Answer:

Zara = 5
Her Dad = 30

Step-by-step explanation:

Lets say Zara's age is "z"
So, her dad's age must be 6 x z = 6z
As its given that there product is 150 so we can also write it as :

z x 6z = 150
6z to the power 2 = 150
z to the power 2 = 150 divided by 6
= 25
So, z = 5
So Zara's age is 5 so her dad's age must be 30

The combined area of two squares is 45 square centimeter each side of one square is twice as long as the side of another square

Roman55 [17]

Let $x$ be the side length of the small square. Then, the side length of the big square is $2x$ .

The respective areas are $x^2$ and $(2x)^2=4x^2$

So, the sum of the areas are $x^2+4x^2=5x^2$

We have

$5x^2=45 \iff x^2=9 \iff x=\pm 3$

We can't have negative lengts, so we choose $x=3$

So, the side length of the larger square is 6.

17.5% of 120 can be worked out using the following method find 10% of 120=12 then 5% of 120=6 then 2.5% of 120=3. Adding 17.5% o

Answer:

17.5% of 360 = 63

Step-by-step explanation:

We are given a process of finding 17.5% of 120. Following the same process we have to determine the 17.5% of 360.

17.5% can be break down as 10% + 5% + 2.5%

Thus,

STEP 1 : Find 10% of 360 , we get,

$\frac{10}{100} \times 360=36$

STEP 2 : find 5% of 360, we get,

$\frac{5}{100} \times 360=18$

STEP 3: find 2.5% of 360 , we get,

$\frac{2.5}{100} \times 360=9$

STEP 4: 17.5% of 360 = 10% of 360 + 5% of 360 + 2.5% of 360

⇒ 17.5% of 360 = 36 + 18 + 9

⇒ 17.5% of 360 = 63

What is the leading coefficient of the polynomial x^5-198x+5x^12+4-2x^6 and explain why please

forsale [732]

The given expression is

$x^5-198x+5x^{12}+4-2x^6$

And we can also write it as

$5x^{12}-2x^6+x^5 -198x+4$

Leading coefficient is the number or the constant that is with the term with the degree. And here degree is 12, and the constant or the number that is with the term is 5 .

So the leading coefficient is 5 here.
