Answer:

she needs 6 containers

Answer:

6 containers

Step-by-step explanation:

Unless there's more to the question, it's 6.

If you have 6 plates, and each container fits 1 plate, you'd need 6 containers to hold all the food

Answer:

The length of fencing Matias needs is 51 meters

Step-by-step explanation:

The given parameters are;

The dimensions of Matias' backyard from which half is to be turned into a chicken pen = 24 m by 45 m

The orientation of the fence that is will be made for the chicken pen = Stretch diagonally across the backyard (from a corner to the opposite corner)

From the question, Matias' backyard is rectangular in shape

Therefore, by Pythagoras theorem;

The length of the diagonal fence = √((24 m)² + (45 m)²) = 51 m

Matias needs 51 meters of fencing for the diagonal fence.

Answer:

13,000

Step-by-step explanation:

10% of the original purchase price of $130,000.

130,000 x .10 = 13,000

Answer:

40 cm.

Step-by-step explanation:

If 2 cups is 16 cm, and 4 cups are 20cm. You can multiply 4 by 2 to get 8. (20 x 2 = 40cm)

(16 divided by 2 = 8). ( 8 = the total length of each cup)

So...

( 8 cups are = to 40 cm)

Answer:

22

Step-by-step explanation:

22x4=44-4=40

Answer:

Step-by-step explanation:

s=y+29

s+y=773, using s from above makes this

y+29+y=773

2y+29=773

2y=744

y=372

So you have 372 stickers in your collection.

Answer:

where are the answer choices

Step-by-step explanation:

Answer:

2x + 3 = 7x + 4

3 + 2x = 7x + 4

3 + 2x = 4 + 7x

3 + 2x = 4 + 7x

3 + 2x + -7x = 4 + 7x + -7x

2x + -7x = -5x

3 + -5x = 4 + 7x + -7x

7x + -7x = 0

3 + -5x = 4 + 0

3 + -5x = 4

3 + -3 + -5x = 4 + -3

 3 + -3 = 0

0 + -5x = 4 + -3

-5x = 4 + -3

4 + -3 = 1

-5x = 1

 x = -0.2

Answer:

52

Step-by-step explanation:

the angles on any triangle together equal 180 degrees. add up the two angles you know (36+92) and you get 128 degrees. then subtract that (128) from 180 and you get 52. 52 degrees is the missing angle.

Answer:

78

Step-by-step explanation:

probability of getting a 5 which is 78.

Another way to look at this is that if we know the probability of the result being 5, then the probability of it not being 5 is just one minus that probability. We know that 5 is just one out of the 8 possibilities, so

P5=18

So the probability of not 5 is

Pnot5=1−P5=1−18=78

Answer:

19: 106

20: 79

21: 70

Step-by-step explanation:

Circle upper left

The central angles all add up to 360 degrees

BC + CD + 148 = 360

But CD = BC

2BC + 148 = 360            Subtract 148 from both sides

2BC = 360 - 148             Combine

2BC = 212                       Divide by 2

BC = 106

20

3 of the 5 arcs are marked as being equal.

Let each of them be called  = x

3x + 41 + 82 = 360          Combine

3x + 123  = 360                Subtract 123 from Both sides.

3x = 360 - 123

3x = 237

x = 237 / 3

x = 79

BC = 79

21

Unless DE and FC are diameters, this can't be solved. I will assume they are.

FB + 48 + 22 = 180.

FB + 70 = 180

FB = 110

===========

FC = FB + BD + DC

180 = 110 + 22 + DC

180 = 132 + DC

DC = 180 - 132

DC = 48

===========

BC = BD + DC

BC = 22 + 48

BC = 70

Answer:

Stratified random sampling

Answer:

You would have to look at the explanation since there are multiple

Step-by-step explanation:

-7x + 1 would have to be greater than or equal to 15.

-7(2) + 1 = 15 so you would mark a filled in dot at 2 and point an arrow going to the right.

6x + 3 must be greater than or equal to -21.

6(-4) + 3 would equal -21 so you would mark a filled in dot at negative 4 with an arrow going to the right.

Step-by-step explanation:

Answer:

[tex]y = 100 * (0.75)^{30[/tex]

Step-by-step explanation:

Given

[tex]a =100[/tex] --- Initial Amount

[tex]r= 25\%[/tex] every 10 years

Required

The remaining amount after 300 years

To do this, we make use of:

[tex]y = a(1 - r)^T[/tex]

Where

r = decay rate

T = the period of decay

In 300 years, there are 30 periods of 10 years.

i.e.

[tex]T = \frac{300}{10}[/tex]

[tex]T = 30[/tex]

[tex]y = a(1 - r)^T[/tex]

[tex]y = 100 * (1 - 25\%)^{30[/tex]

[tex]y = 100 * (1 - 0.25)^{30[/tex]

[tex]y = 100 * (0.75)^{30[/tex]

Answer:

answer is C

Step-by-step explanation:

Answer:

AD = 1.96

BD = 6.72

CD = 23.04

Step-by-step explanation:

7/25 = AD/7

25AD = 49

AD = 1.96

24/25 = BD/7

25BD = 168

BD = 6.72

CD = 25 - 1.96 = 23.04

Answer:

x = 4

Step-by-step explanation:

A trapezium is a quadrilateral (has four sides and four angles) with one pair of parallel sides. A trapezium is said to be isosceles if the bases are parallel, the two other sides known as the legs are equal and diagonals of the trapezium are equal to each other.

In trapezoid ABCD, BC and AD are the diagonals.

Hence BC = AD (property of isosceles trapezoid)

9x + 1 = 12x - 11

Simplifying:

12x - 9x = 1 + 11

3x = 12

Dividing both sides by 2:

x = 4

Answer:

6x + 7 - 2x + 2 + 3x

= 6x -2x + 3x +7 + 2

9x - 2x + 9

7x + 9

7x = -9

x = -9/7
