Estimate The Area Of The Irregular Shape. Explain Your Method And Show Your Work. Will Mark Brainliest

Answers

Answer 1

9514 1404 393

Answer:

  29 square units

Step-by-step explanation:

One estimate could be obtained by approximating the shape by a polygon with vertices at ...

  (-3, 3), (2, 2), (2, -2), (-3, -4), (-4, -3), (-3, -1)

The idea is to try to have about as much area outside this boundary as inside with reference to the curve shown.

This can be subdivided into a trapezoid with the first four vertices shown, and a triangle with the last three vertices shown. The respective areas are ...

  trapezoid area = 1/2(b1 +b2)h = 1/2(7+4)(5) = 27.5

  triangle area = 1/2bh = 1/2(3)(1) = 1.5

Then the total estimated area is about 27.5 +1.5 = 29 square units.

Answer:

  see attached

Step-by-step explanation:

a) One way you can try to identify the pattern is to look for the differences between the images shown, then divide those differences by 2. For example, the total number of vertical dots is 2, then 4 in patterns 2 and 4. This suggests the total number of vertical dots is equal to the pattern number..

The total number of horizontal dots is 4, then 6 in patterns 2 and 4. This suggests that the number of horizontal dots increases by 1 in each pattern. This would mean pattern 1 would have 3 total horizontal dots and 1 total vertical dot. It will look like one row of 3 dots.

Pattern 3 will have 5 total horizontal dots and 3 total vertical dots. The sequence of patterns will look like the attachment.

__

b) The total number of dots in each pattern is 2×(pattern number) +1. Then the number of dots in Pattern 7 will be 2×7 +1 = 15 dots.

Carrie is making a colorful beaded necklace. She has 3 times as many green beads
as red beads, and twice as many blue beads beads. If she has 150 beads
all together, how many of the beads are green?

Answers

Answer:

45 green beads

.

Step-by-step explanation:

Let the number of red beads be 'x'

Given that, Carrie has 3 times as many green beads as red beads

Number of green beads = 3 times number of red beads

Number of green beads = 3x

She 2 as many blue beads as green beads

Number of blue beads = 2 times the number of green beads

Number of blue beads = 2(3x) = 6x

She has 150 total

Therefore,

Number of red beads + Number of green beads + Number of blue beads = 150

x + 3x + 6x = 150

10x = 150

x = 15

Thus, number of green beads = 3x = 3(15) = 45

Thus there are 45 green beads

I hope this helps

The question requires finding total green beads she has

There are 45 green beads

let

number of red beads = x

number of green beads = 3x

number of blue beads = 2(3x)

Total beads = 150

Total beads = red beads + green beads + blue beads

150 = x + 3x + 2(3x)

150 = 4x + 6x

150 = 10x

divide both sides by 10

x = 150/10

x = 15

Therefore,

number of red beads = x

= 15 beads

number of green beads = 3x

= 3 × 15

= 45 beads

number of blue beads = 2(3x)

= 2(3 × 15)

= 2(45)

= 90

A contractor purchases 6 dozen pairs of padded work gloves for ​$80.64. He incorrectly calculates the unit price as ​$13.44 per pair for the expense report. What is the correct unit​ price? What is the​ error?

Answers

Answer:

Reggie records the lengths of different fabrics he has.

Answers

1/8+1/4+3(1/2)+2(5/8)+4(3/4)=49/8
49/8-11/4=27/8

Reggie is left with [tex]\dfrac{27}{8}[/tex] yarns of fabric.

The total length of fabrics =  [tex]\dfrac{1}{8}+\dfrac{1}{4}+3\dfrac{1}{2}+2\dfrac{5}{8}+4\dfrac{3}{4}[/tex]

                                            =  [tex]\dfrac{1}{8}+\dfrac{1}{4}+\dfrac{7}{2}+\dfrac{21}{8}+\dfrac{19}{4}[/tex]

The LCM of 4 and 8 is 8.

So, the expressions will be simplified by adding all the terms with the same denominator.

                      = [tex]\dfrac{49}{8}[/tex]

The fabric used by Reggie = [tex]2\dfrac{3}{4}[/tex]

                                              = [tex]\dfrac{11}{4}[/tex]

The fabric left can be calculated by subtracting the total fabric he used from the total fabric he had.

Fabric left =[tex]\dfrac{49}{8} - \dfrac{11}{4}[/tex]

The LCM of 8 and 4 is 8

Fabric left = [tex]\dfrac{49}{8} - \dfrac{22}{8}[/tex]

                 =  [tex]\dfrac{27}{8}[/tex]

So, he is left with [tex]\dfrac{27}{8}[/tex] yarns of fabric.

Answer:

Step-by-step explanation:

Let the distance from A to BC be represented by y, and the distance DE be represented by x. We can write some relations using the definition of the tangent of an angle, and the double-angle formula for tangent. The double-angles are complementary

Left angles

Call the smaller angle α. Then the larger angle is 2α.

  tan(α) = x/2

  tan(2α) = 2tan(α)/(1 -tan(α)²) = 2(x/2)/(1 -(x/2)²) = 4x/(4 -x²)

Right angles

  tan(β) = x/3

  tan(2β) = 2tan(β)/(1 -tan(β)²) = 2(x/3)/(1 -(x/3)²) = 6x/(9 -x²)

__

Angles 2α and 2β are complementary, so the product of their tangents is 1.

  (4x/(4 -x²))(6x/(9 -x²)) = 1

  24x² = (4 -x²)(9 -x²) . . . . multiply by the product of denominators

  x⁴ -37x² +36 = 0 . . . . . put in standard form

  (x² -36)(x² -1) = 0 . . . . . factor

Solutions to this equation are x = ±1 and x = ±6. Only positive values less than 1.25 can possibly satisfy the geometry. Hence x = DE = 1.

The length of DE is 1.

What is unit conversion?

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

For example conversion of a kilometer to a meter is to multiply by 1000 but meter and kilometer both unit is for distance only.

Given the speed of an airplane  = 260 m/sec

Since,

1 mile = 1.60934 kilometer

1 km = 1000 meter

So,

1 mile = 1609.34 meter

1 m = (1/1609.34) mile

And,

1 hour = 360 seconds

1 s = (1/360)hour

So,

260 m/sec = 260 (3600/1609.34) miles/hour

⇒ 581.60 miles/hour.

Hence "The speed of an airplane in miles per hour is 581.60 miles/hour".

A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).

First row:

Months (input) and Days (output) = not a function. The month of February has two corresponding outputs: Days of 28 and 29.

A natural gas company charges a fixed customer fee of $ 12.60 every

a. Using x as the number of units used in a month and y as the total
monthly cost, write an equation

Answers

Y=12.60+0.64x

$0.64 is charged for each unit which is represented by x. Therefore .64 is multiplied by x. 12.60 is the charge you have no matter what every month. So if you don’t use any gas you would still pay $12.60.

y = 12.60 + 0.64x

Step-by-step explanation:

y = $12.60 + $0.64(x)

If f(x) = 2x and g(x) = 5x + 2, what is (f + g)(x) when x = 3?

Answers

Answer:

f÷g=2x+5x+2=7x+2

x=3

7×3+2=21+2=23

The value of  (f + g)(x) when x = 3, if f(x) = 2x and g(x) = 5x + 2, is 23.

What is function?

The function is a relationship between a set of potential outputs and a set of possible inputs, where each input has a single relationship with each output. This means that if an object x is present in the set of inputs (also known as the domain), then a function f will map that object to exactly one object f(x) in the set of potential outputs (called the co-domain).

Given:

f(x) = 2x and g(x) = 5x + 2

Calculate  (f + g)(x)  as shown below,

f(x) + g(x) = 2x + 5x +2

f(x) + g(x) = 7x + 2

Put x = 3

f(3) + g(3) = 7 × 3 + 2

f(3) + g(3) = 23
