Juanita borrowed $600 to purchase a new computer. She was charged 7% interest for two years. She used the simple interest formula to find the interest.
I = 600(7)(2)
What error did Juanita make and how will her error affect the interest she calculates? Explain

Answers

Answer 1
First, you would write 7% as a fraction, 7/100. Then, you would write 600 as a fraction. Let's make x  the interest Juanita has to pay. The fraction would be x/600. If we have 7/100 interest, you would put that 7/100 = x/600. The next step is to cross multiply. That is 7 times 600 and 100 times x. You would get 4200 and 100x. In order to find x, you have to get rid of the 100, and to do that you have to divide both sides by 100. Remember, what you do to one side, do to the other. That leaves you with 4200/100 and 100x/100. The result is 42 and x, so x = 42. Juanita has to pay $42 interest.

Last year 950 people attended a town's annual parade. This year 1,520 people attended. What was the percent increase in attendance from last year's to this year?

There was a 60% increase in attendance. 

Original #: 950

how many 2/3 cup servings are in a 4 cup container of food

Answers

Final answer:

To find out how many 2/3 cup servings are in a 4 cup container, divide 4 by 2/3, resulting in 6 servings.

Explanation:

The question is about determining how many 2/3 cup servings are in a 4 cup container of food. To find the answer, you divide the total amount of the container by the serving size. So, you divide 4 cups by 2/3 cup.

Calculation:

1 cup / (2/3 cup) = 3/2 servings

4 cups * (3/2 servings) = 6 servings

Therefore, you can fit 6 servings of 2/3 cup each in a 4 cup container.

A rectangle is 15 cm long. Find the area and perimeter of the rectangle if it's width is 3/5 of the length

Answers

The length is 15 cm.  The width is 3/5 of that.
15/5 = 3
3 x 3= 9. 9 cm is the width.
Perimeter: 15(2) + 9(2) = 48 cm
Area: 15(9) = 135 cm

The area of the rectangle is 135 [tex]cm^{2}[/tex], and the perimeter is 48 cm, given that the width is 3 / 5 of the rectangle's length which is 15 cm.

To find the area and perimeter of a rectangle where the width is 3/5 of the length, we apply the formulas. First, calculate the width:

Width = 3 / 5 × Length

Width = 3 / 5 × 15

Width = 9 cm

Now, calculate the area:

Area = Length × Width

Area = 15 cm × 9 cm

Area = 135 cm²

Next, calculate the perimeter:

Perimeter = 2 x (Length + Width)

Perimeter = 2 x (15 cm + 9 cm) = 2 x (24 cm)

Perimeter = 48 cm

The area of the rectangle is 135 cm2, and the perimeter is 48 cm.

Two similar vases have heights which are in the ratio 3 : 2.
(a) The volume of the larger vase is 1080 cm cube. Calculate the volume of the smaller vase.
(b) The surface area of the smaller vase is 252cm square. Calculate the surface area of the larger vase.

Answers

Answer:

a). Volume of the smaller vase = 320 cm³

b). Surface area of the larger vase = 567 cm²

Step-by-step explanation:

When we calculate the volume of any figure we multiply it's three dimensions either length, width, height or we do the cube of the radius (r×r×r=r³).

In other words volume is a three dimensional figure and surface area is two dimensional.

Therefore, ratio of volumes of two similar structures will be the ratio of cube of one side given.

a). [tex]\frac{V_{1}}{V_{2} }=(\frac{Side 1}{Side2})^{3}[/tex]

[tex]\frac{V_{1}}{V_{2} }=(\frac{3}{2})^{3}[/tex]

[tex]\frac{1080}{V_{2} }=(\frac{3}{2})^{3}[/tex]

[tex]\frac{1080}{V_{2} }=(\frac{27}{8})[/tex]

[tex]27V_{2}=8\times 1080[/tex]

[tex]V_{2}=\frac{8640}{27}[/tex]

[tex]V_{2}=320[/tex] cm³

b). Similarly ratio of the surface area of two vase will be

[tex]\frac{A_{1}}{A_{2} }=(\frac{Side 1}{Side2})^{2}[/tex]

[tex]\frac{A_{1}}{252}=(\frac{3}{2})^{2}[/tex]

[tex]\frac{A_{1}}{252}=(\frac{9}{4})[/tex]

[tex]A_{1}=\frac{9\times 252}{4}[/tex]

[tex]A_{1}=567[/tex] cm²

A sail on a sailboat is a triangle with two sides perpendicular and each side is a different length. What are the two terms that could be used to describe the sail?

Answers

you could say that the triangle is a scalene triangle because all sides are different lengths and you could say that it is a right triangle because of the perpendicular lines, which form a right angle

Base of the Sail is 12 feet and Height of the Sail is 5 feet

What is Right Angle Triangle?

A right triangle or right-angled triangle, or more technically an orthogonal triangle, historically known as a rectangled triangle, is a triangle with one right angle (that is, a 90-degree angle) and two perpendicular sides. Trigonometry is founded on the relationship between the sides and other angles of a right triangle.

here, we have,

Solution:

According to the Question,

Let, Base = x and Height = y

x = 7 + y

Using the Pythagorous Theorem

a^2 + b^2 = c^2

Using the above mentioned relation

49 + y^2 + 14y + y^2 = 169

2y^2 + 14y - 120 = 0

Discriminant = 34

y = 5, -12

The length of a sail can not be negative, therefore y = 5

From the equation 1, x = 12

I don't understand slope intercept or how to calculate it. Can you simplify it for me being as specific as possible? What do I do?

Answers

The slope intercept form is written in the form y = mx + b
Where m is the slope and b is the y intercept. 
The reason why it's called slope intercept form is because it's very easy to see the slope (m) and the y intercept (b).

To calculate the slope intercept form, we just plug in some values for x.

Say we have this equation: y = 2x + 3
We see that the slope is 2 and the y intercept is 3.

Plug in some values for x. I'll do 0.

y = 2(0) + 3
The 2 cancels out and we are left 3!

y = 3

We see when x is equal to 0, we get the y intercept.

So, we have the point (0,3). We need at least two points in order to graph a line.

Let's plug in another value. Let's do 1.

y = 2(1) + 3

y = 2 + 3

y = 5

We now have the points (0,3) and (1,5). Just run a line through it to graph it.

Here is a picture I put below to help you.

Sorry if the line isn't exactly straight. It was kinda of hard to draw it.

That line represents the formula y = 2x + 3

Answers

680-130=550 550 / 50=11 They each must pay $11
So you take 680 - 130 to find how much the club members in total will need to raise ~ 680 - 130 = 550

Then you take 550 divided by the number of members, 50, to find how much each person needs to raise ~ 550 / 50 = 11

So each member of the chess club will need to raise $11

Final answer:

To find 5/6 of 15, multiply 5/6 by 15/1 to get 75/6, which simplifies to 25/2 or 12.5 in decimal form.

Explanation:

To find 5/6 of 15, we can approach the problem in a straightforward manner by multiplying 5/6 by 15. Here are the steps to do this:

First, express the number 15 as a fraction by putting it over 1, so it becomes 15/1.Next, multiply the numerators (top numbers) of the fractions together: 5 times 15 equals 75.Then, multiply the denominators (bottom numbers) of the fractions together: 6 times 1 equals 6.The result of multiplication gives you 75/6.Now, to simplify the fraction, divide both the numerator and the denominator by their greatest common divisor, which in this case is 3.75 divided by 3 equals 25, and 6 divided by 3 equals 2.Therefore, the simplified result is 25/2, which is the same as 12.5 when expressed as a decimal.

The answer in simplest form is 25/2 or 12.5.
