Mathematics

Answer:

A = 14 units ²

Step-by-step explanation:

Hello There!

The polygon shown is a triangle

The first step is to find the formula for area of a triangle

A=\frac{1}{2} bh

where b = base and h = height

the following dimensions are given

base = 7 and 4 = height

so all we have to do is plug in the values into the formula

A=\frac{1}{2} 7*4\\7*4=28\\\frac{1}{2} 28=14\\A=14

so we can conclude that the area of the polygon is 14 units ²

A typical credit card company charges 18% annual interest,
AnnZ [28]

Answer:

$1,519

Step-by-step explanation:

Given that :

Balance = principal = $520

Time (t) = 6 years

Annual. Interest rate (r) = 18% = 0.18

Using the compound interest formula:

A = P(1 + r/n)^nt

n = number of times interest is applied per period ; A = final amount

Since interest is compounded monthly, n = 12

A = 520(1 + 0.18/12)^(12 * 6)

A = 520(1 + 0.015)^72

A = 520(1.015)^72

A = 520(2.9211579)

A = 1519.0021

Hence, final amount = $1519

Can someone help me with this question

Answer:

  28 square units

Step-by-step explanation:

The figure can be decomposed several ways. Maybe easiest to see is as a 8×4 rectangle with a 2×4 right triangle cut from the corner.

The area of the rectangle is ...

  A = LW = (8)(4) = 32

The area of the missing triangle is ...

  A = 1/2bh = 1/2(2)(4) = 4

Then the area of the shaded figure is ...

  32 - 4 = 28 . . . square units

_____

<em>Alternate solution</em>

If you divide the figure with a horizontal line across the middle, it becomes a 4×4 square and a trapezoid with bases 2 and 4 and height 4. The shaded area is the sum of these areas.

The area of a trapezoid is ...

  A = 1/2(b1 +b2)h

  A = (1/2)(2 +4)(4) = 12

The area of the square is ...

  A = s² = 4² = 16

Then the total area is ...

  12 +16 = 28 . . . square units

"the distribution of means is the correct comparison distribution when"
alexandr402 [8]

The distribution of means is the correct comparison distribution when

Answer: The distribution of means is the correct comparison distribution when there is more than one person in a sample.

The distribution of the sample means is also called the sampling distribution of mean. It is most appropriate when we take a random sample of size n from the population of size N. The distribution of the sample means will follow normal distribution with mean = \mu and standard deviation = \frac{\sigma}{\sqrt{n}}

Answer:

UV corresponds to RS.

\angle R corresponds to \angle U

Step-by-step explanation:

Given

\triangle SRQ and \triangle VUT

Transformation: Rigid

Required

Determine the true options

When a rigid transformation occurs from SRQ to VUT, the following are the corresponding sides:

SR to VU, SQ to VT, RQ to UT

And the corresponding angles are:

<S to <V, <R to <U and <Q to <T

From the corresponding sides above, we have:

SR to VU

Rewrite:

RS to UV

Hence: (c) is correct

From the corresponding angles above, we have:

\angle R to \angle U

Hence:

(b) is correct
