Find the sum. Write the sum as a mixed number, so the fractional part is less than 1. Number 3. 2 2/3 + 3 2/3 number 5. 9 3/6 + 2 2/6 number 7. 4 3/8 + 1 5/8

Answers

Answer 1

Answer:

See explanations below

Step-by-step explanation:

1)2 2/3 + 3 2/3

Convert to improper fraction

= 8/3 + 11/3

= (8+11)/3

= 19/3

= 6 1/3

hence the sum as mixed fraction is 6 1/3

2) 9 3/6 + 2 2/6

= 57/6 + 14/6

= (57+14)/6

= 71/6

= 11 5/6

Hence the value as a mixed fraction is 11 5/6

3) 4 3/8 + 1 5/8

= 35/8 + 13/8

= (35+13)/8

= 48/8

= 6

Hence the value is 6

A lamp post with a height of 12 ft casts a shadow of 6 ft. A fire hydrant near it casts a shadow that is 1.5 ft long. How tall is the fire hydrant?

Answers

Answer:

3ft

Step-by-step explanation:

We are given that

Height of lamp, h=12ft

Height of shadow, l=6ft

Height of shadow of hydrant, l'=1.5ft

Let height of hydrant=h'

We have to find the height of fire hydrant.

All right triangles are similar

When two triangles are similar then, the ratio of their corresponding sides are equal.

Using the property

[tex]\frac{h}{h'}=\frac{l}{l'}[/tex]

[tex]\frac{12}{h'}=\frac{6}{1.5}[/tex]

[tex]h'=\frac{12\times 1.5}{6}[/tex]

[tex]h'=3[/tex]ft

Hence, the height of fire hydrant=3 ft

The ratio of the length to the width the official german flag is 5:3.Sanda is making 12 german flags for a cuiture show.Each flag she makes has a length of 20 centimeters . It takes her 4 hours to make all the flag. What is the width of each flag and the average amount of time it takes sandra to make each flag?

Answers

Answer: The width of each flag = 12 cm

The average amount of time it takes Sandra to make each flag =  20 minutes.

Step-by-step explanation:

Given: The ratio of the length to the width the official german flag is 5:3.

Let length = 5x, width = 3x

Length of each flag = 20 cm

i.e. [tex]5x=20\Rightarrow\ x=\dfrac{20}{5}=4\text{ cm}[/tex]

Then width of each flag = 3 x 4 = 12 cm

i.e. width of each flag = 12 cm

Total time to make 12 flags = 4 hours

Time taken to make 1 flag = [tex]\dfrac{4}{12}[/tex] hour

Time taken to make 1 flag = [tex]\dfrac{1}{3}[/tex] hour

1 hour = 60 minutes

Time taken to make 1 flag = [tex]\dfrac{1}{3}\times60[/tex] minutes = 20 minutes.

Hence, the average amount of time it takes Sandra to make each flag =  20 minutes.

What is a polygon?

Polygon is defined as a geometric shape that is composed of 3 or more sides these sides are equal in length, and an equal measure of angle at the vertex,

Examples of polygons, equilateral triangles, squares, pentagons, etc

Here,
We can use the formula for the area of a regular pentagon to solve for the length of one side,
Area = (1/2) * Perimeter * Apothem

Since the pentagon is regular, all sides are equal, so we can write:

Perimeter = 5 * Length of one side

Substitute in the first expression

50 = (1/2) * 5 * Length of one side * 4

50 = 10 * Length of one side

Length of one side = 5

Step-by-step explanation:

General quadratic equation: y = ax² + bx + c.

When x = 0, y = -3.

=> (-3) = a(0)² + b(0) + c, c = -3.

We now have y = ax² + bx - 3.

When x = 2, y = -4.

=> (-4) = a(2)² + b(2) - 3, 4a + 2b - 3 = -4,

4a + 2b = -1.

Our 1st system of equations is 4a + 2b = -1.

When x = 4, y = -3.

=> (-3) = a(4)² + b(4) - 3, 16a + 4b - 3 = -3,

16a + 4b = 0, 4a + b = 0.

Our 2nd system of equations is 4a + b = 0.

Now we solve the system of equations:

4a + 2b = -1

- (4a + b = 0)

=> b = -1

Hence 4a + (-1) = 0, 4a = 1, a = 1/4. (B)

A car travels at an average speed of 68 miles per hour. How many miles does it travel in 5 hours and 45 minutes?

Step-by-step explanation:

There is 60 minutes every hour, so you divide by 60. 68 / 60 = 1.1333333333.

Now, we have to find out how many minutes there are in 5 hours and 45 minutes. Since there is 60 minutes every hour, 6 x 5 + 45 = 300 + 45 = 345. 1.1333333333 x 345 = 390.9999999885, rounded = 391.

Fortunately, when it comes to poetry, there are all sorts of good reasons to study it, especially from a Christian perspective! Not only does studying others effective use of language help us use our own to honor God and bring glory to Him, but, as you probably already know, large sections of the Bible are written in poetry. In fact, its estimated that one third of the Bible is poetry. (By contrast, the entire New Testament makes up less than one quarter of the Bible.) To quote John Piper, one of the most significant evangelicals of the 21st Century, God can raise the dead by any means he pleases. He can waken dull hearts to the reality of his beauty any way he desires. And one of the ways he pleases to do it is by inspiring his spokesmen to write poetry. Clearly, this should be an important topic for Christians to study!Now, if that fact seems surprising to you, it may be because the poetry in the Bible doesnt always look like our concept of poetry. Although they share some similarities, the Hebrew concept of poetry is quite different from ours. In this project, you will increase your familiarity with biblical poetry.Read the following article, Poetry and Wisdom Books of the Bible: The Beginners Guide by Jeffrey Kranz here: https://overviewbible.com/poetry/Then, consider the six books he discusses: Job, Proverbs, Ecclesiastes, Psalms, Song of Solomon, and Lamentations.
