Answer:

13% decrease. (13.4193548...% to be specific)

Step-by-step explanation:

The difference is 1550-1342=208. 208 as a percentage of 1550 --> 208/1550= 0.134193548... = 13% to the nearest whole number. So, it is a 13% decrease.

A cone has a diameter of 12 centimeters and a height of 9 centimeters. The volume of the cone would be 2034.72 cubic cm.

Suppose that the radius of considered right circular cone be 'r' units.

And let its height be 'h' units.

Then, its volume is given as:

[tex]V = \dfrac{1}{3} \pi r^3 h \: \rm unit^3[/tex]

The right circular cone is the cone in which the line joining the peak of the cone to the center of the base of the circle is perpendicular to the surface of its base.

A cone has a diameter of 12 centimeters and a height of 9 centimeters.

Radius = 12/2 = 6cm

Height h = 9 cm

The volume of the cone

[tex]V = \dfrac{1}{3} \pi r^3 h \: \rm unit^3[/tex]

[tex]V = \dfrac{1}{3} \times 3.14 \times 6^3 \times 9\: \rm unit^3\\\\V = 3.14 \times 648\\\\V = 2034.72 cm^{3}[/tex]

Hence, The volume of the cone would be 2034.72 cubic cm.

Answer:

To prove : ΔDEC ~ ΔDAB

angle DEC = angle DAB...... ( Corresponding angles when Line EC || Line AB and EC being the transversal)

angle EDC = angle ADB......( Common angle D)

therefore, ΔDEC ~ ΔDAB by A - A test of similarity.

(7)From the diagram

cos 34=y/37

y=37 × cos34

y=30.673 approximately 31

and x+y=52

therefore we have our x=21 and y=31

Answer:

7/24

Step-by-step explanation:

(There are many methods to divide fractions, but this is the easiest one in this situation)

7/6 ÷ 4

Dividing something by four is the same as dividing by 4/1, which is the same as multiplying it by 1/4.

So,

7/6 * 1/4

Multiply the denominators.

7 / 24

Graph D

Step-by-step explanation:

We can look at the number of pounds of pecans and cashews, shown on the x- and y-axis, respectively.

All of the graphs have an x-intercept of (4, 0), meaning that the number of pecans being bought is 4 lbs.

Since pecans cost $6 per lb, we can multiply the cost by 4 in order to make sure that the total cost is not exceeding $24.

Let's look at the y-axis to see how many lbs of cashews Malik can buy. The y-intercept is (0, 3) for all graphs, meaning that 3 lbs of cashews are being bought.

Since cashews cost $8 per pound, we can multiply the cost by 4 in order to make sure that the total cost is not exceeding $24.

The shaded area represents the values that can be used in the problem. Since we want $24 or less, the shaded region has to be below the line.

Malik can spend no more than $24, so the line should be solid since this means that the values the line touches are inclusive. 4 lbs of pecans and 3 lbs of cashews should be inclusive.

The graph that has all of these properties is Graph D.

Answer:

b) BC = 62

Step-by-step explanation:

since AB and AC equal 25, we know that ΔADB ≅ ΔADC and we can write this equation:

3x + 4 = 4x - 5

4 = x - 5

x = 9

3(9) + 4 = 31

BD = 31

DC = 31

BC = 2(31) = 62

Answer:

(n-7) ≤ 95

Step-by-step explanation:

We need to write the expression for the given statement.

Seven less than the product of a number n and  1 means (n-7).

It is no more than 95. No more than 95 means less than or equal to i.e.

(n-7) ≤ 95

Hence, the above inequality shows the given statement.

Answer:

w≥5

Step-by-step explanation:

You just divide 7 by both sides which cancels it on the left, and you get 5 on the other side because 35 divided by 7 is 5.
