Answer:

i think 1/4

Step-by-step explanation:

Answer:

[tex]\frac{1}{4}[/tex]

Step-by-step explanation:

We name the coins coin 1 and coin 2 for the sake of simplicity.

There are four possible situations:

coin 1 head, coin 2 head

coin 1 head, coin 2 tails

coin 1 tails, coin 2 head

coin 1 tails, coin 2 tails

Only case 1 results in both 'heads'. So the probability is 1/4.

Work out the area of the trapezium ABDE.

Answers

Answer:

(half * base 1 * base 2)/height

base 1 is 6 and base 2 is 9

get the height from similarity

6/9 = 8/CE

therefore CE = 72/6

Answer:

30cm²

Step-by-step explanation:

AE/BD = CE/CD

9/6 = CE/8

CE = 9/6 x 8

CE = 12cm

DE = CE - CD

DE = 12 - 8 = 4 cm

½(6 + 9)4 = 30cm²

........................​

Answers

Answer:

Step-by-step explanation:

Figure (1)

x° = 107° [Vertically opposite angles]

Since, vertical angles are equal in measure.

Figure (2)

x + 71° = 90° [Given, complementary angles]

x = 90° - 71°

x = 19°

Figure (3)

x + 21° = 180° [Given as supplementary angles]

x = 180° - 21°

x = 159°

Figure (4)

x = 129° [Vertical angles]

Figure (5)

x° = 90° [Given]

z° + 34° = 90°

z° = 90° - 34°

z° = 56°

Since, x° + y° + z° = 180° [Linear angles]

90° + y° + 56° = 180°

y° + 146° = 180°

y° = 180° - 146°

y° = 34°

Carmen deposits $4000 into an account that pays simple interest at a rate of 3% per year. How much interest will she be paid in the first 3 years?

Answers

Answer:

$360

Step-by-step explanation:

I = Prt

I = 4000 * 3 * 3%

I = 12000 * 3% (Convert 9000 and 3% into fractions.)

I =12000/1 * 3/100 (100 and 12000 have a GCF of 100)

I = 120/1 * 3/1 (Disregard the over 1 portion.)

I = 120 * 3 (Multiply 120 by 3 to get 360.)

I = $360

Answers

Answer:

y=x+4

Step-by-step explanation:

Slope intercept is y= mx+b

The slope is rise/run or change in y/change in x. Here the slope is 1 since when y goes up1, x goes to the right 1 (1/1=1).

The y intercept is 4 since it hits the y axis at 4.

so it would be y= 1x+4 which is y=x+4

Answer is 4X^3 Y^5
Steps
4^2 = 16
X^6
Y^10

Answer and Step-by-step explanation:

The square root of 16 times x to the power of 6 times y to the power of 10 is the same as:

[tex]\sqrt{16x^{6} y^{10} } = \sqrt{16} * \sqrt{x^{6} } * \sqrt{y^{10} }[/tex]

The square root of 16 is 4.

The square root of x to the power of 6 is x to the power of 3.

The square root of y to the power of 10 is x to the power of 5.

So, the answer is:

[tex]4x^{3} y^{5}[/tex]

Answer:

[tex]x = 18[/tex]

Step-by-step explanation:

Given

[tex]\frac{x}{6} - 7 = -4[/tex]

Required

Solve for x

[tex]\frac{x}{6} - 7 = -4[/tex]

Add 7 to both sides

[tex]\frac{x}{6} - 7+7 = -4+7[/tex]

[tex]\frac{x}{6} = -4+7[/tex]

[tex]\frac{x}{6} = 3[/tex]

Multiply through by 6

[tex]6 * \frac{x}{6} = 3 * 6[/tex]

[tex]x = 3 * 6[/tex]

[tex]x = 18[/tex]
