if a=2,b=-1,c=-3 and d=-2.find the value of 7a2-3ac+d2
Answer:
42
Step-by-step explanation:
It's just a distribution property where the given value of each variables (a, b, c, d) are being distributed to the given equation:
7a2-3ac+d2
7(2)(2) - 3(2)(-3) + (-2)(2)
28 + 18 - 4 = 42
A cone has a diameter of 12 centimeters and a height of 9 centimeters. Using 3.14 for pi, find the
volume of the cone to the nearest tenth.
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.
How to find the volume of a right circular cone?
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.

3x + 4
D 4x - 5 c
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:
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

Malik can spend no more that $24 to buy pecans and cashews. He will spend $6 per
pound for pecans and $8 per pound for cashews. Which graph represents the number
of pounds of pecans and the number of pounds of cashews Malik can buy?
Answer:
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.
$6 · 4 lbs = $24Let'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.
$8 · 3 lbs = $24The 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.
