Find the measurement indicated in each parallelogram.

Answer:

235.4

Step-by-step explanation:

7% more than 220 would be 235.4

First you would turn 7% as a decimal which would be .07. Then, you would multiply .07 times 220 which would give you 15.4. Lastly, you would add 15.4 plus 220 which would equal 235.4.

7%=.07

.07×220=15.4

15.4+220=235.4

The percentage is 42.8571%.

Percentage, a relative value indicating hundredth parts of any quantity. One percent  is a hundredth part; thus, 100 percent represents the entirety and 200 percent specifies twice the given quantity.

All of something is 100 percent, half of it is fifty percent, none of something is zero percent. To determine a percentage, you divide the portion of the whole by the whole itself and multiply by 100.

Given fraction:

3/7

To convert the fraction into percentage we have multiply 100

3/7*100

=300/7

= 42.8571%

Hence, the percentage of fraction 3/7 is 42.8571%.

The equation to represent the growth of the trees is given by

AA=32+6t and BB=20+9t and both the trees will be of equal height after 3 years.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.

Equation is defined as the quality of being equal and is frequently represented by a mathematical statement with equal values on either side or by a problem requiring consideration of a number of factors.

Given that tree A is 32 inches tall and tree B is 20 inches tall.

Tree A grows 6 inches per year.

Length of the tree A after t years = 32 + 6t

Tree B grows 9 inches per year

Length of the tree B after t years = 20 + 9t

Now let us consider that both trees grows equal after a certain period of time.

If we equate both the expressions then we can form an equation to calculate the value of t.

∴ 32+6t = 20+9t

or, 6t - 9t = 20 - 32

or, -3t = -12

or,  t = 4 years

The trees will be of equal length after 4 years.

The value of n which is a constant representing number of innings is equal to 50.

What is ERA or earned run average ?

Earned runs without the help of passed ball, are represented by the earned run average, which is the number of earned runs a pitcher allows per nine innings.

It is given that In 2020, the pitcher had an ERA of 2.70.

A rate of earned runs to a fixed number of innings, n, which is also known as ERA.

Let's check it.

To determine a pitcher's earned run average or (ERA), multiply the runs by nine, then divide it by the number of innings pitched.

The runs earned in 2020 is 15 , let's multiply it by 9.

So , we get 15 × 9 = 135.

Now , divide it by number of innings which is 50.

So , the value of ERA will be equal to : 135 ÷ 50 = 27 which is also given in the question.

Now we will calculate the value of n.

So ,

n = (9 × Earned runs) / ERA

or

n = ( 9 × 15 ) / 2.7

n = 135 / 2.7

n = 50 innings

Therefore , value of n which is a constant representing number of innings is 50.

An item is $55 before sale, and bought for 45 percent off the regular price. therefore the sale price of item is  $30.25.

Markup is the amount that will be increased in the original price of the considered thing.

Markdown is the amount that will be decreased from the original price of the considered thing.

Think of "up" and "down" as increasing and decreasing prices respectively.

Given that item is $55 before sale, and bought for 45 percent off the regular price.

WE have to do that as; 45% off $55 implies subtract 45% from $55

= 45/100 × 55 = $24.75

therefore the item bought at $55 - $24.75= $30.25.

y = - [tex]\frac{\sqrt{111} }{20}[/tex]

Step-by-step explanation:

using Pythagoras' identity in the right triangle formed by the radius 1 and the given point, then

y² + (- [tex]\frac{17}{20}[/tex] )² = 1²

y² + [tex]\frac{289}{400}[/tex] = 1

y² = 1 - [tex]\frac{289}{400}[/tex] = [tex]\frac{111}{400}[/tex] ( take square root of both sides )

y = ± [tex]\sqrt{\frac{111}{400} }[/tex] = ± [tex]\frac{\sqrt{111} }{20}[/tex]

since the point is in the third quadrant then y < 0

and

[tex]p_{\mu,\nu}(x) = (x-z_1)^\mu (x-z_2)^\mu \cdots (x-z_\nu)^\mu[/tex]

The [tex]z_jz_k[/tex] terms occur in the coefficient of the [tex]x^{\mu\nu-2}[/tex] term, given by

(essentially due to Vieta's formulas)

With [tex]\mu=3[/tex] and [tex]\nu=673[/tex], we have

[tex]\displaystyle \left[x^{2017}\right] p_{3,673} = \binom32 \sum_{j=1}^{673} z_j^2 + 3^2 S \\\\ ~~~~ \implies S = \frac{19}9 - \frac13 \sum_{j=1}^{673} z_j^2 \\\\ ~~~~ \implies S = \frac{19}9 - \frac13 \left(\left(\sum_{j=1}^{673} z_j\right)^2 - 2 S\right) \\\\ ~~~~ \implies S = \frac{19}3 - \left(\sum_{j=1}^{673} z_j\right)^2[/tex]

The remaining sum on the right is the sum of the roots of [tex]\sqrt[3]{p_{3,673}(x)} = p_{1,673}(x)[/tex].

Recall that the sum of the roots of a polynomial

is [tex]-\frac{a_{n-1}}{a_n}[/tex]. Then the sum of the roots of [tex]p_{3,673}(x)[/tex] is -20, which is 3 times the sum of the roots (counting multiplicity) of [tex]p_{1,673}[/tex], so

[tex]\displaystyle \sum_{j=1}^{673} z_j = -\dfrac{20}3 \\\\ ~~~~ \implies S = \frac{19}3 - \left(-\frac{20}3\right)^2 = -\frac{343}9 \\\\ ~~~~ \implies |S| = \frac{343}9, m=343, n=9 \implies m+n = \boxed{352}[/tex]

Answer:

Step-by-step explanation:

The probability that a person chosen at random uses both internet connections is 1/9

Total number of people = 27

Number of people who use ADSL lines = 16

Number of people who use wireless internet = 15

Number of people who use neither of the two = 3

Let the number of people who use only ADSL lines and wireless internet be denoted by A and B respectively.

Then A + B + A∩B + 3 must be equal to 27

A + B + A∩B = 24

further, we can see that

(A + A∩B) = 16  

B + 16 = 24

B = 8

Also, (B + A∩B) = 15

8+ A∩B = 15

A∩B = 7

Thus, the number of people who use both internet connections = 7

Now, P(A∩B) = 7/27

= 1/9

Hence, probability that a person chosen at random uses both internet connections is 1/9.

The area of the composite shape that is given in the image below = 40 in.².

In the diagram given below, the shape can be decomposed into a triangle and a rectangle, since it is composed of both shapes.

Thus:

The area of the composite shape = area of rectangle + area of triangle.

Area of the triangle = 1/2(b)(h)

base = 12 - 7 = 5 in.

height = 5 - 3 = 2 in.

Area of the given triangle = 1/2(5)(2)

Area = 5 in.²

Area of the given rectangle = (l)(w)
