Step-by-step explanation:

Blake bought a new car. He borrowed $12,500 from the bank. After 4 years he had paid off the loan and paid $1500 in interest. What rate did he borrow at?

This is a simple interest question

The formula to find the rate is given as:

Equation:

r = (1/t)(A/P - 1)

t = time = 4 years

P = Principal = $12500

I = Simple Interest = $1500

A = Total Amount = Principal + Simple Interest = $12500 + $1500

= $14000

Calculation:

Solving our equation:

r = (1/4)((14000/12500) - 1) = 0.03

r = 0.03

Converting r decimal to R a percentage

R = 0.03 * 100 = 3%/year

there are 10  different combinations of pairs of colors.

Combinations are ways to choose elements from a collection in mathematics where the order of the selection is irrelevant. Let's say we have a trio of numbers: P, Q, and R. Then, combination determines how many ways we can choose two numbers from each group.

Given, Loris has one of each of the following colors of felt-tip pen in her pencil case: red (R) blue (B) yellow (Y) green (G) purple (P) She pulls out two random pens.

from the formula of combination;

total combination  ⁿCₓ = [tex]\frac{n!}{(n-r)! * r!}[/tex]

Where, n = total numbers

r = desired number out of total

In our case

n = 5 and r = 2

Thus, the Total combination = ⁵C₂

Total combination = 5! / (3! *2!)

total combination = 5 *4 /2 = 10

therefore, There are ten distinct ways to pair the colors together.

Ooooooooo Proportion question!

We can write an equivalent fraction here:

[tex]\frac{1}{5} =\frac{12}{x}[/tex]

Because 12 wold be equivalent to the 1 inches.

We can multiply by 12 because 1*12 would be 12.

5*12=60.

x=60, which is the answer.

Answer:

b and c

Step-by-step explanation:

the answer is b and c

The triangles ABC and SDC are similar triangles

From the question, we understand points S, C and A are collinear, while line AB and SD are vertical and parallel lines at the either sides of point C.

Hence, Gilligan can conclude that triangles ABC and SDC are similar

To do this, we make use of the following equivalent ratio

[tex]SD : 130 = AB : 23[/tex]

Substitute 90 for AB

[tex]SD : 130 =90 : 23[/tex]

Express as fraction

[tex]\frac{SD}{130} =\frac{90}{ 23}[/tex]

Make SD the subject

[tex]SD =\frac{90}{ 23} * 130[/tex]

[tex]SD =509[/tex]

Hence, Gilligan can conclude that the distance of the ship from the shore is 509 ft

Answer: Choice C

[tex]x < -2 \ \text{ or } \ x \ge 4[/tex]

========================================================

Explanation:

The blue portion on the left is represented by [tex]x < -2[/tex] as it describes values smaller than -2. Notice the open hole at -2 which indicates we do not include this value. So that's why we go with [tex]x < -2[/tex] instead of [tex]x \le -2[/tex]

The blue portion on the right is represented as [tex]x \ge 4[/tex] describing values that are equal to 4, or larger than 4.

So overall, the entire graph visually represents x values such that [tex]x < -2 \ \text{ or } \ x \ge 4[/tex]

Side note: the "or" means we pick one region or the other, but not both regions at the same time.

Answer:

1200 ounces

Step-by-step explanation:

How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?

Let us represent

Number of ounce of 10% copper = x

Hence, our Equation =

x × 10% + 600 × 70% = (x + 600) × 30%

0.1x + 420 = (x + 600)0.3

0.1x + 420 = 0.3x + 180

Collect like terms

0.3x - 0.1x = 420 - 180

0.2x = 240

x = 240/0.2

x = 1200 ounces

Answer:

width = 40 cm

Step-by-step explanation:

Since the pentagons are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{4x}{x}[/tex] = [tex]\frac{48}{x+2}[/tex] ( cross- multiply )

4x(x + 2) = 48x ← distribute left side

4x² + 8x = 48x ( subtract 48x from both sides )

4x² - 40x = 0 ← factor out 4x from each term on left side

4x(x - 10) = 0

Equate each factor to zero and solve for x

4x = 0 ⇒ x = 0

x - 10 = 0 ⇒ x = 10

However, x > 0 then x = 10

Thus width = 4x = 4 × 10 = 40 cm

Answer: B.) vertex

Step-by-step explanation:

On a parabola, the extreme point (which is the highest, lowest, or farthest point left or right) is called the ''Vertex.''

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

To find the extreme point of the parabola.

Now, We know that;

Every parabola has a shape of an U,

Then, they have an extreme point. Depending if the parabola has the formula y = ax² + bx + c or x = ay² + by + c (where a, b and c are constants) and what value constant a has, what kind of extreme point the parabola have.  

Hence, On a parabola, the extreme point (which is the highest, lowest, or farthest point left or right) is called the ''Vertex.''
