Answer:

5

Step-by-step explanation:

We need to find an expression for the calculation, divide 10 in half and subtract from 50 divided into fifths .

The statement '' divide 10 into half '' means we need to divide 10 by 2, such that we get \frac{10}{2}=5 (i)

The statement '' 50 divided into fifths '' means we need to divide 50 by 5 i.e,\frac{50}{5}=10 (ii)

According to question, on subtracting (i) from (ii), we get \frac{50}{5}-\frac{10}{2}=10-5=5

Find the missing side of the triangle
Oksana_A [137]

Answer:

x = 2\sqrt{5}

Step-by-step explanation:

2² + 4² = x²

4 + 16 = x²

\sqrt{x^2} = \sqrt{20}

x = \sqrt{2^2} × \sqrt{5}

x = 2\sqrt{5}

The height of a rectangular prism is 3 feet. The length and width can be expressed as x-1 and x+4. If the volume of the prism is
SashulF [63]

Answer:

Step-by-step explanation:

Volume  = 198 ft

length * width * height = 198

(x - 1) * (x + 4) * 3 = 198

(x - 1) * (x + 4)  = 198/3

(x - 1) * (x + 4) = 66

x*x + x*4 -1*x - 1*4 = 66   {Use FOIL method to multiply}

x² + 4x - x - 4 = 66

x² + 3x - 4 =66

x² + 3x - 4 - 66 = 0

x² + 3x - 70 = 0

Now factorize.

x² + 10x - 7x - 7*10 = 0

x(x +10) - 7(x + 10 ) = 0

(x + 10)(x - 7) = 0

x - 7 = 0 {x + 10 is ignored because measurement cannot be in negative}

x = 7

length = x - 1 = 7 - 1 = 6ft

Width = x + 4 = 7 + 4 = 11 ft

Please help with this!!! Im so confused, I will mark brainliest if right!! Explain
devlian [24]

Answer: Yes these triangles are similar

Step-by-step explanation:

First lets write down what we know just to make life easier

x=9

TL should be similar to CH

LY should be similar to KH

The angles should be equal due to SAS

So the first thing we know is true is the fact that they have equal angles. Now we have to find out if the sides are similar or if they change by the same ratio to the other. If TL is similar to CH and TL=25  and CH=10 what is the change in size or dilation. Division should do the trick so 25/10=2.5 so TY is greater than CH by a factor of 10. Which means that LY should also be greater than KH by a factor of 2.5. If we are told that x=9 than side LY or 4(9)-1=35 and KH 9+5=14

So side KH is 14 and LY is 35. Now to check if they are similar then KH should be greater by a factor of 2.5. If this is not true than the sides are not similar.  35/2.5=14

Since 35 divided by 2.5 is 14 we can tell both sides TL and LY are greater than KH and CH by a factor of 2.5

Hope this helps.
