7 flower bunches

Step-by-step explanation:

One flower bunch requires 12 roses since 48/4 is 12

then to find out how many flower bunches can be made by 84 roses you would have to divide 84 by 12 which gives you 7.

Answer:

7

Step-by-step explanation:

48 roses divided by 4 roses is 12 roses per bunch.

84/12=7

Metric Unit: US Standard Unit (English Unit or Customary Unit) Millimeter (mm) Used to measure very short lengths or thicknesses. Example, length of a pencil tip. Centimeter (cm): Used to measure small lengths. Example: Length of a pencil. Meter (m): Used to measure big lengths. Example: Length of a classroom. Kilometer (km):

Step-by-step explanation:

Answer:

C.

Step-by-step explanation:

A box of tissues is not that big, so we can't use kilometers.

You are only measuring the length, not the weight, so we can't use grams or kilograms.

The only option left is C, centimeters.

Answer:

  x + 2.6 = 10.4

  x = 7.8

Step-by-step explanation:

If 2.6 liters are added to x liters with the result that 10.4 liters then exist, the model is ...

  2.6 +x = 10.4 . . . . . . . 2.6 added to x gives 10.4

The commutative property of addition lets you rewrite this to ...

  x +2.6 = 10.4

__

Subtracting 2.6 from both sides of the equation gives its solution:

  x +2.6 -2.6 = 10.4 -2.6

  x = 7.8

Step-by-step explanation:

cube surface area = 6 x 9 x 9 = 486 in²

The area of the region is -2/3 square units

Since the region is bounded on the left by x = y²/2 and on the right by x = 3y - 4 for 2 ≤ y ≤ 4, the area of the region is given by

[tex]A = \int\limits^4_2 {\frac{y^{2}}{2} } \, dy - \int\limits^4_2 {(3y - 4)} \, dy \\[/tex]

Integrating, we have

A = [y³/6]₂⁴ - [3y²/2 - 4y]₂⁴

A = [4³/6 - 2³/6] - [3(4)²/2 - 4(4) - {3(2)²/2 - 4(2)]}]

A = [64/6 - 8/6] - [3(16)/2 - 16 - {3(4)/2 - 8]}]

A = [64/6 - 8/6] - [3(16)/2 - 16 - {3(4)/2 - 8]}]

A = [64/6 - 8/6] - [3(8) - 16 - {3(2) - 8]}]

A = [(64 - 8)/6] - [3(8) - 16 - {3(2) - 8]}]

A = [56/6] - [24 - 16 - {6 - 8}]

A = [56/6] - [8 - {-2}]

A = [56/6] - [8 + 2]

A = [56/6] - [10]

A = 56/6 - 10

Taking the L.C.M, we have

A = (56 - 10 × 6)/6

A = (56 - 60)/6

A = -4/6

A = -2/3 square units

So, the area of the region is -2/3 square units

Answer:

94a - 32b - 72c + 560

Step-by-step explanation:

First get the product of 6(3a + 12b - 4c) = 18a + 72b - 24c.

Second get the sum of 14a + 70 and 5b - 12c = 14a + 5b - 12c + 70 then multiply by 8 and the product is 112a + 40b - 96c + 560. Subtract the first product from the 2nd product to get the final answer

[tex]44:20[/tex]

Cancel common factor : 4

[tex]44 \div 4 = 11 \\ 20 \div 4 = 5 \\ 11:5[/tex]

The ratios are 44:20=11:5

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

The given ratios are  44:20 = ?:5

we have to find the number in question mark place.

Let question mark be taken as x.

The ratios can be written in the form of fraction

44/20=x/5

Apply cross multiplication

44×5=20x

220=20x

Divide both sides by 20

x=220/20

x=11

Hence, the ratios are 44:20=11:5

The probability model shows the distribution of people of age 20 to 39 years

The value of the probability P(A) is 0.631

From the question, the notation P(A) represents the probability that a person is either 20-24 years old or is married

From the table, we have the following parameters:

The probability, P(A) is then calculated as:

P(A) = P(20-24) + P(Married) - P(20-24 and Married)

Substitute known values

P(A) = 0.26 + 0.398 - 0.027

Evaluate the expression

P(A) = 0.631

Hence, the value of the probability P(A) is 0.631

Answer:

the person above me is correct!

Step-by-step explanation:

The change in the current price of the bond when the market interest rates increase from 5% to 5.5% is a fall in the price of the bond.

The attractiveness of bonds occurs when the interest rates fall.  This fall drives up demand for bonds with fixed interest rates and the increasing demand causes bond prices to rise.

This implies that when interest rates rise, investors do not prefer the lower fixed interest rate paid by a bond.  The reduced demand for bonds results in their declining prices.

Thus, when interest rates rise, bond prices fall and when interest rates fall, bond prices rise.
