Answer:

The coefficient of x is $\frac{1}{3}$

7 is a constant

Step-by-step explanation:

$\frac{x}{3} +7$

We need to find the coefficient of each term in the given expression

x/3 can be written as 1/3 times x

The coefficient is the number with the variable x

The coefficient of x is $\frac{1}{3}$

7 is a constant

Leo has 18 yards of fabric that he wants to cut into pieces that are each 1 foot long. How many one foot long pieces can Leo cre

weqwewe [10]

54 pieces. Here is why:
1 yard = 3 feet
18 yards * (3 feet)/yard = 18*3 feet = 54 feet
Note that the yard units cancel out, leaving the answer in feet.

Chapter : Circles 1 question

erica [24]

We can solve this question in 2 ways: either using degrees or converting the degrees into radians.

Since, the question says degrees itself and there is no specification of using radians only, so I have solved it using degrees itself.

Part (a):

Perimeter of sector ORS = 2*Radius + Arc RS = 2*21 + $60* \frac{ \pi }{180} *21 = \frac{ \pi }{3} *21 = 7 \pi$

Part (b):

Area of sector ORS = $\frac{60}{360} * \pi * 21^{2} = \frac{1}{6} * \pi *21*21= \frac{147}{2} \pi$

Area of sector POQ = $\frac{36}{360} * \pi * 14^{2} = \frac{1}{10} * \pi * 196 = \frac{196}{10} \pi$

Thus, area of shaded region
= Area of sector ORS - Area of sector POQ

= $\frac{147}{2} \pi - \frac{196}{10} \pi = \frac{735 - 196}{10} \pi = \frac{539}{10} \pi = 53.9 \pi$

(17 Leon uses 3/4 cup water to make a serving of iced tea.

Ksivusya [100]

Answer:

A.) 12 3/4 cups

B.) 117 1/3

Step-by-step explanation:

If one serving of ice tea contains 3/4 cup of water, how much does 7 serving have?

To answer this, you must multiply 3/4 and 17

17 is the same as 17/1, so multiply the numerators and denominators

17 x 3 = 51

1 x 4 = 4

51/4 = 12 3/4

So, Leon used 51/4 or 12 3/4 cups of water

If the cooler has 88 servings of tea, how many cups of water does it have?

To solve this, divide 88 by 3/4

Dividing 88 by 3/4 is the same as multiplying 88 by 4/3.

Again, 88 is the same as 88/1 so multiply the numerators and the denominators.

88 x 4 = 352

1 x 3 = 3

352/3 = 117 1/3

So, there are 352/3 or 117 1/3 cups of water in the cooler

I hope this helps!
