Step-by-step explanation:

(a)

3 ft long when divided into half ft each will be

3ft ÷1/2 ft

We change the ÷ to × then the second part is reciprocated hence

3ft÷1/2= 3ft×2/1=6 pieces

(b)

The question requires us to get the differences. Initially, Phil makes 3 quarts of soup but the family takes only half of the original quantity to mean Phil remains with the other half.

Therefore, half of 3 is 3×1/2=3/2= 1.5 or 1 1/2

(c)

Hiding 3 pounds of gold into two equal sections means 3 is divided by 2

3÷2=1.5 or 1 1/2

(d)

If half, 0.5 represent 3 cups then full quantity represent x

0.5=3 cups

1=x

By cross multiplication

1*3/0.5=6

To find the volume of a prism, you multiply the area of its base by its height. Thus, the volume of a prism with a base area of 24 m² and a height of 7 m is 168 m³.

The subject of this question is Mathematics, more specifically, geometry. The question wants to find the volume of a prism. The formula for finding the volume of a prism is Base Area x Height. In this case, the base area of the prism is given as 24 m², and the height is given as 7 m.

We use the formula: Volume = Base Area x Height which translates to Volume = 24 m² x 7 m= 168 m³. So the answer is 168 cubic meters, which corresponds to option A.

Answer:

(1, - 4 )

Step-by-step explanation:

Given the 2 equations

2x - y = 6 → (1)

x + y = - 3 → (2)

Adding the equations term by term will eliminate the term in y, that is

3x = 3 ( divide both sides by 3 )

x = 1

Substitute x = 1 into either of the 2 equations and solve for y

Substituting in (2) gives

1 + y = - 3 ( subtract 1 from both sides )

y = - 4

Solution is (1, - 4 )

Final answer:

By substituting the given values f = 3, g = 2, and h = 7 into the expression f3 + 11g - 4h, and performing the operations as directed, we find that the value of the expression is 3.

Explanation:

To evaluate the expression f3 + 11g - 4h when f = 3, g = 2, and h = 7, we substitute these values into the expression.

Therefore, the value of the expression f3 + 11g - 4h is 3.

Answer:

B and C

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Given the zeros are x = - 1 and x = 3 then the factors are

(x + 1) and (x - 3) and the parabola is the product of the factors, that is

y = a(x + 1)(x - 3) ← where a is a multiplier

To find a substitute (0, - 9) into the equation

- 9 = a(0 + 1)(0 - 3) = a(1)(- 3) = - 3a ( divide both sides by - 3 )

3 = a, thus

y = 3(x + 1)(x - 3) ← expand the factors using FOIL

  = 3(x² - 2x - 3) ← distribute by 3

  = 3x² - 6x - 9 → A

The equation of the parabola has zeros of x = –1 and x = 3 and a y-intercept of (0,–9) is y = 3x² - 6x - 9 . The correct option is A.

An equation of a curve that has a point on it that is equally spaced from a fixed point and a fixed line is referred to as a parabola. The parabola's fixed line and fixed point are together referred to as the directrix and focus, respectively.

Given the zeros are x = - 1 and x = 3 then the factors are (x + 1) and (x - 3) and the parabola is the product of the factors, that is

y = a(x + 1)(x - 3) ← where a is a multiplier

To find a substitute (0, - 9) into the equation.

- 9 = a(0 + 1)(0 - 3)

a(1)(- 3) = - 3a ( divide both sides by - 3 )

3 = a,

y = 3(x + 1)(x - 3)

Expand the factors and calculate.

y = 3(x² - 2x - 3)

y = 3x² - 6x - 9

Therefore, the equation of the parabola has zeros of x = –1 and x = 3 and a y-intercept of (0,–9) is y = 3x² - 6x - 9 . The correct option is A.

Answer:

New altitude = 5.5 miles

Step-by-step explanation:

We are given;

Velocity = 400 m/h

Angle of descent = 1°

Altitude = 7.2 miles

Time = 15 minutes = 15/60 hours = 0.25 hours

Now, the downward component of its speed is;

Vy = (400)sin(1°)

Vy = 6.98 mph

After a time t, its height will be;

h(t) = (7.2 - 6.98t) miles, for t = hours

We are given;t = 0.25 hrs

Thus;

h(0.25) = 7.2 - (6.98*0.25) miles

h(0.25) = 5.46 miles

h(0.25) ≈ 5.5 miles to the nearest tenth

The new altitude after 15 minutes of descent is approximately 5.5 miles.

x=60.25

To get y

Substitute for x in equal one

-5(60.25)-3y=9

-301.25-3y=9

-3y=9+301.25

-3y=310.25

y=-103.4

The solution to the problem 1/2 (10x-2) +3x = 25 is x = 3.25 which is obtained by expanding the equation, combining like terms, isolating the variable, and then solving for the variable.

Let's solve the equation 1/2 (10x-2) +3x = 25 step by step to find the solution to this problem.

Firstly, expand the equation: 1/2 * 10x is 5x, and 1/2 * -2 is -1. Therefore, the equation becomes 5x - 1 + 3x = 25.

Next, combine like terms on the left side of the equation. 5x + 3x is 8x, so you have 8x - 1 = 25.

Then, add 1 on both sides to isolate 8x on the left side. The equation becomes 8x = 26.

Finally, divide both sides by 8 to solve for x. Therefore, x = 26 / 8 = 3.25.

The approximate mean weight for babies born during the two months of August and September is calculated using a weighted average, and it is approximately 7.97 pounds.

Explanation:

To find the mean weight of the babies born during the two months, we can use the weighted average formula which takes into account the different numbers of babies born in each month and their respective mean weights.

The formula for the weighted mean is as follows:

Weighted mean = (Sum of weights × their respective frequencies) / (Total sum of frequencies)

Therefore, the approximate mean weight for the babies born during August and September is 7.97 pounds.

Answer:

The area is 42

Step-by-step explanation:

First you have to divide the figure into three rectangles

The first one has

Lenght=10

Width=5-2=30

Area=l x w=10x30=30

The other two are equivalent in lenght and width that means that if if we find the area of one we must multiply by 2 to find the other.

Rectangles 2 and 3

Lenght=3

Width=2

Area of one of them=3x2=6

Both rectangles=6x2=12

Step-by-step explanation: f(x)= 8x2 + 5=21--> f(x)=21

g(x)= -2x5 - 4=-14--> g(x)=-14

f(2)+g(5) = 7

Step-by-step explanation:

Given,

f(x) = 8x+5

g(x) = -2x-4

To find f(2)+g(5)

Now,

f(2) means putting the value of x = 2 in f(x)

g(5) means putting the value of x = 5 in g(x)

f(2) = 8(2)+5 = 21

g(5) = -2(5)-4 = -14

Hence,

f(2)+g(5) = 21-14 = 7

Answer:

17.6 lbs

Step-by-step explanation:
