### Answers

**Answer:**

≈ 12.6

**Step-by-step explanation:**

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the third side, then

x² + 6² = 14²

x² + 36 = 196 ( subtract 36 from both sides )

x² = 160 ( take the square root of both sides )

x = [tex]\sqrt{160}[/tex] ≈ 12.6 ( to the nearest tenth )

Mary bought 5 pairs of gloves and 2 hats for $95. Mary received a text from her friend Joanna ask her to buy 4 pairs of gloves and a hat. Mary told Joanna that the cost was $70. How much does each pair of gloves cost? How much does the hat cost?

### Answers

**Answer: **Each pair of gloves costs $15 and each pair of hat costs $10.

**Step-by-step explanation:**

Let x = Cost per pair of gloves

y= Cost per hat.

As per given, we have

[tex]5x+2y=95 \ \ \ \ (i)\\4x+y=70\ \ \ \ \ (ii)[/tex]

Multiply (ii) by 2 , we get

[tex]8x+2y=140\ \ \ \ (iv)[/tex]

Eliminate (i) from (iv), we get

[tex]3x=45\\x=15[/tex]

Put this in (ii), we get

[tex]4(15)+y=70\\60+y=70\\y=10[/tex]

Hence, **each pair of gloves costs $15 and each pair of hat costs $10.**

What are the six trigonometric ratios?

**Trigonometric ratios **for a** right-angled triangle **are from the perspective of a particular **non-right angle.**

In a **right-angled triangle**, two such **angles **are there which are not right **angled**(not of 90 degrees).

The **slanted **side is called the **hypotenuse**.

From the considered **angle**, the side **opposite **to it is called **perpendicular**, and the remaining side will be called the **base**.

The given **function **is f(x)= asin(b(x-h)) where we have to find the **value **of a , b and h.

f(x)= sin 2x – 3 cos 2x

If we **substitute **the value of a, b and h then we get the same **solution **for both the **equation**.

a = 3.16

b = 2

h = 0.62

Thus, option B is the **correct **match for the **values**.

So, let the diameter of this circle be x.

Which means :

Actually Welcome to the Concept of the Functions.

Since, the above function is a square root function, we must always keep it's domain as Positive Real numbers, such that it will not went to the imaginary axis, hence

D: R+

Range, for range we equate it to 0 ,

hence we get as,

R: x belong from 0 to positive Infinite

As, x---> infinite, f(x) ---> - infinite

As, x----> 0 , f(x) -----> 0

increasing interval, we have to differentiate it, we get as

Decreasing interval is 0 to infinite

Greg studied for 12 minutes. This is 40% of the time he wants to study today. How many more minutes does Greg need to study today?

### Answers

**Answer:**

18 More Minutes

**Step-by-step explanation:**

Hi,

I think I can help.

What I would first do here is try to find the value of 10% relative to the 12 minutes. If we find what 10% is we can multiply that to get 100% to find the total amount of minutes he wants to study. We can then subtract the time already studied to find our answer.

To do this we want to take the 40% we have and find 10. We can do 40/4 to find this since 40 divided by 4 is actually 10.

But if we do this we also have to do with to the number it is relating to / representing. Which is 12. (12 minutes = 40%)

So we can do :

40 / 4

=

10%

Also

12 / 4

=

3

So with this we can conclude that 10% of his total time is 3 minutes.

Now lets multiply this by 10 to get the 100% we are looking for so we can get the total amount of time he spent studying.

So :

10% x 10

=

100%

3 x 10

=

30 minutes

So his total time is 30 minutes of studying, but we have to find how many more minutes after his 12.

We can now simply take the total time and take off the time spent already to find this answer :

30 - 12

=

18 minutes

That is your answer, **he needs to study 18 more minutes.**

I hope this helps!

### Answers

I can tell that (448+217+34) x9 is 3 times larger than (448+217+34) x3 because the number inside the equations are being multiplied by 9 which is 3 times bigger than 3 ( the number being multiplied in the 2nd one)(3x3)

find the surface area of the cube below.￼

### Answers

**Answer:**

150

**Step-by-step explanation:**

surface area =6a^2

= 6(5^2)

= 6×25

=150

**Answer:**

150 cm²

**Step-by-step explanation:**

So, firstly we must understand what does total surface area means (T.S.A)

We intuitively know that, it means,

Area of 6 **EQUAL**** ****faces**.

So,

Edge of the cube = 5 cm

Area of **1**** ****face****=**** **5 × 5= 25 cm²

Area of 6 faces= 25 × 6= 150 cm².

So, that means,

T.S.A= 150 Cm²
