Step-by-step explanation:

volume = 176 cm³

height = 7.8

radius = ?

pi = 3.14

volume of cylinder = πr²h

176 = 3.14 × r² × 7.8

176 = 24.492 × r²

176/24.4 = r²

7.21 = r²

√7.21 = r². ( Using long division )

r = 2.69 ( approx. )

The expression to represent the amount of money Dion spent on fruit is 3x + 2y.

The amount of money Dion spent is $6.15

Expression are numbers, symbols and operators grouped together that show the value of something.

Dion bought 3 pounds of oranges and 2 pounds of grapefruit.

The expression to represents the amount of money Dion spent on fruit is as follows:

let

x = cost of each pounds of oranges

y = cost of each pounds of grapefruit

Therefore,

total cost = 3x + 2y

Let's evaluate the expression

total cost = 3(0.99) + 2(1.59)

total cost = 2.97 + 3.18

total cost = 6.15 dollars

Therefore, Dion spent $6.15

Answer:

S = R θ      where θ is in radians

If θ  = 2 pi then S = 2 pi R       the circumference of the circle

θ = S / R = 9.7 / 9 = 1.08 rad

Since 1 rad = 360 / (2 pi) = 57.3 deg

the angle included = 1.08 rad * 57.3 deg/rad = 61.9 deg

Answer:

x = - 3, y = - 1

Step-by-step explanation:

y = 7x + 20 -----> equation 1

4x - y = - 11

4x - ( 7x + 20 ) = - 11

4x - 7x - 20 = - 11

- 3x = - 11 + 20

- 3x = 9

x = 9 / - 3

x = - 3

Substitute x = - 3 in equation 1,

y = 7 ( - 3 ) + 20

  = - 21 + 20

y = - 1

Hence,

x = - 3

y = - 1

Answer:

Explanation:

y = 7x + 20 __ equation 1

4x - y = -11

y = 11 + 4x __ equation 2

using substitution method,

11 + 4x = 7x + 20

4x - 7x = 20 - 11

-3x = 9

x = -3

Find y,

y = 7x + 20

y = 7(-3) + 20

y = -1

Answer:

x = 4

Step-by-step explanation:

3x - 2y = 6 → (1)

x + 2y = 10 → (2)

add (1 ) and (2) term by term to eliminate y

(3x + x) + (- 2y + 2y) = 6 + 10 , that is

4x = 16 ( divide both sides by 4 )

x = 4

Answer:

4.8 ounces

Step-by-step explanation:

X= number of ounces for the $3.00 mixture of seasoning

$3.00/OZ + $1.75/ OZ = $2.00/ OZ We are adding the seasonings together to produce the 24 OZ mixture

X + 24-X = 24OZ To get the missing term we will subtract what we have from X

100 [(3.00)(X) + (1.75)(24-X)] = [(2.00)(24)] 100 to get rid of the decimals multiply both sides by 100

(300)(X) + (175)(24-X) = (200)(24) Multiply on each side, removing the parenthesis

300X + 4,200 - 175x = 4,800 Get all of the X's on one side of the equation remember to change the sign of 4,200

300X - 175X = 4,800 - 4,200 Combine Like Terms

125X = 600 Get X alone

125 125 To get X, we will divide both sides by 125

X = 4.8 OZ

The chef used 4.8 ounces of the $3.00 seasoning

Answer:

Part A: (4x+3) (4x+3)

Part B: 4 (x+y) (x-y)

(If this is not the answer you are looking for, sorry)

Step-by-step explanation:

Part A: (16x²+24x+9)

FOIL

(4x + 3) (4x +3) = 16x²+24x+9

(4x) (4x) = 16x²

(4x) (3) = 12x

(4x) (3) = 12x

12x + 12x = 24x

(3) (3) = 9

The shopkeeper giving 80% discount on the Christmas tree during the sale.

A discount is an amount that is subtracted from the regular price of an item.

[tex]discount \ percent = \frac{original \ price - final \ price }{original \ price } \times 100[/tex]

According to the given question.

The marked price of the Christmas tree i.e. original price = $364.

The price of the Christmas tree on sale i.e. final price  = $72.80

So,

The discount given on the Christmas tree

= Original price - final price

= $364 - $72.80

= 291.2

Therefore,

Discount percent  = [tex]\frac{291.2}{364} (100)= 80 \ percent[/tex]

Hence, the shopkeeper giving 80% discount on the Christmas tree during the sale.
