into the equation:
y= 2x +c
To find the value of c, substitute a pair of coordinates.
When x=3, y=7,
7= 2(3) +c
7= 6 +c
c=6-7
c= -1
So, equation of line be: y= 2x-1.
c) Given: 8x+6y=-1
6y= -1-8x
y= [tex]\frac{-1}{6} -\frac{4}{3}x[/tex]
Hence, m= [tex]-\frac{4}{3}[/tex]
We know, if two lines are perpendicular have m and m' as slope then,
m*m'=-1
[tex]\frac{-4}{3} *m'=-1[/tex]
m'= [tex]\frac{3}{4}[/tex]
Now, y= [tex]\frac{3}{4}[/tex] x +c
Put x= -1 and y=1
then, 1= [tex]\frac{3}{4}[/tex] (-2) + c
c= [tex]\frac{5}{3}[/tex]
So, y= [tex]\frac{3}{4}[/tex] x + [tex]\frac{5}{2}[/tex]
4y= 3x+ 10

Answers
No, there is not a rigid transformation or a combination of rigid transformations that will map ABCD to WXYZ.
What is congruency?The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one are congruent to the included angle and corresponding two sides of the other triangle.
Two figures are congruent if their vertices can be mapped into one another by appropriate rigid transformation or a combination of rigid transformations. Examples of the transformation are; reflection, dilation, rotation and translation.
Comparing the two figures, it would be observed that they are not congruent. Since there is not a rigid transformation or a combination of rigid transformations that will map ABCD to WXYZ.
