Answer:

the simplest form is 2/3

Step-by-step explanation:

[tex]\frac{2}{3}[/tex], is the correct answer.

[tex]\frac{10}{15}[/tex] can both be divided by 5. 10 ÷ 5 is 2 and 15 ÷ 5 is 3.

Answer:

20 feet

Step-by-step explanation:

Lance the alien is 5 feet tall. His shadow is 8 feet long. At the same time of day, a tree's shadow is 32 feet long. What is the height of the tree?

We solve this using proportion of

Height/ Shadow

= 5/8 = x/32

Cross Multiply

8x = 5 × 32

x = 5 × 32/8

x = 20 feet

The height of the tree is 20 feet

Answer:

Common Difference: [tex]-\frac{1}{2}[/tex]

The ninth term: -1

Step-by-step explanation:

The sequence can be written like this,

3, 2.5, 2, 1.5, 1, ....

Here the common difference is clearly -0.5 or [tex]-\frac{1}{2}[/tex], and we can conclude that [tex]n^{th}[/tex] number is [tex]3 - 0.5(n-1)[/tex]. So the 9th term is,

[tex]3 - 0.5(9 - 1)\\= -1[/tex]

Given:

[tex]\Delta FUN\cong \Delta TEA[/tex]

To find:

Identify the congruent corresponding parts of [tex]\angle N\cong \angle \_\_[/tex].

Solution:

We have,

[tex]\Delta FUN\cong \Delta TEA[/tex]

We know that corresponding parts of congruent triangles are congruent.

[tex]\angle F\cong \angle T[/tex]

[tex]\angle U\cong \angle E[/tex]

[tex]\angle N\cong \angle A[/tex]

Therefore, the required corresponding part is  [tex]\angle N\cong \angle A[/tex].

Answer: Simplifying a square root just means factoring out any perfect squares from the radicand, moving them to the left of the radical symbol, and leaving the other factor inside the radical symbol. If the number is a perfect square, then the radical sign will disappear once you write down its root. hope this helps can u give me brainliest or use this link it can help u

Answer:

  y = 95°

  x = 60°

Step-by-step explanation:

The applicable theorem is the one that says the exterior angle (120°) is the sum of the remote interior angles:

  120° = 25° +y

  95° = y . . . . . . . . . . subtract 25° from both sides

_____

If you like, you can get there by calculating x (or not):

  x = 180° -120°

  y = 180° -25° -x = 180° -25° -(180° -120°)

  y = 120° -25° . . . . . simplify — notice we didn't actually have to compute x

Answer:

950kg

Fruits = 3052.06

vegetables = 2712.94

$0.12

$0.44

Step-by-step explanation:

The first step is to determine the total tonnes of fruits and vegetables sold

7/12 x b = 2.28

b = 2.28 tonnes

Next we determine the tonnes of fruits sold

5/12 x 2.28 = 0.95 tonnes

Next we convert tonnes to kg

1 tonne = 1000kg

0.95 x 1000 = 950 kg

Money he received from selling fruits = 9/17 x $5765 = $3052.06

Money he received from selling vegetables = $5765 - $3052.06 = $2712.94

If price was reduced by 40%, price would be (100-40%) 60% of the original price

0.6 x 0.35 = $0.21

If price was increased by 25%, price would be (100 + 25) 125% of the original price

1.25 x 0.35 = $0.44

In this exercise we have to use the knowledge of finance and percentage to calculate the values ​​of vegetables and fruits:

A)[tex]950\ kg[/tex]

B)Fruits: [tex]\$ 3052.06[/tex] and Vegetables: [tex]\$ 2712.94[/tex]

C)[tex]\$0.12[/tex]

D)[tex]\$0.44[/tex]

The first step is to determine the total tonnes of fruits and vegetables sold:

[tex](7/12)*( b )= 2.28\\b = 2.28\ tonnes[/tex]

Next we determine the tonnes of fruits sold:

[tex](5/12)*( 2.28) = 0.95 \ tonnes[/tex]

Next we convert tonnes to kg:

[tex]1 \ tonne = 1000 \ kg\\(0.95)*( 1000) = 950\ kg[/tex]

If price was reduced by 40%, price would be 60% of the original price, so:

[tex](0.6)*(0.35) = \$0.21[/tex]

If price was increased by 25%, price would be 125% of the original price, will be:  

[tex](1.25)*(0.35) = \$0.44[/tex]

Answer:

Let the breadth be x and the length be y .

Original area =x.y

Now

length=y+2

breadth=x-2

Area=x.y-28 or x-2 × y+2

xy-28=(x-2)(y+2)

xy-28=xy+2x-2y-4

2y-2x=24

y-x=12

y=12+x

length=y-1

breadth=x+2

Area=xy+33 or (x+2)(y-1)

xy+33=(x+2)(y-1)

xy+33=xy-x+2y-2

35=2y-x

2y=35+x

y=(35+x)÷2

12+x=(35+x)÷2

24+2x=35+x

x=35-24

x=11

y=23

Therefore length is 23cm and breadth is 11cm

Answer:

2/9 - 1/6 = 1/18

Step-by-step explanation:

2/9= 4/18 and 1/6=3/18

so...

4/18-3/18=1/18

Hope This Helps!

Answer:

1/18

Step-by-step explanation:

find the LCD

= 18

say

18

= 18 ÷ 9

= 2

= 18 ÷6

= 3

now say

2 × 2 = 4

3 × 1 = 3

4-3/18

= 1/18

Collection increased by 78%.

Step-by-step explanation:

Last year number of vinyl records in Craig's collection = 63

Now he has number of vinyl records = 112

Number of vinyl records increased = 112 - 63 = 49

Percentage increase in his collection = [tex]\frac{\text{Number of records increase}}{\text{Number of records last year}}\times 100[/tex]

                                                               = [tex]\frac{49}{63}\times 100[/tex]

                                                               = 77.8

                                                               ≈ 78%

Therefore, his collection increased by 78%.

Answer: Acute

Step-by-step explanation: An acute triangle has three angles that each measure less than 90 degrees. An obtuse triangle is a triangle with one angle that is greater than 90 degrees. A right triangle is a triangle with one 90 degree angle.

Acute triangle, because if you draw out the triangle with the given lengths, each angle will be less than 90, which means it's an acute triangle.

Step-by-step explanation:

It can be convenient to use mental arithmetic methods* to fill in this table.

Since the relationship is proportional the y-value for x=4 will be half that for x=8, so will be 224/2 = 112. Similarly, the y-value for x=2 will be half that for x=4, so will be 112/2 = 56.

Then the y-value for x=6 will be the sum of the y-values for x=2 and x=4, so will be 112 +56 = 168.

If you actually care to find the "unit rate," you can divide the y-value for x=2 by 2 to get the corresponding y-value for x=1: 56/2 = 28. The unit rate is 28.

_____

* Multiplication or division by 2 is simply a matter of doubling or halving. In most cases, it is easy to double a number, or to compute half of it. (If it isn't, you need to review your arithmetic facts.)
