Josiah skateboarded from his house to school 4 miles away. It takes him 20 minutes. a. If Josiah's speed, in miles per minute, is constant, what is the constant of proportionality. *
b. How many minutes will it take Josiah to skateboard to his friend Sebastian's house, which is 3 miles from school, if he travels at the same rate that he did form his house to school?
Answer: 35 miles
Step-by-step explanation:
If 4 miles is 20 minutes that mean 1 mile is 5 minutes so just add 4+3 which is 7 then multiply that by 5 which is 35 so it takes him 35 minutes to go to his friends house
Given:
Josiah skateboarded from his house to school 4 miles away. It takes him 20 minutes.Josiah's friend Sebastian's house is 3 miles from school.To find:
The constant of proportionality.The time taken by Josiah on his skateboard to Sebastian's housea.
Distance from Josiah's house to school = 4 miles
Time taken by Josiah on a skateboard to cover 4 miles = 20 min
The speed of Josiah's skateboard = S
[tex]Speed=\frac{Distance}{Time}\\\\S=\frac{4 miles}{20 min}\\\\S=0.2 miles/min[/tex]
The Josiah's speed, the constant of proportionality is 0.2 miles per minute.
b.
Distance From school to Sebastian's house = 3 miles
Time taken by Josiah on a skateboard to travel to Sebastian's house from school = t
The Josiah's speed, the constant of proportionality = 0.2 miles/min
[tex]0.2 miles/min=\frac{3 miles}{t}\\\\t=\frac{3 miles}{0.2 miles/min}=15 min[/tex]
The time taken by Josiah on his skateboard to Sebastian's house is 15 minutes.

Alice has 3 pieces of cloth she embroiders different types of designs on each piece of cloth so that each design covers 1/16 of the cloth. How many types of designs can Alice embroider on the three pieces of cloth?
Answer:
48 designs
Step-by-step explanation:
Total pieces of clothes = 3
Area covered by each design on a piece of cloth = 1/16
How many types of designs can Alice embroider on the three pieces of cloth
Number of designs Alice can embroider on 3 pieces of cloth = Total pieces of cloth / area covered by each embroidery
= 3 ÷ 1/16
= 3 × 16/1
= 48
Therefore, Alice can embroidery 48 types of designs on the 3 pieces of clothes

Write the phrase as an algebraic expression and simplify if possible. Let x represent the unknown number
The sum of 3 times a number and -4 , added to 5 times the number
Answer:
(3x + -4) + 5x
Step-by-step explanation:
The algebraic expression is 8x - 4.
What are algebraic expressions?In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operation.
Now it is given that, x represents the unknown number.
And the given statement is,
The sum of 3 times a number and -4 , added to 5 times the number
So numerically it can be written as,
∵ 3 times a number = 3x
∴ sum of 3 times a number and -4 = 3x -4
and,
5 times the number = 5x
So, the algebraic expression we get,
3x - 4 + 5x
Simplifying it we get,
8x - 4
Thus, the algebraic expression is 8x - 4.

Find the are of the green in the circle.
Answer:
25.12 cm²
Step-by-step explanation:
The area of a circle is given by the formula ...
A = πr²
where r is the radius. Here, the diameter is given as 8 cm, so the radius will be half that, or 4 cm. The area is then ...
A = 3.14(4 cm)² = 50.24 cm²
The green shaded part is 1/2 a circle, so is half this area:
