Answer:

2.5*2.5

Step-by-step explanation:

You want to frost a 13 in. by 9 in. cake that you just baked when you notice your little brother ate a piece right out of the middle. What area of cake is left to be frosted if he ate a 2 in. by 2 in. piece? no links pls :) thanks will give brainliest

Answers

Answer:

113 inches

Step-by-step explanation:

13 times 9 is 117 inches (this is the area for the whole cake)

2 times 2 is 4 (this is just the middle)

But since the brother ate the middle you will have to subtract the area of the middle piece from the whole area.

117-4 is 113 so the area now is 113 inches

The polygons are similar, but not necessarily drawn to scale. Find the value of x.


question 3/4

Answers

Answer:

i am having trouble with that too

Step-by-step explanation:

Answer:

Since we are told that the two given polygons are said to  similar, their corresponding side lengths are proportional to each other.

so to solve

(x - 3)/2.5 = 16/4

(x - 3)/2.5 = 4

Multiply both sides by 2.5

x - 3 = 4 × 2.5

x - 3 = 10

Add 3 to both sides

x = 10 + 3

x = 13

So the value of x is 13.

Solve the simultaneous equation:
2x+3y=13

X+2y=9​

Answers

Answer:

2x + 3y = 13

4x - y = -2

In the second equation, subtract 4x from both sides.

-y = -2 - 4x

Divide both sides by -1.

y = 2 + 4x

Put this into the first equation in place of y.

2x + 3(2 + 4x) = 13

Multiply everything in the parenthesis by 3.

2x + 6 + 12x = 13

Combine like terms.

14x + 6 = 13

Subtract 6 from both sides.

14x = 7

Divide 14 on both sides.

x = 7 / 14

x = 0.5

Put this into the second equation in place of x.

4(0.5) - y = -2

2 - y = -2

Subtract 2 from both sides.

-y = -4

Divide both sides by -1.

y = 4

So x = 0.5 and y = 4.

What is the volume of a hemisphere with a radius of 60.7 m, rounded to the nearest tenth of a cubic meter?

Answers

Answer:

468408.4m

Step-by-step explanation:

The guy above knows

The volume of a hemisphere with a radius of 60.7 m is 468170.95 cubic meter.

What is the volume?

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

Given that, a radius of a hemisphere is 60.7 m.

Half of a sphere, or a hemisphere, is a three-dimensional (3D) shape. The form we obtain when a sphere is split by a plane going through its centre is known as a hemisphere. A hemisphere has one flat circular base and a curving surface. The quantity of unit cubes that can fit inside a hemisphere is known as its volume.

We know that, the volume of a hemisphere is (2/3)πr³.

Here, volume is 2/3 ×3.14×60.7³

= 2/3 ×3.14×223648.543

= 468170.95 cubic meter

Therefore, the volume is 468170.95 cubic meter.

60 tickets to a concert was sold. Adult tickets cost $5 while children’s tickets cost $3.50. A total of $250 was collected. How many adult and children tickets were sold?

Answers

Answer:

Number of adults tickets sold = x

= 26.67 tickets

Number of children tickets sold = y = 33.33 tickets

Step-by-step explanation:

Let

Number of adults tickets sold = x

Number of children tickets sold = y

x + y = 60 (1)

5x + 3.50y = 250 (2)

From (1)

x = 60 - y

Substitute x = 60 - y into (2)

5x + 3.50y = 250

5(60 - y) + 3.50y = 250

300 - 5y + 3.50y = 250

- 5y + 3.50y = 250 - 300

- 1.50y = 50

y = -50/-1.50

y = 33.33

Substitute y = 33.33 into 1

x + y = 60

x + 33.33 = 60

x = 60 - 33.33

x = 26.67 tickets

Number of adults tickets sold = x

= 26.67 tickets

Number of children tickets sold = y = 33.33 tickets

Al principio Eduardo y Adrián tenían el mismo número de dulces. Eduardo le dio a Adrián la mitad de los dulces que tenía. Después, Adrián le dio a Eduardo la mitad de los dulces que tenía él en ese momento, así que a Adrián le quedaron 12 dulces. ¿Cuántos dulces tenía Eduardo al final? *

Answers

Answer:

Al final, Eduardo tenía 20 dulces.

Step-by-step explanation:

Dado que al principio Eduardo y Adrián tenían el mismo número de dulces, y Eduardo le dio a Adrián la mitad de los dulces que tenía, y después, Adrián le dio a Eduardo la mitad de los dulces que tenía él en ese momento, así que a Adrián le quedaron 12 dulces, para determinar cuántos dulces tenía Eduardo al final se debe realizar el siguiente cálculo:

Eduardo 1X = Adrián 1X

Eduardo 0.5X = Adrián 1.5X

Eduardo 1.25X = Adrián 0.75X

0.75 X = 12

X = 12 / 0.75

X = 16

1.25 X = 16 x 1.25 = 20

Así, al final, Eduardo tenía 20 dulces.

m∠1 = 180° - 52°

m∠1 = 128°

m∠3 = 47° [Alternate interior angles]

m∠5 + 52° + 47° = 180° [Sum of linear angles is 180°]

m∠5 = 180° - 99°
