Answer:
26 units
Step-by-step explanation:
Step 1: Determine the y-intercepts of the lines:
The first line y = -5x has a y-intercept of 0 (when x = 0).
The second line y = -5x + 26 has a y-intercept of 26 (when x = 0).
Step 2: Calculate the difference in the y-intercepts:
Difference = |0 - 26| = 26 units
Therefore, the distance between the pair of parallel lines y = -5x and y = -5x + 26 is 26 units.

1) The area of a circle circumscribed about a square is 307.7 cm².
2.a.) The angle ACB is 39 degrees.°.
2b.) The value of x is 5.42.
How to determine the area of a circle?We shall find the radius to determine the area of a circle.
First, find the side length of the square:
Since the perimeter of the square = 56 cm, then, each side of the square is 56 cm / 4 = 14 cm.
Next, find the diagonal of the square, using the Pythagorean theorem:
Diagonal = the diameter of the circumscribed circle.
Diagonal² = side length² + side length²
= 14 cm² + 14 cm²
= 196 cm² + 196 cm²
= 392 cm²
Take the square root of both sides:
Diagonal = √392 cm ≈ 19.80 cm (rounded to two decimal places)
Then, the radius of the circle which is half the diagonal:
Radius = Diagonal / 2 ≈ 19.80 cm / 2 ≈ 9.90 cm (rounded to two decimal places)
Finally, compute the area of the circle using the formula:
Area = π * Radius²
Area = 3.14 * (9.90 cm)²
Area ≈ 307.7 cm² (rounded to two decimal places)
Therefore, the area of the circle that is circumscribed about a square with a perimeter of 56 cm is 307.7 cm².
2. a) We use the property of angles in a circle to solve for angle ACB: an angle inscribed in a circle is half the measure of its intercepted arc.
Given that arc AB has a measure of 78°, we can find angle ACB as follows:
Angle ACB = 1/2 * arc AB
= 1/2 * 78°
= 39°
Therefore, the angle ACB is 39 degrees.
2b.) To solve for the value of x, we use the information that the angle ADB = (3x - 12)⁴.
Given that angle ADB is (3x - 12)⁴, we can equate it to the measure of the intercepted arc AB, which is 78°:
(3x - 12)⁴ = 78
Solve the equation for x, by taking the fourth root of both sides:
∛∛((3x - 12)⁴) = ∛∛78
Simplify,
3x - 12 = ∛(78)
Isolate x by adding 12 to both sides:
3x - 12 + 12 = ∛(78) + 12
3x = ∛(78) + 12
Finally, divide both sides by 3:
x = (∛(78) + 12) / 3
x = (4.27 +12) / 3
x = 5.42
So, x is 5.42
Therefore,
1) The area of the circle is 154 cm².
2a.) Angle ACB is equal to 102°.
2b.) The value of x is 5.42

the sum of two numbers is 59. the didference between the two numbers is 11 which is the smaller of the two numbers
The larger number is 35.Let's assume the two numbers are represented by the variables "x" and "y," where "x" is the smaller number.
Equation 1: x + y = 59 (The sum of the two numbers is 59)
Equation 2: x - y = 11 (The difference between the two numbers is 11, with the smaller number being y)
According to the given information, the sum of the two numbers is 59, which can be expressed as:
x + y = 59
The difference between the two numbers is 11, with "x" being the smaller number. This can be expressed as:
y - x = 11
We can now solve these two equations simultaneously to find the values of "x" and "y."
Rearranging the first equation to solve for "y" gives us:
y = 59 - x
Substituting this value of "y" into the second equation:
(59 - x) - x = 11
Simplifying the equation:
59 - 2x = 11
Subtracting 59 from both sides:
-2x = 11 - 59
-2x = -48
Dividing both sides by -2:
x = -48 / -2
x = 24
Therefore, the smaller number is 24. To find the larger number, we substitute the value of "x" into the first equation:
24 + y = 59
y = 59 - 24
y = 35.

24. What is the cost for 5 t-shirts that cost $10 with a sales tax of 6%?
$3
$56
$50
$53
The cost for 5 t-shirts, including Sales tax, is $53.
The cost of 5 t-shirts with a price of $10 each and a sales tax of 6%, we need to multiply the total price of the t-shirts by the sales tax rate and add it to the original price.
The original price of one t-shirt is $10. Therefore, the total price of 5 t-shirts is:
$10 * 5 = $50
To calculate the sales tax, we need to multiply the total price by the sales tax rate of 6%:
$50 * 6% = $50 * 0.06 = $3
Adding the sales tax to the total price:
$50 + $3 = $53
Therefore, the cost for 5 t-shirts, including sales tax, is $53.
The correct answer is: $53.

How do we solve fractions step by step?
Conversion a mixed number 2 1/3 to a improper fraction: 2 1/3 = 2 1/3 = 2 3 + 1/3 = 6 + 1/3 = 7/3
To find a new numerator
A; Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/3 = 6/3
b) Add the answer from the previous step 6 to the numerator 1. The new numerator is 6 + 1 = 7
c) Write a previous answer (new numerator 7) over the denominator 3.
Two and one-third are seven-thirds.
Conversion a mixed number 1 3/4 to a improper fraction: 1 3/4 = 1 3/4 = 1 · 4 + 3/4 = 4 + 3/4 = 7/4
To find a new numerator:
a) Multiply the whole number 1 by the denominator 4. Whole number 1 equally 1 * 4/4 = 4/4
b) Add the answer from the previous step 4 to the numerator 3. The new numerator is 4 + 3 = 7
c) Write a previous answer (new numerator 7) over the denominator 4. One and three quarters are seven quarters.
Add: 7/3 + 7/4 = 7 · 4/3 · 4 + 7 · 3/4 · 3 = 28/12 + 21/12 = 28 + 21/12 = 49/12 It
is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(3, 4) = 12. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 4 = 12. In the following intermediate step, it cannot further simplify the fraction result by cancelling. In other words - seven thirds plus seven quarters is forty-nine twelfths.
