A model of a submarine has a length of 6.6 meters. Use the scale 1:35 to find the length

Mathematics

The scale 1:35 indicates that for every 1 meter on the scale model, there are really 35 meters in real life.

So if the scale model is 6.6 meters, you would do 35 * 6.6 to find the length in real life, which is 231 meters.

The answer is 231 meters.

An ice cream shop sells 6 different flavors, 4 toppings, and 3 types of cones. How many different combinations of two different
Bas_tet [7]

Answer:

360 combinations

Step-by-step explanation:

To calculate the number of different combinations of 2 different flavors, 1 topping, and 1 cone, we are going to use the rule of multiplication as:

<u>               6          </u>* <u>        5             </u> * <u>            4           </u>* <u>          3             </u>= 360

       1st flavor           2nd flavor              topping              cone

Because first, we have 6 possible options for the flavor, then we only have 5 possible options for the 2nd flavor. Then, we have 4 options for the topping and finally, we have 3 options for the cone.

It means that there are 360 different combinations of two different flavors, one topping, and one cone are possible

What are the intercepts of the line 2x + 4y = 12?
Darina [25.2K]
<span>if you're finding the x intercept, y is ALWAYS 0, so in this, you can just get rid of the -4y because you know that it's 0, so you're left with 2x=12 divide by 2 on both sides so you find x intercept is (6,0) on the graph 
the y works the same way, if you're looking for the y, you know that the x is zero, so you're left with -4y=12, divide by -4y on both sides and you end up with the y intercept being (0,-3) 

x int.= (6,0) 
y int.= (0,-3) 

by the way, when it's written like that, it's called standard form, so to find the intercepts on 2x=12+4y, you'd have to convert it into standard form (Ax=By=C) so you subtract 4y on both sides to make it 2x-4y=12, and then once you have it like that you can do the math to find the y and x intercepts.

Solve the following equation for x: 6(4x+50)=3(x+8)+3 round to the nearest hundredth
nalin [4]

Answer:

x = -13

Step-by-step explanation:

6(4x + 50) = 3(x+8) + 3

24x + 300 = 3x + 24 + 3

21x + 300 = 27

21x = -273

x = -13
