Translate the following sentence into an equation. Then, SOLVE the equation: the difference between c and 25 is 75
To translate the sentence into an equation, we can let c represent the value we want to find. The difference between c and 25 is 75, so we can write this as:
c - 25 = 75
To solve the equation, we can add 25 to both sides:
c - 25 + 25 = 75 + 25
c = 100
So the value of c is 100.

what is a = b =c =and y - intercept for the equation y = - 3x^2 + 15
a=-3, b=0, c=15
y-intercept: 15
1) In this quadratic equation, we can tell the following about their coefficients.
\(a=-3,\:b=0,\:c=15\)2) The y-intercept, in a quadratic equation, is always the coefficient "c". So, we can tell that:
\(y-intercept:\:15\)identify the surface whose equation is given. rho2(sin2(φ) sin2(θ) + cos2(φ)) = 81
The equation involves both sin²(φ) and cos²(φ), as well as sin²(θ), which indicates that the surface has a more complex shape, possibly involving rotational symmetry.
To identify the surface whose equation is given as ρ²(sin²(φ) sin²(θ) + cos²(φ)) = 81, we can follow these steps:
Rewrite the equation
We have the equation: ρ²(sin²(φ) sin²(θ) + cos²(φ)) = 81
Isolate ρ²
We can rewrite the equation as: ρ² = 81 / (sin²(φ) sin²(θ) + cos²(φ))
Find ρ
Take the square root of both sides to find ρ: ρ = √(81 / (sin²(φ) sin²(θ) + cos²(φ)))
The given equation represents a surface in spherical coordinates (ρ, φ, θ). Since ρ (the radial distance) is expressed in terms of φ and θ, the surface is not a simple sphere or ellipsoid. The equation involves both sin²(φ) and cos²(φ), as well as sin²(θ), which indicates that the surface has a more complex shape, possibly involving rotational symmetry.
However, without further information, it's difficult to provide a specific name for this type of surface.

Use the following statements to write a compound
statement for the disjunction -p or -q. Then find its truth
value.
p: There are 14 inches in 1 foot.
q: There are 3 feet in 1 yard.
The disjunction of -p or -q can be written as (-p) v (-q). So, we have to find the truth value of (-p) v (-q). So, the compound statement for the disjunction of -p or -q is (-p) v (-q), and its truth value is true.
using the following statements: p: There are 14 inches in 1 foot.
q: There are 3 feet in 1 yard.
Solution: We know that 1 foot = 12 inches, which means that there are 14 inches in 1 foot can be written as 14 < 12. But this statement is false because 14 is not less than 12. Therefore, the negation of this statement is true, which gives us (-p) as true.
Now, we know that 1 yard = 3 feet, which means that there are 3 feet in 1 yard can be written as 3 > 1. This statement is true because 3 is greater than 1. Therefore, the negation of this statement is false, which gives us (-q) as false.
Now, we can use the values of (-p) and (-q) to find the truth value of (-p) v (-q) using the disjunction rule. The truth value of (-p) v (-q) is true if either (-p) or (-q) is true or both (-p) and (-q) are true. Since (-p) is true and (-q) is false, the disjunction of (-p) v (-q) is true. Hence, the compound statement for the disjunction of -p or -q is (-p) v (-q), and its truth value is true.

I'll calculate the surface area to answer your question.
Area of the base and top = 2x20x7 = 280 in^2
Area of the frontal and behind faces = 2 x 7x7.5 = 105 in^2
Area of the left and right faces = 2x20x7.5 = 300 in^2
Total area = 280 + 105 + 300

1.Find by factors the square root of 3600
2. Find by factors the cube root of 343
Answer:
1)60
2)7
Step-by-step explanation:
1)The square root of 3600 is 60. It is the positive solution of the equation x2 = 3600. The number 3600 is a perfect square.
2)The cube root of 343 is the number which when multiplied by itself three times gives the product as 343. Since 343 can be expressed as 7 × 7 × 7. Therefore, the cube root of 343 = ∛(7 × 7 × 7) = 7.
Answer:
Step-by-step explanation:
Note that 3600 can be rewritten as (60)(60) and that the square root of (60)(60) is 60. Thus, the square root of 3600 is 60.
Dividing 343 by 7 yields (7)(49), which factors further into (7)(7)(7).
The cube root of (7)(7)(7) is 7.
A playground is in the shape of a rectangle. The length of the rectangle is three times its width. The area of the playground is 19,500 square feet. What is the length of the playground? Round to the nearest foot. Hint: use A=LW
The length of the rectangular playground is 241.86 foot.
How to calculate length of the rectangle?Given that area of rectangle is 19,500 sq.ft and length of rectangle is three times its width.The area for rectangle is given by formula: A=LW.
Now according to the given condition, L= 3W. Further we'll solve by putting L= 3W in the formula for rectangle.
Calculation:A=LW
As given A= 19,500 sq.ft and considering L=3W,
19,500 = 3W*W
19,500 = 3W^2
∴ W^2 = 6500
∴ W = \(\sqrt{6500}\)
∴ W = 80.6225 ft. ≈ 80.62 ft.
Now putting the value W = 80.62 in equation L =3W,
L = 3* 80.62
L = 241.86 ft.
The length of the rectangular playground is 241.86 foot.

Sofia and Manuel are purchasing a home. They wish to save money for 15 years and purchase a house that has a value of $200,000 with cash. If they deposit money into an account paying 5% interest, how much do they need to deposit each month in order to make the purchase? Round your answer to the nearest cent, if necessary.
Answer:
Monthly deposit= $745.76
Step-by-step explanation:
Giving the following information:
Future Value (FV)= $200,000
Number of periods= 15*12= 180 months
Interest rate= 0.05/12= 0.0042
To calculate the monthly deposit, we need to use the following formula:
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (200,000*0.0042) / [(1.0042^180) - 1]
A= $745.76
The diagram shows a star made by surrounding a
regular octagon with triangles.
Explain why angle a must be 135°.
a
Answer:
see explanation
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
an octagon has 8 sides , then
sum = 180° × 6 = 1080°
the octagon has 8 congruent interior angles , then
a = 1080° ÷ 8 = 135°
Answer:
Step-by-step explanation:
the formula to calculate the sum of interior angles of a polygon is given by (n - 2) × 180°.
So, since the octagon has 8 sides, the sum of the interior angles will be (8 - 2) × 180° = 1080°.
1080 : 8 = 135°

Solve the congruence equation 11x ≡ 4 (mod 31)
"
The solution to the congruence equation 11x ≡ 4 (mod 31) is x ≡ 14 (mod 31).
To solve the congruence equation 11x ≡ 4 (mod 31), we can use the method of modular inverse.
First, we need to find the modular inverse of 11 modulo 31. The modular inverse of a number a modulo m is another number b such that (a * b) ≡ 1 (mod m).
To find the modular inverse of 11 modulo 31, we can use the extended Euclidean algorithm or observe that 11 * 19 ≡ 209 ≡ 1 (mod 31). Therefore, the modular inverse of 11 modulo 31 is 19.
Now, we can multiply both sides of the congruence equation by the modular inverse of 11 modulo 31:
19 * 11x ≡ 19 * 4 (mod 31)
209x ≡ 76 (mod 31)
Simplifying further:
x ≡ 76 ≡ 14 (mod 31)
So, the solution to the congruence equation 11x ≡ 4 (mod 31) is x ≡ 14 (mod 31).

PLEASE PLEASE HELP Write in standard form: a line that passes through (-1, 1) and has slope 2
Answer:
2x - y = - 3
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = 2 , then
y = 2x + c ← is the partial equation
to find c substitute (- 1, 1 ) into the partial equation
1 = - 2 + c ⇒ c = 1 + 2 = 3
y = 2x + 3 ← in slope- intercept form
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
rearranging the slope- intercept form of the equation from above
2x + 3 = y ( subtract y from both sides )
2x - y + 3 = 0 ( subtract 3 from both sides )
2x - y = - 3 ← in standard form

In οther wοrds, the percentage is defined as hοw much οf οne quantity is made by anοther quantity and it is evaluated in terms οf 100.
A) Let x be the unknown percentage.
