FInd the area of the parallelogram. 14.3 cm. 12 cm. 18.4 cm.

Answers

You didn’t state which one of these numbers is the base and the height which is needed to solve this problem.

If 14.3 is the base, and 12 is the height, then you multiply them and get the answer.
14.3 x 12 = 171.6

If 14.3 is the base and 18.4 is the height, multiply them.
14.3 x 18.4 = 263.12

So depending on which one is the base, or the height, the answer would be one of those two.

For your understanding of problems like this, the formula for solving the area of a parallelogram is base times the height.

Hope this helped :)

Find the surface area of the triangular prism (above) using its net (below).

Answers

This is quite simple, first, you must find the area of each shape, since the form of the prism is currently 2D.

Formula for (Area of Rectangle)= length x width

Formula for (Area of Triangle)= 1/2 base x height

Now, we have the formulas. Let’s get started!

(Identification) There are 3 rectangles and 2 triangles. 2 rectangles are of the same size and 2 triangles are of the same size.

Triangles~ the base is 6 and the height is 4.

1/2 (6 x 4) = 12

However, there’s two triangles. (of the same size)

12 x 2 = 24

Rectangles 1 and 2~ the length is 5 and the width is 7

5 x 7 = 35

However, there’s two rectangles. (of the same size)

35 x 2 = 70

Rectangle 3~ the length is 6 and the width is 7

6 x 7 = 42

There’s only one of these.

Now we add all the areas of the shapes together!

24 + 70 + 42 = 136

The surface area is 136.

Hope this helps! ;-)

~Master Chief

Let's solve this problem step by step:

So we know that Isaac sold 'x' number of tubs of dough

⇒ and that each tub of dough is worth 15 dollars

⇒ means he made '[tex]15*x'[/tex] dollars from selling 'x' tubs of dough

⇒ coincidently, we know that he made a total of $165

⇒ So the equation is: [tex]15x = 165[/tex]

Answer: 15x = 165

Base x height = area

12 x 4 = 48

27. Find a polar equation of the conic with focus at the pole that has the given eccentricity and equation of directrix.
e=\frac{4}{3}, r \cos \theta=-3

Answers

The polar equation will be [tex]r=\dfrac{4}{1+cos\theta}[/tex]

What is the polar equation?

A polar equation is any equation that expresses the relationship between r and theta, where r is the distance between the pole (origin) and a point on a curve, and theta is the counterclockwise angle formed by a point on a curve, the pole, and the positive x-axis.

From the equation, we are told that

The Eccentricity: e = 1

The Directrix is y = 4

Generally, the polar equation for e = 1 and y = + c is mathematically represented as

[tex]r =\dfrac{e\times c}{1+ecos\theta}[/tex]

[tex]r =\dfrac{1\times 4}{1+1\times cos\theta}[/tex]

[tex]r=\dfrac{4}{1+cos\theta}[/tex]

Therefore the polar equation will be [tex]r=\dfrac{4}{1+cos\theta}[/tex]

the shoes department is offering a sale of 15% off all shoes. if mrs. jefferey saved $12.30, how much were the shoes full price?

Answers

Answer: $82

Step-by-step explanation:

F - .15F = 12.30

F = 12.3/.85 =$14.47 for full shoe price rounded down a fraction of a cent

Full Price minus 15% discount = $12.30

F - 0.15F = 12.30

F(1-0.15) = 12.30

0.85F = 12.30

Overall answer --->F = 12.30/.85 = 14.47058824

Ricardo paid for 3 pounds of oranges with a $10 bill. He got back $8.20. What was the cost of 1 pound of oranges?

Answers

Answer:

6 cents

Step-by-step explanation:

10 - 8.20 = 1.8

1.8 / 3 = 0.6

Hope this helps you :D

Answer: $0.60

Step-by-step explanation:

Facts

got 3 lbs of oranges

paid with $10, got 8.20 in change.

Step 1: Find how much the 3lbs of oranges actually cost (actual total)

10-8.20= 1.8

Step 2: Find the unit rate (cost per lb)

Cost per lb. Divide the cost by the number of pounds, as shown:

1.8/3= 0.6

Step 3: Checks

[hypothetically], each pound costs 0.60.

Buying 3 pounds of oranges, multiply 0.6x3= 1.8.

Now, you pay with $10.

To find how much change you get, subtract 10-1.8= 8.20

These computations are correct, and the resulting facts match those given in the question. This is how I double check the answer is accurate.

Hence, each pound costs $0.60, or 60 cents.

Hope this helps :)) brainiest would be appreciated :D

HELP PLEASE GIVING 30 POINTS

Answers

Answer:

the ladder is 5 ft from the base of the wall.

To find the unknown length, we need to use the Pythagorean Theorem

The Pythagorean Theorem is a²+b²=c²

Since the legs are x and 12 this means that a=x and b=12

Also, since the hypotenuse is 13, this means that c=13.

Plug in a=x, b=12, c=13x²+12²=13²x²+144=169

Subtract 144 from both sides.

x²=169-144

Combine like terms.

x²=25

Take the square root of both sides.

x=√25

x=5 Simplify the square root.

Answer:

So the solution is x=5 which means that the foot of the ladder is 5 ft from the base of the wall.
