A model car is 3 3/4 inches long using a scale of 1/2 in = 2feet find the actual length of the car
Answer:
15 feet
Step-by-step explanation:
Set up a proportion where x is the actual length of the car:
[tex]\frac{3\frac{3}{4} }{\frac{1}{2} }[/tex] = [tex]\frac{x}{2}[/tex]
Cross multiply and solve for x:
[tex]\frac{1}{2}[/tex]x = 7[tex]\frac{1}{2}[/tex]
x = 15
So, the actual length of the car is 15 feet

The figure shows a shape formed by two shapes: Half a circle and a trapezium.
The circle has a radius of r=5.2/2=2.6 and the trapezium has a height of h=6.5 and bases b1=5.2 and b2=3.3.
The area of half a circle is:
[tex]\displaystyle A_c=\frac{\pi r^2}{2}[/tex]
Using pi = 3.14:
[tex]\displaystyle A_c=\frac{3.14\cdot 2.6^2}{2}=10.6132[/tex]
The area of the trapezium is:
[tex]\displaystyle A_t=\frac{b_1+b_2}{2}.h[/tex]
[tex]\displaystyle A_t=\frac{5.2+3.3}{2}\cdot 6.5=27.625[/tex]
The total area of the figure is:
[tex]A=10.6132+27.625=38.2382[/tex]
Rouning to the nearest hundredth:
A=38.24

Step-by-step explanation:
Zane has already walked 15 kilometer this week, plus he plans to walk 2 kilometers during each trip to school. How many trips will Zane have to make in all to walk a total of 41 kilometers?
Let the number of trips = x
This is solved as:
41 = 15 + 2x
41 - 15 = 2x
26 = 2x
x = 26/2
x = 13
Therefore, Zane will have make 13 trips in all to walk a total of 41 kilometers

In a game a player wins if he rolls a 6 on a number cube if the number cube is rolled 18 times then what is an reasonable prediction for the number of unsuccsecful rollls
Answer:
the reasonable prediction for the number of unsuccessful rollls is 15 ÷ 18
Step-by-step explanation:
The computation of the number of unsuccessful rolls is as follow:
For a number cube, the probability of getting 6 would be 1 ÷ 6 and for not getting is 5 ÷ 6
Now for 18 rolls i.e. there is 3 group of 6 so the chance of not getting would be 15 ÷ 18
Hence, the reasonable prediction for the number of unsuccessful rollls is 15 ÷ 18
The same is to be considered

Your robot is 3 inches wide. Its legs are 1 inch apart.
For each robot, enter the distance between the legs.
Answer:
I have this homework as well and the correct answer is 1.67
Step-by-step explanation:
The distance between leg for a 5 inch wide robot is 5/3 inches .
Given the relation between width and distance between legs :
3 inches = 1 inch 6 inches = 2 inchesHence, for every 1 inch width , distance between leg is :
1/3 inchesTherefore, For 5 inch width ;
Distance= 1/3 * 5 = 5/3 inchesTherefore, the distance between leg for a 5 inch wide robot is 5/3 inches .

A bucket filled with 40oz of water is poured into an empty bucket at a rate of 8oz per second. How long before both buckets have the same amount of water? write an equation with variables on both sides.
9514 1404 393
Answer:
4t -8t = 8t
2.5 seconds
Step-by-step explanation:
The amount remaining in the full bucket is ...
40 -8t . . . . . ounces, where t is in seconds
The amount in the empty bucket is ...
8t
These are equal when ...
40 -8t = 8t . . . . . an equation with variables on both sides
The solution is ...
40 = 16t
40/16 = t = 2.5
The buckets will have the same amount after 2.5 seconds.
