Find the area of a parallelogram if a base and corresponding altitude have the indicated lengths. Base 1 1/2 feet, altitude 6 inches. Area = sq. ft. ...?

Answers

Answer 1
Answer: area of a parallelogram = A =base*height

so in this case is just (1½)(6).

first off let's convert the mixed fraction to "improper",

\bf \stackrel{mixed}{1(1)/(2)}\implies \cfrac{1\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{3}{2}} \n\n\n \cfrac{3}{2}\cdot 6\implies \cfrac{18}{2}\implies 9
Answer 2
Answer:

Answer:

3/4 sq. ft.

Step-by-step explanation:

The question is using feet and inches. So, you'd have to convert the 6 inches to feet. How many inches in one foot? 6. So 6=1/2 feet so you do 1 1/2*1/2=3/4

Race car driver mario won 3 races and earned 75 points for each win. During the fourth race he had deductions of 55 points 104 points and 85 points but earned 3 points for finishing. Write and find the value of an expression for how many points he has now

Answers

Answer:

Mario has -16 points.

Step-by-step explanation:

Race car driver Mario won 3 races and earned 75 points for each win.

Total points won = 75*3=225

During the fourth race he had deductions of 55 points 104 points and 85 points but earned 3 points for finishing.

Total points Mario has now = 225+(-55)+(-104)+(-85)+3

= -16 points

Therefore, Mario has -16 points.

Answer:

(75 * 3) + 55 + 104 + 85 + 3.

75 * 3, because each race is 75 points.

How do I find the lateral and total surface area of the prism.Please give a step by step. Thanks.

Answers

Explanation:

Lateral Area

The lateral area is the area of the sides of the prism. If the faces are perpendicular to the bases, then each face is a rectangle. The area of each rectangle is the product of its length and width, generally the product of the height of the prism and the length of one edge of the base.

The total lateral area will then be the product of the height of the prism and the perimeter of the base.

Total Area

The total area is the sum of the lateral area (computed as above) and the area of the two bases of the prism. The formula for that area depends on the shape of the prism. (You have already seen formulas for the areas of triangles, rectangles, and other plane shapes. If not, they are readily available in your text or using a web search.)

a model rocket is fired straight up from the ground. The heigth of the rocket (in feet) at any time T (in seconds) can be modeled by the equation h= -16t^2+ 128 when will the height of the rocket be 240feets from the ground.

Answers

The height is modeled by,

h(t)=-16t^2+128

Where

t is time in seconds

We want to find the time, t, rocket will be 240 feet above the ground.

So we will substitute 240 into h(t) and find the corresponding value of "t".

The steps are shown below:

\begin{gathered} h(t)=-16t^2+128 \n 240=-16t^2+128 \n 16t^2=112 \n t^2=7 \n t=\sqrt[]{7} \end{gathered}

Square root of 7 is approximately 2.65 seconds.

Subtract and write the difference in simplest form 12 5/8 - 7 1/3

Answers

Answer:

5 7/24

Step-by-step explanation:

Given the following mathematical expression;

12 5/8 - 7 1/3

First of all, we would subtract the whole numbers;

12 5/8 - 7 1/3 = (12 - 7) 5/8 - 1/3

12 5/8 - 7 1/3 = 5 [5/8 - 1/3]

Next, we subtract the fractions from each other;

5/8 - 1/3

Lowest common multiple (lcm) = 24

5/8 - 1/3 = (15 - 8)/24

5/8 - 1/3 = 7/24

Combining the two parts, we have;

12 5/8 - 7 1/3 = 5 7/24
