Answer:
350
Step-by-step explanation:
First off, remember that $100 is only added once as a deposit. Now we need to figure out what $50 times 5 is. We can calculate that is equals $250
Now we need to add the deposit onto the total.
250+100= 350

what are the prime factorization of 25
Answer:
25 = 5^2
Step-by-step explanation:
Factor the following integer:
25
Hint: | Is 25 divisible by 2?
25 is not divisible by 2 since 25 is odd and 2 is even:
25 = 25 (25 is not divisible by 2)
Hint: | Is 25 divisible by 3?
The sum of the digits of 25 is 2 + 5 = 7, which is not divisible by 3. This means 25 is not divisible by 3:
25 = 25 (25 is not divisible by 2 or 3)
Hint: | Is 25 divisible by 5?
The last digit of 25 is 5, which means 25 is divisible by 5:
25 = 5 5:
25 = 5×5 (5 is not divisible by 2 or 3 since 25 is not)
Hint: | Now try to factor 5. Is 5 prime?
No primes less than 5 divide into it. Therefore 5 is prime:
25 = 5×5
Hint: | Express 25 as a prime power.

The solution of the given expression a(2x+3) = 9x+15+x is 5.
What is an expression?
A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.
An expression is a mathematical proof of the equality of two mathematical expressions.
Given the expression,
a(2x+3) = 9x + 15 + x
Divide both sides by 2x + 3
a = (9x + 15 + x)/(2x + 3)
a = (10x + 15)/(2x + 3)
a = 5(2x + 3)/(2x + 3)
a = 5
Hence "The solution of the given expression a(2x+3) = 9x+15+x is 5".

What is the sum of 23/25 + 9/30
Answer:
61/50
Step-by-step explanation:
1*a = a
1 = b/b
then:
23*25 * 1 = (23/25)(12/12) = (23*12)/(25*12) =276/300
9/30 *1 = (9/30)(10/10) = (9*10)/(30*10) = 90/300
then:
(23/25) + (9/30) = (276/300) + (90/300)
= (276+90)/300
= 366/300
= 122/100
= 61/50
The addition of the fraction 23/25 + 9/30 is equal to 61/50.
What is a fraction?A fraction represents a part of a number or any number of equal parts.
'a/b' of a quantity means that quantity is first divided in 'b' parts, and then mutiplied by 'a', or,
Once the denominators become same, the numerators can add up directly, giving us the final result of addition.
1*a = a
1 = b/b
then:
23*25 * 1 = (23/25)(12/12)
= (23*12)/(25*12) =276/300
9/30 *1 = (9/30)(10/10)
= (9*10)/(30*10) = 90/300
Now add the terms;
(23/25) + (9/30) = (276/300) + (90/300)
= (276+90)/300
= 366/300
= 122/100
= 61/50
Therefore, the addition of the fraction 23/25 + 9/30 is equal to 61/50.

Un terreno A, tiene un largo de 120 m. Y un ancho de 200 m. . Si es 3 veces más largo y 4 veces más ancho que el terreno B. ¿Cuál es el área del terreno B?
Answer:
El área del terreno B es 2000 m.
Step-by-step explanation:
Tenemos que el terreno A es:
[tex]L_{A}[/tex]: largo = 120 m
[tex]A_{A}[/tex]: ancho = 200 m
Y que el terreno B es:
Largo:
[tex] L_{A} = 3L_{B} [/tex]
[tex] L_{B} = \frac{L_{A}}{3} = \frac{120 m}{3} = 40 m [/tex]
Ancho:
[tex] A_{A} = 4A_{B} [/tex]
[tex] A_{B} = \frac{A_{A}}{4} = \frac{200}{4} = 50 m [/tex]
Entonces, asumiendo que el terreno es un rectángulo, el área del terreno B es:

The length of a rectangle picture is 5 inches more than three times the width. Find the dimensions of the picture if it's perimeter is 74 inches.
Answer:
length = 29 incheswidth = 8 inchesStep-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 74 in
The statement
The length of a rectangle picture is 5 inches more than three times the width is written as
l = 5 + 3w
Substitute the expression into the above formula and solve for the width
That's
74 = 2(5 + 3w) + 2w
74 = 10 + 6w + 2w
8w = 64
Divide both sides by 8
w = 8
Substitute this value into l = 5 + 3w and find the length
That's
l = 5 + 3(8)
l = 5 + 24
l = 29
The dimensions of the rectangle are
length = 29 inches
width = 8 inches

What is the domain of this function(picture attached)? Due in 2 hours, 15 points and I'll give Brainliest!
Answer:
[tex]x\geq 1[/tex]
B
Step-by-step explanation:
For square root functions, the domain is the restrictions on the x-variable.
Recall that you cannot take the square root of a negative. Thus, all values under the square root must be greater than or equal to 0. Thus, to find the domain, set the expression under the radical sign to greater than or equal to 0 and solve for x:
[tex](x-1)\geq 0[/tex]
Add 1 to both sides.
[tex](x-1)+1\geq 0+1\\x\geq 1[/tex]
Thus, the domain is:
[tex]x\geq 1[/tex]
All real numbers such that x is greater than or equal to 1.
Answer:
[tex]\huge \boxed{x \geq 1}[/tex]
Step-by-step explanation:
The domain of a function is all possible values for x.
There are restrictions on the value of x.
The number in the square root has to be greater or equal to 0 to be defined. Since the square root of a number lesser than 0 will be undefined.
[tex]x-1\geq 0[/tex]
Adding 1 to both sides.
[tex]x-1+1 \geq 0+1[/tex]
[tex]x\geq 1[/tex]
The domain of the function is [tex]x\geq 1[/tex]
All real numbers greater or equal to 1.

A thread is wound 200 times round a reel of diameter 5 cm. Use the value 3 for it to find the approximate length of the thread in metres.
Answer:
Length of the thread = 30 metres
Step-by-step explanation:
Length of the thread in one round of a reel = Circumference of the reel
C = [tex]2\pi r[/tex]
Since radius of the reel = [tex]\frac{\text{Diameter}}{2}[/tex]
= [tex]\frac{5}{2}[/tex]
= 2.5 cm
Circumference of the reel = 2(π)(2.5)
= 5π
= 5×3
= 15 cm
Length of the thread wound in one round around the reel = 15 cm
Since, thread is wound 200 times round a reel, length of the thread
= 200 × 15
= 3000 cm
≈ 30 metres
Therefore, Option (B) will be the answer.

The line m has a slope of 3/4 and passes through the point (-2, 1). Show that the point (82, 63) does or does not
lie on line m. Justify your answer.
Answer: It does not lie on the line m.
Step-by-step explanation:
First using the slope and the point find an equation in slope intercept form and plot in the coordinates (82,63) to see if it fits. If it fits then it lies on line m and if doesn't then it doesn't like on line M.
The slope intercept formula is y = mx +b where m is the slope and b is the y-intercept, so we need to use the coordinates (-2,1) to find the y-intercept.
Plot the coordinates and the slope into the formula to solve for b.
1 = 3/4(-2) + b
1 = -6/4 + b
+6/4 +6/4
b = 10/4
y = 3/4x + 10/4
63 = 3/4(82) + 10/4
63 = 64
