A person runs 1/4 mile in 1/28 hour. What is the persons speed
Answer:
7
Step-by-step explanation:
speed x time = distance
? x time = distance
1/28x = 1/4
1/28x 1/4
_____ = _____
1/28 1/28
1/4 ÷ 1/28
(reciprocal method) 28/1
1/4 × 28/1 (change the equation into multiplication)
1/4 × 28/1 = 28/4 (multiply)
(Simplify) 28/4 ---> 7/1 or 7
final answer:
The persons speed would be 7.
A cylinder-shaped drainage pipe 66 in. long measures 25.12 in. around.
What is the volume of the drainage pipe?
Answer:
Step-by-step explanation:
25.12 inches around means diameter. So radius = 12.56 inches
volume [tex]= \pi r^2 \times h =\pi \times 12.56^2 \times 66 = 32709.44 \ in^3[/tex]
Answer:
The volume of the drained pipe is 32692.11 in ³.
Step-by-step explanation:
Given :-Diameter of drainage pipe = 25.12 in
So, radius , r = 25.12 in = 12.56 in
Height of drainage pipe, h = 66 in.
To Find :-Volume of the drainage pipe
Solution :-We know that,
Volume of cylinder = π × r ² × h
substitute the values
Volume of pipe = 3.14 × (12.56 in)² × 66 in
simplify
Volume of pipe =3.14 ×157.7536 in² × 66in
multiplying ✖ the values
Volume of the pipe = 32,692.11 in ³
Therefore, the volume of the drained pipe is 32692.11 in ³.
Find the circumference of each circle from the given radius or diameter

Dois triângulos semelhantes possuem razão entre suas áreas igual a 9. Se o perímetro de um deles é 10, o perímetro do outro deve ser:
Answer:
O perímetro do outro triângulo deve ser ou de 30 unidades de comprimento, ou de 3.33 unidades de comprimento.
Step-by-step explanation:
Dois triângulos semelhantes possuem razão entre suas áreas igual a 9.
O perímetro tem grau um, enquanto a área tem grau 2. Isto implica que a razão entre os perímetros é a raiz quadrada da razão entre as áreas, então a razão entre os perímetros é de 3.
Se o perímetro de um deles é 10, o perímetro do outro deve ser:
Ou 10*3 = 30, ou [tex]\frac{10}{3} = 3.33[/tex]
O perímetro do outro triângulo deve ser ou de 30 unidades de comprimento, ou de 3.33 unidades de comprimento.
What is the median for this set of data?
28, 32, 15, 19, 24, 26, 22, 32, 30
Step-by-step explanation:
according order 15 , 19,22, 24,26,28,30,32,32. answer is 26
Answer:
Hello There!!
Step-by-step explanation:
26 is the median as you order the numbers smallest to largest.Therefore,it is 15,19,22, 24, 26,28,30,32,32 and the amount of numbers are odd so the median is the middle number.If it was even the two middle numbers would be added together and then divided by 2.
hope this helps,have a great day!!

Please don't be mad if this is incorrect
Also the x's are multiplication symbols and NOT variables
what is the value of x?
Answer:
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180 degrees
so
70 + 35 + x = 180 add like terms
105 + x = 180 subtract 105 from both sides
x = 75
Answer:
75 degrees
Step-by-step explanation
triangles add up to 180 degrees so, 70+35= 105 degrees, 180-105= 75 degrees

There are 2121 students in a school. A PE teacher wants to arrange maximum possible number of students in the field such that the number of rows is equal to the number of columns. How many students are left out in this arrangement?
Answer:
5 students are left out in the arrangement.
Step-by-step explanation:
If the number of rows = the number of columns
Then there must be an equal arrangement
Since the total number of students in the school is 2121
Then, the students that are left out in this arrangement = 2121 - (√2121 X √2121
Note the result of the square root would only consider the whole number, the digits after the decimal point signifies the remaining number that can't fit into the arrangement
so, √2121 = 46.05 (so 46 would be used)
= 2121 - (46 X 46)
= 2121 - 2116 = 5
Therefore 5 students are left out in the arrangement.

Shane and Abha earned a team badge that required their team to collect no less than 2000 cans for
recycling. Abha collected 178 more cans than Shane did.
Write an inequality to determine the number of cans, S, that Shane could have collected.
What is the solution set of the inequality?
Answer:
s + 178 = Abha's Can's
Step-by-step explanation:
Well since Abha collected 178 more cans than Shane, it would be Shane's amount of cans they collected AND 178 cans on top of that.
(i didnt know if you wanted the solution of s or just the equation on how to find s)
Hi can someone please help me with these questions.
Answer:x=3, x=18, x=29, x=30, x=27
Step-by-step explanation: for problems like the first one, the angles add up to 180 since it’s just a straight line.
The second problem is a right angle so 90°. It gives you 2x and 3x. Part + part =whole so you have 5x=90 then just solve.
Angles across from each other are the same so just 145=5x then solve.

I’m struggling in finding the nearest cent, May you please help me
Answer:
$88.48
Step-by-step explanation:
First, we can check the formula for compound interest, which is
[tex]A = P (1 + r)^{n}[/tex] , with A representing the end amount, r representing the interest rate, and n representing the amount of times compounded. We know that the interest rate is 9% (to convert this to a decimal, we can divide it by 100, resulting in 0.09), the end amount is 700, and the amount of times compounded is however many months are in 2 years (there are 12 months per year, and 12 *2 = 24, so 24 times).
Thus, our equation is
[tex]700 = P (1 + 0.09)^{24}\\700 = P (7.911083)\\[/tex]
Divide both sides by 7.911083 to isolate P, and we get
P = 88.48 (rounded to the nearest cent)
Whats the y-intercept of -2x - y=3
What is the product?
Answer:
[tex]21x^{7}y^{11}[/tex]
Step-by-step explanation:
Remove the parentheses and take out the constansts.
[tex](7 x 3) x^{2} x^{5} y^{3} y^{8}[/tex]
Simplify 7 x 3 to 21.
[tex]21x^{2} x^{5} y^{3} y^{8}[/tex]
Use the product rule: [tex]x^{a} x^{b} = x^{a + b}[/tex]
[tex]21x^{2 + 5}y^{3+8}[/tex]
Simplify 2+5 to 7.
[tex]21x^{7}y^{3+8}[/tex]
Simplfiy 3 + 8 to 11.
[tex]21x^{7}y^{11}[/tex]
¿¡ Cuanto es "(8 x 7 + 5 x (-8)) : (-4)" ??
Answer:
-4
Step-by-step explanation:
So like ur last problem do it in order left to right.
[8x7]+5x(-8)/(-4)
56+[5x(-8)/-4
56+(-40)/-4
16/-4=(-4)
Sorry if i did in wrong order.
Lines J and k intersect at point Q and h is a straight line. What is the value of X ?
Answer:
Step-by-step explanation:
Angles on a straight line add up to 180 so 180-135 equals 45. Vertically opposite angles are equal so the second angle inside the triangle equals 100. Henceforth, we can solve this equation:
x +45+100 = 180 (angles in triangle add up to 180)
x+145=180
x=35
Vertically opposite angles are equal so x will become 35.
Hope this helps!

A track coach records the number of miles that he ran per day over the month. The stem-and-leaf plot below summarizes this data.
Answer:
[tex]Mean = 6.70[/tex]
Step-by-step explanation:
Given
See attachment for plot
Required
The mean of the plot
Mean is calculated as:
[tex]Mean = \frac{\sum x}{n}[/tex]
Where
[tex]n = 20[/tex]
Using the given key to read, the plot;
We have:
[tex]Mean = \frac{3.00+3.25+4.25+5.00+..........+8.75+9.50}{20}[/tex]
[tex]Mean = \frac{134.00}{20}[/tex]
[tex]Mean = 6.70[/tex]
