2/7 = 8/28
1/4 = 7/28
Mr.Pham mowed more by 1/28
15/28 is total, leaving 13/28 left.
Hope this helps! :)

Pham mowed more than his son because you make the denominators equal (2/7 x 8 and 1/4 x 13) then compare them and you'll find your answer and there is another way to multiply the fractions

Given that 1 kilogram weighs approximately 22 pounds, rewrite 10 pounds as an equivalent number of kilograms

yaroslaw [1]

Answer:

0.4545 kgs.

Step-by-step explanation:

Given that 1 kg weighs approximately 22 pounds.

i.e. 1kg= 22 lbs.

We can use this to convert lbs into kg.

22 lbs = 1 kg

Hence 1 lb = 1/22 = 0.04545 kg

Now to find out the equivalent weight for 10lbs,

we have conversion factor as 1 lb= 0.04545 kg

Hence 10 lbs = 10(0.04545) = 0.4545 kgs

Hence 10 pounds written in equivalent kgs would be0.4545 kgs.

Write the expression as the sine or cosine of an angle sin(pi/7) cos(x) + cos(pi/7) sin(x)

Natasha_Volkova [10]

Answer:

$\sin(\frac{\pi}{7}+x)$

Step-by-step explanation:

We are going to use the identity

$\sin(a+b)=\sin(a)\cos(b)+\cos(a)\sin(b)$

because this identities right hand side matches your expression where

$a=\frac{\pi}{7}$ and $b=x$ .

So we have that $\sin(\frac{\pi}{7})\cos(x)+\cos(\frac{\pi}{7})\sin(x)$ is equal to $\sin(\frac{\pi}{7}+x)$ .

How can you simplify this on to an expression

LiRa [457]

Hello :
1/(√6 -1) = (√6 +1)/(√6 -1)(√6 +1) = (√6 +1)/(√6)²-1² ) = (√6 +1)/5

Find length of each side

IgorLugansk [536]

Option b: 10 in, 18.5 in, 31.5 in.

Explanation:

The three sides of a triangle are $2y+1, 3y+5$ and $7y$

The perimeter of the triangle is $60 in$ .

Since, Perimeter = all sides of the triangle

Let us add all the three sides to determine the length of each side.

$Perimeter=2y+1+3y+5+7y$

Substituting the value of Perimeter and simplifying, we get,

$60=12y+6\\54=12y\\4.5=y$

Substituting $y=4.5$ in the three sides of the triangle $2y+1, 3y+5$ and $7y$ , we get,

$2y+1=2(4.5)+1=10 in$

$3y+5=3(4.5)+5=18.5 in$

$7y=7(4.5)=31.5 in$

Thus, the lengths of each side are 10 in, 18.5 in, 31.5 in.

Find the geometric mean of four and 10

lawyer [7]

The Geometric mean of 4 and 10 is 6.32

<u>Explanation:</u>

Given:

Two numbers are 4 and 10

Geometric mean, GM = ?

We know,

GM = $\sqrt[n]{a_1 X a_2}$

Where,

n = 2

Substituting the value we get"

$GM = \sqrt[2]{4 X 10} \\\\GM = \sqrt[2]{40} \\\\GM = 6.32$

Thus, the Geometric mean of 4 and 10 is 6.32
