Ray collects cars and trucks. Over the years, the number of cars he collected is 8 less than twice
Klio2033 [76]

Answer:

Number of Trucks = 17

Step-by-step explanation:

Given:

Total number of cars and truck = 43

Find:

Number of Trucks

Computation:

Assume

Number of Trucks = x

Number of Cars = 2x - 8

Total number of cars and truck = Number of Trucks + Number of Cars

43 = x + 2x - 8

51 = 3x

x = 17

Number of Trucks = 17

Let me start with the second screenshot :-
To find the scale factor you have to enlarge/ dilate A to get B you have a given side so assume that all sides are dilated to the same extent
 : .   1 \frac{1}{2}  /  \frac{3}{4} = 2


Thus one can say m would be 
      \frac{1}{2} * 2 = 1

And N would be 
      \frac{5}{6}  * 2 =  \frac{10}{6}

Leda makes 73 oatmeal muffins for a bake sale. She accidentally drops five of them and throws them away. She puts as many of the
mamaluj [8]

Answer:

3 oatmeal muffins

Step-by-step explanation:

First, subtract the 5 muffins she dropped from the total:

73 - 5

= 68

Then, divide this by 13:

68/13

= 5.23

We need a whole number of muffins in each container, so round this down to 5.

This means that there can be 5 muffins in each of the 13 containers.

Find how many will be leftover:

5(13)

= 65

68 - 65

= 3

So, there will be 3 oatmeal muffins left

PLEASE HELP WILL GIVE FULL PONITS! 3. Using the known angle, what side is known? What side is unknown? Use opposite, adjacent, o
Artyom0805 [142]

Answer:

The trigonometric ratio that I would use to find the distance from the base of the tower to the keys is the tangent; tan (86°) = height / distance.

Step-by-step explanation:

You can draw a right triangle with angle 86°, opposite leg equal to the height (50 meter) and adjacent leg equal to the distance from the base of the tower to the keys: tan (86°) = 50 m / x

=> x = 50 m / tan(86°)

x = 50 m / 14.30 = 0.98 m
