Okay so we know that it has to reach at least 10 inches for the school to announce.

We know it has already snowed 1.5 inches.

We want to know how much more it needs to snow to reach 10 inches in order for there to be an announcement.

You can form an equation like this:

1.5+ x= 10
Subtract 1.5 from each side.

X= 8.5

So now we know that we need 8.5 inches more in order for it to reach 10 inches and for there to be an announcement.

lilavasa [31]

Answer:

If you have    

f(x) = x^2

The point  (2,4)   would be transformed to (1,1)

Step-by-step explanation:

If your compression is horizontal then the transformation you are making is the following

g(x)  = f(x/2)

Therefore, if you have    

f(x) = x^2

The point  (2,4)   would be transformed to (1,1)

The rectangles in the figure below are similar. Find the value of x
V125BC [204]

Answer:

C. 6

Step-by-step explanation:

It is given that the rectangles in the figure are similar.

<em>Thus, the corresponding sides of the two rectangles will be equal.</em>

So, we get,

\frac{3}{x}=\frac{5}{x+4}

i.e. 3(x+4)=5x

i.e. 3x+12=5x

i.e. 2x=12

i.e. x = 6.

Hence, the value of x is 6.

AREAS AND VOLUMES OF SIMILAR SOLIDS URGENT?
Llana [10]

Formula for the volume of cone is \frac{1}{3} \pi r^2h

Where r= radius of the cone

h = height of the cone

The value of pi is 3.14

Given volume of larger cone is 131 cm^3

Volume of larger cone = \frac{1}{3} \pi r^2h

131 = \frac{1}{3} \pi 5^2h

Solve for h

131 = 26.1667 *h

So h= 5 cm

The height of bigger cone = 5cm

Now we find the volume of smaller cone

Two cones similar so the sides are in proportional

\frac{radius(small)}{radius(large)}=  \frac{height(small)}{height(large)}

\frac{2}{5} =\frac{ height of small}{5}

Height of smaller cone = 2cm

volume of smaller cone = \frac{1}{3} \pi 2^2*2

= 8.38cm^3

total of 78 baseball and football cards in a box. ratio of baseball to football cards is 8 to 5. how many baseball cards are in
Katen [24]
The best way to work this to add the two numbers of the ratio together (8+5), giving you 13. You should then divide the total number of cards (78), by this, giving you 6. This means that each part of the ratio is worth 6. The first ratio is 8, meaning that you will have 6x8 baseball cards. There will be 48 baseball cards. The second ratio is 5, meaning that you will have 6x5 football cards. There will be 30 football cards.
In the box, there are 48 baseball cards
