Ms. Barcht Open a savings account with $50 and deposit $25 every week. Mrs. Greene save $75 every week. How many weeks will Mrs. Greene have more money in her account than ms. Bracht?
A. 25x+75>50
B. 75x=25x+50
C. 75x>25x+50
D. 75x<25x+50
Answer:
C
Step-by-step explanation:
Ms. Barcht's savings account can be modeled with the expression
50 + 25x
Mrs. Greene's savings account can be modeled with the expression
75x
Since the question is how many weeks Mrs. Greene will have more money than Ms. Bracht. we use an inequality to contain the all the solutions.
Mrs.Greene > Ms. Bracht
75x > 25x + 50
Answer:
The answer would be C. 75x>25x+50
Step-by-step explanation:
The answer would be C. because Ms. Barcht started with $50 and deposits $25 every week while Mrs. Greene saves $75 a week. 7 days is a week so lets multiply $25 x 2 (2 weeks). Ms. Barcht would have $100 by the end of 2 weeks and Mrs. Greene would have $150 by the end of 2 weeks because $75x2 is $150
Hope this helps.

The sum of three consecutive even numbers is 582. What is the 1st number?
Answer:
192
Step-by-step explanation:
Answer: The first number is 192 .
Step-by-step explanation:
Let the three consecutive even numbers
be x , x+2 and x +4 .
Their sum = 582
x + (x+2) + (x+4) = 582
x + x +2 + x +4 = 582
3x + 6 = 582
3x = 582 - 6
3x = 576
x =
x = 192
First number = 192
Second number = 192 + 2 = 194
Third number = 192 + 4 = 196

Answer:
a. 754cm³ (3 s.f.)
b. 415cm² (3 s.f.)
Step-by-step explanation:
Formulas (for easier reference):
Volume of cone: [tex]\pi[/tex]r²[tex]\frac{h}{3}[/tex]
Volume of hemisphere: [tex]\frac{2}{3}[/tex][tex]\pi[/tex]r³
Surface area of cone without base: [tex]\pi[/tex]rl
Surface area of hemisphere without base: 2[tex]\pi[/tex]r²
We can just apply the formulas for the question:
Volume of toy = ([tex]\pi[/tex] × 6² × [tex]\frac{8}{3}[/tex]) + ([tex]\frac{2}{3}[/tex] × [tex]\pi[/tex] 6³)
= 96[tex]\pi[/tex] + 144[tex]\pi[/tex]
= 240[tex]\pi[/tex]
= 754cm³ (3 s.f.)
Surface area of toy = ([tex]\pi[/tex] × 6 × 10) + (2 × [tex]\pi[/tex] × 6²)
= 60[tex]\pi[/tex] + 72[tex]\pi[/tex]
= 132[tex]\pi[/tex]
= 415cm² (3 s.f.)

(⅚x + 10) - (⅙x -5)
***Be Careful - that minus sign is subtracting BOTH terms in the 2nd parentheses.
Answer: 2/3x + 15
Step-by-step explanation:
(⅚x + 10) - (⅙x -5)
The first thing to do here is to open the bracket. This will be:
= ⅚x + 10 - ⅙x + 5
= ⅚x - ⅙x + 10 + 5
= 4/6x + 15
= 2/3x + 15

if f(x)=x-5, find x when f(x)=15
Answer:
x = 20
Step-by-step explanation:
we are given the value of f(x), replace it in the first equation
15 = x - 5
solve for x by adding 5 on both sides
15 + 5 = x
20 = x or x = 20
The value of x is 20.

find the domain of the following equations and solve them
Answer:
Domain → x > 0
Solution → x = 100
Step-by-step explanation:
Given equation is,
[tex]x^{0.5\text{logx}}=0.01x^2[/tex]
Since, log of any number 'x' is defined when x > 0
Therefore, domain of the equation → x > 0
By taking log on both the sides of the equation,
[tex]\text{log}(x^{0.5\text{logx}})=\text{log}(0.01x^2)[/tex]
0.5(logx)(logx) = log(0.01) + log(x²)
0.5(logx)²= -2 + 2log(x)
Let log(x) = a
Then the equation becomes as,
0.5a² = -2 + 2a
0.5a² - 2a + 2 = 0
a² - 4a + 4 = 0
(a - 2)² = 0
a = 2
Since, a = log(x)
log(x) = 2
x = 10²
x = 100
Therefore, solution of the given equation is x = 100.
[tex]\boxed{\boxed{\pink{\tt \leadsto The \ domain \ of \ x \ is \ (0,\infty ). }}}[/tex]
Step-by-step explanation:A equation is given to us and need to find the domain of the equation . So , given equation is ,
[tex]\bf\implies x^{0.5\:log\ x } = 0.01x^2 [/tex]
Now , let's simplify this equation to find the domain of x .
[tex]\bf\implies x^{0.5\:log\ x } = 0.01x^2 \\\\\bf\implies x^{0.5\:log\ x } -0.01x^2 =0 \\\\\bf \implies x^{log \:x^{\frac{1}{2}}} - 0.01x^2=0 \\\\\bf\implies x^{log \ \sqrt{x}} - 0.01x^2=0 [/tex]
Now set the argument in log( √x) Greater than or equal to zero to see where the expression is defined. Since the value of log is non - negative.
[tex]\bf\implies \sqrt{x} > 0 \\\\\bf\implies (\sqrt{x})^2>0^2 \\\\\bf\implies x>0\\\\\bf\implies \boxed{\red{\bf x \in ( 0, \infty ) }}[/tex]
In set builder Notation we can write as ,
[tex]\boxed{\red{\bf \{ x | x > 0 \} }}[/tex]
Hence the domain of x is ( 0 , ∞ ) .Consider the equation 2x + 2y=8.
Write an equivalent equation by multiplying the equation by 3.
Does the equation have the same solution set?
6x+ 2y = 24, yes it has the same solution se
2x + 6y =8, no it doesn't have the same solution set.
6x+ 6y = 24, no it doesn't have the same solution set.
6x + 6y = 24, yes it has the same solution set!
O
Answer:
A) 6x + 6y = 24, Yes, they have the same solution set
Step-by-step explanation:
Let's first start by multiplying the equation by 3:
(2*3)x + (2*3)y = 24
6x + 6y = 24
Now lets find the solution set for both:
6y = -6x + 24
y = -x +4
2y = -2x + 8
y = -x +4
Yes, they have the same solution set

An oil company fills 1 over 10 of a tank in 1 over 5 hour. At this rate, which expression can be used to determine how long it will take for the tank to fill completely? (1 point)
a
1 over 5 • 10 hours
b
1 over 10 • 5 hours
c
1 over 5 • 1 over 10 hour
d
5 • 10 hours
Given that,
An oil company fills 1 over 10 of a tank in 1 over 5 hour.
To find,
How long it will take for the tank to fill completely.
Solution,
Let it takes t time to fill the tank completely. It can be calculated as follows :
[tex]t=\dfrac{\dfrac{1}{10}}{\dfrac{1}{5}}\ \text{hours}\\\\=\dfrac{1}{10}\times 5\ \text{hours}[/tex]
Hence, the rate is "1 over 10 • 5 hours ". The correct option is (b).
The area of a rectangle is 24 square centimeters and its side lengths are x centimeters and x+ 2 centimeters,
a. Find the side lengths of the rectangle. Justify your answer.
b. Find the perimeter of the rectangle.
Step-by-step explanation:
area of rectangle= x ( x +2 ) = 24
X2 + 2X = 24
X 2 +2X _24 = 0
(X +6 ) ( X _4 ) = 0
X= 4
X= - 6.......refused
side length of rectangle is 4 , 6
perimeter= 2( 4+6) = 20 Cm
The side lengths are 4cm , 6cm and perimeter of rectangle is 20cm.
What is perimeter of rectangle?The perimeter of a rectangle is the sum of its four sides. Hence,
Perimeter of Rectangle = 2 (Length + Width) units.
What is area of rectangle?The area of the space occupied within the perimeter of a rectangle is called the area of a rectangle. It is calculated by finding the product of the length and breadth of the rectangle.
Area of rectangle = Length * Breath
According to the question
Area of a rectangle = 24 square centimeters
Side length = x+ 2
Side Breath = x
Now,
a> using Formula of Area of rectangle
Area of rectangle = Length * Breath
substituting the value
24 = x * (x+2 )
24 = [tex]x^{2} +2x[/tex]
[tex]x^{2} +2x[/tex] - 24 = 0
[tex]x^{2} + (6-4)x -24 =0[/tex]
(x +6 ) (x-4) = 0
x = -6 , +4
side cannot be negative
Therefore
Breath of rectangle (x) = 4 cm
Length of rectangle (x+2) = 6 cm
b> Perimeter of the rectangle = 2 (Length + Breath) units.
substituting the value
Perimeter of the rectangle = 2 ( 4 + 6 )
= 20 cm
Hence, The side lengths are 4cm , 6cm and perimeter of rectangle is 20cm.

Janet hikes a trail at a local forest each day. The trail is 3.6 miles long, and she has hiked 5 days in the past week. How many miles has Janet hiked in the past week?
Answer:
7.2 miles
Step-by-step explanation:
Janet hikes a trail 3.6 miles long each day. Considering the forth and back path, she trails 2*3.6= 7.2 miles.
Since she has hiked 5 days in the past week, she has hiked 5*7.2 = 36 miles.
The question does not specify if the path back is to be considered. If not, then the total distance traveled is 3.6*5 = 18 miles.
