A construction crew has just finished building a road. The crew worked for 12.6 days. If they built 2.5 kilometers of road each day, find the total length of road
they built.
m
Answer:
They built 31500 m of the road.
Step-by-step explanation:
Given that,
The crew worked for 12.6 days.
The crew built 2.5 km of road each day.
We need to find the total length of the road they built. We can find the total length as follows :
L = 12.6 × 2.5 km
L = 31.5 km
or
L = 31500 m
So, they built 31500 m of road.

Labyrinth Middle School is 363 feet long. Tabitha makes a scale model of the school and the drawing is 33 inches long. What is the scale factor used to create the model? Question 3 options: 11 inches represents 111 {"version":"1.1","math":"111"} of a foot. 1 inch represents 11 feet. 1 inch represents 111 {"version":"1.1","math":"111"} of a foot. 11 inches represents 1 foot
Answer:
1 inch represents 11 feet.
Step-by-step explanation:
Actual length is 363 feet
Scale model is 33 inches.
So, the scale factor is [tex]\frac{33}{363}[/tex]
Simplify it, we get [tex]\frac{1}{11}[/tex]
It means the scale factor is 1 inch for 11 feet.
That's 1 inch represents 11 feet.

Gavin rolls a fair dice 30 times.
How many times would Gavin expect to roll a five?
The expected number of 5's would be rolled is 5 times if the Gavin rolls a fair dice 30 times.
What is probability?
It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Total outcomes = {1, 2, 3, 4, 5, 6]
Total number of outcomes = 6
Favourable outcomes = {5}
Total number of favourable outcomes = 1
Probability of rolling 5 = 1/6
The expected number of 5's would be 30×(1/6) = 5 times
Thus, the expected number of 5's would be rolled is 5 times if the Gavin rolls a fair dice 30 times.

los puntos (1,-2);(-8,4 y (5,2) son los vertices de un triangulo rectángulo su perimetro es aproximadamente
Answer:
El perímetro del triángulo rectángulo es aproximadamente 29.627.
Step-by-step explanation:
Las coordendas de los vértices del triángulo rectángulo son [tex]A(x,y) = (1,-2)[/tex], [tex]B(x,y) = (-8,4)[/tex] y [tex]C(x,y) = (5,2)[/tex]. En primer lugar, determinamos las longitudes de los segmentos AB, BC y AC por el Teorema de Pitágoras:
[tex]AB = \sqrt{(-8-1)^{2}+[4-(-2)]^{2}}[/tex]
[tex]AB \approx 10.817[/tex]
[tex]BC = \sqrt{[5-(-8)]^{2}+(2-4)^{2}}[/tex]
[tex]BC \approx 13.153[/tex]
[tex]AC =\sqrt{(5-1)^{2}+[2-(-2)]^{2}}[/tex]
[tex]AC \approx 5.657[/tex]
El perímetro del triángulo ([tex]p[/tex]) es la suma de todos estos segmentos:
[tex]p = AB + BC + AC[/tex]
[tex]p \approx 29.627[/tex]
El perímetro del triángulo rectángulo es aproximadamente 29.627.

Answer: The answer to your question is 6[tex]\sqrt{3}[/tex]
Step-by-step explanation:
To solve this problem we will use proportions. We will compare the largest right triangle and the medium size triangle.
Medium triangle Large triangle
hypotenuse y 9 + 3
adjacent size 9 y
- Write the proportions
y/9 = (9 + 3)/y
-Solve for y
y² = 9(12)
y² = 108
y = [tex]\sqrt{180}[/tex]
-Find the prime factors of 108
108 2
54 2
27 3
9 3
3 3
1
then, 108 = 2² 3³
-Expressthe root as fractional exponents
2²/² 3²/² 3¹/²
-Simplification
2(3)(3)¹/²
-Result
6[tex]\sqrt{3}[/tex]
2x-y=3 ; 5x+2y=30 solve using elimination
Answer:
x = 4, y = 5
Step-by-step explanation:
[tex]2x-y=3\\4x-2y=6[/tex]
so:
[tex]4x - 2y = 6\\+ 5x + 2y = 30\\9x= 36\\x=4[/tex]
Substitute this into 2x - y = 3:
[tex]8-y=3\\y = 5[/tex]

Jaylen is making pancakes. He has 1 liter of pancake mixture. If Jaylen is using
1/4
liter of mixture for 1 pancake, how many pancakes can he make with the whole mixture? Create an equation and also give the solution.
He can make 4 pancakes with the whole mixture.
Step-by-step explanation:
It is given that,
Jaylen has a total of pancake mixture = 1 liter.
The amount of pancake mixture he uses to make 1 pancake = 1/4 liter.
You need to find the number of pancakes he can make using the 1 liter of pancake mixture.
To find the number of pancakes :
let us take 'N' be the number of pancakes he can make using 1 liter of mixture.
⇒ Total mixture = amount of mixture needed for 1 pancake × N
⇒ 1 liter = 1/4 liter × N
⇒ 1 = N/4
Cross multiply the denominator 4 to the other side, to find N
⇒ 1 × 4 = N
⇒ N = 4 pancakes
Therefore, he can make 4 pancakes with the whole mixture.
