(1 mile = 1,609 meters)
(1 mile = 1,760 yards)
Step 1: 6,436 meters multiplied by conversion factor 1 mile over 1,609 meters equals 4 miles
Step 2: conversion factor of 1,760 yards over 1 mile divided by 4 miles equals 440 yards
Step 3: 440 yards
(1 mile = 1,609 meters)
(1 mile = 1,760 yards)
How can the error in the student's work be corrected? (1 point)
a
The 6,436 meters and the 1,609 meters in Step 1 should be switched.
b
The 1 mile and the 1,609 meters in Step 1 should be switched.
c
The conversion factor should be multiplied in Step 2 instead of being divided.
d
The conversion factor should be added in Step 2 instead of being divided.
Answer:
You usually wouldn't divide lengths
Step-by-step explanation:
Answer:
65.4
for this triangle we use the SOHCAHTOA rules because it is a right angled triangle.
so the rule used here is
we cross multiply both sides
the question said to the nearest tenth, so 65.4 is the final answer
additional $3 per trip down the water slides. If Carla goes on a certain number of trips down
the water slides, the two options are equivalent in terms of cost. How many trips is that?
What is the cost?
Answer: $31 & It would be 6 trips!
Step-by-step explanation: 6 trips x $3 for the trips, is $18 plus the $13 to get in the park, would be equivalent to $31
Answer:
if she rides the slides 6 times, the costs will be the same: $31
Step-by-step explanation:
You can write an equation in order to solve this problem. Since you are trying to find how many trips using the (3t + 13) plan are equal to the plan that costs 31, the equation would be:
31 = 3t + 13
= 18 = 3t
= 6 = t
(3t + 13 stands for $3 a trip plus $13 entry fee)
This means that if Carla takes 6 trips using either plan, they will cost the same; both would cost $31.
Given:
The expression is:
To find:
The value of the given expression.
Solution:
We have,
On simplification, we get
Therefore, the value of the given expression is 11025.
2. Regular pentagon PENTA has side lengths that are 9 meters long. To the nearest square meter, find the area of the pentagon.
Area of pentagon PENTA = _____square centimeter
1) Trapezoid BEAR with bases 11.5 and 6.5 and height 8.5, all in cm.
2) Regular pentagon PENTA with side lengths 9 m
The area of each figure, rounded to the nearest integer
1) The area of a trapezoid is given by
... A = (1/2)(b1 +b2)h
... A = (1/2)(11.5 +6.5)·(8.5) = 76.5 ≈ 77
The area of BEAR is about 77 cm².
2) The conventional formula for the area of a regular polygon makes use of its perimeter and the length of the apothem. For an n-sided polygon with side length s, the perimeter is p = n·s. The length of the apothem is found using trigonometry to be a = (s/2)/tan(180°/n). Then the area is ...
... A = (1/2)ap
... A = (1/2)(s/(2tan(180°/n)))(ns)
... A = (n/4)s²/tan(180°/n)
We have a polygon with s=9 and n=5, so its area is
... A = (5/4)·9²/tan(36°) ≈ 139.36
The area of PENTA is about 139 m².
Answer:139 cm squared
The area of a trapezoid is given by
... A = (1/2)(b1 +b2)h
... A = (1/2)(11.5 +6.5)·(8.5) = 76.5 ≈ 77
The area of BEAR is about 77 cm².

Answer:
below
Step-by-step explanation:
First, you must find the total he has: $10
Then, you must find how much he need: $13
Then, you take the smaller number to take away from the greater number: 13-10
Finally, you subtract those two numbers to find the amount the Juan needs: $3
Answer:
he can do things that well give him money
